NOVELTY - Processing organic garbage anaerobic digestion comprises: (1) removing large kitchen garbage plastic bag and big block sundries metal tool; (2) kitchen garbage lifting and pouring the roughly selected from the kitchen waste into the hopper, a lifting and pouring into mechanical biochemical reaction device by lifting device; (3) a hydrolysis acidification; (4) thin separating the leaching filtrate; (5) an oil-water separating the filtrate of bar rotary drum filter; and (6) an anaerobic digestion.    USE - The method is useful for processing organic garbage anaerobic digestion (claimed).    ADVANTAGE - The method has reasonable technique and can improve the organic component hydrolysis and acidification rate, can reduce the residual organic component content, and can reduce processing cost.    DETAILED DESCRIPTION - Processing organic garbage anaerobic digestion comprises: (1) removing large kitchen garbage plastic bag and big block sundries metal tool; (2) kitchen garbage lifting and pouring the roughly selected from the kitchen waste into the hopper, a lifting and pouring into mechanical biochemical reaction device by lifting device; (3) a hydrolysis acidification the stirring propeller mechanical biochemical reaction device for stirring the kitchen garbage, at the same time spraying flow adjustable kitchen waste washing water, the organic component in the kitchen waste processing hydrolysis acidification reaction and dissolving the leaching filtrate under the action of mechanical stirring and washing water, where the hydrolysis acidification temperature is 30 degrees C and -40 degrees C and the time is controlled at 70-80 hours; (4) thin separating the leaching filtrate then enter into rotary drum grid through drum bar and carrying out solid liquid separation, separating sieve pore diameter of the drum grill machine is controlled. 0.4 to 0. 8%, the fine slag after fine filter by pressing conveyor into the container, and the container periodically into the releaching and stirring machine biochemical reaction device by the lifting device; (5) an oil-water separating the filtrate of bar rotary drum filter; and (6) an anaerobic digestion.
