Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is one in which a water treatment facility is united so that the water treatment facility can be extended and expanded freely.

[Prior Art] In a water treatment facility, as shown in FIG. 3, a first settling tank, an aeration tank or a rotating disk tank, and a final settling tank are usually arranged in series. Even when expansion was planned, each unit was constructed at intervals as shown in Fig. 4 and expanded to fill the gap between the 2nd and 3rd periods. Due to the gaps between them, the construction of the building had to wait until all were completed, and for the time being, it was also necessary to acquire land that was not needed, which required a large amount of initial investment.

[Problems to be Solved by the Invention] The present invention is to increase the degree of freedom with respect to the expansion of a water treatment facility by increasing the basic units of the water treatment facility and adding them as needed.

[Means for solving the problem] The first settling tank, the aeration tank, and the final settling tank, which are the basic units of the water treatment facility, are made into one unit, but the first settling tank and the final settling tank are adjacent to each other. The basic unit is provided with an aeration tank so as to face both of them, and it can be expanded vertically or horizontally or stepwise according to the topography of the site as needed.

[Example] As shown in FIG. 1, a square first settling tank 1 and a square final settling tank 2 are arranged adjacent to each other so as to have a common wall 5, and the above-mentioned galleries which also serve as pump chambers are sandwiched therebetween. The aeration tank or the rotating disk tank is arranged so as to face the two settling tanks of No. 1, and this is the basic unit. A block is formed by horizontally connecting two units symmetrically with each other, and is appropriately connected as needed.

FIG. 2A shows the blocks connected horizontally.
In addition, FIG. 2B is a vertical connection of these blocks.

In this block, the first settling basin and the final settling basin are located close to each other, so both sludge pumps will be installed in common or in common.

At the beginning of opening, the service will start in one block, and when the amount of processing increases, the next block will be connected for two periods to increase the processing capacity.

When one block is completed, building the shed of this facility will not affect the next expansion, so
When the water treatment block is completed, it is safe to start building the shed.

In this embodiment, two units are set as one block, and these blocks are connected to each other so that the facility can be expanded.
It goes without saying that even one unit can be used, and this unit can be added to accommodate expansion.

FIG. 2-3 shows another embodiment. In this embodiment, the settling basin has a circular shape and is arranged concentrically.
Others are the same as in the first embodiment.

[Effect of the invention] The unitization of the water treatment facility where the first settling basin and the final settling basin are located close to each other allows the facility to be expanded as required, and the degree of freedom of expansion is extremely high, and the shape of the site It is possible to expand according to, and it is possible to flexibly cope with future plan changes. Therefore, advanced use of the land becomes possible, and restrictions are also relaxed in securing future land.

As in the present invention, the pumps with the unit type arrangement can be gathered in one place for each block, so that the inspections of the pumps can be centralized and the facilities are arranged close to each other. It becomes easy to grasp the series of processing status for each series.

In this unit type layout, it is possible to build a shed for each unit, so it is possible to construct a shed early and there is an advantage that you do not have to wait until all facilities are completed as in the past. is there.
