摘要
介绍了聚酰胺-胺(4.0G PAMAM)树形分子改性沸石的制备,并用制备的改性沸石处理实际印染废水。研究了改性沸石的投加量、作用时间、溶液的酸度、作用温度等对废水CODCr和色度去除率的影响。研究表明在最佳的试验条件下,印染废水的CODCr和色度去除率分别达到86.2%和93.7%。
The preparation of modified zeolite by PAMAM （4.0G） is introduced. The modified zeolite has been used for treating printing and dyeing wastewater. The effects of its dosage, time of reaction, pH of the solution, temperature of the reaction, etc. on the removal rates of CODcr and chroma of the wastewater are studied. The results show that under the optimum conditions, the removal rates of CODcr and chroma of the printing and dyeing wastewater research 86.2% and 93.7%, respectively.
