Effect of dispersion characteristics of suspended solids
on the parameters of surface runoff treatment

Summary

Quantitative and dispersion characteristics of insoluble pollutants in rainfall and snow-melt water and its effect on the parameters of removing pollutants from water by sedimentation, chemical free and chemical filtration are considered. It is shown that the concentration of suspended solids in surface runoff multiply exceeds the concentration of oil products whereupon these pollutants are present in the form of two-component particles. In the particles oil products or inorganic admixtures can be adsorbed components, and during sedimentation of surface runoff suspended solids and oil products are being removed synchronically. The concentration and kinetic consistency of suspended solids from residential areas are lower than those from highways; which reduces the sedimentation time in the storage settling tank and concentration of pollutants in settled water. During 1–3 days of settling tank empting monotonic reduction of suspended solids concentration in settled water before filtration occurs. Fluctuation range depends on the sedimentation time in the settling tank, initial suspended solids concentration and tank empting time. The use of coagulants before filtration of settled surface runoff from highways provides for improving the treatment efficiency and obtaining sustained quality of filtered water.

Gabion filtration facilities for surface runoff treatment

Summary

The design and characteristics of gabion filtration treatment facilities developed and designed by the specialists of «ECOLANDSHAFT-XXI century» NPO LLC are presented. The analysis of wastewater and effluent samples collected at different seasons of the year from the inlet and outlet of the different gabion facilities showed that the efficiency of treatment both in terms of suspended solids and oil products and COD, BOD5 met the maximum permissible pollutant concentrations set for fishery waters. Gabion facilities are open gravity facilities, which do not require any chemicals, pumps, electricity or premises for their operation. They include two sections, each of them having four treatment stages: accumulating settling tank; filtration chamber with granular bed; bioplato; filtration chamber with sorbent. Gabion facilities include bioplato as a mandatory and very important element for treatment which is a shallow impoundment seeded with macrophytes and which ensures removing a number of pollutants. Due to the use of gabions, bioplato and chemical free treatment the gabion facilities can be qualified as nature like facilities which can be retrofitted into the landscape and have an attractive look becoming a part of the landscape. By now more than 120 gabion filtration treatment facilities with up to 15 years service time have been designed and built. The facilities provide for the treatment of surface runoff from highways, industrial sites of technology and industrial parks.

Study of the dynamics of surface runoff composition of the urban lands

Summary

The qualitative composition of surface runoff of urban lands is affected by significant fluctuations. Studying its dynamics, determining possible regularities and causes of these fluctuations can be conveniently carried out with the use of the mathematical apparatus of the time series analysis. The procedure of seasonal decomposition was applied to the time series of monthly dynamics with the annual periodicity of seasonal fluctuations with the help of the multiplicative model. The results of the quantitative chemical analysis of surface runoff at the «XXII Party Congress» outfall of the Samara municipality for 2004–2016 were used as benchmark data. As a result of the performed analysis the occurrence of the seasonal regularities of the surface runoff composition changes was determined. The seasonal indices of 15 effluent quality parameters were determined: BODfull, suspended solids, mineralization, chlorides, sulfates, ammonium ion, nitrite ion, nitrate anion, phosphates (as phosphorus), total iron, copper, zinc, aluminium, oil products, and detergents (anionic). Based on the given seasonal decomposition of the time series the qualitative assessment of the effect of the trend, seasonal and random components on the unsteadiness of the surface runoff quality parameters was performed.

Study of oil products and heavy metals removal from surface runoff in phytofilters

Summary

Internationally the use of bioengineered facilities including phytofilters in the treatment of surface runoff from urban lands is gaining ground. The use of phytofilters in moderate climate belts has some restrictions related to the decline in treatment efficiency during the periods of near-zero temperatures because of the retardation of biochemical processes in plants and soil microorganisms. A technical solution of the described problem is proposed that consists in adding materials with sorption and ion-exchange properties (peat and zeolite) into the filter media. The efficiency of removing oil products and heavy metals (lead, copper, aluminium, iron) from the simulated solution of surface runoff in a pilot laboratory phytofiltration plant with the use of higher plants: common reed grass (Phragmites commnis), mace reed (Tpha latiflia) and Iris pseudacorus was studied. The efficiency of removing oil products was 95.5–98.9%, and that of heavy metals – 66–99.3%. It was stated that during the vegetation period partial phytoregeneration of the filtration media from the trapped oil products and heavy metals occurs under the effect of higher plants and rhizospheric microflora. By experiment it was determined that the efficiency of phytoregeneration from oil products decreases in series: common reed grass – Iris pseudacorus – mace reed; from heavy metals: Iris pseudacorus – common reed grass.

The experience of operating surface runoff treatment facilities
and the guidelines for the improvement of sludge treatment technology

Swimmer

The data on the mechanical and physical properties of surface runoff sludge generated on the lands allotted for settlement and highways is presented. The observations of the processes of natural sludge drying on the sand sludge dewatering beds at the treatment facilities show that the sludge is characterized by low dewatering properties (more than 89–94%), and this fact stipulates the demand for the improvement of the sludge treatment technology. As a result of the chemical and analytical studies of the surface runoff sludge composition it was stated that the sludge from industrial sites located in the residential districts and industrial areas, from residential constructions on the lands allocated for settlement with parklands as well as from the recreation areas with nature-sanctuaries could be attributed to class IV of hazard (low-hazard). Sludge from the territory of the Moscow Ring Road, gasoline stations, and parking lots at the shopping malls could be attributed to class III of hazard (moderately hazardous). The results of the laboratory studies showed that the use of high molecular polyelectrolytes provided for sludge thickening and efficient dewatering by centrifuging to 74–82% moisture content. The design data on the sludge specific volume (98–99% moisture content) generated in storage tanks is presented as well as the data on the specific volume of dewatered sludge (89–94 % moisture content) generated annually on 1 ha catchment area for different types of catchment areas. It is recommended during the design process not to remove water charged sludge with a moisture content of 98–99% by trucks (sludge pumps) as an expensive and ineffective method, but to dewater sludge directly at the treatment facilities with the use of stationary or mobile mechanical equipment (vacuum-filters, filter-presses, centrifuges, geotubes).

Municipal surface runoff treatment in Baku

Summary

A number of problems related to establishing a centralized system of surface runoff treatment from built-up areas by the example of Baku under the conditions of the regulated inflow with the restoration of the functions of the operating separate wastewater disposal system are considered. A process flow scheme of the centralized treatment of surface runoff with placing treatment facilities in two locations has been developed. The location of one of the treatment plants is planned near the Azerbaijan Bay; it is designed for chemical free treatment by sedimentation and filtration of surface runoff from a group of sewers in the central part of the city in case of using part of the effluent for the municipal landscape irrigation; in case of discharging the effluent into the sea chemical treatment is applied. The second plant is planned to build outside the city on the basis of the operating treatment facilities of Zykh community with subsequent tertiary effluent treatment at the municipal treatment facilities. The efficiency of the basic elements of the surface runoff treatment and tertiary treatment scheme at the first plant was studied on the basis of the experimental tests of sedimentation and tertiary treatment by filt­ration through floating foamed polystyrene bed. Upgrade and re-equipment of the wastewater disposal systems is one of the most complicated engineering tasks focused on improving the environmental situation and protecting the municipal coastland from pollution with surface runoff. Establishing the scheme of surface runoff removal and treatment from the built-up Baku area with installing trunk storm sewers, separation chambers and regulating tanks will provide at last for the solution of the most important environmental problem.

Purification of storm water from the territories of industrial enterprises

Summary

The state of surface runoff disposal systems in Russia has been considered. In many cities the systems of atmospheric precipitation removal are in an extremely unsatisfactory condition since they have hardly undergone any upgrade. During intensive precipitation and heavy snowmelt rain and melt water accumulate on the territory of industrial enterprises. At the same time the treatment of surface runoff is complicated by the increase in volumes of wastewater and the physical deterioration of treatment facilities. As a result surface runoff containing suspended solids, oil products and other pollutants enters water bodies without treatment producing a negative impact on the ecosystem of water bodies. The characteristic of the composition of surface runoff of industrial enterprises is given on the example of a coal preparation plant in the city of Novosibirsk. Methods of treatment are considered. In order to reduce the harmful effects of surface runoff on water bodies at the Novosibirsk State University of Architecture and Civil Engineering (Sibstrin) storm water treatment technology has been developed that provides for the effluent discharge into open water bodies or usage in recirculating water supply of enterprises.

Development of the Regional program  of protecting Moscow water bodies from pollution with surface runoff

Summary

The description of the Moscow system of surface runoff disposal and treatment characterized by the extensive use of the urban hyd­rographical system as elements of the drainage network is presented. Nowadays the system is positioned as «urban collector-river drainage system» that encompasses up to 90% of the Moscow territory within its old boundaries. It is noted that surface runoff from the developed areas, properly collected and diffused, is a main source of technogenic pollution and degradation of the water bodies in Moscow in the city area. Under current conditions improving their ecological state is possible only by the implementation of measures on reducing the anthropogenic impact on the water bodies and their catchment basins; eliminating the accumulated environmental damage; restoring the self-purification capacity and protecting underground water from pollution. To perform these tasks the Regional program of protecting the Moscow water bodies from surface runoff pollution basing on the principles of regulating the discharge of pollutants on the basis of the best available techniques of wastewater treatment is proposed. In the process of developing the Regional program together with the information-technical reference book ITS 10-2015 «Wastewater treatment with the use of public wastewater disposal systems of settlements, urban districts» a number of governmental bylaws developed and adopted in furtherance of the provisions of Federal  Laws No. 219-FZ and No. 416-FZ should be also taken into account.
