Research on Drainage Quality Index and Management Limit of Petrochemical Industrial Zone Enterprises
In view of the problem of inconsistent drainage limits of enterprises in petrochemical industrial zone,BOD5,COD,NH3-N,TN,TP and other indicators of enterprises in industrial zone drainage were systematically investigated and analyzed.Through the analysis,it was found that the BOD5,COD density significantly reduced after pretreatment,and NH3-N,TN,TP treatment effect is relatively poor,resulting in the decrease of B/C value in the terminal wastewater treatment plant,affected the wastewater biological sex,increased the wastewater treatment cost and difficulty of the late.In view of this situation,the tolerable and PIPE limits of THE conventional indicators for enterprises in industrial zones are put forward,which will effectively save the cost of water treatment and improve the centralized treatment capacity of wastewater.
