Description

TECHNICAL FIELD

[0001] The utility model relates to gravity sedimentation observation equipment manufacturing technical field, especially relate to fixed multistage water treatment gravity sedimentation process characterization equipment. BACKGROUND

[0002] Gravity sedimentation is an important operation in water treatment process, specifically refers to the process that makes the solid particles suspended in fluid under the action of gravity and separates from fluid, its principle is to rely on the earth's gravitational field, utilizes the density difference between dispersed phase and continuous phase, makes it produce relative motion and produces sedimentation.

[0003] In various water treatment processes, gravity sedimentation is a common solid-liquid separation measure and unit operation, and is an indispensable effective means to realize solid-liquid separation, and its efficiency will directly affect the subsequent water treatment effect and efficiency. At the same time, a large amount of sedimentation experiments and evaluation work need to be carried out for sedimentation structure design, coagulant dosage calculation, related treatment unit debugging, therefore, it has practical basis and value to evaluate the gravity sedimentation performance of particles and analyze and study the gravity sedimentation process of water treatment.

[0004] The sedimentation column observation method is the most traditional and widely used method for studying gravity sedimentation process in waterworks, sewage treatment plants and laboratories. For example, when studying the sedimentation performance of activated sludge, a cylinder or a measuring cup with a volume of one liter or several liters is used, the activated sludge suspension is added and left to stand, and the sedimentation process and the change of solid-liquid interface are observed.

[0005] In the above-mentioned sedimentation column observation method, the sedimentation process in the sedimentation column is generally judged, compared and image data is collected by naked eye or camera. Due to the existence of certain differences in auxiliary equipment and instruments, this method is easy to produce errors, such as the difference in shooting by different experimenters, or the difference in shooting angle and relative distance at different times, the difference between sedimentation columns, etc. will cause errors, and these errors will affect the accuracy and relative accuracy of the characterization analysis of gravity sedimentation experiment, and affect the characterization analysis conclusion.

[0006] In addition, the traditional camera adopts a single direction mode, and the sedimentation behavior and image are mainly observed from one angle.

[0007] Therefore, accurate observation or shooting has important influence on the study of sedimentation, especially when particle image velocimetry (PIV) and non-intrusive image analysis (NIA) methods are used for observation and shooting, the quality of the photographed pictures or images will directly affect the determination of sedimentation particle velocity, morphology and analysis characterization and comparison.

[0008] Therefore, it is particularly important to accurately control the shooting characterization conditions and obtain comparable and uniform condition sedimentation characterization images in the sedimentation column observation method.
