摘要
针对某化纤厂废水采用水解酸化、两级串联生物接触氧化为主,辅以两级混凝气浮的处理工艺。处理水量400m3/d,进水CODCr1200mg/L。废水处理后主要污染物CODCr、SS、NH3-N和TP的去除率分别为90%、81%、89%和70.3%,各项出水指标符合《污水综合排放标准》(GB 8978-1996)一级标准要求。
In response to a chemical fiber plant wastewater by hydrolytic acidification ,biological contact oxidation, two series, supplemented with two levels of coagulation air flotation process. Treatment of water of 400m3/d, CODcr1200mg / L inlet. Wastewater treatment of major pollutants CODcr, SS, NH3 -N and TP removal rates were 90%, 81%, 89%, 70.3%, the effluent indicators achieved the first level to discharge the standard of sewage synthesis discharges Standard＂ （GB8978 -1996）.
