目前，船舶污水处理采用油污水和生活污水2套装置，设备多，运行管理工作量大。而一体式污水处理系统却能实现两者有机结合，将高浓度的油污水经预处理后与生活污水一同混合处理，弥补上述不足。实验采用以陶粒曝气生物滤池为主体的处理装置，处理模拟船舶污水（油污水经过预处理），当进水化学需氧量COD=720.21 mg/L，油份浓度C油=65.87 mg/L，曝气量Q=0.4 L/min，温度T=30℃，pH=8.5，水力停留时间HRT=90 min，出水COD=44.00 mg/L，C油=6.56 mg/L，两者去除率分别为93.89%和90.04%，对油份的耐受浓度约为76.35 mg/L。并在实验基础上，构建了一体式污水处理系统，为船舶污水处理系统的改进、开发提供借鉴和参考。
At present, the ship sewage was treated by domestic sewage treatment equipment and oily sewage treatment equipment. The number of equipments was large, so was the workload of operation and management. The integrated sewage treatment system combining of the two devices could make up for the deficiencies above. High concentration ship oily sewage was pretreated, then the pretreated oil sewage mixed with domestic sewage was treated together in the integrated sewage treatment system. A ceramiste biological aerated filter (CBAF) as the main treatment unit was constructed to treat simulated ship sewage. Under the condition:Q=0.4 L/min,T=30℃,pH=8.5,HRT=90 min, when the influent concentration for COD and oil were 720.21 mg/L and 65.87 mg/L, the effluent concentration for COD and oil was 44.00 mg/L and 6.56 mg/L, with the removal rate 93.89% and 90.04% respectively. The maximum concentration of oil that CBAF could withstand was 76.35 mg/L. On the basis of these experiments, an integrated sewage treatment system was constructed, which could provide reference for the improvement and development of ship sewage treatment system.
