摘要
随着城镇污水处理厂运行年限不断增加,老旧污水处理厂中各工艺单元的污水渗漏问题日益突出.在考虑实际水文地质条件及确定污染源强的基础上,对研究区域建立三维数值模型,使用GMS对污水处理厂发生连续性渗漏可能导致的地下水污染进行数值模拟预测.结果表明,老旧厂区高污染工艺段如果长期发生连续性渗漏,可能会对厂区周边地下水体造成一定影响,应定期对老旧污水厂水处理构筑物进行防渗防腐处理,加强对污水渗漏点的监测与修复,减少地下水污染风险.
Abstract
With the operating years of urban sewage treatment plants,the issue of sewage leakage in each process unit of old sewage treatment plants is becoming increasingly prominent.On the basis of considering the actual hydrogeological conditions and determining the strength of pollution sources,a three-dimensional numerical model was established for the study area to simulate and predict the groundwater pollution that may occur due to continuous leakage in the sewage treatment plant using GMS.The results indicated that if continuous leakage occurred in the high pollution process section of the old treatment plant area for a long time,it might have a certain impact on the surrounding groundwater bodies.Regular anti-seepage and anti-corrosion treatment should be carried out on the water treatment structures of the old sewage treatment plant,and monitoring and repairing of sewage leakage points should be strengthened to reduce the risk of groundwater pollution.
