摘要:
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 processing system and method for reducing pollution loads is provided to enable a user to control and management the system at a remote and to reduce personnel cost. CONSTITUTION: A processing system for reducing pollution loads is as follows. The overflow water quality and flow rate are measured in a pipe conduit. The outflow pollution loading is calculated based on the data of water quality and amount measured in real time. The residual detention storage of an undercurrent facility(20), in which rain fall flows, is calculated. The inflow flux and discharge flow rate from and to the undercurrent facility are controlled based on outflow water quality, outflow pollution loading and residual undercurrent capacity. The nutriments of the inflow water of the undercurrent facility are eliminated. The processed water without nutriments or the remainder of outflow rain fall is bypassed. The control of an inflow rate and outflow rate is controlled by a pump and water gate.
