人工快速渗滤系统的发展与展望

在总结众多试验结果的基础上,阐述了人工快速渗滤系统(CRI)对主要污染元素氮、磷、有机物的主要去除机理和去除过程,以及净化过程中的限制因素。此外,还分别介绍了CRI系统的主要运行参数,总结了不同滤料、温度、配水方式对系统净化效率的影响和目前国内对CRI系统的强化和改良进展。针对目前面临的主要问题,提出了今后CRI系统应进行的主要研究内容和技术攻关重点为硝态氮的强化去除,并对其应用方向进行了展望。

Development and Prospects of Constructed Rapid Infiltration

Based on summarizing a lot of experiment results,the paper expounded the main removal mechanisms and processes of nitrogen(N),phosphorous(P),and organic matter in constructed rapid infiltration(CRI) as well as the limiting factors during the purification processes.In addition,the major operating parameters were introduced,the impacts of filter material,temperature,and water distribution mode on purifying efficiency were summarized and the domestic progresses of CRI improvement at present were summarized in ...
