Removal and relationship analysis of turbidity and microbial indicators in a municipal wastewater treatment plant

  • 摘要: 本研究考察了污水再生处理系统对颗粒物(包括浊度和粒径分布)和微生物指标(包括隐孢子虫、贾第鞭毛虫、粪大肠菌群和SC噬菌体)的去除特性以及不同指标间的相关关系。研究结果表明,污水再生处理系统对浊度的平均去除率为3.53-log,其中二级生化处理及砂滤对浊度的去除率较高,分别为1.52-log和1.35-log。粒径分析结果表明,絮凝沉淀后粒径均值达到最大值223.2 μm;而再生水中粒径均值最小,仅为5.8 μm。污水再生处理系统对各微生物指标的去除率为2.96-log~4.11-log。各处理单元中,二级生化处理单元对粪大肠菌群和SC噬菌体的去除率较高,分别为2.81-log及2.14-log;而砂滤对SC噬菌体去除效果较差,仅为0.18-log。从再生处理工艺整体上看,水样浊度、粪大肠菌群、SC噬菌体和两虫浓度具有显著相关性。而对于单个取样点,除污水厂进水中 SC噬菌体和两虫浓度表现出一定相关性外,其他情况下各指标与两虫浓度间均无显著相关关系。
