低成本废水生态处理组合工艺在农家乐废水治理中的应用

以一典型农家乐生活废水为处理对象,采用以低成本废水生态处理技术为主体的组合处理工艺,研究了该工艺对农家乐废水的处理效果。结果表明:该废水处理系统稳定运行时对COD和NH4+-N的平均去除率分别达80%和50%以上,出水ρ(TP)一直保持在2.0 mg/L以下。该废水处理技术不仅简单易行、效果好,而且建造及运行成本低,在农村分散型废水治理方面具有良好的推广应用价值。

A CASE STUDY ON DOMESTIC WASTE WATER TREATMENT BY USING LOW-COST ECOLOGICAL COMBINATION PROCESS

Using low cost ecological combination process to treat the domestic waste water from a typical farmhouse restaurant,it was studied the removal effectiveness of the main pollutants.The results showed that the newly developed low cost waste water treatment system could have a good effect of removing COD,NH+4-N and TP when the system was in stable operation.The average removal rate of COD and NH+4-N was over 80% and 50% respectively,TP was below 2.0 mg/L.It is believed that the low cost ecological combination process will be valuable to treat the domestic waste water from scattered farmhouses,because of its simplicity,effectiveness and low cost.
