Household garbage resource recycling process

Abstract

The invention relates to a household garbage resource recycling process. According to the household garbage resource recycling process, household garbage is separated and classified step by step through hydraulic flotation until being recycled after being washed and sorted; meanwhile, washing wastewater is subjected to an anaerobic acidification process, and generated methane is recovered in a centralized mode for power generation; odor generated in the production process is cleaned by a low-temperature plasma oxidation deodorization technology; and at last, surplus wastewater is subjected to electrochemical decoloration to achieve emission on standard. According to the circulation, the purpose of purifying and recycling the household garbage can be achieved. According to the household garbage resource recycling process, the household garbage generated in every day of a city is all subjected to reduction, harmlessness and resource treatment, dioxin and secondary pollution are avoided, and accordingly the purpose of cleaner production is achieved.

Description

technical field [0001] The invention relates to recycling of garbage, belongs to the field of environmental engineering, and in particular relates to a process for resource recycling of domestic garbage. Background technique [0002] With the rapid development of my country's economic construction and urban construction, the urban framework is getting bigger and bigger, the urban population is increasing rapidly, and the amount of domestic garbage is also increasing. The original simple garbage dumps were piled up naked, mosquitoes and flies were born, plastic bags were flying all over the sky, and it spread to the suburbs and suburban villages. Around the garbage dump, there are serious problems such as sewage overflow, land occupation, and groundwater pollution, which have seriously affected the normal life of the surrounding residents and the natural ecological environment. [0003] At present, domestic waste treatment in my country mainly adopts filling method and incin...

AI Technical Summary

Problems solved by technology

[0003] At present, domestic waste treatment in my country mainly adopts filling method and incineration method, among which landfill method is the most used negative waste treatment method. Its disadvantages are that the project occupies a large area, the degradation rate is slow, and there is a risk of secondary pollution. Potential threats, and all recyclable resources in garbage are wasted; although the incineration method has a good reduction effect and relatively thorough treatment, there are objective problems of resource destruction, serious air pollution, and easy production of toxic substances such as dioxins

In summary, with the advancement of science and technology and the gradual strengthening of people's awareness of environmental protection, the existing waste disposal methods can no longer adapt to the sustainable development of ecology. Therefore, the current industry urgently needs a resource-based, pollution-free, clean and environmentally friendly Garbage treatment process
