Treatment method for realizing rapid resource treatment and zero emission of vegetable waste

Abstract

The invention relates to a treatment method for realizing rapid resource treatment and zero emission of vegetable wastes. The treatment method comprises the following steps of: 1) after mud and sand on the surfaces of the vegetable wastes are removed, using air-water mixture to clean the vegetable wastes, draining and dehydrating; 2) crushing the vegetable wastes with the mud and sand being removed in the step 1 under the condition of high-speed rotation; 3) adding alkaline materials into the crushed and pulped vegetable wastes with cell walls being broken in the step 2 to regulate the pH value to 8-9, and leaching leaf proteins; 4) conducting solid-liquid separation to the slurry with the leaf proteins being leached in the step 3; 5) filtering and concentrating the alkaline leaf protein solution obtained in the step 4 and drying to make into leaf protein feed additives; and 6) conducting chemical and catalytic hydrolysis reaction and culture fermentation to the deproteinated vegetable residues obtained in the step 4, mechanically breaking walls, drying and dehydrating, adjusting nutrients, adding functional microbes and additives, metering and packaging to obtain compound microbial fertilizers.

Description

technical field [0001] The invention relates to a treatment method for solid waste, and more specifically, relates to a treatment method for rapid resource recovery and zero discharge of vegetable waste. technical background [0002] With the acceleration of urbanization, the growing economy, the gradual improvement of people's living standards, the gradual increase in the consumption of vegetables in cities, the public's higher and higher hygienic requirements for clean vegetables, vegetables grown in rural areas, need clean vegetables to go on the market, and a large number of discarded vegetable leaves are left behind. Vegetable sides, vegetable roots and rotten and yellowing parts, further cleaning of vegetables in urban vegetable markets also produces a large number of discarded vegetable leaves, vegetable sides, vegetable roots and rotten and yellowing parts, so the waste after cleaning vegetables in rural and urban areas is increasing, which has already affected the en...
