Doing this can reduce the occurrence of laboratory sewage treatment plant failures!

       During the daily experiments in the laboratory, a large amount of chemicals, such as acid, alkali and organic matter, will be consumed. If these wastewaters are discharged without treatment, they will cause serious impact and harm to the environment and human health. Mastering the treatment methods of waste liquid and waste in college laboratories is conducive to environmental protection and the development of laboratory work. The wide use of laboratory sewage treatment devices is to make the water quality of laboratory sewage treatment devices meet the national discharge standards.

In order to ensure that the use of laboratory sewage treatment equipment can achieve the expected effect and reduce the occurrence of its failure, there are some details that need to be paid attention to in the process. Let's talk about it in detail below.

The process details of the laboratory sewage treatment device:

1. Accident automatic control:

The upper limit of the liquid level of the accident pool sets the upper limit of the liquid level of the accident pool. When the liquid level is higher than this set value, the two accident lift pumps will start at the same time if they are in the automatic control position, and the liquid level of the accident pool on the computer screen will also flash to remind the on-duty personnel to pay attention; when the liquid level is lower than the accident pool It will automatically stop after the lower limit. The middle limit of the liquid level in the accident pool sets the middle limit of the liquid level in the accident pool. When the liquid level is higher than this set value, one lift pump will be started when the two accident lift pumps are in the automatic control position; when the liquid level is lower than the lower limit of the accident pool, it will automatically stop.

2. The lower limit of the accident pool liquid level:

Set the lower limit of the accident pool liquid level. When the liquid level is higher than this set value, if the two accident lift pumps are in the automatic control position, the system will automatically stop the running pumps.

3. ORP setting:

Set the redox upper limit and the upper and lower limits of acidity and alkalinity of the sewage in the contact disinfection tank. When the redox property of the sewage is greater than the set value or the acidity and alkalinity of the solution is outside the set value range, the electric valve will be opened automatically, and the sewage that does not meet the standard in the contact disinfection tank will be discharged into the accident tank for further treatment. When the redox property of the sewage is less than this set value and the acidity and alkalinity of the solution are within the range of this set value, the electric valve will be closed.
