Description

A high-efficiency treatment device for industrial sewage

technical field

The invention relates to the technical field of chemical industry, in particular to a high-efficiency treatment device for industrial sewage.

Background technique

Industrial wastewater refers to the wastewater and waste liquid discharged during the process of technological production, which contains industrial production materials, intermediate products, by-products and pollutants produced in the chemical production process that are lost with water, and is responsible for environmental pollution, especially water pollution. important reason. Although the treatment of industrial wastewater started as early as the end of the 19th century, due to the complex composition and changeable nature of many industrial wastewater, there are still some technical problems that have not been completely resolved.

According to the degree of pollution, industrial wastewater can be divided into two types: production wastewater and production wastewater. Production wastewater refers to water that is slightly polluted or temperature-increased during use (such as equipment cooling water); production sewage refers to water that is severely polluted during use, and most of them are seriously harmful. 2. According to the chemical properties of the main pollutants contained in industrial wastewater, it can be divided into inorganic wastewater mainly containing inorganic pollutants, organic wastewater mainly containing organic pollutants, mixed wastewater containing both organic and inorganic substances, heavy metals Waste water, waste water containing radioactive substances and cooling water contaminated only by heat. For example, electroplating wastewater and wastewater from mineral processing are inorganic wastewater, and wastewater from food or petroleum processing is organic wastewater.

The sewage needs to be treated before being discharged to meet the discharge standards. The current sewage treatment generally includes processes such as filtration of large impurities, adding sedimentation agents and sedimentation. However, in the current sewage treatment, 1. Large impurities only pass through the filter screen For filtering, this kind of filtering method will easily lead to the clogging of the filter screen, and it is necessary to manually clean up the residue at the filter screen; The binding of ions is not uniform enough, which in turn leads to incomplete settling.
