Principles of Industrial Wastewater Treatment1. Prioritize the use of non-toxic production processes to replace or reform backward production processes, as far as possible to eliminate or reduce the production of toxic and harmful wastewater. 2. In the process of using toxic raw materials and producing toxic intermediate products and products, strictly operate and supervise, eliminate drips, reduce losses, and use reasonable processes and equipment as much as possible. 3. Wastewater containing highly toxic substances, such as heavy metals, radioactive substances, high-concentration phenol, cyanide wastewater, should be separated from other wastewater in order to treat and recover useful substances. 4. Wastewater with large flow and light pollution should be properly treated and recycled, and should not be discharged into sewers, so as not to increase the load of urban sewers and urban sewage treatment. 5. Organic wastewater similar to urban sewage, such as food processing wastewater, sugar wastewater, papermaking wastewater, can be discharged into the urban sewage system for treatment. 6. Some toxic wastewater that can be biodegraded, such as phenol and cyanide wastewater, should be treated first and discharged into urban sewers in accordance with the allowable discharge standards, and then further biochemical treatment. 7. Containing toxic waste water that is difficult to biodegrade, it should be treated separately and should not be discharged into urban sewers. The development trend of industrial wastewater treatment is to recycle wastewater and pollutants as useful resources or implement closed-circuit cycles.
