活性炭-超滤深度处理工艺对三氯乙醛生成潜能的影响及其对饮用水中有机物的去除
Influence on chloral hydrate formation potential and removal for organic matter in drinking water by activated carbon and ultrafiltration advanced treatment process
摘要
Abstract
To figure out removal capacity for chloral hydrate formation potential (CHFP) and organic matter by the activated carbon and ultrafiltration advanced treatment process,CHFP and related organic indicators during a activated carbon and ultrafiltration advanced treatment process were measured monthly for a year for a drinking water treatment plant in the south of China.The results indicated that CHFP in raw water presented a trend of seasonal variation and high in high temperature season (from May to September),whose scopes were 15.50 to 64.00 μg · L-1.The removal rates range for CHFP,TOC,CODMn and UV254 were 37.42％ to 69.12％,25.25％ to 66.71％,27.33％ to 61.25％ and 21.80％ to 72.46％ by the activated carbon and ultrafiltration advanced treatment process,separately.Meanwhile,the mean removal rates for them were 54.51％,39.21％,45.04％ and 42.91％,respectively.In addition,coagulation sedimentation played an essential role in the removal for CHFP and organics.Especially,activated carbon filter removed TOC and ultrafiltration removed CHFP and CODMn effectively.It is suggested that ozone should combine activated carbon filter to remove CHFP and organic matter in the water plant design and operation as far as possible,which further promotes the improvement of drinking water quality.关键词
