The water intake port 1 has a filter 2 disposed inside and is connected to a flow path 4. The flow path 4 is once divided into an ozone sterilization tank side flow path 4a and a biological purification tank side flow path 4b by a switching valve 3, and connected to an ozone sterilization tank 7 and a biological purification tank 10, respectively. Here, in the ozone sterilization tank 7,
An ozone generator 5 and an ozone circulation pump 8 are connected by an ozone flow path 6, and a granular ceramic 9 is disposed inside the biological purification tank 10. Then, the ozone sterilization tank-side flow path 4a and the biological purification tank-side flow path 4b, which have been once separated, merge again after passing through the respective tanks 7 and 10, and become the flow path 4 and are connected to the water circulation pump 11. , And drain port 12. These are all stored in the main body 13.

Here, an outline of the operation of the present purification apparatus will be described.

First, when the purifying apparatus is started, the water circulation pump 11 is driven, and sewage flows into the apparatus from the water inlet 1. At this time, the filter 2 removes large visible dust such as hair.

On the other hand, the switching valve 3 is configured to be able to switch to either the ozone sterilization tank side flow path 4a or the biological purification tank side flow path 4b.
The ozone disinfection tank 7 is switched to the ozone disinfection tank side flow path 4a side.
The sewage is caused to flow into the biological purification tank 10 by switching the switching valve 3 to the biological purification tank side flow path 4b side after a predetermined time has elapsed.

In the ozone sterilization tank 7, after the switching valve 3 is switched to the biological purification tank 10, the ozone generated by the ozone generator 5 is passed through the ozone flow path 6 by the ozone circulation pump 8 to the ozone sterilization tank. And is mixed with the wastewater in the ozone sterilization tank 7. At this time, in order to efficiently sterilize with ozone, it is necessary to sufficiently dissolve ozone in the sewage, but since the flow of water in the ozone sterilization tank 7 has stopped, it is necessary to take sufficient time to remove the ozone from the sewage. Can be dissolved.

Further, in the biological sterilizing tank 10, the surface of the granular ceramic 9 built in advance is provided with some irregularities so that useful microorganisms such as bacteria can be easily propagated. Biological purification is carried out by useful microorganisms such as bacteria that have propagated in the country. Then, the ozone sterilization tank side flow path 4a and the biological purification tank side flow path 4

According to the purification device of the first embodiment,
Once the sewage flows into the ozone sterilization tank 7 and then the switching valve 3 is switched to the biological purification tank 10 side, the sewage accumulated in the ozone sterilization tank 7 is sterilized. It can be carried out. Further, since the flow paths 4a and 4b between the ozone sterilization tank 7 and the biological purification tank 10 are divided, the water mixed with ozone in the ozone sterilization tank 7 flows into the biological purification tank 10, and There is no danger of killing the breeding useful microorganisms. In addition, since the ozone sterilization tank 7 is disposed immediately after the filter 2 as the water absorbing means and the switching valve 3 as the switching means, the flow path to the drain port 12 can be set sufficiently long, and , The reaction time can be further prolonged, and efficient sterilization can be performed. In addition, since the switching valve 3 is provided in front of the flow paths 4a and 4b between the ozone sterilization tank 7 and the biological purification tank 10, for example, when the flow is switched to the biological purification tank 10 side, the water is immediately transferred to the ozone layer 7 side. The inflow is stopped and the sterilization process described above can be started.

Next, a purification apparatus according to a second embodiment of the present invention will be described with reference to the block diagram of FIG.

In the purification device of the second embodiment, as shown in the block diagram of FIG.
Control means for controlling the timing of switching

The present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention.

For example, in the first embodiment, the ozone circulation pump 8 is used to make ozone flow, but any method may be used as long as the generated ozone flows into the ozone sterilization tank 7. For example, by using a water circulation pump 11 to generate a negative pressure to draw in ozone without using a pump, or by using a compressor instead of a pump to flow ozone while applying pressure. It is also possible to react more ozone with the sewage.

By arranging a heater for heating water before and after the water circulating pump 11, which is a circulating means, the present apparatus can be used as a "circulating hot water bath."

Further, in the second embodiment,
The timing at which the switching valve 3 is switched is managed by the timer 23 based on time. For example, a method of providing a flow rate sensor and managing the flow rate or a method of managing the turbidity of the wastewater using a turbidity sensor is used. It is also possible.
