摘要： PROBLEM TO BE SOLVED: To extremely inexpensively produce iron powder which can be produced at high productivity without using large-scale production equipment, and is excellent in the decomposition efficiency of an organic chlorine based compound, and does not newly contaminate the environment when used as a soil cleaning agent.
SOLUTION: Dust in an exhaust gas produced in the process of refining from a converter for steel making is collected to recover steel making dust 22 from the exhaust gas. The recovered steel making dust is sorted by a magnetic separation stage 23, and is separated into magnetic products 24 and non-magnetic products 25. Then, the magnetic products 24 are subjected to cleaning 26 with water to remove depositions, so that iron powder 27 is produced from the steel making dust. In this case, it is preferable that the steel making dust is coarse-grained dust 19 recovered from slurry-like dust collection water recovered with a wet dust collector by using a coarse grain separator set on the upstream side of a thickener, the content of metal iron in the iron powder is ≥70 mass%, and the obtained iron powder 27 is kept in water.

摘要： PROBLEM TO BE SOLVED: To provide an inexpensive plant cultivation device provided with a water absorbing body and enabling stable water supply for a long time. SOLUTION: The plant cultivation device 1 has the following: a container 3 retaining water 17 in its lower part and storing planting soil 16 in its upper part; a water absorbing body 5 for sucking up the water reserved in the lower part of the container to supply the water to the planting soil due to the capillary phenomenon; and a communication hole 8 securing ventilation between a portion for reserving the water in the container and the open air, and also supplying the water in the container to the portion for reserving the water. The water absorbing body 5 comprises an outer cylinder 7 having ventilation holes 7a at its sidewall, and a packed layer 6 comprising coke powder charged in the outer cylinder.
