一种基于水动力原理优化的雨污排口水质净化装置

Abstract

本实用新型涉及一种基于水动力原理优化的雨污排口水质净化装置，包括：在雨污排口落水点后中间区域沿水流方向分布多个削减水流流速的石笼，多个石笼布置为至少两排，每排所具有的多个石笼按预定间距依次分布，且沿水流方向每排所具有的石笼的数量依次减少，相邻两排石笼中位于后排的任意一个石笼对着位于前排中其前方相邻两个石笼之间的空隙；石笼包括：笼子以及填充在笼子内的填料层，填料层上种植植物。有益效果为：基于水动力原理对石笼数量、位置进行合理布局，有效实现对雨污排口落水点后中间区域的水流进行阻挡，使雨污排口落水点后中间区域流速减缓且更为均匀，为石笼削减污染物创造条件，促进微生物对污染物的降解，提高水质净化效果。
