摘　　要：市政给水管网中重金属污染水源包含铅、镉、汞、铬等重金属元素,受水温、含杂质量以及水流速度影响,使得迁移规律难以监测。为此,提出重金属污染水源迁移规律分析与治理。根据污染物在水中的附着或漂浮状态,采用连续性分析方程计算在不同水温、含氧量、含氮量以及含杂质量水源条件下重金属污染物渗透率和溶解质变化,提出微生物修复和综合性治理技术,实现对水源降解,并通过迁移规律找到污染源头实行根本治理。实验数据证明,所提方法对重金属污染水源迁移规律分析较为清晰,治理后的水源污染情况得到了有效改善。The water sources polluted by heavy metals in municipal water supply network contain lead,cadmium,mercury,chromium and other heavy metals,which are affected by water temperature,impurity content and water flow speed,making the migration rule difficult to monitor.Therefore,the analysis and treatment of heavy metal polluted water source migration rule are put forward.According to the adhesion or floating state of pollutants in water,the continuity analysis equation was used to calculate the permeability and solubility changes of heavy metal pollutants under different water temperature,oxygen content,nitrogen content and water sources with mixed mass.Microbial remediation and comprehensive treatment technology were proposed to achieve water degradation,and the source of pollution was found and implemented fundamental treatment through migration rules.The experimental data show that the proposed method can clearly analyze the migration rule of heavy metal polluted water source,and the water source pollution has been effectively improved after treatment.
