城市供水中藻类去除技术的研究进展

A Review of Studies on Treatment Techniques for Algae in Water Supply

日趋严重的水体富营养化已成为全球性的环境问题,藻类及其副产物给传统净水工艺带来了诸多不利影响,增加了水处理难度。本文对饮用水中藻类各种去除技术进行了具体的论述,并系统分析各技术去除效果、局限性,展望了藻类去除技术发展前景。指出目前控制饮用水中藻类污染必须将水源污染综合治理、强化预氧化工艺、优化常规工艺结合起来。

It has been a worldwide environment problem as the eutrophication of fresh waters become more and more serious. In drinking water supplies with conventional process, algae and its by - product can cause many influences of negative so that it is difficult to get rid of them. The treatment techniques for algae in drinking water were introduced in this article, Meanwhile, removal efficiency and limitation of different methods were analyzed systematically and some scientific tendencies were prospected. It was suggested that combination of integrated management to the source water pollution, enhancing pre - oxidization and optimizing conventional process were the feasible ways to control the algae pollution at present.
