ABSTRACT

Results of the study of the role of sandy bottom sediments in the processes of self-purification of water from organic matter are presented. It has been found that in sandy bottom sediments the rate of the decrease in the value of BODtotal is essentially higher than that registered in the water without sandy bottom sediments (especially during the short-term exposition). The coefficient of purification was proposed for the quantitative assessment of the capacity of sandy bottom sediments for purification. It makes it possible to assess the decease in the value of BODtotal as a result of the joint action of physical, chemical, and biological processes occurring in sandy bottom sediments.
