摘要
本文对我国城市河流普遍存在的水质黑臭、严重缺氧的水质转化规律和有机物氧化降解水质模型作了讨论.定义了好氧状态、厌氧状态和亏氧状态的生化降解过程.对亏氧状态有机物降解机制作了详细的分析,论述判断了亏氧状态的几项水质指标.提出由二个方程组成的不同氧收支机制的亏氧状态水质模型组.用鞍山市运粮河连续24～48小时二次现场实测资料,估计模型参数,作了模型验证,经误差分析,结果是满意的.
This paper discusses both the transformation law of rotten and extremely anaerobic water quality,which is popular in China and water quality modelo for degradation of organic matter.The authors give the definition of biochemical degradation process from the aerobic state to the anaerobic state;analyse the degradation mechanism of organic matter in the anaerobic condition,discuss how to establish the standard of anaerobic water quality,and then present several water quality models related to different anaerobic states.Finally,the authors verify a model with the observed data from Anshan Yunling River.Error analysis indicates that the result is satisfactory.
