POSSIBILITY OF THE USE OF SINGLE-CELL ALGAE CHLORELLA VULGARIS IN THE GEL SWELLING OF ACTIVATED SLUDGE IN BIOLOGICAL WASTEWATER TREATMENT PLANTS PULP AND PAPER INDUSTRY
Waste water of the pulp and paper industry is characterized by a high content of hard-to-oxidize organic compounds. Often, wastewater treatment in the pulp and paper industry is carried out by biochemical method in aeration tanks.Gel swelling of activated sludge in the process of wastewater treatment of the pulp and paper industry is an urgent technological problem.In order to solve this problem, the use of unicellular algae Chlorella vulgaris was considered.The positive effect of Chlorella on the biocenosis of activated sludge in the fight against gel swelling of activated sludge has been proved.
