The present invention relates to an energy-saving wastewater treatment system, and more particularly, to an energy-saving wastewater treatment system in which energy efficiency is remarkably increased by efficiently controlling a system based on various data measured in wastewater treatment.

Sewage contains a lot of pollutants and a method to remove it is required. In recent years, the emission standards of biochemical oxygen demand (BOD), phosphorus (P), and nitrogen (N) of discharged water finally discharged from a sewage terminal treatment plant become more stringent.

Generally, the altitude treatment consists of the initial settling basin where the sewage flows, the bioreactor that removes the nitrogen, phosphorus, etc. contained in the sewage, and the final settling basin that is settled secondarily. In order to satisfy the discharge standard of discharged water, MLDO, Mixed Liquor Dissolved Oxygen) was measured and the blower was operated in proportion to the measured value.

However, the amount of dissolved oxygen in the bioreactor fluctuates due to the external environment such as water temperature, so that the blowing amount can not be controlled based on this.

In general, the bioreactor is equipped with an ammonia meter to adjust the ammonia concentration to a minimum. However, since the MLSS (mixed liquor suspended solid) is very high in the bioreactor, the ammonia concentration can not be accurately measured , There is a problem that a separate cleaning device must be provided in the ammonia measuring instrument.

Accordingly, a system has been developed that measures the ammonia concentration of the discharged water and adjusts the operation rate of the blower and the internal return pump to stably manage the quality of the discharged water.

As a result of various methods for solving the above-mentioned problems, the inventors of the present invention have developed a control system to control the blower through a separate ammonia concentration meter for discharged water to reduce energy and to control the ammonia concentration meter and the blower in a mutually stable manner , And developed an energy-saving wastewater treatment system that can stably manage the quality of wastewater discharged from the wastewater treatment plant.

FIG. 1 schematically illustrates the energy-saving wastewater treatment system, and FIG. 2 schematically illustrates one embodiment of the energy-saving wastewater treatment system.

The present invention will be further described below with reference to Figs. 1 and 2.

The energy-saving wastewater treatment system includes a wastewater inlet 10, a first precipitator 20, a bioreactor 30, a second precipitator 40, a filtration unit 50, and a discharge unit 60, And the wastewater flowing through the wastewater inflow section 10 is discharged through the discharge section 60 through the respective processing steps. At this time, the measuring device installed at a specific position collects various data about the wastewater in process, and the controller 70 efficiently and stably supplies the blower 33 and the internal return pump 34 based on the collected data. So that the energy can be reduced.

As described above, the wastewater flows into the wastewater inflow section 10 through which the wastewater flows into the wastewater inflow section 10, and the wastewater inflow section 10 can include the flow meter 13.

The wastewater inflow section 10 may include a gill clam 11 and may be a stone, sand or the like having a specific gravity larger than that of the gill 11 and having a small specific gravity, . In addition, the wastewater inlet 10 may include a pump station 12 to allow incoming wastewater to undergo further processing steps.

Since the wastewater inlet 10 includes the flow meter 13, the flow meter 13 measures the amount of incoming wastewater in real time, and the measured data is sent to the controller 70.

The flow meter 13 refers to a meter for measuring the amount (volume or mass) of a gas or liquid flowing in a unit time. The meter 13 includes a differential pressure meter 13, a laminar flow meter 13, an amperometric meter 13, At least one selected from the group consisting of a flow meter 13, a turbine flow meter 13, an electronic flow meter 13, an ultrasonic flow meter 13, a thermal type flow meter 13, and a Karman vortex flow meter 13 It is not.

The wastewater discharged from the wastewater inflow section 10 from which sediment and solids have been removed may be introduced into the first settling section 20, which processes the inflowed wastewater by gravity settling.

The first settling unit 20 collectively refers to the first settling tank 21 through which the wastewater flows first in a conventional sewage treatment facility. The floating material contained in the wastewater is discharged by gravity to be removed, And serves as a pretreatment facility in the subsequent continuous wastewater treatment.

The precipitate settled in the first settling portion is called raw sludge, and the raw sludge can be mixed with the excess sludge concentrated in the mixed storage tank and can be extinguished.

The biological reaction unit 30 biologically processes the wastewater pretreated in the first settling unit. The biological reaction unit 30 may include an anoxic tank 31 and an oxic tank 32 in order and may include an internal transfer pump 34, a blower 33, and a dissolved oxygen meter 36.

The bioreactor 30 may be configured to rapidly supply aerobic microorganisms by supplying air and oxidize and decompose organic substances contained in the sewage by the metabolism of the microorganisms to remove fine contaminants and odors .

As described above, the bioreactor 30 may include a general bioreactor including an anoxic tank 31 and an oxic tank 32 in sequence. At this time, the anoxic tank, the aerobic tank, the anaerobic tank, the membrane separation aerobic tank, etc. may be arranged in the biological reactor according to the method.

The anoxic tank 31 is nitrogen denitrifying bacteria (e.g., Pseudomonas, Micrococcus, Spirillum, Acaligenes, Bacillus, etc.) via the N ₂ O, the form of NO by nitrate respiration, nitrite respiration is reduced to N ₂ can be released have. The anoxic tank 31 may be equipped with an underwater stirrer to sufficiently mix the inflow wastewater and the transported object and to prevent solid-liquid separation.

The aerobic tank 32 can generate nitrate (NO ₃ ) by decomposing ammonia nitrogen (NH ₄ -N) by metabolism of aerobic microorganisms. The aerobic tank 32 needs to be supplied with oxygen necessary for oxidation of organic matter required for assimilation of activated sludge microorganisms. Therefore, the oxic tank 32 may be provided with a blower 33 for supplying air through a pipe. In addition, an inverter may be installed in the blower 33 so that the operating rate of the blower 33 can be adjusted by varying the frequency.

In addition, the biological reaction unit 30 may include a dissolved oxygen meter 36 and an internal transfer pump 34 in the exhalation unit. The inner transfer pump 34 serves to transfer the activated sludge from the aerobic tank 32 to the anoxic tank 31 and the activated sludge is transported through the inner transfer line 35 connected to the inner transfer pump 34 .

The inner conveyance line 35 connects the anoxic tank 31 at the front end and the oxic tank 32 at the rear end and the activated sludge of the oxic tank 32 is conveyed to the anoxic tank 31 through the inner return line 35 .

Then, the wastewater passing through the bio-reaction unit 30 may be introduced into the second settling unit 40. The sludge formed in the bioreactor 30 flows into the second settling unit 40 to perform secondary treatment through gravity settling, and is generally referred to as a final settling tank 41. At this time, some of the sludge settled in the second settling unit 40 is transferred to the sludge disposal process, and some of the sludge is transferred to the front end of the bioreactor to supplement the amount of microorganisms. Subsequently, the secondary treated water of the second settling unit 40 can be discharged through the discharge unit 60.

The discharge unit 60 may include a treatment water tank 61 that sterilizes the wastewater treated secondarily in the second deposition unit 40 and stores the discharged wastewater so that the discharge concentration can be measured, If it meets the criteria, it will be discharged. The discharge unit 60 may include a water quality remote monitoring system 62 for measuring various water quality indicators such as ammonia concentration and total nitrogen concentration TN of the treated water and an ammonia concentration meter 63.

The water quality remote monitoring system 62 is configured to monitor the pH of the effluent water, the biochemical oxygen demand (BOD), the chemical oxygen demand (COD), the suspended solids (SS), the total nitrogen (TN) by measuring and the like, and transmits the measured value to the controller 70, the ammonia concentration of the instrument 63 sends out a measured value of the ammonia concentration of (NH ₄ -N), a control unit 70.

The ammonia measuring instrument is disposed in the discharge portion 60 to measure the ammonia concentration of discharged water having a relatively low suspended solids, and a conventional washing apparatus is not required. The ammonia meter may be an electrode type meter capable of measuring the ammonia concentration in real time. However, the ammonia meter may be an integrated meter capable of calculating various measured values such as total nitrogen concentration as well as ammonia meter .

At this time, the energy-saving wastewater treatment system may further include a filtration unit 50 for filtering the solid matter of the wastewater that has been gravity-settled in the second settling unit 40 at the rear stage of the second settling unit 40 have.

The filtration unit 50 includes a filter paper 51 for filtering solid matter in the wastewater treated in the second settling unit 40 and can perform total phosphorus treatment together.

That is, in the case of a conventional wastewater treatment system, a single variable such as a method of controlling the blower 33 based on the dissolved oxygen measurement value of the reaction tank or controlling the blower 33 based on the measured ammonia concentration value of the discharged water It is impossible to flexibly cope with various parameters according to each unexpected situation.

Therefore, the control unit 70 receives data from the flow meter 13, the dissolved oxygen meter 36, the ammonia concentration meter 63, and the water quality remote monitoring system 62 in real time, (33) and the internal return pump (34).

The control unit 70 may include a computer 71 and a computer-like processing device for receiving and analyzing the measured data. The computer 71 refers to a high-speed automatic calculator using electronic circuits, and collectively refers to a device capable of performing calculations widely used in numerical calculation, automatic control, data processing, office management, language, and image information processing.

Energy saving type Wastewater  Processing system control method

Another aspect of the present invention is to provide an energy-saving wastewater treatment system control method for automatically controlling a treatment facility through a measurement value of a measurement facility, the method comprising: when the inflow flow value measured by the wastewater inflow section 10 exceeds a predetermined value , A warning message is transmitted to the user or the blower 33 of the biological reaction unit 30 is operated at a predetermined capacity

The present invention also provides an energy-saving wastewater treatment system control method for automatically controlling a treatment facility through a measurement value of a measurement facility, wherein when the ammonia concentration meter 63 fails to measure the ammonia concentration, And controlling the operation of the blower (33) based on the ammonia concentration measurement value for a predetermined period stored in the data storage unit (100).

The energy-saving wastewater treatment system controls and manages the blower 33 in the same manner as in the conventional operation.

Here, the normal operation state refers to a normal operation state in which there is no special variation or variable in operation of the system.

That is, the control unit 70 receives the ammonia concentration information from the ammonia concentration meter 63 located in the discharge unit 60 at predetermined intervals, and controls the operation rate of the blower 33 through the measured ammonia concentration . Here, the ammonia concentration may be an average value of the ammonia concentration measured at a predetermined interval, or the ammonia concentration measurement value may be sent to the controller 70 in real time.

At this time, if the blowing amount is increased in the zone where the ammonia concentration measured by the discharge unit 60 is increased, the ammonia concentration of the discharged water is decreased. When the blowing amount is increased, the supply of air to the aerobic tank 32 increases, So that the concentration of ammonia is relatively reduced.

According to one embodiment, when the measured ammonia concentration exceeds 2.5 mg / L, the operating rate of the blower 33 is increased. Generally, the BOD reference value of the discharged water is about 10 mg / L, the reference value of the total nitrogen concentration of the discharged water is about 20 mg / L, and when the ammonia concentration of the discharged water exceeds 2.5 mg / L, the BOD of the discharged water and the total nitrogen concentration become close to the above- do. Therefore, when the blowing amount of the blower 33 is adjusted to maintain the ammonia concentration of the discharged water at 2.5 mg / L or less, the BOD of the discharged water and the total nitrogen concentration can be kept below the reference value. If the measured ammonia concentration is less than 0.8 mg / L, the operating rate of the blower 33 can be reduced. When the ammonia concentration is less than 0.8 mg / L, the BOD of the discharged water and the total nitrogen concentration are kept below the reference value, so it is not desirable from the viewpoint of energy efficiency to keep the blower 33 operating continuously.

FIG. 3 is a graph showing a method of controlling the amount of air blowing according to the ammonia concentration measurement value of the discharged water, and the embodiment can be more easily understood.

When the blower 33 includes an inverter, the controller 70 may control the operation rate of the blower 33 by controlling the drive frequency (Hz) of the inverter interlocked or manually. When a plurality of blowers 33 are installed in the oxic tank 32, the air supply amount can be adjusted by adjusting the entire or at least one blower 33.

However, unlike the above, the energy-saving wastewater treatment system can be operated under abnormal conditions such as power failure, heavy rain, etc. in addition to normal normal operation.

First, when a sudden power failure situation occurs to the treatment plant, the energy-saving wastewater treatment system supplies electric power through the emergency generator, and the blower 33 can operate normally. However, when the ammonia concentration meter 63 is reactivated after the power failure, the ammonia concentration value is not measured during the non-operating time, and therefore there is no measurement value for controlling the blower 33. [ Therefore, the controller 70 averages the concentration of ammonia detected immediately before the power failure to automatically determine the optimum air flow rate of the blower 33.

In one embodiment, the detected ammonia concentration average value is determined by averaging past ammonia concentration values, and the driver can preferably be set to automatically calculate the concentration average value for each time period within the range of 1 to 7 days. Even when the ammonia concentration is easily varied by various variables around the blower 33, the blower 33 can be operated stably because the air volume and the concentration value of the blower 33 converge to an optimum point after a certain time passes

The control unit 70 may include a data storage device for storing the calculated ammonia concentration average value and controlling the blower 33 through the stored ammonia concentration average value as described above.

The type of the data storage device is not particularly limited, and a commonly used hard disk, flash memory, or the like can be used.

The system operation under the power failure state can be applied not only to a power failure situation but also to a similar situation. For example, when the energy-saving wastewater treatment system is switched to manual operation for replacement of the blower 33 or various measuring instruments, when the equipment is replaced and operated again in the automatic operation mode, (33) can be controlled.

In addition, when an abnormal condition (for example, pipe clogging, malfunction, breakage or the like) occurs with respect to the ammonia concentration meter 63, the controller 70 detects an abnormal condition of the ammonia concentration meter 63, And the optimum air volume of the blower 33 is automatically determined by averaging the measured ammonia concentration immediately before the detection of the abnormal condition in the same manner as described above.

Therefore, as described above, the energy-saving wastewater treatment system may further include a message transmission unit 80 for transmitting a warning message when a predetermined result value is calculated based on the received measurement data.

Next, the wastewater treatment facility is designed with the maximum flow rate for each unit process, and the pump is designed for the maximum flow rate after the biological treatment process

However, in the event of sudden rainfall, large amounts of organic matter and solids concentration can be rapidly increased in a pattern such as flow rate as groundwater, river water, and stormwater are introduced.

Typically, the initial flow pattern represents the maximum flow rate within about 3 hours of the initial rainfall, and if the blower 33 is controlled through the ammonia concentration measurement of the discharged water during the operation of the bioreactor, an impact load is generated in the bioreactor, It can be difficult.

In order to solve the above problem, the flow meter 13 provided in the wastewater inlet 10 measures the flow rate in real time and sends it to the controller 70. The controller 70 calculates the flow rate The blower 33 can be controlled according to the operation of the blower.

In one embodiment, when the inflow flow value received by the controller 70 exceeds a maximum flow rate, the message transmission unit firstly transmits a warning message to the user. When the inflow flow rate value exceeds the maximum flow rate after a predetermined time elapses, (33) can be set to operate at the designed capacity or the predetermined capacity of the blower (33) regardless of the ammonia concentration measurement value.

The controller 70 compares the total nitrogen concentration measured value received from the water quality remote monitoring system 62 with the estimated total nitrogen concentration estimated from the measured ammonia concentration to determine whether or not the denitrification is bad, The operating rate of the internal return pump 34 can be controlled.

In one embodiment, the controller 70 may calculate the total nitrogen concentration predicted value of the discharged water based on the measured ammonia concentration value of the discharged water. Since the ammonia concentration has a constant correlation with the total nitrogen concentration, it is easy to predict the total nitrogen concentration when such correlation is used. In this case, if the calculated total nitrogen concentration value is larger than the estimated total nitrogen concentration by 2 mg / L or more, it can be judged that the denitrification is bad.

In general, the total nitrogen concentration of the discharged water takes a long time to analyze, while the ammonia meter according to the present invention can be constructed in an electrode-type so that the ammonia concentration can be measured in real time. Therefore, the estimated total nitrogen concentration is calculated based on the ammonia concentration measured in real time, and compared with the total nitrogen concentration, it becomes possible to manage the total nitrogen concentration immediately. That is, when the measured total nitrogen concentration is greater than the estimated total nitrogen concentration, it can be judged that the nitrified activated sludge is not sufficiently denitrified in the anoxic tank 31.

The control unit 70 increases the operation rate of the internal transfer pump 34 connected between the anoxic tank 31 and the oxic tank 32 to circulate the increased internal transfer amount to the anoxic tank 31 The denitrification process can be performed again.

Accordingly, the energy-saving wastewater treatment system automatically compares the estimated total nitrogen concentration with the total nitrogen concentration and the measured ammonia concentration, and operates the power of the internal return pump 34 under proper conditions according to the legal water quality standard, Consumption can be prevented. When comparing the total nitrogen concentration estimated through the total nitrogen concentration and the ammonia concentration measured value, if the comparison value exceeds the predetermined value, it is recognized as an abnormal condition, and the message transmission unit 80 transmits a warning message to the user .

In addition, the controller 70 can automatically estimate the nitrification reaction rate and the nitrification efficiency value according to the temperature change based on the atmospheric and water temperature values and the MLSS concentration of the bioreactor. In general, when the water temperature decreases to below 13 ℃, the reaction rate of nitrifying bacteria decreases sharply. Therefore, it is possible to indirectly confirm the state of nitrification at all times as the starting point temperature. The rate of nitrification and the efficiency of nitrification according to the temperature can be calculated by referring to the correlation formula with the temperature specified in the detailed design report derived from each site design.

The energy-saving wastewater treatment system may further include a power measurement unit (not shown) for measuring the amount of power used by the internal return pump 34 and the blower 33, which are controlled based on the received measurement data .

In an embodiment, the power measuring unit (not shown) measures the power consumption of the blower 33 and the internal return pump 34 installed in the energy-saving wastewater treatment system in real time, Time, day, month, and year.

The energy-saving wastewater treatment system may further include a display unit 90 for outputting various data including a value calculated by the power measurement unit (not shown).

Therefore, the display unit 90 displays various data such as the ammonia concentration of the discharged water, the total nitrogen concentration of the discharged water, the estimated total nitrogen concentration of the discharged water, the operating rate of the blower 33, the operating rate of the internal return pump 34, And can be confirmed by the user through an output means such as a monitor.

It will be understood by those skilled in the art that the foregoing description of the present invention is for illustrative purposes only and that those of ordinary skill in the art can readily understand that various changes and modifications may be made without departing from the spirit or essential characteristics of the present invention. will be. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
