回灌条件下地下水质模拟与预测

The Quality Simulating and forecasting of Groundwater under Recharge Conditions

本文建立人工回灌条件下地下水质模型系统 ,模拟了 7种污染因子的时空运移规律。在模拟中对水质模型的求解首次采用分步杂交方法 ,取得了满意效果。通过模型运转的预测结果 ,对模拟因子其浓度与回灌量、水量参数、水质参数、回灌时间和回灌距离的相互关系进行了分析 ,最终为确定“回灌水临界水质标准”提供依据。

The water quality model system of artificial recharge of groundwater is established herein and the temporal and spatial transport laws of seven kinds of pollutants are simulated.In order to solve the model the step hybrid calculating method is firstly used and the satisfactory results are obtained.Through the forecasted results from operating the model the relationship of pollutants' concentrations with recharge quantity,periods,distances between recharge well and observed well and related parametes are analyzed to provide the basis for determining critical water quality standard of recharge water.
