Problems solved by technology

During the fermentation process, not only will there be stench, the breeding of mosquitoes and other pests, but if the compost is not mature enough, the harm of secondary fermentation will occur in the soil; and the mixed substances with high carbon content will easily cause nitrogen deficiency and salt Concentration obstacles, and considerable harm to the growth of crops
At present, the equipment used for fermentation cannot guarantee full sealing, and will produce foul odor during operation, and the waste treatment cycle is relatively long, generally takes 5-7 days, and the efficiency is relatively low

Embodiment Construction

[0014] Put 60 kg of chicken manure into the raw meal pretreatment system 1, stir to remove sundries such as chicken feathers, ribbon-shaped sundries, etc. through the stirring claw, and use the screw pusher shaft of the raw meal elevator 2 to put the processed product into the reactor 4 The mixing chamber is ready for use; put 3 kg of active additive calcium oxide into the auxiliary material batching system 3, and put it into the mixing chamber through the screw pusher shaft for mixing and stirring, so that the oxygen in the air, calcium oxide, and waste are evenly mixed.

[0015] The exhaust gas generated in the stirring mixing reactor is sequentially introduced into two oxidation treatment devices 6 storing chlorine dioxide through the exhaust fan. The first device first performs deodorization and purification pretreatment, and the second device evolves the tail gas again, and finally The purified gas is vented to the atmosphere.

[0016] The stirred product is conveyed out ...

Abstract

The invention relates to a method and a device for treating corruptibility waste. The method comprises the following steps of mixing in proportion, stirring, deodorization, sterilization and dehumidification. The device comprises a raw material pretreating system, a raw material elevator, an auxiliary material burdening system, a reactor system and a belt conveyer, and is characterized in that a stirring claw of the raw material treating system is in a rod-shaped structure; the two spiral material pushing shafts, a left-handed rotation and a right-handed rotation are respectively arranged at two ends of a feeding hole of the raw material pretreating system; the raw material pretreating system is connected with the raw material elevator which adopts spiral elevating to feed the raw materials into the reactor system; the auxiliary material burdening system is connected with the raw material elevator to feed the auxiliary materials into the reactor system; and the discharge hole of the reactor system is connected with the belt conveyer. The invention has the following beneficial effects of high treating efficiency, and no secondary pollution; and the produced weak base organic fertilizer can improve soil activity.

Description

technical field [0001] The invention relates to a treatment method and device for spoilage waste. Background technique [0002] Corrosion waste refers to: poultry and livestock manure, river sludge, sludge and waste from food processing plants, oil tank sludge from breweries, tofu residues, biological sludge, pulp sludge, dairy processing sludge, animal fat etc. At present, the treatment method of spoilage waste used in our country is generally: closed composting fermentation method. During the fermentation process, not only will there be stench, the breeding of mosquitoes and other pests, but if the compost is not mature enough, the harm of secondary fermentation will occur in the soil; and the mixed substances with high carbon content will easily cause nitrogen deficiency and salt Concentration obstacles, and considerable harm to the growth of crops. At present, the equipment used for fermentation cannot guarantee full sealing, and will produce foul odor during the oper...
