摘要： It is an object of the present invention to provide a filtration system capable of achieving both uniform backwashing of floating filter media layer and efficient backwashing with low cost. The filtration system of the present invention comprises; a first filtration tank having a first floating filter media layer, a first upper screen with a first aperture ratio, the first upper screen being disposed over the first floating filter media layer and supporting the floating filter media, a first inlet for water to be treated disposed below the first floating filter media layer, a first backwash water supply source located over the first upper screen, and a first backwash water outlet means disposed below the first floating filter media layer; and a second filtration tank having a second floating filter media layer, a second upper screen with a second aperture ratio, the second upper screen being disposed over the second floating filter media layer and supporting the floating filter media, a second inlet for water to be treated disposed below the second floating filter media layer, an inflow blocking mechanism capable of blocking inflow of water to be treated through the second inlet for water to be treated, a second backwash water supply source located over the second upper screen, and a second backwash water outlet means disposed below the second floating filter media layer, in which the first aperture ratio is smaller than the second aperture ratio.
摘要翻译： 本发明的目的是提供一种过滤系统，其能够以低成本实现浮动过滤介质层的均匀反冲洗和高效反冲洗。 本发明的过滤系统包括： 具有第一浮动过滤介质层的第一过滤槽，具有第一孔径比的第一上部筛网，所述第一上部筛网设置在所述第一浮动过滤介质层上方并支撑所述浮动过滤介质，用于待处理水的第一入口 布置在第一漂浮过滤介质层下方的第一反洗水供应源，以及布置在第一漂浮过滤介质层下方的第一反洗水出口装置; 以及具有第二浮动过滤介质层，具有第二孔径比的第二上部筛网，所述第二上部筛网设置在所述第二浮动过滤介质层上并支撑所述浮动过滤介质，第二入口用于使水成为 所述流入阻断机构能够阻止待处理水通过所述第二待处理水入口流入，第二反洗水供给源位于所述第二上过滤网上方，以及第二反洗 设置在第二浮动过滤介质层下方的出水口装置，其中第一开口率小于第二开口率。
