摘　　要：针对某些净水厂新建或改扩建项目投资有限、用地紧张、原水低温低浊且伴有突发性高浊度和一定程度有机污染的特点,从减少工程投资、节约占地面积、优化水处理流程和提高水处理效果的角度出发,将中置式高密度沉淀池工艺与浸没式超滤膜工艺相结合,研发出一种新型的水处理工艺——沉淀膜滤组合工艺。经过对沉淀膜滤组合工艺内沉淀部分、膜滤部分和辅助部分的布局和功能优化,合理地解决了由于组合工艺承载功能多、构造复杂等所造成的问题。研发成果已设计应用于某地10万m3/d规模净水厂的改扩建项目中,可以预计,该新型组合工艺在老水厂工艺升级改造或新建水厂项目中均具有广泛的应用前景。According to the characteristics,such as limited investment,limited land,low temperature and turbidity,sudden high turbidity,and organic pollution to some extent in raw water in some newly-built water treatment plant（WTP） or extension WTP project,in order to reduce project investment and floor area,optimize water treatment process and improve the treatment effects,a new water treatment process,sedimentation-ultrafiltration membrane combined process,was developed through the combination of intermediate high density sedimentation tank and immersed ultrafiltration membrane process.By optimizing the arrangement and function of high density sedimentation part,immersed membrane part and assistant part in the process,some problems from multi-function and complex structure were resolved.This research result has been adopted in a renovation and expansion project of some WTP with 100 000 m3/d scale.It can be predicted that this new-style process would be widely employed in both the upgrading projects of old WTP and newly-built WTP.
