多级活性焦工艺技术应用于某污水厂提标改造试验

Test of Multistage Active Coke Process Technology Applied in Upgrading and Reconstruction Project of WWTP

随着环保要求的提高,城市污水处理厂出水要求也越发严格,污水处理技术也在不断创新。某污水处理厂采用多级活性焦吸附技术处理生活污水和工业废水。对活性焦对污水有机污染物的去除效果进行中试试验,结果表明:多级活性焦吸附技术对COD的去除效果明显,COD去除率≥70%;出水达到地表IV类水水质要求,水质稳定、耐冲击负荷。

With the improvement of environmental protection requirements,requirements of effluent water quality of municipal WWTPs are more and more strict,and treatment technology is constantly innovating.Domestic sewage and industrial wastewater were treated by multistage active coke adsorption technology in a WWTP.A pilot scale test was conducted on removal effect of active coke on organic pollutants in sewage.Results showed that multi-stage active coke adsorption technology had an obvious effect on removal of COD,removal rate of COD≥70%,and effluent met requirements of IV criteria of surface water standard,with stable water quality and impact load resistance.
