CaO₂를 투입한 연안퇴적물의 환경변화 연구

초록

We investigated the changes in a contaminated bay sediment when some oxygen releasing compounds (ORC) were put in it: it was found that the ORCs such as MgO2, CaO2, and Mg(OH)2 were good at suppression of H2S and removal of phosphorus by changing the neutral pH into weak alkaline pH. In particular, performance of CaO2 was the best of all probably because of the faster establishment in O2 generation and weak alkaline condition. Consequently, it was concluded that ORCs instead of sea cultivation or red clay spreading would promote the conditions better in which O2 should kept being generated and active microbial population for bioremediation should be maximized.
