市政污水处理中膜处理技术的应用

Application of Membrane Treatment Technology in Municipal Wastewater Treatment

随着科技的不断进步,越来越多的技术被广泛用于市政污水处理,如BAF、A2/O法等,此类污水处理法往往需要掺加一定量化学药剂才能去除污水内细菌、有毒物质,同时极易产生二次污染问题。如何实现低能耗、高效率地完成污水处理工作显得尤为重要。目前在纯水分离、净化饮用水等方面膜技术得到了广泛应用,相比其他处理法,超滤工艺的特点可归结为低成本、极易制备,且性能良好。

With the continuous progress of science and technology,more and more technologies are widely used in municipal wastewater treatment,such as BAF,A2/O,etc.Such wastewater treatment methods often require the addition of a certain amount of chemical agents to remove bacteria and toxic substances from the wastewater,which is easily lead to secondary pollution problem.How to achieve the completion of sewage treatment work in a low-energy and high-efficiency way is particularly important.At present,membrane technology has been widely used in pure water separation,purification of drinking water,etc.Compared with other treatment methods,the characteristics of ultrafiltration process can be attributed to low cost,easy preparation and good performance.
