Description

슬러지 블록의 제조방법{sludge block}Sludge block manufacturing method {sludge block}

본 발명은 슬러지 블록의 제조방법에 관한 것으로, 상세하게는 상수도 처리과정에서 발생되는 슬러지 폐기물, 규장석 광물, 펄라이트, 접착제를 각각 40∼60 중량%, 20∼40 중량%, 5∼15 중량%, 5∼15 중량% 씩 혼합하고, 상기의 혼합물을 벽돌 블록이나 보도 블록으로 형성한 후 마이크로 웨이브 전기로에서 300℃ 이하의 온도로 소성하여 제조하도록 함으로써 슬러지 블록을 저가로 생산할 수 있으며, 경량화가 가능하도록 한 슬러지 블록의 제조방법에 관한 것이다.The present invention relates to a method for producing a sludge block, in particular 40 to 60% by weight, 20 to 40% by weight, 5 to 15% by weight of the sludge waste, quartzite mineral, pearlite, adhesive generated during the water treatment process , By mixing 5 to 15% by weight and forming the mixture into brick blocks or sidewalk blocks and firing them at a temperature of 300 ° C. or lower in a microwave electric furnace to produce sludge blocks at low cost and to reduce weight. It relates to a method for producing a sludge block.

일반적으로 한국에서 상수도 처리 후에 발생하는 폐기물은 30만톤 정도이고, 2007. 7월부터 환경국제협약에 의거 해양투기를 못하고 매립 또는 소각 또한 불가능한 실정은 것은 잘 알려진 사실이다.In general, it is well known that wastewater generated after water treatment in Korea is about 300,000 tons, and since July 2007, it is impossible to landfill or incinerate marine dumping under the International Convention on Environment.

그리고 하수종말처리장에서 배출되는 폐기물은 미생물처리 방식으로 하수처리된 것으로 유기물이 30%이상 함유되어 열원이 있어 일부 시멘트 생산공장에서 처리되고 있거나 막대한 정부자금이 투자되어 소각 탄화시키는 방법으로, 김해의 하수종말처리장에서 발생하는 1일 100톤의 폐기물을 처리하기 위한 시설을 위해 150억원을 투입하여 공사중이고, 2008년 준공예정이다.The waste discharged from the sewage terminal treatment plant is sewage treatment by microbial treatment method. It contains more than 30% of organic matter and has a heat source, so it is processed in some cement production plants or incinerated carbonization by investing huge government funds. It is under construction by investing 15 billion won for the facility to process 100 tons of waste a day generated from the terminal treatment plant.

하지만 상수도폐기물은 Al2O3가 30%이상, 유기물은 10% 미만 기타 중금속 5%미만과 참전물인 SiO2 등의 미네랄로 이루어져 열원이 없다.However, the waste water is composed of more than 30% of Al2O3, less than 10% of organic matter, and less than 5% of other heavy metals and minerals such as SiO2, a war veteran, and there is no heat source.

그러므로 상기의 폐기물을 소각하기 위하여는 순수하게 외부의 열원에 의해서만 소각이 가능하므로 막대한 비용이 소요되는 실정이다.Therefore, in order to incinerate the waste, since the incineration is possible only by an external heat source, the situation is enormous cost.

상수도를 관리하는 수자원공단에서는 매년 처리대책을 강구하기 위해 수십억원의 연구비를 지불하고 있지만, 효과적인 방법을 찾지 못하는 실정이다.The Water Corporation, which manages the waterworks, pays billions of research dollars each year to take treatment measures, but no effective way is found.

따라서 2006년 4월 13일자 특허출원 제10-2006-0033704호(슬러지의 처리방법)이 제안되었는 바,Therefore, Patent Application No. 10-2006-0033704 dated 13 April 2006 (sludge treatment method) was proposed.

이는, 필터프레스 등을 이용한 탈수 과정에 의하여 30 내지 70 중량%의 수분을 함유하게 된 슬러지를, 시멘트를 제조하는데 필요한 석회석, 점토, 규석, 철광석 등과 함께, 전체 원료의 0.5 내지 3중량% 범위에서 혼합하여 원료 분쇄기(mill)에 투입하였다.This is in the range of 0.5 to 3% by weight of the total raw material, along with limestone, clay, silica, iron ore, etc., which are required to prepare cement for the sludge containing 30 to 70% by weight of water by a dehydration process using a filter press or the like. The mixture was put into a raw mill.

상기의 원료 분쇄기는 예열기(preheater)에 의해 내부온도가 약 300℃로 유지되어 있으므로, 슬러지의 오염 성분인 탄화수소는 약 90% 이상 연소하여 이산화탄소 및 수증기로 변환된 후, 유인통풍기에 의해 백필터(bag filter)를 거쳐 외부로 배출되도록 하였다.Since the raw material pulverizer is maintained at about 300 ° C. by a preheater, hydrocarbons, which are the contaminants of the sludge, are burned by about 90% or more, converted into carbon dioxide and water vapor, and then bag filters ( bag filter) to be discharged to the outside.

상기의 원료 분쇄기에서 분쇄된 원료 혼합물은 원료 사일로(silo)를 거쳐 1300 내지 1500℃의 내부온도를 갖는 킬른(kiln)에서 25분가량 소성 과정을 거치게 되는데, 이 과정에서 원료 혼합물 중에 남아있던 슬러지의 탄화수소 성분이 완전 연소됨으로써 이산화탄소와 수증기로 배출된다. 그러므로, 슬러지는 TPH(Total Petroleum Hydrocarbon)와 같은 탄화수소 성분을 더 이상 포함하지 않게 되어, 시멘트의 부원료인 점토의 일부를 대체할 수 있도록 하였다.The raw material mixture pulverized in the raw material mill is subjected to a calcination process for about 25 minutes in a kiln having an internal temperature of 1300 to 1500 ° C. through a raw material silo, in which the sludge remaining in the raw material mixture is The complete combustion of the hydrocarbon component releases carbon dioxide and water vapor. Therefore, the sludge no longer contains a hydrocarbon component such as Total Petroleum Hydrocarbon (TPH), which makes it possible to replace a part of the clay which is a raw material of cement.

소성 결과 발생한 클링커(clinker)는 냉각기를 통과하여 냉각된 후 클링커 사일로(clinker silo)에 저장되며, 이후 시멘트 분쇄기(cement mill)에서 석고와 혼합되어 분쇄됨으로써 시멘트가 생성된다. 생성된 시멘트는 시멘트 사일로(cement silo)에 저장된 후 제품으로 출하되도록 하였다.The clinker generated as a result of firing is cooled by passing through a cooler and then stored in a clinker silo, and then mixed with gypsum in a cement mill to pulverize to produce cement. The resulting cement was stored in cement silos and then shipped to the product.

그러나 상기와 같은 종래의 슬러지의 처리방법에 의하여서는, 슬러지를 시멘트 생산 공장으로 운반하여야 하므로 운반이나 저장을 위한 시설이 많이 소요되는 단점이 있었다.However, according to the conventional method of treating sludge as described above, the sludge has to be transported to a cement production plant, which has a disadvantage in that a lot of facilities for transportation or storage are required.

이에 본 발명은 상기한 바와 같은 종래의 문제점을 해소시키기 위하여 안출된 것으로, 상수도 처리과정에서 발생되는 슬러지 폐기물, 규장석 광물, 펄라이트, 접착제를 각각 40∼60 중량%, 20∼40 중량%, 5∼15 중량%, 5∼15 중량% 씩 혼합하고, 상기의 혼합물을 벽돌 블록이나 보도 블록으로 형성한 후 마이크로 웨이브 전기로에서 300℃ 이하의 온도로 소성하여 제조하도록 함으로써 슬러지 블록을 저가로 생산할 수 있으며, 경량화가 가능하도록 한 슬러지 블록의 제조방법을 제공하는 것을 그 목적으로 한다.Accordingly, the present invention has been made to solve the conventional problems as described above, 40 to 60% by weight, 20 to 40% by weight, 5 to 40% by weight of sludge waste, quartzite mineral, pearlite, adhesive generated in the water treatment process, respectively 5 Sludge blocks can be produced at low cost by mixing 15-15% by weight and 5-15% by weight and forming the mixture into brick blocks or sidewalk blocks and then firing them at a temperature of 300 ° C. or below in a microwave electric furnace. It is an object of the present invention to provide a method for producing a sludge block capable of reducing weight.
