船舶生活污水处理的实船试验研究

Experimental study on the treatment of ship domestic sewage

采用厌氧复合床反应器与接触氧化、接触沉淀相结合的工艺,设计加工样机处理某货轮生活污水.结合为期3个月的实船试验情况,分析讨论了在船舶这一特殊场所与环境下进行污水处理所遇到的各种问题,重点是水质预处理、水量调节、曝气方式选择,流量输送与控制、供气及自控等附属设备选型与布设,以及布水装置、摇晃与振动影响、装置密封与观察孔布设等细节问题,提出了可能的解决方案,可为船舶生活污水处理装置的进一步开发和完善提供参考.

The combined technology of UBF with contact-oxidation and contact-settling was adopted to design and manufacture a prototype which was installed in a cargo freighter to treat the domestic sewage. Through the 3 months of experiment aboard, some kinds of problems in special surroundings of ship were analyzed and discussed, especially from the aspects such as pretreatment of water quality, regulation of water quantity selection of aeration modes, transportation and control of flux, selection and arrangement of accessory equipments, as well as some details such as water distribution, vibration influence, seal of water and air, and layout of sight holes.Some possible solutions are proposed to solve these problems, and that can offer references to further development and improvement of the treatment plant of ship domestic sewage.
