PROBLEM TO BE SOLVED: To provide a foam floating type separator used suitably for a simple and small drain regeneration device for cleaning easily the drain of comparatively small volume. SOLUTION: An injection pipe 2 for injecting anyone of air, oxygen or ozone gas is connected with the middle of a liquid transfer line 1 for a liquid mixed with suspended matters, and a gas-liquid mixing device 10 is connected with the downstream side of the injection pipe 2 of the liquid transfer line 1 to mix the gas into the liquid. A cyclone type foam separation device 20 is connected with the downstream side of the drain outlet of the gas-liquid mixing device 10, and an outflow opening 22 for foams floated together with suspended matters is formed on the central upper section of the cyclone type foam separation device 20, and a treated liquid outflow opening 23 is formed on the lower outer peripheral section of a cyclone main body 21 to remove the suspended matters together with the foams. |
