摘要:
针对某化工厂冷却剂生产过程中所产生的四氯化碳废水(四氯化碳质量浓度为495.46 ?滋g/L),采用了萃取和高效污染质分离器的一体化工艺进行实验研究,确定了高效污染质分离器包括厌氧处理和好氧处理,探讨了降解时间、温度、初始pH、葡萄糖浓度等因素对厌氧阶段和好氧阶段的影响. 结果表明:在四氯化碳废水/厌氧污泥水为1∶2,厌氧降解时间为5 d,反应温度为33 ℃,反应初始pH为7.0,葡萄糖质量浓度为20 g/L的条件下,厌氧处理效果最好,四氯化碳降解率达80.1%. 在厌氧污泥出水/好氧污泥水为6∶15,好氧的降解时间为2 d,反应温度为30 ℃,反应初始pH为4.5、葡萄糖浓度为15 g/L的条件下,好氧处理效果最好,四氯化碳的降解率为42.4%. 经过上述处理,四氯化碳的质量浓度为0.346 ?滋g/L,可达到《污水综合排放标准》(GB8978-1996)一级标准0.03 mg/L的要求.
Abstract:
To explore a new way of treating wastewater containing carbon tetrachloride, the wastewater produced during the production process of coolant was used to study. The integrated process including extraction and efficient pollutant separator was adopted, and the efficient pollutant separator includes anaerobic treatment and aerobic treatment. Different factors, such as time, temperature, pH and so on, were probed in anaerobic treatment and aerobic treatment. The results show that anaerobic treatment works best as degradation rate of carbon tetrachloride is 80.1% at degradation time of 5 d, temperature is 33 ℃, initial pH of 7.0 and the concentration of glucose of 20 g/L. And aerobic treatment works best as degradation rate of carbon tetrachloride is 42.4% when the ratio of anaerobic sludge water and aerobic sludge water of 6∶15, degradation time of 2 d, temperature of 30 ℃, initial pH of 4.5 and the concentration of glucose of 15 g/L. After that, the concentration of carbon tetrachloride is 0.346 ?滋g/L.
