Problems solved by technology

One is landfill, although it can absorb a large amount of waste, it is easy to cause secondary pollution of groundwater resources for a long time, and also produces harmful gases such as methane, which will consume a lot of land; the other is incineration, which is an incineration plant for pure waste The construction and production costs are quite expensive, which will bring a huge economic burden to the local government. At the same time, the pure waste contains a large amount of inorganic and water-containing substances. When the incineration temperature does not meet the requirements, it will produce harmful substances such as dioxin, which is very toxic. Cause secondary pollutants to the environment; the third is composting,

Embodiment 1

[0029] Sorting urban and rural wastes into recyclable wastes, combustible wastes, organic wastes, and other wastes on the sorting carousel, among which wastes that are both combustible and organic matter are classified as combustible wastes. Other waste refers to the waste left after removing recyclable waste, combustible waste and organic waste from urban and rural waste. The high-efficiency smokeless atmospheric pressure hot air and hot water dual-purpose garbage incinerators are connected with fermentation tanks, fly maggots and earthworm breeding rooms, and composting fermentation equipment to form a heating system. The combustible waste is incinerated by the garbage incinerator, and the heat generated can be supplied to the fermentation tank, fly maggot and earthworm breeding room, and composting fermentation equipment. Incineration products of combustible wastes and other wastes are thrown into the residue pool for landfill. After the organic waste is crushed to obtain ...

Abstract

The invention relates to urban and rural waste treatment and utilization, in particular to an urban and rural waste treatment method. The method comprises the following steps: sorting and classifying wastes; smashing organic wastes and then adding a microbial starter, and adding straw or sawdust to regulate water content; after stirring, carrying out anaerobic fermentation in a fermentation tank, and using the anaerobic-fermented product as feed for fly larvae and earthworm breeding; collecting residues of fly larvae and earthworm breeding, and composting and fermenting to prepare organic fertilizers. Combustible wastes are incinerated through an incinerator to supply heat for the fermentation tank, fly larvae and earthworm breeding rooms and composting fermentation equipment. The method carries out resource utilization, innocent treatment and reduction landfill for the wastes and fundamentally controls the secondary pollution caused by the direct landfill, incineration and composting of wastes.

Description

technical field [0001] The present invention relates to waste, in particular to waste treatment and utilization. Background technique [0002] Urban and rural waste refers to the collection of domestic garbage, human and animal manure, market garbage, various types of food, leftovers from non-staple food processing plants, etc. Today, there are landfill, incineration, and composting methods for its treatment. These methods have their own disadvantages . One is landfill, although it can absorb a large amount of waste, it is easy to cause secondary pollution of groundwater resources for a long time, and also produces harmful gases such as methane, which will consume a lot of land; the other is incineration, which is an incineration plant for pure waste The construction and production costs are quite expensive, which will bring a huge economic burden to the local government. At the same time, the pure waste contains a large amount of inorganic and water-containing substances. ...
