Abstract Applicability of the solar Fenton process for the treatment of a real refinery wastewater was investigated. A novel solar-reactor was used with the capability of automatic rotating against the sun, enabling maximum utilization of direct and single reflective sunlight beams. The COD and TOC criteria were measured to follow the pollutants removal. Results revealed optimal operating conditions of 694.7 mg/L hydrogen peroxide, 67.3 mg/L ferrous salt and solution pH of 3.2. Under these conditions, COD and TOC were, respectively, decreased to 79.6 and 73.2 % after 180 min sunlight envision. For comparison, alternative H 2 O 2 / F e 2 + , S 2 O 8 2 - / F e 2 + , N a O C l / F e 2 + , N a O C l , S 2 O 8 2 - and H 2 O 2 processes, all activated with sunlight, were performed. The present pollutants were identified by means of the GC/MS headspace technique, showing significant removal of the majority of petroleum aliphatic and aromatic hydrocarbons and that biodegradability was feasible since BOD5/COD reached from 0.36 to 0.62. The process performance was compared with the previously reported similar processes for treating specified pollutants and wastewaters. High preference of the employed process using the particular solar-reactor was probed based on different criteria. Meanwhile, the total operating costs was estimated to be quite low, compared to other processes.

用于处理炼油厂废水的中试旋转反应器中的均相太阳能芬顿和替代工艺

摘要 研究了太阳能 Fenton 工艺在处理实际炼油厂废水中的适用性。使用了一种新型太阳能反应器，具有逆着太阳自动旋转的能力，能够最大程度地利用直射和单反射阳光光束。测量 COD 和 TOC 标准以跟踪污染物的去除情况。结果显示最佳操作条件为 694.7 mg/L 过氧化氢、67.3 mg/L 亚铁盐和 3.2 溶液 pH 值。在这些条件下，在阳光照射 180 分钟后，COD 和 TOC 分别降低至 79.6% 和 73.2%。为了比较，替代 H 2 O 2 / F e 2 + 、S 2 O 8 2 - / F e 2 + 、N a OC l / F e 2 + 、N a OC l 、S 2 O 8 2 - 和 H 2进行所有用阳光激活的O 2 过程。目前的污染物是通过 GC/MS 顶空技术鉴定的，显示出大部分石油脂肪族和芳香烃的显着去除，并且生物降解性是可行的，因为 BOD5/COD 达到了 0.36 到 0.62。该工艺性能与之前报道的处理特定污染物和废水的类似工艺进行了比较。基于不同的标准探讨了对使用特定太阳能反应器的所采用过程的高度偏好。同时，与其他工艺相比，估计总运营成本相当低。该工艺性能与之前报道的处理特定污染物和废水的类似工艺进行了比较。基于不同的标准探讨了对使用特定太阳能反应器的所采用过程的高度偏好。同时，与其他工艺相比，估计总运营成本相当低。该工艺性能与之前报道的处理特定污染物和废水的类似工艺进行了比较。基于不同的标准探讨了对使用特定太阳能反应器的所采用过程的高度偏好。同时，与其他工艺相比，估计总运营成本相当低。
