Abstract

The invention provides a papermaking wastewater treatment agent. The papermaking wastewater treatment agent is prepared from the following components in parts by weight: 40 to 50 parts of a triazinylacrylamide type ion copolymer, 20 to 30 parts of methoxytrimethylsiloxy substituted sorbitan ester, 10 to 15 parts of poly aluminum ferric chloride and 10 to 15 parts of carboxymethyl beta-cyclodextrin sodium salt. The invention further discloses an application method of the papermaking wastewater treatment agent; the application method comprises the following steps: putting the triazinyl acrylamide type ion copolymer, the methoxytrimethylsiloxy substituted sorbitan ester, the poly aluminum ferric chloride and the carboxymethyl beta-cyclodextrin sodium salt into papermaking wastewater; after stirring for 10 to 20 min, standing for 30 to 50min; then filtering to remove sediment and impurities so as to finish a treatment process. The papermaking wastewater treatment agent prepared by the invention has the advantages of more remarkable treatment effect, smaller dosage, better wastewater treatment efficiency, safer and more environment-friendly utilization, no corrosion to equipment and simple application method.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a papermaking wastewater treatment agent. Background technique [0002] Papermaking is one of the important industries of the national economy, which provides a large number of products, taxation and employment opportunities for the society; but it is also one of the most serious environmental pollution industries, and the wastewater it produces contains a variety of organic compounds that are difficult to degrade Pollutants seriously pollute the environment, pose a threat to human health, and become a barrier restricting social development. Therefore, zero discharge of papermaking wastewater is a practical production technology that pays equal attention to water saving and pollution control. It has good economic benefits, as well as obvious social and environmental benefits. It is also a necessary choice for the paper industry to achieve sustainable development. ...
