Method and device for collaborative treatment of feces in waste incineration plant

Abstract

The invention provides a method and device for collaborative treatment of feces in a waste incineration plant. The method comprises the following steps of filtering the feces through a grid to form fecal residues and fecal liquid; conveying the separated fecal residues to a garbage bin for incineration together with garbage in the garbage bin; conveying the separated fecal liquid to a fecal liquidregulating pool; conveying the fecal liquid to a percolate treatment station for treatment to generate treatment water and concentrated water; and conveying the treated water to a waste incinerationtreatment system in the waste incineration plant for recycling, wherein the amount of the fecal liquid entering the percolate treatment station is regulated by the fecal liquid regulating pool. According to the method and device for collaborative treatment of the feces in the waste incineration plant, the collaborative treatment of the feces can be achieved in the waste incineration plant, so thatthe harmless and resource-based treatment of the feces is achieved, and the investment and operation cost is reduced.

Description

technical field [0001] The invention relates to waste treatment and utilization technology, in particular to a method and device for collaborative treatment of waste incineration plants. Background technique [0002] With the acceleration of urbanization and the continuous increase of urban population, the amount of excrement produced is also increasing. If the feces removed from septic tanks and public toilets are not harmlessly treated, they will definitely cause certain environmental pollution and affect the lives and health of residents. [0003] In the current treatment scheme, fecal wastewater enters the solid-liquid separation system through the excrement discharge port, removes solid matter (fecal residue) and sends it to the landfill for treatment, and the wastewater after solid-liquid separation is sent to the fecal wastewater adjustment tank , and then mixed with landfill leachate in a certain proportion. The treated drainage can be discharged nearby or used for...

AI Technical Summary

Problems solved by technology

This scheme has the following disadvantages: 1. Landfilling solids not only increases the treatment cost, but also wastes land resources; 2. The recharge of concentrated water to the landfill will cause the continuous accumulation of salt in the landfill, which will be unfavorable for biological treatment in the long run The operation of the system will reduce the desalination rate of reverse osmosis; third, this scheme will easily cause air pollution if the odor is not properly treated; fourth, the sewage discharge index is low, and it is increasingly difficult to meet strict environmental protection requirements
