Kitchen waste aerobic fermentation equipment and waste treatment method thereof

Abstract

The invention relates to kitchen waste aerobic fermentation equipment comprising a frame, a fermentation bin, an aeration system, a leachate collection system, a sample collection and online monitoring system and an electrical control system; a feeding port and a discharging port are formed in the fermentation bin, a heating and heat preservation system is arranged outside the fermentation bin, astirring system is arranged in the fermentation bin, and the aeration system and the leachate collection system are arranged at the bottom of the fermentation bin; the sample collection and online monitoring system comprises a solid sample collecting device and a gas sample online measuring device, the solid sample collecting device is arranged on the side edge of the fermentation bin, a gas outlet pipeline is arranged at the upper part of the fermentation bin, and the gas sample online measuring device is arranged in the gas outlet pipeline; and the electrical control system can electricallycontrol the aeration system, the stirring system and the heating and heat preservation system. The equipment disclosed by the invention is simple in structure and convenient to use, and can solve theproblems of long fermentation period, high labor intensity and unstable fertilizer quality in traditional natural fermentation, and the problems of high-temperature composting machine that it is impossible to reach composting standards and waste returning to field is impossible to realize.

Description

technical field [0001] The invention relates to the technical field of kitchen waste treatment, in particular to an aerobic fermentation equipment for kitchen waste and a waste treatment method thereof. Background technique [0002] With the acceleration of urbanization and the continuous improvement of people's living standards, the production of urban domestic waste is increasing every year. The resulting waste disposal challenges are becoming increasingly severe, and the phenomenon of "garbage siege" is becoming more and more prominent. Kitchen waste accounts for nearly half of domestic waste, and because of its high humidity (60%-80%), high organic matter content (volatile solids / total solids content is 74.6%-95.3%), high nutritional element content (protein content It is 1.4-38.9% of the total solid content, carbohydrates account for 0.8%-59.9%, lipids account for 0.1%-41.5%) and other characteristics, and are extremely easy to deteriorate and rot during storage, transp...
