1.反渗透水处理工艺流程的设计根据沧州中铁装备制造材料有限公司附近地表水水质较复杂、含盐量偏高的水质特点及该钢厂生产用水的水质要求,此套水处理系统设置了以沉淀池+多介质过滤器+自清洗过滤器为主的机械过滤装置,加上超滤系统作为反渗透的预处理系统,以反渗透系统为主脱盐装置的水处理系统设计。首先将地表水引入沉淀池中,期间添加絮凝剂,通过絮凝沉淀机理作用去除水中泥沙、大的悬浮物等颗粒污染物,降低水中的悬浮物;之后进入多介质过滤器
1. Design of reverse osmosis water treatment process According to Cangzhou China Railway Equipment Manufacturing Co., Ltd. near the material quality of surface water is more complex, high salt content of water quality and water quality requirements of the steel production water, the set of water treatment system set To the sedimentation tank + multi-media filter + self-cleaning filter-based mechanical filtration device, coupled with the ultrafiltration system as a reverse osmosis pretreatment system, reverse osmosis system based desalination water treatment system design. First of all, the surface water is introduced into the sedimentation tank, flocculant is added during the process to remove the particulate pollutants, such as sediment and large suspended solids, in the water through the action of flocculation and sedimentation to reduce the suspended matter in the water; and then enter the multi-media filter
