A switching valve 38 for switching operation is provided.

When the supply pipe 32 extends in a straight line and the ejection nozzles 33 are arranged in a line along the supply pipe 32, the blue injection nozzle 33 receives the ejection nozzle 33 where the odor gas flowing from the supply pipe 32 first meets. The switching valve 38 is preferably an opening / closing valve provided between the wave guide nozzle 33a and the jet nozzle 33.

Accordingly, when the switching valve 38 is closed, no odor gas is supplied to the jet nozzle 33 except the blue induction nozzle 33a, and all the odor gases in the supply pipe 32 are at high pressure. ) Is ejected from only), the bubbles of high pressure are momentarily injected from one side of the deodorizing tank (10, 20).

As described above, when the malodorous gas is supplied only to the wave induction nozzle 33a, the blue water is induced at the surface of the deodorizing liquid 55 by the ejection pressure of the malodorous gas, and the swelling of the blue at the walls of the deodorizing water tanks 10 and 20. It causes a large water level change in a moment, and induces the rise of the deodorizing liquid 55 through the deodorizing liquid passing hole (84).

When the supply of odor gas through the supply pipe 32 occurs several times intermittently and the intermittent pressure ejection occurs through the wave guide nozzle 33a, the generation of the blue wave and the change in the water level can be maximized.

Subsequently, when the deodorizing liquid 55 rises through the deodorizing liquid passing hole 84 by the blue and hits the inclined surface 82a, the deodorizing liquid 55 is partially deodorized above the scum removing layer 81 by the induction of the inclined surface 82a. 55 moves and falls again while passing through the scum removing layer 81 at the upper side of the scum removing layer 81.

This action is to destroy the deodorizing liquid 55 falling from above the bubble 57 to grow through the scum removing layer 81, it is possible to suppress the growth of the bubble (57).

Meanwhile, referring to FIGS. 4 and 5, in this embodiment, the upper surface of the scum removing layer 81 is covered, and a receiving space 85a having an open upper surface is formed, and a leak hole (the bottom of the receiving space 85a is formed). 85c) may be further provided with a deodorant receiving plate 85 is a plurality of distribution.

The deodorizing liquid receiving plate 85 is preferably laminated in contact with the upper surface of the scum removing layer 81 in a plate shape, and covers the scum removing layer 81 in a uniformly dispersed state without covering all of the scum removing layer 81. It does not prevent the odor-depleted gas from rising through (81).

To this end, the deodorant receiving plate 85 has a plurality of leg portions (85b) arranged side by side at a predetermined interval to uniformly cover the scum removing layer 81 in a dispersed structure, the receiving space (85a) a plurality Extending to the upper surface of the leg portion (85b) of all the receiving space (85a) is connected. Moreover, many leak holes 85c in which the deodorizing liquid 55 falls also in each of the some leg part 85b are distributed in the bottom.

Accordingly, a portion of the deodorant liquid 55 moved to the upper side of the scum removing layer 81 is received in the accommodating space 85a, and the contained deodorant liquid 55 moves to each leg portion 85b and is leaked. It can fall to the scum removal layer 81 through the ball 85c.

Thus, the deodorizing liquid 55 falls in the dispersed state in the entire scum removing layer 81 and is more evenly dispersed in the entire area while passing through the fillers of the scum removing layer 81. By this action, the deodorizing liquid receiving plate 85 can disperse the position where the deodorizing liquid 55 falls in the scum removing layer 81, and can effectively suppress the growth of the bubbles 57 on the entire water surface.

In addition, the deodorizing liquid receiving plate 85 prevents the deodorizing liquid 55, which has been hit by the deodorizing liquid inducing member 82 and moved to the upper side of the scum removing layer 81, temporarily falls off and is placed in the receiving space 85a. Since the dropping through the exposure hole while staying for a predetermined time, it is possible to delay the falling time of the deodorizing liquid 55 and to continuously destroy the bubbles 57 continuously generated.
