TREATED-WASTEWATER REUSE SYSTEM FOR AGRICULTURE AND USING METHOD THEREOF

摘要

A system for reusing treated wastewater as agricultural water, which can inexpensively treat wastewater to a proper water quality level capable of being used as agricultural water, and a method for using the treated wastewater as agricultural water after treating wastewater using such a system are provided. In the system for reusing treated wastewater as agricultural water by allowing a filtering equipment to filter wastewater supplied from a wastewater treatment plant in which ordinary wastewater is collected, disinfecting microorganisms contained in the filtered water by ultraviolet disinfection, storing the disinfected water in a detention pond, and supplying the stored water as agricultural water as occasion demands, the system is characterized in that the filtering process is performed by filtering wastewater using a slow sand filtration equipment, the disinfection process is conducted by a UV(ultraviolet) disinfecting facility in which UV lamps are mounted, and the water storing process is performed by a constructed wetland and a detention tank.
