摘要
焦化废水含有毒物质多,生物降解性能差,对环境危害大。实验采用厌氧水解(酸化)-好氧(高效复合菌+活性污泥)工艺处理焦化废水,进水COD、BOD5浓度分别为:698.13mg/l、232.0 mg/l,经12h厌氧水解、18h好氧曝气后出水COD、BOD5浓度分别为136.93 mg/l、39.3 mg/l,NH3-N的去除率为68.37%。出水COD、BOD5满足《污水综合排放标准》(GB8978-96)中的排放要求。
Coking wastewater was a kind of organic wastewater containing large amounts of toxic and harmful pollutants, It would result in serious pollution of the environment, and directly threatening human health. The paper studies on Coking wastewater treatment by anaerobic hydrolysis and SBR process, treatment,When the COD and BOD concentrations of influent were 698.13 and 232.0 mg/L, Their concentrations of the final effluent were 136.93 mg/l,39.3 mg/l, respectively. NH3 - N removals were 68.37%. the effluent quality reached the first- class standard specified in“Integrated Wastewater Discharge Standard”（ GB 8978 -1996） .
