rotating biological contactor water treatment device that can improve water pollution in rivers

摘要

The present invention relates to a rotary disk contact method (RBC) in the treatment process of sewage or wastewater, and more particularly, in the RBC process, continuously using a heating tank in winter to prevent the death of microorganisms due to a decrease in temperature in winter. It relates to a rotary disk contact type water treatment device capable of improving the water pollution of rivers, which can prevent a decrease in efficiency due to the death of microorganisms even in winter by maintaining the temperature and water temperature inside the rotary disk contact tank by heating the water. To this end, the rotary disk contact type water treatment device capable of improving the water pollution of the river according to an embodiment of the present invention is a separation tank that separates foreign substances by specific gravity difference, and a primary for precipitating and removing sediments such as sludge from wastewater A settling tank, a warming tank that warms the wastewater, an equalization tank that mixes the wastewater directly transferred from the primary settling tank and the wastewater warmed in the warming tank to maintain it at an appropriate temperature, and a number of rotating disks are stacked on the surface of the rotary disk Microorganisms separated from the rotating disk contact tank and sludge and the rotating disk that can treat wastewater under aerobic conditions by receiving oxygen from the air and receiving organic matter when the microbial film is proliferated and the rotating disk is submerged in water. It includes a secondary sedimentation tank that settles them and discharges only treated water.
