METHOD FOR REMOVING GREEN TIDE USING RIVERBED DREDGING FINE MATERIALS OF RIVER

摘要

The present invention relates to a method for removing a green tide using riverbed dredging fine materials of a river, which can constantly maintain the water depth of a river, and can suppress the excessive propagation of a green tide due to an increase in the amount of sunshine. The method of the present invention comprises: a riverbed flow forming process (100) having a riverbed flow beam (10) in which a riverbed flow is to be performed in a river, and performing the riverbed flow of the river; a river dredging process (200) of maintaining a water depth of the river in a constant level by dredging a river deposit; an aggregate sorting process (300) of sorting sand and gravel discharged in the river dredging process (200); a floating sludge separating process (400) of separating a floating sludge from a digging slurry water discharged in the aggregate sorting process 300; and a fine material spraying process (500) of spraying fine material water, in which the floating sludge is separated through the floating sludge separating process (400), into the river to adsorb and precipitate a green tide. Therefore, the riverbed flow is performed by having a dredging flow beam in a river, thereby minimizing organic matters forming nutrients for a green tide. Also, the water depth of the river can be constantly maintained through the river dredging, and the aggregate is secured through the river. In addition, the green tide generated by spraying fine materials obtained through a digging sludge generated in the river dredging process is adsorbed, precipitated, and removed.;COPYRIGHT KIPO 2019
