改性硅藻土的多级 A／O 工艺除磷优化及尾水深度除磷
Optimization of Phosphorus Removal from Multistage A/O Process with Modified Diatomite and Advanced Treatment of Phosphorus Removal in Tail Water
摘要
Abstract
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.关键词
