Abstract

The invention relates to a treatment agent for papermaking wastewater and a preparation method thereof. The treatment agent for papermaking wastewater comprises the following components in parts by weight: 10-20 parts of a flocculating agent, 3-8 parts of a surfactant, 15-25 parts of activated carbon, 7-15 parts of bentonite and 5-10 parts of a carbon nanotube / polyacrylamide composite material. Apreparation method of the carbon nanotube / polyacrylamide composite material comprises the following steps: dispersing functional carbon nanotubes in an organic solvent, adding polymerizable glycidyl ether, acrylamide and an initiator, introducing nitrogen to replace air in a bottle, carrying out a stirring reaction in an oil-bath pan at 60-70 DEG C for 2-3 h, carrying out reduced-pressure distillation to remove the solvent after the reaction ends, drying a solid in vacuum, and conducting grinding to obtain the carbon nanotube / polyacrylamide composite material. The treatment agent for papermaking wastewater is simple in treatment process, BOD and COD in water can be effectively reduced, treatment time is short, treatment effect is good, and the quality of treated water can reach a dischargestandard.

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to a papermaking wastewater treatment agent and a preparation method thereof. Background technique [0002] The wastewater produced in the production process of the paper industry contains a large amount of organic and inorganic substances, which seriously endangers the living environment of aquatic organisms, plants and human beings, and destroys the utilization value of water resources. The methods of papermaking wastewater treatment include: physical method, chemical method, physicochemical method and biochemical method, etc. At present, many papermaking industries at home and abroad choose to use chemical oxidation method and flocculation precipitation method to remove pollutants in papermaking wastewater. [0003] With the rapid development of the economy, the paper industry is also showing a trend of blowout development. Correspondingly, the types, discharge volume and comp...
