본 발명은 다공성 미세조류 비드를 포함하는 수질 정화기에 관한 것으로, 보다 상세하게는 본 발명의 다공성 미세조류 비드를 포함하는 수질 정화기는 미세조류를 다공성 고분자 지지체에 담지하여 다공성 미세조류 비드를 형성한 후 상기 다공성 미세조류 비드의 표면을 생분해성 고분자로 코팅하여 이를 수질 정화기에 적용함으로서 상기 다공성 미세조류 비드의 회수가 용이하며, 경쟁적 억제 효과로 미세조류가 과하게 증식하는 것을 제어할 수 있다. 또한 수질 내 질산염, 인산염 및 중금속 등을 효과적으로 제거하고 산소를 공급하여 수질 악화를 방지하는 동시에 녹조 발생을 예방할 수 있다. 또한 비드 형태로 이루어져 있어 수조 내 심미성을 향상시킬 수 있다. 본 발명은 한국환경산업기술원(환경부)의 24 에코스타트업 지원사업 창업기업 부문(B0080429001978) "지능형 DX_bead 미세조류를 이용한 실내 공기질 개선용 공기청정기 개발(주관기관: ㈜휴에버그린팜, 연구기간: 2024. 04. 08. ~ 2024. 09. 30. (약 6개월))"을 통해 개발된 기술이다.
