Background

Sludge treatment is a process of carrying out reduction, stabilization and harmless treatment on sludge. The higher the degree of wastewater treatment, the more sludge residue will be produced to be treated. A general sewage treatment plant must be provided with a sludge treatment facility unless the sewage is treated using land treatment or a sewage pond. For modern sewage treatment plants, the treatment and disposal of sludge has become the most complex and costly part of the operation of sewage treatment systems. Before sludge treatment, firstly, the classification of sludge is known, and then the method for sludge treatment can be determined, namely, physicochemical sludge treatment sludge discharged from a sedimentation tank or a concentration tank of a water plant is classified, the sludge belongs to medium-fine particle size organic and inorganic mixed sludge, the compressibility and the dehydration performance are general, and residual activated sludge discharged from a secondary sedimentation tank of a domestic sewage plant is classified, belongs to hydrophilic and fine particle size organic sludge, and has poor compressibility and dehydration performance. Sorting sludge produced by industrial wastewater treatment and discharged by a concentration tank through physicochemical and biochemical mixed sludge treatment: the sludge belongs to medium-fine particle size mixed sludge, the dewatering performance of a fibrous body is better, and the other compressible performance and the dewatering performance are common. Classifying sludge generated by the treatment of industrial wastewater and discharged by a concentration tank by a physical method and physicochemical fine-grained sludge generated by a chemical method: belongs to fine-grained inorganic sludge, and has general compressibility and dehydration performance. Classifying the sludge generated by the treatment of the industrial wastewater through the physical and chemical precipitation and coarse-grained sludge treatment: belongs to coarse-grained hydrophobic inorganic sludge, and has good compressibility and dehydration performance.

In the past, sludge drying beds were the most commonly used sludge dewatering devices, and are particularly suitable for use in small sewage treatment plants due to their simplicity of operation and maintenance. About 2/3 sewage treatment plants use sludge drying beds, and the amount of dewatered sludge produced by the sludge drying beds is about half of the total amount of dewatered sludge. Although sludge drying beds are generally suitable for warm and sunny areas, there are also large-scale sewage treatment plants located in colder northern regions that employ sludge drying beds. The belt type sludge dewatering equipment is high-efficiency dewatering equipment, can carry out continuous filter pressing, and is a dewatering device with better sludge treatment capacity.

In the prior art, the dewatering effect of the sludge is not very good, especially for some sewage with a large water content, the effect is very limited if the drying method is only adopted, and the water after drying is difficult to preserve, which causes waste of water resource, on the other hand, the sludge is difficult to collect when filter pressing is carried out.
