With the acceleration of urbanization, the stone industry in mines has developed rapidly, and a large number of stone wastewater has also been brought. These wastewater contains a large number of chemical components. If not treated, it will not only pollute the environment, but also harm human health. Therefore, Mine stone wastewater Processing application has become an urgent problem to be solved. This article will focus on Stone wastewater treatment The importance, current situation, technology application, effect evaluation and other aspects of are described.
1、 Mine stone waste water treatment Importance of
Mine stone wastewater is generated in the process of stone processing, which mainly comes from the cleaning of stone processing equipment, stone cutting, grinding and other links. These wastewater contains a large number of chemical components, such as acid, alkali, heavy metal ions, etc. If not treated, it will cause serious pollution to the environment and harm human health. Therefore, the application of mine stone wastewater treatment is one of the important tasks of environmental protection and human health.
2、 Present Situation of Waste Water Treatment of Stone Materials in Mines
At present, the treatment methods of mine stone wastewater mainly include physical method, chemical method, biological method, etc. Among them, the physical method is mainly to remove solid impurities and harmful substances in wastewater through filtration, adsorption and other methods; The chemical law is to change the chemical properties of wastewater by adding chemicals to make it reach the discharge standard; The biological principle uses the principle of microbial degradation of organic substances in wastewater to transform them into harmless substances. However, these methods have some limitations in practical application, such as low processing efficiency, high cost, and complex operation. Therefore, it is necessary to further research and develop more efficient, economic and simple wastewater treatment technology.
3、 Technical application of waste water treatment of mine stone
1. Membrane separation technology: membrane separation technology is a new type of wastewater treatment technology, which has the advantages of high efficiency and selectivity. The technology uses membrane separation device to separate wastewater into particles with different particle sizes, so as to achieve effective separation of substances with different particle sizes. The application of this technology in the treatment of mine stone wastewater can effectively remove harmful substances in the wastewater and meet the discharge standard.
2. Biological treatment technology: biological treatment technology is a kind of wastewater treatment method that uses the principle of microbial degradation of organic substances in wastewater and converts them into harmless substances. The technology has the advantages of low cost, simple operation and high treatment efficiency.
