Abstract

The present invention is one infrared proportional pulsation detecting device and method for flock state in water and belongs to the field of optical detection technology for flock state in water treatment. The infrared proportional pulsation detecting device includes transmitted light detector inside the No. 2 window, infrared source inside the No. 1 window opposite to the transmitted light detector, and scattered light detector inside the No. 3 window perpendicular to the infrared source. The electric signals the transmitted light detector and the scattered light detector output are converted into digital signal in the A/D converter, and the digital signal is processed in the microprocessor to obtain the flock state number signal output via the communication interface. The present invention has less investment and high effect, and is especially suitable for use in controlling the throwing of flocculant in water treatment.

Description

Technical field: [0001] The invention belongs to a floc morphology optical detection device and method applied to the flocculation dosing process of water treatment. Background technique: [0002] Flocculation is the most important treatment process in the water purification system, and it is also the main component of the cost of water production. The accuracy of flocculant dosage directly affects the whole process of water treatment. The traditional flocculation dosing detection and control technology mainly includes: the mathematical model that needs to detect various apparent parameters that affect the flocculation effect (flow rate, turbidity, pH value, alkalinity, temperature of raw water, flow rate, concentration, efficiency, etc. of coagulant) method, a simplified method that only detects some parameters, a semi-automatic method that detects one or two parameters above, a model filter method or a model inclined tube method, etc. They all have insurmountable shortcom...
