FIELD: chemical technology. SUBSTANCE: invention relates to method for treatment of acrylamide aqueous solutions from slime of biocatalyst followed by polymerization of slime. Biocatalyst slime with content of acrylamide from 0.2 to 5% is polymerized after filtration by heating by any known method being without addition of polymerization initiating agent in the amount 0.05-0.5 wt.-% at temperature 30-140 C for 10-400 min. Potassium or ammonium persulfate is used as an initiating agent. Method provides utilization of biocatalyst slime to obtain water-absorbing filled polymer useful for utilization in rural and park industry and for soils reinforcing. Invention allows solving problems associated with the enhancement of filters output and the complete ceasing slime drop with sewage. EFFECT: improved utilizing method. 2 cl, 1 tbl, 12 ex
