中文摘要	引用高含沙地表水作为滴灌水源是解决干旱地区滴灌工程水源的主要途径之一,滴灌用高含沙水净化处理成为亟待解决的重要问题。以宁夏中南部地区设施农业滴灌用黄河水净化技术为对象,开展试验研究,主要结论有:扬黄水经2次沉沙池除沙后泥沙含量降至0.04~0.08 kg/m~3,悬浮物含量0.98~1.40 mg/L,COD平均含量 1.26~2.28 mg/L,已可满足滴灌要求;筛网过滤器在泥沙量0.05~0.08 kg/m~3时,除沙率约1%,过滤效果差;叠片式过滤器除沙率约5%,且优点较多可作为主过滤设备;过滤设备悬浮物去除率13.1%~20.6%,COD去除率 5.8%~26.5%,综合去除率21%~50%;宁夏半干旱风沙区和黄土高原区区域,以扬黄水为水源的设施农业,净化系统工程投资5.07~7.8万元/hm~2,其中工程净化投资4.8~7.35万元/hm~2,设备投资0.27~0.45万元/hm~2。
英文摘要	It is an important approach to solve water source for drip irrigation project in arid areas by using a high-silt content surface water.So,the technology of Purifying water for drip irrigation with high-silt content water is the first key question.In this paper,we did some experiment in central and southern regions of Ningxia province for the technology of purifying water for drip irrigation which was used by establishment agriculture with Yellow River water.Results indicate that:The Yellow River water passed two settling basins,the value of sediment charge ,suspension content and COD average content were drops to 0.04~0.08 kg/m~3,0.98~1.40 mg/L and 1.26~2.28 mg/L separately,which has been possible to satisfy for the drip irrigation.In case,the silt measures 0.05~0.08 kg/m~3,the gauze filter eliminates sediment about 1%,the filtration effect is bad.The stack type filter eliminate sediment ratio about 5% and more advance,so may take the main filter plant.Filter plant can eliminated suspension 13.1%~20.6%,COD about 5.8%~26.5%,synthesis elimination rate 21%~50%.In sub-arid wind desert region and the Loess Highlands area region of Ningxia province,the Yellow River water is a main water source for facility agriculture.Accord to calculating the purification system project may invest 50 700~78 000 Yuan/hm~2,there into,the project purification invests 48 000~73 500 Yuan/hm~2,equipment invests 2 700~4 500 Yuan/hm~2.
