PURPOSE: A variable retaining-wall water tank for processing initial rainwater is provided to be assembled through a plurality of unit blocks and to maximize purification by the increase of dissolved oxygen of rainwater. CONSTITUTION: A variable retaining-wall water tank(100) for processing initial rainwater comprises first and second blocks(110,120), a partition block(130), a side block(140), a cover member(150), and an oxygen supply device. The first and second blocks comprise first and second horizontal portions and first and second vertical portions. The partition block is installed between the first and second blocks to partition an inner space. The side block is installed between the first and second blocks to form an outer wall. The cover member is placed on the tops of the first and second blocks and the partition block to partition an inner space. The oxygen supply device is installed on the cover member to increase the dissolved oxygen of the water. |
