Sludge pressure filtration device for sewage treatment plant

Abstract

The invention discloses a sludge pressure filtration device for a sewage treatment plant, which structurally comprises foot mats, supporting legs, square tubes, a first motor, a shell, a drug box, a drug feeding opening, a feeding tank, a drying device, a sludge escape orifice and a drainage exit. The foot mats are vertically welded with the bottoms of the supporting legs; the tops of the supporting legs are vertically mounted at the bottom of the shell in a welding connection mode; the supporting legs are arranged on four corners of the shell; structurally, the shell is provided with a sewagereaction cavity, a sludge pressure cavity and a drying cavity; sewage firstly enters the sewage reaction cavity, bacteria solution in the drug box firstly carries out decomposition on bacteria in thesewage, the decomposed sewage enters the sludge pressure cavity, the sludge is subjected to dehydration treatment, the sludge after dehydration treatment is discharged into the drying cavity to be dried, so that residual pollutants in the sludge can be further treated, and damage of the sludge to the soil is prevented.

Description

Technical field [0001] The invention is a sludge filter press device of a sewage treatment plant, belonging to the field of sludge filter press devices of a sewage treatment plant. Background technique [0002] With the progress of industrialization and urbanization, the corresponding sewage and sludge production has also increased rapidly. At present, my country produces 40 million tons of sludge (water content 80%). It is estimated that by 2020, my country’s annual sludge production Over 60 million tons (80% moisture content), currently, the main destination of sludge produced in my country is landfills for landfill. With the continuous improvement of sewage treatment rate, the large amount of sludge produced will occupy a large amount of landfill sites. At the same time, suitable landfill sites are becoming more and more limited. Therefore, the treatment of sludge is a study of solid waste disposal. Hot spot. [0003] The prior art device directly performs simple and stable deh...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a sludge filter press device in a sewage treatment plant to solve the problem of simple and stable dehydration of the sludge in the prior art without further processing of the sludge. There are still hidden dangers of pollution in sludge, because after simple treatment, there are still pathogenic bacteria and other long-lasting organic pollutants in the sludge, which will cause harm to the soil
