Porous medium filter bed suspended particle blockage form visualized analysis system

Abstract

The invention discloses a porous medium filter bed suspended particle blockage form visualized analysis system. The porous medium filter bed suspended particle blockage form visualized analysis system is characterized by comprising a porous medium filter bed, an LED light-emitting board assembly connected to the rear side of a bed body, a water supply assembly connected to the left side of the porous medium filter bed, a water collecting assembly connected to the right side of the porous medium filter bed, and a high-definition camera arranged on the front part of the porous medium filter bed. The porous medium filter bed is adopted so that the blockage phenomenon caused by suspension particles can be vividly studied, and blockage distribution and the blockage area can be directly calculated. Fluorescent powder is adopted for simulating suspension particles, luminescence is obvious, the area blocked by the suspension particles can be easily recognized, and the advantage of visualization is achieved compared with salt tracing and dye tracing. The porous medium filter bed suspended particle blockage form visualized analysis system is simple in structure, easy to use, relatively low in establishing and maintaining cost, and suitable for providing a measuring and managing scheme for controlling and reducing the blockage situation of the porous medium filter bed when the porous medium filter bed is designed and managed for treating wastewater.

Description

Technical field [0001] The present invention relates to the technical field of sewage treatment, and more specifically to a porous media filter bed suspended particulate matter (SS) blockage area distribution and blockage area analysis system, and also relates to a porous media filter bed suspended matter sedimentation blockage visual analysis system It is suitable for providing measures and management schemes to control and reduce the occurrence of clogging of porous media filter beds when designing and managing porous media filter beds to treat sewage. Background technique [0002] Because of its large specific surface area and certain flow capacity, porous media can provide sufficient growth space and attachment basis for microorganisms, and has become a commonly used filler in the treatment of sewage and wastewater. For example, constructed wetlands and biological filter beds are filled with porous media, and the microorganisms attached in the pores are used for biochemical t...

Problems solved by technology

However, the actual clogging form cannot be directly obtained by using the tracer method, and parameters such as short-circuit value and hydraulic efficiency can only be calculated indirectly through the tracer results to judge whether there is clogging in the porous media, nor can it intuitively give the state of the porous media filter bed. The distribution of blockage, the size of the blockage area, etc., have great limitations
