Embodiment

[0035] Embodiment: a kind of municipal domestic sludge and straw heap rot treatment device, its structure is as follows figure 1 As shown, it includes a closed fermentation bin 7 with a sloping bottom. The upper part of the fermentation bin 7 has a material inlet. The material inlet is provided with a feed door 6, and the outside of the feed door 6 has a bacterial agent spray head 8. There is a material outlet at the lower part of the fermentation bin 7, and a discharge door 18 is arranged at the material outlet.

[0036] Feed gate 6 and discharge gate 18 all can be selected as electric control, to facilitate operation, and can improve the intelligent degree of this device.

[0037] The above-mentioned structure can make the material enter from the upper part of the fermentation bin 7, be evenly sprayed by the bacterial agent, then drop to the lower part for fermentation, and be discharged from the discharge door 18 after the fermentation is completed. Because the mixture has...

Abstract

The invention relates to a compost treatment device and method of city domestic sludge and straw and belongs to the technical field related to solid waste treatment and fermentation.The device mainly comprises a fermentation bin with an inclined bottom, the fermentation bin is provided with a material inlet and a material outlet, a feeding mechanism for feeding materials into the fermentation bin is arranged on one side of the fermentation bin, a discharge mechanism for outputting the materials is arranged on the other side of the fermentation bin, a heat transfer mechanism is further arranged outside the fermentation bin and on the same side of the feeding mechanism, the heat transfer mechanism transfers heat to the wall of the fermentation bin, a plurality of aeration pipes and water-replenishing sprayers are arranged inside the fermentation bin, and the mixture of the city domestic sludge and the straw at the bottom of the fermentation bin circulates with the mixture on the upper portion under the action of the aeration pipes so as to achieve compost fermentation without dead angle.By designing the the brand new structure, the device can perform synergic composite fermentation treatment on the city domestic sludge and the straw, and the problem that the city domestic sludge and the straw are hard to treat is solved.

Description

technical field [0001] The invention relates to the related technical field of solid waste treatment and fermentation, in particular to a device and method for treating municipal domestic sludge and straw heap rot. Background technique [0002] Municipal domestic sludge is the waste of municipal domestic sewage treatment plants, which is rich in trace elements and can be used as one of the main components of organic fertilizers. However, municipal domestic sludge has a high water content and contains a large number of harmful substances such as parasite eggs, pathogenic bacteria, and bacteria, so it cannot be directly spread on cultivated land as fertilizer. [0003] The harmless sludge treatment methods currently implemented mainly include drying, incineration and direct landfill. The above-mentioned several methods have relatively high treatment costs, and there is a certain degree of environmental pollution, so they do not meet the relevant requirements of environmental ...
