Read this article and easily deal with the common failures of small laboratory wastewater treatment equipment!

       With the enhancement of everyone's awareness of environmental protection, the use of small laboratory wastewater treatment equipment has become very common. During the operation process, due to various reasons such as the working environment and operation methods, its technical status will inevitably undergo some changes, which may affect the equipment. performance, and even induce equipment failures and accidents. Therefore, the operator needs to have a certain understanding of its common faults and solutions, and be able to discover and eliminate these hidden dangers in time, and repair the faults that have occurred in time to ensure the normal operation of the equipment.

Tips for dealing with common failures of small laboratory wastewater treatment equipment:

1. If the pipeline system of wastewater treatment equipment is found to be leaking or cracked, it must be shut down immediately. The leaked wastewater must be completely discharged back to the advective sedimentation tank for reprocessing; the maintenance staff should be notified of the time to repair and the leakage of the pipeline should be arc welded. Plugged; if there is a fault that makes the wastewater treatment equipment unable to operate normally, the reserved wastewater storage tank should be opened immediately to prevent air pollution caused by wastewater removal. If the fault cannot be cleared in a few days, contact a truck to transport the wastewater to wastewater treatment In addition, the staff of the organization will carry out maintenance, and notify the equipment manufacturer to assign after-sales service staff to clear the fault on the spot as soon as possible, or notify the equipment manufacturer of the specific situation of the fault on the spot to facilitate professional and technical personnel to analyze the fault.

2. Abnormal water output of the equipment: check whether the pipelines of the air oxidation tank, inclined tube sedimentation tank, disinfection and sterilization tank, and sludge tank are blocked (the blockage is generally the fallen extracellular matrix and the damaged ductile three-dimensional filler ).

3. Reasons for unqualified water output: excessive water leakage, uneven hydrolysis and acidification in contact with the air oxidation tank or long-term shutdown (at this time, the extracellular matrix must be reshaped again, and there is too much sludge in the inclined tube sedimentation tank (must completely eliminate the sludge, The disinfection and sterilization equipment is stopped and the water output is not disinfected and sterilized for a long time.

4. The equipment touches the air oxidation tank, and the hydrolysis and acidification tank is uneven: check whether the gate valve at the outlet of the centrifugal fan of the hydrolysis and acidification tank is in all normal positions, and whether the aeration head is damaged.

5. The solution to the failure of the automatic control system of the equipment: check whether the switching power supply of the automatic control box is normal, check whether the sewage lifting pump and the centrifugal fan of the hydrolysis acidification tank in the supporting facilities of the buried wastewater treatment equipment are damaged (this time, electricity can be generated. If the flow is too large, the short-circuit fault power switch will be automatically cut off).

6. The actual effect of the equipment's microbial hanging film contact is not significant: check whether the hydrolysis and acidification tank of the contact air oxidation tank is symmetrical, and whether the sludge of the two hydrolysis and acidification tank is pumped to the tank. Dosing with appropriate nutrients.

If the above failure occurs in the small laboratory wastewater treatment equipment, you can try to solve it with the above methods. If it cannot be solved, you should immediately find a maintenance person to repair it. Although we cannot prevent the occurrence of these faults, we can reduce the occurrence of problems. As long as the installation work is done before using the product, problems can be found in time during use and experience methods can be summed up, similar problems can be avoided from recurring. However, it can handle and avoid common failures well, and can also make full use of the product, making the effect more obvious.
