Patent ID: 10894729

Abstract:
This disclosure discloses an apparatus of treating a river, comprising a river bed sludge suction device, a container-type sand-stone refuse separation device, a container-type dehydration device, a container-type pulverization device, a storage container, a container-type drying device, a container-type carbonization device, a container-type flocculation device, a container-type precipitation device, a container-type activated coke filtration and adsorption device, a container-type power generation device, a container-type operation and control chamber, and a cleaning ship for floating debris and river bank refuse. This disclosure discloses a method of treating a river using the apparatus described above where a biochar is produced from the separated, dehydrated and dried sludge. The biochar is then delivered back to the river bed to adsorb nitrogen and phosphorus, cleaning the river water, followed by purification treatments on sewage discharged from the dehydration apparatus and discharging the treated sewage water back to the river.
