The country sewage comprehensive utilization treatment system that the present invention proposes is a distributed processing system, is all kinds of country sewages such as natural pond liquid and sewage dynamically to be mixed focus on, and the while therefrom collects one of high efficient energy sources and overlaps water treatment energy regeneration system.
Domestic sewage in rural areas by using is mainly from the lavatory flushing water of farmers', kitchen washing water, shower draining, excrement of animals water etc.Natural pond liquid be organic substance in anaerobic environment, under the condition of certain temperature, humidity, potential of hydrogen,, produce remainder water solution after the methane through the microbial fermentation effect.Still also have a large amount of pollutents in the liquid of natural pond, and Pollutant levels are high, intractability is big.Yet the water yield of natural pond liquid is often smaller, and is rich in a large amount of biological inoculums.
After natural pond liquid, all kinds of country sewages of sewage dynamically mix; Getting into the bio anaerobic pond together handles; When the sewage that the water yield is bigger has diluted in the liquid of natural pond organic concentration; Utilize biological inoculum abundant in the liquid of natural pond to carry out degradation treatment, improved processing efficiency and the speed disposed of sewage in the bio anaerobic pond greatly.Composite waste after handle in the bio anaerobic pond is from flowing into biological wetland.Waterplant in the wetland has crown_interception to the SS in the sewage.And around root system of plant, at a distance and more at a distance then can form aerobic, anoxic, anaerobic environment to some extent, remove pollutents such as COD in the sewage, ammonia nitrogen effectively.Sewage after the processing all can reach direct emission standards, can directly be disposed to the river course or be used for the field to irrigate.
Can produce a large amount of biogas in the methane-generating pit, and the bio anaerobic pond also a spot of biogas can occur, the Chi Ding in two ponds is provided with the collecting methane pipeline respectively.Yet, contain in the biogas by 55%～70% methane, 25%～40% carbonic acid gas and a spot of nitrogen sulfide and hydrogen sulfide, need purify, with supplying the daily use of resident behind the biogas process marsh gas purifying device of collecting.The clearance of native system COD, BOD, TS can reach 85%～90%, and technology is simple, invests lowlyer, can effectively solve a rural environment regulation difficult problem, and the biogas engineering construction is also had important meaning.
This system has following advantage:
1. improve the processing efficiency of country sewage, reduced country sewage processing cost and working cost;
2. simplification technology, simple in structure, be easy to make, easy care, failure rate is low, is convenient to operation;
3. the biogas that produces can be used for resident living with ability, marsh gas power generation, and methane boiler and insulation etc., the natural pond slag in the methane-generating pit can be used as fertilizer, and is respond well, is convenient to transportation, stores, uses.
