Problems solved by technology

It not only solves the way out of garbage, but also achieves the purpose of recycling. However, the amount of domestic garbage compost is large and the nutrient content is low. Long-term use will easily cause soil compaction and groundwater quality deterioration. Therefore, the scale of composting should not be too large

Embodiment Construction

[0029] As shown in the figure, a comprehensive domestic waste treatment method includes the following process steps:

[0030] 1) Rough selection: separate broken clothes, large pieces of construction waste, and foreign objects that are not easy to break, such as wood and summer mats;

[0031] 2) Feeding:

[0032] 2-1. Use a forklift to send domestic garbage to the plate feeding device through the receiving funnel;

[0033] 2-2. The plate feeding device sends the domestic garbage to the feeding belt conveyor through the uniform feeding device;

[0034] 3) Magnetic separation: the household garbage is sent to the strong magnetic iron remover through the feeding belt conveyor, and the ferromagnetic substances are selected;

[0035] 4) Crushing and screening: The household garbage after magnetic separation is sent to the garbage crusher, which crushes the household garbage with larger particle size, and the crushed household garbage enters the first-level drum screening machine ...

Abstract

The comprehensive treatment method of domestic waste involves rapid and harmless treatment of domestic waste through roughing, feeding, magnetic separation, crushing and screening, winnowing, secondary magnetic separation and anaerobic carbonization. The device of the present invention uses a first-stage drum screening machine, a second-stage drum screening machine, a strong magnetic iron remover and an anaerobic carbonization furnace to mechanize domestic garbage, first crushing and screening, and then magnetic separation, which greatly improves the efficiency of the strong magnetic iron remover. The use efficiency is high, through the anaerobic carbonization furnace, the harmless treatment of living garbage is realized. At the same time, the method of the present invention can make domestic garbage into coal, heat energy and building materials, and realize the effect of turning waste into treasure. .

Description

technical field [0001] The invention relates to a domestic garbage treatment method, in particular to a rapid, harmless and resource recycling comprehensive domestic garbage treatment method. Background technique [0002] According to statistics, about 2 / 3 of the cities in our country are trapped in the predicament of garbage siege. The annual output of municipal solid waste in my country alone is nearly 150 million tons, most of which are stacked in the open air. It not only affects the urban landscape, but also pollutes the atmosphere, water and soil that are vital to our lives, and poses a great threat to the health of urban residents. Garbage has become a very difficult problem in the process of urban development and social progress. Moreover, with the continuous improvement of people's living standards, the amount of domestic garbage produced is increasing, the growth rate is getting faster and faster (increasing at a rate of 6% per year), and the composition is becomi...
