干旱地区河流动态水质模型研究

依据干旱地区河流水文、水力特性,合理简化对流扩散方程,给出瞬时突然排污条件下的动态解析解.建立了有干旱地区特点的、含有碳化BOD₅、氨氮和溶解氧三水质要素的河流水质模型,推导出水质模拟矩阵,并应用于新疆乌鲁木齐地区水磨河动态水质模拟计算.

Study on River Dynamic Water Quality Model in Arid Regions

This paper bases on hydrology and hydraulic characteristics to simplify convection disperse functions reasonably and gives a dynamic analytic solutions under instantaneous suddenly draining sewage conditions.This paper also develops a river water quality model with arid region characteristics including three basic water quality factors,carbonized BOD₅,ammoniated nitrogen,and dissolved oxgen,deduces a water quality modeling matrix,and applies it to simulate and estimate the water quality dynamic process in the Shui Mohe River in the arid Urumqi region.
