Beschreibung
Zusammenfassung:	The invention discloses a method for treatment on a 137Cs radioactive waste liquid by microbe adsorption. The method is characterized in that a pH value of the 137Cs radioactive waste liquid is adjusted to 2.5-9; rhodosporidium toruloides are added into the 137Cs radioactive waste liquid at a temperature of 5-40 DEG C; after 137Cs are fully adsorbed by rhodosporidium toruloides, the rhodosporidium toruloides are separated; the separated rhodosporidium toruloides with 137Cs are subjected to radiation-resistant storage; and the liquid satisfying radioactivity standards is directly discharged by a non-radioactive waste water discharge method. The method for treating the 137Cs radioactive waste liquid has a highest 137Cs adsorption rate of 95% and a wide application range. The method provides an effective means for 137Cs radioactive waste liquid treatment.
