The Use of Bioblocks at Wastewater Treatment Facilities

Summary

Results of the experimental study of development of a flow chart of wastewater treatment at distilling plants processing the grain raw material are presented. A two-stage flow chart with sludge separation at each stage is rational for such processes. The process of biochemical oxidation of organic pollutants in the course of biological treatment of concentrated wastewater of distilling plants is described the most reliably with the equations of fermentative reactions. Kinetic constants and oxidation coefficients for this type of wastewater in two-stage aeration tanks have been determined; technological parameters of aeration tanks operation up to any desired level of treatment ensuring the conditions of treated wastewater discharge have been calculated on the basis of them. Optimizing calculations have been made and technological parameters of the optimal conditions of the two-stage aeration tank operation up to indicators of complete biotreatment have been determined according to these kinetic constants determined.

Key words
