Detailed description of the invention
Below, be described with reference to the preferred embodiment of accompanying drawing to equipment for separating liquid from solid of the present invention.In addition, in the embodiment shown in Fig. 1 to Fig. 7, flocculation deposition apparatus is illustrated as equipment for separating liquid from solid.But equipment for separating liquid from solid is not limited to flocculation deposition apparatus.Namely, if the processed water introduction part had for importing processed water and catch from processed water introduction part import processed water solid and flocculate growth district flocculate being grown up by processed water, the structure of equipment for separating liquid from solid is not particularly limited.
Fig. 1 is the summary construction diagram of the flocculation deposition apparatus represented involved by the 1st embodiment of the present invention, and Fig. 2 is the top view of the flocculation deposition apparatus shown in Fig. 1, and Fig. 3 is the stereogram representing inner core tank in Fig. 1 and Fig. 2 and dividing plate.
As shown in Figure 1, the flocculation deposition apparatus (equipment for separating liquid from solid) 100 of present embodiment possesses: the urceolus tank 1 of bottomed cylindrical, diameter are less than this urceolus tank 1 and are highly also less than this urceolus tank and are contained in the inner core tank 2 of the bottomed cylindrical of the inside of this urceolus tank 1 with coaxial manner.In this flocculation deposition apparatus 100, the bottom (bottom the 2nd) of inner core tank 2 relative to bottom (bottom the 1st) the spaced apart predetermined distance upward of urceolus tank 1, thus in double-layer water tank structure.In addition, at this, urceolus tank 1 and inner core tank 2 are set to cylindrical shape, but also can be set to square tube shape.
For the ingress pipe (processed water introduction part) 4 in former water (processed water) lead-in groove being inserted the groove perisporium of urceolus tank 1 bottom, and insert the groove perisporium of the bottom of inner core tank 2 and enter in this inner core tank 2.At this, former water such as mixing the solution of the inorganic flocculating agents such as such as PAC (polyaluminium chloride) in organic wastewater.Further, the flocculant feeding pipe L1 for supplying the high polymer coagulants such as such as anion based polymer is connected with at ingress pipe 4.
At this, especially in the present embodiment, as shown in Figure 1 to Figure 3, the multiple dividing plates 3 circumferentially the zone line R of the ring-type be formed between urceolus tank 1 and inner core tank 2 (cylindrical shape) being divided into multiple region are provided with.At this, dividing plate 3 is 2, and zone line R is divided into 2 regions by this dividing plate 3, i.e. a region R1 (sinking district) and another region (adjacent area, Upwelling Region) R2.The outboard end of these dividing plates 3,3 and the inner peripheral surface of urceolus tank 1 link, and the outer peripheral face of its medial end and inner core tank 2 links, and thus inner core tank 2 is linked to urceolus tank 1.Dividing plate 3 is arranged to lower end from the upper end of inner core tank 2, and the inner core tank upper end U1 corresponding with the region R1 separated by this dividing plate 3 is set as the inner core tank upper end U2 lower than adjacent area R2, at this, is set as low about 1 ~ 100cm.
