POLLUTANT TRAPPING STRUCTURE AND POLLUTANT TRAPPING EQUIPMENT
To suppress the outflow amount of pollutants captured in a lower chamber.SOLUTION: A pollutant trapping structure 1 comprises a weir part 8 attached to a partition floor 7 of a treatment tank 4 which is partitioned into an upper chamber 5 and a lower chamber 6 by the partition floor 7, and dams wastewater flowing into a first area A1 on the partition floor 7 so as to overflow to a second area A2, an inlet part 9 through which wastewater dammed by the weir part 8 flows into the lower chamber 6, and an outlet part 10 that allows wastewater in the lower chamber 6 to flow to the second area A2. The inlet part 9 has a water conduit pipe 9a that is attached to pass through the partition floor 7 from top to bottom and guides wastewater to the lower chamber 6 as a swirl. The outlet part 10 has a pipe member that is attached to vertically penetrate the partition floor 7 and extends below the lower end of the water conduit pipe 9a. The pipe member includes a first pipe member 11 constituting an upper portion and a second pipe member 12 constituting a lower portion. The second pipe member 12 has a plurality of inflow holes 12X passing through a pipe wall.SELECTED DRAWING: Figure 1
【課題】下部室で補足した汚濁物の流出量を抑制する。【解決手段】汚濁物捕捉用構造体１は、区画床７によって上部室５と下部室６とに区画された処理槽４の当該区画床７に取り付けられ、区画床７上の第１領域Ａ１に流入する廃水を第２領域Ａ２へと越流可能に堰き止める堰部８と、堰部８によって堰き止められた廃水を下部室６へ流す入口部９と、下部室６内の廃水を第２領域Ａ２へ流す出口部１０と、を備え、入口部９は、区画床７を上下貫通して取り付けられ廃水を渦流として下部室６へと導く導水管９ａを有し、出口部１０は、区画床７を上下貫通して取り付けられ導水管９ａの下端より下方まで延びる管部材を有し、管部材は、上部を構成する第１管部材１１と下部を構成する第２管部材１２とを含み、第２管部材１２は、管壁を貫通する複数の流入孔１２Ｘを有する。【選択図】図１
