Problems solved by technology

Due to the erosion of sewage and the aging of biological bacteria, they fall and deposit on the bottom of the pool, and cannot effectively play the role of falling activated sludge.
At present, there is a method of installing a push-flow pump at the bottom of the pool to stir the sewage at the bottom of the pool to drive the activated sludge to float up. This has a certain effect on the treatment of small-volume square pools, but it has a certain effect on the treatment of large-volume pools, especially rectangular pools. not big

Abstract

An anaerobic biochemical pool for sewage treatment comprises a biochemical pool body, a water inlet pipe and a water outlet pipe, and an inverted wall and an overflow wall are arranged in the biochemical pool body close to the water inlet pipe and the water outlet pipe respectively; a plurality of rows of suspension type combined fiber bundle discs are arranged between the inverted wall and the overflow wall; a horizontally arranged reflux pipe network is arranged at the bottom in the biochemical pool body, and water aeration discs are uniformly distributed and connected below each main pipeline of the reflux pipe network; each water aeration disc comprises a central pipe, a conical mud breaking disc and a plurality of conical flow guide discs are sequentially arranged on the central pipe from top to bottom, the diameters of the plurality of flow guide discs are sequentially increased from top to bottom, and zigzag notches are uniformly distributed in the edge of a disc opening of each flow guide disc; and sawtooth-shaped convex teeth are arranged on the outer side disc surface of each mud breaking disc and are used for breaking larger activated sludge particles raised by reflux liquid into smaller particles. According to the biochemical pool, activated sludge deposited at the bottom of the anaerobic biochemical pool can be in a fluidized state without a plug-flow pump, the optimal treatment effect of anaerobic biochemistry is ensured, and wide popularization and application prospects are realized.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an anaerobic biochemical pool for sewage treatment. Background technique [0002] At present, many units in China apply biochemical processes to treat industrial wastewater containing phenol, cyanide, oil refining, chemical industry, and petrochemical industry. In the anaerobic biochemical system, install and fix filamentous fillers as the carrier of biological anaerobic bacteria. The spacing between the fillers is about 200mm, the upper end is about 200mm below the water surface, and the lower end is more than 1000mm from the bottom of the pool. The organic matter in the sewage is broken chain, open ring and degraded by the attached biological anaerobic bacteria on the carrier. Due to the erosion of sewage and the aging of biological bacteria, they fall and deposit on the bottom of the pool, so they cannot effectively play the role of falling activated sludge. At pres...
