The reduction of the Screw sludge dewatering machine is very large and fluid in the process of operation due to the high moisture content of the sludge. After the above process, the sludge volume is reduced to one-tenth of the original, and the liquid is converted into a solid state, which is convenient for transportation and consumption.
Stabilization of the screw sludge dewatering machine: The sludge has a high content of organic matter, which is highly prone to spoilage and produces foul odor. After the treatment in the digestive stage of the above process, some of the easily spoiled organic matter is decomposed and transformed, which is not easy to be spoiled, and the malodor is greatly reduced, which is convenient for transportation and disposal.
The harmlessness of the screw sludge dewatering machine: In the sludge, especially the primary sludge, it contains a large number of pathogenic bacteria, parasitic eggs and viruses, which is easy to cause widespread spread of infectious diseases. Through the digestion stage in the above process, most of the aphid eggs, pathogens and viruses can be killed, and the sanitary indicators of the sludge are greatly improved.
The sludge of the screw sludge dewatering machine contains abundant nitrogen, phosphorus and potassium, which is an organic fertilizer with high fertilizer efficiency. Through the digestion stage in the above process, the organic matter can be converted into biogas, and the heat can be utilized, and the fertilizer efficiency can be further improved. The processes commonly used for sludge concentration include gravity concentration, centrifugal concentration, and air flotation. Sludge digestion can be divided into two categories: anaerobic digestion and aerobic digestion.
