Description

Management system of septic tank aeration apparatus { Management system of aeration apparatus for septic tank }

The present invention relates to a management system for a septic tank aeration device, and in particular, to a management system for a septic tank aeration device that can easily determine whether or not an aeration device connected to a septic tank is broken and quickly take follow-up measures.

As modern society becomes industrialized and industrialized, the amount and degree of pollution of wastewater discharged from homes or industrial sites are gradually increasing. Accordingly, a considerable number of conventional technologies for methods and facilities for treating wastewater have been developed. there is.

In general, the methods commonly used to treat sewage and wastewater include chemical treatment and biological treatment.

The chemical treatment method is fast, but there is a problem of additional contamination by chemicals, so the biological treatment method is widely used, and among them, the activated sludge method is being actively studied.

The activated sludge method is to aerate and stir wastewater together with activated sludge (aerobic bacteria) in an aeration tank to almost satisfy BOD (biological oxygen demand). When the colloidal phase or dissolved substances in the sewage precipitate or adhere to the activated sludge, it becomes clean water. It refers to a method of treating wastewater by separating the precipitated substances after a single purification process, discarding them as necessary, or returning them to the main treatment process. Recently, mergers have been conducted by merging and treating wastewater generated from homes or industrial sites. Septic tanks are widely used.

Conventional wastewater combined purification tanks generally consist of a flow control tank, multiple aeration tanks, and sedimentation tanks.

When wastewater flows into the sewage inlet through the wastewater pipe installed within the building, it flows into the flow adjustment tank.

Sewage that flows excessively into the flow rate adjustment tank at one time is adjusted to an appropriate amount of sewage through a flow rate adjustment pump and flows into the aeration tank.

The air supplied from the aeration device dissolves into the water in the form of bubbles and increases the concentration of dissolved oxygen, helping the respiration of microorganisms living in the aeration tank.

Therefore, in the aeration tank, aerobic microorganisms that feed on contaminants in the sewage and consume oxygen supplied through the aeration device grow.

As they pass through various stages of aeration tanks, the microorganisms grow and clump together to form flocs, which flow into the sedimentation tank. The flocs settle to the bottom of the sedimentation tank, and the supernatant overflows the weir and is discharged to the outlet.

And the floc settled at the bottom of the sedimentation tank is returned in the form of sludge to the first aeration tank through the sludge return pump to maintain an appropriate amount of microorganisms in the aeration tank and continuously treat the incoming sewage.

For the smooth operation of such wastewater combined septic tanks, the most important thing is to decompose and purify organic matter contained in sewage and wastewater by microorganisms. To this end, an aeration device to increase the amount of dissolved oxygen must be provided.

The aeration device is generally implemented by an air supply pump installed outside the septic tank.

The aeration device consists of an air supply pump, a control panel for controlling the air supply pump, an external air intake and supply port connected to the air supply pump, and a case for accommodating them.

When sewage treatment facilities, including septic tanks, are located in remote locations, technology has recently been developed to check and manage the status of sewage treatment facilities located in remote locations in real time.

However, the conventional septic tank aeration device management system can only perform simple monitoring, and has limitations in easily determining whether the aeration device is malfunctioning and taking follow-up measures.

When only the first aerator 21 is operated while the second aerator 22 is stopped, the air supplied from the first aerator 21 is supplied through the bypass pipe 70 and the second air. It moves through the flow pipe 32, and at this time, the flow amount of air supplied from the first aeration device 21 is measured by the second sensor 42 mounted on the second air flow pipe 32.

If the measured value measured by the second sensor 42 deviates from a preset constant value, the control unit 50 determines that the first aerator 21 is malfunctioning, and the measured value measured by the second sensor 42 If the measured value is within a preset certain value range, the control unit 50 determines that the first sensor 41 is defective.

Through this, if the measured value from the first sensor 41 deviates from a preset constant value, it is accurately determined whether the aeration device or the sensor is malfunctioned, and the malfunctioning part is quickly and accurately replaced or repaired. can do.
