Multielement organic matter mixed film-covering aerobic composting device and composting process thereof

Abstract

The invention discloses a multielement organic matter mixed film-covering aerobic composting device which comprises a fermentation bin, a plurality of frame rods, a plurality of telescopic rods, a semi-permeable film, a liquid collecting tank, a liquid collecting pipe, a spraying pipe, an air blower and an aeration pipe, wherein the frame rod is arched, and the frame rod is arranged at the top of the fermentation bin; the telescopic rods are arranged between the adjacent frame rods; the semi-permeable film is arranged above the frame rod; the liquid collecting tank is arranged underground outside the fermentation bin; one end of the liquid collecting pipe is arranged at the bottom of the fermentation bin, and the other end penetrates through the fermentation bin and is connected with the liquid collecting tank; one end of the spraying pipe is arranged at the top of the fermentation bin, and the other end penetrates through the fermentation bin and is connected with the liquid collecting tank; the air blower is arranged on the ground outside the fermentation bin; and one end of the aeration pipe is arranged at the bottom of the fermentation bin, and the other end penetrates through the fermentation bin and is connected with the air blower. The device is beneficial to heat preserving of the fermentation heap, does not influence biological decomposition of multielement organic matters, and has the advantages of preventing odor from escaping, reducing the occupied area, reducing the investment and operation cost and the like.

Description

technical field [0001] The invention relates to the technical field of organic matter composting, and more specifically relates to a multi-element organic compound film-covered aerobic composting device and a composting process thereof. Background technique [0002] With the development of society and the improvement of people's living standards, the output of organic waste is also increasing, and it is becoming more and more difficult to deal with it. [0003] Common organic wastes include kitchen waste, livestock and poultry manure and plant straw, etc. Among them, kitchen waste refers to the waste generated in the daily life of residents and activities such as food processing, catering services, and unit meals, including discarded vegetable leaves, leftovers, leftovers, fruit peels, eggshells, tea dregs, bones, etc. , and its main sources are home kitchens, restaurants, restaurants, canteens, markets and other industries related to food processing. Kitchen waste contain...

Problems solved by technology

But at the same time, the arched membrane easily allows the water vapor generated by the pile to leak out, resulting in a large amount of water loss in the pile, and a rapid decrease in the moisture content of the pile, which affects the activity of aerobic microorganisms, slows down the degradation of organic matter, and prolongs the composting time.
