摘　　要：在凌桥水厂中,其水质中的总氮和硫酸盐等指标已出现超标问题,且出水的高锰酸钾指数已达到限值,为此需要及时进行深度处理确保水质的供水。通过调查凌桥水厂以及该水厂中的水源现状,比选了两种(纳滤和臭氧活性炭)深度处理工艺,最终结果显示臭氧-活性炭工艺用在水厂深度处理工艺中的技术成熟,节约了投资和运行成本且此项工艺的水耗低。最后,介绍了工艺的流程、设计特点、主要设计参数以及处理效果。并通过工程实践证实了此项工艺的出水效果十分稳定,去除有机物的效率显著,最终确保了水厂出水水质能够满足GB5749—2006《生活饮用水卫生标准》的要求。The Lingqiao Water Plant exceeded the standards for total nitrogen,sulfate and other indicators.The potassium permanganate index of the effluent was approaching the limit.To ensure water supply,an advanced treatment process was urgently needed.This paper discusses the current situation of the Lingqiao Water Plant and its water source.A comparison of two advanced treatment processes(nanofiltration and ozone-activated carbon)found that the ozone-activated carbon process was mature,cost-efficient,and consumed little water.This paper introduces the process flow,design characteristics,main design parameters and treatment effect of the ozone-activated carbon process.Engineering practice proved that the effluent was stable and efficiently removed organic matter,enabling the plant to meet the Drinking Water Standard(GB5749—2006).
