Abstract

The present invention belongs to the technical field of garbage treatments and particularly relates to a preparation method and an application of an ultrahigh-temperature aerobic composite biologicalbacterium agent. The provided ultrahigh-temperature aerobic composite biological bacterium agent comprises 50-60 parts of high-temperature-resistant composite microbial powder, 15-30 parts of a composite carrier, 5-12 parts of an adsorbent and 3-10 parts of a decomposition accelerator. The ultrahigh-temperature aerobic composite biological bacterium agent thoroughly decomposes kitchen waste, has areduction rate of the kitchen waste reaching 95% or above, also has decomposition efficiency, enables fruit and vegetable kitchen waste to be decomposed within 0.5 h, enables decomposition of meat and bone kitchen waste to be completed within 2-4 hours, effectively achieves a harmless treatment of the waste, at the same time can effectively inhibit growth of spoilage microorganisms in the kitchenwaste and eliminates foul smells generated in a waste degradation process.

Description

technical field [0001] The invention belongs to the technical field of garbage treatment, and in particular relates to a preparation method and application of an ultra-high temperature aerobic composite biological bacterial agent. Background technique [0002] With the continuous development of my country's social economy and people's lives, as well as the continuous advancement of domestic waste classification work nationwide, the demand for rapid processing technology for domestic kitchen waste continues to increase, and the problem of domestic waste disposal has become more and more prominent. However, the problem of domestic waste disposal in my country is still an unsolved problem. Domestic kitchen waste refers to garbage such as leftovers and discarded edible organic waste generated before and after meals in the daily life of residents. The main components are starch, food fiber, animal fat and other organic substances. The moisture content is high, the rate of decay a...
