| 摘 要： | 研究了载重量5t的黄磷运输汽车发生黄磷泄漏对香溪河流域的环境影响。泄漏的黄磷及污水与香溪河水混合后的总磷预测值:按河水多年平均流量(47.4m3/s)为0.3087mg/L,总磷浓度超标1.5倍;按洪水期最大流量(2890m3/s)为0.1526mg/L,不会对受纳水体造成明显污染;按枯水期最小流量(14m3/s)为0.6868mg/L,总磷浓度超标3.4倍。当发生黄磷燃爆引发P2O5大气污染事故时,半致死浓度范围为以事故点为圆心,半径约为60m的圆形区域;主要污染影响范围为事故源下风向3900m范围内。上述污染影响范围的确定,为事故的应急处理提供了科学依据。

| Abstract: | The environmental impact of yellow phosphorus leakage on Xiangxi River valley with the vehicle of loading capacity of 5 tons was analyzed.Leaked yellow phosphorus and sewage mixed with water of the River contributed to the predictive value of total phosphorus of 0.3087mg/L according to average flow of the River 47.4m3/s,which exceeded the standard 1.5 times,while 0.1526mg/L by largest flood flow of 2,890m3/s,which would not cause obvious pollution to the receiving water,and 0.6868mg/L according to the minim... |
