Study On the pretreatment of aquatic product wastewater containing sodium hypochlorite
FeSO4 regarded as coagulating agent is used for pretreating aquatic product processing wastewater containing sodium hypochlorite with high concentration． The results show that BODy／COD can be increased from 0．13 to 0-40 under the condition that pH is ranged from 8．5 to 9．0 and the dosage of FeSO4 is 3 g／L． Simultan eously sodium hypochlorite has less efect on the biodegradability which Can be enhanced effectively under this condition．After the pretreatment of coagulation．the removal eficiency of COD iS from 26．40％ to 28．64％.And the fu11．scale experiment shows that using FeSO4 as coagulant Can get better treatment efect．
