Abstract

The invention discloses a water purifying agent for coking wastewater treatment and a preparation method thereof. The water purifying agent comprises a modified polyacrylamide adsorbent inner core, and carbon quantum modified on the modified polyacrylamide adsorbent inner core. points and a protective layer covering the outside of the polyacrylamide core. In view of the characteristics of complex components and difficult treatment of wastewater in coking and other industries, the present invention provides a new type of adsorption material as a water purifier, which has high adsorption efficiency for various heavy metal ions and organic substances, and can be used very well It is suitable for the purification treatment of coking wastewater; the water purifying agent of the present invention uses a modified polyacrylamide adsorbent as the core, and modifies carbon quantum dots with rich functional groups on the surface, which can greatly improve the adsorption performance of zwitterionic polyacrylamide The present invention can further prevent deliquescence of the adsorbent by coating the protective layer outside the adsorbent, prolong the shelf life of the water purifier, and further enhance the use effect of the water purifier.

Description

technical field [0001] The invention relates to the field of wastewater treatment agents, in particular to a water purifying agent for coking wastewater treatment and a preparation method thereof. Background technique [0002] With the rapid development of industry, the problem of environmental pollution has gradually become prominent. Water is the most basic living resource for human beings. The process of industrial development has brought many water pollution problems, and the treatment of industrial wastewater is urgent. For example, the coking wastewater produced in the production of coking plants is a kind of industrial wastewater with serious pollution and complex composition. Coking wastewater is produced during coking and coal gas high-temperature dry distillation, purification and by-product recovery process, which contains a variety of organic substances (such as alcohols, phenols, amines, etc.) and a large number of heavy metal ions (such as Ag + , Pb 2+ 、Cd ...
