Embodiment Construction

[0047] The following are specific embodiments of the invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0048] Such as figure 1 as shown,

[0049] This garbage transfer station leachate recycling device includes a grid machine 1 and a regulating tank 2 arranged in sequence, and the device also includes a UASB reactor 3, an aerobic tank 4, and a well Oxygen unit 5, sedimentation tank 6 and biological activated carbon system 7;

[0050] The effluent of the UASB reactor flows into the aerobic tank 4, and the biogas produced by the UASB reactor is discharged and collected from above the UASB;

[0051]The HRT of the UASB reactor is 2d, the organic load is 10-15kgCOD / m3·d, and the temperature is controlled at 30-35°C.

[0052] The processing and recycling method of the device comprises the following steps:

[0053] S1. The leachate pr...

Abstract

The invention belongs to the technical field of environmental protection and particularly relates to a recycling device of leachates of a garbage transfer station. The device solves the technical problems of low disposal efficiency and the like in the prior art. The recycling device of the leachates of the garbage transfer station comprises a grid machine, an adjusting tank, a UASB reactor, a facultative oxygen tank, an aerobic unit, a sedimentation tank and a biological active carbon system which are sequentially arranged. The device has the advantages of being low in cost, environmentally friendly and capable of further utilizing resources.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a leachate resource treatment and reuse device of a garbage transfer station. Background technique [0002] With the advancement of my country's urbanization and the continuous improvement of people's living standards, the daily amount of garbage in my country's cities is also increasing. A large number of garbage transfer stations have also begun to be constructed and used. At the same time, a large amount of landfill leachate is also produced during the transfer of garbage at the transfer stations. Landfill leachate has complex components, high pollutant concentration, and strong odor. If it is not treated in time, it will pose a huge threat to the ecological environment and people's physical and mental health. [0003] At present, the leachate treatment technologies of transfer stations mainly include biochemical methods, physical chemical methods...
