摘要/Abstract

摘要： 为保障饮用水源地闹德海水库的水质安全,通过选取不同氮磷允许负荷量的测算模式进行综合分析。结果表明:闹德海水库实际负荷量总氮为139.98 t/a、总磷为28.28 t/a,目前已处于中—富营养化状态;水库若要达到贫—中营养化状态,应削减总氮129.96 t/a,总磷27.27 t/a。为此,从发展农业节水、综合防治化肥、农药、畜禽养殖业污染及治理水土流失等方面提出了科学的污染防治思路及削减对策。

Abstract: In order to ensure the water quality security of drinking water source in Naodehai reservoir,the allowable loads of nitrogen and phosphorus in different modes were analyzed.The results indicated that the actual loads of the total nitrogen and the total phosphorus in Naodehai reservoir were 139.98 t/a and 28.28 t/a,respectively.At present,the total nitrogen contents and the total phosphorus contents should be cut 129.96 t/a and 27.27 t/a respectively,in order to achieve the poor or middle eutrophication grades from the middle or abundant one.Therefore,the scientific ideas and load reduction countermeasures were presented in terms of the conservation of agricultural water consumption,pollutions controlling from fertilizer,pesticide,livestock and soil erosion controlling.
