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。

Abstract:
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).
