【摘要】 随着我国社会和经济的高速发展,环境问题日益突出,尤其是水环境的恶化加剧了水资源的短缺。军队环保做为国家环境保护工作的一部分,部队营区污水治理迫在眉睫。本文在查阅有关文献资料的基础上,综述了我国水污染现状及治理情况,分析了部队水污染现状和污染规模、特点,按照生态营区建设的要求,污水未接入市政管网的营区建立独立的小型污水处理站将污水治理后回用。本课题以山东驻军某营区为例,选择适用于营区污水治理及回用的技术方法,进行污水治理工程设计、营区污水治理工程调试及运行管理。山东驻军某营区位于环渤海地区,是国家重点污染治理地区,营区位于市郊,无市政管网,污水未经治理直接通过排污沟排放到营区外无名河。流域内污水排放标准严格,地方政府多次要求其进行治理。营区驻地又是全国重点缺水城市之一,水资源严重短缺,营区污水需治理及回用。根据该营区具体情况,结合营区生态建设要求,将水解酸化一生物接触氧化技术进行改进,采用地埋式污水治理一体综合池设计对其污水进行治理,建成后在地上进行绿化美化。工艺流程简单实用,技术成熟可靠,运行稳定,投资省,操作简便,治理成本低。营区污水治理量约300吨/日,进水化学需氧量约400mg/L,生化需氧量约200mg/L,氨氮约40 mg/L,总氮约50 mg/L,总磷约5 mg/L。经三个月试运行调试后,出水化学需氧量小于50 mg/L,生化需氧量小于10 mg/L,氨氮小于5 mg/L,总氮小于15 mg/L,总磷小于0.5 mg/L,符合《城市污水再生利用景观环境用水水质(GB/T18921-2002)标准要求。营区污水经治理后回用,用于营区浇灌树木花草、补充园内景观用水和洗车,即解决了污水直排污染环境的问题,又可以节约新鲜用水,减少开支,符合生态营区建设要求。更多还原

【Abstract】 With China’s rapid social and economic development, environmental issues become increasingly prominent, especially in the deterioration of water environment exacerbated the shortage of water resources. Military environmental protection as part of the national environmental protection, military barracks, and sewage treatment is imminent.In this paper, on the basis of the relevant literature, reviewed the current situation and control of water pollution, and analyzed the current situation of water pollution and pollution-scale forces, characteristics. In accordance with the requirements of eco-camp construction, not connected to municipal sewage pipe network of the camp should build an independent small sewage treatment station after the sewage treatment reuse. For example, the issue of a military camp in Shandong, selected technology and methods for the camp sewage treatment and reuse, designed of the sewage treatment project; sewage treatment works commissioning and operation management of the camp.Shandong, a camp located in the Bohai region, is a national key pollution control areas. Camp located in the suburbs, there is no municipal pipe network. Sewage is directly emitted into the outside rivers of the camp through the sewage ditch without treatment. The discharge standards of the basin are strict. Local government has repeatedly requested it for treatment. Resident camp is one of the cities of key water shortage. So the camp sewage should control and reuse. Under the specific circumstances of the camp, combined with ecological requirements of the camp, the hydrolytic acidification-biological contact oxidation technology should be improved. Using buried Sewage treatment one integrated tank design as its sewage treatment, and greening the environment. Process is simple and practical, mature and reliable, stable operation, low investment, simple operation, low cost.Sewage treatment camp about 300 t/d, chemical oxygen demand in water of about 400mg/L, biochemical oxygen demand of about 200 mg/L, ammonia about 40 mg/L. total nitrogen of about 50 mg/L, TP of about 5 mg/L. After three months of trial operation after commissioning, the effluent CODcr redused less than 50 mg/L. Biochemical oxygen demand is less than 10 mg/L. Ammonia is less than 5 mg/L. Total nitrogen is less than 15 mg/L. TP is less than 0.5 mg/L. These indicators meet the "urban recycling water for landscape and environmental quality (GB/T18921-2002) standards. Resuse sewage for watering flowers and trees, add water and washing the park landscape, not only solve the sewage straight row of environmental problems, but also save fresh water, reduce costs, meet the ecological requirements of the building barracks.更多还原
