【 摘 要 】

A new water purification equipment was introduced, especially the section of spiral lamellas. Utilization of spiral lamellas made the sedimentation space reach to 100%, not only improving sedimentation efficiency and reducing the cover space, but also saving investment. Production test results showed that the new water purification equipment with spiral lamellas had characteristics of excellent treatment efficiency and high shock resistant capacity. As the treatment water volume was 240 m3/d, when the turbidity, CODMnand UV254were 203 NTU, 1.90 mg/L and 0.030 cm-1in raw water, they were 0.32 NTU, 0.72mg/L and 0.011 cm-1respectively in effluent water, which could fully meet the drinking water hygiene requirement.
