摘要
本文对粉煤灰沸石处理芬顿试剂氧化后的柠檬酸废水进行工艺条件试验,考察了温度、粉煤灰沸石投加量、吸附时间对处理效果的影响,并对芬顿试剂单独处理和与粉煤灰沸石协同处理的效果进行了对比。结果表明,在温度为20℃、粉煤灰沸石质量浓度为3g/l、吸附30min时,废水中的CODcr去除率达到97.26%,在处理的效率和稳定性方面,均优于芬顿试剂单独处理。
In this paper, it conducts the fly ash handles zeolite Fentoffs reagent citric acid oxidation of process wastewater technological experiments. It inspected the temperature, fly ash dosage zeolite adsorption time on the effect of treatment, and Fentoffs reagent alone with the fly ash handling and processing of zeolite with the effect of contrast. The results showed that the removal rate of wastewater CODcr reached 97.26%, in the conditions of 20 ℃, the quality of fly ash zeolite concentration of 3 g/1 and 30 min of adsorption. It was better than Fentoffs reagent dealing separately, in the dealing with efficiency and stability.
