천연중화제의 스크러버 타입의 탈취장치에 의한 암모니아 제거반응 특성 및 중화반응에의 산화반응의 관여여부에 대하여 연구하였다. 중화제 희석비 및 유입유량, 공기유량, 암모니아 초기 농도를 운전인자로 선정하여 이들이 암모니아 제거효율에 미치는 영향을 살펴본 결과, 중화제 희석비는 1.0%, 중화제 유입유량은 $60m{\ell}/min$이 적절하고, 암모니아 초기농도 및 공기유량에 대해서는 loading rate를 함께 고려하면 제거효율에 큰 영향성은 나타내지 않았다. 암모니아의 중화반응에 산화반응의 관여여부를 살펴본 결과, 암모니아의 아질산염 및 질산염으로의 산화반응이 확인되었으며, 중화제량이 증가할수록 그 산화반응의 진행정도도 증가함을 확인하였다. 즉, 중화제에 의한 흡수현상과 함께 부분적으로 산화반응이 관여함을 확인하였다.

Ammonia is an inorganic compound that may cause severe odor problem. In this study the effectiveness of applying natural neutralizer to destroy and remove the odor-causing compound from gas streams was studied. Experimental result evaluated with a bench-scale apparatus via the neutralization of gas phase. This indicates that the natural neutralization depends on the gas concentration, gas residence time, temperature and pH. Removal efficiency of ammonia from gas stream was achieved by 95% using theconvection in the packed bed. This study proved the chemical neutralization technology was effective for controlling inorganic odor-causing compound.

The earth environment consists of four spheres : geosphere, hydrosphere, atmosphere and biosphere. The geosphere consists mostly of minerals. It, however, contains some water and air in its shallow depth. Although hydrosphere and atmosphere consist predominantly of water and air, respectively, both contain some minerals. The biosphere consisting of various organisms is present in the interfaces of geosphere, hydrosphere and atmosphere. The natural environment of the earth is continuously changing by the interaction of four spheres. It suggests that out relevant environmental problems can not be revolved without understanding the natural relationship of these four spheres. Minerals in our environment are very important because they are the main constituent materials of the earth and they control our environment. The roles of minerals in our environment have not been understood even in the scientific society. Thus their roles have been neglected. Review of studies on the environmental mineralogy so far made at our laboratory and others show that minerals control the environment in various ways. Minerals neutralize the acid water as well as acid rain. Minerals in soils and rocks are major neutralizer of the acid rain. Salinization of sea water is attributed to the ionic substitution between minerals and sea water. Some minerals control the humidity of the air. Corals, the products of biomineralization, are the main carbon controller of the air. Minerals also adsorb heavy metals, organic pollutants and radioactive nuclides. Such remarkable functions for controlling the environment come from the mineral-water reaction and biomineralization. All these phenomena are subjects of the environmental mineralogy, a new field of earth science.
