A new technology of processing of bioremediation with obtaining energy carriers while simultaneously clearing sewage from fish farms with a closed cycle of water supply has been developed. A closed cycle of waste processing has been created, in which at each stage the necessary association of microorganisms is selected. The purification of sewage from biogenic elements is proposed with the help of microalgae, the metabolism of which is guided by change for the purpose of increased release of triacylglycerols (raw materials for biodiesel fuel production).
Scientific and technological bases of renewable raw materials conversion in biohydrogen and biomethane were grounded; conditions of increasing of renewable raw materials conversion rate and energy production in the enzymatic separation process into two stages were defined. Rational technological parameters stages were determined. This allows forming highly effective microorganisms associations that are able to maximize the rate of different raw materials conversion and halve its duration. Rational technological parameters of biohydrogen (biomethane) obtaining were defined.
