摘要
本文以四川大学江安校区景观水体为研究对象,通过近一年,共6次的水质监测采样,研究氨氮、总磷、溶解氧、高锰酸盐指数等水质指标的时空分布特征及变化规律并进行单因子评价。分析了水体富营养化和湖中鱼类的死亡原因并讨论了餐厅排污的影响。研究结果表明:总磷、氨氮和溶解氧是主要污染指标,可导致"水华"、死鱼等问题。最后,提出了相应的治理对策与措施建议。
This article had selected the landscape water body in Sichuan University Jiang＇an campus as the study object and had studied spatial and temporal distribution characteristics and changing rules of ammonia nitrogen, total phosphorus, dissolved oxygen and permanganate index with single factor pollution index method by the water quality monitoring sampling 6 times a year. This article analyzed the cause of water eutrophication and death of fish, and also discussed the influence of pollution discharge of the restaurant. The study results showed that ammonia nitrogen, total phosphorus and dissolved oxygen were the main pollution indicators which leaded to the above-mentioned environmental problems. Finally, some problem-solving measures and suggestions were proposed.
