Description
Technical field
The present invention relates to agricultural environment field, is more particularly to a kind of domestic sewage in rural areas ecological treatment method, also simultaneously
It is related to a kind of system of domestic sewage in rural areas ecological management, be particularly suitable for use in subtropical zone rural area natural village, gathering ground or rill
Domain, daily life sewage is handled using village corner vacant land (wasteland), realizes the water correction of rural area small pond, streamlet.
Background technology
Improved as life in the countryside is horizontal and inproving living environment, between rural health, the living facilities such as shower house, washing machine
Popularization and application, the random discharge of domestic sewage in rural areas causes COD in water body such as the pond in rural area, irrigation canals and ditches, streams, ammonia nitrogen, total
Nitrogen, total phosphor contaminant are exceeded serious, cause Rural Water Environment problem outstanding day by day.Domestic sewage of villages and small towns, scattered breeding wastewater and
Processing of farm products blowdown turns into important agricultural environment pollution source.According to Chinese Ministry of Environmental Protection's survey data, by Chinese villages and small towns resident people
Equal sanitary sewage discharges 90 liters/man day, in sanitary sewage COD, total nitrogen and total phosphorus content be respectively 205mg/L, 50mg/L and
5.5mg/L is counted, and there are 6.4 hundred million villages and small towns populations in current China, and the COD discharged every year, total nitrogen and total phosphorus are up to 431.0,105.1 respectively
With 11.6 ten thousand tons.Because Rural Water Environment pollution source is complicated, distribution is wide, difficulty of governance is big, compared with municipal sewage treatment,
Centralized collection is difficult to, unsuitable (peasant household is sparsely populated, and pipe network collects the cost of sewage too using the tupe excessively concentrated
It is high).Rural sewage treatment pattern and technology generally can be divided into focus on, decentralized processing and treatment in situ pattern.(1) at concentration
Reason pattern：The pattern of focusing on is suitable for the villages and small towns having a large population, the density of population is big and sewage yield is big；Collected using pipe network dirty
Water, sewage treatment plant is established, sewage can qualified discharge or reuse after processing.The active sludge of sewage disposal technology of generally use
Method and the methods of SBR.(2) decentralized processing pattern：The major technique of domestic and international separated practices sanitary sewage has wetland variation system
System, High-Rate Algae Pond technology, artificial wet land treating system and anaerobic methane pool technology etc..(3) traditional sewage disposal system in situ
System (septic tank) go to denitrogenate, effect is poor in terms of phosphorus compound and pathogenic organisms, be only used as pre-processing device further to control
