UASB (Upflow Anaerobic Sludge Blanket) integrated device for improving biodegradability of battery wastewater

The utility model discloses a UASB (Upflow Anaerobic Sludge Blanket) integrated device for improving the biodegradability of battery wastewater, which comprises a tank body, the top surface of the tank body is fixedly connected with a siphon pulse tank, the inner wall of the siphon pulse tank is fixedly connected with a water inlet pipe, and the inner wall of the siphon pulse tank is fixedly connected with a first exhaust pipe; when the water level rises to the highest point of the siphon, the wastewater in the siphon pulse tank quickly enters the water distribution well through the siphon under the action of the atmospheric pressure difference inside and outside the siphon cover, and then is discharged by the water distribution pipe in a pulse water distribution manner to be mixed with sludge; the adsorption mechanism degrades pollutants in wastewater and intercepts sludge at the same time, methane gas generated in the anaerobic process is discharged through the gas collecting pipe on the inner wall of the t
