Selection of polyaluminium chloride to purify industrial paper wastewater process

2025-04-01
In the rapid development of industry together, how to deal with all kinds of sewage, reduce the pollution of the environment seems to be the main. In such as: adsorption, ion exchange, redox, sedimentation, activated sludge, biofilm and other water treatment methods, flocculation and deposition of sewage treatment with polyaluminium chloride is more widely used, the cost is relatively low-cost approach. In this method, the core and key role is the selection and application of poly aluminium chloride. 1、Ordinary sewage treatment Polyaluminium chloride has a very good processing effect, especially solid polyaluminium chloride can be very good treatment of washing wastewater. Because, solid polyaluminium chloride can deal with many oil, dust particles contained in the scrubbing wastewater agilely, only need to put in a certain amount of solid polyaluminium chloride, can make the appearance of the particles of the strong adsorption of electric neutralization can occur, can occur quickly adsorption of pollutants in the water quality, and then purify the water quality of the role. Usual sewage polyaluminium chloride is more suitable for the amount of input. Polyaluminium chloride is earthy yellow (powder), bright (liquid), polyaluminium chloride practice is a kind of alumina, because of the mixture of aluminium chloride, its deposition is mainly aluminium hydroxide chloride AL (OH) 2 deposition, which is a kind of glue can be wrapped up in the water impurities in its inside or attached to its appearance, the more the more heavy and deposition down to make the water clear. The dosage of liquid 1000M3 water, while the solid 9-10kg can be. 2、Industrial paper wastewater treatment Poly aluminium chloride often plays a very important role. First of all, industrial wastewater is not the same as ordinary daily sewage, the content of pollutants in the water quality has substantial differences, and therefore in the selection of polyaluminium chloride to purify the water, the selection of commodities with the daily sewage has a very big difference. Coagulation and deposition with polyaluminium chloride treatment of paper middle water, with the increase of salinity, COD and SS removal rate increased. It should be noted here that, after 75% of the salinity, the removal rate turns to decrease. At a temperature of 250℃, adding 0.6gL of polyaluminium chloride with a salinity of 75% can make the effluent meet the discharge standard. Polyaluminium chloride in alkaline (pH 7-9) conditions, when the coagulant dosage is greater than 750mgL, the suspended solids removal rate can reach more than 95%, and can remove 20-50% of CODCr. With polyaluminium chloride to deal with industrial paper sewage, but also has a low price, the use of good, will not form a secondary pollution of the water quality and other conditions, which is many paper industry to choose polyaluminium chloride to purify the water quality of one of the main reasons. 1319399021 The main products of flocculant manufacturer Xinhuan Water Treatment are: White polyaluminium chloride (food grade), drinking grade polyaluminium chloride, industrial grade polyaluminium chloride, anionic polyacrylamide, cationic polyacrylamide, nonionic polyacrylamide, petroleum recycling polyacrylamide, oil recovery polyacrylamide, polyacrylamide, polymer flocculant polymer flocculation coagulant, polymeric ferrous sulphate, polymerized iron and aluminium chloride, and other water treatment chemicals.
