【摘要】：随着我国国民经济的快速发展，贸易往来的增长，水路运输以能耗小、成本低及运输能力大的优势作为当今物流的重要选择，港口作为水陆交接的重要枢纽，其重要性越发突出。然而在港口的建设和运营的同时对区域水环境和水资源带来了诸多污染，保护水环境、治理水污染，是我国实施可持续发展的战略措施。因此，我们必须采取积极有效的措施，，保持港口建设与经济发展相适应、与环境保护相协调。本文介绍了国内外在港口水污染环境保护方面的建设经验，总结了港口的水污染来源、污染防治措施以及污染处理方法。鉴于南昌港樵舍货运码头工程尚属我省政府投资的内河首个危化品码头，在选取该码头作为编制实例的基础上，分析了码头施工和营运期的水污染风险防范与措施，进一步探讨了化学品码头污水处理工艺和水污染防控对策，旨在为建立我省典型示范工程作铺垫，为今后我省港口规划、设计、施工、运营及管理过程提供参考与借鉴。本文的主要研究内容和结论如下： 1、对码头所在陆域和水域的自然资源、社会经济、水环境现状进行了调查与分析，根据码头建设内容、施工安排等，分析码头施工期与营运期水污染的来源和影响，从风险事故、水环境方面提出码头的水污染风险防范与保护措施； 2、通过对工程项目的实例分析，进一步探讨类似散装液体化学品码头的水污染的来源和危害，针对化工废水、生活污水、含油污水三大类污水的处理工艺进行分析，提出化学品码头水污染防控对策。 3、对于化学品码头中处理难度较高的化工废水，采用污水接收罐分类接收化工废水，然后针对不同类型的化工废水分别选择酸碱中和、重力分离、混凝反应、气浮、化学氧化等方法进行预处理，预处理后针对化工废水中有机物含量的不同分别选择SBR、氧化沟、传统活性污泥法和生物接触氧化法等进行生化处理，最后采用砂过滤和活性炭吸附法进行深度处理。
[Abstract]:With the rapid development of our national economy , the growth of trade , the advantages of low energy consumption , low cost and great transport capacity as the important hub of the logistics today , the importance of the port is more and more prominent . However , the construction and operation of the port has brought many pollution to the regional water environment and water resources , and it is a strategic measure to implement sustainable development in our country . Therefore , we must take active and effective measures to keep the port construction adapt to the economic development , and coordinate with the environmental protection . This paper introduces the construction experience of port water pollution environmental protection at home and abroad , summarizes the water pollution source , pollution prevention and control measures and the pollution treatment method of port . In view of the fact that the port engineering of Nanchang Port is the first dangerous goods terminal invested by the provincial government , this paper analyzes the water pollution risk prevention and measures in port construction and operation period , and further discusses the sewage treatment technology of chemical wharf and the prevention and control countermeasure of water pollution . The aim is to pave the way for the establishment of the typical demonstration project of our province , and to provide reference and reference for the future port planning , design , construction , operation and management process of our province . The main research contents and conclusions are as follows : 1 . Investigate and analyze the present situation of natural resources , social economy and water environment in the land area and water area of the wharf , analyze the source and influence of water pollution during the construction period and operation period according to the construction content and construction arrangement of the terminal , and put forward the water pollution risk prevention and protection measures of the terminal from the aspects of risk accident and water environment ; 2 . Through an example analysis of the project , further discuss the source and the harm of water pollution similar to bulk liquid chemical wharf , and analyze the treatment technology of three kinds of sewage , such as chemical wastewater , domestic sewage and oily sewage , and put forward the countermeasures of prevention and control of water pollution of chemical wharf . 3 . Treatment of chemical wastewater with high difficulty in chemical wharf is carried out by using sewage receiving tank to classify and receive chemical wastewater , and then the pretreatment and pre - treatment are carried out for different types of chemical wastewater , such as acid and alkali neutralization , gravity separation , coagulation reaction , air flotation , chemical oxidation and the like , and the biochemical treatment is carried out for different organic matters in chemical wastewater after pretreatment , and finally , sand filtration and activated carbon adsorption method are adopted to perform depth treatment .
