Abstract：

Langshan plant in Nantong is the largest submerged ultrafiltration membrane water treatment plant at present, which takes Yangtze water as its source water. The water plant adopts a flexible treatment process which can be spanned. It focuses on the combination of conventional pretreatment process coagulation sedimentation and submerged ultrafiltration membrane, ozone activated carbon process and submerged ultrafiltration membrane technology, which further validates that ultrafiltration membrane technology is an easy combination and effective advanced purification process. The operation results of the water plant show that the energy consumption is low, the effluent quality is stable, and the turbidity is kept below 0.1NTU continuously, which has a typical demonstration significance for the application of water treatment technology in Waterworks in the Yangtze River Basin.
