表面流人工湿地用于农家乐旅游设施污水处理的试验研究

Experiment of Surface Flow in Constructed Wetland for Farmer Household Tourism Wastewater

讨论了农家乐旅游设施污水处理中的制约因素,提出了采用人工湿地处理工艺解决农家乐污水排放问题的思路,并进行了试验研究。结果表明:人工芦苇湿地对CODCr、BOD5、氨氮及SS的去除率分别达47.97%、51.35%、76.19%、30.77%以上,人工芦苇湿地末端的出水水质可以稳定达到GB8978—1996《污水综合排放标准》界定的一级标准。

he restriction factors are discussed for the farmer household tourism wastewater purification,and then the surface flow in constructed wetland process is presented in order to purify the farmer household tourism wastewater.The results of the present study showed that the removal rates of CODCr,BOD5,NH3-H,SS were over 47.97%,51.35%,76.19%,30.77%,respectively,in the surface flow in the constructed wetland system.The effluent of the surface flow in the constructed wetland system was able to meet the first class of the Integrated Wastewater Discharge Standard(GB 8978-1996).
