Study on Effect of Anaerobic Biological Treatment on Biodegradability of Wastewater
The wastewater produced in the process of pesticide intermediates production has complex composition,high COD,and some wastewater contains substances that can easily lead to biochemical sludge poisoning.In the process of treating such wastewater,the biochemical tank is prone to abnormal situations such as COD failure to degrade below the standard value or sludge poisoning.In order to solve the above problems,a self-made biochemical wastewater treatment device was used to investigate the influence of anaerobic biological treatment process on improving the biodegradability of the produced wastewater during the production of pesticide intermediates in the company,and the influence of different anaerobic biological treatment conditions on improving the biodegradability of the wastewater.The experimental results show that the biodegradability of wastewater can be significantly improved by anaerobic biological treatment.The optimal conditions for anaerobic biological treatment are temperature:10～40℃,time:15～20 h,MLSS:30～40 mg/L,and BOD5/CODCr of wastewater can be increased by 32%by this method.
