Abstract

A method and equipment for in-line detecting the flocculated state in water treatment is disclosed. Said method includes such steps as arranging a lamp box and a CCD camera at both sides of a transparent flocculation subsider, taking the optical signals of flocculate, converting them to electric signal, A / D conversion, inputting the digital signals to computer, processing to obtain image information, and analyzing.

Description

Technical field: [0001] The invention belongs to a water treatment dosing detection technology. Background technique: [0002] Flocculation is the most important process in the water treatment system, and it is also the most difficult link to manage. The online detection technology of flocculant dosing determines whether the flocculant can be accurately dosed and controlled, which in turn affects the operation status and efficiency of the water treatment process, and directly affects the water quality of drinking water. The flocculation process exhibits high-dimensional complexity, ambiguity, contingency and incompleteness of system information. At present, there is still a lack of powerful means for online detection and analysis and quantitative description. In the past research, most of the flocculation system was regarded as a "black box", and only the input of flocculant and the output of the flocculation effect were taken into account. Even if the microscopic process w...
