Description

TECHNICAL FIELD

[0001] The application relates to the field of PAM dosing, in particular to an intelligent PAM automatic dosing device. BACKGROUND

[0002] PAM (polyacrylamide) is widely used in water treatment, mainly as a flocculant for the following aspects:

[0003] Raw water purification principle: raw water usually contains various suspended particles, colloidal substances and other impurities. As a flocculant, PAM interacts with the charges on the surface of suspended particles through the active groups on its polymer chain, making the particles coagulate into larger flocs. At the same time, the long chain structure of PAM can bridge multiple particles together, accelerating the settling of particles, thereby achieving the purpose of purifying water quality;

[0004] Sewage treatment principle: in sewage treatment, PAM also utilizes its flocculation effect to make suspended solids, colloidal substances and some flocculable organic matters in sewage form large flocs, which can be easily separated from sewage by methods such as sedimentation or air flotation. For sewage containing small particles or difficult-to-settle pollutants, the addition of PAM can significantly improve the sedimentation performance and improve the efficiency of sewage treatment;

[0005] Sludge treatment principle: sludge is a solid waste produced in the process of sewage treatment, containing a large amount of water and organic matter. PAM changes the structure and properties of sludge by flocculating with the particulate matter in the sludge, reducing the hydrophilicity of the sludge, so that the water in the sludge can be more easily separated under mechanical pressure or natural gravity;

[0006] Advanced water treatment principle: in some advanced water treatment processes with high water quality requirements, such as reverse osmosis pretreatment and ultrafiltration, PAM can be used as a pretreatment agent to remove small particles and colloidal substances in water, prevent them from causing blockage and pollution in subsequent treatment equipment, and improve the service life and treatment effect of the membrane.

[0007] However, regardless of the above uses, the amount of PAM needs to be controlled during specific use and addition to avoid failing to meet the corresponding treatment standards or causing secondary pollution to the water body. Currently, PAM is used by manually weighing it to prepare a solution reagent, which is then added. However, manual weighing preparation is not only low in efficiency, but also prone to large concentration precision errors in the prepared solution. Therefore, an intelligent PAM automatic dosing device is proposed. SUMMARY
