摘要： The present invention provides a method of enhancing continuous directional high-value biological conversion of an urban wet garbage open system. The method includes wet garbage crushing, low-energy consumption hydrolysis, continuous conversion of organic components of wet garbage into short-chain fatty acid, continuous directional conversion of other components of short-chain fatty acid into acetic acid, separation and microbial reflux of acetic acid, and the like. In this method, by crushing wet garbage, performing low-energy consumption hydrolysis, and seeding acclimatized activated sludge, two stages of anaerobic fermentations are carried out to firstly convert organic components of the wet garbage continuously into short-chain fatty acid, and then continuously and directionally convert other components of short-chain fatty acid into acetic acid, so as to realize continuous directional high-value biological conversion of the urban wet garbage in an open system without adding pure microbes and a large amount of chemicals.
