摘要
研究了利用不同混凝剂处理壮骨粉生产废水的最佳工艺条件。结果表明 ,选用聚合硫酸铁铝 ( PAFS)比较适宜 ,其最佳投加量为 2 0 0 mg/L ,适宜 p H值为 7～ 8,此时COD的去除率为 72 .1 %。上清液再经双层滤料柱过滤 ,COD和 SS的总去除率可分别达到 94.9%和 91 .8% ,出水 COD、SS和 p
The study examined the effects of different coagulants on treating grease wastewater and the optimal technology conditions.The results are as following:PAFS is the best coagulant,the dosage of which is 200 mg/L,the pH value of the wastewater was 7~8 and the COD removal rate reaches 72.1%.When the liquor supernatant passes two layer filter column,the effluent COD and SS removal rates reach 94.9% and 91.8%.The effluent COD,SS and pH reach effluent standard.
