Problems solved by technology

Since the focus of the existing invention is how to improve the adsorption capacity of the carrier material to the functional microorganisms and the survival rate of the functional microorganisms in the bacterial agent, these carriers do not meet the requirement that the garbage-degrading bacterial agent must have good air permeability, water absorption and water holding properties for the carrier. Requirements for resistance to microbial decomposition

Abstract

The invention discloses a perishable organic garbage degrading bactericide carrier. The carrier consists of the following components in percentage by weight: 60 to 89.9 percent of support material, 10 to 35 percent of adsorption material and 0.1 to 20 percent of water absorption and waterholding material. The support material is plant shells or scraps with looseness, porosity and strong air permeability; the adsorption material is a material with high adsorption property and strong water absorption property for garbage degrading functional bacteria; and the water absorption and waterholding material is high water-absorbing resin. The carrier has the functions of support, adsorption and water retention at the same time. When perishable organic garbage degrading bactericide is used with the carrier, the carrier can improve the perishable organic garbage degrading capability and prolong the running time of a perishable organic garbage degrading system.

Description

technical field [0001] The invention belongs to the field of domestic waste treatment, and relates to a microbial degradation and elimination technology for perishable organic waste, in particular to a carrier of a microbial fungicide for perishable organic waste. Background technique [0002] With the rapid development of my country's social economy, not only the amount of domestic waste of urban residents is increasing, but also the proportion of perishable organic waste such as melon peel and shell, leftovers and leftovers in domestic waste is also increasing. Due to the high moisture content (90%) and low incineration calorific value (2100-3100kJ / kg) of perishable domestic 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 And pollute the groundwater system; the use of incineration power generation disposal can not meet the calorific value requirements of g...
