III. Product Principle

Microorganisms consume oxygen in the culture bottle, producing carbon dioxide. The carbon dioxide is absorbed by quicklime, which reduces the pressure in the culture bottle, creating a pressure difference across the manometer. This connects the electrolytic circuit, causing the copper sulfate solution in the electrolytic bottle to electrolyze and produce oxygen, which is then replenished into the culture bottle, gradually restoring the pressure to its initial level. The amount of electricity passed into the electrolytic bottle is directly proportional to the oxygen produced. A coulometer accurately monitors the amount of electricity passed into the electrolytic bottle, thereby calculating the oxygen consumption. The ratio of actual oxygen consumption to theoretical oxygen consumption is the biodegradation rate of the tested sample.

VI. Typical Case Studies

This shows the results of a certain unit using the T9000C electrolytic respiration biodegradation instrument, according to the GB/T   19276.1-2003 standard method, to determine the biodegradability of a certain sample. The experimental period was 59 days. At the end of the experiment, the degradation rate of cellulose was 89.53%, the curves of each sample group were smooth, and the growth was basically complete. The experimental design and experimental result curves are shown below:
