微滤膜与活性炭联用工艺去除富营养化水源水中藻类

湖泊及水库含藻水问题带有一定的普遍性,处理技术复杂,难度较大。因此,除藻技术的提高和发展显得越来越紧迫。膜处理技术在给水中的应用是水处理技术的重大突破,正逐渐成为21世纪水处理技术中最有发展前途的技术。本文以继承和吸收成熟技术,并将其工程化,以便及时解决具体问题为原则,根据国内外最新水质标准要求,提出了微滤膜与活性炭联用的除藻新上艺,并对除藻工艺方案确定原则、研究内容和目标,以及除藻工艺方案设计进行了说细分析说明。本文认为微滤膜技术在我国供水行业推广已经具备了较好的条件,在不断积累经验的基础上可以达到大规模工程应用。应用微滤膜与活性炭联用工艺解决富营养化水源水中藻类问题在技术上是成熟的,在经济上是可行的。

Algae removal in eutrophicated raw water using combined microfiltration membrane and activated carbon process

The algae in lakes and reservoirs is very universal, and the treatment technology on algae removal is complex and difficult. It is more and more impending to enhance and improve the related technology. The application of membrane technology in water supply is an innovation in water treatment technology, and gradually becomes the most development outlook water treatment technology in the 21 century. The paper is on the basis of inheriting and absorbing reliable technology, using its in the engineering, and resolving the given projects. According to the newest water quality standards in the world, the paper puts forward the new process combining mieroporous filter with activated carbon to remove the algae. In addition, the paper analyses in detail the principle, content, object and scheme of the engineering on algae removal. We think that the application of the microfiltration has the better condition in China, and it can be used in the large engineering on the basis of constantly accumulating experiences. The application of the process combining microfiltration with activated carbon is reliable in technology and feasible in economy on removal of algae in eutrophicated waters.
