摘　　要：采用以人工湿地为主体的工艺处理小型养殖场产生的废水,先经稀释、混合调节对高浓度废水进行预处理,之后依次进入简易厌氧池、四级人工湿地和生物塘工序。实际运行结果表明:该工艺处理效果好,运行稳定,耐冲击负荷能力强,费用低廉,SS、COD、NH4+-N、TP去除率分别达到91%、89%、62%和88%,出水可达再生水回用于农业用水选择性标准。The wastewater from small scale animal farm was in＇st diluted and mixed, then followed by simple anaerobic tank, four stages constructed wetland and biological pond. Results show that the process not only is effective and stable operation, but also has a strong impact resistant capacity and a low cost. The average removal rates of SS, COD, NI4^＋ -N and TP are 91%, 89%, 62% and 88% respectively. The effluent quality can meet the requirements of standards of reclaimed water quality for agricultural use.
