Integrated reactor based on electrode-supergravity biological rotating discs and treatment method therefor

Abstract

The invention discloses an integrated reactor based on electrode-supergravity biological rotating discs and a treatment method therefor. A center shaft is arranged inside the reactor, the shaft body structure of the center shaft is a coaxial double-layer sleeve, two parts namely an air passage and a liquid passage are formed, and a through hole is formed in the outer wall of the air passage. The interior of a shell is partitioned into a plurality of communicated cavities by partition boards, each cavity is internally provided with two biological rotating discs which are fixed on the center shaft and are connected to a cathode and an anode of a power supply respectively, and the biological rotating discs serve as pairing electrodes while being taken as biofilm formation carriers. A plurality of hollow fibrous membranes are densely arranged in the middle of each disc body. According to the reactor disclosed by the invention, three technologies of electrodes, supergravity and biological rotating discs are organically combined into one reactor, so that the reactor can utilize the supergravity to carry out high efficiency mass transfer on nitrogen-containing waste gas; the nitrogen-containing waste gas is quickly dissolved in waste water; and then the biological rotating discs serve as the electrodes, so that the denitrification of microorganisms is promoted. The reactor is suitable for synchronously removing the nitrogen-containing waste gas and waste water with high concentration, and the treatment effect is greatly superior to that of an ordinary reactor.

Description

technical field [0001] The invention belongs to the field of environmental protection equipment, and in particular relates to an integrated reactor based on an electrode-hypergravity biological turntable and a processing method thereof. Background technique [0002] The existence of pollutants is a major problem left by human production activities. The treatment method should have the characteristics of mild reaction conditions, no secondary pollution, environmental friendliness and easy control. The electrochemical method has the characteristics of high efficiency and environmental protection, and has certain advantages in the harmless treatment of organic pollutants in water. [0003] Biological denitrification to remove NO from water 3- Is a very effective method, it can be NO by the role of microorganisms 3- Reduction to non-polluting N 2 , where the electron donors used are usually organic. However, due to the low content of organic matter in some industrial wastewa...

Problems solved by technology

However, the current electrode-biofilm method still has the problems of low mass transfer efficiency and treatment rate when dealing with high-concentration NO exhaust gas, and further improvement of electrode materials and reactor structure is needed.
