Description

A sludge treatment system

technical field

The utility model belongs to the field of solid waste treatment equipment, in particular to a sludge treatment system.

Background technique

The large-scale projects supporting the domestic comprehensive textile dyeing and finishing industrial park include water supply plants, sewage plants, and thermal power plants, which jointly provide water, steam and electricity supply and sewage treatment services for the park. A large amount of sludge is produced in the production of water plants and sewage plants. Under normal circumstances, the sludge of the water supply plant and the sludge of the sewage treatment plant are separated, and they are transported to landfill, compost or incineration after each treatment reaches a certain moisture content requirement. Most of the sludge in the sewage plant is activated sludge with high organic content, which is suitable for resource utilization, but has a high water content and is difficult to dewater. Generally, it is necessary to add inorganic salt conditioners such as iron salt and lime for conditioning to reduce the moisture content. But at the same time, the addition of inorganic salts reduces the proportion of organic matter in the sludge, increases the corrosiveness to pipelines and equipment, and reduces its usable value. The sludge in the water supply plant is the sludge after coagulation and sedimentation, mostly physicochemical sludge, with relatively low water content and good sedimentation. The value of individual resource utilization is limited. The treatment of sludge generally adopts mechanical filter press, but the filter press equipment has low treatment efficiency and high moisture content after treatment, and the filter press has high requirements on the mechanical strength of the equipment and the pressure of the filter press.
