Problems solved by technology

[0006] However, because ammonia, nitrous oxide, carbon dioxide, and low-carbon alkanes are smaller than the micropore diameter of the membrane, they will still diffuse out of the membrane under the action of pressure difference. For example, in the composting process, only more than 90% of the deodorization can be achieved. In the technology, it is mainly for environmental protection control gases (such as ammonia gas), mainly through hydrophilic treatment on the inner side of the membrane, so that water vapor can accumulate on the non-pore parts to form water, and use the characteristics of ammonia gas that is easily soluble in water , with the water dripping back onto the stockpile, and being further fixed in the fermentation material by microorganisms, but this process will be affected by many factors, and at the same time non-water-soluble greenhouse gases such as nitrous oxide and low-carbon alkanes will be discharged out of the membrane ( The emission reduction effect is only above 50%). On the one hand, resource waste (wasting nutrients, carbon, etc.), on the other hand, the deodorization and emission reduction effects are limited
Moreover, when film-covered fermentation is carried out, the temperature and humidity distribution in the fermentation chamber is uneven, the fermentation is insufficient, and the fermentation effect is poor.

Abstract

The invention relates to the technical field of circulation in organic solid waste fermentation treatment, in particular to a film-covered aerobic fermentation circulation device and a circulation method. Including fan, the fan is connected to several fermentation bins, the air inlet of each fermentation bin is connected to the fan through the air supply pipe, and the air outlet of each fermentation bin is connected to the fan through the exhaust pipe; There is an automatic monitoring unit, and the automatic monitoring unit and the fan are connected with the automatic control unit; the top of the pile in the fermentation bin is covered with a waterproof and moisture-permeable film. The device can adjust the temperature and humidity in the fermentation bin and the distribution of oxygen concentration between the piles, so that the fermentation bin can fully circulate inside and outside, so that the fermentation is sufficient and the fermentation effect is good. The circulation method carried out by this device can not only make the interior of the fermentation chamber ferment evenly, but also provide other fermentation chambers with the oxygen and temperature required for the initial fermentation reaction, promote the fermentation reaction, increase the overall efficiency, improve the carbon fixation rate, and reduce greenhouse gases emission.

Description

A kind of membrane covered aerobic fermentation circulation device and circulation method technical field The present invention relates to the recycling technical field of organic solid waste fermentation process, especially relate to a kind of membrane covering aerobic fermentation Circulation device and circulation method. Background technique The state attaches great importance to the construction of ecological civilization, with the rapid development of my country's industry and agriculture, livestock and poultry manure, straw, garden waste Organic solid wastes such as garbage and traditional Chinese medicine residues have not been properly treated, causing harm to the ecological environment. How to process efficiently, quickly and at low cost The utilization of organic solid waste and resource utilization has become a research hotspot in the ecological and environmental protection industry. Among them, the nano-film covered high-temperature aerobic fermentation ...
