Municipal sludge treatment device

Abstract

The invention discloses a municipal sludge treatment device which comprises a barrel body with the upper end provided with an opening. The upper end of the barrel body is rotatably connected with a barrel cover, the side wall of the barrel cover is provided with a locking device, a fixed plate is arranged in the barrel body, the two ends of the fixed plate are fixedly connected with the opposite side walls of the barrel body respectively, the upper end of the fixed plate is provided with a hollow sliding groove in a through mode, a scattering disc is arranged in the hollow sliding groove and movably connected with the inner wall of the hollow sliding groove, the inner top of the barrel body is fixedly connected with an installing frame, the lower end of the installing frame is fixedly connected with a second driving motor, the tail end of an output shaft of the second driving motor is fixedly connected with a rotating disc, and one end of the rotating disc far away from the second driving motor is fixedly connected with a rotating shaft. The municipal sludge treatment device is reasonable in structural design and simple to operate, a microbial stock solution is quickly and uniformly diffused into sludge, the microbial digestion rate is improved, and the amount of the microbial stock solution used is small, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of sludge treatment equipment, in particular to a municipal sludge treatment device. 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, lead to deterioration of water quality, especially urban sludge contains about 70% organic matter, these organic matter enters the water body, will cause water body pollution and water quality eutrophication, if only landfill will cause other The COD and BOD in the filtrate have increased significantly, so microbial digestion will be used for treatment. In this method, the diffusion speed of microorganisms in the sludge is slow, so...

Problems solved by technology

[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, lead to deterioration of water quality, especially urban sludge contains about 70% organic matter, these organic matter enters the water body, will cause water body pollution and water quality eutrophication, if only landfill will cause other The COD and BOD in the filtrate have increased significantly, so microbial digestion will be used for treatment. In this method, the diffusion speed of microorganisms in the sludge is slow, so the processing speed is slow, so we need a new one. equipment to solve problems
