Characteristics of mechanical processing wastewater Polyester-based processing technology Features of mechanical processing wastewater Polyester-based processing technology Along with the rapid development of science and technology, machining has become ubiquitous in both domestic and overseas industries, Laid the foundation for development and brought great contributions to human development. Although the machining industry to improve our standard of living, resulting in humanity now can not be separated from the machining industry, but with the large machining industry, machining industry, the greater the pollution. The mechanical processing industry is a large household water consumption, the resulting waste water is not only high oil, but also contains a variety of heavy metal ions, these metal ions are toxic, great harm to the human body and the environment, so the processing of mechanical waste Gradually attracted the attention of people. Due to the widespread use of emulsifiers in the machining process, these emulsifiers change from white to black after machining and can also produce malodour, and due to the use of emulsifiers, the amount of oil in the machining waste water is also large, Mechanical processing wastewater treatment difficulty. At present, the problem of high oil content and heavy metal exceeding serious standards in domestic wastewater treatment is mainly based on the physico-chemical method, which is commonly used to improve the purification effect of water quality by adding polish additives such as polyaluminum chloride in the treatment process, mainly As the polyaluminum chloride water purification agent such as degreasing and removal of heavy metals excellent performance, combined with polyaluminum chloride is a civilian products, not only easy to operate, the effect is more significant, so now polyaluminum chloride Water purification additives have been the promotion of the industrial sector. Today, domestic and foreign machinery processing industry in addition to a single use of physical and chemical treatment of waste water, there are some enterprises using advanced treatment, biochemical treatment methods. However, in spite of this, physicochemical pretreatment is usually used first when using these treatment processes, and it is also commonly used to process the additives such as polyaluminum chloride. The main purpose is to improve the treatment effect of water quality and save the cost of enterprise water treatment.
