Description
揚水部13は旋回流式沈砂池70A,70Bの集砂部72A,72Bに沈降した砂Sを吸い込み、旋回流式沈砂池70A,70Bの外に排出する。揚水部13は、旋回流式沈砂池70A,70Bの外部に配置されている。揚水部13は、ジェットポンプ18と、タンク19と、タンク19に接続された圧力ポンプ21とを有している。圧力ポンプ21はジェットポンプ18に所定の圧力を有する圧力水を供給するものであり、所定の圧力は所望の値に制御可能に構成されている。ジェットポンプ18に供給された圧力水は、ジェットポンプ18内の噴射室に噴射され、高圧の水の噴射により生じるエジェクタ作用(いわゆるジェットポンプ作用)がジェットポンプ18内に生じる。このエジェクタ効果によりジェットポンプ18は、集砂部72A,72Bに沈降した砂Sを砂S付近の被処理水Wと共に吸い込み、固液分離装置79へ排出する。 The pumping unit 13 sucks the sand S settled in the sand collecting portions 72A and 72B of the swirling flow type sand basins 70A and 70B, and discharges it to the outside of the swirling flow type sand basins 70A and 70B. The pumping unit 13 is disposed outside the swirling flow type sand basins 70A and 70B. The pumping unit 13 includes a jet pump 18, a tank 19, and a pressure pump 21 connected to the tank 19. The pressure pump 21 supplies pressure water having a predetermined pressure to the jet pump 18, and the predetermined pressure can be controlled to a desired value. The pressure water supplied to the jet pump 18 is injected into an injection chamber in the jet pump 18, and an ejector action (so-called jet pump action) generated by the injection of high-pressure water occurs in the jet pump 18. Due to this ejector effect, the jet pump 18 sucks the sand S that has settled in the sand collecting portions 72 </ b> A and 72 </ b> B together with the water W to be treated near the sand S and discharges it to the solid-liquid separator 79.
第3実施形態に係る揚砂装置3は、曝気式沈砂池90Aに配置された吸込管11Aと、曝気式沈砂池90Aに配置された吸込管11Bと、吸込管切替部12と、揚水部13と、曝気式沈砂池90Aに配置された集砂装置82Aと、曝気式沈砂池90Bに配置された集砂装置82Bとを備えている。揚砂装置3は、さらに、曝気式沈砂池90Aに配置された曝気装置92Aと、曝気式沈砂池90Bに配置された曝気装置92Bを備えている。すなわち、第3実施形態に係る揚砂装置3は、第2実施形態に係る揚砂装置2が曝気装置92A,92Bをさらに備えたものである。 The sand pumping device 3 according to the third embodiment includes a suction pipe 11A disposed in the aeration type sand basin 90A, a suction pipe 11B disposed in the aeration type sand basin 90A, a suction pipe switching unit 12, and a pumping unit 13. And a sand collecting device 82A disposed in the aeration-type sand basin 90A and a sand collecting device 82B disposed in the aeration-type sand basin 90B. The sand raising device 3 further includes an aeration device 92A arranged in the aeration type sand basin 90A and an aeration device 92B arranged in the aeration type sand basin 90B. That is, in the sand raising device 3 according to the third embodiment, the sand raising device 2 according to the second embodiment further includes aeration devices 92A and 92B.
