Irrigation water quality influences many aspects of agroecosystems, but less is known about how complex microbial and biological communities respond to changing water quality due to causes such as reuse irrigation. The objectives of this study are to monitor and assess the environmental impacts of reclaimed wastewater irrigation on water quality and soil that might cause potential health hazards and to assess its agro-environmental effects. Two sites, which are irrigated by filtered wastewater after UV (Ultraviolet) treatment and from an agricultural reservoir that satisfied the agricultural water quality standards of Korea, were selected as treatment and control, respectively. The environmental impacts of irrigation water quality on paddy soil, microorganisms, and arthropods were investigated. Monitoring results for water, soil, health risks, and eco-environments of the reclaimed wastewater irrigation site demonstrated no adverse effects in the paddy field. This research showed that reclaimed wastewater irrigation did not present significant environmental risks for the rice paddy agroecosystem, although long-term monitoring is needed to fully characterize its effects. 相似文献

This article describes the pilot study on the water reuse for agricultural irrigation in Korea. The project is a part of the
application of wastewater reuse system for Agriculture project, a 21st Century Frontier R&D Program sponsored by the Ministry
of Education, Science, and Technology and associated with the Sustainable Water Resources Research Program. The goal of the
project was to develop infra-technologies necessary to reclaim wastewater for irrigation in agriculture. The project involved
two phases: laboratory and field research. Reclamation techniques for irrigation and feasible reuse were developed as a first
step in proposing appropriate water quality standards. Reclaimed wastewater of various qualities was used to irrigate cereal
crops and vegetables, and possible adverse effects on crops, humans, and the environment were investigated. The optimal reclamation
methods required to satisfy water quality standards were explored and the operational characteristics investigated. Moreover,
an inventory of farmlands that could reuse reclaimed wastewater was established. Feasible delivery systems for irrigation
were developed, and pilot project sites were identified. Finally, operational field data from pilot units were collected and
analyzed. This research and development may help solve water shortage problems in Korea, which left unaddressed will have
an adverse effect on future generations. 相似文献
