Problems solved by technology

[0004] The landfill method covers a large area and requires anti-seepage treatment. It is also necessary to build a biogas recovery system and a leachate treatment plant, which is likely to pollute the groundwater and surrounding air, and the resources cannot be recycled; for a large population and increasingly scarce arable land resources For our country, it is becoming more and more difficult to implement
[0005] The incineration method requires a large investment and high operating costs, and cannot fully realize the recycling of resources. More...

Embodiment Construction

[0014] As shown in the accompanying drawings, in one embodiment of the present invention, the flow process of the method of the present invention is: use the driving grab to load the municipal solid waste into the cooking tank, then close the feed port, and feed water steam for cooking. After the perishable garbage is boiled into slurry, open the feed port, turn over the tank body, dump all the garbage into the dehydration tank, and then use the driving grab to grab the solid garbage and send it to the draining / fermentation tank to continue dehydration. After dehydration The garbage is then grabbed by the driving grab bucket and sent to the sorting system. The sorted light garbage is used for recycling, the nutritious soil is used for landscaping, and the heavy garbage is sent to landfill after the metal is separated by magnetic separation. After the treatment, the biogas produced in the sewage treatment process is used to burn and produce steam for personal use, thus realizing...

Abstract

The invention relates to an urban domestic garbage treatment method with the steps of cooking firstly and sorting secondly, which mainly comprises the following steps of: loading urban domestic garbage into a cooking kettle by using a grab bucket of a travelling crane, introducing water vapour, cooking, turning over a kettle body when the garbage easy to rot in the urban domestic garbage is cooked into slurry, pouring all the garbage into a dewatering pool, then grabbing the dewatered garbage by using the grab bucket of the travelling crane and delivering to a sorting system, wherein the sorted light garbage is used for recycling, nutritional soil is used for landscaping, heavy garbage is delivered for landfill after metal is dressed by magnetic separation, the removed sewage reaches the standard after treatment and is discharged, and methane generated in the sewage treatment process is used for combustion to produce vapour for private use. In this way, the hazard-free, reduction and reclamation treatment of the urban domestic garbage is realized.

Description

Technical field [0001] The invention belongs to the technical field of urban solid waste treatment and is suitable for the construction of urban domestic garbage treatment plants of different scales. Background technique [0002] As we all know, municipal solid waste is produced along with the progress of human civilization, and with the improvement of people's living standards, its quantity is also increasing rapidly, and has become a major public hazard. [0003] At present, domestic and foreign methods of dealing with municipal solid waste mainly include landfill, incineration and composting. [0004] The landfill method covers a large area and requires anti-seepage treatment. It is also necessary to build a biogas recovery system and a leachate treatment plant, which is likely to pollute the groundwater and surrounding air, and the resources cannot be recycled; for a large population and increasingly scarce arable land resources For our country, it is becoming more and ...
