System and method for processing rubbish percolate

Abstract

The invention discloses a system and a method for processing rubbish percolate. The system comprises a collecting pool, a middle pool, a vibrating film nano-filtration device and an evaporation device, wherein the vibrating film nano-filtration device comprises a shell, a diaphragm set and a motor; the diaphragm set downward extends, thereby forming a central driving rod; the motor and a belt areused together for driving an eccentric block on the central driving rod to rotate so as to generate a centrifugal force which can trigger vibration; the diaphragm set is driven to vibrate by energy generated from vibration, with the help of the central driving rod; and a shearing force which is generated by high-frequency vibration is spread in a sine form by the surface of a diaphragm in the diaphragm set, thereby efficiently solving a chocking problem of the diaphragm in the diaphragm set, achieving higher capability of resisting diaphragm pollution, realizing simple and efficient treatmentfor the rubbish percolate and achieving a better treating effect. A recycling system which is composed of the collecting pool, the middle pool and the evaporation device is used for continuously and efficiently separating clean liquid from concentrated liquid. The clean liquid meets the standard and is discharged. The concentrated liquid is evaporated and treated by the evaporation device, thereby achieving the purposes of reducing emission and reducing wastes.

Description

technical field [0001] The invention relates to the technology in the field of waste water treatment equipment, in particular to a landfill leachate treatment system and method. Background technique [0002] Landfill leachate is a liquid formed by endogenous water and external water (including atmospheric precipitation, surface water, groundwater intrusion, etc.) produced after garbage decomposition. The water quality of landfill leachate is quite complicated, generally containing high concentrations of organic matter, heavy metal salts, SS and ammonia nitrogen, landfill leachate not only pollute soil and surface water sources, but also pollute groundwater. [0003] At present, the treatment of landfill leachate mainly adopts biodegradation method. The main reason is that the operation cost is low. However, due to the high proportion of polymer compounds that are difficult to degrade in the leachate and the inhibitory effect of heavy metals, after the commonly used biologica...
