Embodiment 1

[0034] see figure 1 , Embodiment 1 of the present invention provides a garbage treatment process S10, comprising the following steps:

[0035] Pretreatment step S11, sorting the garbage, sorting out the garbage containing 15%-20% non-dissolved organic matter, and collecting the filtrate leached from the garbage during the sorting process;

[0036] Filtrate processing step S12, the filtrate is left to stand for stratification, the oil in the upper layer of the filtrate is adsorbed by an lipophilic component, and a suction device is arranged above the lipophilic component to extract the grease in the lipophilic component , collecting the water in the lower layer of the filtrate for use in garbage fermentation and humidification;

[0037] Fermentation step S13, naturally fermenting the garbage containing 15%-20% non-dissolved organic matter to obtain the fermentation intermediate product, adding a spray containing probiotic strains to the fermentation intermediate product to car...

Embodiment 2

[0079] see Figure 4 , Embodiment 2 of the present invention provides a garbage filtrate treatment system 10, including a filtrate collection tank 11 for collecting garbage filtrate, an oil-water separation tank 11 arranged on one side of the filtrate collection tank 11 and communicated with the filtrate collection tank 11 Pool 12, the oil removal device 13 that is arranged on the top of the oil-water separation pool 12 for removing grease in the garbage filtrate, and the buffer pool 14 that is arranged on one side of the oil-water separation pool 12 and communicates with the oil-water separation pool. The degreasing device 13 includes an oleophilic component 131 arranged on the top of the oil-water separation pool 12 for absorbing grease and a lipophilic component 131 arranged on the top of the oleophilic component 131 for extracting the grease in the oleophilic component. Suction device 132 .

[0080] In this design mode, by setting the lipophilic component 131 for absorbin...

Abstract

The invention discloses a waste treatment process. The waste treatment process comprises the following steps: a step of pretreatment: sorting wastes so as to sort out waste containing 15% to 20% of aninsoluble organic matter, and collecting a filtrate leached from the wastes in the process of sorting; a step of filtrate treatment: subjecting the filtrate to standing and layering, allowing an oleophilic component to adsorb oil located at the upper layer of the filtrate, dissociating the oil from the oleophilic component through a suction device arranged at the upper part of the oleophilic component, and collecting a water liquid located at the lower layer of the filtrate for fermentation and humidification of the wastes; and a step of fermentation: subjecting the waste containing 15% to 20% of the insoluble organic matter to natural fermentation so as to obtain a fermentation intermediate product, and adding a spray agent containing probiotic bacteria into the fermentation intermediateproduct for biological bacterial fermentation so as to obtain an organic fertilizer. The waste treatment process provided by the invention has the following advantages: the waste treatment process does not cause pollution to the environment, realizes cyclic utilization of resources, facilitates thorough fermentation of the wastes, and can generate a high-quality organic fertilizer.

Description

[0001] The invention relates to the field of garbage treatment, in particular to a garbage treatment process. Background technique [0002] At present, the domestic municipal solid waste solutions are mainly incineration and landfill. Among them, waste incineration has three major disadvantages. First, a large amount of leachate needs to be discharged and treated; second, 30% of the slag needs to be treated by downstream technologies; third, it will produce dioxin and fly ash pollution. While landfill occupies a large amount of land resources, there is also soil pollution and air pollution caused by leachate. [0003] That is to say, the existing waste treatment methods of incineration and landfill, on the one hand, pollute the environment, and on the other hand, cannot realize the recycling of resources. Contents of the invention [0004] In order to overcome the deficiencies of the prior art, the invention discloses a garbage treatment process, which is used to solve the ...
