Abstract:
Disclosed is an apparatus for early rainwater purification, comprising: a precipitation tank, an inlet filtering layer, a buffering tank, a downflow filtering tank, a porous pipe, and a vertical pipe, all arranged within a rectangular housing made of concrete. In the apparatus for early rainwater purification of the present invention, early rainwater filling the buffering tank passes through a screen formed at a side surface of a main filtering layer to form a downflow to be filtered. The level of the early rainwater is then lower than the surface of the main filtering layer. The apparatus of the present invention is advantageous in that offensive odors and the breeding of harmful insects caused by the water contained in the housing are prevented by the main filtering layer, the surface of which is exposed. Further, the apparatus for early rainwater purification of the present invention enables superior rainwater purification, convenient maintenance, and simple construction, and is inexpensive.
