What are the process details in the design of the laboratory sewage treatment plant?

       Nowadays, in order to meet the requirements of green environmental protection, the discharge of sewage also needs to meet relevant requirements, especially laboratory sewage, due to its complex composition, especially the lead, mercury, cadmium, hexavalent chromium, copper, antimony, divalent Heavy metals such as iron, aluminum, and manganese, as well as a large number of pathogens such as bacteria, viruses, and eggs, have been widely used in laboratory sewage treatment devices to solve this problem. In the design of laboratory sewage treatment equipment, there are some well-designed process details that can make the use of the equipment safer and more effective. Let's analyze it carefully.

Details of the process design of the laboratory sewage treatment plant:

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 of the accident pool is to set the middle limit of the liquid level of 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.

The above are some carefully designed process details when the laboratory sewage treatment device is used, hoping to help you better understand the product.
