摘　　要：为厘清医疗建筑中低放射性废水处理衰变池设计的问题,对连续式衰变池设计导流墙和导流管的导流方式进行探讨,以便合理设计连续式衰变池、设计选用,并确保其水处理的效果。通过比较和分析导流墙导流和隔舱导流管方式衰变池的优缺点,分析了废水在不同导流方式下放射性废水实际停留最长时间与最短时间的停留时间差,得出导流墙导流出现的实际行程距离差的结果,指出导流墙开口的长度不宜小于0.5 m,导流管导流在垂直方向导流的设计需避免短流。同时,提出了导流墙导流的改进措施。其结论是:导流墙方式的布局在实际工程上的应用相对更多,不容易发生堵塞,也较为合适,但需要控制实际停留的时间差。对检修人孔的设置、通气的设计、沉淀物的处理等需要注意的问题,给出了相应技术措施的建议。In order to solve the problem of the design of the decay pool for the treatment of low radioactive waste water in medical buildings,this paper discussed ways of conducting the wall and pipe in the design of continuous decay pool.The purpose is to design the continuous decay pool rationally and ensure the effect of water treatment.By comparing and analyzing the advantages and disadvantages of the decay tank of the diversion wall and the bulkhead,it is analysis the difference between the maximum and minimum retention time of radioactive waste water under different diversion modes.It obtains the result of the actual travel distance difference of the guide wall,and the length of the opening of the guide wall should not be less than 0.5 m,and the design of the guide pipe in the vertical direction should avoid short flow.At the same time,the improvement measures of diversion wall are put forward.The conclusion is that the layout of diversion wall has been applied more in practical engineering,is not easy to jam,and is more suitable,but the time difference of actual stay needs to be controlled.Some suggestions are also given for the setting of manholes,design of ventilation,treatment of sediment and other problems needing attention.
