| 摘 要： | 为研究不同填料对指示菌的去除效果,选取沸石、无烟煤、页岩、蛭石、陶瓷滤料、砾石、钢渣、生物陶粒8种填料,进行垂直流人工湿地模拟柱净化污水试验。结果表明,8种填料中对3种指示菌(异养细菌、大肠菌群和粪链球菌)去除率较高的为钢渣(99.9%)和无烟煤(95.9%),推测主要是因为其出水分别呈碱性和酸性造成。除钢渣和无烟煤外,去除率较高的为沸石和蛭石,去除率较低的为陶瓷滤料和生物陶粒。相关分析结果表明6种填料(不包括钢渣和无烟煤)对指示菌去除率与填料的渗透系数间存在负相关关系,推测它们主要是通过过滤吸附的机制去除指示菌。

| Abstract: | In order to study effect of fillings on removal of indicator bacteria(heterotrophic bacteria,coliforms group,fecal streptococcus),zeolite,anthracite,shale,vermiculite,ceramic filter media,gravel,blast furnace steel slag and bio-ceramic were chosen as fillings in columns of simulated wetland in a wastewater treatment experiment.Results show that anthracite and steel slag were the highest in bacteria-removing efficiency,being 95.9% and 99.9% respectively,probably because the effluent from the two columns was ... |
