Problems solved by technology

[0007] However, in the prior art, there are no reports and documents on the simultaneous use of sludge, edible fungus waste culture substrates and landscaping wastes to prepare fuels. Starting from this point, the inventors of this case aim to solve the problem of sludge and edible fungus waste culture substrates and landscaping wastes. The problem of greening waste disposal, and using these wastes to prepare solid fuels with high calorific value and easy molding, this case arose from this

[0022] Pretreatment and preparation of starch glue:

[0023] (1) Pretreatment: the moisture content of the waste culture substrate of edible fungi should be controlled within 30%, and the particle size should be controlled within 1~4mm; the sludge is organic water-containing sludge from a sewage treatment plant, and a small amount of quicklime is added to dehydrate and remove it. Bacteria and impurities are removed, and the moisture content is controlled within 30%; the moisture content of landscaping waste is controlled within 15%, and the particle size needs to be controlled within 1~4mm.

[0024] (2) Preparation of starch glue: by weight percentage, tapioca starch 30-40% and water 50-60%, stir and mix at 75°C-80°C, add 0.5-1% CaCl 2 and 5-8% α-amylase, stir evenly, return the temperature to 55°C-60°C, add 3-5% boric acid and stir evenly. Using this method to prepare starch glue, the process is relatively simple, the additives are few, and the starch glue produced has high ...

Embodiment 1

[0026] Mix 30% of the above-mentioned pretreated edible fungus waste culture substrate, 20% of sludge and 30% of landscaping waste, and then add 12% of waste oil and 8% of the starch glue prepared above to mix; send the mixed materials to The solid fuel can be obtained by putting it into a press machine; the prepared solid fuel is passed through a vibrating screen machine to remove broken materials, and then sealed and bagged. The solid fuel pressed according to the above method has good molding effect and high calorific value, and can be pressed into block, rod and granular solid fuel according to different types of press machines.

Embodiment 2

[0028] Mix 30% of the above-mentioned pretreated edible fungus waste culture substrate, 20% of sludge and 35% of landscaping waste, add 10% of waste oil and 5% of the starch glue prepared above; send the mixed materials to The solid fuel can be obtained by putting it into a press machine; the prepared solid fuel is passed through a vibrating screen machine to remove broken materials, and then sealed and bagged.

Abstract

The invention discloses edible mushroom waste culture medium and landscaping waste and sludge mixed solid fuel which is prepared by the following steps: mixing and pressing the following components: 30-40 percent of an edible mushroom waste culture medium, 20-30 percent of sludge, 25-35 percent of landscaping wastes, 8-16 percent of waste oil and 4-12 percent of starch glue, thereby obtaining the solid fuel. According to the solid fuel disclosed by the invention, the treatment problem of the edible mushroom waste culture medium, landscaping wastes and organic matter sludge is solved, and the edible mushroom waste culture medium and landscaping waste and sludge mixed solid fuel pressed by the method has the characteristics of high heating value and good molding effect.

Description

technical field [0001] The invention relates to a solid fuel mixed with edible fungus waste culture substrate, landscaping waste and sludge and its processing technology, which belongs to the technical field of solid waste treatment and disposal and solid fuel preparation. Background technique [0002] In my country, the issue of sewage treatment has been paid more and more attention, and the volume and rate of sewage treatment have been increasing year by year. What followed was a lot of sludge. Sludge is a by-product of sewage treatment. At present, the main treatment methods are landfill and incineration. In the case of shortage of land resources, landfill treatment is not conducive to the development of ecological cities, and has the hazard of polluting groundwater. At present, it has been gradually replaced by incineration treatment. The incineration treatment efficiency is high, and the sludge itself has a certain calorific value, so the incineration treatment can be...
