Why should dissolved oxygen be improved in water ecological restoration?

Mondo Three rural Updated on 2024-02-01

Dissolved oxygen enhancement is an important water treatment technology that is essential for the survival of aquatic organisms and the quality of the entire water body. In the natural environment, the content of dissolved oxygen can be affected by a variety of factors, such as climate, topography, hydrology, etc. In artificial water bodies, dissolved oxygen levels may be more severely affected due to human disturbances. Therefore, in order to maintain the ecological balance of the water body and improve the water quality, it is necessary to appropriately improve the dissolved oxygen.

1. The importance of dissolved oxygen.

Dissolved oxygen is the oxygen dissolved in the water body and is an important factor in the respiration and degradation of organic matter in aquatic organisms. The dissolved oxygen content in the water body plays an important role in maintaining the survival of aquatic organisms and the self-purification ability of the water body. When the dissolved oxygen content is too low, it will lead to the hypoxic death of aquatic organisms, and at the same time, the degradation rate of organic matter will be slowed down, which will cause problems such as black and odorous water. Therefore, increasing the dissolved oxygen content is one of the important measures to improve water quality and maintain the ecological balance of water bodies.

2. Reasons for the decrease in dissolved oxygen.

In artificial water, the amount of dissolved oxygen can be affected by a variety of factors. Among them, the main reason is that the content of organic matter in the water body is too high. Organic matter consumes a large amount of dissolved oxygen during the decomposition process, resulting in a decrease in dissolved oxygen content. In addition, organisms such as algae in water bodies also produce respiration and consume dissolved oxygen. In addition, factors such as the flow rate, temperature, and pH value of the water body also affect the dissolved oxygen content.

3. Methods for dissolved oxygen lifting.

In order to increase the dissolved oxygen content, a series of measures need to be taken. First of all, it is necessary to control the organic matter content in the water body and reduce the discharge of organic matter, thereby reducing the consumption of dissolved oxygen during the decomposition process. Secondly, measures such as aeration and oxygenation can be taken to increase the dissolved oxygen content in the water body. Aeration can increase dissolved oxygen by increasing the oxygen content of the water body, while aeration can directly increase the dissolved oxygen content by adding oxygen. In addition, it is also an effective way to rationally allocate aquatic plant and animal species and use their life activities to increase dissolved oxygen content.

Fourth, practical application.

In practical applications, it is necessary to select the appropriate method to increase the dissolved oxygen content according to the specific situation. For example, in urban landscape lakes, the organic matter content in the water body tends to be higher due to the impact of human activities, resulting in lower dissolved oxygen levels. In order to solve this problem, the following measures can be taken: first, strengthen water quality monitoring, timely detection and treatment of pollution sources; secondly, increase the aeration device to increase the oxygen content in the water body; Finally, plant the right amount of aquatic plants and use their growth to increase the amount of dissolved oxygen.

In addition, increasing the content of dissolved oxygen is also an important technical measure in industrial wastewater treatment. Dissolved oxygen levels can be increased by improving the process, adding aeration devices, and improving wastewater treatment efficiency. This can not only improve the effectiveness of wastewater treatment, but also reduce pollution to the environment.

V. Conclusions. Dissolved oxygen is one of the important ecological factors in water bodies, which plays an important role in maintaining the survival of aquatic organisms and the quality of water bodies. Therefore, it is necessary to take appropriate measures to increase the content of water bodies with low dissolved oxygen content. In practical applications, it is necessary to select the appropriate method to increase the content of dissolved oxygen according to the specific situation. By strengthening water quality monitoring, improving process flow and improving wastewater treatment efficiency, the content of dissolved oxygen can be effectively increased, which can contribute to maintaining the ecological balance of water bodies and improving water quality.
