Some small details needing attention in quality control experiment of wastewater and waste gas treatment
Time:2019-08-20

In waste gas and wastewater treatment, we often have to do experiments. Today, StarOne waste gas treatment will share with you the small details that need to be paid attention to in the experiment.

If the solvent is not easy to be used in the experiment, it is not easy to use the conical bottle. If the solvent is not easy to be used in the experiment, it must be recycled according to the procedure. 1. It is not easy to use the conical bottle. If it is not easy to use the conical bottle, it must be used in the experiment.

2. Sometimes the literature is not necessarily complete. When reacting according to the literature, if possible, think more. Maybe the literature is relatively simple. You might as well study and discuss it before doing the experiment.

3. Remember not to show off. If it is dangerous, but you think the difficulty is not very difficult. If you show off for a while, you may hurt yourself.

4. When doing the experiment, you can't boast. It's because you're recording the data, otherwise you don't know what to record, and the experiment will be done in vain. Don't be complacent when the experiment is successful, because it's easy to make low-level mistakes. When preparing reagent, pH value and water quality are often the reasons why the experiment is always unsuccessful.

5. When heating and refluxing with a flask to extract medicinal materials that are easy to float, the amount should be less than the general amount that can be added. Otherwise, when the liquid medicine boils, it is easy to flush the medicinal materials into the condensing pipe, thus blocking the lower part of the condensing pipe. The direct consequence is: Bang

6. We must always pay attention to observation during the experiment. Can't go away for too long.

7. Keep up with labels and records at any time. What you think you can remember will be out of the sky in two or three days.

8. When installing rubber plugs on glass pipes and condensing pipes, be careful not to use strong force. Several people around me bleed their hands for a long time because of this.

9. Carefully find the reason after each error, and don't rush to the next test until the reason is found.

10. Don't lose your temper after mistakes, which is not conducive to learning lessons.

These are some small details that should be paid attention to in the quality control experiment of wastewater and waste gas treatment. Of course, there will be other problems in the process of doing the experiment, which requires the careful attention of the experimental personnel. Finally, especially the experimental report, we must carefully sort out and save it.
