Waste water treatment agent of polyacrylamide polymer coagulant applications
Drum tower district wastewater treatment agent polyacrylamide polymer flocculant application field, flocculant application field widely.
The use of the flocculant, the inorganic flocculant flocculation sedimentation is chosen (polyaluminium chloride) and organic flocculants polypropylene acyl ammonium mixture in aqueous solution to join wastewater, will produce compressed double electric layer, make the waste water in aerosols lose stability, colloidal particles condensed particles increase each other, forming the flocculation body, the alum flowers.
Adding flocculant polymer coagulant in the treatment of refinery wastewater is to make the water and quick, thorough separation of impurities.
High polymer flocculant areas of application:
One, the polyacrylamide with isolated from urban sewage has flocculation, the degradation efficiency of the mixed bacteria sewage processing, can make the sewage COD and BOD removal rate reached 100%.
Second, mainly used in industrial solid-liquid separation process, including settlement, clarification, concentration and sludge dewatering technology, application of the main industries are: urban sewage treatment, paper industry, food processing, petrochemical industry, metallurgical industry, mineral processing industry, dyeing industry and sugar industry and all kinds of industrial wastewater treatment. Used in urban sewage and meat, poultry, food processing wastewater treatment process of sludge precipitation and sludge dewatering by its organic colloid electrical group of sludge negative charge neutralization and excellent polymer bridging coagulation function, prompting colloid particles gathered into large pieces of floc, separated from the slurry. Obviously, dosing quantity is little.
Three, in the paper-making industry can be used as paper dry strength agents, retention agent, filter aid, can greatly improve the quality of the paper, cost savings, improve the production ability of paper mill. Can be directly with inorganic salt ions, fiber, and other organic polymer electrostatic bridge so as to enhance the physical strength of paper, and reduce the loss of fiber or filler to accelerate the filtering, enhancement and retention, leaching effect, can also be used for water treatment, at the same time, in the deinking process can a obvious flocculation effect.
Four, fiber slurry (asbestos cement products) can make the shape of asbestos and cement products and improved drainage, increase the intensity of the slab material asbestos; In the insulation board, can improve the ability of the combination of the additive and fiber.
Five, can be used for dyeing wastewater, leather wastewater, oily wastewater treatment, except turbidity, decolorization, to achieve the emission standards.
Polyacrylamide flocculant is widely applied in thickening, stable colloid, drag reduction, binding, film, biomedical materials and so on. In water treatment as a coagulant aid, flocculants and sludge dehydrating agent. Water as a drop in oil drilling, oil displacement agent. As retention aid in papermaking process, reinforcing agent.
