Abstract :
Organic matter and turbidity in micro-polluted water could influence adsorption result of zeolite. Enhanced coagulation could remove organic matter and turbidity effectively, reduce the competition between organic matter and ammonia nitrogen, increase ammonia nitrogen strain away rate. By adding zeolite powder after adding coagulants, when coagulant dose achieve 3mg/L, the strain away rate of zeolite could increase 7%. The removal effect is obviously higher than only adding zeolite powder.
