Use of Rice Husk Ash to Treat Simulated Agricultural Cultivation Wastewater

Abstract:

This laboratory-scale study explored the use of rice husk ash (RHA) as absorbent to stabilize and solidify the simulated agricultural cultivation wastewater. Various factors including the shaking time, solution pH, the dosage of absorbents and the temperature of the heating were taken into account and promising results obtained. The results showed that the RHA at 300°C of heating temperature has a better efficiency on the removal of COD and NH₃-N. The initial solution PH of 5~6 was most favorable for COD and NH3-N removal. The removal rate of COD and NH3-N is nearly 25% and 18% respectively under the conditions of the pH=5.5, shaking time of 30 minutes and quality of RHA of 6.0g. The results suggested that absorption treatment of simulated agricultural cultivation wastewater with RHA is an effective method to remove the COD and NH₃-N.
