Description
본 발명은 하수처리 평가방법에 관한 것이다.The present invention relates to a sewage treatment evaluation method.
하수는 각종 공법으로 처리되어 하천으로 방류되고 있다. 이와 함께 하수처리가 제대로 되었는지 지속적으로 평가하여, 오/폐수 등이 생태계 환경으로 유입되지 않도록 관리하는 것이 중요하다.Sewage is treated by various methods and discharged into rivers. In addition, it is important to continuously evaluate whether the wastewater treatment has been properly conducted and to prevent the ozone / wastewater from entering the ecosystem environment.
지금까지는 처리된 하수의 수질을 검사하여 정해진 기준에 적합한지를 판단하는 방법으로 하수처리를 관리하고 있다. 다만, 이러한 방법은 계절에 따른 유량 및 각종 변수에서 생기는 오차를 반영할 수 없다. 또한, 하수처리 수준이 미달함에도 상기 오차 등으로 인해 수질은 기준을 만족하거나 또는 그 반대의 상황도 발생하게 되어, 하수처리 수준을 신뢰할 수 없게 된다.Until now, the sewage treatment has been managed by examining the quality of treated sewage and judging whether it meets a predetermined standard. However, this method can not reflect the seasonal flow rate and errors in various variables. In addition, even if the sewage treatment level is lowered, the water quality meets the standard due to the error or the like, or vice versa, and the sewage treatment level becomes unreliable.
그 결과, 하수처리 수준이 미달됨에도 방치하는 경우가 생겨 제대로 처리되지 않은 하수가 환경으로 유입될 위험성이 크며, 사후적인 대처를 할 수 밖에 없는 실정이다.As a result, even if the sewage treatment level is insufficient, there is a case where the sewage is left untreated. Therefore, there is a great risk that sewage which has not been properly treated is introduced into the environment.
이에 주변 환경 및 유량 등의 변수에도 오차를 최소화할 수 있는 하수처리 평가방법이 필요하다.Therefore, a sewage treatment evaluation method that minimizes errors in variables such as the surrounding environment and the flow rate is needed.
이와 관련한 선행 기술은 한국등록특허 제0522764호에 개시되어 있다.Prior art related to this is disclosed in Korean Patent No. 0522764.

도 1은 본 발명의 일 구체예에 따른 하수처리 평가방법을 간단히 도시한 것이다.BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a simplified view of a sewage treatment evaluation method according to one embodiment of the present invention.
본 명세서에서 "추적자"는 추적자 하나를 의미할 수도 있고, 2 이상의 추적자의 혼합물을 의미할 수도 있다. 추적자가 2 이상의 추적자 혼합물을 의미하는 경우에, 추적자 농도는 각 추적자 농도의 합을 의미한다.As used herein, "tracker" may mean one tracker, or a mixture of two or more trackers. Where the tracer means a mixture of two or more tracers, the tracer concentration means the sum of each tracer concentration.
본 명세서에서 "정상제거율"은 측정 대상인 수처리 장치가 정상적으로 작동하는 경우에, 측정 대상 수처리 장치로 유입되는 유입수에서의 측정한 유입수의 추적자농도에 대한, 측정 대상 수처리 장치로부터 배출되는 배출수에서의 측정한 배출수의 추적자농도의 비(%)를 의미한다.The term "normal removal rate" in this specification refers to the ratio of the measured concentration of the influent water flowing into the measurement target water treatment apparatus to the tracer concentration of the influent water measured in the discharge water discharged from the measurement target water treatment apparatus (%) Of the tracer concentration of the effluent.
본 명세서에서 "유입수"는 하수 처리 전, 하수처리장으로 들어가는 하수를 의미한다.As used herein, "influent" means sewage entering the sewage treatment plant before sewage treatment.
본 명세서에서 "배출수"는 하수 처리 후, 하수처리장으로부터 흘러 나오는 하수처리된 하수를 의미한다.In the present specification, the term "drain water" means sewage treated sewage discharged from a sewage treatment plant after sewage treatment.

본 발명의 일 구체예에 따른 하수처리 평가방법은 도 1에 개시된 바와 같이, 유입수의 제1 추적자농도(C1i) 및 유입수의 제2 추적자농도(C2i)를 측정하여 C1i 및 C2i 값을 얻는 단계; 배출수의 제1 추적자농도(C1e) 및 배출수의 제2 추적자농도(C2e)를 측정하여 C1e 및 C2e 값을 얻는 단계; 및 상기 얻어진 C1i, C2i, C1e 및 C2e로부터 하수처리 평가지수를 산출하는 단계를 포함하고, 상기 제1 추적자는 정상제거율이 10% 이하, 구체적으로 5% 이하이고, 상기 제2 추적자는 정상제거율이 90% 이상, 구체적으로 95% 이상이다.The method for evaluating wastewater treatment according to one embodiment of the present invention is characterized in that the first trace concentration (C 1i ) of the influent water and the second trace concentration (C 2i ) of the influent water are measured to determine C 1i and C 2i values ; Measuring a first tracer concentration (C 1e ) of the effluent and a second tracer concentration (C 2e ) of the effluent to obtain C 1e and C 2e values; And calculating a sewage treatment evaluation index from the obtained C 1i , C 2i , C 1e and C 2e , wherein the first tracer has a normal removal rate of 10% or less, specifically 5% or less, Has a normal removal rate of 90% or more, specifically 95% or more.
유입수의 제1 추적자농도(C1i) 및 유입수의 제2 추적자농도(C2i)는 유입수에서 측정하여 얻는 것일 수 있다. 상기 유입수의 제1 추적자농도(C1i) 및 유입수의 제2 추적자농도(C2i)의 측정은 당업자에게 알려진 방법으로 할 수 있다. 예를 들어, 농도 측정 장치를 사용할 수 있으나, 이에 제한되지 않는다.The first tracker concentration (C 1i ) of the influent water and the second tracker concentration (C 2i ) of the influent water may be obtained by measuring at the influent water. Measurement of the first tracer concentration (C 1i ) of the inflow water and the second tracer concentration (C 2i ) of the inflow water can be performed by methods known to those skilled in the art. For example, a concentration measuring device can be used, but is not limited thereto.
추적자는 하수처리 평가지수를 산출하는 기준이 되는 물질로, 유입수에서 검출 빈도가 높은 것을 사용할 수 있다. 측정 용이성 면에서 추적자는 유입수에서 검출 빈도가 90% 이상, 구체적으로 93% 이상의 물질을 사용할 수 있다.The tracer is a standard for calculating the wastewater treatment evaluation index and can be used with a high detection frequency in influent water. From the viewpoint of ease of measurement, the tracer can use more than 90% of detection frequency, specifically more than 93% of the detection frequency in influent water.
이와 같이, 추적자로는 상기 유입수에 포함되어 있는 물질을 사용할 경우, 별도의 투입물질을 사용하지 않아 하수처리 평가방법이 간편한 장점이 있다.As described above, when a substance contained in the inflow water is used as a tracer, there is an advantage that a method of evaluating a sewage treatment is simple because no additional input material is used.
상기 검출 빈도는 예를 들어, 유입수 100 ml를 복수 회에 걸쳐 채취하는 경우, 상기 유입수에 해당 물질이 포함되는 빈도를 기준으로 할 수 있으나, 이에 제한되지 않는다.For example, when the inflow water 100 ml is collected a plurality of times, the detection frequency may be based on the frequency of inclusion of the substance in the inflow water, but the present invention is not limited thereto.
제1 추적자는 정상제거율이 10% 이하, 구체적으로 5% 이하인 물질 또는 이러한 물질들의 혼합물일 수 있다. 제1 추적자는 하수처리에 의한 제거율이 낮은 물질로써, 제2 추적자의 제거 비율의 기준이 된다. 예를 들어, 제1 추적자는 크로타미톤(crotamiton), 카르바마제핀(carbamazepine), 디클로페낙(diclofenac) 중 하나 이상을 포함할 수 있다.The first tracker may be a material having a normal removal rate of 10% or less, specifically 5% or less, or a mixture of such materials. The first tracker is a material with a low removal rate by sewage treatment, and is a reference for the removal rate of the second tracker. For example, the first tracker may comprise one or more of crotamiton, carbamazepine, diclofenac.
제2 추적자는 정상제거율이 90% 이상, 구체적으로 95% 이상인 물질 또는 이러한 물질들의 혼합물일 수 있다. 제2 추적자는 하수처리에 의한 제거율이 높은 물질로써, 하수처리 기능이 제대로 작동되는 지를 반영한다. 예를 들어, 제2 추적자는 아세트아미노펜(acetaminophen), 카페인(caffeine), 테오필린(theophylline), 이부프로펜(ibuprofen), 나프록센(naproxen) 중 하나 이상을 포함할 수 있다.The second tracker may be a substance having a normal removal rate of 90% or more, specifically 95% or more, or a mixture of such substances. The second tracker reflects whether the sewage treatment function is working properly with high removal efficiency by sewage treatment. For example, the second tracker may include one or more of acetaminophen, caffeine, theophylline, ibuprofen, naproxen, and the like.
상기 제1 추적자 또는 제2 추적자는 2 이상 화합물의 물질을 포함할 수 있다. 2 이상의 물질을 동시에 포함하는 추적자를 적용하는 경우, 평가의 신뢰성을 높일 수 있다. 예를 들어, 2 이상의 추적자 농도의 합을 하수처리 평가지수를 산출하는 단계에서 추적자의 농도로 적용할 수 있다.The first tracker or second tracker may comprise a material of two or more compounds. If a tracer that includes two or more substances simultaneously is applied, the reliability of the evaluation can be increased. For example, the sum of two or more tracer concentrations can be applied as the tracer concentration in the step of calculating the wastewater treatment evaluation index.
본 발명의 하수처리 평가방법은 단순히 제2 추적자의 농도만을 기준으로 하지 않고, 제거율이 낮은 제1 추적자에 대한 제2 추적자의 농도를 하수처리 평가지수를 산출하는 기준으로 함으로써, 계절, 환경에 따른 유량 등의 변화에서 오는 오차를 최소한으로 할 수 있는 장점이 있다.According to the sewage treatment evaluation method of the present invention, the concentration of the second tracer for the first tracer having a low removal rate is used as a reference for calculating the wastewater treatment evaluation index, not merely on the concentration of the second tracer, There is an advantage that the error from the change of the flow rate can be minimized.
배출수의 제1 추적자농도(C1e) 및 배출수의 제2 추적자농도(C2e)를 측정하여 C1e 및 C2e 값을 얻는 단계는 유입수가 아닌 배출수 내의 제1 추적자의 농도 및 제2 추적자의 농도를 측정한다는 점 외에는 상기 유입수의 제1 추적자 농도(C1i) 및 제2 추적자 농도(C2i)를 측정하는 단계와 실질적으로 동일하다.Measuring the first tracer concentration (C 1e ) of the effluent and the second tracer concentration (C 2e ) of the effluent to obtain the values of C 1e and C 2e is accomplished by measuring the concentration of the first tracer in the effluent and the concentration of the second tracer (C 1i ) and the second tracker concentration (C 2i ) of the influent water, except that the first tracker concentration (C 1i ) and the second tracker concentration (C 2i ) are measured.
측정된 C1i, C2i, C1e 및 C2e로부터 하수처리 평가지수를 산출하는 단계는, 예를 들면 하기 식 1에 의해 산출하는 것일 수 있다.The step of calculating the wastewater treatment evaluation index from the measured C 1i , C 2i , C 1e and C 2e may be calculated, for example, by the following equation (1).
[식 1][Formula 1]
하수처리 평가지수(%)=
(상기 식 1에서, C1i은 유입수에서 측정한 유입수의 제1 추적자농도, C2i는 유입수에서 측정한 제2 추적자 유입수농도, C1e는 배출수에서 측정한 배출수의 제1 추적자농도, C2e는 배출수에서 측정한 배출수의 제2 추적자농도임).(In the formula 1, C 1i is a first tracer concentration of the incoming water measured at the inlet water, C 2i is the second tracer influent concentration measured in the inlet water, C 1e of the first tracer concentration in the effluent measured in the effluent, C 2e is The second trace concentration of the effluent measured in the effluent).
상기 산출된 하수처리 평가지수(%)는 하수처리 기능이 제대로 작동되는 지를 반영할 수 있고, 평가지수(%)가 높을수록 하수처리 기능이 우수한 것을 의미한다.The calculated wastewater treatment evaluation index (%) can reflect whether the sewage treatment function is working properly, and the higher the evaluation index (%), the better the sewage treatment function.
다만, 상기 하수처리 평가지수(%)는 반드시 상기 식 1에 의해 계산되어야 하는 것은 아니며, 제거율이 낮은 제1 추적자의 농도와 제거율이 높은 제2 추적자의 비율 또는 차이를 지수화하여 반영할 수 있는 산출식이면 제한 없이 적용이 가능하다.However, the wastewater treatment evaluation index (%) does not necessarily have to be calculated according to Equation (1), but may be calculated by indexing the ratio or difference between the concentration of the first tracer having a low removal rate and the second tracer having a high removal rate The formula can be applied without restrictions.
다른 구체예에 따르면, 상기 유입수의 제1 추적자농도(C1i) 및 유입수의 제2 추적자농도(C2i)는 유입수에서 n 회 측정하고, 하기 식 2로 산출하여 얻는 것일 수 있다.According to another embodiment, the first tracker concentration C 1i of the inflow water and the second tracker concentration C 2i of the inflow water may be obtained by measuring n times in the influent water and calculating the following formula 2.
[식 2][Formula 2]
예측농도(Cxi) = 
(상기 식 2에서, x는 1 또는 2이고, n은 측정 횟수이고, Conxm은 유입수에서 m번째 측정한 제x 추적자의 유입수농도이고, Qm은 m번째 측정 시의 유입수의 유량이고, Qmean은 유입수의 평균유량임).(Where x is 1 or 2, n is the number of measurements, Con xm is the influent concentration of the x-tracker measured at the m-th measurement in the influent, Q m is the flow rate of the influent at the m- mean is the mean flow of the influent).
유입수의 제1 추적자농도(C1i) 및 유입수의 제2 추적자농도(C2i)는 하수처리 전의 추적자 농도로써, 하수처리 기능의 영향을 받지 않는다. 따라서, 하수처리 평가지수에 관한 식에서 유입수의 제1 추적자농도(C1i) 및 유입수의 제2 추적자농도(C2i) 대신, 미리 복수의 회에 걸쳐 측정한 추적자의 농도로, 상기 식 2에 의해 예측농도를 산출하고, 산출한 예측농도(C1ia 및 C2ia)를 유입수의 제1 추적자농도(C1i) 및 유입수의 제2 추적자농도(C2i)로 적용할 수 있다. 미리 산출한 예측농도를 적용하는 경우에는, 배출수에서 배출수의 제1 추적자농도(C1e) 및 배출수의 제2 추적자농도(C2e)만을 측정하여 하수처리 평가지수(%)를 산출할 수 있으므로, 하수처리 평가방법이 더욱 간편해 지는 장점이 있다.The first tracer concentration (C 1i ) of the influent and the second tracer concentration (C 2i ) of the influent are the tracer concentration before the sewage treatment, and are not affected by the sewage treatment function. Therefore, in the equation relating to the wastewater treatment evaluation index, instead of the first tracer concentration (C 1i ) of influent water and the second tracer concentration (C 2i ) of the influent water, The predicted concentrations can be calculated and the calculated predicted concentrations C 1ia and C 2ia can be applied to the first tracker concentration C 1i of the influent water and the second tracker concentration C 2i of the influent water. (%) Can be calculated by measuring only the first tracer concentration (C 1e ) of the effluent water and the second tracer concentration (C 2e ) of the effluent water in the effluent water, There is an advantage that the sewage treatment evaluation method becomes simpler.
상기 식 2에 의한 예측농도는 신뢰성을 높이기 위해, 복수 회에 걸쳐 농도를 측정하고, 측정된 농도를 반영하여 예측농도를 산출하는 방법일 수 있다. 상기 예측농도는 측정회수가 많을수록 신뢰도가 높아진다. 구체적으로 상기 식 2는 n회 측정한 데이터를 이용하여 농도를 예측하는 산출식으로써, 신뢰성을 높이기 위해 n은 2 이상, 구체적으로 4 이상일 수 있고, 이에 제한되지 않는다. 4회 이상 농도를 측정하는 경우 온도변화에 따른 변화에 따른 오차를 줄일 수 있는 장점이 있다.In order to increase the reliability, the predicted concentration according to Formula 2 may be a method of measuring the concentration plural times and calculating the predicted concentration reflecting the measured concentration. The reliability of the predicted density increases as the number of measurements increases. Specifically, Equation 2 is a calculation formula for predicting the concentration using data measured n times. In order to increase the reliability, n may be 2 or more, specifically 4 or more, but is not limited thereto. When the concentration is measured more than 4 times, there is an advantage that the error according to the change according to the temperature change can be reduced.
다만, 상기 예측농도는 반드시 상기 식 2에 의해 계산되어야 하는 것은 아니며, 복수 회 측정된 농도를 반영할 수 있는 산출식이면 제한 없이 적용이 가능하다.However, the predicted concentration does not necessarily have to be calculated according to Equation (2), and can be applied without limitation as long as it is an equation that can reflect the concentration measured plural times.

상기 표 1 및 표 2에서 N.D.(Not detected)는 추적자가 검출되지 않았음을 의미한다. In Table 1 and Table 2, N.D. (Not detected) means that no tracer was detected.
상기 표 1 및 표 2에서 알 수 있듯이, 본원발명의 하수처리 평가방법은 유량이 정상인 상태뿐만 아니라, 유량이 증가한 상태에서도 하수처리의 수준을 정확하게 평가하는 것을 알 수 있다. 그러나, 기준의 수질 기준은 유량의 증가로 희석되는 효과로 인해, 하수처리가 제대로 되지 않음에도 이를 반영하지 못하는 것을 알 수 있다. 구체적으로 유량증가 2의 경우, 하수처리장이 기능을 상실하고 복구되는 과정에서, 기존의 수질기준은 만족하지만, 본원발명의 하수처리 평가지수는 낮게 평가되어 정상 상태로의 회복이 되지 않은 것을 알 수 있으며, 이는 기존 보다 정확하게 하수처리의 수준을 평가할 수 있다는 것을 의미한다.As can be seen from Tables 1 and 2, it can be seen that the sewage treatment evaluation method of the present invention accurately evaluates the level of sewage treatment not only in a normal flow rate but also in an increased flow rate. However, it can be seen that the reference water quality standard does not reflect the fact that sewage treatment is not performed properly due to the dilution effect due to the increase of the flow rate. Specifically, in the case of the increase of the flow rate 2, in the process of the loss of the function of the sewage treatment plant and the recovery of the function, the existing water quality standard is satisfied, but the sewage treatment evaluation index of the present invention is evaluated to be low, , Which means that the level of sewage treatment can be assessed more precisely than before.
