西安护城河水质模型与控制

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.

Water Quality Modeling and Control of Xi''''an City Circumvallated River

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.
