| 摘 要： | 以海南废弃椰壳为原料，采用化学活化法（H3PO4为活化剂）制备椰壳粉末活性炭负载氧化铜催化剂处理酸性大红GR染料废水。研究了椰壳粉末活性炭的制备及负载金属氧化铜的工艺条件，用单因素实验法分别考察了磷酸浓度、液固比、活化温度、活化时间、焙烧温度、焙烧时间以及硝酸铜用量对废水中COD和色度去除率的影响。结果表明：制备椰壳粉末活性炭负载氧化铜催化剂的最优条件为：磷酸浓度65％，液固比3：1，活化温度600℃，活化时间2．5h，硝酸铜溶液（0．5mol·L-1）用量15mL，焙烧温度300℃，焙烧时间2．5h。用此条件下制备的样品处理废水可使COD和色度的去除率分别达到97．48％和99．98％，其相应的出水指标分别为16mg·L-1和5倍数，均达到我国纺织染整工业污染排放标准GB4287--92规定的一级排放标准。
