Exhaust systems that are currently commercialized in a continuous batch reactor are complicated in structure or require power for control, and include an air vent type exhaust system, a diaphragm type exhaust system and a female type exhaust system, And a discharging device which is used is adopted.

The air vent type discharge apparatus is applied as a basic principle of operation in most apparatuses and is operated by solenoid valve opening and closing for control of the apparatus so that a separate actuator and a power supply facility are additionally required in addition to the operation of the wastewater treatment apparatus There is a problem of economic burden.

In addition, the female-type discharging device operated by the power device is operated so that the discharging device descends to the limit depth at the speed set by the power device at the discharging process in such a manner that the discharging device is discharged to the inside and outside of the reaction tank and the supersonic water is discharged There is a problem that it is costly economically due to a complicated driving method and a high cost. It does not provide a driver-oriented operating system as devices that do not meet the requirements for the understanding of the operating status of the supercritical water discharge and the easy exhaust structure.

The discharge device using hydraulic pressure has also been developed to flow up and down mechanically. This is because the efficiency of the treatment is high, but the manufacturing cost and the excessive power ratio during operation are problematic and various automatic mechanisms are operated. And there is a problem that it is impossible to install it in a small-scale wastewater treatment plant because the facility is particularly large.

Also, as disclosed in Korean Patent Laid-Open No. 2010-0011622, since the lower portion of the decanter has a flat plate shape, it is difficult to keep the decanter horizontal due to swirling and twisting due to agitation and swelling, This causes frequent occurrence of short product life and shortage of the product, as well as scum generated during processing of wastewater due to the flow of decanter, and the center of gravity of the decanter is lost due to buoyancy and gravity, There is a problem that the discharge water becomes turbid because the inflow channel is formed obliquely with the reaction tank and the inflow pipe deposit generated in the initial discharge process is adhered to the wall surface and is discharged.

Also, in the past, a high-water discharge device and a disinfection facility were installed separately.

As shown in FIG. 1, the conventional disinfecting system provides a UV sewage disinfection system using ultraviolet rays and fine bubbles excellent in disinfection ability and purification ability of sewage. However, And a driving chain are required, and there is no economical efficiency due to the complicated structure of the air vent.

Therefore, there has been a demand for a discharge system that is easy to structure and operate, is economical, has little trouble, can easily observe a normal discharge state even in an emergency, and discharges sterilized treated water stably and is easy to maintain.

In addition, the present invention is also characterized in that the inflow passages 103 are installed perpendicularly to the water surface and not the slope of the supernatant, so that microorganisms are prevented from being deposited in the inflow passages 103 during the aeration step after the aeration, It is possible to prevent the turbidity of the drain water which may occur in the process of discharging the supersonic water.

In addition, the present invention is characterized in that a position sensor is attached to a certain portion of the supersonic water discharge device, and when the supersonic water discharge device deviates from a preset position range on the supersonic water surface, the user is informed, By keeping the height above the water surface constant, it is possible to increase the discharge efficiency of the supernatant.

That is, when the supersonic water discharge device deviates from the preset range of the upper water surface, the notification module according to the present invention can send an automatic message through the automatic notification module when a malfunction occurs.

For this purpose, a basic alarm is set (S101), a condition is changed (S102), an alarm is sent according to the condition (S104), and a normal alarm (S103).

Here, the alarm according to the condition can be contacted to the second and third administrators in turn, for example, when the manager who is the first alarm target is absent or does not contact within a predetermined time, Instead of simply receiving the alarms in turn, change them so that you can control the method and process.

For example, the alarm content displays detailed information on which of the hybrid high-water discharge apparatuses having a plurality of disinfection facilities has failed.

In particular, when the number of times the alarm is sounded is equal to or greater than a predetermined value, the alarm can be controlled to be stopped (S105, S106).

At this time, it is possible to adjust the maximum number of alarms to be constant by reflecting personal information such as schedule of the second and third administrators. In other words, in the case of the second or third manager's leave, the number of alarms can be eliminated, and the number of alarms can be adjusted to a predetermined value or less when the working time has passed.
