Abstract: A method for removal of nutrient pollutants from waste water with activated coal ash as treating agent has been described. The results show that the processing accords to Freundlish adsorbtion isotherm within the limits of experimental conditions. After being used to process polluted water, this treating agent with concentrated pollutants can be applied to plant culture, so that the nutrient contained in it will be absorbed by the plants. By using this kind of waste water treating agent, it not only removes the pollutants from the waste water, but also changes the pollutants into the nutriment that may be absorbed by plant.

Key words: waste water, nutrient pollutant, absorbtion, reutilization
