摘要
将同时反硝化产甲烷作为主体工艺处理某奶牛养殖场废水,介绍了工艺流程及设计参数,并对反应器的启动和运行过程进行分析和总结。实践表明,厌氧反应器与硝化工艺联用,省去传统反硝化工序,在UASB反应器COD负荷为2.0 kg/(m^3·d)、NO_3^--N负荷为0.08~0.12 kg/(m^3·d)时,同时反硝化产甲烷过程的COD及TN去除率均能达到90%以上,系统运行稳定。辅以氧化塘-化学消毒脱色-活性炭过滤等深度处理工艺,废水回用率75%,外排废水满足DB 32/1072-2007排放要求。
Simultaneous denitrification/methanogenesis process was used as the main process for one dairy farm wastewater treatment project. Technological process and designing data were introduced in detail, and the start-up and operation processes of the reactor were analyzed and summarized. Practice and results showed that the combined anaerobic and nitrification process eliminated the traditional denitrification process. The simultaneous denitrification and methanogenesis process was running stable when UASB reactor reached COD load to 2.0 kg/（m^3·d） and nitrate load to 0.08～0.12 kg/（m^3·d）. COD and total nitrogen removal rates could reach more than 90%. Combined with oxidation pond/chemical disinfection decolorization/activated carbon filtration depth treatment process, wastewater reuse rate reached 75% and the effluent met the DB 32/1072-2007 discharge standard.
