There are usually three types of classification methods:

The first is classified according to the chemical nature of the main pollutants contained in industrial wastewater. Wastewater dominated by inorganic pollutants is called inorganic wastewater, while wastewater dominated by organic pollutants is called organic wastewater. For example, wastewater from electroplating and mineral processing is inorganic wastewater; wastewater from food orpetroleum, processing is organic wastewater.

The second is classified according to the products and processing objects of industrial enterprises, such as metallurgical wastewater, papermaking wastewater,cokewastewater, metal pickling wastewater, chemical fertilizer wastewater, textile dyeing wastewater, dye wastewater, leather wastewater,pesticidewastewater, power plant wastewater, etc.

The third 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, oil-containing wastewater, sulfur-containing wastewater, organic phosphorus-containing wastewater, and radioactive wastewater.
