Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to an apparatus that processes water containing impurities, germs, etc., removes impurities, kills germs, and makes it odorless to obtain clean water.

[Conventional technology]

Conventionally, it has been common practice to add chemicals to water, mix them, and filter the mixture to obtain clean water. However, it is impossible to remove chemicals mixed into the water and the odor inherent in the chemicals, and a large amount of chemicals must be used to sterilize the water. There was no way. In JP-A No. 56-95387, as a method of reusing treated water for tofu production, suspended matter in the water to be treated is removed using a primary filter, and sterilized in an ultraviolet sterilization cylinder to remove the diatomaceous earth layer attached to the surface of the filter cloth and the active The carbon layer deodorizes, decolorizes, and removes drugs and suspended matter. Furthermore, Japanese Patent Publication No. 53-137 discloses a cylindrical filtration element constructed by weaving metal filaments made of stainless steel or the like having restoring elasticity obliquely to the axis of the cylindrical filtration element. ing. In addition, in Japanese Patent Application Laid-open No. 60-99391,
A water quality conversion filter has been disclosed in which a composite composite of many metals such as Ca, Mg, K, Na, Si, Al, Fe, Ni, Mn, etc. is stacked on ceramic pieces using a binder. However, in the present invention, the first body filter, the first filter aid tank, the first deodorized ceramic tank, the ultraviolet sterilizer, the second deodorized ceramic tank, the treated water circulation circuit of the treated water curing tank, and the treated water curing tank. Since there is a lack of a circulation circuit between the second body filter and the second odorless ceramic tank provided on the discharge side, it is impossible to ensure water that is sterile and odorless.

[Effect]

The present invention mixes a filter aid with untreated water containing impurities (sludge) and sends the mixture to a first main body filter, and then mixes the mixture with a cylindrical filter cloth and a coil spring suspended inside the first main body filter. The filter aid was filtered through a septum-like filter cloth to separate the filter aid and impurities were removed, and the filter aid supplied in the first filter aid tank was used to filter and repeat the circulation to remove the impurities. The treated water is sent to the first deodorizing ceramic tank to become odorless water, and this impurity is removed and the odorless treated water is sent to an ultraviolet sterilizer for sterilization, which removes these impurities, makes it odorless, and sterilizes it. The treated water is further stored in a treated water curing tank through the deodorized ceramic of the second deodorized ceramic tank, and the first body filter, the first deodorized ceramic tank, the ultraviolet sterilizer, and the second deodorized ceramic tank are further stored in the treated water curing tank. The filter is circulated and then filtered using a filter aid supplied from a second filter aid tank through a cylindrical filter cloth and a partition-like filter cloth with a coil spring suspended inside the second main body filter. This is repeated to supply water that is sterile, odorless, and clean.

【effect】

Water supply: When the water level in the treated water curing tank F drops, the automatic power switch SW operates and the solenoid valve G opens to automatically supply water. Removal of impurities: When untreated water containing impurities passes through the first main body filter A1, impurities are captured and removed by the partition filter cloth and the bottomed cylindrical filter cloth, which have been protectively coated with a filter aid in advance. Deodorization: Deodorized ceramic 8 in the first deodorized ceramic tank C and the second deodorized ceramic tank E
The water is made odorless by contacting it with odorized water. Sterilization: Ultraviolet light (with a peak wavelength of 253.7 mm) is generated from the ultraviolet generator tube d of the ultraviolet sterilizer D and irradiated onto the sterile water passing through the ultraviolet sterilizer D. The sterilizing power of this ultraviolet ray kills bacteria in the water. It can be killed to obtain sterile water. Circulation circuit: The treated water stored in the treated water curing tank F is passed through the circulation circuit of pipe 7, water supply inlet pipe 1, filtered water outlet pipe 2, and pipe 6 to the first main body filter A1, the first deodorized ceramic tank C, and the ultraviolet rays. Return to sterilizer D and second odorless ceramic tank E for reprocessing. By doing so, the production of treated water will be promoted. Promotion and reinforcement of filtration: Vibration is applied to the springs S and S1 provided in the first main filter and the second main filter to further enhance the filtration effect and prevent clogging.
