Abstract
Description
본 발명은 폴리우레탄 수지를 주제로 하여 다공질의 지올라이트, 활성탄 및 규조토 등을 적이 배합하여 폐수처리용 여과포를 제조하는 방법과 그 여과포에 관한 것이다.The present invention relates to a method for producing a filter cloth for waste water treatment by blending porous zeolite, activated carbon, diatomaceous earth and the like with a polyurethane resin as a subject, and the filter cloth.
종래에 폐수처리용 여과포로는 폴리에틸렌 수지나 폴리프로필렌 수지로 짠 직포를 사용하였으나 기공이 크고 성글어서 완전히 여과가 되지 못하여 실효를 거두지 못했을 뿐 아니라 특히 중금속이나 강산, 강알카리의 여과 흡착이 되지 않기 때문에 폐수정화에는 별도움이 되지 못한 폐단이 있었다.In the past, wastewater treatment cloth was used as a woven fabric made of polyethylene resin or polypropylene resin. Wastewater purification had no dispensation.
본원은 상기와 같은 폐수처러용 여과포의 폐단을 없애고 가장 효과적으로 거의 완벽한 폐수를 여과 및 정화하여 중금속이나 강산, 강알카리로 인한 수질 오염을 최대한 줄이기 위한 방법에 관한 것으로서 이를 실시예를 들어 상세히 설명하면 다음과 같다.The present application relates to a method for maximizing water pollution caused by heavy metals, strong acids, and strong alkalis by filtration and purifying a nearly perfect wastewater most effectively by eliminating the waste ends of the filter cloth for wastewater treatment, as described in detail below. Same as
본 발명은 물엿 상태의 습식 폴리우레탄 수지에 지올라이트, 활성탄 및 규조토 분말을 혼합한 것을 중간층으로 하고 폴리에틸렌이나 폴리프로필렌 섬유로 직조된 직포를 양면에 대고 유압으로 압착한 다음 일정시간 물에 침지하여 여과포를 완성하는 것으로 구성된다.The present invention is a mixture of zeolite, activated carbon and diatomaceous earth powder in the wet polyurethane resin in the state of starch syrup as an intermediate layer, and a woven fabric made of polyethylene or polypropylene fiber is pressed against both sides by hydraulic pressure and then immersed in water for a certain time. Consists of completing.
상기 본 발명에서, 각 구성성분은 적절히 변경 배합할 수 있으나 바람직하기는 지올라이트 5부, 활성탄 13부 및 규조토 5부에 대하여 습식 폴리우레탄 수지를 약 50부로 혼합하는 것이 바람직하다. 이때 지올라이트와 활성탄 및 규조토의 입자크기는 400∼600메쉬가 적절하며 상기 폴리우레탄 수지는 물엿 형태의 습식폴리우레탄 수지 즉 수분 약 65% 정도가 함유된 폴리우레탄 수지가 바람직하며, 상기 직포는 9합사 정도의직포가 적절하다. 상기에서 유압으로 압착시킨 여과포를 물에 침지하는 시간은 30분∼1시간 정도 침지시키면 된다.In the present invention, each component may be appropriately modified and blended, but it is preferable to mix the wet polyurethane resin to about 50 parts with respect to 5 parts of zeolite, 13 parts of activated carbon, and 5 parts of diatomaceous earth. In this case, the particle size of zeolite, activated carbon and diatomaceous earth is appropriately 400-600 mesh, and the polyurethane resin is preferably a wet polyurethane resin in the form of starch syrup, that is, a polyurethane resin containing about 65% of moisture. Plywood is appropriate. The time for immersing the filter cloth pressed by the hydraulic pressure in water may be immersed for 30 minutes-about 1 hour.
이상의 본원 발명에서 습식 폴리우레탄 수지와 지올라이트, 활성탄 및 규조토의 혼합물을 양면 직포와 함께 압착하지 않은채 경화시킬 경우 기공이 발생치 않거나 기공이 일정치 않아서 여과작용이 원활치 못하다.In the present invention, when the mixture of the wet polyurethane resin and zeolite, activated carbon, and diatomaceous earth is cured together with a double-sided woven fabric without porosity, no pores are generated or the pores are not uniform, so the filtration is not smooth.
또한 상기 지올라이트, 활성탄 및 규조토, 폴리우레탄 수지중 어느 하나만을 혼합했을 때에는 기공이 생기지 않거나 불균일하거나 또는 너무 크거나 너무 적어서 여과포로서 부적절하며, 상기 혼합물들을 이용치않고 직포로만 도금폐수 등을 여과했을 때는 직포가 부식되거나 심하게 오염되고 막히게 되어 여과포의 수명이 짧은 결점이 있었으나 상기 본원 발명의 물질들을 혼합한 혼합물을 사용하여 상기 방법과 같은 방법으로 만든 여과포를 가지고 도금폐수를 여과시에는 정밀하게 여과가 됨은 물론 중금속 및 산류를 여과하는 놀라운 효과가 있었다.In addition, when only one of the zeolite, activated carbon, diatomaceous earth, and polyurethane resin is mixed, pores are not formed or are uneven or too large or too small to be inappropriate as a filter cloth, and the plating waste water may be filtered through a woven fabric without using the mixture. When the woven fabric was corroded or severely contaminated and clogged, there was a short-lived defect of the filter cloth.However, when the plating wastewater was filtered with a filter cloth made by the same method using a mixture of the materials of the present invention, Of course, there was a surprising effect of filtering heavy metals and acids.
이상과 같이 지올라이트, 활성탄, 규조토 및 습식 폴리우레탄중 어느 한 가지나 선택적으로 사용시 보다 전체를 혼합 사용하므로 폴리우레탄 수지에 의하여 상기 혼합물중 여타 성분과 함께 직포와의 성형성을 좋게 할 뿐 아니라 상기 각각의 독특한 성분의 특성 때문에 그 독특한 성질들이 혼합되어 여과 효과가 상승되는 것이다. 즉, 상기한 바와 같이 여과 효과가 상승되는 이유로는 활성탄에 의한 정제효과, 일정성분의 포집, 회수, 탈색 등의 특성과 규조토에 의한 다공질성 및 지올라이트에 의한 다공질성과 이온교환성 등의 특성이 상호보완되고 폴리우레탄의 흡습성과 산류의 여과성이 합쳐진 결과라고 추정된다.As described above, since any one of zeolite, activated carbon, diatomaceous earth, and wet polyurethane is selectively used, the whole mixture is used, so that the polyurethane resin not only improves moldability with woven fabric together with other components in the mixture. Because of the unique constituents of, its unique properties are mixed to increase the filtration effect. That is, as described above, the filtration effect is increased due to characteristics such as purification effect by activated carbon, collection, recovery and decolorization of certain components, porosity by diatomaceous earth, porosity by zeolite and ion exchange property. Complementary, it is presumed to be the result of combining polyurethane hygroscopicity and acid filterability.
다시 말하면 상기와 같은 각 성분의 특성과 폴리우레탄 수지 및 직포에 의한 성형에 의하여 도금폐수를비롯한 각종 산업 폐수에 함유된 중금속류, 강산이나 강알카리류 및 염료 등을 여과, 탈색, 포집, 회수, 정제 및 이온교환하여 폐수를 여과 정제하는 것으로 추정된다. 뿐만 아니라 본원에서는 상기 각 혼합성분들이 가공성이 모두 상이하기 때문에 즉 기공의 크기가 다르기 때문에 이들 성분들이 조합되므로서 여과포의 기공을 균일하게 다양화할 수 있는 특징도 있다고 본다.In other words, by filtering, decolorizing, collecting, recovering, and purifying heavy metals, strong acids, strong alkalis and dyes contained in various industrial wastewaters including plating wastewater by the characteristics of each component and molding by polyurethane resin and woven fabric. And ion exchange to filter the wastewater. In addition, in the present application, since each of the mixed components are all different in processability, that is, because the size of the pores is different, these components are combined, so that the pores of the filter cloth can be uniformly diversified.
이상과 같은 본원 발명의 여과포는 크롬, 망간 등을 함유한 도금 공장의 중금속 폐수까지도 거의 완멱하게 여과 포집하여 중금속을 흡착 여과할 뿐 아니라 기타 화학약품 처리공정 폐수중의 강산이나 알카리까지도 흡착, 중화 또는 이온교환하는 성질이 있어서 공업용 폐수 여과처리에 매우 유용한 발명이라고 하겠다.As described above, the filter cloth of the present invention almost completely filters and collects heavy metal wastewater of a plating plant containing chromium, manganese, and the like, and adsorbs and neutralizes heavy metals, and also adsorbs, neutralizes or neutralizes strong acids or alkalis in the wastewater of other chemical treatment processes. It is said to be a very useful invention for industrial wastewater filtration because of its ion exchange properties.
