Description
Technical field
The present invention relates to technical field of sewage more particularly to a kind of just rain processing system and methods.
Background technique
Currently, not yet taking the pollution of cities and towns rainwash caused by separate system initial rainwater the control of effective system
Measure.City rainfall runoff is one of the main reason for causing receiving water body environmental degradation, and city rainfall runoff carries pollutant
Type is more and amount is big, seriously affects receiving water body water quality, and storm runoff washes away the emphasis that pollution is water environment management for the first time.
6-8mm rainfall is carried more than 60% pollutant before research finds rainfall, and preceding 10mm rainfall carries 80% pollutant.Initial stage
Rainwater pollution is more serious, but its wastewater mass concentration is higher, in different time, natural rainfall and different underlying surface pollutant
Mass concentration differs greatly.Show COD, TN, TP to SS with preferable related the result of study of correlation between pollutant
Property, wherein COD and SS related coefficient are up to 0.9 or more.
By construction investment limitation and there is no the actual conditions of first rain processing charging standard, and wastewater treatment in China facility is also
It is opposite to lack, it is also actively working to municipal sewage treatment at present, the initial rainwater and rainy season that are more than sewage treatment plant's scale are collaborated dirty
Water discharges after setting pot is handled mostly, less to pollutant removal, and only individually side starts to rainy season combined sewage
It is handled.Since processing intent, the difference of Effluent criteria also have very big difference, processing in broad sense includes treatment process
Dephosphorization, denitrogenation, SS, removal of organic matter etc., but since rainy season intercepting sewage is by time restriction, the number of days occurred in 1 year is not
It is more, if press municipal sewage treatment the process development, there are facility utilization rates it is too low, operational management is complicated the problems such as.So general next
It says, the processing of rainy season intercepting sewage is mainly based on physics, chemical method.
