废水中有机污染物的吸附治理研究
The adsorption of organic pollutants in wastewater
Abstract: In this paper, weakly polar macroporous resin processing wastewater containing organic pollutants, compared before and after adsorption of organic contaminants in wastewater compared analyzed by measuring the absorbance of the weak polar macroporous resin adsorption effect. Experimental studies have shown that weak polar macroporous resin adsorption performance is very good, polystyrene resin beads modified resins are also more suitable for wastewater treatment, and the modified conditions, the resulting resin showing regular changed. By means of spectrophotometry, infrared spectroscopy and other means of testing carried out under optimum conditions modified polystyrene resin ball factors affecting adsorption studies. The proposed use of methyl chloroacetate modified polystyrene resin beads used in sewage treatment methods, which can effectively remove organic pollutants in waste water solution. Using macroporous resin weakly polar organic pollutants in waste water treatment is also on the ideal methods.
