有毒物质在黄河小花河段迁移转化的水质模拟研究

Study of Water Quality Simulation of Poisonous Substances Delivery and Change in the Middle Reaches of the Yellow River

A study of water quality simulation on the delivery,removement and transformation of poisonous substances of para-nitrobenzene-chloride and heavy metal in the natural middle reaches of the Yellow River is made. in the paper,which focused on the influence of sediment of large amount on their movement and destination,determination of water quality model and examination methods. The simulation results are obtained of para-nitrobenzene-chloride and heavy metal and others at the point and large scale input of varied seasons,sediment content,different river siltation and erosion,flow discharge,which is identical to practical measurements in water body.
