硅藻土经过酸洗提纯,加入聚合氯化铝、氯化铁进行表面结构改性.用改性硅藻土处理多级 A/O 工艺二沉池出水,研究了不同投加量、停留时间、搅拌转速对尾水中磷去除的影响.试验结果表明:在投加量为500 mg·L-1,停留时间为1.5 h,机械搅拌转速为12 r·min-1时,出水总磷小于0.5mg·L-1,达到了一级 A 的排放标准.

After acid purification,the diatomite was modified with the mixture of PAC and ferric chloride by surface structure method.The effects of modified diatomite dosage,retention time,and the mechanical stirring speed on the phosphorus removal from tail water were investigated using the modified diatomite to treat the effluent after multistage A/O process.The results showed that the optimal dosage was 500 mg·L-1 ,the hydraulic retention time was 1.5 h,and the optimum mechanical stirring speed was 12 r·min-1 .In this case,the total phosphorus in the effluent was less than 0.5 mg·L-1 ,and reached the emission standard of A.
