A removal method of organic matter etc. in rivers used pressure waters and apparatus therefor

摘要

The present invention relates to a method for removing contaminants, nutrients, and algae of a lake using pressurized water, and an apparatus thereof. The purpose of the present invention is to transfer contaminants by transporting water, which has increased pollution in lakes, reservoirs, dams, and streams, to a treatment tank. And to provide a method and apparatus for removing pollutants, nutrients, algae of appeal using pressurized water that can be removed nutrients and algae reliably, and sludge generated during the purification process can be recycled as compost, The configuration includes the steps of sucking raw water into the active water tank unit; An activation step of activating the treated water by supplying ultra-fine foam guns to the raw water in the active water tank unit; Introducing the treated water activated in the activated water tank into the treated water tank; A pressurized floatation step of supplying ultra-fine strength guns to the treated water introduced into the treated water tank unit to float the floating sludge remaining in the treated water; Precipitating sludge contained in the treated water flowing in the treated water tank; Removing and accumulating the flotation sludge that has been injured through the pressing flotation step; Recycling the precipitated sludge accumulated through the precipitation step into an active water tank; Dewatering and drying the integrated flotation sludge; Recycling the leachate generated by dehydration of the flotation sludge to the active water tank unit; Discharge the treated water passing through the treated water tank unit.
