Abstract:
The purpose of the present invention is to provide a water current circulation apparatus which induces the descent of a water current by self-rotating in accordance with a wind direction frequently varying in stagnant water bodies such as the stagnant water zones of a reservoir, a lake and a bog, and a river and closed coastal zones, and maximizes a water current circulation effect when maximally receiving surface drift currents by applying the properties of a drift current, thereby reducing eutrophication in the water bodies, preventing the excessive growth of algae, and improving water quality. According to the present invention to accomplish the purpose, a water current circulation apparatus in stagnant water body sections including the stagnant water zones of a reservoir, a lake and a bog, and a river and closed coastal zones comprises: an anchor member fixed to the bed of a water body; a supporting shaft vertical to the water body, installed on the anchor member, and capable of freely rotating; a floating member installed at the upper side of the supporting shaft; a wing blade installed on the upper side of the floating member, and facing wind; and at least one drift current descent inducing member installed at the lower side of the floating member, and inducing a drift current at the surface portion of the water body to descend toward the deep portion of the water body.

PURPOSE: A water pollution apparatus for using a stray type plant hair board replacing the required site in the natural purification with the unused land is provided to purify the water pollution apparatus for reduction using the stray type plant hair board before contaminant by the outflow of the rain. CONSTITUTION: A water quality pollution reduction apparatus includes a plant seedbed mat(200), a plant hair board and a fixing support. The plant seedbed mat is settled inside the equation watered seedbed. A punched part(120) is formed in the side of the equation watered seedbed. The steady rest is inserted into the punch station of the equation watered seedbed. The steady rest from side to side controls the equation watered seedbed. In order that the equation watered seedbed freely moves to the top and bottom, the steady rest supports the equation watered seedbed.
