摘要
随着社会和时代发展,当前我国的金属冶炼工厂越来越多,造成了大量的废水污染问题,严重影响到了人们的居住环境和自然的生态环境,不断产生的废水流入到生态系统会危害居民的健康,因此我们要在金属冶炼过程中实行废水零排放技术。本文就关于当前我国金属冶炼化工废水排放问题进行了简要的分析,以工业废水的三种常见处理工艺中的水质作为参考数据,根据水质的数据和分析反馈,对当前我国的金属冶炼化工废水排放技术进行相应的建议和调整,进一步实现废水零排放技术,实现废水零排放,可以极大地减少废水的产生,减少污染物对人们居住环境的危害和对生态系统的破坏。
With the development of society and the times, there are more and more metal smelting factories in China, causing a large number of wastewater pollution problems, which seriously affect people＇s living environment and natural ecological environment. The continuously generated wastewater will flow into the ecosystem. It is harmful to the health of residents, so we have to implement zero-discharge technology in the metal smelting process. In this paper, a brief analysis of the current metal smelting chemical wastewater discharge problem in China is carried out. The water quality in the three common treatment processes of industrial wastewater is used as reference data. According to the water quality data and analysis feedback, the current metal smelting chemical wastewater discharge in China. The technology will make corresponding recommendations and adjustments to further realize zero-discharge wastewater technology and achieve zero discharge of wastewater, which can greatly reduce the generation of wastewater, reduce the harm of pollutants to people＇s livingenvironment and damage to ecosystems.
