Description

고농도 유기 물질 폐수 처리를 주제로 한 비료 및 사료의 제조 방법과 장치{The process of compost and forage from high concentration organic waste water}The process of compost and forage from high concentration organic waste water

통상 고농도 유기 물질 폐수는 BOD 10,000 ppm 이상의 폐수로서 일반적인 처리 방법으로는 1차 처리를 혼합 배양 계 호기성 미생물을 투입하여 활성 오니 처리하며 2차 처리는 물리 화학 처리로서 흡착, 응집, 침강 분리하고 있다.In general, high concentration organic wastewater is BOD 10,000 ppm or more. As a general treatment method, the primary treatment is mixed culture-based aerobic microorganisms and activated sludge treatment, and the secondary treatment is adsorption, flocculation and sedimentation separation as a physical chemical treatment.

상기 고농도 유기 물질 폐수 처리 방법으로는 희석수를 대량 사용하지 않으면 처리 불가하거나 완벽 처리는 기대할 수 없으며 설비 및 설치 면적이 커지고 이에 따라 시설 투자비의 과다, 운전의 불편과 오니의(sludge) 발생 량이 많고 동절기 저 수온 폐수 처리 문제가 심각하다.In the high concentration organic material wastewater treatment method, it is impossible to treat it without a large amount of dilution water, or complete treatment cannot be expected, and the facility and the installation area are large, and thus, the facility investment cost is excessive, the inconvenience of operation and sludge generation are large. Low temperature wastewater treatment in winter is a serious problem.

이런 고농도 유기 물질 폐수 처리하는 방법으로는 수질 오염 유발과 폐수 정화의 효율성과 활용성 등에 많은 문제점이 있었다.There have been many problems in the treatment of high concentration organic matter wastewater such as causing water pollution and efficiency and utilization of wastewater purification.

이와 같이 종래의 정화 방법으로는 악취 가스 정화 및 폐수 정화 효과는 크게 기대할 수 없어 보다 일신된 처리 방법으로 악취 및 처리 방법으로 특정 미생물 광합성 세균을 투입 처리하여 고농도 유기 물질 폐수를 액체 비료, 사료화 하고 저 농도 유기 물질 폐수는 1차 활성 오니 처리 후 2차 특정 미생물 클로렐라가 투입된 저수조의 자정 작용으로 정화 처리한 처리수는 농업, 축산업 용수로 사용할 수 있도록 한 것이다.In this way, the odor gas purification and wastewater purification effects cannot be greatly expected by the conventional purification method. Thus, the microorganism photosynthetic bacteria are injected into the odor and treatment method by a more advanced treatment method, and the high concentration organic matter wastewater is liquid fertilizer, feed and low Concentrated organic material wastewater is treated by the self-cleaning action of the reservoir where the second specific microorganism chlorella is injected after the first activated sludge treatment, so that the treated water can be used for agricultural and livestock industry water.

본 발명은 주로 각종 산업체에서 발생되고 있는 고농도 유기질 폐수 처리를 활성 오니로 처리하고 있는 문제점을 보완하여 액체 비료 및 사료를 생산하며 이를 농업 축산업 증산에 이용하고 잔여 미 처리된 처리수는 활성 오니의 처리와 클로렐라를 이용한 자정작용으로 최종 처리수를 농업 축산업 용수로 이용되어 하천의 오염 방지 및 자원을 이용하는데 목적이 있다.The present invention mainly compensates for the problem of treating high concentration organic wastewater generated by various industries with activated sludge to produce liquid fertilizer and feed, and use it for the agricultural livestock production, and the remaining untreated water is treated with activated sludge. The final treatment water is used as agricultural livestock water for the purpose of self-cleaning by using chlorella and chlorella.

본 발명은 축사, 도축장, 식품, 제약 기타 각 산업체에서 발생하고 있는 고농도 유기 물질 폐수에 특정 미생물인 광합성 세균을 투입하고 발효시키면 고품질의 아미노산 액체 비료와 사료를 생산 가공 가능하게 된다.The present invention is capable of producing and processing high-quality amino acid liquid fertilizers and feeds by injecting and fermenting photosynthetic bacteria, which are specific microorganisms, into high concentration organic matter wastewater generated in barns, slaughterhouses, food, pharmaceuticals and other industries.

이로서 종래에는 폐기 처분되던 유기물을 자원화 함으로서 폐수 처리 양이 대폭 감소된다.As a result, the amount of wastewater treatment is drastically reduced by recycling the organic materials that have been disposed of in the past.

또한 종래에는 고농도 유기질 폐수 처리 시 폐액을 희석시키기 위하여 추가의 희석 수가 필요하게 되어 시설의 용량이 커져 시설의 설치 면적도 추가로 필요하였으며, 유지 관리 비용도 증가하게 된다. 그러나 본 발명은 광합성 세균을 사용함으로 오니 량이 대폭 감소되어 지며 이를 발효 처리하여 자원화 함으로 얻는 효과는 상당히 기대되어 진다.In addition, conventionally, an additional dilution water is required to dilute the waste liquid during the treatment of the high concentration organic wastewater, thereby increasing the capacity of the facility, and additionally requiring the installation area of the facility, and increasing the maintenance cost. However, according to the present invention, the amount of sludge is greatly reduced by using photosynthetic bacteria, and the effect obtained by fermentation treatment and recycling is expected.

일부 미 처리된 폐수는 활성 오니 조에서 활성 오니 처리되어 지고 특정 미생물 클로렐라(Chlorella) 배양 저수 조로 유입되어 자정작용에 의해 최종 처리된 처리 수는 농업용, 축산용, 화장실 수세용, 세차장용, 기타 용수로 사용 할 수 있도록 한바 용수의 절감과 환경오염 방지 및 경제 절감의 기대 효과가 있다.Some untreated wastewater is treated from activated sludge tanks into activated sludge tanks and enters certain microbial Chlorella culture reservoirs, and the final treated water by self-cleaning is used for agriculture, animal husbandry, toilet washing, car wash, and other water. It is expected to save water and prevent environmental pollution and economic saving.
