Non-liquid fecal micro-oxygen storage system and method

Abstract

The invention relates to the field of organic solid waste disposal and resource utilization, and a non-liquid fecal micro-oxygen storage system is provided. The non-liquid fecal micro-oxygen storage system comprises a storage tank, wherein the storage tank is provided with a semi-permeable membrane and an aeration pipe line, the semi-permeable membrane covers the storage tank, air is charged intothe storage tank by the aeration pipe line, and an oxygen volume fraction formed in the storage tank is 4%-6% micro-oxygen environment. The invention also provides a non-liquid fecal micro-oxygen storage method, wherein the volume fraction of oxygen in the storage tank is set at 4%-6%, the aeration pipeline is arranged in that storage tank, and when the volume fraction of oxygen in the storage tank is less than 4%, air is charged into the storage tank by the aeration pipe line until the volume fraction of oxygen in the storage tank reaches 6%, and the aeration pipeline stops charging. The non-liquid fecal micro-oxygen storage system and method of the invention creates a micropressure and micro-oxygen environment, reduces the anaerobic area of the pile body, makes the fecal in a slow and stable fermentation state, and achieves the goals of energy saving, emission reduction, intelligent environmental protection, high quality and efficiency.

Description

technical field [0001] The invention relates to the field of organic solid waste disposal and resource utilization, in particular to a non-liquid manure micro-oxygen storage system and method. Background technique [0002] my country is a large country of livestock and poultry breeding. With the improvement of the production level of livestock and poultry breeding industry, the resource utilization of livestock and poultry manure has become an important factor restricting the development of my country's breeding industry. [0003] At present, intensive farms produce a large amount of feces, and they need to be stored in a centralized manner before resource utilization. However, most of the current farms have problems such as unreasonable construction of storage sites and too simple storage methods, which are not compatible with the rapid development of livestock and poultry farming in my country. There is a mismatch in the industry, and China has recently proposed the goal of...
