Problems solved by technology
Firstly, the present invention manually pre-sorts household garbage, which has the disadvantage of low sorting efficiency, and household garbage that has not undergone any treatment is easily entangled, which undoubtedly further increases the difficulty of sorting. Combustible components are incinerated, which easily produces a large amount of harmful gases such as dioxins. If they are directly discharged, they will cause air pollution. If the gases are treated, the treatment cost will be greatly increased. In summary, there are deficiencies that need to be improved. place

Embodiment Construction
[0027] refer to figure 1 A further description will be given to an embodiment of a domestic garbage comprehensive treatment process of the present invention.
[0028] A comprehensive treatment process for domestic waste, the process comprises the following steps:
[0029] (1) Fresh garbage enters the site: collect domestic garbage into the site through transport vehicles or transport devices;
[0030] (2) Biological pretreatment: Place the collected garbage in the biological pretreatment workshop, spray the liquid agent with specific biological enzymes, and use the biological enzymes to carry out aerobic fermentation treatment of the organic matter in the garbage. The biodegradation enzymes are mainly protein Degradative enzymes mainly biodecompose proteins, sugars, and fruit and vegetable fibers in garbage to convert organic matter into organic fertilizers; reduce the volume of garbage, which can reduce the volume of garbage by 20%, and reduce the amount of soil landfill for...

The invention discloses a domestic garbage comprehensive treatment process, which belongs to the technical field of environmental protection. The main point of the technical scheme is a domestic garbage comprehensive treatment process. The process includes the following steps: fresh garbage entering the site, biological pretreatment, biodegradation, waste Harmless treatment, resource classification and screening, and resource collection, through the combination of biological enzymes, biomineralization degradation and mechanical methods, realize the classification and treatment of domestic waste and the application of resources. After biological treatment, the screening of waste is beneficial to shorten the Compared with direct screening without any treatment, the difficulty of screening is greatly reduced in the treatment cycle of garbage, which can effectively avoid the phenomenon of garbage entanglement. Screening through mechanical equipment reduces the labor intensity of workers and is conducive to improving In terms of work efficiency, this technical solution can achieve 100% garbage cleaning through biological treatment and screening before and after, and avoid air pollution caused by garbage incineration or soil pollution caused by garbage burial.
Description
technical field [0001] The invention relates to the technical field of environmental protection, and more specifically, it relates to a comprehensive treatment process for domestic garbage. Background technique [0002] At present, domestic and foreign domestic waste treatment technologies are all aimed at harmlessness, reduction, and recycling. The most commonly used treatment methods are landfill, incineration and composting. They have different application scopes and conditions. From recycling From an economic point of view, only by managing the whole process of garbage generation, collection, transportation and treatment can we truly achieve the harmlessness, reduction and recycling of garbage. [0003] Until now, many cities and towns in China still adopt the method of simple stacking. Since garbage is an extremely complex waste, due to biodegradation and chemical action, it will gradually rot and biodegrade over time, producing leachate and serious hazards. Explosive ...
