Sewage and Tissue Wastewater Treatment Using Quartz Porphyry and Natural Zeolite

In this study, not only making an effort to find a solution for sewage and wastewater treatment, but also demonstrating a feasibility of wastewater disposal process which is treated with the cohesion and adsorption mechanism of sewage and wastewater using quartz porphyry and zeolite, which is a domestic natural resource. By using a jar test, we evaluated removal efficiency of $COD_{Cr}$ after reation. According to the result of experiment, when we injected 400~1,200 g/L of quartz porphyry and zeolite into a sewage as a coagulant, there was no difference of the rejection rates of $COD_{Cr}$, however, when quartz porphyry and zeolite, which were sintered at $600^{\circ}C$, were treated into urban sewage, removal efficiency of $COD_{Cr}$ had increased by about 15%, 3% respectively. In addition, we applied into a cosmetic tissue wastewater by using mixture of quartz porphyry and natural zeolite in order to analyze the applicability of other wastewater as well as Municipal Sewage.

맥반석과 천연제올라이트를 이용한 도시하수와 화장지폐수처리

본 연구에서는 오 폐수의 처리에 있어서 천연제올라이트 및 맥반석을 활용하여 오 폐수의 응집 및 흡착 메커니즘에 적용하여 수처리제로서의 타당성을 검토하고자 하였다. Jar test를 이용한 응집 전 후의 $COD_{Cr}$의 제거율을 평가하였다. 맥반석과 천연제올라이트를 수처리제로써 주입량을 400~1,200 g/L로 변화시켜 처리한 결과 $COD_{Cr}$ 최종제거율은 별 차이를 보이지 않았으나, 맥반석과 천연제올라이트를 $600^{\circ}C$로 소결하여서 도시하수를 처리할 경우 $COD_{Cr}$제거율이 각각 15%, 3%정도 상승하였다. 또한 맥반석과 천연제올라이트를 혼합하여 미용화장지 폐수처리에 적용하였으며, 또 다른 폐수처리제로서의 가능성을 검토하였다.
