摘要
采用发光细菌法对苇浆OHMP漂白废水进行了毒性研究,实验结果表明,O段废水的EC50为233.4%,属于无毒级别;H段废水的EC50为224.0%,属于无毒级别。总毒性排放因子(TEF)为53.89 TU.m3/t浆,其中O段废水的TEF为26.54 TU.m3/t浆,占总量的49.2%,H段的TEF为27.35TU.m3/t浆,占总量的50.8%。总毒性排放负荷相当于HgCl25.388g/t浆,毒性排放负荷较小。
The toxicity of OHMP bleaching effluent was studied with photobacteria in this paper. EC50 of the O stage was 233.4%, belonging to no toxicity level. EC50 of the H stage was 224.0%, also at no toxicity level. The toxicity discharge load of the O stage was 26.54 （TU·m^3/t pulp）, about 49.2% of the total toxicity discharge load. The toxicity discharge load of the H stage was 27.35（TU·m^3/t pulp）, about 50.8% of the total toxicity discharge load. The results showed that the toxicity of the bleaching effluent was low, it was about 53.89 （TU·m^3/t pulp）, and equivalent to 5.388（g HgCl2/t pulp）.
