Description

Biomembrane simulation device and method based on multiple flow velocity calibration and temperature control optimization Technical Field The invention relates to the field of biomembrane simulation devices, in particular to a biomembrane simulation device and method based on multiple flow velocity calibration and temperature control optimization. Background A biofilm reactor (BAR) is a laboratory device used to simulate the effects of various water quality parameters and hydraulic conditions in a pipe network on pipe wall biofilms. The biological membrane reactor can be used for various researches on the development characteristics of biological membranes, the influence on water quality and the like. The reactor design is different according to different experimental purposes, the reactor main body is generally formed by sleeving an inner organic glass cylinder and an outer organic glass cylinder, the inner sleeve is filled with experimental water, water inlets and outlets are arranged on the upper portion and the lower portion of the sleeve, a rotor is arranged in the inner sleeve, the rotating speed of the rotor can be adjusted by a frequency converter during working, and the outer sleeve is filled with warm water to adjust the temperature of the experimental water in the inner sleeve. The traditional biofilm reactor design can meet most experimental requirements, but still has the following disadvantages and shortcomings: (1) The temperature in the pipeline has obvious influence on water quality, and the temperature influences the activity of microorganisms, so that the absorption and release of the microorganisms on elements such as carbon, nitrogen, phosphorus and the like in the water body are influenced, and therefore, the accurate regulation and control of the temperature is important. In the traditional design, the temperature of the outer sleeve is controlled to adjust the temperature of experimental water in the inner sleeve, but in the actual deep water pipeline engineering, the temperature of the pipe wall and the temperature of water flow are greatly different, so that an improved device is needed for accurate simulation, and the pipe wall temperature and the water flow temperature are controlled respectively. (2) When the flow speed of water flow in the pipeline is changed, the shearing force applied to the wall surface is changed, so that the structure of the biological film is influenced, the mass transfer efficiency of the biological film is changed, and the rotating speed control of the reactor is very important. At present, a frequency converter is generally adopted to regulate the rotating speed, a user needs to conduct unit conversion according to the flow speed of water flow in an actual water conveying pipeline (the rotating speed unit is r/s and the flow speed unit is m/s), and the method can not observe in real time and judge whether the rotating speed is accurately controlled. Therefore, there is a need for an intuitively controllable multiple flow rate calibration device. (3) In the traditional biofilm reactor design, hanging pieces are generally inserted into a rotary drum to simulate a tube wall so as to culture a biofilm, and in the mode, a sample is scraped and taken for microorganism detection, so that the structure and the shape of the biofilm are inevitably damaged during operation, and the overall view is difficult to observe. In addition, the method can only simulate one pipeline material at a time, and can not acquire experimental data of a plurality of groups of pipeline wall materials at the same time.
