设施内灌溉首部河水处理技术及装置设计应用探索

Application exploration of river treatment technology and equipment design in irrigation head work of greenhouse

我国水质性缺水现象十分严峻,河流湖泊水受污染现象普遍,并且河道水中悬浮物颗粒粒径无法满足微灌工程的要求,水质问题已严重影响到农业日常生产活动,因此研究适用于设施菜地灌溉系统的河水处理技术及其相应的处理装置迫在眉睫。介绍加压溶气气浮法在农业灌溉水源处理中的应用,探索相关技术应用的原理、结构、工艺,设计相应的装备,结合实际应用过程中发现的问题,探寻改进和完善的途径,并探讨气浮净水技术、设备在农业灌溉领域的研究方向。

China has long suffered from a scarcity of clean water, river and lake water pollution is widespread. Grain diameter of suspended solids in river water couldn＇t meet requirements of micro-irrigation, and water quality has a strong impact on agricultural production. Therefore, research on river water treatment technology and equipment for irrigation system of greenhouse is extremely urgent. Introduce the application of dissolved air floatation in agricultural irrigation water treatment. Related theory, structure, technology had been explored, necessary instruments had been designed. Combining with the problems occurred in practical application, looking for the way to improve and refine, discussing research direction of air floatation technology and equipment in agricultural irrigation field.
