본 연구는 하수처리수의 농업용수 재이용에 따른 벼의 미질특성을 파악하기 위하여 시험포장을 조성 하여 쌀의 아밀로스 및 단백질 함량, 완전미 도정수율을 분석하고 유의성을 고찰하였다. 시험포장의 수 질 및 토양환경을 조사하였으며, 근적외선 분광분석법을 통해 미질 특성을 분석하였다. 하수처리수로 재 배된 쌀의 미질 특성치는 일반미와 큰 차이가 나지 않는 것으로 나타났으며, 통계분석 결과 5% 유의수 준에서 각 처리구별 유의차가 있는 것으로 나타났다.

In response to the water shortage problem, continued attempts are being made to secure consistent and reliable water sources. Among various solutions to this problem, wastewater effluent is an easy way to secure the necessary supply, since its annual output is consistent. Furthermore, wastewater effluent has the advantage of being able to serve various purposes, such as cleaning, sprinkling, landscaping, river management, irrigation, and industrial applications. Therefore, this study presents the possible use of reclaimed industrial wastewater treated with Birm filters and a UF membrane, along with an analysis on membrane fouling. The preprocessing stage, part of the reclamation process, used Birm filters to minimize membrane fouling. Since this study did not consider heavy metal levels in the treated water, the analyses did not include the criterion for irrigation water quality. However, the wastewater reclaimed by using Birm filters and a UF membrane met every other requirement for reclaimed water quality standards. This indicated that the treated water could be used for cleaning, channel flow for maintenance, recreational purposes, and industrial applications. The analysis on the fouling of the Birm filter and UF membrane required the study of the composition and recovery rate of the membrane. According to SEM and EDX analyses of the UF membrane, carbon and oxygen ion composition amounted to approximately 57%, whereas inorganic matter was not detected. Furthermore, the difference in the recovery rates of the distressed membrane between acidic and alkaline cleaning was more than ~78%, which indicated that organic rather than inorganic matter contributed to membrane fouling.
