A research on application of water treatment technology for reclaimed water irrigation

• Explore the reclaimed water treatment technologies and modes for farmland irrigation.
• Adopt hybrid technology on reclaimed wastewater for irrigation, improving water utilization ratio and labor productivity.
• Study on technological mode on recycling of reclaimed water in farm irrigation for nationwide development and promotion.

Water, taken as the source of life, is one of the most important constituent parts of the global ecological system. The water resources problem is becoming more and more severe as a result of the acceleration of the process of urbanization in China and an increased population since reform and opening up. Therefore, reclaimed water irrigation is one of the effective measures to deal with the scarcity of water resources. In line with the necessity and urgency of reclaimed water reuse at present, brief analyses are made on the determination of both the reclaimed water treatment and the relevant irrigation technology, and then explanations and studies are made from such perspectives as the construction purpose, the water quality standards and the technological process. Finally the relevant new technologies and technical requirements for the reclaimed water treatment are put forward for the reclaimed water irrigation from such aspects as the techniques and technologies related to sewage treatment, the technical requirements and standards for reclaimed water irrigation, and the management and monitoring of reclaimed water irrigation.
