新建花溪大学城对思雅河水质的影响研究

Influence of Huaxi College Town on water quality of Siya River

为了解新建花溪大学城对地表水水质的影响,在思雅河大学城段布置10个采样点,对各采样点不同季节水质进行分析,监测pH、温度、悬浮物、COD、氨氮、总磷和细菌总数等指标。研究结果表明:思雅河流经大学城前后水质由Ⅲ类变为劣Ⅴ类,从大学城河段上游到下游,除pH外的各指标均有逐渐上升的趋势。高校和周边居民生活污水的排放以及临河村落居民生活垃圾的随意丢弃是导致水质恶化的主要原因。

In order to understand the impact of the newly built Huaxi College Town on the surface water quality,ten sampling points were settled along the college town section of Siya River to analyze the variation of water quality in different seasons.Temperature,pH value,suspended solid,COD,ammonia nitrogen,total phosphorus and total number of bacteria were chosen as indexes of water quality.The results showed that the water quality of Siya River changed from Class III to Class V after the river flowed through the college town.All indicators except pH value increased gradually from the upper reach to the lower reach of the college town section of the river.The discharge of domestic sewage from colleges and residents,and the disposal of domestic garbage from surrounding villages were the main causes of water quality deterioration.
