The M ₂ LE process described below is defined as a process in which a membrane is installed instead of a settling tank at the downstream end of a reaction vessel in a conventional MLE process.

Most existing small-scale sewage treatment facilities are located in upstream areas of rivers, so effluent flows into the upstream of rivers or water sources. Therefore, more efficient treatment is important. In addition, the area where the small-scale sewage treatment facility is located is mostly a rural unit, and the change of the sewage generation load during the day is significant, and the seasonal change is known to be severe compared with the sewage treatment plant.

Moreover, the small-scale sewage treatment facility is operated by unmanned operation, which makes maintenance difficult. As a result, there is a problem in maintaining proper efficiency due to not being actively operated on the load fluctuation, and energy loss is occurring in each treatment plant due to the fact that the operation suitable for the load fluctuation is not performed. This has caused a considerable energy loss when considered nationally. Many techniques have been developed to solve this problem. However, researches on maintenance aspects and low cost driving methods have been somewhat lacking.

Collecting and storing data measured by the measuring device in a data collector and graphically displaying a change in an ORP value in real time;
The automatic control unit receives the measurement data from the data collecting unit and controls the oxygen injecting unit for injecting oxygen into the aerobic tank of the M ₂ LE reaction tank, and calculates an optimum coagulant amount based on the input data of the appropriate amount of coagulant Forming a control signal for controlling the coagulant infusion pump so that an appropriate amount of coagulant per phosphorus concentration is injected into the M ₂ LE reactor; And
Receiving transmitting the control signal and to inject the oxygen into the oxygen injected additional aerobic tank of the M ₂ LE reaction tank, the M ₂ LE tank and the coagulant flocculant injected into the pump is running appropriate coagulant dosage is the M ₂ LE reaction tank is provided between the reservoir , The method comprising:
In the step of introducing, the automatic control unit operates the inflow water supply pump so that the inflow water flows into the anaerobic tank of the M ₂ LE reactor,
In the denitrification step, the automatic control unit drives the mixer driving unit to stir the influent water flowing into the anoxic tank. When the automatic control unit reaches the downward saturation based on the ORP value change graph, it is determined that the denitrification is completed When the denitrification is completed, the automatic control unit stops the operation of the mixer driving unit, operates the oxygen supply pump to inject oxygen into the aerobic tank,
Wherein the well-oxidizing step is performed such that, in a state where oxygen is injected into the oxic tank, when the automatic control unit reaches the upper saturation based on the ORP value change graph, it is determined that the nitrification is completed and the operation of the oxygen supply pump is stopped The process water discharge pump is operated,
In the step of forming the control signal
Characterized in that, after the nitrogen removal is completed, the automatic control unit determines the appropriate amount of coagulant injected based on the phosphorus concentration correlation data for the electric conductivity concentration and the coagulant injection amount data for the phosphorus concentration, Conductivity - based Phosphorus Removal Automatic Control M ₂ LE Advanced Processing System. delete delete delete
