通过分析水厂更换水源后的水质特点及水厂现有处理工艺存在的问题,提出采用水平管沉淀分离技术对水厂进行提标扩能改造的方案设计。主要介绍了本次改造的技术措施。通过采用在隔板絮凝池前增加高效絮核塔、将原有斜管沉淀池改造为水平管沉淀池的改造措施,使水厂出水水质达到《生活饮用水卫生标准》GB 5749—2006要求,并将水厂生产能力由目前的4×10~4 m~3/d左右提高至设计规模5×10~4 m~3/d。
By analyzing the characteristics of water quality after the replacement of water source by waterworks and the problems existing in the existing treatment processes of the waterworks, the scheme design of watermarking by scaling-up and expansion of horizontal pipe precipitation separation technology is proposed. Mainly introduced the technical measures for this transformation. Through the use of an efficient flocculation tower in the front of the flocculation tank, the transformation of the original inclined tube sedimentation tank into a horizontal tube sedimentation tank has been carried out so that the water quality of the effluent of the water plant meets the requirements of “Health Standard for Domestic Drinking Water” GB 5749-2006, And the water plant production capacity from the current 4 × 10 ~ 4 m ~ 3 / d or so to the design scale of 5 × 10 ~ 4 m ~ 3 / d.
