Study on algae-laden water treatment of dissolved air flotation integrated with ·OH strong oxidation

Abstract

我国饮用水水源约有25%是湖泊水或河流库区水库水,高藻发生的频率与严重程度都呈现迅猛的增长趋势,因藻类大量繁殖引起的水源污染,造成自来水厂被迫减产或停产,严重地威胁城市供水和饮用水安全。本论文针对厦门九龙江北溪流域日益严峻的富营养化及水华爆发危及饮用水安全的重大问题,以大气压强电离放电生成羟基自由基(•OH)致死高藻水中藻类为核心,建立高效、经济、安全的高藻水处理的组合工艺,取得的主要成果如下: (1)以强电场电离放电产生•OH为核心,建立气浮-•OH强氧化组合工艺。在强电场电离放电形式下,O2解离、电离生成O2+、O(1D)、O(3P)等氧活性粒子,通过...About 25% of drinking water sources in China are lake or reservoir water in rivers, but there is a rapid growth in algae bloom frequency and severity in these water sources. The water pollution caused by algae bloom forces the waterworks to reduce the output or even stop production. This study aims at solving the increasing serious problems of eutrophication and algae bloom in Jiulong River in Xia...学位:工学硕士院系专业:环境与生态学院_环境工程学号:3312012115163
