Description

고도하폐수처리장치와 병합한 비점원오염원 제거처리시스템{NONPOINT SOURCE REMOVAL TREATMENT SYSTEM COMBINED WITH ADVANCED WASTEWATER TREATMENT PROCESS}NONPOINT SOURCE REMOVAL TREATMENT SYSTEM COMBINED WITH ADVANCED WASTEWATER TREATMENT PROCESS}

본 발명은 생물학적인 처리방법을 통하여 비점원오염원을 제거하는 장치와 고도하폐수처리장치를 유기적으로 연결하여, 하폐수처리의 효율을 향상시키고 비점원 오염물질을 효과적으로 제거할 수 있는 제거처리시스템에 관한 것이다.The present invention relates to a removal treatment system capable of organically connecting a non-point source pollutant and an advanced sewage treatment apparatus through a biological treatment method to improve the efficiency of wastewater treatment and to effectively remove nonpoint source contaminants. .

비점원오염원은 산재되어 있는 오염원으로서, 오염물질의 정확한 유출경로를 확인하기 어려우며 오염물질의 유입이 비지속적인 오염원을 말한다. 비점원오염원은 또한 발생량/배출량이 강수량 등 기상조건에 크게 좌우되기 때문에 처리시설의 설계 및 유지관리가 어렵다.Non-point source pollutants are scattered pollutants, and it is difficult to identify the exact outflow route of pollutants. Non-point source pollutants are also difficult to design and maintain in treatment facilities, since the amount / emissions are highly dependent on weather conditions such as precipitation.

종래 비점원오염원의 제거에는 물리적 제거장치가 일반적으로 사용되어 왔다. 예를 들면, 유입되는 하수의 유속에 의해 장치내 선회류(vortex)를 일으켜서 이때 발생하는 관성력에 의해 고액 분리되는 고형물들은 중앙에 모아 제거하고, 비교적 양호한 수질은 월류(overflow)하도록 하는 원리의 스월 조절조(SWIRL REGULATOR) 등이 있다.Conventional physical removal devices have generally been used for the removal of nonpoint source pollution sources. For example, the swirl of the principle that the solids separated by the inertial force generated by the inertial force generated by the inflow of sewage flow to collect in the center and remove the relatively good water flow overflow SWIRL REGULATOR.

그러나, 최근에는 생물학적 처리 기능을 포함한 비점원오염원 처리장치가 제시되고 있다. 비점원오염원을 생물학적인 처리방법을 이용하여 처리하는 경우, 갈수기 시에는 미생물의 먹이인 오염물질이 유입되지 않아 생물반응조 안에 미생물을 충분히 확보하기가 매우 어렵다. 또한, 먹이가 유입되지 않는 시간이 길어지게 되면 미생물은 결국 소멸하게 된다. 따라서, 미생물의 유지관리가 이루어지지 않으므로 생물반응의 저하를 초래하게 되며, 이로 인하여 비점원오염원의 제거효율이 떨어지게 되는 문제점이 있었다.Recently, however, a non-point source contaminant treatment apparatus including a biological treatment function has been proposed. In the case of treating non-point source pollutants using biological treatment methods, it is very difficult to secure enough microorganisms in the bioreactor because the pollutants fed by the microorganisms do not flow during the dry season. In addition, the longer the time the food is not introduced, the microorganisms will eventually disappear. Therefore, since maintenance of the microorganism is not made, it causes a decrease in the bioreaction, and thus there is a problem that the removal efficiency of the non-point source pollutant is lowered.

즉, 비점원오염원의 생물학적 처리공정에서는 새로운 미생물을 지속적으로 시딩(SEEDING)하지 못하면 우수기 시 비점원오염원의 생물학적 처리효율은 매우 낮아질 수 밖에 없다. 따라서, 비점원오염원을 생물학적으로 처리하기 위해서는 미생물의 개체수 유지가 필수적이다.In other words, in the biological treatment process of non-point source contaminants, the biological treatment efficiency of the non-point source contaminants will be very low in the case of rainy season when the new microorganism is not seeded continuously. Therefore, it is essential to maintain the population of microorganisms for biological treatment of nonpoint source pollutants.

따라서, 본 발명자들은 비점원오염물질이 발생하지 않는 갈수기 시에도 비점원오염원 제거장치에 미생물을 유지시킬 수 있고, 일부 하수를 비점원오염원 처리시설을 거쳐 다시 하폐수 처리공정으로 유입시킴으로써 하폐수 처리의 효율을 향상시킬 수 있으며, 우수기 시에는 비점원오염물질을 효과적으로 처리할 수 있도록 하기 위하여 하폐수처리를 위해 설치되는 고도하폐수처리장치와 비점원오염원의 처리를 위해 설치되는 비점원오염원 제거장치를 유기적으로 연결하여 본 발명을 완성하였다.Therefore, the present inventors can maintain the microorganisms in the non-point source contaminant removal device even in the dry season when the non-point source contaminants do not occur, and the efficiency of the sewage treatment by introducing some sewage back to the wastewater treatment process through the non-point source contaminant treatment facility. In order to effectively treat nonpoint source pollutants during rainy season, organic wastewater treatment equipment installed for sewage treatment and nonpoint source removal equipment installed for treatment of nonpoint source pollution organically. In connection with this, the present invention was completed.

즉, 본 발명의 목적은 고도하폐수처리장치와 병합한 비점원오염원 제거처리시스템을 제공하는 것이다.That is, an object of the present invention is to provide a non-point source pollutant removal treatment system combined with an advanced sewage treatment system.

Nitric acid nitrogen introduced from the contact biomaterial oxidation unit 50 is nitrogen is removed through the denitrification process in the biological nutrient removal unit 30.

상기 접촉생물질산화부(50)의 배출수를 효과적으로 제거하기 위하여, 고액분리부(90) 유입직전에 약품주입부(90)를 이용하여 약품을 주입하여 유입하폐수(10)를 처리한다. 상기 약품은 고도하폐수처리공정에서 일반적으로 사용되는 것이라면 어느 것이라도 사용할 수 있다.In order to effectively remove the discharge water of the contact biomaterial oxidizing unit 50, a chemical is injected using the chemical injection unit 90 immediately before the solid-liquid separator 90 is introduced to treat the influent wastewater 10. The drug can be used as long as it is generally used in advanced sewage treatment.

Is connected to the line between the non-point source contaminant influent 210 and the contact biooxidation unit 220 and the sewage secondary sedimentation battery outflow line 230. On the other hand, the contact biomass oxidation unit 50 of the advanced sewage treatment apparatus (A) and the contact biooxidation unit 220 of the non-point source pollution removal device (B) is connected to the contact biooxidation tank treatment water line 240.

상기와 같이 하폐수이차침전지유출수라인(230)과 접촉생물산화조처리수라인(240)으로 고도하폐수처리장치(A)와 비점원오염원제거장치(B)를 유기적으로 연결하는 이유는, 고도하폐수처리장치(A)의 이차침전부(40)의 유출수를 비점원오염원제거장치(B)의 접촉생물산화부(220)로 유입시켜 미생물에게 먹이를 공급함과 동시에 미생물을 최적의 상태로 유지시키기 위한 것이다. 또한, 상기 접촉생물산화부(240)에서 미생물에 의해 강화 처리된 유출수를 접촉생물산화조처리수라인(240)을 통해 다시 고도하폐수처리장치(A)의 접촉생물질산화부(50)로 보내기 위한 것이다.The reason for organically connecting the advanced sewage treatment apparatus (A) and the non-point source pollution removal device (B) to the sewage secondary sedimentation battery outflow line 230 and the contact biooxidant treatment water line 240 as described above is because of the advanced sewage treatment The inflow of the secondary settling portion 40 of the device (A) to the contact biooxidation unit 220 of the non-point source pollution removal device (B) to feed the microorganisms and at the same time to maintain the microorganisms in an optimal state . In addition, the effluent fortified by the microorganisms in the contact biooxidation unit 240 is sent back to the contact biomaterial oxidation unit 50 of the advanced wastewater treatment apparatus A through the contact biooxidant treatment water line 240. will be.

미생물 확보에 어려움이 없는 우기시에는 하폐수이차침전지유출수라인(230)과 접촉생물산화조처리수라인(240)을 각각 차단하여, 고도하폐수처리장치(A)와 비점원오염원제거장치(B)를 각각 독립적 운전할 수 있도록 하는 것이 바람직하다. 그리고, 필요에 따라 고도고액분리부(260) 유입직전에 약품주입공정(250)을 추가하여 약품이 인라인(IN-LINE) 혼합으로 비점원오염원유입수와 급속 혼합된 후 고도고액분리부(260)로 공급되도록 구성할 수도 있다. 사용되는 약품은 비점원오염원제거공정에서 일반적으로 사용되는 것이라면 어느 것이라도 사용할 수 있다.During the rainy season, when there is no difficulty in securing microorganisms, the secondary sewage secondary battery effluent line 230 and the contact biological oxidation tank treatment water line 240 are respectively blocked, and the advanced sewage treatment system (A) and the non-point source pollution removal device (B) are separated. It is desirable to allow each to operate independently. Then, if necessary, by adding a chemical injection process 250 immediately before the high solids liquid separation unit 260 flows into the high solids liquid separation unit 260 after the drug is rapidly mixed with the non-point source contaminant inlet by the IN-LINE mixing It can also be configured to be supplied to. The chemicals can be used as long as they are generally used in non-point source removal processes.

본 발명에 따른 하폐수고도처리장치와 병합된 비점원오염원 제거처리시스템에 대하여 좀 더 구체적으로 설명하면 다음과 같다.Referring to the non-point source pollution treatment system combined with the sewage treatment system according to the present invention in more detail as follows.

본 발명은 도 1에서와 같이 유입하폐수(10)가 예비 및 일차처리부(20)로 유입되어 처리된 후, 생물학적영양소제거부(30)에서 유기물질 및 영양소가 제거되고, 이어서 이차침전부(40)에 침전된 미생물은 생물학적영양소제거부(30)와 연결된 슬러지반송라인(70)에 의하여 생물학적영양소제거부(30)의 미생물 농도를 높여주게 된다.In the present invention, after the influent wastewater 10 is introduced into the preliminary and primary treatment unit 20 and treated as shown in FIG. 1, organic substances and nutrients are removed from the biological nutrient removal unit 30, and then the secondary sedimentation unit 40 is removed. Precipitated microorganisms to increase the microbial concentration of the biological nutrient removal unit 30 by the sludge conveying line 70 is connected to the biological nutrient removal unit 30.

또한, 이차침전부(40)의 유출수는 접촉생물질산화부(50)에서 질산화 된 후, 생물학적영양소제거공정(30)에서 탈질과정을 통해 질소가 제거되도록 질산성질소내부반송라인(60)으로 보내지게 되며, 접촉생물질산화부(50)의 배출수의 효과적인 제거를 위하여 약품주입(80) 후 고액분리부(90)를 통해 깨끗한 물로 전환되어 방류된다.In addition, the effluent of the secondary sedimentation unit 40 is nitrified in the contact biomaterial oxidation unit 50 and then sent to the nitric acid internal transport line 60 to remove nitrogen through the denitrification process in the biological nutrient removal process 30. In order to effectively remove the effluent of the contact biomaterial oxidizing unit 50, the drug is injected 80 and then discharged into clean water through the solid-liquid separator 90.

한편, 상기 고도하폐수처리장치(A)와 유기적으로 연결 설치되는 비점원오염원제거장치(B)는 비점원오염원유입수(200)를 스크린(미도시) 등의 예비처리부(210)를 거쳐 접촉생물산화부(220)에서 정화시켜 고도고액분리부(260)를 통해 부유물질이 완전히 제거한 후 비점원오염원처리수로서 방류한다.On the other hand, the non-point source pollutant removal device (B) is organically connected to the advanced sewage water treatment device (A) through the non-point source contaminant influent 200 through a pretreatment unit 210, such as a screen (not shown) contact biooxidation After purifying in the unit 220, the suspended solids are completely removed through the advanced solid-liquid separator 260, and then discharged as non-point source contaminated water.

이 과정에서, 우기시에는 하폐수이차침전지유출수라인(230)과 접촉생물산화조처리수라인(240)을 차단하여 비점원오염원유입수(200)가 예비처리부(210)를 거쳐 미생물이 항상 순응되어 있는 상태로 비점원오염물질 제거를 위한 안정적인 생물학적 처리상태를 유지할 수 있도록 하고 있다.In this process, during the rainy season, the wastewater secondary sedimentation battery outflow line 230 and the contact biological oxidation tank treatment water line 240 are blocked so that the non-point source contaminant influent water 200 passes through the pretreatment unit 210, and the microorganisms are always compliant. It is intended to maintain a stable biological treatment state for the removal of nonpoint source pollutants.

그러나, 오염물질이 유입되지 않아 생물학적으로 비점원오염원을 제거하는데 중요한 역할을 하는 미생물의 확보 및 유지관리가 원활하게 이루어지지 않는 기간인 갈수기에는 고도하폐수처리장치(A)의 이차침전부(40)의 유출수를 비점원오염원의 접촉생물산화부(220)로 유입하여 미생물의 먹이를 공급함과 동시에, 미생물을 최적의 상태로 유지시킨 상태에서 접촉생물산화조처리수라인(240)과 연결된 고도하폐수처리장치(A)의 접촉생물질산화부(50)쪽으로 공급하는 구조를 취함으로써 하폐수처리장치의 효율을 보다 향상시킬 수 있다.However, the secondary sedimentation part 40 of the advanced sewage treatment apparatus (A) in the dry season, during which periods of microorganisms that play an important role in biologically eliminating non-point source pollutants due to no contaminants are not smoothly performed. Effluent water flows into the contact biooxidation unit 220 of the non-point source pollutant source and supplies the microorganisms, and at the same time maintains the microorganisms in an optimal state, and the advanced sewage water treatment connected to the contact biooxidant treatment water line 240. The efficiency of the wastewater treatment system can be further improved by adopting a structure for supplying the apparatus A to the contact biomass oxidation unit 50.
