Abstract

The invention discloses an anaerobic promoter and a method for processing solid wastes by the utilization of the anaerobic promoter. The anaerobic promoter of the present invention can effectively raise metabolic degradation speed of materials and enhance biogas cleaning degree. By the method, clean fuel gas and organic compound fertilizer can be prepared at the same time, and work efficiency is high. Through multiple experiments and data analysis, it is found that the anaerobic promoter can raise work efficiency of an anaerobic pond by 30-35%.

Description

technical field [0001] The invention belongs to the technical field of waste treatment, and in particular relates to a method for treating pan-solid waste by using an anaerobic accelerator. Background technique [0002] With the continuous development of my country's social economy and the rapid advancement of urbanization, more and more solid wastes are produced in production and life, and the types are complex. Arbitrary stacking of solid wastes will cause pathogenic bacteria, Harmful substances such as viruses, parasites, and heavy metals pollute the atmosphere, soil, and groundwater in the residential living environment, directly posing a threat to the physical and mental health of residents. We should also realize that: at present, landfill is still the main technology for solid waste treatment and disposal in my country, and the biogas released by landfill fermentation is far less than carbon dioxide emissions. The research on solid waste is still in its infancy, and it...
