Method and device for improving yield of CH4 with high intrinsic waste content and control rate of H2S
The invention provides a method and a device for improving the yield of CH4 and the control rate of H2S of high-content intrinsic waste. The method comprises the following steps that high-content inherent organic waste with the solid content being 10-30% is added into a reactor in a semi-continuous...

| description | The invention provides a method and a device for improving the yield of CH4 and the control rate of H2S of high-content intrinsic waste. The method comprises the following steps that high-content inherent organic waste with the solid content being 10-30% is added into a reactor in a semi-continuous fermentation mode, air is evenly input into the bottom of a fermentation tank through a micropore aeration head, 0.5-6 mL of air is needed for 1 g of dry basis organic matter, and the air is mixed with fermentation materials in a microbubble mode; and respectively collecting biogas and residues generated by fermentation. The principle of the application is as follows: trace air improves the microbial hydrolysis capacity of refractory organic matters such as cellulose, does not inhibit the activity of CH4-producing bacteria, improves the H2S oxidation capacity of microorganisms, and finally improves the CH4 yield and H2S removal rate of the raw material.
