Background technique

With the acceleration of urbanization and industrialization in China, the demand gap for water resources is also increasing. In this context, the sewage treatment industry has become an emerging industry, and is currently in the same important position as the tap water production, water supply, drainage, and reclaimed water reuse industries. Among them, the paper industry ranks first among the five high water consumption industries in my country. The water consumption per ton of paper in domestic paper mills is as high as 100 cubic meters, which is almost 10 times the world average level. Therefore, the water source pollution and environmental pollution caused by my country's paper industry And the waste of water resources is very serious. At present, some manufacturers in China's paper industry have effectively achieved the effect of sewage treatment by building sewage treatment projects. However, the cost of these sewage treatment projects is very high, and ordinary manufacturers cannot establish sewage treatment projects or maintain sewage treatment projects. Therefore, many manufacturers Still choose the way of direct sewage discharge, papermaking sewage can not be effectively treated, water pollution and environmental pollution are serious, and the pollutants contained in papermaking sewage are mainly short fibers, microfibers, silt and impurities, etc., the direct discharge of papermaking sewage is still It will cause a waste of fiber resources. Therefore, how to effectively treat papermaking sewage to minimize the total investment in pollution control, recycle fiber pulp, and turn waste into treasure is an urgent problem for paper industry technicians. The commonly used recycling treatment The method is to add flocculants to the papermaking sewage, mix and react with the sewage to absorb the dirt, and finally extract the fiber pulp through precipitation. However, the traditional flocculation is to directly add flocculants, resulting in indiscriminate contact between the sewage and the flocculants, and improper mixing. Even, the flocculation effect is not ideal, which affects the sewage treatment effect.
