With the continuous development of the aquaculture industry, aquaculture tail water treatment and water quality monitoring have become an important issue. Aquaculture tail water contains a large number of organic matter, ammonia nitrogen, phosphorus and other pollutants, if not properly treated, will cause serious pollution to the environment. Therefore, aquaculture tail water treatment and water quality monitoring are very necessary.

1.Physical treatment.
The physical treatment method is mainly to remove suspended solids and impurities in the aquaculture tail water by physical means. Commonly used physical treatment methods include filtration, sedimentation, air flotation, etc. Among them, filtration is to pass water through the filter material to intercept suspended solids and impuritiesSedimentation is the use of the density difference between suspended solids and water to make suspended solids sink to the bottom;Air flotation uses the buoyancy generated when a bubble rises to bring suspended matter to the surface of the water and then remove it.
2.Chemical treatment.
The chemical treatment method is mainly to remove the pollutants in the aquaculture tail water through chemical reaction. Commonly used chemical treatment methods include oxidation, reduction, neutralization, etc. Among them, oxidation is the use of oxidants to oxidize and decompose organic matter;Reduction is the use of reducing agents to reduce heavy metal ions into low-toxic or non-toxic substances;Neutralization is the use of acid-base neutralization reactions to adjust acidic or alkaline substances to neutral.
3.Biological treatment.
The biological treatment method mainly decomposes and transforms the organic matter in the aquaculture tail water through the action of microorganisms. Commonly used biological treatment methods include activated sludge method, biofilm method, etc. Among them, the activated sludge method is to mix microorganisms and sewage together, and convert organic matter into harmless substances through aeration, sedimentation and other processes;The biofilm method is to add biofilm to the reactor to convert organic matter into harmless substances through the action of microorganisms.
Second, the aquaculture water quality monitoring program.
1.Sampling analysis.
Sampling analysis is a method of understanding the quality of water by analyzing water samples. Sampling and analysis requires the collection and analysis of water samples from different areas and at different times to understand changes in water quality. Commonly used sampling analysis methods include chemical analysis and biological analysis. Among them, the chemical analysis method is the analysis of contaminants in water samples through chemical reactions;Bioanalysis is the analysis of contaminants in water samples through biological reactions.
2.**Monitoring.
*Monitoring is a method of real-time monitoring of water quality using technologies such as sensors. **Monitoring can realize real-time monitoring and data transmission of water quality, and timely detect and deal with water quality problems. Commonly used monitoring techniques include spectral analysis technology, conductivity measurement technology, etc. Among them, the spectral analysis technology is to understand the content of organic matter, ammonia nitrogen, phosphorus and other pollutants in water quality by analyzing the absorption and scattering of light in water samplesConductivity measurement technology is to understand the concentration of ions in water quality by measuring the conductivity of water.
III. Conclusion. With the continuous development of the aquaculture industry, aquaculture tail water treatment and water quality monitoring have become an important issue. The aquaculture tail water treatment program includes physical treatment, chemical treatment and biological treatmentThe aquaculture water quality monitoring program includes sampling analysis and monitoring. In practical application, it is necessary to select the appropriate treatment plan and monitoring plan according to the actual situation to achieve the best treatment effect and monitoring effect. At the same time, it is also necessary to strengthen technology research and development and application promotion, and improve the environmental protection level and social responsibility awareness of the aquaculture industry.
