当前国内外给水处理技术的一般工艺流程主要仍是混凝、沉淀、过滤和消毒。随着近代科学技术的发展,给水处理工艺的各个领域也不断改进和提高。现仅就混凝药剂、沉淀设施及过滤技术三方面的国内外发展趋向作一粗浅的介绍。混凝药剂在现代给水处理技术中混凝过程占有十分重要的地位。混凝过程本身并不是完全独立的,它为后续的沉淀、过滤等工艺过程准备条件,它是组成这些净化过程的必要的先
Currently, the general process flow of domestic and foreign water treatment technologies is still mainly coagulation, sedimentation, filtration and disinfection. With the development of modern science and technology, various areas of the water treatment process have been continuously improved and improved. Only a brief introduction is given on the development trends of coagulants, sedimentation facilities and filtration technologies at home and abroad. Coagulation agents play a very important role in the coagulation process in modern water supply treatment technologies. The coagulation process itself is not completely independent. It prepares conditions for subsequent precipitation, filtration and other processes. It is necessary for the formation of these purification processes.
