Abstract: 본 발명은 돈분뇨수처리방법에 관한 것이다.통상의 적게는 수백내지 수만돈을 기르는 축산농가에서는 매일 수십톤의 돈분과 뇨를 처리하는 것이 매우 큰 문제 현재까지 적당한 정화방법이 없이,이들 농가에서는 여러단의 침전조를 거치지만,대량으로 처리하는데는 적절치 못했고,침전조로부터 유출되는 물에 희석시켜 일반 하천에 방류시킴으로서,이들에 의한 하천오염이 큰 문제로 지적되고 있다.본 발명은 이와같은 축산분뇨중 특히 돈분뇨의 수처리에 대한 방법으로서,돈분뇨 원액을 원심력,또는 스쿠루압착식인 원심고액분리기를 통해 1차고형물과 1차뇨액으로 분리해내는 단계;1차뇨액에 중량비 0.2∼0.5%의 고분자응집제와 중량비 0.5∼1.0%의 황산알루미늄를 혼합해 편심원판상의 채반이 회전되는 진동스크린에 보내 분리된 2차고형물은 퇴비화시키는 단계;분리된 2차뇨액은 잔류시간 1000ℓ/1hr의 침전조에 잔류시켜 침전고형물은 상기 1차처리단계의 고형물처리단계로 재처리시키고,상등분리된 3차뇨액은 미생물폭기처리조와 활성탄조에 경유하는 단계;침출된 최종수는 톱밥 또는 왕겨등의 수분조절재에 분무살포해 송풍건조,또는 액비살포,살균후 사육장세척수이용하거나,고형물은 발효사료화로 처리본 발명이 이루고자 하는 기술적 과제이다.
