摘要
以北方某资源型缺水城市采用臭氧-生物活性炭深度处理工艺的净水厂为研究对象,围绕净水厂饮用水消毒副产物沿净水工艺流程的生成规律开展研究,提出相应控制措施建议。生产性试验结果表明:净水工艺对三卤甲烷生成势的平均去除率为39.23%,臭氧氧化对氯代三卤甲烷生成势有较好的控制效果,沿净水工艺流程,氯代三卤甲烷生成势占比大幅降低,溴代三卤甲烷生成势占比大幅升高;净水工艺对二氯乙酸前体物去除效果不明显,对三氯乙酸生成势平均去除率可以达到20.24%;试验期间对净水厂各净水工艺单元进行取样,结果均未检测出溴酸盐和甲醛。
The variation law of effluent disinfection by-products formation potential(DBPFP)of the water treatment process units was studied on a water supply plant employing ozonation-biological activited carbon(O3-BAC)process in the water resources scarcity city of North China.The productive experiment results showed the average trihalomethanes formation potential(THMFP)removal efficiency of the water treatment process was 39.23%,ozonation had favorable controlling effect over chlorine substituted THMFP,the proportion of chlorine substituted THMFP decreased drastically while bromide substituted THMFP increased along the water treatment process.The dichloroacetic acid removal of the water treatment process was not obvious while the trichloroacetic acid removal efficiency reached 20.24%and bromated and formaldehyde in the effluent of water treatment process units were not detected during the above experiment.
