Problems solved by technology

Even if these measures are taken, the sites with sludge drying and incineration projects are still full of odor, which has become a bottleneck problem restricting the application prospects of sludge drying and incineration projects, which urgently needs to be solved
Moreover, a large number of odor-absorbing and deodorizing equipment purchased and arranged also increased the operating cost of the enterprise and seriously affected the economic benefits of the enterprise.

Abstract

The invention discloses a sludge comprehensive treatment system and method and belongs to the technical field of sludge treatment. The system comprises a sludge crushing, conveying and spraying device, a plant liquid conveying and spraying device, a fluidized bed sand particle removal and deodorizing device, a fluidized bed drying and cooling device and a tail gas treatment device. Through the sludge crushing, conveying and spraying device, sand particle-containing sludge forms liquid drops with sizes of 150-200 microns, the mixed liquid drops are uniformly sprayed into the fluidized bed sand particle removal and deodorizing device, and through adjustment of a fluidization air rate, sand particles with sizes of 200 microns or less are removed from wet sludge. The sludge comprehensive treatment system and method solve the problems that sludge with high sand content causes problems in a sludge anhydration burning system and equipment wear, reduces enterprise operation and maintenance costs, prevents odor in a region of the sludge anhydration burning engineering project, reduces capital investment of odor guidance and removal, realizes sludge continuous drying and has a good engineering application prospect.

Description

technical field [0001] The invention relates to a comprehensive sludge treatment system and method, and belongs to the technical field of sludge sand removal, deodorization and drying. Background technique [0002] Affected by factors such as large-scale construction and imperfect pipeline networks, the content of sand particles in urban sewage sludge in my country is generally high, and the distribution structure of sand particles is also significantly different from that of foreign countries. Although a large number of grit chamber systems have been introduced in recent years, the effect Not optimistic, most sewage treatment plants still have the problem of sand particles forming deposition in the subsequent treatment system. At present, the grit chamber system has a good removal effect on sand particles with a particle size greater than 200 μm, but the removal effect is not ideal for sand particles with a particle size of 100-200 μm, and the removal efficiency is very low ...
