The incidents of sudden pollution of ammonia nitrogen are happening quite frequently recently. To study the effective removal of ammonia nitrogen, using zeolite powder as an absorbent, the simulation of ammonia- nitrogen wastewater is studied systematically through investigated experiments. The effects of absorption time, ambient temperature, the original ammonia nitrogen concentration, the amount of zeolite and other factors arediscussed. Results of experiments show that the absorptiondoi:10.3303/CET1546014 doaj:dd415e010c7442ad9b73bb35bb838c9f fatcat:3v5at2jgzjdfxmvbjw5c4uzy3y
