Abstract

The invention relates to the technical field of wastewater treatment, and in particular relates to a papermaking wastewater treating agent and a preparation method thereof. The papermaking wastewater treating agent comprises the following raw materials in parts by weight: 2-10 parts of ferrous sulfate, 10-20 parts of magnesium sulfate, 0.5-1.5 parts of polyacrylamide, 15-25 parts of ferric nitrate, 1-5 parts of nickel nitrate, 35-50 parts of polyaluminum chloride, 15-30 parts of starch xanthate, 2-5 parts of tetrasodium 2-phosphonobutane-1, 2, 4-tricarboxylate, 0.5-1 part of zinc sulfate, 1-3 parts of benzotriazole, 16-30 parts of modified kieselguhr, 5-20 parts of cross-linked rectorite and 5-8 parts of a chitosan-graphene composite material. The papermaking wastewater treating agent disclosed by the invention is wide in using range, simple in treatment process, small in drug consumption, good in treatment effect, stable in performance and good in effluent quality and is capable of effectively reducing the cost of water treatment, so that the papermaking wastewater treating agent has a very good economic benefit and a wide social benefit.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a papermaking wastewater treatment agent and a preparation method thereof. Background technique [0002] Papermaking wastewater mainly comes from the two production processes of pulping and papermaking in the papermaking industry. Pulping is to separate the fibers in plant raw materials, make slurry, and then bleach it; papermaking is to dilute, shape, and Pressed, dried, and made into paper. These two processes all discharge a large amount of wastewater, and the wastewater produced by pulping is the most polluted. The wastewater discharged during pulp washing is dark brown, which is called black water. The concentration of pollutants in black water is very high, with BOD as high as 5-40g / L, containing a large amount of fiber, inorganic salts and pigments. The wastewater discharged from the bleaching process also contains a large amount of acid and alkali substances. ...
