Embodiment Construction

[0022] The present invention will be further explained below:

[0023] The present invention provides an anaerobic digestion method. The steps of the method are as follows:

[0024] (1) In an anaerobic environment, use the principle of negative pressure to lift the to-be-digested matter upward, and make the to-be-digested matter form a microbial film on the carrier of the vertical tank during the ascending process;

[0025] (2) After raising the ascending digestion to 6-8 meters, make it fall down, and set the microbial film-forming medium during the downward fall, so that it will continue to form a microbial film during the fall and fall ;

[0026] (3) Continue to lift the digested matter up and then down, each time it rises and falls into a set of digestion stages, repeat the digestion stages 7-8 groups and then discharge to complete the digestion process. The repeated ascent and falling process ensures the dynamic flow process of the to-be-digested substance, avoids the problems o...

Abstract

An anaerobic digestion method is characterized by comprising the following steps: (1) under an anaerobic environment, lifting the substances to be digested through a negative pressure principle, and forming a microbial membrane on the wall of a vertical tank during the lifting process; (2) when the substances are lifted to a height of 6 to 8 meters, making the substances fall down, and adding a microbial membrane forming medium during the falling process so as to keep on generating microbial membrane during the falling process; (3) keeping on lifting and lowering the substances to be digested, combining each lifting and lowering as one digestion grade, and repeating 7 to 8 digestion grades so as to complete the digestion. The provided anaerobic digestion method can improve the digestion efficiency.

Description

Technical field [0001] The invention relates to an anaerobic digestion method. Background technique [0002] Energy conservation and environmental protection have become the current mainstream awareness, and there is currently no good method for how to effectively dispose of human and animal feces and domestic waste waiting to be digested. Most of the current forms use single-stage treatment methods because of their simple operation, but The effect is very unsatisfactory. Summary of the invention [0003] Purpose of invention [0004] In view of the above problems, the present invention provides an anaerobic digestion method to solve the problem of unsatisfactory effects of the current method. [0005] Technical solutions [0006] An anaerobic digestion method is characterized in that the steps of the method are as follows: [0007] (1) In an anaerobic environment, use the principle of negative pressure to lift the to-be-digested matter upward, and make the to-be-digested matter form ...
