＜浄化装置２００の全体構成＞
図１は、本発明の実施形態における浄化装置２００の全体構成図である。浄化装置２００は、原水を貯留する原水池３００の原水中の汚泥を除去することにより原水池３００の浄化を行う浄化装置であって、ゼオライト系の凝集剤粉末を連続的に投入可能な凝集剤投入機１０、凝集剤粉末が投下された原水を渦流で攪拌する第１の攪拌機２０、内壁への衝突による再攪拌を行う第２の攪拌機３０、第１の攪拌機２０による攪拌後の原水を一時貯留する揚水タンク４０、２段階の沈殿濾過を行う第１の沈殿濾過槽５０及び第２の沈殿濾過槽６０を含む。 <Overall configuration of purification device 200>
Figure 1 is an overall configuration diagram of a purifying apparatus 200 according to an embodiment of the present invention. The purification device 200 is a purification device that purifies the raw water pond 300 by removing sludge in the raw water of the raw water pond 300 that stores the raw water, and is a flocculant capable of continuously adding zeolite-based flocculant powder. The feeder 10, the first stirrer 20 that stirs the raw water on which the flocculant powder has been dropped by vortex, the second stirrer 30 that performs re-stirring by collision with the inner wall, and the raw water that has been stirred by the first stirrer 20 temporarily A pumping tank 40 to be stored, a first precipitation filtration tank 50 that performs two-stage precipitation filtration, and a second precipitation filtration tank 60 are included.

第１の沈殿濾過槽５０は、その上壁から底部の上方まで延びた隔壁５１によって仕切られており、第２の攪拌機３０から第１の沈殿濾過槽５０内に落下した水は隔壁５１を回り込んで、隔壁５１の左側の空間に設けられた濾過層５２を下から上に通過するようになっている。これにより、原水は、濾過層５２で濾過されるとともに、原水に含まれた汚泥５３が第１の沈殿濾過槽５０の底部に沈殿する。沈殿した汚泥５３は第１の沈殿濾過槽５０の底に接続された汚泥管５４を通して汚泥タンク７０に送られる。汚泥タンク７０の底部７１には汚泥５３が貯まるが、上澄み水は配管７２を通して揚水タンク４０に戻される。 The first precipitation filtration tank 50 is partitioned by a partition wall 51 extending from the upper wall to the upper part of the bottom, and the water that has fallen into the first precipitation filtration tank 50 from the second stirrer 30 passes around the partition wall 51. The filter layer 52 provided in the space on the left side of the partition wall 51 is passed from the bottom to the top. As a result, the raw water is filtered by the filtration layer 52 and the sludge 53 contained in the raw water is precipitated at the bottom of the first precipitation filtration tank 50. The sedimented sludge 53 is sent to the sludge tank 70 through a sludge pipe 54 connected to the bottom of the first sedimentation filtration tank 50. Sludge 53 is stored in the bottom 71 of the sludge tank 70, but the supernatant water is returned to the pumped tank 40 through the pipe 72.

そして、脱水筒９８内に汚泥コンベア８０から汚泥５３が搬入されて、基台９７の上動により脱水蓋９４で汚泥が垂直方向に圧縮されることにより、汚泥５３の水分が排水管９６から排出されるように構成されている。排水管９６から排出された水は、排水管９６を通して原水池３００に戻されることが好ましい。脱水されて粉末化した汚泥５３は小形軽量化されていることから袋などに詰め込んだ状態で運搬するのに適しており、脱水筒９８から取り出され、廃棄場所や仮置き場に運搬される。 Then, the sludge 53 is carried into the dewatering cylinder 98 from the sludge conveyor 80, and the sludge is vertically compressed by the dewatering lid 94 by the upward movement of the base 97 , whereby the moisture of the sludge 53 is discharged from the drain pipe 96. It is configured to be. The water discharged from the drain pipe 96 is preferably returned to the raw water basin 300 through the drain pipe 96. The dewatered and powdered sludge 53 is suitable for transporting in a state of being packed in a bag or the like because it is reduced in size and weight, and is taken out from the dewatering cylinder 98 and transported to a disposal place or a temporary storage place.

Claims

The precipitate filter tank is connected via a sludge tube, purifying apparatus according to claim 1, characterized in that it comprises a sludge tank for storing the precipitated sludge into the sedimentation filter tank.

The purification apparatus according to any one of claims 1 to 5, further comprising a sludge delivery pump for sending the sludge precipitated in the precipitation filtration tank to the sludge tank.
