该文介绍了国内一自来水公司三个水厂的两个原水水质、净水工艺及出厂水水质。结果显示第一水厂的出厂水质较为理想，第二水厂次之，第三水厂为第三。第三水厂由于水源的问题导致出厂氨氮季节性超标，建议采取有效措施改进水源水质，以提高出厂水质。第二水厂需进行工艺改造，实施臭氧活性炭深度处理以进一步提高供水水质。第三水厂一期系统臭氧生物活性炭池置于砂滤池后较二期活性炭滤池置于砂滤池前出水有机物CODMn及TOC略低，但两者基本相近。建议第三水厂采取必要的措施改进水源水质，或再增加一道臭氧生物活性炭工序。

Water plants with two different raw water qualities,purification processes and their effluent water qualities were introduced in this paper. The finished water quality of NO. 1 plant is the best,and the NO. 2 is better. Due to raw water quality problem No. 3 water plant’s finished water ammonia nitrogen hardly meets the standard of GB 5749-2006 seasonally. Effective measures should be taken to improve the effluent water quality of No. 3 water plant No. 2 water plant need technological transformation to implement advanced treatment of O3 actived carbon to improve finished water quality. The organic indexes of effluent water of first-stage system in No. 3 water plant,of which O3 actived carbon filter is located behind the sand filter,is a little better than that of second-stage system, of which O3 actived carbon filter is located before the sand filter. But their finished water qualities are approximately same. Necessary measures to improve raw water quality for No. 3 water plant or to apply an additional ozone BAC process are recommended.
