摘要
采用"水解酸化—接触氧化—曝气生物滤池"工艺处理由印染废水和生活污水组成的工业园废水,其CODCr从800 mg/L左右降到60 mg/L以下,BOD5从250 mg/L左右降到20 mg/L以下,去除率均达到了92%以上,出水水质达到《城镇污水处理厂污染物排放标准》(GB 18918—2002)中一级标准的B标准。
The wastewater in an industrial park can be treated by hydrolytic acidification-contacting oxidation- biological aerated filter（BAF） process. The wastewater mainly consists of printing ＆ dyeing wastewater and domestic sewage. Through the operation of this process ,the CODCr of effluent can fall from about 800 mg/L of influent to below 60 mg/L, and BOD5 of effluent can fall from about 250 mg/L of influent to below 20 mg/L. Both of the removal rates can reach more than 92%. The effluent water quality reaches Standard B of the first order in Pollutants Emission Standard of Urban Wastewater Treatment Plants （GB 18918--2002）.
