采用物化和生化相结合的工艺处理盐化工废水
|
摘要
针对典型盐化工废水水质特征,物化处理主要采用混凝沉淀及吹脱去除硫化物及乙炔,生化处理采用水解酸化及曝气生物流化池去除NH4+-N及COD,运行结果表明,该组合工艺可以有效降低废水中主要污染物的含量,出水NH4+-N<10 mg/L、CODCr<50mg/L、BOD5<15 mg/L、SS<50 mg/L,出水水质优于《污水综合排放标准》(GB 8978-1996)一级标准,运行成本为2.26元/m3。
According to the characteristics of typical salt chemical engineering wastewater,Coagulating sedimentation and stripping were used as phy-chemical technology to remove sulphide and Acetylene. Hydrolytic acidification and aeration biological fluid tank were used as bio-chemical technology to remove NH4+-N and COD. The running results indicated that the effluent was superior to the primary standard of Integrated Wastewater Discharge Standard(GB 8978-1996),with NH4+-N<10 mg/L, CODCr<50 mg/L, BOD5<15 mg/L, SS<50 mg/L. The running cost was 2.26 yuan/m3.
