FIELD: process engineering.
SUBSTANCE: invention relates to ecology and environmental protection. For cleaning filtering system is erected and used on soil slope surfaces. Filtering system is composed of the slope soil top layer processed with aqueous solution of polyelectrolyte complex. The latter comprises the mix of hydrolysed polyarcylonitrile and polyethylene polyamine at the ratio of 1:3.5-1:4.5, wt %. Processed soil sorption capacity saturated, said soil is removed and disposed or recovered.
EFFECT: simplified cleaning, higher erosion resistance of run-off surfaces.
