Embodiment 1

[0033] refer to Figure 1-Figure 5, a sludge harmless treatment device, comprising a bottom plate 1, a support frame 2 is fixed on the bottom of the bottom plate 1 by bolts, a feed adjustment mechanism is provided on one side of the bottom plate 1, and a fixed plate 4 is fixed on the upper surface of the bottom plate 1 by bolts , and the upper surface of the fixed plate 4 is fixed with two fixed frames 5 by bolts, and one side of the fixed frame 5 is fixed with a servo motor 6 by bolts, and a sludge treatment mechanism is connected between the two fixed frames 5, and the sludge treatment mechanism The setting can kill harmful substances and insect eggs in the sludge by heating at high temperature, and can also evaporate excess water in the sludge. The sludge treatment mechanism includes the outer cylinder 7 and the inner cylinder 704, and one side of the inner cylinder 704 is integrally formed There is a sliding ring 705, and the sliding ring 705 is slidingly connected with th...

Embodiment 2

[0037] refer to Figure 6-Figure 7 , a sludge harmless treatment device, one side of the support frame 2 is fixed with a second slideway 1602 by bolts, and one side of the second slideway 1602 is slidably connected with a slide rail 1601, and the slide rails 1601 are all fixed by bolts There is the same fermentation tank 16, and the fermentation tank 16 that can be pulled is set, which abandons the disadvantages of the traditional fermentation tank being inconvenient to move, and is more convenient for post-composting treatment. It has certain innovations and improves the efficiency of composting to a large extent. In order to improve the efficiency of sludge harmless treatment, one side of the fermentation tank 16 is fixed with a hinge by bolts, and the other side of the hinge is fixed with a discharge door 1603 by bolts.

[0038] The present invention also includes a method of fermenting sludge into fertilizer, the specific method is as follows:

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a sludge harmless treatment device. Background technique [0002] As we all know, municipal sludge refers to the solid waste generated during the treatment of urban domestic sewage and industrial wastewater. Sludge contains toxic and harmful substances such as heavy metals, pathogenic bacteria, and parasite eggs. With the development of urban industry and economy, the amount of sludge has increased sharply. Improper disposal may cause serious damage to the ecological environment and human health. How to treat sewage The use of sludge becomes the top priority. There are many existing sludge treatment methods. The harmless methods include anaerobic digestion, aerobic digestion, sludge composting, heat treatment, biological leaching, etc., using sludge composting The most cost-effective method is the method with a relatively high utilization rate. [0003] At present, mos...
