Integrated aerobic bio-membrane reactor

Abstract

The invention discloses an integrated aerobic bio-membrane reactor, which is characterized by comprising a reactor body, a base and a bracket, wherein the reactor body is fixed on the base through the bracket, and is divided into a precipitation area, a water outlet area, a reaction area and a water inlet area from bottom to top; a vertical frame is fixedly arranged on the base; a sludge discharge opening is formed in the bottom of the precipitation area, and is controlled to be closed and opened by a valve; a water outlet is formed in the sidewall of the water outlet area; an aerator is arranged at the bottom of the reaction area; a lightweight carrier is arranged in the reaction area; a water distributor, a water inlet pipe and a horizontal frame are arranged above the water inlet area; a hollow aeration guide pipe is arranged in the water inlet area and the reaction area in a penetration way; and an aeration pipe penetrates through the hollow aeration guide pipe and the aerator to be connected with the aerator. A unique top-in bottom-out mode is adopted, so that air can conveniently be in contact with liquid, the turbulence flow regime of the air and the liquid in the reactor is ensured, and a good mixing effect is achieved.

Description

Technical field [0001] The invention relates to an integrated aerobic biofilm reactor. Background technique [0002] With the development of industrial and agricultural production and the improvement of people's living standards, the discharge of various types of wastewater has increased sharply, which places higher requirements on wastewater treatment technology. At present, biological treatment technology with microbial technology as the core occupies an irreplaceable position in wastewater treatment. Among them, wastewater aerobic biological treatment technology is an important part of the wastewater treatment technology system and has a good development prospect. [0003] Wastewater aerobic biological treatment technology can be divided into two categories: biofilm method and activated sludge method. Although the activated sludge method is relatively mature, it also has many shortcomings and shortcomings, such as large area, high infrastructure costs, etc., and poor adaptabil...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problems existing in the existing aerobic biofilm reactor, the present invention provides an integrated aerobic biofilm reactor, which uses a light carrier attached by microorganisms, and under the action of external aeration, the carrier in the reactor It is in a suspended state, which is conducive to the replacement of biofilm, ensures its high biological activity, and avoids the clogging of the reactor; it proposes a unique water inlet and outlet method of "top in and bottom out", which is convenient for full contact of gas and liquid, and improves The utilization rate of oxygen is improved; the realized turbulent flow state strengthens mass transfer and mixing, the macroscopic reaction rate in the reactor is fast, and the ability to resist load impact is strong; the volume of each zone of the reactor is adjustable and the operation is flexible; it can realize The integration of the reaction zone and the precipitation zone in a single reactor saves the floor area of ​​the reactor
