污泥焚烧渣处理含镍废水的模拟实验

Simulated experiment of treating nickel-containing wastewater with sludge incineration residue

污泥焚烧渣具有较大的表面积，对镍离子有一定的吸附能力。本文研究了吸附时间、镍离子初始浓度、废水pH和城市污泥焚烧渣投加量对废水中镍离子吸附率的影响。结果表明，当镍离子初始质量浓度为30mg／L，废水pH为7．0，吸附时间为6h，城市污泥焚烧渣投加量为10gm时，吸附效果最佳。

Sludge incineration residue has the features of large surface area and certain adsorption property with Ni2＋. The effects of adsorption time, initial concentration of Ni2＋, pH and the addition amount of sludge incineration residue on Ni2＋ adsorption rate in wastewater were studied. The results showed that the adsorption property is the best under the conditions of initial mass concentration of Ni2＋ 30 mg/L, pH 7.0, adsorption time 6 h and sludge incineration residue 10 g/L.
