A Study on the Treatment of Wastewater from Reproduced Papermaking Using Microbial Flocculants by Mycelia Pellet

摘要：

A new type of effective coagulant Microbial Flocculants was prepared from A-spergillus oryzae and used as coagulant in the treatment of papermaking wastewater. The experimental results showed that it had a good coagulation effect in the treatment of papermaking wastewater in a wide range of pH value. The removal rate of SS and CODCr was 97% , 81 % respectively in the condition where temperature was normal , pH value was 7.0 and dosage of the coagulant was 25mg/L.The temperature had little impact on the removal rate of SS. But had impact on the removal rate of CODCr.In comparison with the conventional coagulants.such as Al2 (SO4) 3 and FeCl3,the coagulation performance of Microbial Flocculants was the best. The remarkable characteristics of this method were higher settlement rate and without adding salt which accumulated can do harm to Paper technology
