Ground, underground water pollution is easily caused, and needs periodically harvesting processing growing plants, nitrogen phosphorus ligands effect otherwise can be caused to decline,
Soil occurs purification function degeneration because of organic matter accumulation.China " 13 " planning, which proposes, " pushes forward rural residence ring comprehensively
The construction object of border regulation, increasing countryside sewage treating ".Therefore, the technology of sustainable, the easy to control nitrogen and phosphorous nutrient of development environment
It is most important." around Urban-rural Development integration, going deep into Promoting The Construction of New Countryside " weight proposed according to China " 13 " planning
Big historic task, and the construction object of " pushing forward Rural Human Settlements regulation comprehensively, increase countryside sewage treating ", based on current agriculture
Village's sanitary sewage disposal technology --- septic tank, stabilization pond, the denitrogenation dephosphorizing present in artificial swamp are difficult, soil organism accumulation
With hardened, floor space it is big, recover difficult and the defects of easily cause groundwater environment pollution, devise and a kind of be applied to processing
The integrated form integrated treatment unit of rural scattered domestic sewage, to adapt to the vast domestic sewage in rural areas decentralized processing in China
Technical requirements.Rural Water Environment problem is serious at present, lacks targetedly advanced and applicable sewage disposal technology.Rural area is dirty at present
Method for treating water has：Septic tank, stabilization pond, artificial swamp etc..These technologies are undesirable for the removal efficiency of nitrogen phosphorus, account for simultaneously
Ground area is big, and stabilization pond also has serious bed mud mud problem.
In summary, the problem of prior art is present be：At present treatment method for rural sewage exist removal efficiency it is undesirable,
Particularly nitrogen phosphorus ligands are poor, while floor space is big, there is serious bed mud mud.
The content of the invention
The problem of existing for prior art, the invention provides a kind of integrated form integral life sewage processing method.
The present invention is achieved in that a kind of integrated form integral life sewage processing method, the integrated form integration
Domestic sewage processing method comprises the following steps：
Step 1, sanitary sewage separation of solid and liquid, bulky grain floating object and sediment separation, are removed organic in sanitary sewage
Pollutant；
Step 2, the processing of sanitary sewage two-stage anaerobic, ventilation soil tank purify sewage using the effect of soil and microorganism；
Biological nitration/denitrifying microorganism environment is built, removes the ammonia nitrogen in sanitary sewage；Iron filings are laid in filler through corrosiveness to turn
It is changed into Fe3+, with PO4 3-Reaction generation precipitation FePO4, remove the phosphorus in sanitary sewage；Ventilation soil tank handle standard discharge or under
Ooze.
Further, the soil module of the gas permeability soil tank is mixed by pale red earth and sawdust, and loadings are
0.3m3, zeolite filler loadings are 0.5m3, iron filings loadings are 0.03m3；Soil module presses dry weight ratio by pale red earth and sawdust
85:15 are mixed, wherein pale red earth uses the preceding particle that need to be broken for 2~3mm of particle diameter.
Another object of the present invention is to provide a kind of integrated form of the integrated form integral life sewage processing method
Integral domestic sewage treatment device, the integrated form integral domestic sewage treatment device include：Preparation filter chamber, one-level are detested
