Abstract: The present invention relates to a method for manufacturing a water purifying agent using natural materials and more specifically, to a method for manufacturing a water purifying agent using natural materials, which is eco-friendly and economical by being manufactured using natural mineral matters, vegetable matters and sludge in a water purification plant, can remove green tide, can sterilize harmful germs, and can remove other pollutants by adsorbing and floating the pollutants. The present invention comprises the steps of: preparing dried sludge in a water purification plant, which is in the state of cake; pulverizing the dried sludge; thermally treating the sludge in the powdered state at a temperature of 600-700°C; pulverizing mineral materials such as zeolite, quartz porphyry, silicate, loess and sericite; dissolving mineral components by soaking the mineral materials and the sludge, which are in the powdered state, in water, and heating and stirring the mineral materials and the sludge in a high-pressurized chamber at a temperature of 150-250°C for two to three hours; acquiring water in the state of colloid having the mineral components dissolved therein by precipitating minerals and sludge sediment; crushing plant materials such as chestnut trees, oak trees, green tea, ash trees and pine needles into minute particles; extracting natural sterilizing components by heating and vibrating, with supersonic waves, the crushed plant materials in water at a temperature of 50-70°C for one to two hours; acquiring natural sterilizing liquid by removing plant sediment with a filtering net; and manufacturing the water purifying agent by mixing the water in the state of colloid having the mineral components dissolved therein and the natural sterilizing liquid in a volume ratio of 0.8-1.2:0.8-1.2.
