Problems solved by technology

However, due to the high content of suspended solids such as sediment and inorganic or organic waste in the river, conventional seepage dams are more prone to clogging; and because the water flow direction and purification methods in conventional seepage dams are relatively simple, the water purification capacity is limited , it is often necessary to use multi-stage infiltration dams to achieve better purification effects

Abstract

The invention discloses an anti-blocking baffling type percolation dam which comprises a retaining dam body, a downstream percolation area, a partition wall, an upstream percolation area and a side wall. A water body in a river channel flows into the downstream percolation area through a water inlet inclined pipe arranged on the retaining dam body, then passes through a water passing hole in the bottom of the partition wall to flow into the upstream percolation area and flows out of the top of the upstream percolation area. The water inlet inclined pipe is adopted for water inputting, the upstream and downstream baffling mode is adopted in the percolation areas, emerging and sinking multi-element vegetable layers are adopted, and the dam has the advantages of being good in anti-blocking effect, high in filtering efficiency and good in purification and landscape effect.

Description

technical field [0001] The invention relates to the technical field of river channel environment treatment, in particular to an anti-clogging deflection type seepage dam. Background technique [0002] Seepage dams are mostly made of concrete blocks, block stones, gravel, etc., which not only have the function of intercepting water body and regulating flow, but also have certain water purification ability through the comprehensive effect of filler filtration and biochemical degradation of microorganisms growing in the filler. It is widely used in river ecological management. However, due to the high content of suspended solids such as sediment and inorganic or organic waste in the river, conventional seepage dams are more prone to clogging; and because the water flow direction and purification methods in conventional seepage dams are relatively simple, the water purification capacity is limited , It is often necessary to use multi-stage infiltration dams to achieve better pu...
