摘要
为了保障城镇居民的用水安全,提出工业废水排放对河流水体质量影响研究。基于有机物反应焓变计算有机物对水体质量影响的单位熵增,通过生化/化学反应计算氮磷对水体质量影响的单位熵增,以计算熵增数据为依据,构建河流水体质量动态变化模型,计算工业废水对水质的影响系数,即可确定工业废水排放对河流水体质量的影响程度。实验成果显示应用方法提出后,获得的工业废水排放对河流水体质量的影响程度与实际影响程度一致,充分证实了提出方法应用性能较佳。
In order to ensure the water safety of urban residents,the impact of industrial wastewater discharge on river water quality is proposed.The unit entropy increase of the impact of organic matter on water quality is calculated based on the enthalpy change of organic matter reaction,and the unit entropy increase of the impact of nitrogen and phosphorus on water quality is calculated through biochemical/chemical reaction.Based on the calculated entropy increase data,the dynamic change model of river water quality is constructed,and the impact coefficient of industrial wastewater on water quality is calculated to determine the impact degree of industrial wastewater discharge on river water quality.The experimental results show that after the application of the proposed method,the impact of industrial wastewater discharge on river water quality is consistent with the actual impact,which fully proves that the application performance of the proposed method is better.
