Description

폐수처리용 담체 및 그것을 이용한 폐수처리장치{MATERIAL FOR WATER-TREATING AND WATER-TREATING APPARATUS} Wastewater Treatment Carrier and Wastewater Treatment Equipment Using the Same {MATERIAL FOR WATER-TREATING AND WATER-TREATING APPARATUS}

본 발명은 오폐수의 생물학적처리를 위한 생체물질의 담체 및 그것을 이용한 폐수처리장치에 관한 것으로, 보다 상세하게는 제오라이트와 송이(scoria) 및 이온대전광물을 결합하여 구성한 담체 및 담체를 다단계 폭기조에 배치 구성한 폐수처리장치에 관한 것이다.The present invention relates to a carrier of a biological material for biological treatment of wastewater and a wastewater treatment apparatus using the same, and more particularly, a carrier and a carrier formed by combining zeolite, scoria, and ion charged minerals are arranged in a multistage aeration tank. It relates to a wastewater treatment device.

송이는 일명 스코리아라고 하는 것으로 제주지역에서 다량으로 매장된 화산분출물로 SiO2, Al2O3,Fe2O3,CaO,MgO가 주로 포함되어 다공질 형태로 존재한다. 또한, PH 6.5~8.5사이의 알칼리성으로서 효소나 미생물 등의 부착과 고정화가 우수하여 일반적으로 사용하는 생물학적 폐수처리의 생체물질의 담체로서 그 유용성이 입증되고 있고, 비중이 낮은 특성을 활용하여 각종 경량 구조재, 다공성을 이용한 방음, 보온 및 단열재로 활용되고 있으며, 신소재 및 각종 의약제제로도 활용되고 있다.Song-yi is called S Korea and is a volcanic eruption buried in Jeju. It contains SiO 2 , Al 2 O 3 , Fe 2 O 3 , CaO, and MgO. In addition, it is alkaline between PH 6.5 and 8.5 and has excellent adhesion and immobilization of enzymes and microorganisms, and thus its usefulness has been proved as a carrier of biological materials for biological wastewater treatment. It is used as a structural material, soundproofing using heat insulation, insulation and insulation, and is also used as a new material and various pharmaceuticals.

상기한 폐수처리공정에서 송이의 일반적 이용방법은 모래나 자갈 크기의 둥근 입자로 가공하여 폭기조의 중간에 그물층을 형성한 후 그 안에 넣고, 생체물질을 부착 고정화시키는 담체로 활용하는 방법이 있고, 더 나아가 특허등록제0425245에 제시된 바와 같이, 스코리아 입자에 폴리에틸렌이민(PEI)을 코팅하여 미생물의 고정화를 향상시킨 방법으로 활용되고 있다.In the wastewater treatment process, the general method of matsutake is a method of forming a net layer in the middle of the aeration tank by processing it into round particles of sand or gravel size, and using it as a carrier for attaching and immobilizing biomaterials. Furthermore, as shown in Patent Registration No. 0425245, it is used as a method to improve the immobilization of microorganisms by coating polyethyleneimine (PEI) on the SukKorea particles.

이와 같은 송이에 의한 담체는 합성수지 등을 이용한 담체보다 미생물등 생체물질의 부착과 고정화가 우수하고, 처리효율 또한 높으나 여전히 각종 부상물질이나 유기물질과의 접촉이 짧은 폭기 시간 동안 만 효율적으로 이루어지기 때문에 전체적인 처리능력이 높지 않는 측면이 있다. 즉, 폐수의 유입이 이루어진 후 일정시간동안 폭기에 의해 호기성 반응을 유도하면 세균 군이 응집하여 깃털 또는 해면(海綿)처럼 덩어리를 형성하여 중력 침강하는 동안 운전을 정지시켜 오니의 침전을 유도하는 방법이 사용됨으로서 전체적인 반응처리 시간이 길어져 오폐수의 유입이 급격히 증가되는 경우, 오폐수의 부하가 변하는 경우에 신축적으로 대응할 수 없는 등 처리능력에 한계가 있으며, 질소(N) 또는 인(P)과 같은 필수 영양원소의 결핍에 의한 Bulking을 방지하기 위해 고도의 운전제어가 요구된다.Such carriers have better adhesion and immobilization of biological materials such as microorganisms than the carriers made of synthetic resins, and have high treatment efficiency, but still make efficient contact with various floating substances or organic materials only during a short aeration time. The overall processing capacity is not high. That is, if aerobic reaction is induced by aeration for a certain time after the inflow of wastewater, bacterial groups aggregate to form agglomerates like feathers or sea sponges and stop the operation during gravity settling to induce sedimentation of sludge. When this is used, the overall reaction treatment time is long and the inflow of waste water is rapidly increased, and there is a limit in treatment capacity such as when the load of waste water is changed, it cannot be flexibly handled, and nitrogen (N) or phosphorus (P) High operational control is required to prevent bulking due to lack of essential nutrients.

한편, 제오라이트(Zeolite)는 신생대 3기층의 화산재가 속성 작용을 받아 생성된 다공물질로 표면적이 1000㎥/g 이를 만큼 넓어 질소나 인산가리 등의 물리적 흡착력이 매우 높고, 수분이외의 물질을 자체 중량의 거의 20배까지 흡수한 후 서서히 방출하는 특성이 있어 종래 악취제거제나 정수제등 수처리제로 활용되고 있으나 그 자체가 강력한 이온교환제이며, 촉매반응에 의해 양이온을 양성자(H+)로 교환시키는 강력한 고체산으로서 특성 때문에 생체물질의 고정화를 방해하는 작용을 함으로서 담체로서는 거의 사용되고 있지 않다.On the other hand, zeolite is a porous material produced by volcanic ash of the three tertiary layers, and has a surface area of 1000㎥ / g. It is absorbed up to 20 times and then released slowly, so it is used as a water treatment agent such as deodorant or water purifier. However, it is a powerful ion exchanger and itself is a powerful ion exchanger to exchange cations for protons (H + ) Because of its properties as a solid acid, it has a function of hindering the immobilization of a biological material and is therefore rarely used as a carrier.

본 발명은 알칼리성으로서 생체물질의 담체로서 유용하게 사용되는 송이와, 각종 물질의 흡착능력이 높은 제오라이트 분말 및 제오라이트의 산성화를 방지하기 위해 음으로 대전된 광물 분말을 시멘트로 결합하여 알갱이 구조로 구성한 담체와, 이러한 담체를 사용하여 효과적인 수처리가 이루어지도록 구성한 오폐수처리장치를 제공하는 것을 목적으로 한다. The present invention is a carrier composed of a grain structure by combining a cluster which is alkaline and usefully used as a carrier of a biological material, a zeolite powder having high adsorption capacity of various substances, and a negatively charged mineral powder with cement to prevent acidification of the zeolite. And it is an object of the present invention to provide a waste water treatment apparatus configured to achieve an effective water treatment using such a carrier.

이와 같은 목적을 달성하기 위한 본 발명은 송이, 음으로 대전한 광물의 분말 및 제오라이트 분말을 액상 결합제를 사용하여 소성함으로서 알갱이 구조로 구성한 담체를 제공한다. The present invention for achieving the above object provides a carrier having a granular structure by calcining the powder of the cluster, negatively charged minerals and zeolite powder using a liquid binder.

또한, 본 발명은 상기 담체를 충전하여 각 폭기조의 유입구에 배치 구성하여 수처리 능력을 향상시킨 오폐수처리장치를 제시한다.In addition, the present invention proposes a wastewater treatment apparatus which fills the carrier and is arranged at the inlet of each aeration tank to improve the water treatment capability.

이하 본 발명은 상세하게 설명한다.Hereinafter, the present invention will be described in detail.

본 발명에 의한 송이는 제주도에서 용이하게 채취할 수 있는 것으로, 크기나 형상에 관계없이 채취하여 2 ~ 40mm 범위의 크기로 파쇄한 것을 사용한다.The clusters according to the present invention can be easily collected in Jeju Island, regardless of the size or shape, and used to crushed in the size of 2 ~ 40mm range.

상기한 송이는 SiO2, Al2O3,Fe2O3,CaO,MgO가 주로 포함되어 있고, 그외 산화칼륨, 산화나트륨, 이산화티탄등이 적은 량 포함되어 있으며, 그 자체로서 산소의 용해효율이 높고, 암모니아 및 인의 흡착처리능력이 있으며, 탈취, 탈색 및 중금속의 제거 정화능력 능력이 우수하다. 또한, 비표면적이 100 ㎡/g 인 다공성으로서 미생물 등의 생체물질이 부착 고정화가 용이하며, 2 ~ 40mm 의 크기의 알갱이로 상품화되어 경제적으로 용이하게 구입할 수 있다.The cluster is mainly composed of SiO 2 , Al 2 O 3 , Fe 2 O 3 , CaO, MgO, and other small amounts of potassium oxide, sodium oxide, titanium dioxide, and so on. It has high ability to adsorb and treat ammonia and phosphorus, and deodorize, decolorize and remove heavy metals. In addition, it is porous with a specific surface area of 100 m 2 / g and is easily attached and immobilized by biomaterials such as microorganisms, and is commercialized as granules having a size of 2 to 40 mm, and can be easily purchased economically.

제오라이트 분말은 이온교환제로서 통상 수처리 분야에서 암모니아성 질소와 중금속의 제거에 사용되고 있고, 금속 담체로도 활용되고 있으나 생물학적 폐수처리시설의 미생물등의 부착 고정을 위한 담체로 거의 사용되고 있지 않다. 이는 담체로서의 탁월한 물리적 특성에도 불구하고, 양이온을 양성자로 교환시켜 강산성을 띤 고체산으로 변하기 때문에 미생물의 부착 고정화에 유리하지 않는 환경을 제공하는 것이 그 한 원인이다.Zeolite powder is commonly used as an ion exchanger for the removal of ammonia nitrogen and heavy metals in the field of water treatment, and is also used as a metal carrier, but is rarely used as a carrier for fixing and fixing microorganisms in biological wastewater treatment facilities. This is due to the fact that, despite the excellent physical properties as a carrier, the cation is exchanged into protons to turn into a strongly acidic solid acid, thereby providing an environment that is not favorable for the immobilization of microorganisms.

본 발명은 상기한 제오라이트 자체의 정화능력을 이용하고, 각종 유기물질과 중금속 등을 흡착한 후 서서히 방출하는 능력을 이용하여 생체물질에 지속적인 영양염류를 제공함으로서 반응을 지속화시켜 전체적인 오폐수 처리능력을 향상시키고, 반응시간을 단축시킬 수 있도록 한다.The present invention utilizes the purifying capacity of the zeolite itself, and provides continuous nutrients to biological materials by using the ability to adsorb various organic materials and heavy metals and then gradually release them, thereby sustaining the reaction to improve the overall wastewater treatment capacity. To reduce the reaction time.

이를 위하여 상기한 제오라이트 분말과 음으로 대전된 광물의 분말 및 바인더로서 액상결합제를 사용하여 송이와 함께 결합함으로서 제오라이트의 세공 속에 포함된 양이온이 양성자로 교환되어 고체산으로 변하는 것을 방지한다.To this end, by binding together with clusters using a liquid binder as a powder and a binder of the above-mentioned zeolite powder and negatively charged minerals, cations contained in the pores of the zeolite are prevented from being converted into protons.

제오라이트 분말과 음으로 대전된 광물의 분말은 송이에 대하여 중량비로 1~2% 가 되게 하더라도 제오라이트 분말 및 음으로 대전된 광물 분말의 효과를 얻을 수 있으며, 알갱이 형태의 송이 외표면에 상기 제오라이트 분말과 음으로 대전된 광물의 분말이 불규칙한 형태로 부착상태를 유지할 수 있도록 액상결합제를 사용하여 소성하는 방법으로 담체를 제조한다.The zeolite powder and the negatively charged mineral powder can achieve the effect of the zeolite powder and the negatively charged mineral powder even if the weight ratio is 1 to 2% with respect to the cluster, and the zeolite powder and The carrier is prepared by baking using a liquid binder so that the negatively charged mineral powder can remain attached in an irregular form.

상기한 담체의 상세한 실시례는 다음과 같다.Detailed examples of the carrier are as follows.

담체의 실시예 Examples of Carriers

제오라이트 덩어리를 파쇄기로 분쇄한 후 앤드밀로 미분쇄하여 200 mesh 크기의 제오라이트 분말을 얻었다. 장석을 동일한 방법으로 분말화 하여 200 mesh 크기의 제오라이트 분말을 얻고, 이를 액상 결합제와 1:1:1의 중량비로 혼합하였다.The zeolite mass was pulverized with a crusher and then pulverized with an end mill to obtain a zeolite powder having a size of 200 mesh. Feldspar was powdered in the same manner to obtain a zeolite powder of 200 mesh size, which was mixed with the liquid binder in a weight ratio of 1: 1: 1.

바인더로서 시멘트를 사용할 수 있으나 생체물질의 부착 고정능력이 감소되기 때문에 독성이 없고 저온 소성이 가능한 이연사의 액상결합제를 사용하였다. 송이 100kg을 넣고 교반하면서 상기 혼합물 1kg을 살포하여 송이와 혼합물을 부착하였다. 송이와 혼합물이 충분히 혼합 교반된 후 표면이 건조된 상태에서 150~300℃의 오븐에 넣고 1시간 가열하여 소성시켜 대략 5mm내외의 크기를 갖는 담체를 얻었다. 상기에서 얻어진 담체는 음으로 대전된 광물 분말 및 제오라이트 분말이 특유의 세공을 유지하면서 송이 표면의 불규칙한 표면으로 스며들거나 덧부착되어 일체화되는 형태로서 쉽게 파손되지 않고 사용후 세척함으로서 재활용할 수 있는 특성이 있다.Cement can be used as the binder, but the liquid binder of the twisted yarn is used because there is no toxicity and low-temperature firing because the adhesion of biomaterials decreases. 100 kg of clusters were added and 1 kg of the mixture was sprayed while stirring to attach the clusters and the mixture. After thoroughly mixing and stirring the clusters and the mixture, the resultant was placed in an oven at 150 to 300 ° C. with a surface dried, and then heated and calcined for 1 hour to obtain a carrier having a size of about 5 mm. The carrier obtained above is a form in which negatively charged mineral powders and zeolite powders are permeated or attached to irregular surfaces on the surface of clusters while maintaining their unique pores, and are integrated and thus not easily broken. have.

실시예에서 제조한 담체의 COD제거율과 미생물부착량을 측정하기 위하여 상기한 담체를 단순한 형태의 그물에 넣어 폭기조에 대략 20%정도가 되도록 충전한 후 체류시간을 4시간으로 하여 폐수를 유입시키고, 조업 4일 후에 미생물부착량 및 COD를 측정하였다. 이때 활성오니를 고정화에 사용하였으며, 표준공정시험법에 제시된 바에 따라 포도당, 황산암모늄,염화철,수산화인산칼륨,염화칼슘 및 황산망간을 규정된 비율로 혼합한 혼합폐수를 사용하였다.In order to measure the COD removal rate and microbial adhesion amount of the carrier prepared in Example, the carrier was put in a simple net, so that the aeration tank was about 20%, and the wastewater was introduced with a residence time of 4 hours. After 4 days, the microbial attachment and COD were measured. At this time, activated sludge was used for immobilization, and a mixed wastewater in which glucose, ammonium sulfate, iron chloride, potassium phosphate, calcium chloride and manganese sulfate was mixed in a prescribed ratio was used as indicated in a standard process test method.

미생물의 부착량 측정은 실험 종료후 담체를 0.85%(w/v) NaCl용액으로 세척하고, 이를 건조한 후 0.5N NaOH용액으로 담체에 부착한 세포를 탈착하며, NaOH용액을 오븐에서 건조하여 담체당 미생물의 무게를 측정하였다. Determination of adhesion amount of microorganisms was carried out after washing the carrier with 0.85% (w / v) NaCl solution, dried and detached the cells attached to the carrier with 0.5N NaOH solution, and dried NaOH solution in the oven to microorganisms per carrier The weight of the was measured.

비교를 위하여 5mm크기의 송이를 사용하여 폭기조에 대략 20%정도가 되도록 충전한 후 체류시간을 4시간으로 하여 폐수를 유입시키고, 조업 4일 후에 미생물부착량을 측정하였다. 이때 활성오니 및 혼합폐수는 동일하게 적용하였다.For comparison, a 5 mm-size cluster was used to fill the aeration tank to approximately 20%, and the wastewater was introduced with a residence time of 4 hours, and the amount of microorganisms was measured after 4 days of operation. At this time, activated sludge and mixed wastewater were applied in the same way.

상기 실시예와 비교예의 시험결과는 다음 표와 같다.Test results of the Examples and Comparative Examples are shown in the following table.

상기한 비교 결과에 의하면 동일조건에서 송이만 사용하였때 본 발명에 의한 담체 사용시 담체의 COD제거율이 높고, 단기에 높은 COD제거율을 갖는 특성이 있음을 알 수 있고, 미생물부착량의 경우는 송이만 사용하였을 때보다 높게 나타나지만 기존의 개량화된 담체와 거의 비슷한 수준( 통상 29~30mg/g)을 보임을 알 수 있었다.According to the above comparison results, when using only the pine under the same conditions, the use of the carrier according to the present invention shows that the carrier has a high COD removal rate, and has a high COD removal rate in the short term. Although higher than when shown, it was found that the level is almost similar to the conventional improved carrier (usually 29 ~ 30mg / g).

본 발명에 의한 담체 사용시 초기에 COD 제거효율이 높은 결과는 본 발명을 유동상 구조에 사용하는 담체 또는 개방된 채널구조의 바닥에 깔고 폐수를 흘러주는 방식의 폐수 처리시설에도 유용한 효과를 제공할 수 있음을 알 수 있게 하며, 통상적인 활성오니법에 의한 폐수처리시설에서도 처리 시간을 크게 단축할 수 있음을 보여 준다. 또한, 상기한 결과는 통상적인 폭기조에 있어서 담체의 충전량(30~40%)보다 낮은 충전량에서 얻어진 결과로서 본 발명에 의한 담체가 활성오니에 의한 생물학적 폐수 처리법에 유용한 구조임을 보인 것이다.The high COD removal efficiency at the initial use of the carrier according to the present invention may provide a useful effect for wastewater treatment facilities in which the present invention is laid on the bottom of the carrier or open channel structure used in the fluidized bed structure. In addition, it shows that the treatment time can be greatly reduced even in the conventional wastewater treatment plant by the activated sludge process. In addition, the above results show that the carrier according to the present invention is a useful structure for the treatment of biological wastewater by activated sludge as a result obtained at a charge lower than that of the carrier (30-40%) in a conventional aeration tank.

본 발명은 상기한 담체를 특성을 효과적으로 활용할 수 있도록 하기 위하여 폭기조의 입수구측에 활성오니층을 형성한 구조의 폐수처리장치를 제시한다.The present invention proposes a wastewater treatment apparatus having an active sludge layer formed on the inlet side of an aeration tank in order to effectively utilize the characteristics of the carrier.

At this time, the diffuser 90 is repeatedly operated and stopped.

폐수중에 포함된 각종 유기물질 및 무기영양원은 담체를 통과하는 도중에 담체의 표면을 이루는 세공에 흡수 저장되어 미생물에 의해 분해되며, 폐수 유입이 정지되면 담체에 흡수 저장된 이들 물질이 서서히 유출되면서 지속적인 처리가 이루어진다.Various organic materials and inorganic nutrients contained in the waste water are absorbed and stored in the pores forming the surface of the carrier during the passage of the carrier, and are decomposed by microorganisms.

활성오니를 고정화에 사용하였으며, 표준공정시험법에 제시된 바에 따라 포도당, 황산암모늄,염화철,수산화인산칼륨,염화칼슘 및 황산망간을 규정된 비율로 혼합한 혼합폐수를 사용하였다.Activated sludge was used for immobilization, and mixed wastewater containing glucose, ammonium sulfate, iron chloride, potassium hydroxide phosphate, calcium chloride and manganese sulfate in a prescribed ratio was used as indicated in the standard process test method.

비교를 위하여 상기 시험 폭기조의 중간층에 폭과 길이 각 2m, 높이 0.3m 로 활성오니층을 형성하여 내부에 상기 실시예에 의해 제조된 담체를 완전 충전한 후 입수구를 통하여 체류시간을 4시간으로 조정한 폐수를 유입시키고, 조업 1일, 4일 후에 각각 COD를 측정하였다.For comparison, an active sludge layer was formed in the middle layer of the test aeration tank with a width and length of 2 m and a height of 0.3 m, and then completely filled with the carrier prepared by the above example, and then the residence time was adjusted to 4 hours through the inlet. One wastewater was introduced and COD was measured 1 and 4 days after each operation.

시험 결과의 비교는 다음 표와 같다.A comparison of the test results is shown in the following table.

처리장치의 비교결과Comparison results of processing devices

구분 division 조업 1일 후COD 제거율(%) % COD removal after 1 day of operation 조업 4일 후COD 제거율(%) % COD removal after 4 days 실시예 Example 89 89 97 97 비교예 Comparative example 83 83 97 97

상기한 비교 결과에 의하면 조업 4일 후 COD제거율에서는 비교예와 차이가 없으나 조업 1일 후에는 대략 6% 처리율이 향상된 결과를 나타내었다.According to the above comparison result, the COD removal rate after 4 days of operation was not different from the comparative example, but after 1 day of operation, the treatment rate was improved by about 6%.

상기한 비교결과에 의하면 본 발명에 의한 담체 사용시 최종 처리 결과는 다소 앞서지만 초기 초기결과는 많은 차이가 있는 것으로서 폭기조를 다단계로 구성할 경우 폐수의 처리시간을 현저히 단축시킬 수 있음을 보인 것이다.According to the above comparative results, the final treatment result when using the carrier according to the present invention is somewhat advanced, but the initial initial result shows that there is a lot of difference. When the aeration tank is configured in multiple stages, it shows that the treatment time of the wastewater can be significantly shortened.

이상의 구성과 같은 본 발명에 의하면 폐수의 처리속도를 향상시킬 수 있으며, 처리율 또한 향상된 우수한 담체 및 그것을 이용한 폐수처리장치를 얻을 수 있다. According to the present invention as described above, it is possible to improve the treatment speed of the wastewater, it is possible to obtain an excellent carrier and the wastewater treatment apparatus using the same with improved throughput.
