Method of bod measurement and apparatus thereof |
| abstract |
In a method of measurement of BOD value of test solution by comparing dissolved oxygen decrement ΔDO of the test solution with dissolved oxygen decrement of standard solution sterilized test solution is used as the standard solution. Apparatus for conducting the above method is also disclosed. n BOD value is calculated using the measured ΔDO by a relation between 1/BOD and 1/ΔDO. n The apparatus comprises a column for contacting solution with the microorganism, oxygen electrodes disposed before and after the column for measuring the dissolved oxygen value, whereby in an inject condition, the test solution is fed to the oxygen electrode before the column and in the lead condition the test solution is fed to the oxygen electrode after the column, so that ΔDO can be measured by the two oxygen electrodes. n In the apparatus, the inject condition and the load condition are changed by solenoid valves or rotary valves. |
