苏州河上游地区滨岸缓冲带试验基地设计思路

为探索控制农业面源污染的有效方法，改善河道水质，逐步修复河道原有生态功能和增加生物多样性，上海市在苏州河环境综合整治一期、二期工程实施的基础上，立项开展了苏州河环境综合整治三期工程实用技术研究。旨在通过选择苏州河上游区域某一自然河道，建立完整的滨岸缓冲带体系并进行现场试验，开展上海地区滨岸缓冲带的设计、建设和养护管理等方面的实践工作，同时考察滨岸缓冲带生物栖息地功能、滨岸带景观功能和改善河流水质功能等方面的功效。文章阐述了滨岸缓冲带试验基地设计中的一些思路，分析了基地选址及环境条件，从植被选择及其群落配置、坡度选择、取样管设置、面源污染防治试验工艺流程等方面进行了试验基地的设计。     

折流式水解反应器处理印染废水水温影响研究

在水温为5℃、9.7℃、14.9℃、19.7℃、23.5℃和31.1℃6种温度的条件下,应用折流式水解反应器对印染废水进行水解试验研究.结果表明,提高水温可增大COD、色度及UVA254的去除效率,相应的ORP值变小,pH值升高,水解程度加深.水温5℃时,水解效果较差;水温在10～23.5℃内,水解效果相对较好,31.1℃水解效果最好,研究结果能为工程应用提供一定的参考.
