【摘要】 研究采用混凝—CASS法处理开心果加工废水。试验结果表明,混凝处理中混凝剂PAC的处理效果优于PFS,其最佳pH范围为7~10,最佳投药量为175mg/L。以PAC为混凝剂处理后的废水采用CASS法进行生化处理,在曝气12h的条件下,CODCr和BOD5去除率分别为94.4%和96.1%,最终出水达到污水综合排放标准的一级标准。更多还原

【Abstract】 This paper introduced the treatment of pistachio nut wastewater by coagulation-CASS. The experiment result showed that the PAC’s coagulator result was better than PFS. The best pH range was 7～10. After coagulated, the wastewater was treated by CASS process. In this process, the removal rate of COD_Cr was 94.4% and the removal rate of BOD₅ was 96.1%.更多还原
