| 摘要: |
| 为探究可以实现压载水达标排放的处理手段，建立了可以控制实现O3、UV单独处理的O3/UV复合压载水处理中试系统.以大肠杆菌和杜氏盐藻为目标微生物，MPN法计数剩余活菌数，CFDA-AM荧光染色法计数剩余活藻数，对该中试系统灭活微生物性能进行研究；N, N-二乙基对苯二胺(DPD)分光光度法测定该系统产生的总剩余氧化物(total residual oxidants, TRO)的衰减.结果表明，O3和UV具有协同作用，二者复合要优于单独处理的灭活效果.辐照度67 μW/cm2、O3投加量1.62 g/h、处理1.0 s、出水2 h后即检测不到大肠杆菌和杜氏盐藻的存在，能够满足国际海事组织关于微生物灭活标准.TRO浓度会随着时间的延长而衰减，且实验并未检测到菌和藻的复活，说明该系统具有理想的持续灭活性能.O3/UV复合压载水处理系统弥补了单一处理手段效率低的缺点，二者复合有利于降低能耗，可望成为新一代处理手段.

| Abstract: |
| To explore the treatment method that enables the quality of ballast water to meet the discharge standard, the O3/UV combined ballast water treatment system was established, in which O3 and UV can be controlled independently. Escherichia coli and Dunaliellasalina are target microorganisms. To study the system performance in inactivating microorganisms, MPN and CFDA-AM fluorescence staining were used to count residual viable bacteria and residual viable algae respectively. N, N-Diethyl-p-phenylenediamine (DPD) spectrophotometry was used to measure the attenuation of total residual oxide (TRO) generated in the system. The results show that O3 and UV have a synergistic effect, and the combination of the two has better performance of inactivation than that of the individual treatment. Under the condition of 67 μW/cm2 UV irradiance, 1.62 g/h of the O3 dosage for 1s exposure, the Escherichia coli and Dunaliellasalinacan cannot be detected after 2 h, which means the effluent can meet IMO microbial inactivation standards. TRO concentration decayed with time, and the experiment did not detect the resurrection of bacteria and algae, which indicate a good continuous inactivation performance of the system. Compared with individual treatment, the combined system increases the treatment efficiency and reduces the energy consumption, which makes itself a promising method.
