| Abstract: | The characteristic and treatment status of coal gasification wastewater has been discussed and analyzed and ammonia nitrogen removal efficiency of the falling film process in treatment of coal gasification wastewater is summarized,as well as the effects of flooding velocity,film thickness,pH value and temperature on ammonia nitrogen removal.The results show that ammonia nitrogen removal rate can be increased to above 95%,the reagent cost of pH adjustment be reduced and scaling phenomenon be effectively alleviated,which is prospective and should be spread in the similar industrial waste water treatment projects. |
