Are you doing the right thing for the use of small laboratory wastewater treatment equipment? look here!

      Small laboratory wastewater treatment equipment is widely used in residential quarters, villages, villages and towns, office buildings, shopping malls, hotels, restaurants, sanatoriums, institutions, schools, hospitals, highways, railways, Treatment and reuse of domestic sewage from factories, mines, tourist attractions, and similar small and medium-scale industrial organic wastewater such as slaughtering, aquatic product processing, and food. The water quality of the sewage treated by this equipment reaches the national discharge standard. In order to ensure that the use of the equipment can achieve the expected effect, it is necessary to operate in the correct method and maintain it regularly. Let's talk about it in detail.

1. Description of the technological process:

The laboratory wastewater is collected into the sump, and the wastewater in the sump is quantitatively lifted to the small laboratory sewage treatment equipment by the lift pump. The pH adjustment tank is equipped with an online pH detection instrument, which automatically adds acid and alkali according to the instrument signal to adjust the pH to neutral. , After that, the wastewater passes through the micro-electrolyzer, using the iron-carbon electrodes to form numerous tiny primary cells, oxidizing the iron to produce a ferrous coagulant, which has the effect of removing metal ions and other weakly negatively charged particles. Then, through the inclined tube sedimentation tank, cooperate with PAC and PAM to form precipitation and flocculation of the metal ions in the wastewater, and complete the separation of mud and water in the inclined tube sedimentation tank. emission.

2. Maintenance instructions:

1. The pipes are all UPVC pipes, and the valves are all UPVC ball valves. Therefore, when opening and closing the valve, it should be slow and light, and it is not allowed to twist or move hard, otherwise the pipe and valve will be broken.

2. When the dosing device is working normally, the cover plate should be tightly covered to prevent foreign matter from entering the liquid medicine tank.

3. To ensure the quality of the purchased agents, there should be no more insoluble sediments.

4. Regularly clean the liquid medicine tank. Every once in a while, such as a month or a quarter, the liquid medicine tank needs to be emptied and cleaned.

5. When the dosing device is not used for a long time, the medicine in it should be emptied and rinsed. At the same time, the liquid in the pump should be emptied and rinsed with clean water.

6. The equipment regularly discharges sewage according to the actual water quality.

7. The equipment regularly replaces the filter material according to the actual water quality to prevent clogging.

8. The equipment is regularly added with disinfection chlorine tablets according to the actual water quality to ensure the disinfection effect.

9. Regularly check the grounding of electrical equipment to prevent the grounding wire from loosening. During the operation of the motor, check the operation and heating of the motor frequently. If there is abnormal noise or excessive heating, it should be stopped in time to troubleshoot the fault.

In general, the correct use and regular maintenance of small laboratory wastewater treatment equipment are very critical, which can not only achieve the expected effect, prolong the service life of the equipment, but also save production costs for enterprises to achieve a win-win goal.
