摘要
杭州市绕城公路有内河470多条。自1996年开始,市政府就每年拨款对市内重要河道按照"截污、驳坎、疏浚、引水、绿化"的模式进行河道整治,现今仍有许多重大问题急需解决。特别是水体的富营养化导致水中藻类泛滥,其面积、强度以及藻毒素的含量均在大幅度增长。从物理、化学、生物等方面介绍了几种藻类去除方法,探讨了除藻技术今后的发展研究方向。
There are more than 470 rivers in the ring road of Hangzhou.The city's municipal government has appropriated annual funding for regulation of important rivers according to the ' sewage interception,barge hom,dredging,diversion of water,virescence ' model since 1996.However,many mayor issues are not resolved yet.Especially,algae overflow induced by water eutrophication showed that area strength and content of toxin are in substantial growth.The current study introduced several methods of removing algae by means of physics,chemistry,biology,etc.This paper also discussed the future development technology of algae removal.
