MICROORGANISMS - INHIBITORS OF ACTIVATED SLUDGE FILAMENT SWELLING

A collection of microorganisms-inhibitors of filamentous swelling of activated sludge was created. The most promising for inhibiting the growth of filamentous prokaryotes are strains of Pseudomonas sp. PT2 and Bacillus sp. FL X-5. It is shown that the introduction of microorganisms-inhibitors of filamentous prokaryotes has a positive effect on activated sludge at the initial stage of filamentous swelling: the oxidizing power of sludge increases by 10-40%, the efficiency of wastewater treatment increases by 1.8-2.2 times, the sedimentation properties of sludge improve, the number of representatives of the main indicator groups increases by 2 times, the filament index decreases from 3-4 to 1.
