For example, wastewater from electroplating and mineral processing is inorganic wastewater, and wastewater from food or petroleum processing is organic wastewater.
According to the products and processing objects of industrial enterprises, it can be divided into papermaking wastewater, textile wastewater, tanning wastewater, pesticide wastewater, metallurgical wastewater, oil refining wastewater, etc.
According to the main components of pollutants contained in wastewater, it can be divided into acidic wastewater, alkaline wastewater, phenol-containing wastewater, chromium-containing wastewater, organic phosphorus-containing wastewater and radioactive wastewater.
