Description
Technical field
The utility model relates to field of environment protection, relates in particular to a kind of Sewage treatment systems that focuses on domestic sewage in rural areas by using.
Background technology
Along with the fast development of rural economy, the modern household electrical equipment such as washing machine and water-heater have been used in increasing rural area, and the washing machine larger household electrical appliance that are water consumptions, water-heater also so that the life in the countryside water consumption greatly increase.Yet the unprocessed just directly discharging of domestic sewage in rural areas by using is one of reason that causes the Rural Water Environment pollution, also is the important factor that causes lake eutrophication.2010, approximately 27,000,000,000 tons of Chinese villages and small towns quantity of wastewater effluent.For a long time, because improvement lacks of capital and Rural Water Environment is protected the thin of consciousness, the sanitary sewage of Rural areas is unprocessed with regard to directly discharging, becomes the major cause of rivers and lakes water quality decline.Carry out the research of technology for treating domestic sewage in rural area, explore the tupe that is fit to domestic sewage in rural areas by using, to promoting the construction of new socialist countryside, have urgent realistic meaning.In the arid area, be one of effective ways of implementing the sewage recycling utilization.
The utility model content
The technical problems to be solved in the utility model is: a kind of Sewage treatment systems that focuses on domestic sewage in rural areas by using is provided.
For the technical scheme that addresses the above problem employing is: rural domestic sewage treatment system comprises anaerobic digester, water entry, drainage channel, biogas pipe; Water entry one end is connected with anaerobic digester, and the other end is sewage inlet; Drainage channel one end is connected with anaerobic digester, and the other end is the outlet of water after purifying; Biogas Guan Yiduan is connected with the anaerobic digester top, and the other end is methane outlet.
Further be: be provided with mudpan on the drainage channel.
Further be: the downstream portion of the inherent water (flow) direction of mudpan is provided with filtering net.
Further be: rural domestic sewage treatment system comprises sludge refluxing apparatus, and sludge refluxing apparatus connects anaerobic digester and mudpan.
Further be: the biogas pipe is connected with tensimeter near an end of anaerobic digester.
The beneficial effects of the utility model are: utilize anaerobic biochemical to dispose of sewage in anaerobic digester.Anaerobic biochemical is exactly under anaerobic, by the acting in conjunction of multiple anaerobism or facultative microbe, and decomposing organic matter, and produce CH
4And CO
2The method is widely used in processing trade effluent at present, has applied widelyly, and energy consumption is low, and germicidal action is arranged, and mud is the advantage such as storage easily.By water entry each family sewage is focused in the anaerobic digester and to process; Water after will processing by drainage channel is used for field irrigation, saving water resource; To process the rear biogas that produces by the biogas pipe and deliver to each family utilization.This processing system is a continuously feeding, and the system of discharging, the ability of disposing of sewage are strong and cost is lower.
Description of drawings:
Fig. 1 is the rural domestic sewage treatment system structural representation;
Be labeled as among the figure: water entry 1, anaerobic digester 2, tensimeter 3, biogas pipe 4, drainage channel 5, mudpan 6, filtering net 7, sludge refluxing apparatus 8, sludge pump 9.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
For a kind of Sewage treatment systems that focuses on domestic sewage in rural areas by using is provided, rural domestic sewage treatment system comprises anaerobic digester 2, water entry 1, drainage channel 5, biogas pipe 4; Water entry 1 one ends are connected with anaerobic digester 2, and the other end is sewage inlet; Drainage channel 5 one ends are connected with anaerobic digester 2, and the other end is the outlet of water after purifying; Biogas pipe 4 one ends are connected with anaerobic digester 2 tops, and the other end is methane outlet.Dispose of sewage at the anaerobic digester 2 interior anaerobic biochemicals that utilize.Anaerobic biochemical is exactly under anaerobic, by the acting in conjunction of multiple anaerobism or facultative microbe, and decomposing organic matter, and produce CH
4And CO
2The method is widely used in processing trade effluent at present, has applied widelyly, and energy consumption is low, and germicidal action is arranged, and mud is the advantage such as storage easily.By water entry 1 each family sewage is focused on anaerobic digester 2 interior processing; Water after will processing by drainage channel 5 is used for field irrigation, saving water resource; To process the rear biogas that produces by biogas pipe 4 and deliver to each family utilization.This processing system is a continuously feeding, and the system of discharging, the ability of disposing of sewage are strong and cost is lower.Anaerobic digester 2 is identical with anaerobic digester 2 structures of the processing trade effluent of prior art.Water entry 1 and drainage channel 5 can all be pipelines; Can partly be pipeline near anaerobic digester 2 and peasant family also, rest part be channel, channel relative duct size easy to clean, and cost is low.This rural domestic sewage treatment system preferably is arranged at lower position, makes sewage can rely on self gravitation to flow to anaerobic digester, and the water after the processing can extract to eminence by water pump and flow to the farmland.
Still may also have mud in the water after the processing, in order to process the mud in the water, avoid drainage channel 5 to stop up, and avoid mud to discharge, be provided with mudpan 6 on the drainage channel 5.Mudpan 6 volumes are large, and water static through after a while in mudpan 6 can make that sludge settling is to mudpan 6 bottoms in the water, and the water of discharging after the precipitation cleans more.
In order further to make the water cleaning of discharge, the downstream portion of mudpan 6 inherent water (flow) directions is provided with filtering net 7.Filter by filtering net 7, the water of discharge is cleaned more.
In order to make sludge treatment more thorough, rural domestic sewage treatment system comprises sludge refluxing apparatus 8, and sludge refluxing apparatus 8 connects anaerobic digester 2 and mudpan 6.Mud is got back in the anaerobic digester 2 by sludge refluxing apparatus 8 and is processed.Sludge refluxing apparatus 8 comprises the pipeline that connects anaerobic digester 2 and mudpan 6, is provided with the sludge pump 9 that makes mud flow to anaerobic digester 2 from mudpan 6 at this pipeline.
For the ease of monitoring at any time the pond internal pressure, and avoid fermentation vat because bearing the high pressure danger of blasting, close anaerobic digester 2 ends of biogas pipe 4 are connected with tensimeter 3.The staff can understand anaerobic digester 2 internal pressures by observing tensimeter 3 at any time, is convenient to take measures to control anaerobic digester 2 internal pressures.
