The author presents the results of microbiological studies aimed at investigating the deep removal of phosphates from household wastewater. A method for deep cleaning of waste water using reinforced materials is provided. The living culture study in activated sludge and biofilm in the light microscope showed activating effect of the reinforced loading material on the life of microflora in activated sludge and biofilm. A steel wire in the the feed material has a significant impact on the number and variety of species of protozoa in the activated sludge, and also leads to rapid development of Chlorella sp. The study of the living culture of activated sludge and biofilm in the light microscope showed that the reinforced material activates the vital functions of the activated sludge microflora and biofilms, as well as the diversity of their species composition. The studies have confirmed that chlorella multiplies in an environment rich with iron, absorbs phosphorus from the environment and actively produces oxygen, providing bacterial biomass with it. This fact explains the increase in the removal of organic contaminants, as well as the influence of the reinforced material on the second step of nitrification.

Subject: the article focuses on investigation of kinetics of sludge liquor sedimentation and on determination of its characteristics; the relations between parameters of activated sludge such as mixed liquor suspended solids (MLSS), sludge-water phase boundary and sedimentation rate are highlighted. Research objectives: research on kinetics and parameters of activated sludge sedimentation at city wastewater treatment plants (WWTP). Materials and methods: field tests of sedimentation process of real sludge samples from different WWTP in laboratory cylinders are conducted, mathematical and graphical processing of the obtained results is carried out. Results: kinetics of sedimentation of sludge liquor with MLSS equal to 0.6…6.2 mg/l is described, main dependencies between sedimentation characteristics of activated sludge are obtained. The regularities of sedimentation of sludge with small and large MLSS are noted. Conclusions: kinetics of sludge sedimentation for various MLSS is determined, the rate of elimination of “sludge-water” phase boundary is determined.
