LABII reagent, like many factories, can be realized if COD, ammonia nitrogen, total phosphorus and total nitrogen are measured. The data is also more accurate. These are also the most commonly tested items in sewage treatment plants.
These projects are all right, and there are no occupational diseases. But if you are busy every day, you will have other things, nervous.
Pay attention to rest at work, it will get better and better ~

What are the sewage treatment experiments? Laboratories in sewage treatment plants generally do very basic biochemical experiments, such as measuring BOD5, COD, SS, ammonia nitrogen and so on. You need to determine what instruments you need according to the items you test, and which items are the most basic. You can find a way to measure them. For example, you can choose COD online monitoring, which is very convenient. Of course, the instrument is expensive, and you can also choose the common digestion titration method (reflux condenser tube, electric furnace, hob table). This mainly requires some chemical glassware and equipment. Microscope is also necessary, and it is often necessary to examine the sludge under microscope. Atomic absorption spectrophotometer is also needed for metal ion analysis.
