泥炭对印染废水的脱色处理研究

研究了泥炭对模拟印染废水的脱色处理问题，探讨了各种因素对脱色效果的影响。实验结果表明：在较宽的pH值范围内，泥炭均表现出良好的脱色性能，在加入量分别为80mg／100mL和65mg／100mL时，泥炭对活性嫩黄K-6G和活性深蓝K—R模拟废水的脱色率分别达到84．6％和86％。其吸附行为符合Langmuir吸附等温式和Freundlich吸附等温式。

Study on the Decolorization of Dyeing Wastewater with Peat

The decolorization of simulated dyeing wastewater on peat adsorbent was studied. The influences of various factors on the deeolorization were investigated. The experimental results indicate that： Peat has a good decolorization capability at a wide pH range. When the dosage of peat are 80 mg/100 mL and 65 mg/100 mL,the deeolorization rate of the reactive yellow K-6G and the reactive blue K-R simulated dyeing wastewater are 84.6% and 86%. The adsorption behaviors of modified attapulgite accord with Langmuir and Freundlich adsorption isothermal equations.
