The system is controlled so that the process discharge process proceeds sequentially.

The biowastewater storage process is a process of storing biowastewater before sterilization as shown in FIG. 16a. This is to receive bio-wastewater from a research facility or hospital, etc. through the bio-waste water transfer pipe 110 and temporarily store it in a storage tank, that is, the storage tank chamber 101 . At this time, in the present invention, the bio-waste water transfer pipe 110 is not only transferred through opening and closing using a valve as necessary, but also is always opened to continuously supply and store bio-wastewater. On the other hand, when the bio-wastewater is stored in the storage tank chamber 101 as described above, the pressure therein may increase. At this time, in the present invention, the internal air is discharged through the chamber sterilization filter 120, but when the Harmful components are filtered and discharged into the atmosphere in a sterilized state.

The bio-wastewater filling process is a process of receiving and filling the bio-wastewater stored in the storage tank 100 to the bio-kill tank 200 for sterilization as shown in FIG. 16B , preferably in the bio-kill tank chamber 201 . is charged At this time, as the charging method, the bio-waste water supply pipe 210 is opened, but the bio-waste water from the storage tank chamber 101 is supplied to the bio-kill tank chamber 201 through the opened bio-waste water supply pipe 210 . will be saved In addition, as described above, the pressure lowering pipe 300 for connecting the tank is opened together in the charging process, but it enables smooth supply through ventilation in the process of transferring the bio-wastewater. That is, in the bio-wastewater filling process, the bio-wastewater temporarily stored in the storage tank 100 is filled in a predetermined amount through the bio-wastewater supply pipe 210 .

The biowastewater preheating process is a process of preheating the biowastewater filled in the biokill tank 200 prior to sterilization, as shown in FIG. 16c . At this time, as the preheating method, the steam supply pipe 410 connected to the wastewater heating device 400 may be opened while the biowaste water supply pipe 210 is closed. The vapor is supplied to the bio kill tank jacket 202 of the bio kill tank 200 . Accordingly, the high-temperature steam supplied to the bio-kill tank jacket 202 heats the bio-kill tank chamber 201, and indirectly heats the bio-waste water charged in the bio-kill tank chamber 201, Preferably, the temperature of the biowastewater may be preheated to 90°C. And when the bio-wastewater is preheated as described above, air remains inside the bio-kill tank chamber 201, and at this time, the air is discharged through the open tank connection and pressure drop pipe 300 and the storage tank ( 100) will be returned. Meanwhile, in the present invention, when preheating the biowastewater as described above, the biowastewater can be stirred using the stirrer 230, and such agitation of the biowastewater enables even and rapid preheating of the biowastewater. The preheating efficiency can be further improved. That is, in the bio-wastewater preheating process, the bio-wastewater filled in the bio-kill tank 200 is preheated to a predetermined temperature and internal air is discharged to provide an optimal sterilization treatment environment prior to sterilization.

The biowastewater sterilization process is a process of sterilizing harmful components by performing main heating on the preheated biowastewater as shown in FIG. 16d.

It becomes possible, and heating efficiency can be improved further. That is, in the bio-wastewater sterilization process, the bio-wastewater is indirectly heated for a predetermined time in the closed state of the bio-kill tank chamber 201 to kill viruses and microorganisms present in the bio-wastewater.

The bio-wastewater cooling process is a process of cooling to a certain temperature before discharging the sterilized bio-wastewater in a state where the sterilization treatment of the bio-wastewater is completed, as shown in FIG. 16E . At this time, in order to cool the tank, first, the tank cooling pipe 500 is opened. As a result, the sealed state of the bio-kill tank chamber 201 is released and at the same time flash vapor and waste heat are instantaneously transferred to the tank cooling pipe 500 ) through the storage tank jacket 102 is discharged and recovered. Accordingly, the pressure inside the bio-kill tank chamber 201 is released and the bio-wastewater is cooled due to the discharge of heat. At this time, the flash vapor and waste heat discharged to the storage tank jacket 102 as described above are stored Since heat exchange with the biowastewater stored in the tank chamber 101 is performed, the biowastewater in the biokill tank chamber 201 may be pre-cooled to about 100° C. through this heat exchange. In addition, flash steam and waste heat discharged to the storage tank jacket 102 as described above are condensed through heat exchange with bio-waste water stored in the storage tank chamber 101 and stored as condensed water, while air and waste heat are stored in the jacket sterilization filter. It is filtered through 130 and safely discharged into the atmosphere. That is, in the bio-wastewater cooling process, the internal pressure of the bio-kill tank chamber 201 is relieved and flash steam and waste heat are recovered, thereby cooling the sterilized bio-wastewater. In particular, the waste heat is safely recovered and cooled and discharged. By doing so, it is possible to protect the jacket sterilization filter 130 by increasing the dryness of the atmospheric release gas and decreasing the pressure.

The bio-wastewater discharging process is a process of discharging the pre-cooled bio-wastewater as shown in FIG. 16F. In this case, in order to discharge the bio-wastewater, first, the bio-wastewater discharge pipe 220 may be opened, and the bio-wastewater sterilized therefor is discharged through the bio-wastewater discharge pipe 220 . And condensed water is generated in the storage tank jacket 102 that performs heat exchange between the flash vapor and waste heat recovered in the bio-waste water sterilization process. 220) will be joined. At this time, the bio-wastewater discharge pipe 220 is configured with a heat exchanger 600, and the bio-wastewater and condensed water discharged as described above are cooled to about 60° C. in the process of passing through the heat exchanger 600 and discharged to the outside. will become Meanwhile, in the present invention, cooling of the biowaste water using the heat exchanger 600 is enabled through indirect heat exchange using the cooling water charged in the heat exchanger 600 . That is, in the bio-wastewater discharging process, cooling through indirect cooling is performed in the process of discharging bio-wastewater as described above, thereby preventing an increase in fatigue level of the tank base material and water hammering.

Even if this embodiment is applied, it is possible to effectively treat bio wastewater with a high risk of propagation of active viruses, microorganisms, or bacteria, thereby protecting the environment and contributing to profit creation by replacing foreign equipment. and can provide an optimized maintenance environment.
