Problems solved by technology

This technology increases the pressure of sewage treatment while reducing the discharge of solid waste. Therefore, it fails to fundamentally solve the environmental pollution problem of kitchen food waste
Invention patent (Application No.: 01112685.X) discloses a biological treatment machine for organic waste, which uses special microbial flora to completely digest organic waste, but does not disclose the composition and preparation method of the microbial agent
Invention patent (application number: 02150972.7) discloses a domestic organic waste disposal machine using YB microbial functional bacteria. Assembly method
Due to the fact that the above-mentioned support materials such as twig chips, rice husks, cottonseed husks, and bamboo shoot husks are often subject to seasonal and regional restrictions, there are certain limitations in the popularization and application of microbial degradation and elimination technologies for food-source organic waste.

Abstract

The invention discloses a food-borne organic wastes degrading bacteria carrier. The carrier consists of the following components in percentage by weight: 0.1-10% of a dispersion material, 0.1-10% of a water-absorbent and a water-retaining material and the balance of an adsorption and supporting material. The dispersion material is a white carbon black having granularity of 20-1000 meshes, the water-absorbent and water-retaining material is polyacrylamide or potassium polyacrylate and the adsorption and supporting material is an organic fertilizer prepared by the fermentation and decomposition at high temperature of cattle manure and residue from mushroom culture, the water content of the organic fertilizer is less than and equal to 30%. The degradation capability of food-borne organic wastes is improved and the service time of the food-borne organic wastes degrading bacteria is prolonged by the food-borne organic wastes degrading bacteria used in conjunction with the carrier.

Description

technical field [0001] The invention belongs to the field of domestic waste treatment, and relates to a microbial degradation and elimination technology for food-source organic waste, in particular to a carrier of a microbial bacteria-reducing agent for food-source organic waste. Background technique [0002] With the rapid development of my country's social economy, not only the amount of household garbage of urban residents is increasing, but also the proportion of food-source organic garbage including melon peels and shells, leftovers and leftovers in household garbage is also increasing. Due to the high water content (90%) and low incineration calorific value (2100-3100kJ / kg) of food-source organic waste, after being mixed with other urban waste components, landfill disposal will not only occupy valuable land resources but also produce a large amount of leachate. Pollution of underground water system; use of incineration for power generation disposal can not meet the cal...
