Routine maintenance in use of online BOD detector

by:BOQU     2023-04-04
The online bod detector is based on the aerobic metabolism of microorganisms to organic matter. The determination of BOD only involves the initial oxidation rate, so the determination of a sample can be completed within 8-15 minutes. The time required for the measurement is greatly shortened. It complies with the standard 'Biochemical Oxygen Demand (BOD) Microbial Sensor Rapid Determination Method for Water Quality' (HJ/T86-2002). The following is an introduction to the 6 daily maintenance items of the online BOD detector. 1. Replacement of parts. When replacing the liquid pipeline, it was found that the inside turned white and microorganisms were bred, so it needs to be replaced. Clean the flow cell once a week. Replace the microbial film once a month. Replace the Teflon membrane once a year. Replace the electrolyte once a year. 2. Replace the liquid pipeline once a week in summer and once every two weeks in winter. If it is not used for a long time, it does not need to be replaced. It mainly depends on whether there are a large number of microorganisms in the pipeline. For the pipeline connection, please refer to the schematic diagram of the flow system in Figure 4. 3. Replacing the microbial film The microbial film needs to be replaced when one of the following conditions occurs: 1. The use time exceeds 2 months. 2. Microbial poisoning. 3. After the microbial film is activated, the machine has been shut down continuously for more than one week. 4. Clean the air pump filter When the gas flow rate is adjusted to the maximum and still does not reach 0.5ml/min, it is necessary to remove the air pump, take out the filter element at the bottom of the pump, wash it with water, dry it and reinstall it. 5. Clean the flow cell Use gauze dipped in water to remove the microorganisms and other attachments in the flow cell. 6. Oxygen electrode maintenance Teflon membrane and electrolyte should be replaced once a year.
