Cationic polyacrylamide dissolution and use method:

Cationic polyacrylamide is a white solid powder, belongs to the organic polymer flocculant, high viscosity, in the process of sewage and sludge treatment when used, need to put the solid powder polyacrylamide dissolved into a certain concentration of liquid, the use of polyacrylamide aqueous solution for sewage treatment, sludge pressure filtration dehydration,

The dissolution method and use method of cationic polyacrylamide are as follows:

1, cationic polyacrylamide dissolution: to use clean tap water dissolution, can not use sewage, the normal temperature of water dissolution can be, water temperature is less than 5℃, the dissolution rate is slow, you can increase the dissolution rate by heating, but not more than 40℃, water temperature is too high will lead to polymer degradation, affect the use effect.

2, polyacrylamide concentration configuration: one thousand to three thousand, 1 liter of water add 1-3 grams of solid polyacrylamide. In the configuration process, the concentration of liquid agent can be lower, which is more conducive to the mixing of polyacrylamide flocculant solution and sewage, forming a more dense and larger alum flower, producing good flocculation effect and improving the efficiency of sewage treatment.

3, polyacrylamide concentration configuration reference factors: if the configuration of solubility tank is small, large capacity, it is recommended to configure 0.3% concentration of liquid; If the selection of polyacrylamide molecular weight is high, can be configured with 0.1% concentration of liquid; Polyacrylamide solution is added to the sewage, if because of equipment reasons, the dispersion is not in place to better mix with sewage, the solution concentration can be lower to ensure that the load of the stirring equipment is moderate when dissolving, and the flocculant is better mixed with sewage. Do not use centrifugal pumps to transfer the finished solution to avoid shear degradation of the polymer caused by high-speed rotating blades.

4, solid polyacrylamide solution configuration method: add quantitative water in the solution tank, according to the water and concentration of solid polyacrylamide calculation required by weight, weighing agents. Turn on the electric stirrer and stir the water out of the whirlpool. The linear speed at the end of the stirrer blade should not exceed 8 m/s to avoid polymer degradation. The stirring speed should not be too slow, so that the polymer particles do not float on the surface of the water, or sink in the water, clumping. Add solid polyacrylamide to the vortex in the water, pay attention to powder polyacrylamide particles into the water after dissolution can not adhere to each other, agglomeration. Stir the polyacrylamide thoroughly to dissolve it into a uniform, transparent and viscous solution without visible snowflake lumps.

5. Mixing time is determined according to the following method:

(1) in summer when the water temperature is high, negative and cationic polyacrylamide need to stir 45-60 minutes, non-ionic polyacrylamide need to stir 60-90 minutes;

(2) in winter when the water temperature is low, negative and cationic polyacrylamide need to stir for about 60 minutes, non-ionic polyacrylamide need to stir for about 3h.

6, the selection of drug dissolution device: tank to avoid the use of iron containers, iron ions are caused by all the polyacrylamide chemical degradation catalyst, in the preparation, transfer, storage of polyacrylamide solution, to avoid iron ions into. The equipment in contact with the solution is made of stainless steel, plastic, fiberglass or carbon steel coated with resin.

7, cationic polyacrylamide additive use: cationic polyacrylamide after dissolved into solution in sewage treatment through dosing system into flocculation pool, if used to dissolve in the process of sludge dewatering processing good reagent solution dosing in sludge thickener, enhance sludge concentration, flocculant are researched, and then press filter for pressure filtration dehydration. If cationic polyacrylamide is used for sewage treatment, the agent solution should be fully mixed with sewage to form flocculation reaction. General polyacrylamide and PAC polyaluminum chloride, PFS polyferric sulfate, PAFC polyaluminum chloride, aluminum sulfate and other inorganic coagulants with the use. Take polyaluminum chloride as an example of inorganic coagulant added in the coagulation tank, through hydraulic automatic mixing of suspended solids and PAC polyaluminum chloride to generate charge neutralization, loss of stability, the formation of small alum flower, after the treatment of the sewage after the coagulation tank into the flocculation tank after adding PAM polyacrylamide, further help coagulation. It helps the small flocs that have formed alum flowers to form larger flocs, which are separated from water under the action of gravity and form precipitation. The water flow after flocculation enters the sedimentation tank for further mud water separation and sludge concentration treatment.

8, negative and cationic polyacrylamide solid and liquid agents can not be mixed together, mixing can not be used to achieve sewage sludge treatment effect.

40 ion degree cationic polyacrylamide packaging and storage:

Cationic polyacrylamide packing 25 kg/bag, plastic moisture-proof film, kraft paper covered bag, can avoid polyacrylamide moisture.

Storage polyacrylamide solid dry powder products do not expose for a long time, will lead to damp agglomerate, should be stored in a cool and ventilated dry place.

40 ion degree cationic polyacrylamide main uses:

Industrial organic sewage, sludge purification treatment will often use cationic polyacrylamide as flocculant, coagulant aid, according to the ionic degree model to distinguish cationic polyacrylamide has 15 degrees, 20 degrees, 30 degrees, 40 degrees, 50 degrees, 60 degrees several ions, In the effective PH range for sewage treatment, sludge dewatering application effect is very ideal. The specific application of cationic polyacrylamide is mainly in the following aspects:

1, sludge dehydration: Urban sewage and domestic sewage and industrial sewage activated sludge method is commonly used treatment, biochemical sludge is hydrophilic suspension colloid, the high content of organic matter, organic matter and water separation, need to do with cationic polyacrylamide flocculating agent, additive to the sewage or sludge, mud separation, after the solid-liquid separation of sediment, Sludge dewatering is carried out by sludge dewatering machine. Cationic polyacrylamide used in sewage sludge dewatering treatment is characterized by less dosage of agents, high sludge dewatering efficiency, easy to sludge solid-liquid separation.

2, papermaking industry, the application of cationic polyacrylamide in papermaking industry, mainly do the papermaking retention and filtration aid, can direct and inorganic salt ions, fiber and other organic polymer electrostatic bridge, strengthen the result of the paper strength and flexibility, and reduce the loss of fiber or cationic packing, to speed up the filter water, have the effect of enhancement, retention, leaching. Papermaking industry wastewater treatment, mainly papermaking white water treatment, in the process of deinking flocculation precipitation, with PAC polyaluminum chloride and PAM polyacrylamide used to treat papermaking industry wastewater, paper mill sludge dewatering treatment using PAM polyacrylamide.

3, industrial sewage and organic wastewater treatment: Cationic polyacrylamide in acidic or alkaline medium is electropositive, negatively charged with suspended solids in the wastewater of sewage processing, flocculation precipitation and clarification effect is very ideal, such as the pharmaceutical wastewater, starch factory waste water, brewery wastewater, alcohol plant wastewater and gourmet powder factory wastewater, sugar refinery wastewater, meat factory waste water, beverage factory waste water, Textile printing and dyeing plant wastewater, livestock wastewater, urban sewage plant, domestic sewage purification treatment.
