A treatment tank 10 in which water is stored, and a washing pump 30 connected to the treatment tank 10 to pump the treatment water 11 in the treatment tank 10 to the supply pipe 24 side.

A suction pipe 31 is connected between the washing pump 30 and the treatment tank 10 to supply the treatment water 11 in the treatment tank 10 to the washing pump 30, and the washing pump 30 and the supply pipe. The connection pipe 32 is connected between the 24 so that the treated water 11 sucked from the suction pipe 31 is pumped toward the supply pipe 24.

On the other hand, the strainer (strainer) 34 is installed on the connecting pipe 32, if the dirt or foreign matter enters the cleaning nozzle 26 through the supply pipe 24, there is a fear that the cleaning nozzle 26 is clogged, in this case the cleaning is well May not be. Therefore, when the strainer 34 is installed on the connection pipe 32, the dust or foreign matter contained in the treated water may be filtered by the metal mesh inside the strainer 34. Such a strainer 34 is installed to be assembled and disassembled in the connecting pipe 32 so that it can be cleaned periodically inside.

The sludge hopper 28 having an outlet 29 is installed at the lower part of the washing nozzle 26. When the chlorine liquid washing operation to be described later is performed, sludge such as foreign substances and sterilized microorganisms falling from the filtration filter 22 are disposed therein. The sludge received is stored and conveyed to the water collection tank through the outlet 29 of the sludge hopper 28.

The chemical supply means includes a dissolution tank 40 in which chemicals are dissolved and stored, a chlorine liquid supply pipe 42 connected to the dissolution tank 40 and a connection pipe 32, and a supply installed on the chlorine liquid supply pipe 42. It is divided into a metering pump 44 which is a means.

Here, the drug is any one of chlorine, hypochlorous acid, hydrochloric acid, and any drug having a similar bactericidal power may be used, and hereinafter, only chlorine will be described for convenience.

The dissolution tank 40 may contain a chlorine solution in a dissolved state, but may be stored in the dissolution tank 40 by a stirring blade, a drive shaft connected to the stirring blade, and a drive motor connected to the drive shaft to rotate it. In this case, chlorine and a solvent may be added to the dissolution tank 40 to properly dissolve therein.

The chlorine liquid supply pipe 42 has one end connected to the connection pipe 32 between the supply pipe 24 and the strainer 34 and one end is installed at the lower end of the dissolution tank 40, so that the chlorine liquid properly dissolved is connected to the connection pipe 32. It is to be supplied to the supply pipe 24 through.

Since the other end of the chlorine solution supply pipe 42 is connected to the connecting pipe 32 between the supply pipe 24 and the strainer 34, the chlorine solution is mixed with the treated water filtered by the strainer 34 and diluted. The diluted chlorine liquid is supplied to the washing nozzle 26.

The metering pump 44 is electrically connected to the washing pump 30 so that the washing pump 30 is operated together with the washing pump 30, and the washing pump 30 is stopped when the washing pump 30 is stopped. Therefore, since the metering pump 44 is driven only when the washing pump 30 is driven, a constant ratio of chlorine liquid is always diluted in the treated water supplied to the washing nozzle 26. Therefore, the problem of excessive input of chlorine liquid to the treated water is prevented.

The chemical washing apparatus for removing organic and inorganic substances attached to the media of the disk filter of the present invention having such a configuration includes a filtration filter while being filtered by the filtration filter 22 while the wastewater is introduced into the inlet of the drum and discharged to the outlet. 22) foreign substances, such as organic and inorganic substances, adhere to each other, and the pores of the filtration filter 22 are blocked by such foreign substances, so that the permeation rate of the wastewater is decreased, and the water level in the treated water tank is increased. The water level sensor detects this. Therefore, the disk filter is rotated and the washing pump 30 and the metering pump 44 are driven.

When the washing pump 30 is driven, the treated water 11 in the treated water tank 10 is introduced into the suction pipe 31 and then supplied to the supply pipe 24 through the connecting pipe 32, and at this time, to the metering pump 44. The chlorine liquid in the dissolution tank 40 is supplied to the connection pipe 32 through the chlorine liquid supply pipe 42.

The treatment water 51 and the chlorine are introduced into the tub 60, and thus the treated water 51 in the treatment tank 50 is introduced through the inlet 61 of the mixing tub 60. The liquid is mixed. The mixed and diluted chlorine liquid is supplied to the washing nozzle 74 through the connecting pipe 72 and the supply pipe 73 by the washing pump 70.

In the present invention described above, since the chlorine liquid in the dissolution tank 80 is introduced into the mixing vessel 60, the chlorine liquid is prevented from spreading to the entire treatment tank 50. That is, when the chlorine liquid is supplied to the lower portion of the suction pipe 71 of the washing pump 70 in a state in which the mixing container 60 is not provided, a part of the chlorine liquid will be introduced into the suction pipe 71, but the remaining portion of the treatment tank 50 is full.

That is, the washing pump 30, 70 of Figures 3 and 4 should use a high pressure pump because the treated water must be injected strongly to the washing nozzle (26) (74) side. Therefore, the metering pump 44 of FIG. 3 should be pumped in proportion to the treated water pumped in large quantities at high pressure, and therefore, a high pressure pump, such as the washing pump 30, should be used.

On the other hand, the metering pump 81 of FIG. 4 may use a low pressure pump, and the role of the washing pump 70 of FIG. 4 is not only pumping the treated water at high pressure, but diluted in the mixing vessel 60. Pump chlorine at high pressure. Therefore, the metering pump 81 of FIG. 4 may use a low pressure pump, and only needs to supply chlorine liquid in proportion to the amount of treated water flowing into the mixing cylinder 60.

That is, the chemical supply means of FIGS. 3 and 4 is a supply method by the metering pumps 44 and 81, while the chemical supply means of FIG. 5 is a supply method by an ejector 100.

In the present invention, when the treated water 91 in the treated water tank 90 is pumped by the washing pump 92, the chlorine liquid in the dissolution tank 96 is injected to the supply pipe 94 by the pumping pressure. 94, the dissolution tank 96, the washing pump 92 is connected to the ejector 100. That is, the ejector 100 is installed in the connection pipe 93 connecting the washing pump 92 and the supply pipe 94, and the chlorine liquid supply pipe 97 is connected to the ejector 100 and the dissolution tank 96.

Therefore, when the washing pump 92 is driven and the treated water 91 in the treated water tank 90 is pumped through the ejector 100 through the connecting pipe 93 to the supply pipe 94, the dissolution tank by the pumping pressure. Chlorine liquid in 96 is sucked into the ejector 100. Therefore, the chlorine liquid sucked into the ejector 100 and the treated water passing through the ejector 100 are mixed and diluted, and the diluted chlorine liquid is supplied to the supply pipe 94 and the washing nozzle 95.

Such the present invention is different from the drug supply method only compared to FIGS. 3 and 4, the rest of the configuration, operation, and effects are the same.
