| 摘 要： | 为解决传统压力式砂滤罐长时间工作后截留大量固体颗粒物而导致的难以反冲洗的问题,该研究在原有设备基础上进行技术改进;研制出了1种可以边工作边反冲洗的气提式砂滤器;气提式砂滤器集过滤、分离、气浮、自动清洗等功能于一体,可以替代传统用于养殖车间的砂滤罐、无阀滤池、微滤机、机械式气浮等物理过滤装置;试验用1~2 mm石英砂作为过滤介质,过滤水以向上流方向从气提式砂滤器底部慢慢上升,污物被石英砂截留,同时,从底部流入定流量气体,使得污物和砂粒同时被提起,最终在顶端的洗砂装置中石英砂被清洗干净并由于重力作用而落回系统,污物和废水从排污口流出;试验表明,气提式砂滤器设备简单、操作简便,不需停机反冲洗,系统运行连续平稳,能耗小并且易于日常维护和检修;数据表明,这种气提式砂滤器对海水循环水养殖系统中的颗粒悬浮物(suspended solids,SS)和化学需氧量(chemical oxygen demand,COD)平均去除率分别为(41.31%±7.72%)、34.04%,同时也降低了氨氮、亚硝酸盐含量,过滤后养殖水颗粒悬浮物质量浓度≤67.33 mg/L。气提式砂滤器在海水循环水养殖系统中进行物理过滤,是1种行之有效的方法,满足了养殖车间的水处理要求。
