Description
Technical field
The present invention relates to a kind of highway sewage P-RAD treatment process and methods, belong to technical field of sewage.
Background technique
The sanitary sewages water such as Expressway Service, charge station, management station is small, the water of website dispersion and different periods
Matter, water are different.Sewage has the characteristics that ammonia nitrogen and phosphorus content height, content of organics are relatively low, according to traditional micro- life
Object processing, because to lack Nitrogen/Phosphorus Removal limited for organic carbon source, effluent quality is difficult to up to standard, especially realizes high-level emission request
As " Beijing's urban wastewater treatment firm pollutant emission standard " (DB11/307-2013) A emission limit will be more difficult.It is conventional
Going nitrogen and phosphorus method in water removal is usually to add organic carbon source and chemical dephosphorization medicament, therefore cost of sewage disposal is higher, operation
Complex management.According to physical method and chemical method, while there is also complicated for operation, processing cost is higher, generates secondary pollution
The problems such as, and extensive use is hardly resulted in actual domestic wastewater processing.
Summary of the invention
In order to solve the deficiency of the sanitary sewage disposals technology such as Expressway Service, charge station, management station, the present invention is mentioned
For a kind of highway sewage P-RAD treatment process and method.
A kind of highway sewage P-RAD treatment process and method, contain following steps: using fine screen mesh except in decontaminated water
