A new type of odorless organic waste composting system

Abstract

The invention relates to the technical field of organic waste treatment, in particular to a novel odorless organic waste composting treatment system, which includes an organic waste composting device, a biological filter device and a temperature linkage system. The organic waste composting device includes a jaw crusher, a garden waste composting Crusher, screw feeder, blower, gas heating furnace, leachate pool and organic waste composting tank, the biological filter device includes a filter box, a biological filter bed, an exhaust pipe and a draft pipe, and the temperature linkage system includes PLC programming controller, temperature control module, information analysis module, line energization control module, through the linkage of hot air and internal heat preservation system, the temperature stability of the device and the orderly progress of the fermentation reaction are realized, and the long-term effective, stable and efficient operation of the composting system is realized. , energy saving and consumption reduction, the organic waste composting tank is equipped with an air intake buffer layer and an odor gas collection layer to ensure that the entry and discharge of gas will not carry solid materials.

Description

technical field [0001] The invention relates to the technical field of organic waste treatment, in particular to a novel odorless organic waste composting treatment system. Background technique [0002] With the development of large-scale and facility-based agriculture in China and the improvement of people's living standards, a large amount of rotten organic waste is produced, such as livestock and poultry manure, leftovers, rotten vegetable leaves, agricultural straw, garden waste, etc. The amount of these wastes The increase has caused serious pollution to the environment. At present, a rapid and large-scale waste treatment system has gradually formed, such as landfill and incineration. The operating cost of the equipment required by the incineration method is huge, even exceeding the benefit of incinerating waste to collect heat. In addition, during the combustion process, with the generation of incineration ash, a large amount of harmful substances are discharged, caus...

Problems solved by technology

The operating cost of the equipment required by the incineration method is huge, even exceeding the benefits of incinerating waste to collect heat

In addition, during the combustion process, with the generation of incineration ash, a large amount of harmful substances are discharged, causing secondary pollution

The landfill method is a simple and easy method of garbage disposal, but due to the large land occupation area, there is less and less land available for landfill. In addition, biodegradable organic materials entering the landfill will produce waste due to decomposition. A large amount of harmful gas and leachate cause soil, water and air pollution. Composting of organic solid waste is a biological treatment method that integrates resource treatment and recycling. Its final product is organic fertilizer, which is used in agricultural production and is beneficial to The growth and development of crops, there are many evidences that the use of composting technology to treat organic solid waste has received more and more attention. However, there are many methods of biocomposting, most of which are directly composted in the workshop, which will produce a lot of stench , and the fermentation temperature should not be controlled, and the growth of microorganisms is blocked to a certain extent, which will affect the efficiency of composting and fertilizer efficiency. Therefore, a new type of odorless organic waste composting treatment system is needed to improve the above problems
