| Abstract: | In order to solve the problem that the quality of the effluent water from coking wastewater treatment process can′t meet the discharge standard,the feasibility of hydrolysis acidification-A2/O-MBR-BAC combined process treating coking wastewater was studied through the test.The results showed that,when the mass concentration of NH3-N in the influent water was about 88 mg/L,the mass concentration of NH3-N in the effluent water kept a stable value of 3 mg/L,and the removal rate of NH3-N reached 96%.Meanwhile,when the influent CODCr mass concentration was about 970 mg/L,the removal rate of CODCr could reach 90%,the effluent water quality met the specification for grade 1 in GB 8978—1996 Integrated Wastewater Discharge Standard.It could be seen that,using the said technology to treat coking wastewater could get a satisfying effect. |
