Description
Technical field
The present invention relates to a kind of soil filtration bed body technology method of processing domestic sewage in rural areas by using, particularly relate to the soil filtration bed body technology method of processing domestic sewage in rural areas by using under a kind of full season condition.
Background technology
Present national rural area is annual to produce about 8,000,000,000 tons of sanitary sewage, and 96 ° village does not have discharge conduit and Sewage treatment systems.Undressed sanitary sewage discharges wantonly, severe contamination the ecotope in rural area, directly threaten the Economic development in the vast farmers masses' healthy and rural area.Undressed sanitary sewage flows automatically to physical features and is in the surface water bodies such as low-lying river, lake and pond all kinds of water sources of severe contamination.Simultaneously, sanitary sewage is the source of disease propagation diffusion, causes easily the generation of some areas transmissible disease, endemy and zoonosis and popular.Generally speaking, China's domestic sewage in rural areas by using have disperse wide, the source is many, it is fast to increase, complicated component, water quality and water yield variation feature greatly.
China's rural domestic sewage treatment still is in the starting stage, in view of the relatively poor and lower present situation of level of management of Rural areas economic situation, need badly and seek a kind of capital construction and running cost is low, the management simple, treatment effect is good, Ecosystem Service is good decentralized wastewater ecological treatment method.The underground sewage percolating system is a kind of small-sized sewage natural purification system.The technological process that underground sewage percolating is processed is: at first, sewage controlledly batched to have certain structure, has in the soil layer of good diffusion performance; Then, sewage is made four-dimensional diffusion motion towards periphery under soil capillary infiltration and soil filtration effect; At last, sewage is purified under the combined action of physical/chemical/plant/microorganism, water outlet reuse after header is collected.Subsurface wastewater infiltration system have process that effluent quality is good, less investment, management are simple, device is positioned at and does not undergroundly destroy view and the advantage such as be destitute of smell, and have become the sewage water treatment method of domestic and international pay attention to day by day.
Through the tackling key problem research of recent two decades, underground sewage percolating technique has obtained breakthrough progress at aspects such as structure design, process optimization, operating parameter adjustment, and the subsurface infiltration technology has become the one preferred technique pattern of processing rural decentralized wastewater.Yet, at China's high latitude area, being subjected to the low impact of winter temperature, matrix bed body diafiltration district microorganism active sharply descends the subsurface wastewater infiltration system poor processing effect.
Summary of the invention
The object of the present invention is to provide the soil filtration bed body technology method of processing domestic sewage in rural areas by using under a kind of full season condition, after the method is implemented under the full season condition, can promote diafiltration district microorganism active, improve the system applies universality, effectively solve subsurface wastewater infiltration system winter operation problem.
The objective of the invention is to be achieved through the following technical solutions:
Process the soil filtration bed body technology method of domestic sewage in rural areas by using under the full season condition, said method comprising the steps of: tamp with clay around the diafiltration bed body, lay one deck density polyethylene film with high around the bed body, the header that sidewall evenly punches is in advance laid in diafiltration bed body bottom, lay one deck gravel around the header, above frozen soil layer, lay one deck artificial soil, the artificial soil horizon lays to finish and spread water infiltration 24 hours, the artificial soil horizon lays the anaerobism groove in the top, section is trapezoidal, the inner filling of anaerobism groove expired gravel, sidewall is laid in advance the evenly water spraying pipe of punching directly over the anaerobism groove, and is consistent with anaerobism groove vergence direction, lays one deck cultivated soil above the artificial soil horizon, earth's surface plantation herbaceous plant, domestic sewage in rural areas by using enters subsurface infiltration bed body under the unpowered condition of water spraying pipe, process water outlet and collected by header, analyzes Inlet and outlet water water quality, in the sampling of the diafiltration bed body different vertical degree of depth, analyze microorganism active and get final product.
Process the soil filtration bed body technology method of domestic sewage in rural areas by using under the described full season condition, 1.5 meters to 2.0 meters of the described diafiltration bed body degree of depth, 0.8 meter to 1.0 meters of artificial soil layer thickness, cultivated soil is laid 0.55 meter to 0.75 meter of the degree of depth.
Process the soil filtration bed body technology method of domestic sewage in rural areas by using under the described full season condition, described header is laid 3 ° to 5 ° of angles, lays 4 millimeters to 8 millimeters of grain size of gravels around the header.
Process the soil filtration bed body technology method of domestic sewage in rural areas by using under the described full season condition, 3 ° to 5 ° of described anaerobism groove ply angles, inner 5 millimeters to 8 millimeters of the grain size of gravels of filling of anaerobism groove.
Process the soil filtration bed body technology method of domestic sewage in rural areas by using under the described full season condition, described water spraying pipe is laid 3 ° to 5 ° of angles.
Advantage of the present invention and effect are:
1. be used for the soil filtration technique that rural decentralized wastewater processes and fill medium take cultivated soil and gravel for main the processing, less investment, management are simply, device is positioned at the underground view that do not destroy, and are destitute of smell.
2. be used for the soil filtration technique that rural decentralized wastewater is processed under the full season condition, can according to region characteristic, adjust flexibly water spraying pipe and the bed body degree of depth.
3. affected by winter temperature, traditional subsurface infiltration technique is difficult to adapt at the northern China high latitude area.Adopt above-mentioned soil filtration bed method of design, water spraying pipe and header all are positioned at below the frozen soil layer, guarantee that microorganism active and treatment effect are not subjected to seasonal effect, and effluent quality satisfies view surface water quality standard.
