Abstract:

The plant-produced wastewater of a bioengineering plant has been treated by anaerobic process(circulating granula sludge reactor,i.e. MQIC reactor),ammonia oxidation process and flocculation-sedimentation tank, whose treatment capacity is 10 000 m³/d. The removing rates of COD,NH₄⁺-N and TN are 97%,98% and 90%, respectively. The operation is stable and the effluent water quality could meet the acceptable requirements specified by the industrial park. In addition,the statement on the start-up and debugging for MQIC reactor and AMOXP are made. The practice proves that this process has remarkable effect on the treatment of organic wastewater containing highly concentrated ammonia nitrogen.

Key words: organic wastewater containing high ammonia nitrogen, MQIC reactor, ammonia oxidation process

摘要：

介绍了某生物工程厂采用厌氧工艺(循环式颗粒污泥反应器,即MQIC反应器)、氨氧化工艺和絮凝沉淀池处理厂区生产废水,处理量为10 000 m³/d,该工艺系统对原水中COD、NH₄⁺-N、TN的去除率分别可达97%、98%、90%,运行稳定,整个工艺处理出水水质可达到园区接管要求。同时,对厂区MQIC反应器和氨氧化工艺的启动调试进行了阐述,实践证明该工艺系统对处理高氨氮有机废水效果显著。
