A relay tank 20 is usually provided after the sand removing device 19. The relay tank 20 includes the sand removal device 1.
This can be omitted if the liquid can be introduced from 9 to the next liquid fertilizer raw material storage tank 21 or maturation tank 10 under natural flow through the filtrate transfer pipe line 19o after sand removal. The relay tank 20
Then, the liquid fertilizer raw material liquid is transferred to the next liquid fertilizer raw material storage tank 21 or the maturation tank 10 via the liquid submersible pump 20p and the transfer pipeline 20o.

[0007] The liquid fertilizer raw material storage tank 21 is used for the treatment of the present invention when the receiving time interval of the waste liquid containing the organic matter such as animal manure greatly varies and is unstable, or when it is impossible to receive the waste liquid for a long time in winter in a heavy snowfall area. In order to ensure continuous operation of the apparatus, particularly the maturation tank 10, the liquid fertilizer raw material to be supplied to the maturation tank 10 is stored and provided to have a function as a buffer. The liquid fertilizer raw material storage tank 21 is not required when the time interval for receiving waste liquid containing organic matter such as animal manure is small and stable.

The liquid fertilizer storage tank 12 has a compressed air source 18a.

In the case where 0 and / or the liquid fertilizer raw material storage tank 21 is provided, unless efficient stirring is performed, as in the case of the liquid fertilizer storage tank 12, sedimentation / accumulation of suspended inorganic or organic solid components occurs, Reduction of actual volume in each tank and maturation tank 10
There is a problem that the liquid component of the liquid fertilizer raw material fed to the variance causes a temporal variation, and consequently a temporal variation of the liquid fertilizer component carried out.

[0011]

In the above-described apparatus of the present invention, an air blowing type stirring device 18 is used as a stirring device for the stored liquid fertilizer in the liquid fertilizer storage tank 12. According to the study of the present inventors, the following disadvantages are found. It was found to have

(1) Nozzle header 18 for discharging air
The solids around c can be rolled up to expect a stirring effect, but the distance between the nozzle header and the adjacent nozzle header is large, resulting in poor stirring. (2) Since the nozzle header 18c is fixed, there is a portion that becomes a dead space for stirring. This dead space sediment will always accumulate. (3) In order to increase the stirring effect, it is necessary to arrange a large number of nozzle headers 18c and increase the flow rate of air, and it is necessary to install a blower or a compressor having a large capacity, and to operate it. Costs are high.

When the relay layer 20 and / or the liquid fertilizer raw material storage tank 21 is provided with an air blowing type stirring device 18 in the same manner as the storage liquid fertilizer stirring device in the liquid fertilizer storage tank 12,
A problem similar to the above arises.

The present invention solves the above-mentioned problems of the prior art, and there is no dead space for stirring in the liquid fertilizer storage tank, the actual volume of the storage tank is reduced due to the sedimentation of inorganic substances in the storage tank, and the liquid is discharged. An organic matter-containing waste liquid treatment device equipped with an efficient stirring device, which can prevent the variation of the liquid fertilizer component over time, does not require the installation of a large-capacity blower or compressor, and has a low operating cost. Is the first task.

The present invention also solves the above-mentioned problems of the prior art, and has no dead space for stirring in the relay tank and / or the liquid fertilizer raw material storage tank, and eliminates the solid components of suspended inorganic and organic substances in the storage tank. Due to the sedimentation / sedimentation, the actual volume of each tank is reduced, and the liquid component of the liquid fertilizer raw material fed to the next maturation tank is prevented from varying over time. It is possible to provide an organic matter-containing waste liquid treatment device equipped with an efficient stirring device, which can prevent a natural variation, does not need to install a blower or a compressor having a large capacity, and is inexpensive in operation cost. This is a second problem.
