哈尔滨市磨盘山水库供水工程环境与卫生学评价

Environmental Impact Assessment of Water Supply Project of Mopan Mountain Reservoir in Harbin

目的对哈尔滨市磨盘山水库供水工程进行环境与卫生学评价。方法收集哈尔滨市磨盘山水库所在辖区五常市的人口学、医疗卫生资源、人群健康、传染病疫情、气象、农药、化肥资料,并于2002年对磨盘山水库库区及周围区域进行流行病学、病媒动物及昆虫、环境质量、水质等方面的现场调查与监测。结果磨盘山水库开发区各种主要传染病均处于较低发病水平,近10年该地区未发生重大传染病疫情和突发公共卫生事件。在磨盘山水库汇水区域内未发现排放有毒化学物质的厂矿企业;农药、林药、化肥监测结果均低于GB3838—2002《地表水环境质量标准》中规定的限值。水质监测结果显示,水库水中各项指标均符合《生活饮用水卫生规范》(2001)的要求。结论磨盘山水库建设工程引起已知传染病传播的危险性极小。磨盘山水库水质符合《生活饮用水卫生规范》(2001)的要求,在全面实施《磨盘山水库供水工程库区卫生清理工作方案》及实施细则后,磨盘山水库可以作为哈尔滨市居民生活饮用水水源。在控制环境潜在性污染因素后,不会对周围生态产生明显影响。

Objective To do the environmental impact assessment for the water supply project of Mopan Mountain Reservoir in Harbin. Methods To collect the related data and to do the field-investigation and inspection in epidemiology, animals and insects, environmental quality sanitization and water quality, etc in the area of Mopan Mountain Reservoir and the surroundings. Results The main infectious disease in the development area of Mopan Mountain Reservoir was at the lower prevalence level and there was no fatal infectious disease such as plague , cholera in the recent ten years. Besides, there was no grievous public health emergency. There were no factories and collieries emitted poisonous chemical material in the catchment area. The results of water quality investigation showed that all the indexes were up to the related standards. Conclusion Monpan Mountain Reservoir project is not ease to cause the infectious diseases spread by water among the people. The water quality can meet the request for water source. The reservoir will not influence the ecological environment when the latent environment pollution factors are under control.
