STUDY ON NONMETAL MINERALS ABSORBING NH₃ - N FROM COKING WASTE WATER

This experiment is to take somekinds of modified nomnetal minerals, such as Attapulgite, zeolite and Bentonite as sorbent, and absorb NH₃-N in coking waste water, and the result of this experiment shows that the rate of removing NH₃-N is 75 %, and the result of this experiment have some application value. Bases on this, the author makes preliminary design and judgement for industrial application.
