废水分类的拓展研究

Research on Waste Water Classification

目前全国每年产生的废水量很大,而且废水所含的污染物也多,如何处理是个大问题。做好废水分类是治理废水的前提,废水分类有多种方法。有依据废水来源进行分类的,有依据废水所含的污染物有无毒性进行分类的,等等。本文将依据机械蒸汽压缩工艺对废水进行分类,表征指标有:黏度、结垢性、pH值、沸点等,从而将废水分为三类。

At present, a lot of wastewater is produced every year, and there are also many pollutants in the wastewater, how to treat it is a major problem. The classification of wastewater is a prerequisite for wastewater treatment.The classification of wastewater includes many methods, such as classification based on sources of wastewater, classification based on toxicity of wastewater, and so on. In this article, based on mechanical vapor compression technique, wastewater was classified. Characterization indexes included viscosity, scaling, p H and boiling point. According to these indexes, wastewater was divided into three categories.
