桂林微污染饮用水源预处理工艺有效性试验

The Effectiveness on the Pretreatment Process of Micropollutant Drinking Water in Guilin

桂林漓江某河段水质数据表明,该段水源已劣于地表水环境质量标准Ⅲ类水质,通过对该水质进行的可生化性试验,可生化降解部分达到34.9%。粉末活性炭吸附与高锰酸钾氧化预处理试验其CODCr去除率分别达52%、45%,生物接触法CODCr去除率45%,粉末活性炭吸附和高锰酸钾氧化在现有给水处理工艺基础上稍加改造即可实施,生物接触氧化需新建接触氧化反应池。

The data of water quality of Li River of Guilin shows that the raw water is inferior to the third class of surface water quality of the China. By the biodegradability experiment for water quality, the percent of biodegradability reaches 3,1.9%. The removal rate of CODCr is 52% and 45% by the adsorption of power active carbon and potassium permanganate oxidation respectively, and the removal rate of biological contact is 45%. The former can be realized by slight improvement of constructed works and the latter need to be set up of contact oxidation tank.
