Description

Comprehensive resource treatment system for fruit and vegetable garbage and bamboo forest waste

Technical Field

The utility model belongs to the field of garbage treatment, and relates to a comprehensive recycling treatment system for fruit and vegetable garbage and bamboo forest waste.

Background

With the rapid development of economy and the improvement of the living standard of people, kitchen waste generated in daily life of people becomes one of the major problems troubling the society. The fruit and vegetable garbage belongs to one of the types of garbage which accounts for a large proportion in the kitchen garbage, is not easy to naturally degrade, and has a low calorific value, so that the fruit and vegetable garbage is not suitable for garbage disposal methods such as a traditional landfill method or an incineration power generation method.

Because the kitchen waste contains high organic matter content and is easily degraded and decomposed by aerobic microorganisms into organic fertilizer capable of improving soil, the utilization of microorganisms to carry out resource treatment on the kitchen waste is one of the current research hotspots. However, due to the problem of people's dietary habits, kitchen waste generally contains high-concentration salt and oil, and microorganisms have poor capability of treating salt and oil, so that the salt and oil thereof need to be separated through a series of treatment processes, which is very costly. And the fruit and vegetable garbage does not contain grease and salt, so that the fruit and vegetable garbage and other kitchen garbage are separately treated, and the great economic cost and time cost can be saved.

Because the organic matter content of the fruit and vegetable garbage is too high and exceeds more than 90 percent, the fermentation process is slow because of too large oxygen consumption in the research of aerobic microbial fermentation of the fruit and vegetable garbage alone. In order to solve the problem, the utility model uses bamboo forest waste with low organic content as auxiliary material to dilute the organic matter so as to promote the aerobic fermentation process. Finally, the organic fertilizer obtained after the comprehensive resource fermentation of the fruit and vegetable garbage and the bamboo forest waste can be reused for fruit and vegetable farms and bamboo forest planting, so that a green circulating resource channel is formed.

In the prior art, the comprehensive resource treatment technology of the fruit and vegetable garbage and the bamboo forest waste is not perfect, and at least the following problems exist in the treatment process:

(1) garbage treatment is generalized, and screening and classification are not carried out, so that the subsequent garbage treatment cost is high, and the resource conversion efficiency is low;

(2) the problem of serious secondary pollution or resource waste is easily caused in the treatment process;

(3) the problem of disinfection is not considered in the garbage disposal process;

(4) the utilization of the resource products formed by the treatment of the fruit and vegetable garbage and the bamboo forest waste is difficult, and the closed loop of the garbage resource treatment is difficult to form. And high secondary cost, such as transportation cost, labor cost and the like, is easily caused in the resource product utilization process.
