苏州庙港水厂深度处理工程(一期)设计

Design of Phase I Advanced Treatment Project of Miaogang Water Treatment Plant in Suzhou

针对原水有机物含量较高、嗅味较为严重等问题,苏州吴江区庙港水厂进行深度处理改造,并根据场地条件分阶段实施。为了适应生产系统,对预臭氧接触池、深度处理综合池和配套管线进行了优化设计。改造后,出水水质符合《生活饮用水卫生标准》(GB 5749—2006),出厂水CODMn由2.22 mg/L降低至1.62 mg/L,氨氮由0.04 mg/L降低至0.03 mg/L。项目投资回收期为11.85 a,经济性良好,可为同类工程案例提供参考。

Faced with the problems of high organic matter and serious smell in the raw water,advanced treatment reconstruction project is taken in Miaogang WTP of Wujiang District,Suzhou.Advanced treatment is carried out in stages according to site conditions.In order to adapt to production system,pre-ozone contact tank,advanced-treatment tank and pipelines are optimized.After the reconstruction,effluent quality can meet Sanitary Standard for Drinking Water(GB 5749—2006),CODMn is reduced from 2.22 mg/L to 1.62 mg/L,and ammonia nitrogen is reduced from 0.04 mg/L to 0.03 mg/L.The project has good economic benefits and the payback period is 11.85 a,providing reference for similar projects。
