Abstract

PURPOSE: A process is provided, which is characterized in that sewage and wastewater of agricultural villages are treated by water hyacinth ponds(WHPs) and waste stabilization ponds(WSPs). CONSTITUTION: Sewage and wastewater flow into previously water hyacinth ponds(p-WHPs)(2), waste stabilization ponds(WSPs)(1), follow-up water hyacinth ponds(f-WHPs)(3) in order. In the previously water hyacinth ponds(p-WHPs)(2), settleable suspended solid is settled, and suspended solid is removed by roots of water hyacinth. In the waste stabilization ponds(WSPs)(1), suspended solid is settled, and soluble phosphate and nitrogen is removed by algae synthesis. In the follow-up water hyacinth ponds(f-WHPs), algae and remained suspended solids are removed by roots of water hyacinth.

Description

수생 히야신스 처리지와 산화지를 결합한 농촌형 통합 자연 하수/폐수 처리 공법{Integrated-ponds system by coupling waste stabilization ponds with water hyacinth ponds}Integrated-ponds system by coupling waste stabilization ponds with water hyacinth ponds

본 발명은 농촌형 통합 하수/폐수처리시스템에 관한 것으로, 기계적인 처리구조를 갖추지 않고 수생 히야신스 처리지와 산화지를 배열기법으로 설치하여 하수 및 폐수처리가 이루어지도록 한 것이다.The present invention relates to a rural-type integrated sewage / wastewater treatment system, which does not have a mechanical treatment structure and installs aquatic hyacinth treated paper and an oxidized paper by arranging techniques to treat sewage and wastewater.

일반적으로 하수-폐수의 처리시설은 다양한 처리목표를 가지고 설계할 수 있는데, 대부분은 다음중의 몇몇 목표 또는 아래에 제시한 전체목표를 달성하기 위하여 설계할 수 있다.In general, sewage-wastewater treatment plants can be designed with various treatment targets, most of which can be designed to achieve some of the following objectives or the overall objectives set out below.

(1) 부유물질의 제거, (2) 유기물질의 제거, (3) 영양염류의 제거, (4) 미생물학적으로 안전한 처리수질 확보, (5) 독성물질(중금속 포함)의 제거,(1) removal of suspended solids, (2) removal of organic substances, (3) removal of nutrients, (4) ensuring microbiologically safe treatment water, (5) removal of toxic substances (including heavy metals),

기계적인 요소가 많은 공학적인 처리시스템(engineered processes)에서는 상기한 처리목표에 따라 1차처리(부유물질의 제거), 2차처리(유기물질의 제거), 3차처리(영양염류의 제거), 살균등과 같이 분류하며, 지난 30여년 동안 상기와 같은 목표를 달성하고자 각 단위공정을 정형화/배열화 하고자 수많은 노력을 기울여 왔으며, 일반적으로 도시하수를 처리할 경우 각 처리목표를 달성하기 위해서 부가적인 단위공정을 추가하는 것이 보통이나 이는 막대한 재정이 요구되기도 한다.In engineered processes with a lot of mechanical elements, the first treatment (removal of organic substances), the second treatment (removal of organic substances), the tertiary treatment (removal of nutrient salts), In the past 30 years, numerous efforts have been made to formalize / arrange each unit process in order to achieve the above goals, and in general, when treating municipal sewage, additional treatment is required to achieve each treatment goal. It is common to add unit processes, but this may require a huge amount of finance.

그러나, 농어촌지역(읍,면,리)에서는 농어촌지역 수계의 수질관리를 위해서 앞서 제시한 처리목표 중 일부를 달성하고자 할 때 흔히 도시지역에 건설/운영하고있는 고비용의 환경기초시설을 설치하는데는 재원상 현실적으로 불가능하다.However, in rural areas (Eup, Myeon, Ri), to achieve some of the aforementioned treatment goals for water quality management in rural areas, it is often not possible to install expensive environmental foundations that are being constructed / operated in urban areas. In reality, it is impossible to finance.

본 발명은 농어촌지역에서 앞서 제시한 5가지의 하-폐수 처리목표를 달성하는데 가급적 기계적인 요소를 배제하고, 유지관리가 용이하도록 한 것으로, 농어촌 지역에서 발생되는 하수-폐수내의 유기물질의 제거뿐만아니라 영양염류, 병원성 미생물의 제거에 탁월한 효과를 가지고 있는 산화지를 기본 처리시스템으로하고 수생 히야신스 처리지와 결합한 통합 처리시스템에 관한 것이다.The present invention removes mechanical elements as much as possible to achieve the above five sewage-water treatment targets in the farming and fishing areas, and facilitates maintenance, and removes organic substances in the sewage-wastewater generated in the farming and fishing areas. It also relates to an integrated treatment system that combines aquatic hyacinth treatment paper with an oxidation paper that has an excellent effect on the removal of nutrients and pathogenic microorganisms.

이러한 본 발명은 하수/폐수처리에 있어서, 산화지의 전단과 후단에 수생히야신스 처리지를 설치하므로써 이루어진다.This invention is achieved by providing aquatic hyacinth treated paper at the front and rear ends of an oxidized paper in sewage / wastewater treatment.

도 1 은 현장 처리 실험을 통해 발명한 수생 히야신스 처리지(water hyacinth ponds, WHPs) 와 산화지 (waste stabilization ponds, WSPs) 를 결합한 농촌형 통합 하수-폐수 처리 공법의 공정을 도식적으로 나타낸 것이다.FIG. 1 schematically shows a process of a rural integrated sewage-wastewater treatment method combining water hyacinth ponds (WHPs) and waste paper (waste stabilization ponds, WSPs) invented through field treatment experiments.

도 2 는 상기한 통합 하수-폐수 처리시스템에 의해 수행한 하수처리 결과를 그래프로 나타낸 것이다.2 is a graph showing the sewage treatment results performed by the integrated sewage-wastewater treatment system.

본 발명의 하수/폐수처리는 도 1 에 도시된 바와 같이 수생 히야신스 처리조(2)를 거친 후 산화지(1)를 거치고 다시 수생 히야신스 처리조(3)를 거치도록 한 것으로, 하수/폐수처리에 기계적인 요소를 가급적 배제시켜 농어촌지역에서 큰 재정지원 없이 설치 가능하도록 한 것이다.The sewage / wastewater treatment of the present invention is to pass through the aquatic hyacinth treatment tank (2) and then go through the oxidized paper (1) and again to the aquatic hyacinth treatment tank (3), as shown in FIG. The mechanical element is eliminated as much as possible, so that it can be installed without significant financial support in rural areas.

농어촌 지역에서 발생되는 하수를 이용하여 처리실험을 수행한 결과 통합처리시스템을 구성하고 있는 각 공정은 아래와 같은 기능과 역할을 수행하는 것으로 밝혀졌다.(김영철, 김완중, 수질개선을 위한 수처리조 배열기법 연구 보고서, 1998, 1999, 농어촌 진흥공사, 농어촌 연구원)As a result of treatment experiments using sewage generated in rural areas, each process of the integrated treatment system was found to perform the following functions and roles (Kim Young-Chul, Kim Wan-Joong, Water Treatment Tank Arrangement Technique for Water Quality Improvement).

후속 수생히야신스 처리조(f-WHPs)(3)는 산화지로부터 유입되는 조류 및 기타 부유물질을 수생 히야신스의 뿌리를 이용하여 제거하기 위한 용도로 설치하였다. 운전기간을 통하여 유입수의 SS 농도는 산화지(1)에서 조류의 광합성 활동도(photosynthetic activities) 에 따라서 5-40 mg/L 까지 크게 변하였다. 이와 반면에 p-WHPs 유출수내의 SS 농도는 유입수의 농도에 관계없이 대부분 2-10 mg/L내외로 나타나 뿌리에 의한 SS 제거효율은 원래에 기대했던 기능과 역할측면에서 볼 때 매우 양호하였다.Subsequent aquatic hyacinth treatment tanks (f-WHPs) (3) were installed to remove algae and other suspended substances from the oxidized paper using the roots of aquatic hyacinth. Throughout the run, the SS concentration of the influent varied greatly from 5 to 4 mg / L depending on the photosynthetic activities of algae in the oxidized paper (1). On the other hand, the SS concentration in the p-WHPs effluent was about 2-10 mg / L regardless of the influent concentration, and the SS removal efficiency by roots was very good in terms of the functions and roles originally expected.

실시예 3Example 3

본 농촌형 통합 처리시스템에 의한 하수처리실험 결과 전체 수리학적 체류시간 10일에서 유입하수에 대하여 처리수질은 평균 SS 5mg/L, COD (크롬법) 20 mg/L, T-N은 1.6 mg/L, T-P는 0.2 mg/L 정도를 나타내었다.(도 2 참조)As a result of the sewage treatment experiment by the rural integrated treatment system, the treated water quality was average SS 5mg / L, COD (chromium method) 20 mg / L, TN 1.6 mg / L, TP Represents about 0.2 mg / L (see FIG. 2).

처리시스템의 안정성은 전체 운전기간의 80%에 해당하는 처리수질 농도(P80)와 10%에 해당하는 농도 P10의 비, 즉 P80/P10을 안정성 계수라 하는데, SS는 4.8, COD 4.0, T-N 15, T-P 3.0 으로 대단히 계절적 요인에 비추어 매우 양호하게 나타났다. 처리의 안정성은 동절기 동안에 처리 시스템의 온상화 또는 비닐하우스등에 의해 크게 향상시킬 것으로 판단된다.The stability of the treatment system is the ratio of the treated water quality concentration (P 80 ) corresponding to 80% of the total operation period and the concentration P 10 corresponding to 10%, that is, P 80 / P 10 , and SS is 4.8, COD 4.0, TN 15 and TP 3.0 were very good in light of seasonal factors. The stability of the treatment is expected to be greatly improved during the winter season by the warming up of the treatment system or the vinyl house.

본 발명은 농어촌 지역에 적합한 하수/폐수처리시스템에 관한 것으로, 재정적인 지원이 적은 실정에서 기계적인 요소를 가급적 배제시키고도 높은 처리효율을 얻을 수 있는 본 공법이 농어촌의 수질환경을 개선시키는데 효과적인 실효를 거둘 수 있을 것이다.The present invention relates to a sewage / wastewater treatment system suitable for farming and fishing areas, and this method is effective in improving the water quality of the farming and fishing villages, which can obtain high treatment efficiency even if there is little financial support.
