摘要
表面流人工湿地通常面积较大,难以精细化监测管理,且受进水水量等因素影响,净化功能的退化问题日益显著。以滆湖人工湿地为研究对象,对现状水质、植物及底泥进行分析,在此基础上建立水动力-水质数学模型,并对模型模拟结果进行率定及验证,分析湿地现状水动力-水质特征,模拟不同工况条件下湿地的净化效果。结果表明,模拟结果与实测值拟合良好,现状运行条件下,湿地整体流速较快,连续进水水质净化效果优于间断进水,总进水量适当削减可有效提升水质大部分指标。
Surface flow constructed wetlands generally have a large area and are difficult to finely monitor and manage.Moreover,the degradation of purification function is increasingly significant due to factors such as water inflow.This study focuses on the artificial wetland of Gehu Lake,analyzing the current water quality,plants,and sediment.Based on this,a hydrodynamic water quality mathematical model is established,and the simulation results are calibrated and verified to analyze the hydrodynamic water quality characteristics of the wetland and simulate the purification effect of the wetland under different working conditions.The results show that the simulation results fit well with the measured values.Under the current operating conditions,the overall flow rate of the wetland is relatively fast,and the continuous inflow water purification effect is better than the intermittent inflow.Properly reducing the total inflow can effectively improve most water quality indicators.
