【摘要】：黄石地区招商引资力度的加大使黄石地区经济飞速发展,同时环境也遭到了恶劣破坏。铝型材建设项目作为黄石地区的支柱产业之一,在生产中会产生大量的含重金属废水、含尘废气和危险固体废物,会污染周围的环境。尤其是铝型材的洗涤废水,在铝型材表面处理过程中的酸蚀、碱蚀、氧化、着色、封孔和钝化等环节后需清洗1~2遍,废水产量多,成分复杂,其中的镍、铬等重金属离子是持久性污染物,进入环境后很难降解,会对环境造成长久的影响。据统计数据,近年来黄石市环境恶化严重,环境承载力减小。黄石市铝型材废水受纳水域——大冶湖和保安湖,已无法满足水域功能保护目标,加强污染源控制管理,改善大冶湖和保安湖的水质,保证水体质量已刻不容缓。因此开展黄石地区铝型材建设项目污染现状分析与评价对实现黄石市铝型材行业健康发展具有重要战略意义。本文主要是在调查黄石市背景环境污染的基础上,通过大量实地调查和专家咨询,对黄石地区铝型材建设项目污染现状进行了系统研究。论文的主要研究工作及结果如下:(1)初步总结了黄石地区铝型材建设项目污染物排放现状,对黄石市环境质量状况进行了全面分析;(2)系统分析了黄石市铝型材建设项目生产工艺流程,并对铝型材生产过程中的污染源进行了探讨,针对废物处理措施,以湖北卓群铝业有限公司为例进行了评价;(3)最后从黄石市环境保护部门和铝型材生产企业的角度提出黄石市铝型材建设项目的污染防治对策。
[Abstract]:The Huangshi region, which has been attracting business and investment, has experienced rapid economic development, and the environment has also been badly damaged. As one of the pillar industries in the Yellowstone area, the aluminum profile construction project will produce a large amount of wastewater containing heavy metals in production. Dust-containing waste gas and hazardous solid waste will pollute the surrounding environment. In particular, waste water from washing aluminum profiles should be cleaned 1 or 2 times after acid corrosion, alkali corrosion, oxidation, coloring, sealing and passivation in the process of surface treatment of aluminum profiles. The waste water has a large output and complex composition. Among them, nickel, chromium and other heavy metal ions are persistent pollutants, which are difficult to degrade after entering the environment, which will cause a long-term impact on the environment. According to statistical data, the environment in Huangshi City has deteriorated seriously in recent years. The environmental carrying capacity of Huangshi aluminum profile wastewater is reduced. The water areas of Daye Lake and Baoan Lake in Huangshi City can no longer meet the targets of water function protection, strengthen the control and management of pollution sources, and improve the water quality of Daye Lake and Baoan Lake. It is urgent to ensure the quality of water body. Therefore, it is of great strategic significance to carry out the pollution analysis and evaluation of the aluminum profile construction project in Huangshi area to realize the healthy development of the aluminum profile industry in Huangshi City. This paper mainly focuses on the investigation of Yellowstone. On the basis of environmental pollution in the city background, Based on a large number of field investigations and expert consultation, the pollution status of aluminum profile construction projects in Huangshi area is systematically studied. The main research work and results are as follows: 1) the pollutant discharge status of aluminum profile construction projects in Huangshi area is preliminarily summarized. This paper makes a comprehensive analysis on the environmental quality situation of Huangshi City, and systematically analyzes the production process of the aluminum profile construction project in Huangshi City, and probes into the pollution sources in the process of aluminum profile production, aiming at the waste treatment measures. Taking Zhuoqun Aluminium Industry Co., Ltd. Hubei as an example, the paper evaluates the pollution prevention and control measures of Huangshi aluminum profile construction project from the point of view of Huangshi environmental protection department and aluminum profile production enterprise.
