Abstract

The invention discloses a laser bijective sensor for evaluating the return-washing effect of hollow fiber membranes. The laser bijective sensor comprises a laser transmitter and a laser receiver, wherein a transparent detection cube is arranged between the laser transmitter and the laser receiver; a round channel is arranged in the detection cube in a penetrating manner; an end opening of the round channel is connected with a connecting pipe. The laser bijective sensor disclosed by the invention is applicable to evaluation on the return-washing effect of all membrane components, and is small in volume and convenient in installation; compared with other monitoring equipment, the laser bijective sensor is extremely low in cost, simultaneously has a waterproof function and can be fixed on a series of positions such as a flat ground and a membrane shell by adjusting a bracket; the position of return-washing solution in the component can be directly observed by signals, and return-washing parameters can be rapidly controlled, so that not only is the energy utilization efficiency improved, but also the return-washing effect is improved; the possibility of instantaneous adjustment for thereturn-washing parameters can be achieved.

Description

technical field [0001] The invention relates to a laser double-shot sensor used for evaluating the backwashing effect of a hollow fiber membrane, and belongs to the technical field of membrane method water treatment. Background technique [0002] Membrane technology has been widely used in the field of drinking water and sewage treatment as a "water treatment technology in the 21st century". Promote it further. [0003] Backwashing of hollow fiber membrane modules has received widespread attention as a means to mitigate membrane fouling. However, in the actual application process, the membrane modules are generally closed, and the backwash effect can only be evaluated by the original flux recovery rate. For hollow fiber membrane modules, the axial length is much longer than The radial length, thus forming a unique hydraulic characteristic on the axial length of the membrane: along the axial direction of the hollow fiber membrane, its flow and pressure are characterized by ...
