| Abstract: | High strength and lightweight globular composites were prepared from different ratios of non-metallic mineral materials by activated treatment at high temperature.The influence factors of ammonium nitrogen absorption were studied.The results showed that the removal efficiency increased when the initial concentration and the time of absorption increased,when the initial concentration of ammonia nitrogen is less than 30 mg/L and the adsorption time is less than 1h,and pH value of solution is less than 7.0 and... |
