摘要
对石家庄市污染源进行调查，在调查的项目中，化学需氧量是主要污染源，其次为氨氮。通过对石家庄市不同行业污水排放量调查，污水排放量最大的行业为化工行业；对污水排放去向分析，84．32％的污水流人汶河；石家庄市污水对地下水的污染途径主要为厂区污染、排放过程中的污染和污水灌溉污染。选择常规类离子、氮类化合物、有毒物质类项目的监测结果，与1999年监测结果进行对比分析，大部分污染物含量有所增加。以1985年对污染物监测结果作为背景值，分别对评价区进行评价，划分为未污染区、轻污染区和中等污染区。未污染区占评价面积的62．5％，轻污染区占38．5％，中等污染区占1．7％。最后提出地下水保护的措施和建议。
Based on the investigation of pollution sources in Shijiazhuang, chemical oxygen demand is the main source of pollution and ammonia is the next. Through the survey of sewage quantity about different industries in Shijiazhuang, chemical industry ranks first; 84. 32% of the sewage inflow to the Xiaohe river after analyzing the discharge direction of sewage. Sewage pollutes the groundwater mainly through the following ways： the factory pollution, the discharging process pollution and sewage irrigation pollution. Choosing the monitoring results on conventional ion, nitrogen compounds and toxic substances, we find most pollutants content increasing compared with the results of 1999. Evaluating the eval- uation areas,we divide them into non pollution, light pollution and secondary pollution zone based on the pollutant monitoring results in1985. Non polluted area accounts for 62. 5% of the area,light pollution 38. 5%, moderately polluted area 1.7%. Finally, we list the suggestions and measures on groundwater protection.
