  • 摘要: 以我国南方某活性炭-超滤深度处理工艺水厂为研究对象,对工艺过程中三氯乙醛生成潜能(CHFP)及相关有机物指标进行为期1年每月1次的监测,以明晰活性炭-超滤深度处理工艺对CHFP及有机物的去除能力。结果表明:原水CHFP均呈现一定的季节性变化趋势,高温季节(5—9月)相对较高,范围为15.50～64.00 μg·L-1,活性炭-超滤深度处理工艺对CHFP 、TOC、CODMn和UV254去除率范围分别为37.42%～69.12%、25.25%～66.71%、27.33%～61.25%和21.80%～72.46%,平均去除率分别为54.51%、39.21%、45.04%和42.91%；混凝沉淀单元在CHFP和有机物指标去除中均起主要作用,炭滤单元对TOC有较好的去除作用,超滤单元对CHFP和CODMn有较好的去除作用。建议水厂设计与运行中将臭氧与活性炭滤池联合使用,以协同去除CHFP和有机物,进一步提高供水水质。
    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, CODMn 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 CODMn 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.
