摘要

本文是关于南京油港罐区污水处理工艺的设计，其主要是对罐区污水处理的流程、效果、经济性进行改进与完善，并就一些原有设施进行检修与重建，保证工艺能够不间断、不受突发情况影响的进行污水的正常处理。在目前，随着港区的投入使用与发展的不断加深，原有工艺流程因为日益严重的问题已经不再适用于日常工作的使用，其问题包括：土地面积占用大，过度依赖人工处理，自动化程度低，运行时系统不稳定，运行操作时费用较高，且没有进行有效的清污分流工作，含油污水处理量较大，降低了对乳化油、COD以及NH3-N的去除率，导致经处理后，出水中的石油类以及其他污水中的SS、COD等含量依然很高等等。所以本次设计在原有的基础上，检修并改进了流程中原有的设备，并在处理工艺之前加入了清污分流技术，以减少污水的总量，减轻设备的压力，能够更为有效的进行工作。同时应对涡凹气浮技术无法单独有效的去除COD等杂质的问题，在涡凹气浮池之后增加了曝气生物滤池工艺，使后续流程改进为CAF与BAF的组合工艺，这样可以进行优势的互补，最大化清除油污中的杂质。在布置总体布局时，由于BAF池的加入，罐区原有布置不利于流程的运行，故将CAF池进行了重建，减少多余的管道，保证了新的工艺流程能够满足日常排放的标准。经过初步的经济可行性论证，预计在投入使用后能够得到更好的净化效果。

Abstract

This article is about the Nanjing Port tank sewage treatment process design, which is mainly the tank sewage treatment process, effect and economic improvement and perfection, and some of the original facilities for maintenance and reconstruction, to ensure that the process can not be interrupted, emergency water normal processing. In the current, with port put into use is associated with the development of deepening, the original process because of the increasingly serious problem is no longer applicable to the use of daily work. The problems include: land area occupied by large, excessive dependence on manual processing, low degree of automation, operation system instability, operation cost is higher and there is no effective decontamination triage work, oily sewage processing capacity greatly, reduces the emulsified oil, COD and NH3-N removal rate, resulting in after treatment, the effluent oil and other sewage in SS and COD content is still very high and so on. So the design on the basis of the original, maintenance and improvement of the process in the original equipment, and in the process before joining the decontamination triage technology, to the total amount of effluent reduction, reduce pressure, to more effectively carry out the work. Also deal with cavitation air flotation technology alone can not effectively remove COD and other impurities, in the wake of the cavitation air flotation pool increased biological aerated filter process, so that the follow-up process improved the combination process of CAF and BAF, so can the advantages of complementary, the maximum scavenging impurities in the oil. In the overall layout of the layout, due to addition of BAF pool, original tank layout is not conducive to the flow of operation. Therefore, the caf pool were reconstructed, reduce redundant pipes, to ensure that the new process can meet the daily emission standard. After a preliminary economic feasibility study is expected to be put into use after being able to get a better purification effect.
