Problems solved by technology

On the one hand, it will harm the water ecosystem and seriously pollute the surrounding environment because it affects the reoxygenation of the water body and its natural purification process; on the other hand, it is also easy to cause blockage of sewage channels and cause other negative effects
[0009] Secondly, from the perspective of sanitation and epidemic prevention, food waste oil is refined into "gutter oil" in the open air in some underground workshops, and harmful components such as bacteria in food waste oil cannot be released, and will seriously endanger people's physical and mental health after entering the market healthy

Embodiment 1

[0024] Four forms of food waste oil distribution in water: first, oil slick: this kind of oil has larger particles dispersed in water, and the diameter of oil particles is generally greater than 100um. water surface. Second, disperse the oil; the diameter of the oil dispersed in the water is 10-100um, suspended in the water as tiny oil droplets, which is unstable and often forms an oil slick after standing still for a certain period of time. Third, emulsified oil: the diameter of the oil plant is less than 10um, generally 0.1-2.0um, often due to the presence of active agents in the water, the oil plant forms a stable emulsion. The stability of emulsified oil depends on the nature of wastewater and the degree of dispersion of oil droplets in water, the greater the degree of dispersion, the more stable it is. Fourth, dissolved oil: Oil is dispersed in the water body in a molecular state or chemical way, forming a stable homogeneous system with a diameter generally less than a f...

Abstract

The invention aims at providing a composite flora for processing food waste grease. The composite flora contains pseudomonas fluorescens and bacillus alcalophilus, wherein the pseudomonas fluorescens is preferably the pseudomonas fluorescens with the collection number being 1.3990 collected in the CGMCC (China General Microbiological Culture Collection Center); the collection number of the bacillus alcalophilus is CGMCC No.9430. Through the composite flora, the addition of the microbial inoculums XS2-450 has the positive influence on the food waste grease degradation; in addition, the degradation capability of pseudomonas fluorescens 1.3990 on the grease can be greatly improved, and is improved from 60 percent to 92 percent.

Description

technical field [0001] The invention belongs to the technical field of food waste oil degradation, and in particular relates to a composite bacterial group for treating food waste oil. Background technique [0002] Food waste refers to the waste generated during the production, processing, transportation and use of food. Food waste refers to non-edible animal and vegetable oils and various oil-water mixtures produced by residents in their daily production and in food processing, catering services, unit meals and other activities in factories and schools. With the development of my country's economy and the increase of population, the output of kitchen waste has increased significantly in recent years. At the same time, the proportion of food waste content in the total urban waste content is also constantly increasing, often reaching about 70% in some large cities, and the food fat content also increases accordingly. [0003] According to statistics, the daily output of kit...
