摘要
采用预处理—厌氧水解一二段接触氧化工艺处理阿维菌素废水,在厌氧段停留时间为10h,好氧段停留时间为6h条件下,厌氧好氧段COD总去除率达91%,可使综合废水由CODcr=18569mg/l,BOD5=4718mg/l降到CODcr=557mg/l,BOD5=259mg/l,达到该地区污水处理厂要求排放标准,并分析了废水处理中的影响和抑制因素,本工艺污泥量少,具有良好的抗冲击负荷能力,尤其是废水资源回收和利用,具有良好的经济效益。
This paper deals with the wastewater treatment process of pretreatment anaerobic hydrolysis two statge bio contact oxidation.Under the water retention time is 10h at anaerobic stage and 6h at oxidation stage,the abamectin wastewater with COD cr =18569mg/l and BOD 5=4718mg/l can be reduced to COD cr =557mg/l,BOD 5=259mg/l and meet the municipal wastewater discharge standard.Its characteristics are the wastewater resource reclamation and better environmental economical benefits.
