1PAM can make suspended matter neutralize by electricity, bridging adsorption and flocculation.
2 It can play a bonding role through mechanical, physical and chemical effects.
3PAM can effectively reduce the frictional resistance of the fluid, and adding a small amount of PAM to the water can reduce the resistance by 50-80%.
4: PAM has a thickening effect under neutral and acid conditions, and when the pH value is above 10, PAM is easy to hydrolyze. Thickening will be more pronounced in a semi-reticular structure.
Instructions for the dosage of polyacrylamide
1. The amount of cationic polyacrylamide used for coal washing can be set between 30 kg and 110 kg; the amount of wastewater used in the chemical industry is generally between 50 and 120 kg; the amount of wastewater used in the bleaching and dyeing industry The waste water in the paper industry is the most difficult to treat, and the amount used should be increased. It is reasonable to set the amount used at 100 to 300 kilograms. Generally, the electroplating wastewater industry and ordinary industrial water should not exceed 50 kilograms. Note: (The amount used in these industries is the amount of wastewater per thousand tons).
2. The flocculants used for desliming of domestic sewage are different according to different treatment methods.
If the main body of the process adopts the biochemical method, that is, the dewatering of the excess sludge (which may contain part of the primary sludge), only cationic PAM is needed as the sludge dewatering agent.
If the main body of the process adopts physicochemical methods, such as primary strengthening, loading magnetic separation, etc., it is generally first to add PAC for conditioning, then add anionic flocculant, and finally add cationic flocculant for dehydration. The specific dosage depends on the quality of the sewage.
There are also many sewage treatment stations. PAC or other inorganic flocculants can be directly added to sludge dewatering. This is widely used in plate and frame filter presses, especially in electronic factories or small sewage treatment stations.
When PAM is used as a sludge dewatering agent, the ratio of PAM to water is generally between 0.1% and 0.2%. After dissolving into a glue-like liquid, it is then added to the sludge for mixing.
The ratio with sludge is generally 5%--10%, and some are lower. This should be determined according to the concentration of sludge. It is best to determine the optimal dosage and use model through on-site beaker experiments. Different sludges, different chemicals, different equipment, and different management levels have different sludge treatment effects.
3. The sewage treatment plant uses cationic polyacrylamide as the sludge dewatering agent for sewage operation. In the process of communicating with customers, customers often ask about the amount of sludge dewatering agent added in the process of sludge dewatering in sewage treatment. To know the amount of sludge dewatering agent relatively accurately, first of all, understand these parameters, the moisture content of the sludge, the moisture content of the mud cake, the amount of mud, the amount of medicine, the concentration of the preparation, etc.
Sludge moisture content: The percentage of the weight of the moisture contained in the sludge to the total weight of the sludge is called the sludge moisture content.
Moisture content of mud cake: The percentage of the ratio of the weight of the moisture content of the mud cake to the total weight of the sludge is called the moisture content of the mud cake.
The following formulas are also used to calculate
1. Dosing amount mg/L = dosing quality / treated water volume / dispensing concentration
2. Dosing amount of treated water = treated water m3/h * dosing amount g/m3
3. Amount of dry mud = amount of treated water * [(1-moisture content of sludge)/(1-moisture content of mud cake)]
4. The consumption of chemicals per ton of dry mud is g/m3 = the amount of drug added/the amount of dry mud
The error of the above calculation results may be relatively large, and it is only used for reference during sewage operation. The actual drug consumption should be tested in actual machine operation.
Polyacrylamide is a linear organic polymer, but also a polymer water treatment flocculant products, specifically can adsorb suspended particles in water, between the particles to play a role in linking bridges, so that fine particles form a relatively large floc, and accelerate the speed of precipitation. This process is called flocculation because of its good flocculation effect PAM as a flocculant for water treatment and is widely used in sewage treatment.Anionic polyacrylamide (APAM) is a water-soluble polymer, mainly used for flocculation and sedimentation, sedimentation and clarification of various industrial wastewaters, such as iron and steel plant wastewater, electroplating plant wastewater, metallurgical wastewater, coal washing wastewater, etc. Mud dehydration, etc. It can also be used for drinking water clarification and purification.
