【摘要】：目的 :了解某部营区池塘水富营养化程度及其对环境的影响 ,为提高部队环境生活质量提供依据。方法 :对某部营区 6处池塘水进行调查 ,选择总磷 (TP)、总氮 (TN)、耗氧量(CODMn)、叶绿素a(chla)为评价指标 ,按水质分析方法国家标准汇编及湖泊富营养化评价与分级标准进行检验和评价。结果 :6处池塘水的总磷、总氮含量较高 ,其均值分别为 (0 .132± 0 .0 78)mg·L 1和 (1.0 84± 0 .5 85 )mg·L 1。使水体的自净能力降低 ,藻类繁殖 ,出现散在蓝藻 ,同时 ,水体透明度下降 ,溶解氧降低 ,导致水体臭味增大 ,水质恶化 ,处于中富营养状态 ,且有向重富营养发展的趋势。结论 :该部 6处池塘水都处于中富营养状态 ,其原因与部队生活污水中的含磷洗涤剂和农副业生产中使用含磷杀虫剂造成的持续污染和营区排污管的布设不合理 ,使污水倒灌有关。因此 ,应搞好营区环境综合治理 ,势在必行
[Abstract]:Objective: to understand the eutrophication degree of pond water and its influence on environment in a camp area, and to provide basis for improving the quality of life of troops. Methods: the total phosphorus (TP),) total nitrogen (TN),) oxygen consumption of (CODMn), chlorophyll a (chla) was selected as the evaluation index. According to the national standard compilation of water quality analysis method and lake eutrophication evaluation and classification standard, the test and evaluation are carried out. Results the contents of total phosphorus and total nitrogen in water of pond at 6: 6 were higher (0.132 卤0.078) mg L 1 and 1.084 卤0.585) mg L 1, respectively). At the same time, the transparency of the water decreased and dissolved oxygen decreased, which led to the increase of the odor, the deterioration of water quality, and the status of medium and eutrophication, which resulted in the decrease of the self-purification ability of the water body, the propagation of algae and the appearance of cyanobacteria scattered in the water. And there is a trend to the development of eutrophication. Conclusion: all of the 6 ponds in this department are in the status of medium and eutrophication, which is due to the continuous pollution caused by phosphorus containing detergents in the domestic sewage of the army and the use of phosphorous insecticides in the production of agricultural sideline, and the unreasonable layout of sewage pipes in the camp areas. Relating to the pouring of sewage. Therefore, it is imperative to do a good job of comprehensive environmental management in the camp area.
