生化净水工艺系统节约混凝剂和液氯用量生产性研究

Research on a full scale tests of saving coagulants and liquid chlorine in the slightly polluted raw water purification by bio contact oxidation process.

用生化净水工艺和传统净水工艺系统进行了受污染姚江水源水的对比试验研究，以探讨生化系统节约的混凝剂和液氯用量。结果表明，在相同的净水条件下，生化工艺系统处理污染原水比传统净水工艺节约混凝剂硫酸铝５０％以上，节约液氯７５％～８０％，具有显著的经济、社会效益。

The parallel tests have been conducted to treat separatively the slightly polluted raw water in Yaojiang River by the biochemical water purification process and the traditional water purification process, in order to investigate the coagulants and liquid chlorine saved by the biochemical water purification system. The experiment results show that the biochemical process can save coagulants of above 50% and liquid chlorine of about 75%～80% under the same conditions of water treatment.It is more saving than the conventional process and has a remarkable economic and social benefits.
