A central control system and method of the present invention.

In the central control system and method of a dieal reactor according to the present invention, the detection data of the performance state of each diene reactor process and the operation state of each process facility are detected from sensors installed in each process facility constituting the diene reactor. Receives a signal, monitors the performance of each process of the diene reactor from the detection data, monitors the operating state of each process equipment of the diene reactor from the detection signal, and monitors the It displays the execution status and operation status of each process equipment, and controls the operation status of die reaction reactor process equipment according to the monitoring result to control the execution status of die reaction reactor process under the optimal conditions at the remote control center. It provides a central control system and method of the diene reactor.

Daewoo Nutrients Removal (DNR) is based on the principle of nitrogen and phosphorus treatment, and consists of four processes: sludge denitrification tank, anaerobic tank, anaerobic tank and aeration tank.

The sludge denitrification tank removes nitrate nitrogen in the return sludge, the anaerobic tank releases phosphorus of microorganisms, and the aeration tank absorbs and removes the phosphorus released from the anaerobic tank, and the anoxic tank removes the nitrified mixture from the aeration tank. After receiving and denitrifying, nitrogen gas is removed.

Each process performed in each process equipment of the diene reactor is as follows.

1) Sludge Denitrification Process

The sludge denitrification tank is a facility for preventing phosphorus release from being prevented in the anaerobic tank due to nitrate nitrogen in the return sludge. The sludge denitrification tank removes nitrate nitrogen by endogenous denitrification. The process is carried out with an endogenous denitrification coefficient of 0.01-0.08 mgNO ₃ / mgMa / d and a microbial concentration of 6,000-10,000 mg / l for a residence time of 20-30 minutes, based on the influent sewage of the sludge denitrification tank.

2) anaerobic process

Anaerobic process is a facility for removing excess phosphorus by forming anaerobic conditions in order to remove phosphorus biologically and releasing phosphorus in excess amount necessary for the growth of microorganisms in the aeration tank. The anaerobic tank checks the concentration of influent organics and designs a shorter residence time as the concentration is lower, with an average residence time of 1.0-1.5 hours. In addition, the anaerobic tank is operated so that the ORP (Oxidation-Reduction Potential) is -350 to -150 mV, and the chemical oxygen demand (COD) consumed during phosphorus release is maintained to maintain 3 gRBD COD / g Prel. do.

3) Anaerobic Digestion Process

An anoxic tank is a facility that forms anoxic conditions in order to remove nitrogen biologically, denitrates nitric nitrate nitrogen from the aeration tank, and removes it with nitrogen gas. The anaerobic tank has an internal transfer rate of 100-200% within the operating ORP -200-0mV for a residence time of 1.0-2.0 hours.

4) Abandonment

Nitrifying ammonia nitrogen and returning it to an anaerobic tank, oxidizing and removing unremoved organic matter, and removing excess phosphorus from anaerobic tank. The aeration tank maintains the MLSS (Mixed Liquor Suspended) concentration at 2,000-3,000 mg / l while maintaining DO (Dissolved Oxygen) at 1.0-3.0 mg / l for 3.0-4.0 hours of residence. do.

The characteristics of the diene process method is a pure biological treatment method without the addition of chemicals, the facility cost and operation maintenance costs are low, and the operating method of the standard activated sludge method can be sufficiently maintained with the existing operation technology. In particular, it is suitable for domestic sewage, so it can be applied immediately to domestic low concentration sewage, 90% of BOD (Biochemical Oxygen Demand), 75% of TN (Total Nitrogen) and TP (Total Phosphorus) 85% of) is removed and the processing efficiency is very good.

In addition, the conveying sludge treatment process by the DNL method is a single internal circulation facility, which makes the facility simpler to maintain and maintains, and it is possible to secure stable nitrogen and phosphorus microorganisms by continuously supplying sludge through the conveying sludge. Nitrogen-resistant nitrogen is endogenously denitrified in the sludge denitrification tank to remove the phosphorus release inhibition caused by nitrate nitrogen in the next anaerobic tank.

Each of the process equipments of the diene reactor is set for each operation standard suitable for each process, and in order to perform an efficient process according to the operation criteria, the operation state of each process and the operation state of each process equipment are continuously Monitoring and confirmation of abnormalities should be made.

However, since each process is organically related and each process equipment is composed of circulating facilities throughout the diene reactor, integrated control of the diene reactor is difficult, and when an abnormality occurs in the diene reactor, There is a problem that is very difficult to determine what process equipment occurred and what abnormalities occurred.

In particular, when an error occurs in the overall process, there is a problem that can not be detected immediately, and to control the process equipment in which the error occurs in response to the occurrence of an error to recover the normal operating state in a short time.

Accordingly, an object of the present invention for solving the above problems is to provide a central control system and method of a dieal reaction tank that can be managed and controlled by integrating the operation state and operation state of the die reaction reactor as a whole.

Another object of the present invention is a central control system of a dieal reactor to detect a failure in the dieal reaction tank immediately, and to recover the normal operating state in a short time by controlling the process equipment in response to the occurrence of the failure And providing a method.

It is still another object of the present invention to provide a central control system and method of a dieal reactor that can monitor, manage and control the diene reactor in a remote central control center.
