以灵芝为菌种，在间歇式反应器中对印染废水进行处理。对印染废水的水质进行了研究。研究了pH值、温度、搅拌速度和染料废水浓度等工艺参数对染料脱色和降解的影响。利用响应面方法(RSM)对这些参数进行了优化。结果表明，在pH值为6.6、温度为26.5℃、搅拌速度为200转/分、染料废水浓度为1：2的条件下，染料废水的脱色率和COD降解率分别达到81.4%和90.3%。动力学研究采用一阶模型、扩散模型和Singh模型。结果表明，降解遵循一级反应模型。
In this work, treatment of textile dye wastewater was carried in a batch reactor using Ganoderma lucidum. The characteristics of textile dye wastewater were studied. The effect of process parameters like pH, temperature, agitation speed and dye wastewater concentration on dye decolourization and degradation were studied. These parameters were optimized using response surface methodology (RSM). From the results, the optimized conditions were: pH 6.6, temperature 26.5 °C, agitation speed 200 rpm and dye wastewater concentration 1:2. At these optimized conditions, the maximum decolourization and COD reduction were found to be 81.4 and 90.3 %. Kinetic studies were carried out using different models like first-order, diffusional and Singh model. From the results, it was found that the degradation follows the first-order reaction model.
