The CODCr composition of heavy oil effluent has been studied, and the reason of the hardness of its treatment has been discussed.A novel method of CODCr treatment is given.The results show that the CODCr of heavy oil effluent is composed of organic chemical agentswhich are left from oil and water.For fresh effluent the CODCr percentages of oil and chemical additives are 60.7 %and 39.3%respectively.The equation,CODCr=4. 391 2X +0.617 1,can express the oil content contribution to CODCr.The main reason of the hardness of CODCr treatment exists in the disposal difficulty of chemical additives in the effluent.The selective flocculation effect of the biodegradation by the complex flocculant is proved to be feasible
