Description

Real-time influent toxicity monitoring system and its operating method {REAL-TIME TOXICTIY MONITORING SYSTEM AND METHOD FOR OPERATING THE SAME}

The present invention relates to a real-time influent toxicity monitoring system and its operating method. More specifically, a real-time influent toxicity monitoring system equipped with an integrated eco-toxicity monitoring module and an automatic water sampling analysis unit to more accurately analyze the toxicity monitoring of influent water in real time. It relates to the system and its operating method.

Although facilities to treat sewage and wastewater have been installed and operated to improve water quality and protect the ecosystem, there is a problem in that hazardous chemicals cannot be completely removed through biological or physical or chemical treatment processes. Accordingly, hazardous chemicals that are not removed during the treatment of sewage and wastewater are discharged into public waters, adversely affecting the ecosystem and health.

In general, for environmental analysis, toxic substances have been quantitatively analyzed by applying physicochemical analysis techniques. However, physical and chemical analysis techniques are realistically impossible to analyze a wide measurement area in terms of cost, time, technology, and manpower required for analysis. Accordingly, ecotoxicity assessment analysis technology is emerging as a scientific and efficient management method for environmental analysis.

Ecotoxicity assessment analysis technology is a technology that uses living organisms to evaluate the hazards of substances existing in the environment. This technology can obtain information about the damage that may occur when the heterogeneous substances used are concentrated in living organisms or the bioavailability that may occur when various compounds coexist.

Types of ecotoxicity monitoring devices that use living organisms are generally classified according to the type of organism, and the components of the device change accordingly. Using various organisms (aerobic microorganisms, nitrifying microorganisms, sulfur-oxidizing microorganisms, luminescent microorganisms, algae such as half-moon, etc.), the growth rate, respiration rate, and luminescence of organisms that react to external pollutants are measured.

Meanwhile, the degree of reactivity to chemicals varies depending on the organism. For example, the reactivity to copper ions is highest in Daphnia, and gradually decreases in that order: microalgae, sulfated bacteria, and luminescent bacteria. In addition, the reactivity to cyan ions is highest in microalgae, and gradually decreases in that order: daphnia or sulfated bacteria, and luminescent bacteria. In addition, the reactivity to residual chlorine is highest in luminescent bacteria or sulfating bacteria, and gradually decreases in that order of microalgae and Daphnia. In addition, the reactivity to pesticides is highest in luminescent bacteria, and gradually decreases in that order: daphnia or sulfated bacteria, and microalgae.

In this way, ecotoxicity monitoring devices using living organisms show different reactivity to chemicals depending on the living organism, but conventional ecotoxicity sensing devices measure ecotoxicity values using one species among various living organisms, so they can affect the effects of various toxic substances. There was a limitation in that it could not be accurately estimated.

Additionally, the eco-toxicity monitoring device has a problem in that it cannot accurately analyze the chemical composition of the sample water being analyzed.

Therefore, there is a need for various research and development on the real-time influent toxicity monitoring system and its operating method to more accurately and quickly analyze the toxicity monitoring of sample water.

As shown in FIGS. 1 to 7, the real-time influent toxicity monitoring system 1000 is configured to monitor in real time whether toxic substances are contained in raw water flowing in through the influent water supply unit 10 from, for example, a sewage treatment plant or wastewater treatment plant.

This real-time influent toxicity monitoring system (1000) includes a raw water tank unit (2000), a raw water filter unit (3000), a sample water storage unit (4000), a water collection storage unit (5000), an integrated ecotoxicity monitoring module (6000), and an automatic It may include a water collection analysis unit 7000.

Here, the raw water tank unit 2000 is configured to accommodate raw water supplied from the inflow water supply unit 10. This raw water tank unit 2000 is connected to the influent water supply unit 10, and raw water to be measured for toxicity monitoring can continuously flow from the influent water supply unit 10. While the raw water tank 2000 is filled with a certain amount of raw water, the raw water in the raw water tank 2000 overflows due to the raw water continuously supplied, and the raw water tank 2000 is supplied from the inflow water supply unit 10. New enemies are constantly being filled. Therefore, the real-time influent toxicity monitoring system 1000 can monitor the toxicity of the current measurement target raw water supplied from the influent water supply unit 10 in real time.

Meanwhile, the raw water filter unit 3000 is configured to filter suspended solids of a certain size or more in the raw water supplied from the influent water supply unit 10 to the sample water storage unit 4000. For example, this raw water filter unit 3000 may be configured to filter suspended solids larger than 100 μm in raw water supplied from the inflow water supply unit 10. Here, of course, the raw water filter unit 3000 can selectively adjust the size of the suspended solids to be filtered by replacing the filter member (not shown) provided in the raw water filter unit 3000.

Such a raw water filter unit 3000 may be provided with an air injection unit (not shown). This air injection unit can remove foreign substances attached to the filter member through air injection. Such an air injection unit, for example, sprays air in a state where the required amount of raw water has been completely introduced from the inflow water supply unit 10 to the sample water storage unit 4000, that is, in a state where there is no raw water passing through the raw water filter unit 3000. Through this, foreign substances attached to the filter member are removed.

Meanwhile, the sample water storage unit 4000 stores raw water filtered through the raw water filter unit 3000, that is, sample water for evaluating toxic substances. Here, when the required amount of sample water is filled in the sample water storage unit 4000 from the raw water tank unit 2000 through the raw water filter unit 3000, the sample water flows from the raw water tank unit 2000 to the sample water storage unit 4000. Supply is interrupted.

In this way, the sample water stored in the sample water storage unit 4000 is supplied to the integrated ecotoxicity monitoring module 6000, which will be described later. The sample water storage unit 4000 may be made of various materials such as stainless steel and acrylic, etc. The material of the sample water storage unit 4000 is not limited to a specific material and may be made of various materials.

Meanwhile, the sampled water storage unit 5000 is configured to receive the same sampling raw water as the raw water supplied to the raw water filter unit 3000 from the raw water tank unit 2000 mentioned above. Specifically, the water collection unit 5000 stores the same raw water supplied from the raw water tank unit 2000 to the raw water filter unit 3000 at the same time as separately sampled raw water.

For example, if it is determined that there are toxic substances in the sample water supplied to the integrated ecotoxicity monitoring module 6000, the water collection storage unit 5000 automatically collects and analyzes the sampling raw water stored in the water collection storage unit 5000. It is sent to Department (7000) to conduct quantitative and qualitative analysis of the raw water using analysis equipment such as GC and ICP. The operational configuration of the water collection storage unit 5000 and the automatic water collection analysis unit 7000 will be described later.

Meanwhile, the real-time influent toxicity monitoring system 1000 may further include an ammonia measurement sensor unit 8000. This ammonia measurement sensor unit 8000 is configured to measure the ammonia concentration in the sample water passing through the raw water filter unit 3000.

The ammonia measurement sensor unit 8000 determines the effect of time on the return water through ammonia measurement. For example, since the amount of raw sludge withdrawn from the initial settling tank may cause an increase in the COD concentration of influent water, it is desirable to determine the effect of time on the return water through the ammonia measurement sensor unit 8000.

In addition, the real-time influent toxicity monitoring system (1000) provides a carbon source by supplying an appropriate carbon source when denitrifying the sample water supplied to the bioreactor of the treatment plant based on the ammonia measurement value measured through the ammonia measurement sensor unit (8000). By optimizing usage, excessive use of carbon sources can be prevented. In other words, by reducing the load on the biological reactor due to excessive injection of the carbon source, it is possible to derive optimal operating conditions and minimize the cost of the carbon source. In addition, the real-time influent toxicity monitoring system (1000) can improve the operating efficiency of the treatment plant by identifying in advance the effects (impacting substances) on the death of organisms due to toxicity through the integrated eco-toxicity monitoring module (6000). In other words, the overall cost of chemicals, such as chemicals for supplying carbon sources for operating the treatment plant and coagulants for phosphorus treatment, can be reduced.

Meanwhile, the integrated ecotoxicity monitoring module 6000 is configured to detect toxic substances in the sample water supplied from the sample water storage unit 4000. This integrated ecotoxicity monitoring module (6000) is equipped with one or more ecotoxicity monitoring units and can monitor toxic substances in the sample water.

The integrated ecotoxicity monitoring module 6000 according to an embodiment of the present invention will be described as an example in which it is equipped with four ecotoxicity monitoring units. Here, the integrated ecotoxicity monitoring module 6000 does not necessarily have to consist of only four ecotoxicity monitoring units, and of course, it may be comprised of various numbers of ecotoxicity monitoring units.

This integrated ecotoxicity monitoring module (6000) includes the Daphnia ecotoxicity monitoring department (6100), the algae ecotoxicity monitoring department (6200), the luminescent bacteria ecotoxicity monitoring department (6300), the sulfated bacteria ecotoxicity monitoring department (6400), and the It may include an integrated control unit 6500.

Here, the Daphnia ecotoxicity monitoring unit 6100 measures the change in movement of Daphnia according to the input of sample water and calculates the first toxicity index.

And the algae ecotoxicity monitoring unit 6200 measures the change rate of fluorescence of algae according to the input of sample water to calculate the second toxicity index.

And the luminescent bacteria ecotoxicity monitoring unit 6300 is configured to calculate the third toxicity index by measuring the rate of change in the amount of luminescence of luminescent bacteria according to the input of sample water.

And the sulfated bacteria ecotoxicity monitoring unit 6400 is configured to calculate the fourth toxicity index from the rate of change in electrical conductivity due to sulfate ions produced by sulfated bacteria according to the input of sample water.

And the integrated control unit (6500) is the first dose calculated from the Daphnia ecotoxicity monitoring unit (6100), the bird ecotoxicity monitoring unit (6200), the luminescent bacteria ecotoxicity monitoring unit (6300), and the sulfated bacteria ecotoxicity monitoring unit (6400). The integrated toxicity index is calculated by integrating the toxicity index through the fourth toxicity index.

In this way, the integrated control unit (6500) calculates the results from the Daphnia ecotoxicity monitoring unit (6100), the bird ecotoxicity monitoring unit (6200), the luminescent bacteria ecotoxicity monitoring unit (6300), and the sulfated bacteria ecotoxicity monitoring unit (6400). Since the integrated toxicity index is calculated based on the toxicity index, the effects of various toxic substances can be estimated more accurately. Here, if the integrated toxicity index value of the sample water calculated through the integrated control unit 6500 is higher than the preset integrated toxicity index value, it is determined that toxic substances exist in the sample water, and the water collection storage unit ( 5000) is supplied to the automatic water sampling analysis unit 7000, and the automatic water sampling analysis unit 7000 analyzes the chemical components more accurately through physicochemical analysis of the raw water.

Specifically, the Daphnia ecotoxicity monitoring unit 6100 includes a housing 6110, a Daphnia ecotoxicity supply unit 6120, a continuous dilution unit 6130, a first chamber unit 6140, a Daphnia optical measurement unit 6150, and a Daphnia ecotoxicity unit. May include a toxicity control unit 6160.

The Daphnia ecotoxicity supply unit (6120) is for supplying samples, culture medium, and algae to the continuous dilution unit (6130) and is provided inside the housing (6110), and the Daphnia sample storage unit (6121) and the first culture medium storage unit (6122) , It may include a first algae storage unit 6123 and a first waste liquid storage unit 6124.

The Daphnia sample storage unit 6121 is filled with sample water provided from the sample water storage unit 4000 for toxicity evaluation. A filter 6125 capable of filtering suspended matter contained in the sample water may be placed within the Daphnia sample storage unit 6121. For example, the filter 6125 may be composed of a metal filter, ceramic filter, fiber filter, filtration membrane, etc.

In this way, the sample water flowing into the Daphnia sample storage unit 6121 is transferred to the sample constant temperature unit 6126. This sample constant temperature unit 6126 is equipped with a constant temperature device using, for example, a Peltier element. Since each aquatic organism lives in a different environment, the optimal temperature must be maintained. The sample constant temperature unit 6126 heats or cools the sample water to keep the temperature of the sample water constant.

The first culture medium storage unit 6122 stores culture medium for diluting the sample. Culture medium is synthetic water prepared to normally cultivate toxicity test organisms.

The first algae storage unit (6123) stores cultured algae, which are food for toxicity test organisms, and is equipped with a refrigeration module. As a result, the first algae storage unit 6123 can maintain the internal temperature at approximately 5 degrees, which is an appropriate temperature at which algae do not deteriorate.

The first waste liquid storage unit 6124 stores a mixture of samples and algae or a mixture of culture medium and algae discharged from the continuous dilution unit 6130 and the first chamber unit 6140.

The continuous dilution unit 6130 mixes the sample and culture medium supplied from the Daphnia sample storage unit 6121 and the first culture medium storage unit 6122 at various mixing ratios to form a plurality of chambers 6141 provided in the first chamber unit 6140. ) to supply mixtures of different dilution ratios.

At this time, the lighting device 6151 is provided on the rear side of the first chamber portion 6140, and the light emitted from the lighting device 6151 passes through the rear of the first chamber portion 6140 made of a translucent material into the chamber 6141. ) The internal accommodation space 6142 is illuminated evenly.

The optical imaging device 6152 consists of an optical camera device capable of digitally recording using elements such as a Charge Coupled Device (CCD) or Complementary Metal-Oxide-Semiconductor (CMOS), and is located in the front of the first chamber unit 6140. The receiving space 6142 inside the transparent chamber 6141 is photographed.

In this way, the image captured by the Daphnia optical measurement unit 6150 is transmitted to the Daphnia ecotoxicity control unit 6160. At this time, of course, the video may be transmitted through a wired connection line or transmitted wirelessly.

The Daphnia ecotoxicity control unit 6160 analyzes the Toxic Index (TI) of the response of organisms to toxic substances based on the image transmitted from the Daphnia optical measurement unit 6150.

In detail, the Daphnia ecotoxicity control unit 6160 tracks the swimming trajectory of aquatic organisms from an image composed of a plurality of frames, and from this, the speed, acceleration, velocity distribution, position distribution within the chamber, activity radius, and total TI measurements such as movement distance, frequency of intermittent hopping (hopping), immersion rate, movement time, stopping time, movement trajectory, rotation angle, and repetitive behavior pattern are derived.

Preferably, the Daphnia ecotoxicity control unit 6160 may generate an integrated TI measurement value that integrates one or more of the plurality of TI measurement values. For example, an integrated TI measurement value can be generated by varying the weight for each parameter.

The detection unit 6232 is provided on the side of the second chamber unit 6220 made of glass and detects fluorescence emitted from algae. For example, the detection unit 6232 may be a photodiode.

Since the rate of change of the general fluorescence amount and the maximum fluorescence amount that occurs in the process of algae using light changes when toxic substances are introduced, the detection unit 6232 detects this, and the rate of change of the fluorescence amount in the normal state is detected in the culture medium chamber 6221. And the rate of change in fluorescence when toxic substances are introduced is detected in the sample water chamber 6222 and the mixed solution chamber 6223.

At this time, the rate of change in fluorescence of algae in uncontaminated standard water quality is detected in the culture medium chamber 6221, and the rate of change in fluorescence of algae exposed to toxic substances is detected in the sample water chamber 6222 and the mixed solution chamber 6223. If toxic substances exist in the sample water, the concentration of the toxic substances increases in the order of the culture medium chamber 6221, the mixed liquid chamber 6223, and the sample water chamber 6222, so the amount of change in fluorescence also increases in the sample water chamber 6222, The mixed liquid chamber 6223 and the culture medium chamber 6221 increase in that order.

The amount of fluorescence detected from the detection unit 6232 is transmitted to the algae ecotoxicity control unit 6240.

In detail, sulfur particles generate sulfate ions by oxygen and sulfating microorganisms, and the sulfate ions change electrical conductivity. At this time, if the sample water contains toxic substances that reduce the activity of sulfating microorganisms, the production rate of sulfate ions changes, and as a result, the electrical conductivity (electrical conductivity increase rate) of the sample water changes.

The electrical conductivity measurement unit 6440 measures the electrical conductivity value of each reaction tank and provides the value to the sulfated bacteria control unit 6450.

The sulfated bacteria control unit 6450 receives the electrical conductivity value of the sample water measured by the electrical conductivity measurement unit 6440 as an electrical conductivity signal, calculates the rate of change in electrical conductivity of the sample water, and calculates the rate of change in electrical conductivity of the sample water. It is used to calculate the toxicity index of toxic substances contained in sample water. Specifically, in order to determine the change in electrical conductivity due to the inflow of toxic substances, the toxicity index of the toxic substance is calculated using the difference between the standard electrical conductivity change rate and the electrical conductivity change rate value of the new sample depending on the concentration of the sample water.

(First toxicity index) is determined by the Daphnia Ecotoxicity Monitoring Department at the ith time. value, (Second toxicity index) is calculated by the Bird Ecotoxicity Monitoring Department at the i time. value, (Third toxicity index) is calculated by the Biotoxicity Monitoring Department of bioluminescent bacteria at the ith time. value, (4th toxicity index) is calculated by the sulfated bacteria ecotoxicity monitoring department at the i time. It means value. Preferably, the integrated toxicity index can be calculated repeatedly at preset time intervals.

Here, w is a weight for the TI value of each biomonitoring species, and the weight for the TI of each biomonitoring species can be derived by dividing each of the first to fourth toxicity indices by the sum of the toxicity indices.

In detail, w1, w2, w3, and w4 can be calculated by the following equation.

According to this, if a specific organism among Daphnia, luminescent bacteria, algae chlorella, and antioxidant bacteria reacts more to toxicity, greater weight is given to that organism, and the accuracy of the integrated toxicity index can be improved.
