Device for treating rubbish leachate with atmosphere plasma

Abstract

The invention provides a device for treating rubbish leachate with atmosphere plasma and relates to a rubbish treatment device. The device comprises a direct-current pulse power supply, a plasma generator, a sewage source and an air source, wherein the plasma generator is provided with an insulated cavity, a positive plate, a negative plate and an insulated pate; one side of the insulated cavity is provided with an air inlet and a water inlet, and the other side of the insulated cavity is provided with a water outlet and an air outlet; the positive plate is located on the insulated plate, thenegative plate is arranged under the insulated cavity and inserted from the negative plate fixing slot arranged below the insulated cavity, and the positive plate and the negative plate are respectively connected with the positive electrode and the negative electrode of the direct-current pulse power supply; the insulated plate is inserted from the insulated plate fixing slot in the middle of theinsulated cavity; and the air source is connected with the air inlet of the insulated cavity, and the sewage source is connected with the water inlet of the insulated cavity. By the device provided by the invention, the treatment of large-area sewage in the flowing process can be realized; and the device has the effects of high degradation speed, high degradation efficiency and the like, has simple structure, is easy to operate, and is easily popularized in the field of rubbish leachate degradation.

Description

technical field [0001] The invention relates to a garbage treatment device, in particular to an atmospheric pressure plasma treatment garbage leachate device. Background technique [0002] The pretreatment of landfill leachate treatment usually adopts anaerobic, aerobic and other biological treatment methods, and the post-treatment adopts coagulation sedimentation, filtration, adsorption and other physical and chemical methods. Among them, the cycle of the biological treatment process is long, and the degradation effect of COD and BOD in the leachate is not good. At present, Dielectric-Barrier Discharge (DBD) plasma has been successfully used in material surface modification, seed treatment, dye sewage treatment and biological material sterilization, etc., and its outstanding effect in the sewage treatment process has been recognized. However, it is a difficult point in the industry to treat large-scale and flowing sewage. [0003] Chinese patent CN102183028A discloses a l...
