Push-flow circulating microbubble and surface aeration membrane biological reactor

Abstract

Provided are a push-flow circulating microbubble and a surface aeration membrane biological reactor. The surface aeration membrane biological reactor mainly comprises a pool body. The inner space of the pool body is divided into a membrane pool and a biochemical pool through a partition wall, a membrane module is installed in the membrane pool and horizontally arranged along the water flow direction, membranes on the membrane module are installed along the horizontal direction, and a membrane module water collecting pipe is located below the water surface. The membrane module is composed of the membranes, the membrane module water collecting pipe and a membrane module supporting pipe, and all the membranes are communicated with the membrane module water collecting pipe, connected with a water collecting branch pipe through a water outlet nozzle of the assembly module water collecting pipe, and converged to a water collecting main pipe. A flow-pushing device is mounted at one end of the membrane module or at the turning position of the inner portion of the pool body, the water flow direction of the flow-pushing device is horizontal, a micropore aeration tube is arranged at the end of the membrane module far away from the flow-pushing device, aeration is performed at the end of the membrane module far away from the flow-pushing device, and a raw water pipe and a sludge discharging pipe are arranged on one side of the pool body located at the biochemical pool.
