A high-efficiency resource-based aerobic fermentation device for urban domestic waste

Abstract

The invention discloses a high-efficiency resource-based aerobic fermentation device for urban domestic waste, which comprises: an aerobic fermentation box, a composite centrifugal crushing and pulping machine installed on the top of the aerobic fermentation box; A fermentation liquid collection tank is provided; the mixer is driven to rotate by the first motor; one end of the fermentation liquid collection tank is connected with a fermentation liquid collection pipe; the other end of the fermentation liquid collection pipe is connected to the aerobic fermentation box through the water pump and the chemical dosing port in sequence . The high-efficiency resource-based aerobic fermentation device for urban domestic waste provided by the present invention uses a compound centrifugal crushing pulper to slurry organic matter into a fluid state and falls into an aerobic fermentation tank for fermentation, and the obtained fermentation liquid is returned to the aerobic fermentation tank through a water pump In the reflux process, high-temperature aerobic fermentation bacteria and heavy metal passivation regulators are added through the chemical dosing port to improve the efficiency of aerobic fermentation, improve the purity of fermentation products, and make full use of organic matter in urban domestic waste.

Description

technical field [0001] The invention relates to the technical field of solid waste treatment, in particular to an aerobic fermentation device for high-efficiency resource utilization of urban domestic waste. Background technique [0002] With the improvement of my country's urban economic level and the improvement of people's living quality, the output of domestic waste in urban areas has also increased rapidly. At the same time, a large amount of agricultural waste, poultry manure, dust, etc. The content is extremely high, but in the past, most cities and towns used simple landfills and temporary piles for incineration of village and township garbage, which not only polluted the soil, water, and atmospheric environment, but also caused a great waste of available resources. [0003] Even if some areas have composted organic matter in urban waste, there are still problems such as long composting cycle, low product yield, and low product purity. [0004] Therefore, how to prov...
