A rainwater recycling system in a building is provided to collect, store, and recycle the rainwater in a tank, and to minimize sewage contamination and water damage by removing scum and heavy metals through first and second purification parts of a purifying part. A rainwater recycling system in a building comprises a drain facility(10), a purifying unit(20), a first tank(30), a first recycling water supply pump(40), an auto filter(45), a second tank(50), and a second recycling water supply pump(60). The purifying unit has a first purifying part(21) for separating precipitate, scum, and oil fraction from the collected rainwater for removal, and a second purifying part(22) for filtering the fine precipitate of the rainwater and filtering contaminants. The first tank has compartments(32-1,32-2,32-3,32-4) divided by partitions(31,31'). Each compartment has a nozzle(34) through which the air is supplied. The second tank has compartments(52-1,52-2,52-3,52-4) divided by partitions(51,51'). Each compartment is connected to a sterilizer(55). |
