Abstract
본 발명은 악취 제거용 흡착제 및 이 흡착제가 구비된 악취 제거용 맨홀에 관한 것으로서, 보다 상세하게는 레드머드 및 알파반수석고를 소정의 비율로 포함함으로써 하수 유래 악취 제거 효과가 뛰어날 뿐만 아니라 내수성이 우수하여 맨홀에 장착되었을 때 장기간 사용할 수 있는, 악취 제거용 흡착제 및 이 흡착제가 구비된 악취 제거용 맨홀에 관한 것이다.The present invention relates to an adsorbent for removing odor and a manhole for removing odor equipped with this adsorbent. More specifically, by including red mud and alpha hemihydrate gypsum in a predetermined ratio, it not only has an excellent effect of removing odor from sewage, but also has excellent water resistance. It relates to an adsorbent for removing malodors that can be used for a long time when mounted in a manhole, and a manhole for removing malodors equipped with this adsorbent.
Description
본 발명은 맨홀에 장착되어 하수 유래 악취를 제거하는 흡착제에 관한 것이다.The present invention relates to an adsorbent that is installed in a manhole to remove foul odors derived from sewage.
악취는 황화수소, 메르캅탄류, 아민류, 기타 자극성 있는 기체상 물질이 사람의 후각을 자극하여 불쾌감과 혐오감을 주는 냄새를 말한다.Bad odor refers to the smell of hydrogen sulfide, mercaptans, amines, and other irritating gaseous substances that stimulate a person's sense of smell and cause discomfort and disgust.
주요 악취 발생원인 생활하수 및 산업폐수 내의 악취물질은 대개 분자량 30∼150g의 저분자 화합물이거나 비교적 휘발성이 있는 물질로서 대부분 유황계 및 질소 계 유기물이 혐기성 분해되면서 발생된다. 이러한 오폐수 내의 유기물이 분해되면서 생성되는 기체로는 황화수소, 암모니아, 이산화탄소 및 메탄가스 등이 있으나 주요 악취물질은 황화수소와 암모니아이며, 이 외에 스카톨, 메르캅탄류, 질소함유 유기물 등도 악취의 원인이 되고 있다. 이중 계란 썩는 냄새를 지닌 황화수소는 독성이 강하고 철, 아연, 구리, 납, 카드뮴 등을 강하게 부식시키는 특징이 있다.Odor substances in domestic sewage and industrial wastewater, which are major sources of odor, are usually low-molecular-weight compounds with a molecular weight of 30 to 150 g or relatively volatile substances, and are mostly generated through anaerobic decomposition of sulfur-based and nitrogen-based organic substances. Gases produced when organic matter in wastewater decomposes include hydrogen sulfide, ammonia, carbon dioxide, and methane gas, but the main odor substances are hydrogen sulfide and ammonia. In addition, skatole, mercaptans, and nitrogen-containing organic substances also cause odor. there is. Hydrogen sulfide, which has the smell of rotten eggs, is highly toxic and strongly corrodes iron, zinc, copper, lead, and cadmium.
국내 기존 도심지에는 하수관거를 매설하면서 오수와 오수를 동시에 배제시키는 합류식 하수관거 시스템을 주로 적용해왔는데, 분뇨정화조와 오수처리시설에서 악취의 주원인인 황화수소가 생성되어 공공하수도로 배출되고, 이렇게 배출된 황화수소는 맨홀 및 빗물받이 등을 통하여 악취를 발생시킨다.In existing urban areas in Korea, a combined sewer pipe system has been mainly applied, which excludes sewage and sewage at the same time by burying sewage pipes. Hydrogen sulfide, the main cause of odor, is generated in excrement septic tanks and sewage treatment facilities and discharged into public sewage. A foul odor is generated through manholes and rainwater drains.
종래 악취를 제거하기 위한 기술로는 악취의 발생을 미연에 방지하는 방법, 각종 오폐수 등에 함유되어 있는 악취물질을 액상에서 제거하는 방법 그리고 각종 오폐수 등에서 발산된 취기를 포집하여 처리하는 방법 등이 적용되어 왔다. 악취의 발생을 사전에 방지하는 방법으로 오폐수 등을 호기성 상태로 유지하여 환원반응에 의한 악취물질의 생성을 방지하거나, 일단 환원된 악취물질을 무기형태로 산화하는 기술이 있다. 또 다른 전통적인 방법으로는 악취물질과 반응하는 약품 예를 들면, 염소, 오존, 과산화수소, 과망산칼륨 등을 첨가하여 화학반응에 의한 산화처리기술이 응용되어 왔다. 그러나 산화처리방법의 경우 악취의 원인물질이 불완전하게 산화되는 경우가 많기 때문에 강력한 산화제를 투입해야 하며, 이에 따라 처리비용이 증가하고 2차 오염이 발생되는 문제가 있다. 액상에서 악취물질을 제거하는 기술로 활성탄 흡착법, 포기조에 의한 미생물 처리법, 포기여과지를 이용한 처리 등이 있으나, 처리를 위한 장치, 설비비 대비 효율이 낮은 것이 문제로 지적되고 있다.Conventional technologies for removing odors include methods of preventing the generation of odors, methods of removing odorous substances contained in various wastewaters, etc. from the liquid phase, and methods of collecting and treating odors emitted from various wastewaters, etc. come. As a way to prevent the generation of odors in advance, there are techniques to prevent the generation of odorous substances by reduction reactions by maintaining wastewater in an aerobic state, or to oxidize the reduced odorous substances to an inorganic form. Another traditional method has been the application of oxidation treatment technology by chemical reaction by adding chemicals that react with odorous substances, such as chlorine, ozone, hydrogen peroxide, and potassium permangate. However, in the case of oxidation treatment methods, since the substances causing bad odor are often incompletely oxidized, a strong oxidizing agent must be used, which increases treatment costs and causes secondary pollution. Technologies for removing odorous substances from liquid include activated carbon adsorption, microbial treatment using aeration tanks, and treatment using aeration filters, but the problem is that their efficiency is low compared to the cost of equipment and equipment for treatment.
한편, 오폐수 내의 악취물질을 탈취 등의 방법으로서 대기 중으로 방출시킨 후 기체상에서 처리하는 방법, 특히 황화수소계 및 암모니아계 물질을 처리하는 기술이 연구 개발되고 있다. 기체상의 악취물질 제거 기술은 크게 물리·화학적 처리와 생물학적 처리로 나눌 수 있는데, 대표적인 물리·화학적 처리기술로는 활성 탄 흡착법, 약액 세정법, 연소법 등이 있으며, 대표적인 생물탈취로는 토양탈취, 포기조 탈취 및 각종 바이오 필터 등을 들 수 있다.Meanwhile, methods for discharging odorous substances in wastewater into the atmosphere as a deodorizing method and then treating them in the gas phase, particularly technologies for treating hydrogen sulfide-based and ammonia-based substances, are being researched and developed. Gas phase odor removal technology can be broadly divided into physical/chemical treatment and biological treatment. Representative physical/chemical treatment technologies include activated carbon adsorption, chemical cleaning, and combustion, and representative biological deodorization include soil deodorization and aeration tank deodorization. and various biofilters.

실험예 1. 흡착 성능 확인Experimental Example 1. Confirmation of adsorption performance
실시예 1의 흡착제를 도 2와 같이 파쇄한 후 일정한 입경(10 내지 18mm)으로 체거름(sieving)하였다. The adsorbent of Example 1 was crushed as shown in FIG. 2 and then sieved to a certain particle size (10 to 18 mm).
흡착실험용 반응기에 상기 체거름된 시료 8cc를 충진하고, H2S 표준가스(20 ppm)를 공간속도 42,000/h의 유량으로 흘렸다. 이때, 상대습도는 90%였다. 이후, 시간에 따른 흡착된 가스량을 H2S 검지관으로 확인하였다.The reactor for the adsorption experiment was charged with 8 cc of the sieved sample, and H 2 S standard gas (20 ppm) was flowed at a space velocity of 42,000/h.

또한 시판품인 산화철 흡착제(비교예 1)와 활성탄 흡착제(비교예 2)도 실시예 1의 흡착제와 마찬가지로 테스트하였다. 흡착 성능 확인 결과는 다음 표 2와 같다.In addition, commercially available iron oxide adsorbents (Comparative Example 1) and activated carbon adsorbents (Comparative Example 2) were tested in the same manner as the adsorbent of Example 1. The adsorption performance confirmation results are shown in Table 2 below.

실험예 2. 내수성 확인Experimental Example 2. Confirmation of water resistance
실시예 1에 따라 제조된 흡착제, 실시예 1의 알파반수석고 대신에 일반석고를 동량 넣은 흡착제(비교예 3) 및 실시예 1의 알파반수석고 대신에 벤토나이트를 동량 넣은 흡착제(비교예 4)를 각각 물을 넣고 24시간 유지시켜 내수성을 확인하였다. 나머지 비교예 3 및 4의 제조방법 및 조건은 실시예 1과 동일하다.The adsorbent prepared according to Example 1, the adsorbent containing the same amount of general gypsum instead of the alpha-semihydrate gypsum of Example 1 (Comparative Example 3), and the adsorbent containing the same amount of bentonite instead of the alpha-semihydrate gypsum of Example 1 (Comparative Example 4). Water resistance was confirmed by adding water to each and maintaining them for 24 hours. The manufacturing methods and conditions of the remaining Comparative Examples 3 and 4 were the same as Example 1.
그 결과 실시예 1의 흡착제는 도 4와 같이 형상을 유지하였으나 비교예 3 및 4의 흡착제는 도 5와 같이 물에 풀어지는 현상이 나타났다.As a result, the adsorbent of Example 1 maintained its shape as shown in FIG. 4, but the adsorbent of Comparative Examples 3 and 4 appeared to be dissolved in water as shown in FIG. 5.

표 3과 같이 실시예 1은 소성 공정을 거치지 않아도 내수성이 우수하다. 벤토나이트를 바인더로 사용한 흡착제는 500℃ 미만으로 소성할 경우에는 내수성 개선 효과가 떨어지고 500℃ 이상으로 소성할 경우에는 온도가 올라갈수록 흡착 성능이 떨어짐을 알 수 있었다.As shown in Table 3, Example 1 has excellent water resistance even without undergoing a firing process. It was found that the adsorbent using bentonite as a binder did not improve water resistance when fired below 500℃, and when fired above 500℃, the adsorption performance decreased as the temperature increased.
