摘要
在北京市某净水厂进行了臭氧催化氧化处理滤后水的中试,对各种操作条件下蜂窝陶瓷催化臭氧氧化/颗粒活性炭过滤工艺的净水效果进行了考察。结果表明,与臭氧单独氧化相比,臭氧催化氧化反应器中有较高的溶解性臭氧浓度,对天然有机物(NOM)及总有机物(TOC)的去除效果较好,三氯甲烷生成潜能(CHC l3FP)较低。臭氧催化氧化的后续活性炭滤柱上的生物量较多,出水TOC、UV254及CHC l3FP值也均低于臭氧单独氧化的后续活性炭滤柱出水。
A pilot-scale study was conducted in a drinking water treatment plant in Beijing, and the efficiency of ceramic honeycombs catalytic ozonation and its subsequent granular activated carbon （GAC） filtration was investigated at different operating conditions. Comparing with ozonation process operated in parallel, the concentration of dissolved ozone is higher in catalytic ozonation process, and more natural organic matter （NOM） and total organic matter （TOC） are removed by catalytic ozonation. The chloroform formation potential （CHCl3FP） also decreases on a larger scale in catalytic ozonation process. More biomass is attached on the GAC following catalytic ozonation process, and less TOC, UV254 and CHCl3 FP are detected in the effluent of catalytic ozonation - GAC process.
