Abstract

The invention discloses a coagulation picture shooting device which comprises a stirrer, a reaction container and a lifting platform which are sequentially arranged from top to bottom, a high-speed camera is arranged on one side of a transparent container, and a plane light source is arranged on the other side of the reaction container; and the industrial high-speed camera is mounted on the bracket. The device is used for shooting a coagulation picture of a water sample added with a coagulant. The invention further discloses a coagulation picture shooting method and a dosing method for controlling flocculation through machine learning. According to the dosing method, flocculation images of different water qualities are classified and identified, and a function relationship between the water quality and the dosing amount of the flocculating agent is established, so that accurate dosing of the flocculating agent is realized.

Description

technical field [0001] The invention belongs to the technical field of water treatment dosing, and in particular relates to a coagulation picture taking device, a coagulation picture taking method, and a machine learning controlled flocculation dosing method. Background technique [0002] Flocculation dosing is an important link in the field of water treatment. The accuracy of the filling amount is directly related to the quality of effluent water and production costs, but it is difficult to achieve precise dosing of flocculants. In the current market, the online flocculation control process mainly includes The following aspects: [0003] First, use the flowing current as the monitoring signal to realize online dosage control. By detecting the magnitude of the conductive current of the water body after dosing, it is used as a control signal to adjust the frequency converter of the metering pump, thereby controlling the amount of flocculant dosage and keeping the conductive ...
