Abstract

The invention discloses a cyclodextrin modified polyacrylamide sewage treatment agent. The cyclodextrin modified polyacrylamide sewage treatment agent is prepared from the following raw materials in parts by weight: 60-70 parts of acrylamide, 1.5-2 parts of dibenzoyl peroxide, 4-6 parts of cyclodextrin, 0.6-1 part of calcium acetylacetonate, 90-100 parts of kieselguhr, 2-4 parts of trimethylolpropane, 1-2 parts of aluminum potassium sulfate, 1-2 parts of sodium diacetate, 9-10 parts of polyvinylpyrrolidone and 2-3 parts of stearic acid. Cyclodextrin modified treatment is adopted to further improve the adsorption stability of a finished product treatment agent; and the material disclosed by the invention has good safety and environmental friendliness and superior comprehensive properties.

Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to a cyclodextrin-modified polyacrylamide sewage treatment agent and a preparation method thereof. Background technique [0002] my country is a country with serious shortage of water resources and serious waste of water resources. With the rapid urbanization process, the pollution of urban industrial wastewater and domestic wastewater is becoming more and more serious. It is particularly important to strengthen sewage treatment, especially industrial wastewater treatment. According to statistics, my country's annual discharge of industrial wastewater is about 8 × 10 8 m 3 , which not only contains highly toxic ingredients such as cyanide and chlorophenol, but also contains metal ions such as chromium, zinc and nickel. There are many ways to treat wastewater, mainly chemical precipitation, electrolysis and membrane treatment. Chinese patent CN201210230579.1 dis...
