Description

고염도 폐수의 전기화학적 처리장치{Apparatus for treating high salinity waste water}Apparatus for treating high salinity waste water

본 발명은 고염도 폐수처리시 문제가 되는 고농도의 염분을 효율적으로 제거하고, 수산화나트륨을 에폭시 제조시 사용되는 촉매제로 재활용할 수 있는 등 폐수 처리비용을 대폭 절감시킬 수 있는 고염도 폐수의 전기화학적 처리장치에 관한 것이다.
The present invention can efficiently remove high concentrations of salts, which are a problem when treating high salt wastewater, and recycle sodium hydroxide as a catalyst used in the manufacture of epoxy. It relates to a processing apparatus.

일반적인 에폭시수지 제품을 제조하는 공정에서 발생되는 폐수에는 약 20%이상의 NaCl을 함유하고 있다. 이는 원료인 에피클로로히드린(E.C.H)에 의하여 발생되는 염화이온과 공정 중 촉매제로 사용되는 NaOH에 의해 생성된다. 따라서 폐수 처리 시 고 염도의 원 폐수를 공업용수를 이용 희석하여 처리하고 있으며 처리효율 및 비용 등의 여러 가지 문제점을 가지고 있다.Wastewater from the process of manufacturing general epoxy resin products contains more than about 20% NaCl. It is produced by chloride ions generated by epichlorohydrin (E.C.H) as a raw material and by NaOH used as a catalyst in the process. Therefore, raw wastewater with high salinity is treated by dilution with industrial water during wastewater treatment and has various problems such as treatment efficiency and cost.

에폭시수지 제조공정 등에서 생성되는 고염도 폐수는 폐수처리 시 원 폐수를 공업용수로 희석하는 비교적 처리비용이 큰 방법을 이용하고 있다. 이러한 처리법은 유기부산물의 분해미생물의 활성이 감소되고 처리효율의 급감, 사상균발생 등의 여러 가지 문제점을 야기한다.
The high salinity wastewater produced in the epoxy resin manufacturing process uses a relatively expensive process of diluting the raw wastewater with industrial water during wastewater treatment. Such treatment reduces the activity of the decomposed microorganisms of organic by-products, and causes various problems such as rapid decrease in treatment efficiency and the occurrence of filamentous fungi.

현재 국내 액상 에폭시 제조공정 중 폐기물로 NaCl 과 폴리머 및 기타 COD 물질들이 발생하게 된다. 이들 폐기물을 처리하는 방법으로 대부분 폐수처리 공정에서 회수하여 폐기하거나 희석하여 처리 후 방류하는 방법을 사용하고 있다. 따라서 폐기물의 배출을 줄이기 위해서는 후처리에 의해 자원을 회수 재활용 하거나 근본적으로 제조공정 중에서 폐기물의 발생을 감소시키는 방법 개발이 바람직하다. 대부분 에폭시 제조업체에서는 현재 공정 개선을 통한 생산원가 및 폐기물 발생량을 감소시키기 위한 기술 개발에 힘쓰고 있다. 금호 피엔피 화학에서는 2005년 자사 에폭시 생산공정의 청정생산 진단 지도란 연구 과제를 수행하고 이를 통해 생산 공정 중 개선안을 도출하여 적용하고 있다. 하지만 공정개선을 통한 방법에는 근본적인 한계가 존재한다.
Currently, NaCl, polymers and other COD materials are generated as waste during the domestic liquid epoxy manufacturing process. As a method of treating these wastes, most of them are recovered and disposed of in a wastewater treatment process, or are diluted and discharged after treatment. Therefore, in order to reduce the discharge of waste, it is desirable to develop a method of recovering and recycling the resources by post-treatment or essentially reducing the generation of waste in the manufacturing process. Most epoxy manufacturers are currently working to develop technologies to reduce production costs and waste generation through process improvements. In 2005, Kumho P & P Chemistry carried out a research project called Clean Production Diagnosis Guidance for Epoxy's Epoxy Production Process. However, there are fundamental limitations to the method through process improvement.

국외 에폭시 산업체에서도 공정개선을 통해 폐기물 발생을 감소시키기 위한 기술 개발이 많이 이루어지고 있으며 대표적으로 Dow는 재생가능한 원료를 사용하고 폐수발생량을 70%이상 줄일 수 있는 새로운 에폭시 수지 생산 공정을 개발하였다.
Overseas epoxy industry has been developing a lot of technology to reduce waste generation through process improvement. Representatively, Dow has developed a new epoxy resin production process that uses renewable raw materials and can reduce waste water generation by more than 70%.

본 발명은 고염도 폐수처리시 문제가 되는 고농도의 염분을 효율적으로 제거하고, 수산화나트륨을 에폭시 제조시 사용되는 촉매제로 재활용할 수 있는 등 폐수 처리비용이 저렴하고 폐수처리시 발생되는 부산물을 재활용할 수 있는 고염도 폐수의 전기화학적 처리장치를 제공함에 그 목적이 있다.
