Sewage is a general term for various kinds of sewage. The quality of domestic sewage and industrial wastewater is different, and the treatment methods used are different. It is necessary to classify this. So what are the principles for sewage treatment? What are the benefits of classification? 重庆一体化污水处理设备 小编为您分析一体化污水处理设备分类处理原则。 Next, the Chongqing integrated sewage treatment equipment editor will analyze the classification and treatment principles of integrated sewage treatment equipment for you.
Only by treating sewage by category can the integrated sewage treatment equipment achieve the maximum efficiency in the process of work. Today I will talk about the principle of classification of sewage treatment equipment:
1. The wastewater treated by the integrated wastewater treatment equipment contains highly toxic wastewater. For example, wastewater containing some heavy metals, radioactive substances, high concentrations of phenol, and cyanide should be diverted from other wastewater 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 urban sewers and sewage treatment plants. This type of wastewater should be recycled in the plant after proper treatment.
3. The most fundamental thing is to reform the production process and try to prevent the production of toxic and harmful wastewater during the production process. Such as replacing non-toxic materials or products with non-toxic materials or products.
4. In the production process that uses toxic raw materials and produces toxic intermediate products and products, reasonable technological processes and equipment are adopted, and strict operations and supervision are implemented to eliminate leakage and minimize the amount of leakage.
5. Organic wastewater whose composition and properties are similar to municipal wastewater, such as papermaking wastewater, sugar wastewater, food processing wastewater, etc., can be discharged into urban wastewater systems. Large-scale sewage treatment plants should be constructed, including simple and feasible treatment facilities such as biological oxidation ponds, sewage depots, land treatment systems, etc. which should be built according to local conditions. Compared with small sewage treatment plants, large sewage treatment plants can not only significantly reduce capital construction and operating costs, but also because of stable water volume and water 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 the allowable discharge standard after being treated in the factory, and further biologically oxidatively degraded by sewage treatment equipment.
7. Wastewater containing toxic pollutants that are difficult to biodegrade should not be discharged into urban sewers and exported to sewage treatment plants, but should be treated separately.
