PROCESS FOR PURIFICATION OF LIQUID RADIOACTIVE WASTES FROM ORGANIC SUBSTANCES AND URANIUM

摘要

A process for purification of liquid radioactive wastes (LRW) from organic substances, which are included in the dust control solution and LRW, and uranium, by which for the deacresing of the part of the secondary wastes coagulant-flocculant is used in the further filtering and at the LRW treatment stage silica- and aluminium-containing coagulant-flocculant of the type "Syzol-2500" is used at pH of 6-7, temperature of 5-30 °C and mixing of the mixture after addition of coagulant-flocculant and holding of the obtained solution for 0.5-3 hours and filtering on membrane with the size of pores of 0.2-3 micrometers.
