在原水水质较差的情况下,随着卫生部新颁《生活饮用水卫生标准GB 5749-2006》的实施,上海市各常规处理水厂面临全面深度水处理改造重任。松江二水厂也需实施深度水处理改造以保证出厂水达到国家新颁标准的要求。本文介绍了松江第二水厂在面对原水水质较差、厂区用地紧张、电力负荷不足等诸多难题的情况下,通过深入研究、精心设计,将原有平流式沉淀池进行改造,在常规处理工艺基础上新增O_3-BAC深度水处理工艺,实现提升供水水质工程实例。
In the case of poor raw water quality, with the new Ministry of Health issued “drinking water health standard GB 5749-2006” implementation, Shanghai conventional water treatment plant is facing a comprehensive deep-water treatment transformation task. Songjiang Second Waterworks also need to implement the transformation of the depth of water treatment to ensure that the factory water to meet the new national standards issued by the request. This paper introduces the Songjiang second waterworks in the face of poor water quality, factory land shortage, power shortage and many other problems, through in-depth study and meticulous design, the original advection settling tank transformation, in the conventional treatment Added O_3-BAC depth water treatment process based on the process, to improve the quality of water supply engineering examples.
