METHOD FOR PRODUCING USE microbial biomass generated during biological waste organic compounds and their arbitrary mixtures

摘要

FIELD: chemistry.;SUBSTANCE: invention can be used in biological treatment of water, soil and similar media from organic compound contaminants of arbitrary composition and concentration, as well as when recycling organic production wastes. The method involves determination of content of organic compounds in the medium to be treated, selection of native microorganisms isolated from the treated medium, addition of the obtained mass to the treated medium with addition of macro-elements: nitrogen, phosphorus, potassium, magnesium, sulphur and trace elements: iron, zinc, manganese, molybdenum, cobalt, boron and control of physical and chemical characteristics of the treated medium. Microorganisms are selected based on the highest growth rate of biomass. Content of oxygen in the treated medium is kept between 2·10^-3 and 1.4 kg/m³ and pH is kept between 5 and 7.5. Macro- and trace elements are added based on their presence in the treated medium in total amount of (1-8)·10^-3 kg for macro-elements and 1.1·10^-7-1·10^-5 kg for trace elements per 1 MJ of complete energy of oxidation of the recycled organic compounds in an oxygen medium.;EFFECT: method enables detoxification of contaminating organic compounds to a maximum admissible concentration level and their conversion to a state which is suitable for use.;16 ex
