With the development of China's paper industry, the sludge produced by the treatment of paper-making wastewater is also a new pollution. The paper-making sludge mainly comes from the primary sedimentation tank and biochemical tank. The paper-making sludge not only contains a lot of cellulose organic matter, nitrogen, phosphorus, potassium and other plant nutrients, but also contains trace heavy metals and pathogenic bacteria. According to this characteristic, the sludge can be processed into organic fertilizer, Sludge contains a lot of water. How to remove the water?

 

In papermaking industry, pressure filtration is usually used to remove water from sludge. Before the sludge is concentrated and mechanically dewatered, the sludge needs to be treated with chemicals. Due to the different papermaking processes, the chemicals are not the same. Generally, the inorganic flocculants such as polyaluminum chloride and ferrous sulfate are added. The most commonly used and effective flocculant is polyacrylamide, Cationic polyacrylamide has its unique advantages in the treatment of papermaking sludge, such as the formation of large flocs, more effluent in the process of pressure filtration, low moisture content of pressed mud cake, and the moisture content of mud cake can reach about 75%, which is convenient for the reprocessing of mud cake. Mud cake can be further processed into organic fertilizer to turn waste into treasure.
