Specific embodiment
With reference to the accompanying drawings, the utility model is further described below.
The utility model discloses a kind of waterborne radioactivity radium elements to remove system, is different from the prior art and is：Institute
System is stated to include automatic feeding unit 1, radium-bearing underground tank 2, be stirred pond 3, ceramic membrane filter device 4, the automatic throwing
Unit 1 is added to be connect with being stirred the feeding port in pond 3, radium-bearing underground tank 2 is connected by pipeline with being stirred the water inlet in pond 3
It connects, overflow port 4 is equipped at the above-mentioned pond body wall for being stirred pond 3, be stirred pond 3 and filled by overflow port 4 and ceramic membrane filter
5 connections are put, the water outlet of ceramic membrane filter device 5 is connect by the first pipeline 9 with the water inlet of filtering production water pump 6, filter production water
The water outlet of pump 6 is connect by the second pipeline 10 with producing the water inlet in pond 7, one end of counter-flushing pipeline 8 and the second pipeline 10
Connection, the other end connect with the water outlet in backwash production pond 11, backwashing pump 12 is provided on counter-flushing pipeline 8, it is ceramic
