摘要
采用厌氧池/人工湿地/生物塘的组合工艺对某奶牛养殖场废水进行处理。结果表明,该系统的处理效果良好,SS和COD主要在厌氧池和人工湿地中被去除,NH4+-N、TN和TP主要在人工湿地和生物塘中被去除,整个系统对SS、COD、NH4+-N、TN和TP的平均去除率分别为91%、74%、72%、62%和85%,出水水质可达到《农田灌溉水质标准》(GB5084—2005)的要求。该系统的成本低廉且易于运行维护,具有良好的经济效益与环境效益。
The combined system of anaerobic tank/constructed wetland/biological pong was applied to treat the cows farm wastewater. The results show that the treatment effect of the system is favora- ble, SS and COD are removed mainly in anaerobic tank and constructed wetland, while NH4^+ -N, TN and TP are removed mainly in constructed wetland and biological pond. The average removal rates of SS, COD, NH4^+ -N, TN and TP in the whole system are 91% , 74% , 72% , 62% and 85% respectively. The effluent quality can reach the requirement of Standards for Irrigation Water Quality (GB 5084 - 2005 ). The system is low in cost and easy to be operated and maintained, and it has better economical arid environmental benefits.
