南方医科大学顺德校区水流分布及水体质量的研究

A Research on Water Distribution and Water Quality of Southern Medical Univirsity's Shunde Campus

以考察顺德校区及其周边水流分布,监测校内水体质量,以便为学校水体系统的完善提供依据为目的;以实地考察的方法研究校内及其周边的水流分布、补给及排导;根据校内水体的分布特点,设计了6个水质监测点,用高锰酸钾法测定水体的COD值,并以此来评价校内水体的质量。结果表明,校内水系为死水,其水量受天气影响较大;易被外水污染;校内水质级别不超过Ⅳ,水质良好。根据"流水不腐"的原理及对国内多所大学的水流系统的研究结果,认为可以引入外围河水,变死水为活水,以改善和维持校内水体质量;建立水质监测兴趣小组,定期对校内水体质量进行监测;修建水坝,使校内水系完全独立于淤滞的水道。

Objective： Investigate the water distribution of Shunde campus and its surroundings, and detect the water quality with the purpose of providing a basis for improving the campus＇ water system. Method： The study of the water distribution, supplement and drainage of the campus and its surroundings is conducted by site investigation. Depending on the water distribution of the campus, six monitoring spots were chosen. The COD values that were used to evaluate the quality of the campus＇ water samples which were taken from the six monitoring spots were gained by the ＂potassium permanganate method＂. Result： The campus to which the north and the south are Shunde tributary and Ronggui waterway while the west and east are fish ponds is located in Magang Island. The whole water of the campus is divided into two dependent systems of which both are dead water. Among the six monitor spots, the water quality measured by the COD value of ABC lives up to degree III while DEF to IV. Conclusion ： It is feasible to introduce peripheral river to run through the campus and turn dead water into running water, so as to improve the campus＇ water quality. The university is suggested to establish an interest group for water quality monitoring to monitor the campus＇ water quality regularly, and build dams so that the water system of the campus is fully independent from the public waterway.
