High-efficiency granular sludge anaerobic tower reactor

Abstract

The invention discloses a high-efficiency granular sludge anaerobic tower reactor, which includes a tower body. The tower body includes a water distribution area arranged on the lower part, a reactionarea arranged on the middle part and a three-phase separation area arranged on the upper part, the water distribution area is provided with a raw water inlet, the raw water inlet is provided with a water distribution pipe network extending into the water distribution area, the water distribution pipe network is provided with a plurality of water distribution spraying heads toward the bottom of the tower body, a reflux water suction pipe is arranged on the lower part of the three-phase separation area, the reflux water suction pipe is provided with a plurality of reflux suction nozzles towardthe top of the tower body, the reflux water suction pipe communicates with the raw water inlet through a reflux pump, the three-phase separation area is provided with sludge settling inclined plates,and baffle plates are arranged between the sludge settling inclined plates and the reflux water suction pipe. According to the high-efficiency granular sludge anaerobic tower reactor, by ensuring sufficient mixing of muddy water at the bottom of the reactor, return sludge flow is subjected to a secondary reaction in the three-phase separation area, then sludge and water are separated thoroughly bymatching of the multilayer sludge settling inclined plates and the baffle plates, and three-phase high-efficiency separation of the sludge, the water and gas is ensured.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a high-efficiency granular sludge anaerobic tower reaction device. Background technique [0002] The traditional upflow anaerobic sludge bed and expanded granular sludge reactor are the most widely used anaerobic biological devices in the field of sewage treatment. [0003] Usually the composition of this type of reactor is divided into two parts: one part is the shell, usually cylindrical; the other part is the solid-liquid-gas three-phase separator. The reaction mechanism is mainly: the sewage to be treated is pumped in from the water inlet, the water flows through the sludge layer, the fine sludge rises under the impact of the water flow, the mud-water mixture passes through the reaction zone and the three-phase separator in turn, and the waste water finally reaches the outlet. The water exits the reactor. Activated sludge, gas, and water are separated in the three-...

AI Technical Summary

Problems solved by technology

[0004] At present, the reactor still has the problem of unsatisfactory mud-water mixing in the reaction zone and unsatisfactory separation of mud-water in the three-phase separation zone, which reduces the mass transfer efficiency of the entire anaerobic reactor. How to overcome the above problems and improve the process of the anaerobic tower. application is important
