When the microporous aeration and oxygenation tube used in aquaculture is blocked, the following measures can be taken to solve it:
1、 High pressure airflow flushing method
1. Operation method:
Using a portable air compressor, remove the hose connecting the aeration tube or aeration disc and connect it to the outlet of the air compressor.
Operate the air compressor, pay attention to the aeration of the water surface, and turn off the air compressor after the status is normal.
During this process, it is important to tighten the various connections of the exposure tube with throat clamps to ensure that high-pressure airflow can smoothly flush the pipeline.
2. Attention:
Before operation, ensure that the air compressor is functioning properly and that the connecting pipes are not damaged.
During the flushing process, it is necessary to observe the aeration situation to avoid excessive flushing that may cause damage to the pipeline.
2、 Acid washing method
1. Operation method:
Pour dilute hydrochloric acid solution with a concentration of 5 into the cement pool.
Soak the blocked aeration tube in dilute hydrochloric acid solution for about 12 hours.
After removal, rinse with clean water to decompose the blockage and discharge it.
2. Attention:
Wear protective gloves and glasses during the pickling process to avoid splashing dilute hydrochloric acid on the skin or eyes.
The soaking time should not be too long to avoid corrosion of the pipeline.
The cleaned pipeline should be rinsed with clean water to avoid residual dilute hydrochloric acid from contaminating the water.
3、 Physical cleaning method
1. Operation method:
For pipelines with less blockage, a brush or high-pressure water gun can be used for cleaning.
Insert a brush or high-pressure water gun into the pipeline and scrub or flush the inner wall of the pipeline back and forth to remove dirt and microorganisms attached to the pipeline.
2. Attention:
During the cleaning process, it is necessary to avoid causing mechanical damage to the pipeline.
The pressure of the high-pressure water gun should be moderate to avoid excessive pressure causing pipeline rupture.
4、 Preventive measures
1. Regular maintenance: Regularly inspect and maintain the aeration and oxygenation pipes to promptly identify and address blockages.
2. Reasonable use: Avoid prolonged excessive use of aeration tubes to reduce wear and accumulation of dirt on the inner walls of the pipeline.
3. Water quality management: Strengthen water quality management, control the organic matter content and microbial quantity in water bodies to reduce the risk of pipeline blockage.
4. Select high-quality pipelines: Use microporous aeration and oxygenation pipes with excellent material and corrosion resistance to improve the service life and anti clogging ability of the pipeline.
In summary, various methods such as high-pressure airflow flushing, acid washing, and physical cleaning can be used to solve the problem of blockage in microporous aeration tubes used in aquaculture. Meanwhile, strengthening the implementation of preventive measures is also an important means to reduce the risk of pipeline blockage.
