Improved structure of deflection type internal circulation biomembrane reactor

Abstract

The invention relates to an improved structure of a deflection type internal circulation biomembrane reactor, which comprises a reactor body (1). The improved structure is characterized in that the reactor body (1) is divided by a division board (2) into a water turbulent flow region (101) and a biological reaction region (102) in the horizontal direction; the biological reaction region (102) is divided by at least two small division boards (3) into water channels (4); water in the water channels (4) circularly flows in the reactor from left to right in a vertical deflection mode; honeycomb ceramic (5) is mounted between the small division boards (3); and aerating holes (6) are formed at the bottom between the two small division boards (3) where the water is in an upward flow state. According to the invention, the built-in honeycomb ceramic supporter is used as the biomembrane supporter, so that the surface area of the biomembrane is increased, and the biological wastewater treatment efficiency is enhanced. Meanwhile, the aerators are mounted at the bottom of the upward flow channels among the deflection channels, so that the aeration amount can be regulated to control the dissolved oxygen content in the reactor according to the load condition during wastewater treatment, thereby achieving the purpose of efficiently removing organic substances, ammonia nitrogen and total nitrogen in wastewater.

Description

technical field [0001] The invention belongs to the technical field of waste water treatment equipment, and specifically relates to a baffled internal circulation biofilm reactor with a built-in honeycomb ceramic as a biofilm carrier, so as to improve the treatment capacity of waste water. Background technique [0002] With the development of the economy, the urban population has expanded rapidly, and the discharge of urban domestic sewage has increased sharply. Traditionally, urban domestic sewage is often directly discharged into surface waters such as rivers and lakes after being treated by urban sewage treatment plants. However, the treated sewage Urban domestic sewage is still rich in a large amount of nitrogen and phosphorus substances. Direct discharge into rivers and lakes will cause eutrophication of rivers and lakes, leading to pollution of surface water and major damage to the ecological environment. Therefore, at present, all cities are upgrading the sewage treat...

Problems solved by technology

However, this structure using ceramic plates as biofilm carriers has less biomass due to its small surface area, which reduces the efficiency of biological treatment and reduces the ability of biofilm reactors to treat wastewater.
