| 摘 要： | 采用硫酸亚铁化学絮凝沉淀和臭氧氧化工艺处理电石渣浆废水的试验结果表明,通过化学絮凝沉淀,电石渣浆废水硫化物(S2-)由(900~1100)mg/l降为(2.0~3.6)mg/l,CODcr由(1900~2200)mg/l降为(150~200)mg/l,再经臭氧氧化后,废水CODcr总去除率为97%,硫化物总去除率可达到99.9%,使出水CODcr和硫化物达到一级排放标准。

| Abstract: | Using ferrous sulphate fluorine as the flocculating agent and ozonation, the results of experiment show that the sulphide (S 2-) reduced from (900～1100) mg/l to (2.0～3.6) mg/l, the COD_ CRreduced from (1900～2200) mg/l to (150～200) mg/l after chemical flocculation, the total removal rate of COD_ CRreached 97%, and sulphide reached 99.9% after ozonation, so that the discharge of waste water met the requirements. |
