Abstract:
본 발명의 표면이 개질된 활성탄의 제조방법 및 그 방법에 의해 제조된 표면이 개질된 활성탄은 비용 및 시간이 절감된 간단한 공정만으로 활성탄의 표면을 개질하여 유기오염물질이 포함된 폐수를 처리할 경우에 제거하기가 어려운 음이온성 오염물질을 제거할 수 있고, 그 외 오염물질이 제거 효율을 향상시킬 수 있다. 또한, 활성탄의 표면 개질을 통하여 활성탄의 오염물질 흡착능력을 향상시켜 높은 오염물질의 제거 효율을 가지는 활성탄을 제공할 수 있다.
Abstract:
PURPOSE: A method for determining leachat leakage at burial ground for livestock is provided to directly measure proteins, amines, peptides, amino acids, and ammonia and to quickly determine the leakage of the leachat. CONSTITUTION: A method for determining leachat leakage at burial ground for livestock to groundwater comprises: a step of measuring the concentration of livestock-derived materials from the groundwater; a step of measuring the concentration of total organic carbon; a step of calculating the concentration ratio of dead livestock-derived materials and total organic carbon; and a step of comparing the concentration ratio of the dead livestock-derived material with respect to the total organic carbon concentration with the concentration ratio of the dead livestock-derived materials with respect to the total organic carbon concentration of the leachat. [Reference numerals] (AA) Region 1 - underground water determined as contaminated leachat of livestock burial ground; (BB) Region 2 - uncontaminated underground water or surface water surrounding region; (CC) Region 3 - influent water of livestock waste water treatment plant; (DD) Livestock dead body-derived materials/total organic carbon; (EE) Region 1; (FF) Region 2; (GG) Region 3
Abstract:
PURPOSE: A removal method of a pathogenic microorganism or a toxicity organic contaminant using sulfate radical is provided to remove the pathogenic microorganism, and the toxicity organic contaminant or everyone is eliminated efficiently without the investigation of the excessive radiation. CONSTITUTION: A removal method of the pathogenic microorganism uses the radiation irradiation and sulfate radical are used at the same time. A removal method of the pathogenic microorganism is an object included in one selected from the group consisting of the foul water, the subsurface water, the polluted water environment, wastewater sludge, and the livestock excretion and food waste. The exposure of the radiation irradiation is absorbed in 1Gy~20 MGy.
