New composting apparatus for treating a plurality of solid wastes

Abstract

The invention relates to a new composting apparatus for treating a plurality of solid wastes. The new composting apparatus comprises a plurality of storage bins and a plurality of pretreatment bins, wherein the pretreatment bins are correspondingly connected to the storage bin one by one, the pretreatment bins are connected to a mixing stirrer, and the mixing stirrer is sequentially connected to aprimary fermentation bin, an aging bin, a screening machine and a finished product bin. Compared with the existing compost devices, the new composting apparatus of the present invention has the following characteristics that the process is easy to control, the garbage waste is subjected to centralized treatment, the water content during the composting is effectively controlled, the feeding is uniform, the large-scale composting can be achieved, the relative investment is low, the product quality can easily meet the requirements of the national standard NYNY 525-2002 organic fertilizer, the problems that the nutrients of the finished product does not meet the standard and the harmful substances of the finished product exceed the standard are solved, and a variety of solid wastes in a township can be treated by a set of the apparatus so as to substantially improve the efficiency.

Description

technical field [0001] The invention relates to the field of composting equipment, in particular to a new composting device for processing various solid wastes. Background technique [0002] The solid waste that can be treated by composting in cities mainly includes domestic garbage, kitchen waste, livestock and poultry manure and municipal sludge. Due to different solid waste management departments, at present, most of the composting of solid waste uses different raw materials and different devices, and there are certain defects in the single raw material composting device, such as: composting with domestic waste, low organic matter and nitrogen, phosphorus and potassium nutrients, production The organic fertilizer does not meet the national organic fertilizer standard; the food waste composting raw material has high moisture content and high oil content, and the process is difficult to control, and the organic fertilizer produced has the problem of unqualified bacteria and...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to solve the above problems, provide a new composting device for processing various solid wastes, and solve the problems of low nutrient, excessive heavy metals, dispersion of garbage and waste, difficult control of moisture in the composting process, and uneven support in the prior art. The reaction temperature is low, there are many types, the scale of composting is small, and the relative investment is high
