  The present invention relates to a water treatment apparatus that houses a water treatment mechanism for treating water to be treated in a tank body, and more particularly, is effective for facilitating storage and transportation of an upper tank or a lower tank constituting the tank body. It is about technology.

Conventionally, various configurations for facilitating storage and transportation of an upper tank or a lower tank before joining have been proposed for a flange-joined purification tank formed by joining flange surfaces of an upper tank and a lower tank. For example, Patent Document 1 below presents the possibility of stacking a plurality of tanks without using a spacer or the like by devising the shape of the corrugation formed on the side surface of the upper tank or the lower tank of the septic tank. Yes.
Japanese Utility Model Publication No. 5-13596

By the way, when stacking the upper tank or the lower tank constituting this kind of septic tank during storage or transportation, the stacking state is stabilized by the well-balanced stacking of the stacking object as well as improving the workability of the stacking work. There is a request to make it. However, although the septic tank described in Patent Document 1 certainly has the possibility of stacking a plurality of tanks without using spacers or the like, it is not configured to improve balance at the time of stacking, and the stacked state is It is difficult to stabilize.
Therefore, the present invention has been made in view of such points, and can efficiently stack the upper tank or the lower tank constituting the tank body of the water treatment apparatus and stabilize the stacked state. It is an object to provide an effective technique for this.

  The present invention is configured to solve the above problems. In addition, this invention is a technique which can be applied to the water treatment apparatus which accommodates the water treatment mechanism which processes various to-be-processed water including the domestic waste water discharged | emitted from a general household etc. in a tank main body.

(First invention of the present invention)
1st invention of this invention which solves the said subject is a water treatment apparatus as described in Claim 1. FIG. The water treatment device according to claim 1 is configured as a device that houses a water treatment mechanism for treating the water to be treated in the tank body. The “water treatment mechanism” here is a mechanism for treating various types of water to be treated. Typically, a solid-liquid separation processing unit, a biological processing unit, a storage processing unit, a transfer processing unit, a disinfection processing unit. Etc. are appropriately combined. The tank body is composed of a bowl-shaped upper tank and lower tank whose plan view is substantially rectangular, and has a flange-joined configuration formed by overlapping and bonding the bonding flange surfaces of the upper tank and the lower tank. It has become.

  In the tank main body of the present invention, at least one of the upper tank and the lower tank includes a plurality of corrugated portions whose side wall surfaces are recessed toward the inner peripheral side.

  In the embodiment shown in FIGS. 12 and 13, an inclined configuration (see FIG. 14) in which the upper interval c among the intervals of the inserted portion 125 is expanded more than the lower interval a can be used. . According to such a configuration, the corrugated portions 121 and 122 involved in the stacking of the lower tank 120 can be used for the partition plate guide, the partition plate stopper, and the partition plate fixing, and further inserted. By widening the gap on the insertion opening side of the portion 125, the partition plate 130 can be smoothly guided to the inserted portion 125, and applied to the inserted portion 125 in advance for adhesion of the partition plate 130. It is possible to suppress the adhesive material from being scraped when the partition plate 130 is inserted.

[Other Embodiments]
In addition, this invention is not limited only to said embodiment, A various application and deformation | transformation can be considered. For example, each of the following embodiments to which the above embodiment is applied can be implemented.

  In the said embodiment, although the corrugated shape in the lower tank of a tank main body was described, this invention can also be applied with respect to the structure of an upper tank. Moreover, the corrugated shape of this invention can be used regarding the structure which stacks lower tanks, the structure which stacks upper tanks, and the structure which stacks an upper tank and a lower tank. Moreover, in the said embodiment, although the corrugated shape in the side wall surface of the long side part of a lower tank was described, this invention can also be applied with respect to the corrugated shape in the side wall surface of the short side part of a lower tank.

  In the above embodiment, for example, in the lower tub 120, the case where the position of the upper end portion 121a of the first corrugated portion 121 in the height direction substantially matches the position of the joining flange surface of the joining flange 120a is described. In the invention, the position of the upper end portion 121a of the first corrugated portion 121 may substantially match the position of the joining flange surface, or may be appropriately set below the position of the joining flange surface.

  In the present invention, among the plurality of corrugated portions provided on the side wall surface of the tank, all or a part of the corrugated parts may be any corrugated part that is involved in stacking. For example, all corrugated parts on the side wall surface of the tank are involved in stacking. The structure which does may be sufficient, or the structure where the corrugated part which is concerned in stacking, and the corrugated part which is not involved in stacking may coexist.
