What are the occupational diseases of sewage treatment

Sewage treatment, if the water contains hazardous substances, there will be some reactions related to long-term exposure to hazardous substances.

Like many factories, if you measure COD, ammonia nitrogen, total phosphorus, total nitrogen, LABII reagent can be realized. The data is also more accurate. These are also the most common test items in the sewage treatment plant.

These items are fine, there is no occupational disease. But if every day is very busy, then there will be other, labor injury.

Work at the same time pay attention to rest, you will be more and more good Oh ~

What are the experiments in sewage treatment

sewage treatment plant laboratories generally do is very basic biochemical experiments, such as measuring BOD5, COD, SS, ammonia, etc., to be tested for your project to determine what you need to instrumentation, which items are the most basic, you can find out what method of determination, such as COD you can choose online monitoring so convenient, of course, the instrument is more expensive! For example, COD you can choose online monitoring, which is very convenient, of course, the instrument is more expensive, you can also choose the ordinary digestion titration method (reflux condensation tube, electric furnace, iron stand, bottles and cans and whatnot, acid and alkali burette, electronic balance, the necessary pharmaceuticals, and so on). This mostly requires some glassware and equipment for chemistry. A microscope is also necessary, and is often needed to do sludge microscopy. Atomic absorption spectrophotometer if you do metal ion analysis is also needed.
