常规给水工艺的除污染效果及其强化

通过在哈尔滨绍和水厂的现场模型试验及该厂运行监测数据的研究,证明在出水CODMn的质量浓度不超过3mg/L的条件下,常规给水工艺能去除原水中约60%~70%的CODMn,认为强化常规工艺是不容忽视的除污染途径之一。通过烧杯试验就除污染的最佳混凝剂和混凝条件做了进一步探讨,提出应兼顾除浊与除污染的需要,合理选择混凝剂和混凝条件。在生产实践中,应充分利用常规工艺的除污染效能,从而以最经济、简捷的方式解决饮用水除污染问题。

Pollution Removal Effect of Conventional Water Supply Process and Enhancement Thereof

It is proven through the site model tests made in Harbin Shaohe Portable Water Plant and the study of the data measured during the operation of the said plant that conventional water supply processes can remove about 60% ~ 70% of the CODMn in the raw water when the mass concentration of CODMn of the effluent water does not exceed 3 mg/L and, therefore, it is believed that the enhancement of conventional processes is one of the ways nonnegligible for pollution elimination. A further approach is made through beaker tests on optimum coagulating agent and coagulation conditions for pollution elimination, based on which it is believed that it is necessary to take into consideration the need of eliminating both turbidity and pollution and to rationally select coagulants and coagulation conditions. In productive practice, full use should be made of the pollution eliminating effect of conventional processes, so as to resolve the issue of eliminating the pollution of drinking water in a most economic and easiest way.
