摘要
指出了水体富营养化是当今世界面临的主要的水污染问题之一。以RL矿区塌陷塘为例进行了富营养化研究,以CK塌陷塘为对照塘。测定了其pH值、EC、TDS、DO、氨氮、CODMn、TN、TP、叶绿素a和SD,运用综合营养指数法(TLI)对该塌陷塘的富营养化情况进行了评价。结果表明:RL矿区塌陷塘pH值在6~9之间,符合标准。溶解氧都大于5mg/L,达到Ⅲ类水标准。化学需氧量都小于15mg/L,达到Ⅰ类水标准。氨氮小于0.5mg/L,达到Ⅱ类水标准。总磷小于0.05mg/L,达到Ⅲ类水标准。总氮都小于1mg/L,达到Ⅲ类水标准。总体来讲,该塌陷塘为Ⅲ类水。RL矿区塌陷塘基本没有达到富营养化水平。大部分处于中营养水平,只有少数处于轻度富营养化水平。CK塘处于中营养水平。
Eutrophication is a major water pollution problem in the world today. This paper studies eutrophication of RL mine subsidence pond. CK pond is used as a comparison, pH, EC, TDS, DO, ammonia, CODMn, TN, TP, chlorophyll a and SD are determined. In this paper, eutrophication of the collapse pond was evaluated by comprehensive nutrition index （TLI）. The results show： pH of RL mine subsidence pond is between 6-9. Dissolved oxygen is less than 5 mg/ L, reaching III water standard. COD is less than 15mg / L, reaching I water standards. Ammonia is less than 0.5mg / L, reaching II water standards. Total phosphorus less than 0.05mg / L, reaching II water standard. TN less than ling / L, reaching III water standards. Overall, the collapse pond reaches III water pond. RL mine subsidence pond basically did not reach the level of eutrophication. Most are at medium nutritional levels, and only a few are at a slight eutrophication. CK Tong is at a medium nutrient level.
