透析用水处理设备的配置分析

The Configuration analysis of water treatment equipment for hemodialysis

透析用水处理设备在透析治疗过程中起着关键性的作用,它由预处理、反渗透机、供水管路组成。由于某些厂家的配置和结构不是很科学,故对水处理设备的配置进行分析,对于透析室工程师,甚至是采购的决策者有着重要意义。怎样才能做到科学合理地配置,主要要考虑:选用采用循环供水方式的透析用水处理设备;主机的产水量达到在特定水源温度下满足无菌透析用水量的基本要求;供水管路管径的选取既能满足循环管路最小流量的要求,又能使设备在正常工作压力下工作;预处理系统最好完备,但树脂罐和活性炭罐的容积和充填量以够用为原则;反渗透系统宜采用双级反渗透系统,纯水、浓水的回流位置和级间匹配问题可根据具体需要确定。

The water treatment equipment for hemodialysis plays an important role in the process of dialysis treatment. It is made up of pretreatment,R.O treatment and water supply piping. But nowadays,the configurations and structures of some manufacturers are not very scientific. Therefore,we analyze the configuration of water treatment equipment,which is quite important for hemodialysis engineers and even buyers who make the decision. But how to make a scientific and reasonable configuration？ It must take 5 aspects into account. Firstly,we should adopt the water treatment equipment for preparation of dialysis fluids with a circulation water supply mode. Secondly,the host machine＇s amount of water must meet the amount of water to asepsis dialysis under the given water source temperature. Thirdly,the choose of the water supply piping can not only supply the least flux,but also make the equipment work under the normal work pressure. Fourthly,we should make the principle that the pretreatment system should be perfect,but the volume and filling amount of the colophony jar and active carbon jar just be enough to use. Finally,it is befitting for hemodialysis to adopt two-level R.O treatment system. At the same time,the circumfluence position and two levels＇ matching problem of pure water and thick water can be decided according to practical needs.
