摘要
目的 利用地理信息系统通过空间智能分析,结合其他监测,评价垃圾填埋场的二次污染物是否对环境产生污染及其危害。方法 对6个正在使用的生活垃圾填埋场用GPs定位仪进行现场标定。采集6个填埋场的渗滤污水进行实验室检测分析,评价填埋场的二次污染物对环境影响和危害。结果 样品检测显示,污水中含有对人体有害的金属和其他物质,粪大肠菌群3个样品超过最低标准4倍以上。应用GIS技术远期预测填埋场今后长期污染可造成对周围水源的二次污染,并提出相应的策略。结论 6个填埋场如不对二次污染物进行有效处理,对环境、人体健康会产生远期危害效应。
Objective To evaluate the environmental pollution and damage of a secondary contamination from refuse landfill by analysis in combination with field surveillance.Methods The geographical locations of six refuse landfills were measured by global position system (GPS), waste water was collected and tested in laboratory, and the environmental pollution and damage was evaluated by spatial analysis.Results The waste water contained some metal and other substance which were harmful to human body, and the density of stool coliform in thee samples was six times more than that in the minimal standard. The potential and long - term secondary contamination to water sources around landfill was predicted by using GIS analysis, and the relevant strategy to control the secondary contamination was put forward. Conclusion If we don' t dispose a secondary contamination in six refuse landfill, it will produce future damage effect to environment and people health.
