啤酒酵母在农村污水处理中的应用探索

Exploration of the Application of Beer Yeast in Rural Sewage Treatment

我国是农业大国,广袤的农村近年来承受着重金属转移污染的潜在威胁。国内外研究均表明,啤酒酵母生物吸附法对废水中的重金属具有良好的吸附效果,且操作简单、成本低,不易引起二次污染,尤其在处理低浓度重金属废水时,比传统方法更具优势。如果其能与农村污水综合整治及稻壳、秸秆等资源再利用环境治理工程同步整合实施,能够事半功倍,达到更好的污水治理成效。

China is a large agricultural country.In recent years,the vast rural areas are under the potential threat of heavy metal transfer pollution.Research at home and abroad have shown that the brewer’s yeast biosorption method has a good effect on the adsorption of heavy metals in wastewater,and is simple in operation,low in cost,and not easy to cause secondary pollution,especially in the treatment of low concentration heavy metal wastewater,it has advantages over traditional methods.If it can be integrated with environmental treatment projects such as rural sewage comprehensive treatment,rice husk,straw and other resources reuse,it can achieve twice the result with half the effort and achieve better sewage treatment results.
