Abstract
Use fly ash, cement, lime, gypsum as main raw material, CaCl2, Na2SO4 and NaCl as complex additive, use steam curing method, in the process of preparation of ceramsite, add vermiculite with Co2+, then obtain ceramsite which can release Co2+ slowly. Experimental results show that the releasing content of Co2+ increases with the ruse of the temperature, from the fourth day, all can reach a certain balance concentration. Through contrast test with the control group, add Co2+ group and slow-release Co2+ ceramsite group in the microbial reactor can obtain: removal rate of add modification ceramsite is the peak, can reach up to 90.32%, 30.06% higher than control group, 14.48% higher than add Co2+ group.Slow-release ceramsite can significantly increase the activity of activated sludge, comparing with other ceramsite and add trace metal element directly, which has more superior process performance.
