Description

정.하수오니 슬러지를 이용한 퇴비화 제조방법{method for manufacturing compost by using sewage sluge}Method for manufacturing compost by using sewage sluge

본 발명은 폐기물인 오니 및 슬러지 처리방법에 관한 것으로, 더욱 상세하게는 하수종말처리장에서 1차 하수처리 후 필연적으로 발생되는 오니 및 슬러지를 처리하여 유익한 비료를 제조하여 자원재활용 및 환경오염방지가 가능하도록 하는 정.하수오니 슬러지를 이용한 퇴비화 제조방법에 관한 것이다.The present invention relates to a waste sludge and sludge treatment method, and more particularly, by treating the sludge and sludge which is inevitably generated after the first sewage treatment in the sewage treatment plant to produce a beneficial fertilizer, it is possible to recycle resources and prevent environmental pollution. It relates to a composting manufacturing method using the sewage sludge.

일반적으로 일상생활에서 발생되는 오,페수 및 음식물쓰레기 등을 처리하고 있는 하수종말처리장에서는 1차로 상기 폐기물을 처리한 후에는 많은 양의 오니 및 슬러지가 생성된다. 이러한 오니 및 슬러지(이하에서는 통칭하여 슬러지라 부르기로 한다.)는 각종 유기물 및 무기산 등의 무기물이 다량함유되어 있음에도 불구하고 이를 이용하지 못하고 압축 등의 방법에 의해 부피를 줄임과 동시에 약간의 수분을 제거한 상태에서 매립하는 것이 일반적인 처리방법이었다.In general, a sewage terminal treatment plant that treats wastewater, wastewater and food waste generated in daily life generates a large amount of sludge and sludge after treating the wastes first. These sludges and sludges (hereinafter referred to collectively as sludges) are not used even though they contain a large amount of various organic substances and inorganic acids. Landfill while removed was a common treatment.

그러나, 상기 슬러지를 그대로 매립하는 경우에는 과도한 매립비용이 발생할 뿐만 아니라 매립장소가 한계에 부딪치는 문제점이 있다. 또한 그리고, 상기 매립된 슬러지에서 발생되는 침출수로 인하여 강이나 하천등에 녹조 및 적조를 유발하여 환경오염을 야기시키는 문제점이 발생한다. 이러한 문제점으로 인하여 2002년부터는 이러한 슬러지를 매립장내에 직매립하는 것이 금지되도록 현재 입법예고되었다.However, when the sludge is buried as it is, not only excessive landfill costs are incurred, but also a landfill site has a problem of hitting a limit. In addition, the leachate generated from the buried sludge causes a problem of causing environmental pollution by causing green algae and red tide in rivers or rivers. Due to these problems, legislation has been announced in 2002 to prohibit the landfilling of such sludge directly in landfills.

이러한 매립의 문제점을 해결하기 위해 상기 슬러지를 소각하는 방법이 제안되고 있으나, 상기 슬러지의 소각 역시 여러가지 문제점을 내포하고 있다. 즉, 소각을 위해서는 소각로의 설치가 필요하며, 이를 위해서는 과도한 투자설비가 따라야한다. 그리고, 이러한 소각에 의해 발생되는 분진 등은 대기오염을 야기시킬 뿐만 아니라 주거환경에 영향을 끼쳐 민원발생을 야기시키는 문제점이 있다.In order to solve the problem of landfill, a method of incineration of the sludge has been proposed, but incineration of the sludge also includes various problems. In other words, incineration requires the installation of incinerators, which requires excessive investment. In addition, dust generated by incineration not only causes air pollution, but also affects the residential environment and causes civil complaints.

또한, 상기 소각에 의해 발생되는 맹독성가스 및 다이옥신은 인체에 치명적인 영향을 끼치므로 이러한 유해물질의 배출을 막기 위해서는 별도의 2차오염방지시설을 갖추어야함으로 과도한 비용발생을 야기시키는 문제점이 있다.In addition, since the toxic gas and dioxin generated by the incineration have a fatal effect on the human body, in order to prevent the discharge of these harmful substances, a separate secondary pollution prevention facility should be provided to cause excessive cost generation.

따라서 본 발명은 상기의 문제점을 해결하기 위한 것으로, 유기물과 유기물이 풍부한 오니 및 슬러지를 별도의 제조장치없이 간단하게 처리하여 퇴비로 활용함으로써 자원의 재활용을 유도하고, 별도의 환경오염을 야기시키지 않는 정.하수오니 및 슬러지를 이용한 퇴비화 제조방법을 제공하는데 그 목적이 있다.Therefore, the present invention is to solve the above problems, by simply treating the organic and organic-rich sludge and sludge as a compost without a separate manufacturing device to induce the recycling of resources, does not cause a separate environmental pollution An object of the present invention is to provide a method for preparing compost using sewage sludge and sludge.

또한, 본 발명은 토양을 산성에서 알카리성으로 개질시키는 토양개질제로서의 역활뿐만 아니라 토양을 개량하여 화학비료나 농약에 의한 토양변질을 저지하는 퇴비활용용도와, 시멘트원료로도 사용 가능한 오니 및 슬러지의 자원재활용을 도모하는 폐기물활용 방법을 제공하는데 다른 목적이 있다.In addition, the present invention not only serves as a soil modifier for reforming the soil from acidic to alkaline, but also improves the soil to prevent soil deterioration by chemical fertilizers or pesticides, and the resources of sludge and sludge that can be used as cement raw materials. Another purpose is to provide a waste utilization method for recycling.

상기와 같은 목적을 달성하기 위한 본 발명은, 수집된 오니 및 슬러지와 분말로된 산화칼슘(CaO)을 1:0.1-10 중량비율로 혼합하고, 0.1-0.25시간 동안 산화소석 과정을 거치면서 150-400℃ 온도로 간접가열시키는 제1과정과; 상기 제1과정을 거친 혼합물에 칼슘설파이트(CaS)를 1:0.1-10중량비율로 혼합하고, 상기 혼합물을 교반기에서 0.1-0.25시간동안 교반시켜 함수율이 30%이하가 되도록 하는 제2과정과; 상기 혼합물에 일나이트(illnite)와 게르마늄중 어느하나와 황토성분을 1:0.1-10 중량비율로 혼합하여 2-5mm의 입지형성을 하고 건조시켜 고화시키는 제3과정;으로 구성되는 정,하수오니 및 슬러지를 이용한 퇴비화 제조방법을 제공하는데 기술적 요지가 있다.In order to achieve the above object, the present invention, the collected sludge and sludge and powdered calcium oxide (CaO) in a ratio of 1: 0.1-10 by weight, and passed through the process of calcination for 0.1-0.25 hours 150 Indirect heating to a temperature of -400 ° C .; Mixing calcium sulfite (CaS) in a 1: 0.1-10 weight ratio to the mixture that passed through the first process, and the second process of stirring the mixture for 0.1-0.25 hours in a stirrer so that the water content is less than 30% and ; The third process of mixing any one of illite and germanium and the ocher component in a weight ratio of 1: 0.1-10 to form a location of 2-5mm, drying and solidifying the mixture; And it has a technical point to provide a method for producing compost using sludge.

따라서 오니 및 슬러지를 환경오염을 야기하지 않은채 간단하게 퇴비로 사용가능함에 따라 자원재활용은 물론 토양개량제로 사용될 수 있는 잇점이 있다.Therefore, sludge and sludge can be used as a simple compost without causing environmental pollution, there is an advantage that can be used as a resource improver as well as a soil recycling.

다음, 본 발명에 의한 정.하수오니 및 슬러지를 이용한 퇴비화 제조방법을 보다 상세하게 설명하기로 한다.Next, the composting method using the purified sewage sludge and sludge according to the present invention will be described in more detail.

제1 실시예First embodiment

1과정 : 먼저, 수집된 오니 및 슬러지와 분말로된 산화칼슘(CaO)을 1:0.1-10 중량비율로 혼합하고, 0.1-0.25시간 동안 산화소석 과정을 거치면서 150-400℃ 온도로 간접가열시킨다.Step 1: First, the collected sludge and sludge and powdered calcium oxide (CaO) were mixed at a weight ratio of 1: 0.1-10, and indirectly heated to 150-400 ° C. while undergoing a calcination process for 0.1-0.25 hours. Let's do it.

오니 및 슬러지는 각종 음식물쓰레기에서 생성되므로 자체내에 유기질함량이 풍부할 뿐만 아니라 각종 토양에 유익한 산화마그네슘(MgO), 인(P)등의 무기물이 풍부하여 비효(肥效)가 높아 비료로 사용시에 아주 유익하다. 또한 이러한 자연성 항유물은 보비력, 보수력 통기성이 좋아 식물성장에 아주 유익한 효과가 있다. 그러나, 이러한 유기물은 탄소율(C/N)이 높은 물성때문에 부숙이 느린 단점이 있을 뿐만 아니라 자체에 많은 수분이 함유되어 있어 짧은 시간내에 부숙이 잘이루어지지 않게 된다. 따라서 소정온도로 간접가열함에 따라 자체내에 함유된 수분을 증발시키게 될 뿐만 아니라 유해물질의 살균 및 악취제거가 이루어질 수 있게된다. 한편, 간접가열방식을 택하는 이유는 직접가열방식을 채용할 경우, 상기 열에 의해 슬러지내에 함유된 유기물이 탄화되어 영양분의 손실이 발생되기 때문이다.Sludge and sludge are produced from various food wastes, so they are not only rich in organic content but also rich in minerals such as magnesium oxide (MgO) and phosphorus (P), which are beneficial to various soils. helpful. In addition, the natural anti-relics have a very beneficial effect on plant growth because of its good retention and breathability. However, these organic materials not only have a disadvantage of slow housing due to high physical properties of carbon (C / N), but also contain a lot of moisture, so that the organic matter cannot be easily grown within a short time. Therefore, indirect heating to a predetermined temperature not only evaporates the moisture contained in itself, but also enables sterilization and odor removal of harmful substances. On the other hand, the reason for choosing the indirect heating method is that when the direct heating method is adopted, the organic matter contained in the sludge is carbonized by the heat and loss of nutrients occurs.

그리고, 산화칼슘을 섞는 이유는 퇴비로 사용될 경우 토양의 개질을 이루기 위함이다. 즉, 산화칼슘(CaO)은 1960년대 후반 토양개량제로 보급되어 생산증대화 사업을 위해 농촌에 널리 보급되었으나, 화학비료의 등장으로 유기농법이 점차사라짐에 따라 거의 사용되지 않았다. 이러한 화학비료의 사용으로 현재 많은 토양이 산성화되어 가고 있으므로 이러한 산성화를 방지하기 위해 산화칼슘을 첨가해주게 된다. 또한, 이러한 산화칼슘은 본 발명에 의해 처리된 슬러지가 시멘트원료로 사용될 경우 충분한 접착력을 가질 수 있도록 하는 이중의 역활을 하게된다.And, the reason for mixing the calcium oxide is to achieve the reform of the soil when used as compost. In other words, calcium oxide (CaO) was widely used in rural areas for production enhancement projects in the late 1960s, but was rarely used as organic methods gradually disappeared due to the emergence of chemical fertilizers. Since many soils are being acidified by the use of such chemical fertilizers, calcium oxide is added to prevent such acidification. In addition, such calcium oxide has a dual role of allowing the sludge treated by the present invention to have sufficient adhesion when used as a cement raw material.

제2과정 : 상기 제1과정을 거친 혼합물에 칼슘설파이트(CaS)를 1:0.1-10중량비율로 혼합하고, 상기 혼합물을 교반기에서 0.1-0.25시간동안 교반시켜 함수율이 30%이하가 되도록 한다.Second Step: Mix the calcium sulfite (CaS) at a ratio of 1: 0.1-10% by weight to the mixture which passed the first step, and stir the mixture for 0.1-0.25 hours in a stirrer so that the moisture content is 30% or less. .

제1과정을 거치는 동안 어느정도 수분이 제거된 슬러지혼합물은 여전히 높은 함수율을 지니고 있다. 이 상태에서 그대로 퇴비로 사용할 경우에는 침출수의 유출뿐만 아니라 상기 수분에 의한 미생물의 발아에 따른 악취가 발생하게 된다. 또한, 시멘트원료로 사용되기 위해서는 시멘트제조를 위해 필요로하는 큐베(30mm이하)함수율이 30%이하이어야 한다. 따라서 고상의 분말형태인 칼슘설파이트를 넣고 골고루 교반함으로써 전체의 함수율이 30%이하가 되도록 한다.The sludge mixture, which has been somewhat dehydrated during the first stage, still has a high water content. In this state, when used as a compost as it is, not only the outflow of leachate, but also the odor caused by the germination of the microorganisms by the water. In addition, in order to be used as a cement raw material, Cube (less than 30mm) water content required for cement production should be less than 30%. Therefore, the calcium sulfite in the form of a solid powder is added and stirred evenly so that the total moisture content is 30% or less.

또한, 이러한 물질로 칼슘설파이트를 사용하는 이유는 두가지 측면에서 이다. 첫째, 퇴비화를 위해서는 토양의 알카리성을 유도하는 물질이어야 하며, 또한 토양에서 비료로 충분히 작용할 수 있다는 것이다. 즉, 칼슘설파이트 자체가 알카리성 물질이며, 또한, 상기 설파이트는 토양에서 식물의 생육에 부족하기 쉬운 황성분을 보충해주므로 아주 유용한 성분이다. 둘째, 시멘트원료로 사용되기 위해서는 충분히 반응성이 풍부하여야 한다. 즉, 상기 칼슘성분은 시멘트원료를 이루는 석회석의 일부분을 이루므로 아주 유용한 물질이다. 따라서 상기 함수율을 유지하기 위해 칼슘설파이트의 사용은 아주 바람직한 물질이다.In addition, the reason for using calcium sulfite as such material is in two aspects. First, in order to compost, it must be a substance that induces alkalinity of the soil, and can also function sufficiently as a fertilizer in the soil. That is, calcium sulfite itself is an alkaline substance, and the sulfite is a very useful ingredient because it supplements a sulfur component which is likely to be insufficient for plant growth in soil. Second, in order to be used as a cement raw material, it must be sufficiently reactive. That is, the calcium component is a very useful material because it forms part of the limestone constituting the cement raw material. Therefore, the use of calcium sulfite to maintain the moisture content is a very preferred material.

3과정 : 상기 혼합물에 일나이트(illnite)와 게르마늄중 어느하나와 황토성분을 1:0.1-10 중량비율로 혼합하여 2-5mm의 입지형성을 하고 건조시킨다.Step 3: Mix one of illite and germanium with ocher in a ratio of 1: 0.1-10 by weight to form a 2-5 mm position and dry the mixture.

상기 제3과정은 퇴비로서의 가치를 더욱 더 증대하기 위해서이다. 즉, 상기 퇴비가 뿌려지는 토양을 비옥하게 만들어 식물의 생육을 보다 좋게 하기 위해서이다. 즉, 상기 일나이트,게르마늄 또는 황토의 성분중에는 SiO2,Al2O3가 함유되어 있으므로 토양의 성분을 개질할 수 있을뿐만 아니라 Na2O, K2O, CaO, MgO 등의 금속산화물이 함유되어 있으므로 산성화된 토양을 알카리성으로 바꾸어 토양자체를 비옥하게 할 수 있다. 그리고, 상기 과정중에 일정한 크기로 제조됨은 물론 건조과정에 의해 쓰레기 자체내에 함유된 수분이 완전제거되므로 토양에 뿌려지기전 보관중에는 미생물의 발아에 의한 부식으로 악취발생이 저지되고, 별도 보관이 가능해짐은 물론 필요시마다 사용할 수 있게 된다.The third step is to further increase the value as compost. That is, to fertilize the soil to which the compost is sown, so as to improve the growth of plants. That is, since the illite, germanium, or loess contains SiO 2 , Al 2 O 3 , not only can the soil be modified, but also metal oxides such as Na 2 O, K 2 O, CaO, and MgO are contained. As a result, the acidified soil can be converted to alkaline to fertilize the soil itself. In addition, since the moisture contained in the waste itself is completely removed by the drying process as well as being produced in a predetermined size during the process, odor generation is prevented due to corrosion by germination of microorganisms during storage before being sprayed on soil, and it is possible to store separately. Of course you can use it whenever you need

따라서 상기와 같은 구성으로 이루어지는 혼합물을 비료로 사용시에는 쓰레기 자체에 함유된 유익한 유기물이 토양자체에서 부식되어 거름으로서의 역활과 상기 첨가물에 의해 토양이 알카리성으로 개질됨에 따라 식물성장촉진 뿐만 아니라 환경오염의 방지가 이루어지게 된다. 또한 본 발명에 의한 오니 및 슬러지 자원화방법은 처리시설투자가 소각시설에 비해 약 1/3 밖에 들지않고 슬러지의 전량 재활용이 가능하며, 이러한 시설 건설시 오염야기가 발생하지 않으므로 민원발생의 소지가 전혀없어 시설설치지역에 제한이 없게 된다.Therefore, when using the mixture of the above composition as a fertilizer, the beneficial organic matter contained in the waste itself is corroded in the soil itself, and as the manure is modified by the additives, the soil is alkalinely modified, thereby preventing plant pollution and preventing environmental pollution. Will be made. In addition, the sludge and sludge resource recycling method according to the present invention is capable of recycling the total amount of sludge, and the treatment facility investment is only about one third of that of the incineration facility, and no pollution occurrence occurs in the construction of such facilities. There is no restriction in the facility installation area.

제2실시예Second embodiment

상기 제1실시예에서는 비료로 사용하기 위한 쓰레기처리방법이었으나, 본 실시예서는 시멘트원료로 사용하기 위한 방법이다. 즉, 상기 오니 및 슬러지에 1,23과정동안 가해지는 첨가물에 의해 시멘트회사에서 요구하는 큐베 함수율이 30%이하가 가능하며, 또한 시멘트에 혼합되어 경화후에는 단단한 경도를 유지할 수 있으므로 처리되는 양에 따라 시멘트원료로서의 활용이 가능하다.In the first embodiment was a waste disposal method for use as a fertilizer, this embodiment is a method for use as a cement raw material. That is, by the additives applied to the sludge and sludge during the 1,23 process, the Cubic water content required by the cement company can be less than 30%, and also mixed with cement, so that the hardness can be maintained after curing, so Therefore, it can be used as a cement raw material.

이상에서 설명한 바와 같이, 본 발명에 따르면, 하수종말처리에 의해 발생되는 오니 및 슬러지를 별도의 고가장치없이 환경오염을 야기하지 않으면서 퇴비로서 재활용함으로써 자원재활용을 달성하는 효과가 있다.As described above, according to the present invention, there is an effect of recycling the sludge and sludge generated by the sewage terminal treatment as compost without causing an environmental pollution without a separate expensive device.

그리고, 상기 오니 및 슬러지에 함유된 성분들에 의해 질좋고 산성토양을 알카리성 토양으로 변화시킴에 따라 이러한 퇴비가 주어진 토양하에서 자란 식물들의 수확량이 증대에 의한 경제적이익 창출은 물론 토양의 개량에 의해 환경보전이 이루어지는 다른 효과가 있다.In addition, by changing the quality and acidic soils into alkaline soils by the components contained in the sludge and sludge, economic benefits are generated by increasing the yield of plants grown under the composted soil as well as by improving the environment. There is another effect of conservation.

또한, 상기 오니 및 슬러지 처리물을 시멘트원료로 사용가능함에 따라 별도의 자원으로 활용가능한 잇점이 있다.In addition, as the sludge and sludge treatment can be used as a cement raw material, there is an advantage that can be utilized as a separate resource.
