Device and method for achieving accurate in-situ monitoring of dynamic changes of substance concentration in biomembrane of rotary-type biomembrane reactor

Abstract

The invention discloses a device and method for achieving accurate in-situ monitoring of dynamic changes of the substance concentration in a biomembrane of a rotary-type biomembrane reactor.The device comprises a carrier sheet, a vessel for containing a solution, a peristaltic pump, a lifting mechanism and a microelectrode, and the carrier sheet is installed on a support frame and used for containing the biomembrane; the vessel and the peristaltic pump are installed on the lifting mechanism, and the vessel is located under the carrier sheet; the peristaltic pump is communicated with the vessel through a pipeline so as to enable liquid in the vessel to flow; the lifting mechanism and the peristaltic pump are connected with a control system, the microelectrode is connected with a processing unit, and a collected signal is processed through the processing unit.According to the device and method for achieving accurate in-situ monitoring of the dynamic changes of the substance concentration in the biomembrane of the rotary-type biomembrane reactor, different reactor rotating speeds, immersion rates, main solution properties and the like can be simulated, an operating state similar to that of the biomembrane in the rotary-type biomembrane reactor can still be achieved on the condition that the biomembrane is fixed, and therefore the dynamic changes of the substance concentration in the biomembrane can be accurately monitored.

Description

technical field [0001] The invention relates to a dynamic monitoring method, in particular to a device and method for quasi-in-situ monitoring of the dynamic change of substance concentration in a biofilm of a rotary biofilm reactor, and belongs to the field of dynamic monitoring of microscopic substance concentration. Background technique [0002] The biofilm method is two commonly used sewage biological treatment methods that coexist with the activated sludge method. It has the characteristics of strong impact load resistance, small footprint, large biomass, and is suitable for the growth of microorganisms with a long generation cycle. It is especially advantageous when it is difficult to treat wastewater with large fluctuations, high organic matter, and high nitrogen and phosphorus. With the deepening of research on biofilms, in order to study the internal metabolic mechanism of biofilms, it is necessary to monitor the changes in the concentration of microscopic substance...

AI Technical Summary

Problems solved by technology

In the existing research, some scholars took out the biofilm and placed it in the air or solution for monitoring, but this practice destroyed the alternate exposure environment in which the biofilm grew normally, and could not truly reflect the biological environment. Changes in Membrane Properties as it Operates in a Reactor

Some scholars have also used the method of periodically injecting and draining liquid into the container where the biofilm is placed to provide an alternate exposure environment for the biofilm, but the main solution is still at each measurement, which fails to simulate the relationship between the biofilm and the biofilm under real operating conditions. The relative movement of the main solution, the research results are still quite different from the real situation
