摘　　要：通过对梅林水厂和国内外现有处理污水方案比较,确定了梅林水厂净水工艺的优化设计方案;通过对原水pH值的调整,简化了PAC前馈投药数学模型;采用模拟沉淀池出水浊度作为投药控制的反馈信号,缩短了常规的用沉淀池出水浊度作为反馈信号而产生的滞后时间;用滤层水头损失和滤池出水浊度作为滤地反冲洗控制信号,比定时反冲洗提高了一个档次;根据沉淀池排放的污泥具有浓度高的特点,提出了用结团凝聚法处理污泥的泥处理工艺。Based on analysis of the available materials of meilin water purificationplant and the both advantages and disadvantages of water purification units at present, areasonable process of water purification is presented in this article. Dosage mathematicalmodel of PAC is simplified by adjusting pH value of the raw water. Postponed time ofreaction is shorten by using the exit turbidity of the model sendimention. Backwashingprocess is improved a lot by taking the head loss and exit turbidity of the aquazur filteras backwashing signals, and the pellet--coagulation process is used for disposing of thesludges.
