There are usually three types of industrial wastewater classification:

The first type is classified according to the chemical properties of the main pollutants contained in industrial wastewater. The inorganic pollutants are mainly inorganic wastewater, and the organic pollutants are mainly organic pollutants. For example, electroplating wastewater and wastewater from mineral processing are inorganic wastewater; wastewater from food or petroleum processing is organic wastewater.

The second is classified according to the products and processing objects of industrial enterprises, such as metallurgical wastewater, papermaking wastewater, coking coal gas wastewater, metal pickling wastewater, chemical fertilizer wastewater, textile printing and dyeing wastewater, dye wastewater, tannery wastewater, pesticide wastewater, power station wastewater. Wait.

The third type is classified according to the main components of the pollutants contained in the wastewater, such as acidic wastewater, alkaline wastewater, cyanide-containing wastewater, chromium-containing wastewater, cadmium-containing wastewater, mercury-containing wastewater, phenol-containing wastewater, aldehyde-containing wastewater, and oily wastewater. , sulfur-containing wastewater, organic phosphorus wastewater and radioactive wastewater. The industrial wastewater treatment process adopts modern automatic control technology, sets up necessary monitoring instruments, realizes automatic management, improves management level; has certain flexibility and adjustment room for handling system operation, industrial wastewater treatment process to adapt to changes in water quality and quantity; industrial wastewater treatment process Beautiful design and reasonable layout. Sewage treatment companies try to take measures to reduce the impact on the surrounding environment and properly control the smell and noise.
