摘要
采用发光细菌法对苇浆CEH三段漂白废水进行了毒性研究,其中C段废水的毒性最大,其EC50为17.39%,属于强毒级别;E段、H段废水的EC50分别为163.6%、252.4%,均属于无毒级别.苇浆CEH漂白工艺总毒性排放因子(TEF)为472.021TU·m3·(吨浆)-1,其中C段废水的毒性最大,其TEF为393.88TU·m3·(吨浆)-1,约占总量的83.45%,其次是E段废水,约占10.03%,H段最小,约占6.52%.
The toxicity of CEH bleaching effluents was studied with photobacteria. The toxicity of C stage was the strongest, its EC50 was 17.39%, belonging to the strongest toxicity level. The EC50 of E, H stages were 163.6% and 252.4% respectively. Both belonging to the no toxicity level. The total toxicity emission factor (TEF) of CEH was 472.021 TU·m3·t-1. The TEF of C stage was 393.88 TU·m3·t-1, about 83.45% of the total toxicity emission factor. The TEF of E and H stages was 10.03% and 6.52% respectively.
