Embodiment Construction

[0030] Describe the present invention in detail below in conjunction with accompanying drawing, figure 1 It clearly shows the process flow of the present invention: a combined treatment method of leachate and kitchen waste in a garbage transfer station, the process steps of which are as follows:

[0031] S1. Food waste pretreatment

[0032]After the kitchen waste is separated from the solid and liquid, the liquid part enters the oil-water separator, and the separated oil can be used as a resource, such as biodiesel; the solid part is manually separated from impurities (such as chopsticks, plastic bags, etc.) The food filtrate treated by the separator is crushed together to produce food slurry, and enters the hydrolysis acidification adjustment tank;

[0033] S2. Pretreatment of leachate in the garbage transfer station

[0034] The leachate of the transfer station passes through the grid machine to remove suspended impurities in the leachate, then passes through the oil separ...

Abstract

The invention discloses a combined treatment method and device for garbage transfer station leachate and kitchen garbage. The device comprises a kitchen waste pretreatment system, a waste transfer station leachate pretreatment system, a kitchen slurry and leachate mixing treatment system and a PLC automatic control system. According to the invention, by combining the actual condition of the garbage transfer station and aiming at the attribute characteristic of good biochemical effect of the garbage transfer station leachate and the kitchen waste, an efficient and rapid comprehensive treatment mode is carried out from the source, so that the problems that the garbage transfer station leachate and the kitchen waste are separately and independently collected and are difficult to collect, the cost is high and the environment is polluted are effectively solved, and reduction and resourceful treatment are really realized from the source.

Description

technical field [0001] The invention belongs to the technical field of waste and wastewater treatment, and relates to a combined treatment method and device for leachate and kitchen waste in a garbage transfer station. Background technique [0002] With the continuous improvement of people's living standards, the requirements for environmental conditions are also increasing. The traditional garbage stations in urban and rural areas can no longer meet people's requirements for new concepts such as high efficiency, environmental protection, energy saving and low consumption. Therefore, the promotion of compressed garbage transfer stations has great potential. It must be done. The compressed garbage transfer station is leading the development of the garbage transfer station industry due to its small footprint, good concealment, and reasonable space structure. [0003] The garbage transfer station is an important part of urban garbage collection and disposal. The promotion and ...
