Sludge garbage chemical condition deep dewatering method and dewatering system thereof

Abstract

A sludge garbage chemical condition deep dewatering method comprises the following steps: the sludge after sewage treatment enters a sludge preconcentration tank, is conveyed to a sludge conditioningtank after concentration treatment, a condition catalyst is adopted in that sludge conditioning tank to carry out chemical reaction with the components contained in the sludge solution, as that internal structure of the sludge granule and the surface adsorption structure of the sludge granule cell are destroyed, internal bound water between sludge granule cells and sludge granule cells or on the surface of sludge granule cells is decomposed, the sludge slurry is formed, and then the sludge solution is extruded and deeply dewatered through a plate-frame diaphragm filter press, so that the moisture content of the dewatered sludge slurry cake is less than 50%, the moisture content of the dewatered sludge slurry cake is greatly reduced, and the reduction degree of sludge treatment is facilitated. As that sludge cake can be used to make organic fertilizer or biomass fuel for recycling, it is beneficial to protect the balance of natural ecological environment.

Description

【Technical field】 [0001] The invention relates to a deep dewatering method for chemical conditioning of sludge and waste used in the field of environmental protection and the dewatering system. 【Background technique】 [0002] With the increasing social population and more and more domestic waste generated by consumers every day, the disposal of domestic waste has become the most serious social problem. In order to solve the technical problem of dealing with domestic waste, various waste treatment methods have emerged, most of which are conventional extrusion, composting, incineration, and landfill treatment. In these treatment methods, due to the relatively high moisture content of the sludge and garbage itself, the moisture content of the treated sludge and garbage residues is basically above 80%. Buried treatment, the reduction degree is not high, it is easy to destroy the original environmental ecological balance, and the treatment cost is relatively high. [Content of ...

Problems solved by technology

In these treatment methods, due to the relatively high water content of the sludge waste itself, the water content of the treated sludge waste residue is basically above 80%. If the waste residue with more than 80% is burned or filled Buried treatment, the degree of reduction is not high, it is easy to destroy the ecological balance of the original environment, and the treatment cost is relatively high
