PLANT FOR INDUSTRIAL TREATMENT OF DOMESTIC WASTE AND ORGANIC SLUDGE THROUGH THE RECYCLING OF UTILIZABLE PRODUCTS AND THE ACCELERATED PRODUCTION OF BIOGAS AND AN ORGANIC AMENDMENT (DIGESTATE) GENERATED BY THE MESOPHILIC ANAEROBIC FERMENTATION OF ORGANIC MATTER

摘要

The present invention relates to a profitable plant for treating household waste and fresh organic liquid sludge having less than eight (8) days. It works by respecting the rules of the environment and by producing recycled materials and energy in the form of BIOGAS which is composed of methane gas with a secondary chemical called carbon dioxide and an organic fertilizer called DIGESTAT. In the present invention, after sorting the materials to be recycled and in order to generate the maximum amount of biogas and digestate as quickly as possible, the fermentation is carried out by aerobic and anaerobic mesophilic bacteria which operate under optimal temperature and pH conditions. and the C / N ratio. The first part of the fermentation, which is acidogenic, takes place mainly in an aerobic fermentation tank called an acidogenic hydrolyser digester where the colonies of acidogenic bacteria proliferate. The second part of the fermentation, which is acetogenic, takes place in another sealed fermentation tank called anaerobic acetogenic secondary accelerator digester and comprising fixed contact surfaces where the colonies of acetogenic bacteria proliferate. The third part of the fermentation, which is methanogenic, takes place in another sealed fermentation tank called the tertiary anaerobic methanogenic accelerator digester similar to the second, and comprising fixed contact surfaces or proliferating colonies of methanogenic bacteria. The waste water is treated in a purification station before it is discharged outside or used in the factory.
