半透膜覆盖好氧堆肥技术应用现状综述

In recent years, membrane covered aerobic composting technology has been a research hotspot in organic matter aerobic treatment. It is mainly composed of membrane covered system, micro-pressure air supply system and control system. The film cover layer is composed of two layers of quality anti-ultraviolet cloth layer and one layer of polytetrafluoroethylene semi-permeable film, which has the advantages of water and air resistance. It can not only block the external environment and prevent the heap from being affected by rain and snow weather, but also reduce the volatilization of odor, so that the heap can reach the environmental conditions of closed fermentation. Membrane covering the aerobic composting technology were introduced in this paper the characteristics and advantages and disadvantages, this paper expounds the membrane covering the aerobic composting technology at home and abroad research progress and application of the status quo, analyzes the research in the field of membrane covering the aerobic composting technology deficiency, and points out the future should deepen the research on control of the process in composting process, and expand the application range of the film, used for livestock and poultry dung, eat hutch garbage and other organic waste disposal field.
