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.

This article considers the main aspects of the process of self-purification in the marine environment. It describes mechanics of biogenic elements of the marine environment in the process of production and destruction of autochthonous and allochthonous organic matter. This article discusses organics and flows of energy, which migrate to the trophic chain of the marine environment in the process of self-purification. And it shows the individual elements of the process of self-purification in the marine environment and the factors influencing it. In the article it is noted that self-cleaning of water environment happens due to the cycling of matter in the pond. It is emphasized that tension, focus and self-purification completeness are regulated by biotic turnover and energy turnover, which is determined by the type of limnological type of reservoir, geographical features (climate conditions), geophysical and anthropogenic impacts. The article notes that the more diverse system of organisms is, the fuller the compounds’ decay is. This property of organisms to complement each other is called buffering of the system. Complex system of organisms cope better with organic and bacterial contamination, but is less responsive to insertion nutrients; biotic cycle in complex systems is more intense. Bacterial community plays the major role in the process of self-purification of biological marine environments. They are the major element of the coastal zone ecosystems. This article shows that during the growth of bacterial populations most of the energy supplied to the aquatic ecosystems with auto- and allochthonous organic matter is processed. The bacteria prepare the conditions for the development of other organisms of water biocenosis. Concentration of the organic substrate regulates the growth rate of bacteria. Bacterial self-cleaning depends on the total number of microorganisms or their separate groups, locally contained in the marine environment.
