针对豆制品生产工艺废水水质特征,采用MIC+A2/O+深度处理工艺处理豆制品废水。结果表明,该工艺处理效果稳定可靠。废水COD由6 000 mg/L下降到300 mg/L左右,出水水质达到污水排入城镇下水道水质标准(CJ343-2010)中B等级标准,同时,产生的沼气可回收利用,具有较好的经济效益和环境效益。
According to the soya bean process wastewater characteristics,the MIC-A2/O-advanced treatment method was used for processing wastewater treatment.The operation of MIC-A2/O-advanced treatment showed that the process was steady and reliable.The result showed that COD concentration was reduced from 6 000 mg/L to 300 mg/L and the treated water can meet the requirement of the wastewater quality standards for discharge to municipal sewers(CJ343-2010)part B emission standard.At the same time,marsh gas produced can be reclaimed,which can bring good economic and environmental benefits.
