Functional purpose of the landfill

The intermunicipal landfill for solid domestic waste is a special facility designed for the isolation and disposal of solid domestic waste (MSW), taking into account engineering measures that ensure the sanitary and epidemiological safety of the landfill site and adjacent natural areas. The landfill provides a comprehensive solution to the issues of waste disposal from the population.

Information about the need of the landfill for solid waste in the main energy resources

Domestic water supply to the solid waste landfill is provided by imported water. In the premises of administrative buildings (change houses) 2 containers with a capacity of 110 liters are installed. Water supply is carried out as needed by tank trucks. Additionally, for drinking at the rate of 2 liters per person per day, bottled water is delivered once a week in the amount of 90 liters (18 bottles of 5 liters each). Industrial water at the landfill is used for humidification during fire periods to prevent possible waste ignition or smoldering. The source of technical water supply is water settled and clarified in the control and regulation pond. Estimated water consumption for a period of 6 months for moistening the pits of MSW is 36 m3/day. (total volume 6480 m3). For firefighting, 2 fire tanks with a capacity of 60 m3 each are designed. The tanks are filled with imported water. The nearest fire station is located at a distance of 5 km from the projected solid waste landfill, the time of arrival of fire brigades does not exceed the established standards (app. TO). The power supply of the landfill site for municipal solid waste will be provided from the projected diesel power plant to buildings and structures by a cable laid in a trench. Key indicators for power supply: installed capacity - 60,62 kW; design power - 43,64 kW; annual electricity consumption - 238,5 thousand. kW/h The main consumers of electricity are: outdoor electric lighting; electrical consumers of domestic premises, a checkpoint, a garage for parking machines and mechanisms (bulldozer, dump truck). Gas consumption at the landfill is not envisaged. On the territory of the landfill there are: bulldozer ShanTui SD13 for the formation of working maps and insulating layers - 1 pc. excavator EO 2621 (bucket capacity 0,25 m3) for excavation and loading of insulation soil into a dump truck - 1 pc. dump truck KAMAZ-55111 with a body capacity of 6,6 m3 for transportation of insulation soil - 1 pc. Garbage delivery is carried out by: dump truck KAMAZ-55111 with a body capacity of 6,6 m3 for transportation of insulation soil - 7 pcs. For the full operation of the bulldozer, fuels and lubricants are required - in the first year of operation: diesel fuel 5,02 t/year, lubricants 0,91 t/year, cleaning materials 0,026 t/year; in the last year: diesel fuel 8,76 tons/year, lubricants 1,58 tons/year, cleaning materials 0,05 tons/year. For the full operation of the excavator, fuels and lubricants are required - diesel fuel 1,8 tons / year; lubricants 0,08 t/year; cleaning materials 0,003 t/year. For the full-fledged operation of a dump truck moving insulation soil, fuels and lubricants are required - diesel fuel 0,57 tons / year; lubricants 0,08 t/year; cleaning materials 0,006 t/year. The total amount of fuel and lubricants for the most productive year of operation is required: diesel fuel 11,13 tons/year; lubricants 1,66 t/year; cleaning materials 0,059 t/year. Refueling of fuel and lubricants for equipment operating at the landfill is carried out outside the landfill at the nearest gas station.  

Data on the design capacity of the landfill

The production capacities of the inter-municipal solid waste disposal site provide a comprehensive solution to the issues of waste disposal from the population. Municipal solid waste (MSW) - objects or goods that have lost their consumer properties, which are formed during the life of the population. MSW is divided into waste (biological MSW) and garbage itself (non-biological MSW of artificial or natural origin). Waste disposal - disposal of waste that is not subject to further use in special storage facilities in order to prevent the ingress of harmful substances into the environment: air; ground, underground and surface waters; soils and soils. Information about the morphological composition of MSW, hazard classes and code in accordance with the FCC entering the landfill is presented in Appendix G. The life of the landfill is 20 years. The operation mode of the landfill is envisaged year-round - 365 days a year in 1 shift (8 hours). Waste is transported to the landfill 5 days a week (252 days a year). The annual specific increase in MSW compared to the volume of the previous year is 3%. The annual amount of solid waste entering the landfill in the first year of operation is 26860 m3, in the last year of operation - 47100 m3. The total amount of waste entering the landfill and subject to disposal during the operation of the landfill is 721740 m3 in an uncompacted state (density 0,2 t/m3). For the delivery of solid waste during the period of operation, a KAMAZ-55111 dump truck with a body capacity of 6,6 m3 was adopted. The ShanTui SD13 bulldozer shifts the unloaded solid waste onto a working map, creating layers 0,5 m thick and compacting them with a 4-fold passage of the bulldozer in one place. In accordance with paragraph 2.4 [5], it is assumed that compacted solid waste is poured 2,0 m high with a layer of local mineral soil 0,25 m high with compaction by a ShanTui SD13 bulldozer. Excavation soil formed during the construction of solid waste pits, stored into piles. The development of soil for the isolation of MSW in piles is carried out by an EO 2621 excavator (front shovel bucket). The soil is moved to the isolated map by a KAMAZ-55111 dump truck with a body capacity of 6,6 m3. Each pit is divided into working maps. Dump trucks arriving at the landfill are unloaded in front of the work map at the place of storage of solid waste. The work card has a minimum width of 5,0 m and a length of 30,0 m. The area in front of the work card where unloading is carried out is assumed to be the same length of 30 m and a width of 13 m. The actual capacity of the landfill is 265 m086 of solid waste in a compacted state (3 .0,74 t/m3), taking into account the insulating layers, which ensures the storage of the required volume of solid waste 253 m860 in a compacted state (3 t/m0,74), taking into account the insulating layers. In accordance with the “Recommendations on the rationing of labor for employees of external improvement enterprises”, the standard for the number of managers, specialists, employees and workers for landfills with a given volume of waste disposal should be provided by a staff of 9 people. 

Information about the complex use of raw materials, secondary energy resources, production waste

At the production area, water is used for irrigation (moistening) of MSW to prevent fire at these sites. The source of technical water supply is water settled and clarified in the control and regulation pond. Process water is recycled. Surface runoff from the economic zone, in the amount of 422,23 m3 / year, enters the drainage well, from there it is directed by gravity to the septic tank No. 2, with a capacity of 10 m3. The compost mass from the dry closet, in the amount of 0,61 m3/year, is taken out by a sewage truck to the sewage treatment plant in Borodino (Appendix M). Domestic wastewater from the washbasin and generated during cleaning and disinfection of the premises of the change houses, in the amount of 52,56 m3 / year, is discharged into septic tank No. 1, with a capacity of 10 m3. As the septic tanks fill up, sewage is transported by sewage trucks to the sewage treatment plant in the city of Borodino (Appendix M). At the exit from the territory of the landfill, a control and disinfecting reinforced concrete bath (8,0 × 3,0 m, depth 0,3 m) is provided for disinfecting the wheels of dump trucks delivering solid waste. The bath is filled with 3% sodium hypochlorite. During the warm period, a contaminated disinfectant solution with a volume of 3 mXNUMX is collected in a barrel, as it accumulates, it is transported to a sewage treatment plant in the city of Borodino (Appendix M). In winter, salt is added to the disinfectant solution to prevent freezing of hypochlorite. Since the intensity of pollution in winter is lower than in summer, the solution in the disinfectant bath is not changed, periodically supplementing to the required level. At the end of winter, the disinfectant solution is drained into a barrel, from where, after settling, it is transported to sewage treatment plants.
