| Abstract: | Second class of the Integrated Wastewater Discharge Standard(GB8978-1996) was employed by some projects constructed before 1999.It is unable to meet the current national sanitary standard of first B class of Municipal Wastewater Treatment Plant discharge standards(GB 18918-2002) at nitrogen and phosphorus.Water quality parameters of inflow have characteristics of low C/N.Sewage treatment system has been reconstruction for up-to-standard.Bioselection pool,anaerobic tank and Anoxic tank have been construction... |
