前置库技术作为一种生态污水净化处理工艺，可以有效地限制和减少污染物质进入水库。本文提出依据流域年内携污能力最大的第一场洪水量来确定前置库容积的规模，并以洋河水库流域为例，选取2012年洋河水库入库头场洪水过程线作为典型，计算了水库4条主要支流入河口处前置库的容积。结果得出：东洋河、西洋河、迷雾河和麻河的前置库容积分别为169万m3、144万m3、34万m3和29万m3。结果表明采用3年一遇头场雨洪量作为确定洋河水库各支流前置库库容的规模，可较为合理地发挥前置库的作用。
Abstract
As a kind of ecological treatment process for sewage purification，pre -reservoir technology can effectively restrict and reduce
pollutants into reservoir． This paper uses the experience at home and abroad for reference，proposes a determination technique of the scale of
pre-reservoir volume，and Yanghe Ｒeservoir watershed as an example，the flood process line of the first flood for reservoir inflow in 2012 as
a typical example，calculates the pre -reservoir volume of the four tributaries estuary． Ｒesults show that the pre -reservoir volume of
Dongyanghe，Xiyanghe，Miwuhe and Mahe are 169×104 m3
，144×104 m3
，34×104 m3 and 29×104 m3 respectively． The results show that the
actual head rain of once every three years for the principle to determine the scale of the pre-reservoir for each tributary of Yanghe Ｒeservoir
watershed
