【摘要】：随着国务院振兴东北老工业基地计划的实施,吉林省的城镇化进程不断加快,工业化程度不断提高,相继而来的是吉林省的水资源短缺、水质恶化、生态环境脆弱等问题的日益严重,水资源供需矛盾日益突出。吉林是农业大省,农业基础地位牢固,地下水在农田灌溉起着非常重要的作用。因此地下水资源在吉林省的经济社会发展中起着不可替代的作用。在吉林省开展地下水基础环境状况研究评估,掌握吉林省地下水水质状况,为科学地制定地下水环境保护措施、切实保障地下水环境安全提供信息数据支撑,实现地下水资源的可持续利用具有十分重要的作用。本文以德惠市第三地下水水源地为调查对象,以兼顾“双源”的原则,通过调查案例地区自然地理和社会经济情况、区域水文地质以及案例地区工业、生活和农业生产等污染源分布基本情况,对地表水和地下水水质状况进行调查研究并进行评价。从研究区域地下水饮用水源地和周边污染源的基本属性、管理状况、水质状况、敏感点(风险源)以及各类污染源对研究区域水源地地下水水质的影响等方面,系统分析案例地区地下水水质状况,综合评价了地下水污染程度。对地表水环境和地下水的监测及水质状况的评估都严格按照国家相关标准和规定进行,通过大量的实地工作,采集了德惠市第三水源地区域各类污染源分布、排放污染物数量以及反映地表水和地下水水质状况的大量基础性数据。根据调查数据对案例地区地下水水质状况进行了综合的研究和评价,针对地下水中铁、锰、氨氮、亚硝酸盐氮和总大肠菌群的超标情况以及阴离子合成洗涤剂等污染的问题,提出了相关的保护性建议和对策。
[Abstract]:With the implementation of the plan of the State Council to revitalize the old industrial base in Northeast China, the process of urbanization in Jilin Province has been speeding up and the degree of industrialization has been continuously improved. In succession, the water resources in Jilin Province are short and the water quality is deteriorating. The problem of fragile ecological environment is becoming more and more serious, and the contradiction between supply and demand of water resources is becoming more and more prominent. Jilin is a big agricultural province, the agricultural foundation is solid, groundwater plays a very important role in farmland irrigation. Therefore, groundwater resources play an irreplaceable role in the economic and social development of Jilin Province. To carry out the research and evaluation of groundwater basic environment in Jilin Province, to grasp the groundwater quality in Jilin Province, to provide information and data support for the scientific formulation of groundwater environmental protection measures and to ensure the groundwater environmental safety. It is very important to realize the sustainable utilization of groundwater resources. In this paper, the third groundwater source of Dehui City is taken as the object of investigation, and the principle of "double sources" is taken into account. Through the investigation of the natural geography and social economic situation, regional hydrogeology and case study of regional industry, The distribution of pollution sources, such as living and agricultural production, was investigated and evaluated. In this paper, the basic attributes, management status, water quality status, sensitive points (risk sources) and the effects of various pollution sources on the groundwater quality of the regional groundwater sources are studied. The groundwater quality in the area is analyzed systematically and the groundwater pollution degree is evaluated synthetically. The monitoring of surface water environment and groundwater and the assessment of water quality are carried out in strict accordance with the relevant national standards and regulations. Through a lot of field work, the distribution of various pollution sources in the area of the third water source in Dehui City has been collected. The amount of pollutants discharged and a large number of basic data reflecting the water quality of surface water and groundwater. Based on the investigation data, a comprehensive study and evaluation of the groundwater quality in the case area was carried out. The pollution of iron, manganese, ammonia nitrogen, nitrite nitrogen and total coliform bacteria in groundwater and the contamination of anionic synthetic detergents were analyzed. The protective suggestions and countermeasures are put forward.
