초록
본 연구는 PI 개념에 근거한 수처리용 인라인 혼화 및 응집 시스템의 성능특성에 대한 실험적 연구를 목적으로 한다. 3단 인라인 혼화 및 응집 시스템은 처리 원수 저장조, 응집제 주입 정량펌프, 혼화및 응집관, 침전조 및 제어 판넬로 구성된다. 동일한 응집제와 응집보조제의 주입량 조건에서 응집제의증가에 따른 탁도 제거율에 비해 응집보조제의 증가에 따른 탁도 제거율이 약 3배 정도 높게 나타났다. 동일한 혼화 및 응집 시간 조건에서 인라인 방식이 기계식에 비해서 평균적으로 약 4.6배 정도 탁도 제거율이 높게 나타났다.
Abstract
The objective of this study was to investigate the performance characteristics of an inline mixingand coagulation system for water treatment based on the process intensification concept. Three-stage inlinemixing and coagulation system was composed of the reservoirs of source wastewater, the fixed quantity injectionpumps of coagulants, the mixing and coagulation tubes, a sedimentation tank and a control panel. Inthe equal dosage of coagulant and coagulant aids, the turbidity removal with increasing the dosage of coagulantaids was about 3 times higher than that with increasing the dosage of coagulant. In the condition of theequal mixing and coagulation time, the turbidity removal of inline mixing and coagulation system was about4.6 times higher than that of mechanical type.
