预氧化与化学混凝联合去除颤藻的研究进展

Research Progress of Removal of Oscillatoria Tenuis by Pre-oxidation and Chemical Coagulation

日趋严重的水体富营养化早已成为全球性的环境问题,藻类及其副产物给传统除藻工艺带来了很多不利影响,增加了水处理难度。本文对国内预氧化与化学混凝联合去除颤藻的研究和应用动态进行了概括总结,并系统分析各技术去除效果、局限性,展望了颤藻去除技术发展前景。同时也提出了存在的一些问题,便于今后的研究和应用中进一步改进和完善。

It was a worldwide environment problem that the eutrophication of fresh waters became 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 research on the coagulation removal of Oscillatoria tenuis by pre-oxidation with Kaolin at home was summerized.Meanwhile,removal efficiency and limitation of different methods were analyzed systematically and some scientific tendencies were prospected.Issues were put forward to facilitate study and further improve and perfect the application.
