  • There are over 190,000 tons per year of the sludge containing heavy metals (SHM) generated from industries in Korea. The SHM is so hazardous waste, it needs proper intermediate treatment before final disposal. At present, the common intermediate treatment and final disposal technologies of SHM are solidification and landfill. However, the future treatment and disposal technologies of SHM will be carry out to fulfill in both the environmental aspect and resource recycling. Thus, how to reduce the generation of SHM and recycle the valuable metal from SHM become the major subjects in the global world. In this article, in order to prospect the effective processing of SHM, the generation and processing of the sludge from plating wastewater, the research and development of valuable metal recycling technology and problems were summarized.

  • The metal finishing industry generates a variety of pollutants such as acidic or alkaline wastewater, chromic compounds, cyanide, heavy metals, and toxic materials. Especially, zinc plating process is one of the processes which cause serious environmental problems. In this study, we applied the proven optimum technology to important unit processes in terms of implement effects through the process diagnosis and analysis. This study aimed to improve the working environment and the environmental pollutions in zinc plating process.

  • 환경오염이 심각해 질수록 수자원에 대하여, 생산공정에서 발생되는 폐수를 환경오염 기준치 이내로 처리후 단순 방류하는 소극적인 방법에서 보다 효과적이며 경제적인 처리 방법으로 개선하는 적극적인 인식의 전환을 요청받게 된다. 이것은 생산성에 직결되는 중요한 문제이며 기업의 경쟁력을 강화하는 조건이라 아니 할 수 없다. 더욱이 정부에서는 수자원의 고갈로 상수도 과다 수요업체를 대상으로 하는 오,폐수의 중수도화 정책을 시행할 예정이며, 세금및 상수도료 감면 혜택등으로 실질적인 상수도 절감을 유도하고 있으며, 금년 12월 부터 시행키로 발표된 바 있어, 이와 관련되는 기술의 관심이 그 어느때 보다 높아 지고 있다. 오,폐수 재사용의 기술은, 분류 처리 기술과 고도 처리 기술, 난분해성 폐수의 처리 기술로 크게 나누어 지는데, 당사가 반도체 도금 공장인 A 산업체에 적용한 분리막에 의한 난분해성 유기 용제 폐수의 처리 공법에 대한 연구 개발 실례를 소개하고자 한다.

  • We investigated the characteristics of heavy metal desorption and recovery from carbon foam after plating wastewater treatment. The heavy metal desorption depends on solution chemistry because desorption occurred in HCl and $H_2SO_4 $ solution but did not occur in distilled water. Heavy metal desorption efficiency was increased using ultrasonication with desorption solution. The higher ultrasonic power and the longer reaction time improve efficiency. The copper plating rinse solution was treated reliably by carbon foam adsorbent during 200 bed volume. The adsorbed copper was dissolved using desorption solution and recovered by DC power supply. After copper recovery, the reuse efficiency of desorption solution was 84.2%.
