Method for directly measuring quantity of biodegraded organic matter of biological active carbon

Abstract

The invention discloses a method for directly measuring the quantity of a biodegraded organic matter of biological active carbon. The method comprises the following steps of: at a normal temperature, adding the biological active carbon to be measured and experimental water into a closed reactor; then aerating from the bottom of the closed reactor by using pure oxygen gas; measuring and recording the concentration of carbon dioxide in an air exhaust device of the closed reactor; then draining the liquid in the closed reactor and reserving the biological active carbon; adding the other group of experimental water with the volume which is the same as that of the added experimental water into the closed reactor; aerating from the bottom of the closed reactor by using pure nitrogen gas; measuring and recording the concentration of the carbon dioxide in the air exhaust device of the closed reactor; by using an integral of a product of a gas supply amount and the concentration of the carbon dioxide in a period of time, respectively calculating the generation amounts of carbon dioxide obtained by aerating through the pure oxygen gas and the pure nitrogen gas in a certain period of time; and calculating a generation amount of the biodegraded organic matter carbon dioxide of the biological active carbon by using a difference value and then calculating the quantity of the biodegraded organic matter of the biological active carbon. The method provided by the invention has the advantage that the quantity of the biodegraded organic matter of the biological active carbon can be directly measured.

Description

technical field [0001] The invention relates to the technical field of measuring the biodegradable organic matter amount of biological activated carbon, specifically, a method for directly measuring the biodegradable organic matter amount of biologically activated carbon. Background technique [0002] The biological activated carbon process in wastewater treatment technology can efficiently remove organic matter, and can also be combined with other processes to achieve better treatment results.

The removal of organic matter in wastewater by bioactivated carbon is a combination of microbial degradation and activated carbon adsorption. Accurate determination of the amount of biodegraded organic matter in the process of bioactivated carbon removal of organic matter is the key to evaluating the activity of bioactivated carbon and understanding the mechanism of bioactivated carbon removal of organic matter. However, there has been no To find a direct measurement method for the biodegradation of organic matter by bioactivated carbon, the existing technology mainly relies on indirect speculation, and the error of indirect speculation has seriously affected the understanding of the mechanism of bioactivated carbon to remove organic matter

The research on the mechanism of biological activated carbon to remove organic matter is at the bottleneck, which restricts the application of this process and the development of other combined processes
