Municipal sludge treatment device

Abstract

The invention discloses a municipal sludge treatment device, which structurally comprises an oil scraping device, an ascending and descending table, a support post, a storage box, a funnel, a supportframe, a treatment chamber, a connecting pipe, a chemical adding box and a controller, wherein the chemical adding box is fixed at the upper side of the connecting pipe through screws; the oil scraping device is provided with a sludge transporting device, a fixing balancing device, a pulling triggering device, a double-side driving device, a rope recovery device, a collection recovery device, an oil stain collecting device and an outer casing. The municipal sludge treatment device has the beneficial effects that through the addition of the oil scraping device, during the sludge treatment at the inside, oil layers at the upper surface layers of sludge can be scraped and are then collected, so that the crude oil recovery rate is high; the water content and the oil content of the finally treated sludge are small, so that the goal of recovering the crude oil is achieved; the sludge treatment is more thorough; the sludge subjected to oil scraping treatment can be relatively safely discharged; the phenomenon of secondary pollution cannot be caused; the discharging safety is improved.

Description

technical field [0001] The invention relates to a municipal sludge treatment device, which belongs to the field of sludge treatment devices. Background technique [0002] Sludge treatment is the process of sludge reduction, stabilization and harmless treatment. The higher the degree of sewage treatment, the more sludge residues will be generated to be treated, unless land treatment or sewage ponds are used Sewage treatment, otherwise general sewage treatment plants must be equipped with sludge treatment facilities. For modern sewage treatment plants, sludge treatment and disposal have become the most complicated and costly part of the sewage treatment system. Current technology A public municipal sludge treatment device will produce a large amount of oily sludge during treatment. The treatment of oily sludge is relatively difficult, and it is difficult to treat the oil-bearing layer and directly use it for reinjection and circulation in the sludge treatment system. At the s...

AI Technical Summary

Problems solved by technology

[0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a treatment device for municipal sludge to solve the problem that a large amount of oily sludge will be generated when the treatment device for municipal sludge commonly used in the current technology is processed. It is difficult to treat the oil-bearing layer. When it is directly used for reinjection and circulation in the sludge treatment system, it will cause the quality of injection water to decline and the operating conditions of the sludge treatment system to deteriorate, causing unpredictable losses to production. At the same time, a large amount of oil resources are wasted, and it is not conducive to the discharge of sludge after treatment.
