[Problem] The purpose of the present invention is to provide a rainwater treatment system and a rainwater treatment method capable of producing pure water by removing impurities contained in rainwater at a low cost without requiring external motive power. [Solution] A rainwater treatment system 1 comprises a rainwater storage tank 10, a first filtration tank 20, a second filtration tank 30, and a filtered water storage tank 40. Among impurities contained in rainwater that has flown into the first filtration tank 20, impurities having a greater specific gravity are deposited at the bottom, and impurities having an equal specific gravity are captured by a first filter 21. Further, impurities having a smaller specific gravity are drained outside the system as overflow water. Accordingly, pure water having a high purity can be produced by efficiently removing impurities without requiring external motive power.
[Problem] To provide a heat transfer member and a radiation panel that exhibit efficient radiation to thereby accelerate heat exchange with the outside and that enhances comfort for users. [Solution] A radiation panel 1 according to the present invention is provided with a panel body 2 which has a heat medium flow pipe 5 between a pair of left and right columns 3, 3. The panel body 2 has a plurality of long heat transfer members 4 which extend along the vertical direction and are arrayed in parallel between the columns 3, 3. The heat transfer members 4 each have a long body part 40, and openings 42 are formed on both sides of the body part 40 so as to be continuous along the longitudinal direction. Since a hollow part 41 and the external space are connected through the openings 42, heat will not be retained inside the hollow part 41, and heat exchange with the outside can be actively accelerated. Thus, heat exchanging performance can be improved.
