Industrial wastewater refers to the wastewater and waste liquid discharged during the process of production、 which contains industrial production materials、 intermediate products、 by-products that are lost with water、 as well as pollutants generated during the production process. It is a major cause of environmental pollution、 especially water pollution. Although the treatment of industrial wastewater began as early as the late 19th century、 there are still some technical problems that have not been fully solved due to the complex composition and variable properties of many industrial wastewater. The treatment methods for water can be summarized into three ways: ① The most commonly used method is to obtain the required water quality by removing some or all impurities from the raw water. ② Obtain the required water quality by adding new ingredients to the raw water The processing of raw water does not involve removing impurities or adding new ingredients. Softening water treatment: Chemical "resin" treatment、 such as softening with hard water P>
