摘要
根据农村生活污水的特点,采用生物接触氧化与人工湿地相结合的技术,设计了农村生活污水处理工艺,探讨了不同负荷对该工艺处理效果的影响。工程运行实践表明,该工艺对农村生活污水具有良好的处理效果,其中CODCr的平均去除率达到72.9%,对总氮、总磷的平均去除率分别为86.6%、89.1%,出水水质能稳定达到国家一级排放标准。
According to the characteristics of rural domestic sewage,the treatment system was designed for treating rural domestic sewage with combined technology of biological contact oxidization and constructed wetland,and effect of different load on efficiency of combined technology was also discussed. The average removal rate of CODCr,TN and TP were 72.9%,86.6% and 89.1% respectively,which meet requirements of first grade discharging standard.
