Problems solved by technology
[0002] In sewage treatment, it is often necessary to undergo sedimentation treatment, that is, the solid matter in the sewage is precipitated to form sludge, and then the precipitated sludge is dehydrated to form solid sludge, but because the sludge contains more microorganisms Bacteria and micelles lead to high volatile solid content and high specific resistance in the sludge, resulting in difficult dehydration and incomplete dehydration, which increases the difficulty of subsequent sludge treatment

The present invention discloses a residual sludge reduction system which comprises a sludge storage tank, the sludge outlet end of the sludge storage tank is connected with a sludge pump, and the rear end of the sludge pump is provided with a crushing part and a dewatering part; the crushing part comprises a circulating pipeline communicated with the sludge pump, the circulating pipeline is connected with a wall breaking device for breaking walls of the sludge, and the other end of the circulating pipeline is communicated with the sludge storage tank; the dewatering part comprises a dewatering pipeline communicated with the sludge pump, and one end, away from the sludge pump, of the dewatering pipeline is connected with a sludge dewatering device. The wall breaking device is circularly connected with the sludge storage tank, wall breaking treatment can be carried out on sludge in the sludge storage tank through wall breaking blades in the wall breaking device, through multiple times of circular treatment, microorganisms and colloid can be effectively subjected to wall-breaking crushing, the clotting state of the sludge is destroyed, the sludge is dispersed, the hydrophilic performance of the sludge is greatly reduced, the dewatering degree and quality of the sludge are improved, the water content of the sludge and the usage amount of conditioning agents are reduced, the sludge yield is reduced, and the purpose of sludge reduction is achieved.
Description
technical field [0001] The invention relates to the technical field of sludge treatment equipment, in particular to an excess sludge reduction system. Background technique [0002] In sewage treatment, it is often necessary to undergo sedimentation treatment, that is, the solid matter in the sewage is precipitated to form sludge, and then the precipitated sludge is dehydrated to form solid sludge, but because the sludge contains more microorganisms And bacterial micelles, so that the volatile solid content in the sludge is high, and the specific resistance value is large, resulting in difficult dehydration, incomplete dehydration, and increased difficulty in subsequent sludge treatment. Contents of the invention [0003] The purpose of the present invention is to provide an excess sludge reduction system to solve the problems raised in the above-mentioned background technology. [0004] To achieve the above object, the present invention provides the following technical so...
