Abstract

질소 및 인이 함유되어 있는 폐수의 처리에 있어서, 바닷물을 이용하여 상기 질소 및 인을 스트루바이트(struvite) 및 히드록시에퍼타이트(hydroxyapatite)로 결정화하여 제거하는 방법을 개시한다. 이는 비용이 많이 드는 화학약품인 Ca(OH), 및 MgCl2를 사용하는 대신에 바닷물 또는 간수에 함유되어 있는 Mg++와 Ca++성분을 이용하여 폐수중의 질소와 인을 결정화시켜 제거하는 것으로서, 비용이 매우 저렴할 뿐만 아니라, 이들의 제거 효율도 매우 높다.In the treatment of wastewater containing nitrogen and phosphorus, a method of crystallizing and removing the nitrogen and phosphorus by struvite and hydroxyapatite using seawater is disclosed. Instead of using expensive chemicals such as Ca (OH) and MgCl 2 , it removes the crystallization of nitrogen and phosphorus in wastewater by using Mg ++ and Ca ++ components contained in seawater or brine. As well as being very inexpensive, their removal efficiency is also very high.
