摘要
根据护城河多排污口的特点,对它进行了分段处理,建立了水质SS及COD的数学模型,并对模型进行求解,选取符合实际情况的参数λ值.利用实测数据对此模型给予验证,结果表明此模型符合实际情况,是可靠的和实用的;并利用假设检验方法对测量数据进行分析,A支的COD水平均高于B支,各点的COD均超过地表水三级标准,两支的SS波动不大.最后对水质的控制提出了五种切实可行的对策.
This paper establishes water quality modeling of circumvallated river using subsection method according to the characteristic of many limber holes.And we get its solution under selecting parameter λ fitting for practice.The model is validated using monitor data.It indicates which is reliable and applied;the analysis of monitor data using hypothesis testing method indicates that COD of the A branch is higher than the B branch,they exceeds the third standard of surface water,SS of both branch waves less.Later,we put forward five feasible countermeasures for control of water quality.
