Municipal sludge treatment device and treatment method thereof

Abstract

The invention discloses a municipal sludge treatment device and a treatment method thereof. The municipal sludge treatment device comprises a box body, wherein a motor is fixedly connected to the topof the box body; a rotary shaft is fixedly connected to an output shaft of the motor; the bottom end of the rotary shaft extends into the box body; a plurality of stirring blades are welded to the outer side of the rotary shaft; connecting pipes are fixedly connected to both sides of the box body; the same air box is connected to the top ends of the two connecting pipes; the air box is fixedly mounted on one side of the top of the box body; an air pump is fixedly connected to the top of the air box; an air outlet of the air pump extends into the air box; a plurality of first heating rods arranged horizontally are fixedly connected to the inner wall of the air box; a liquid injection hole is formed in one side of the top of the air box; and a first plug is mounted in the liquid injection hole in a threaded manner. The device is reasonable in design, can fully stir sludge in the box, enables a microbial stock solution to be fully mixed into the sludge, so that the organic matter contentin the sludge is decreased; and in addition, the device can dry the sludge, and the drying efficiency is high.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a municipal sludge treatment device and a treatment method thereof. Background technique [0002] At present, with the continuous development of science and technology, the progress of the times, and the continuous improvement of people's living standards, people have higher and higher requirements for municipal sludge treatment; sludge contains a large amount of organic matter and rich nitrogen, phosphorus, etc. Nutrients, causing eutrophication of water quality, leading to deterioration of water quality, especially urban sludge contains about 70% organic matter, these organic matter enters the water body, will cause water pollution and water quality eutrophication, for example, the application number is 201810297836.0 The patent document discloses a municipal sludge treatment device, which includes a barrel body with an opening at the upper end. The upper end of the ba...

Problems solved by technology

[0003] However, the existing municipal sludge treatment device is inconvenient to fully mix the microbial stock solution with the sludge, the mixing degree is low, and it is inconvenient to dry the sludge, and the sludge treatment efficiency is relatively low, so we propose a municipal sludge treatment device and its processing methods are used to solve the above problems
