UV/H_2O_2联用工艺去除水中微量有机污染物的中试研究

Pilot study of UV/H_2O_2 combined process on removing micro organic pollutants in water

为了考察UV/H2O2工艺对微量有机物的去除效果,在砂滤池出水后接UV/H2O2高级氧化中试设备,并投加了特征污染物(阿特拉津、臭味物质2-MIB与Geosmine)。结果表明,UV/H2O2工艺对Geosmine去除效果最好,去除率能达到90%以上,对MIB和阿特拉津的去除效果比较接近,去除率均在50%以上,对UV254的去除率为20%～38%。在UV/H2O2工艺中无溴酸盐生成。

To study the removal efficiency of UV/H2O2 process on micro organic pollutants, UV/H2 O2 pilot equipment was used to treat the sedimentation effluent dosed with target pollutants （including Atrazine, odor matter 2 - MIB, and Geosmine）. The results showed ： UV/H2 O2 had the best efficiency on removing Geosmine with the removal rate over 90%. The removal effect of MIB and Atrazine was alike, and the removal rates both reached over 50%. The removal rate of UV254 was 20-38%. No bromate was formed in the UV/H2O2 process.
