Description

Intelligent PAM automatic medicine adding device

Technical Field

The invention relates to the field of PAM dosing, in particular to an intelligent PAM automatic dosing device.

Background

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

Raw water purification principle is that raw water generally contains various suspended particles, colloid substances and other impurities. PAM is used as a flocculating agent, and the particles are coagulated into larger flocs through the interaction of active groups on a polymer chain and charges on the surfaces of suspended particles. Meanwhile, the long-chain structure of PAM can bridge a plurality of particles together to accelerate the sedimentation of the particles, thereby achieving the purpose of purifying water quality;

In sewage treatment, PAM also utilizes flocculation effect to form large flocs of suspended solids, colloid substances and some flocculable organic matters in sewage, so that the PAM is conveniently separated from the sewage by precipitation or air floatation and other methods. For some sewage containing fine particles or pollutants which are difficult to precipitate, the addition of PAM can obviously improve the precipitation performance and the sewage treatment efficiency;

The sludge treatment principle is that the sludge is solid waste generated in the sewage treatment process and contains a large amount of water and organic substances. PAM changes the structure and property of the sludge by flocculation with the granular substances in the sludge, reduces the hydrophilicity of the sludge, and ensures that the water in the sludge can be separated more easily under the action of mechanical pressure or natural gravity;

In the deep water treatment process with high water quality requirement, such as reverse osmosis pretreatment, ultrafiltration and the like, PAM can be used as a pretreatment medicament to remove tiny particles and colloid substances in water, prevent the tiny particles and colloid substances from causing blockage and pollution in subsequent treatment equipment, and prolong the service life of the membrane and improve the treatment effect.

However, no matter which application is used, the PAM dosage needs to be controlled when the specific application is added, so that the condition that the corresponding treatment standard cannot be met or secondary pollution is caused to the water body is avoided. At present, PAM is prepared into a solution reagent by a manual weighing mode, and then is added. However, the manual weighing preparation is low in efficiency and easy to cause large concentration precision errors of prepared solution. Therefore, an intelligent PAM automatic dosing device is provided.
