A sludge treatment device

Abstract

The invention discloses a sludge treatment device, which belongs to the technical field of sludge treatment. The technical scheme of the present invention is: a sludge treatment device, comprising a machine base, a sludge treatment drum, a power drive mechanism, an output pipeline and a hood, the special feature of which is that the sludge treatment device includes at least heavy metals The treatment drum, the carbonization drum and the fixed carbon combustion drum consist of three coaxial sleeves from the inside to the outside. Compared with the prior art, the present invention is a new sludge treatment with reliable technical scheme, no secondary pollution, high investment efficiency and quick effect. The device is with outstanding substantive features and remarkable progress.

Description

technical field

[0001] The invention relates to the technical fields of chemical industry and environmental protection, in particular to the technical field of a sludge treatment device used for sludge, especially for urban sewage treatment plants. Background technique

[0002] In recent years, with the rapid improvement of my country's sewage treatment capacity, the amount of sludge has also increased significantly. As of the end of March 2013, as far as sludge from urban sewage treatment plants is concerned, a total of 3,451 urban sewage treatment plants have been built in cities and counties across the country, with a sewage treatment capacity of about 145 million cubic meters per day, and annual production of sewage with a water content of 80%. There are more than 35 million tons of sludge, and there are about 120 sewage treatment plants increasing each year. According to statistics, about 80% of sewage plants have sludge concentration and dehydration facilities, which ...
