Polyurethane rubber wastewater treatment classification principles Author: polyurethane rubber wastewater treatment are also different, the need for this classification process, the polyurethane rubber wastewater treatment is based on what principles to deal with, what good classification process. Next, we will analyze the principles of classification and treatment of polyurethane rubber wastewater treatment. Only by treating wastewater by categories can the polyurethane rubber wastewater treatment be effective in the process of work. Today, I will talk about the classification treatment principles of polyurethane rubber wastewater treatment: 1. The wastewater treated by polyurethane rubber wastewater treatment contains highly toxic waste water, such as Wastewater containing some heavy metals, radioactive substances, high-concentration phenol, cyanide, etc. should be separated from other wastewaters to facilitate the treatment and recovery of useful substances. 2. Some wastewater with large flow and light pollution, such as cooling wastewater, should not be discharged into the sewer, so as not to increase the load on the urban sewer and wastewater treatment plant. This type of wastewater should be recycled in the factory after proper treatment. 3. The fundamental thing is to reform the production process, as far as possible to prevent the production of toxic and harmful wastewater. Such as replacing toxic materials or products with non-toxic materials or products. 4. In the production process of using toxic raw materials and producing toxic intermediate products and products, adopt reasonable technological processes and equipment, and implement strict operation and supervision to eliminate leakage and minimize loss. 5. Organic wastewater whose composition and properties are similar to urban wastewater, such as papermaking wastewater, sugar wastewater, food processing wastewater, etc., can be discharged into the urban wastewater system. Including simple and feasible treatment facilities such as biological oxidation ponds, sewage reservoirs, and land treatment systems built according to local conditions. Compared with small wastewater treatment plants, polyurethane rubber wastewater treatment can not only significantly reduce the capital construction and operating costs, but also because of the stable water volume and quality, it is easy to maintain good operating conditions and treatment effects. 6. Some biodegradable toxic wastewater, such as phenol and cyanide wastewater, can be discharged into urban sewers according to allowable discharge standards after being treated in the factory, and the wastewater treatment equipment is further subjected to biological oxidation degradation treatment. 7. Wastewater containing toxic pollutants that are difficult to biodegrade should not be discharged into urban sewers and sent to wastewater treatment plants, but should be treated separately.
