The paper industry is one of the six major industrial pollution sources in the world, accounting for about 10% of China's total industrial wastewater. Papermaking wastewater is mainly high-concentration organic wastewater and contains pollutants such as lignin, residual alkali, sulfide, and chloride. It is characterized by a large amount of wastewater, a high concentration of COD, and a large amount of fiber suspended matter in the wastewater.

Wastewater from the paper industry mainly comes from the two processes of pulping and papermaking in the paper industry. Pulp is the process of separating fibers from plant raw materials into pulp, which is then bleached. Papermaking is the process of making pulp by diluting, shaping, pressing, and drying the pulp. Both processes discharge large amounts of wastewater.

There are mainly three types of wastewater produced in the pulp and paper production process: black liquor, middle stage wastewater and paper machine white water. Black liquor is mainly cooking and pulping wastewater, the main components are lignin, cellulose, hemicellulose, monosaccharides, organic acids, sodium hydroxide, etc .; middle water includes pulp washing, screening, and bleaching wastewater, which contains a large amount of acid and alkali ; Paper machine white water is papermaking workshop wastewater, which contains a large amount of fiber and fillers and rubber added during the production process. Among them, the environmental pollution of cooking wastewater is the most serious.

So many different wastewaters are generated in the pulp and paper process, and the centrifuge is the key equipment for wastewater treatment. Due to the particularity of wastewater treatment in the pulp and paper industry, it requires centrifuges to have higher wear resistance and corrosion resistance. The centrifuge designed by Jinhua Zhengbang uses better wear protection and high quality stainless steel. Therefore, the solid-liquid separation and sludge dewatering in the papermaking process of the pulp and paper mill can be performed excellently by the Zhengbang centrifuge.
