Abstract

The invention relates to a stem and a method used for pretreatment of penetrating fluid before entering into regulating tanks in solid waste treatment plants. The system comprises a solid impurity filtering tank and a flocculation and sedimentation device; the solid impurity filtering tank is connected with the flocculation and sedimentation device via a material blender; the material blender is provided with a raw water inlet pipe, a processed water inlet pipe, and a mixed material water outlet pipe; the raw material inlet pipe is connected with a water outlet of the solid impurity filtering tank; the flocculation and sedimentation device comprises a flocculation mechanism, a cooling mechanism, a sedimentation mechanism, and a microfloc collecting mechanism which are connected successively. The system and the method are used for processing penetrating fluid, pretreatment efficiency is increased greatly; after pretreatment, heavy metal in the penetrating fluid is reduced obviously, COD content is reduced greatly, the biodegradability of the penetrating fluid is increased, and favorable conditions are provided for subsequent sludge biological treatment.

Description

technical field [0001] The invention relates to the technical field of solid waste permeate treatment, in particular to a pretreatment system and treatment method before the permeate enters a regulating tank in a solid waste treatment plant. Background technique [0002] With the rapid development of society and the improvement of living standards, the output of urban solid waste is increasing, and the disposal of solid waste has become an urgent task. Urban solid waste is growing at an average annual rate of 8%-10%. Domestic solid waste occupies a large amount of land, seriously damages urban environmental sanitation, and deteriorates living conditions. Urban domestic solid waste has become a very prominent urban environmental problem and hinders urban construction. develop. Therefore, domestic solid waste disposal has become an unavoidable worldwide problem in urban management. There are many methods of municipal solid waste treatment, such as sanitary landfill, composti...
