MBR组合工艺处理化工园区混合废水的中试研究

摘要

The wastwater treatment of Nantong chemical industrial park was processed by combination process of MBR,ozone oxidation and coagulation sedimentation.The carbon source adding method was also used.An experiment of the Nantong chemical industrial park wastewater treatment by combination process of MBR,ozone oxidation,coagulation sedimentation and adding carbon source was processed.The main indexes of effluent water reached the level 1-A of "the urban sewage treatment plant pollutant discharge standard ".The combination process has the advantages of less occupied area,high automation level,easy to operate,good and stable water quality.This process has a good application prospect in chemical wastewater treatment of the chemical industrial park.%通过采用MBR、臭氧氧化、混凝沉降以及补加碳源等组合工艺对南通化工园区的化工污水进行处理,出水总体指标达到了《城镇污水处理厂污染物排放标准》的一级A标准.该组合工艺具有占地面积小,自动化程度高,出水水质好且稳定等优点.在化工园区废水的处理中具有良好的应用前景.
