Development of Solid/liquid Separation Technology for Stall Wastewater
畜舍尿汚水의 物理的 固液分離技術 開發
Abstract
Solid/Liquid(S/L) separation is crucial for biological treatment of animal wastewater. Liquid portion from S/L separation has less BOD-load and proper post-strip treatment can be obtained. Screen or declined sieve was normally used to separate the solid parts. For better separating efficiency a vibration and a cylindrical separator were constructed and tested. The results are summarized as follows; Solids removal efficiency and moisture content of separated solid were 15~26% and 85~88%, respectively for the vibration separator. for the cylindrical separator, solid removal efficiency and moisture content of solid were 16~39% and 86~89%, respectively. The greatest amount of drymatter was obtained when operating vibration separator with 10
축사뇨오수의 전처리단계로 고액 분리기를 제작하여 분리효율에 관한 시험을 수행한 결과는 다음과 같다. 진동체 고액분리기는 최저 15%에서 최고 26%까지 분리율을 나타내었으며, 분리고형물의 수분함량은 85~88% 사이였다. 회전원통형 고액분리기도 최저 16%에서 최고 39%까지 분리율을 나타내었으며, 고형물의 수분함량은 86~89% 사이였다. 최대의 분리고형물량은 진동체 고액분리기의 경우에 체의 경사도
