Abstract: Laboratory generated chromium (Ⅵ) wastewater treatment was studied by selecting the sludges from fish ponds，pollutant carrying in the recirculation zone of Yangtze River，and landscape pond. Main process conditions for chromium (Ⅵ) wastewater treatment were investigated in making comprehensive utilization of the integrated properties of sludges，such as reduction，adsorption and complexation. Results showed that the sludge from fish ponds was the best；the treatment effect was better with pH value of 3～4 than that with pH of weak acid and neutral. For the selected wastewater with chromium (Ⅵ) concentration of 27 mg/L，15 g/150 mL sludge was sufficient，with which the removal was basically stable higher than 93% after 45 h. This shows that sludge is the convenient efficient and easy material to deal with laboratory Chromium (Ⅵ) wastewater.

摘要： 以实验室产生的Cr（Ⅵ）废水为研究对象，根据其废水的特点，选取鱼塘淤泥、长江回流区纳污淤泥、校园景观池塘淤泥，利用淤泥还原、吸附、络合等综合特性研究其处理Cr（Ⅵ）废水的效果及主要条件。结果表明，鱼塘淤泥是最佳污泥，当pH值为3～4时处理效果强于pH值为弱酸或中性时，对所选废水Cr（Ⅵ）浓度达27 mg/L时，泥水比为15 g/150 mL已经足够；去除率在泥水混合45 h后基本稳定在93%以上。结果表明，淤泥是处理实验室Cr（Ⅵ）废水方便、高效、简便易得的材料。
