Abstract

Coal cinder and zeolite have been widely studied in wastewater treatment. However there are some problems with the materials, such as low mechanical strength, poor water resistance, difficult recovery of coal cinder, and poor stability, easy powder, high price of zeolite. To resolve these problems, a coal cinder-zeolite ball was developed with modified PVA adhesive . Then the adsorption performance and thermal regeneration for ammonia nitrogen were studied. The results showed that the adsorption process of the sorbent had a good match with pseudo-second-order kinetic model and Langmuir equation; the adsorption capacity of ammonia nitrogen calculated from Langmuir equation was 0.18mg/g which was larger than that obtained from coal cinder alone. And the sorbent has a good regeneration performance. and the best parameters of regeneration in the process of experiments was 170 , 4h. Under this condition, the regeneration efficiency reached 74%.
