Abstract:
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.
