Abstract

The invention discloses a biological treatment device for landfill leachate treatment. The device comprises a reactor, wherein the reactor is provided with an air supply fan; an air supply tube is fixedly connected with the air supply fan; the air supply tube extends into the reactor; a holding plate is fixedly connected in the reactor; a water pump is fixedly connected with the holding plate; a water inlet tube of the water pump penetrates through the holding plate downwards; a mounting plate is fixedly connected with the holding plate; a linking shaft is rotationally connected with the mounting plate; a diffusion arc plate is fixedly connected with the linking shaft; a first poke plate is fixedly connected with the circumferential wall of the linking shaft; a motor is fixedly connected with the holding plate; a second poke plate is fixedly connected with a rotating shaft of the motor; and a resetting mechanism for resetting the linking shaft is arranged on the circumferential wall ofthe linking shaft. The solubility of oxygen in a leachate can be increased, and oxygen supply to aerobic microorganisms can be ensured. The invention provides a biological treatment method for landfill leachate treatment. The biological treatment method comprises the following steps: S1, performing aeration on the leachate; S2, performing anaerobic placing on the leachate; and S3, filtering a treatment liquid by using a semipermeable membrane.

Description

technical field [0001] The invention relates to garbage treatment, in particular to a biological treatment device and method for treating garbage leachate. Background technique [0002] Landfill leachate is a black or yellowish-brown liquid with a foul smell. The leachate contains a large amount of organic and inorganic substances, including various refractory organic substances, inorganic salts and metal ions. [0003] The traditional landfill leachate treatment methods include: biological treatment and physicochemical treatment. The biological treatment mainly relies on biological anaerobic and aerobic reactions to treat landfill leachate. [0004] In traditional aerobic reactors, aeration is usually used to provide oxygen to aerobic microorganisms in landfill leachate, but the solubility of oxygen in water is small, and most of the oxygen is discharged from the aerobic reactor without being dissolved in water , low aerobic efficiency. Contents of the invention [0005...
