Abstract

The invention discloses a straw mixed raw material fermentation charging and discharging blocking resisting method. The method comprises the following steps: preprocessing straws, sending the preprocessed straws into a fermentation tank (1) through a forced charging and discharging system, carrying out biogas slurry self-stirring fermentation, and pumping out a fermented material from the fermentation tank (1) through the forced charging and discharging system. The preprocessing of the straws improves the gas yield, improves the CODcr concentration of a feed liquor, alleviates the crusting of straw mixed raw material fermentation floating residues, and substantially reduces the straw mixed raw material fermentation charging and discharging blocking risk. The forced discharging system adopting modular combination integration has the advantages of easy installation, simple operation, no need of grasping of professional technologies by users, instant grasping of the operation technology after simple training, convenient maintenance, low failure rate, good reliability, high safety, and complete avoiding of the straw mixed raw material fermentation charging and discharging blocking problem.

Description

technical field [0001] The invention relates to an anti-blocking method when straw mixed raw materials are used for fermentation in a biogas project. Background technique [0002] At present, most of the raw materials for biogas fermentation are single fecal raw materials for fermentation. The carbon content of fecal raw materials is large, and the fermentation raw materials cannot meet the requirements of the optimal carbon-nitrogen ratio (20-30:1) for biogas fermentation, resulting in low gas production rate. The anaerobic digestion reaction cannot proceed sufficiently. [0003] In view of the above problems, the carbon-nitrogen ratio is adjusted by adding raw materials such as straw and rice straw with high nitrogen content, so as to increase the gas production rate. At present, materials with high nitrogen content, such as straw and straw, are fed by cutting the straw or straw into particles smaller than 1cm through a rolling mill, and then pumping or entering from the ...
