强化常规水处理工艺的设计应用案例分析

Design and Application of Enhanced Conventional Water Treatment Process

介绍了强化常规水处理工艺的技术措施及关键,并以某城市处理规模为30×104m3/d的水厂为例,进行了强化常规水处理工艺的设计应用案例分析。该水厂以该市大(2)型水库水为水源,其水质具有低温、低浊、水体中胶粒电位高、微污染、处理难度大等特点,根据实际情况采用了预氧化+强化常规处理工艺方案,介绍了相关工艺设计技术参数,并针对水厂运行中存在的问题提出解决措施。目前,该水厂已运行3年多,出厂水水质达标,其设计及运行可为类似水源地区的水厂建设提供技术参考。

The technical measures and key points oI enhanced conventional water treatment processes were introduced. The design and application of enhanced conventional water treatment proces- ses used in a waterworks with treatment capacity of 30 x 104 m3/d were analyzed. The water source for the waterworks is a large reservoir and characterized by low temperature, low turbidity, high potential of colloidal particles in water, slight pollution and difficult treatment. The design adopted the pre-oxidation plus enhanced conventional treatment processes. The related process design parameters were presented, and the solutions to problems existing in the operation were proposed. The waterworks has operated for more than three years with a finished water quality meeting the standard, and its design and operation provide technical reference for construction of waterworks in similar water source areas.
