- 1 - 曲阜护城河水质研究评价08 级环境科学高钊指导老师唐美珍【摘要】 由于人为的不合理利用，以及生活污水、 工业废水的无限制排放，必然引起护城河河水的污染。 护城河位于市中心，而且曲阜市是著名的旅游胜地，河水的水质对于曲阜的发展有十分重要的意义。所以，采集不同地点护城河水, 对河水中总磷、总氮、溶氧、COD、氨氮进行测定，来对护城河的水质进行评估。结果表明，护城河的河水中P、N元素严重超标，富营养化程度较严重，整体水质严重污染，营养状态及水质状态处于相对较高的风险状况之中。最后针对上述情况提出护城河水环境改善措施和建议，以期其充分发挥其景观水体得综合效益。关键词 ：水质总磷总氮化学需氧量Study on the water quality evaluation of Qufu MoatStudent majoring in Environmental Science Gao Zhao Tutor Tang Mei zhen Abstract： Due to unreasonable use, as well as domestic sewage, industrial wastewater without limiting emissions, it will cause the moat river pollution. The city of Qufu is a famous tourist resort, and the moat is located in the downtown area, the river water quality has very important significance to the development of Qufu .As a result ,to collect the water of Qufu Moat in different places, and to evaluate water quality of the moat through the measurement of the total phosphorus Total nitrogen and total carbon of the water. The results show that, the elements of phosphorus nitrogen and carbon in the moat water severely exceed the standard. The degree of eutrophication is becoming more and more serious now, in a world , the overall water -quality is too poor to be improved. Finally, I suggest some measures in order to improv ing it’ s water-quality.
