The sewage treatment sedimentation tank is a common sewage treatment equipment used to remove suspended matter and sediment from sewage. It settles the solid particles in the sewage through physical and chemical effects, thereby achieving the purpose of purifying water quality. The following is a detailed introduction to the sewage treatment sedimentation tank.
1. Working principle of sewage treatment sedimentation tank
The sewage treatment sedimentation tank adopts the principle of gravity sedimentation. When sewage enters the sedimentation tank, the particles begin to settle due to the slow flow rate. Larger particles will settle to the bottom faster, while smaller particles will
suspend in the water. At the same time, the sedimentation tank can also promote sedimentation and improve the sedimentation effect by adding chemical agents.
2. Structure and composition of sewage treatment sedimentation tank
The sewage treatment sedimentation tank usually consists of the following parts:
1. Water inlet: used to introduce sewage into the sedimentation tank.
2. Sedimentation area: The sedimentation area is the core part of the sedimentation tank, which is used to precipitate solid particles. Usually, structures such as inclined plates or partitions are used to increase the sedimentation effect.
3. Water outlet: used to discharge the treated water out of the sedimentation tank.
4. Mud pump: used to extract the sludge settled at the bottom.
5. Agitator: Some sedimentation tanks will be equipped with agitators to stir the sewage and increase the sedimentation effect.
3. Operation steps of sewage treatment sedimentation tank
1. Open the water inlet valve to introduce sewage into the sedimentation tank.
2. Start the agitator (if any) to stir the sewage and increase the sedimentation effect
3. Add an appropriate amount of chemical agents as needed to promote sedimentation.
4. Wait for a while to allow solid particles to settle to the bottom.
5. Open the mud pump to extract the sludge at the bottom.
6. Close the water inlet valve to stop the introduction of sewage.
7. Open the outlet and discharge the treated water.
4. Advantages of sewage treatment sedimentation tank
1. High efficiency: The sewage treatment sedimentation tank can effectively remove solid particles in sewage and improve water quality.
2. Simple: The structure of the sewage treatment sedimentation tank is relatively simple and easy to operate.
3. Economic: Compared with other sewage treatment equipment, the investment and operation costs of sewage treatment sedimentation tanks are lower.
4.Flexible: The sewage treatment sedimentation tank can be adjusted and improved according to actual needs to adapt to different treatment requirements.
5. Application fields of sewage treatment sedimentation tank
Sewage treatment sedimentation tank is widely used in urban sewage treatment plants, industrial wastewater treatment plants, rural domestic sewage treatment and other fields. It can effectively remove suspended matter and sediment in sewage, improve water quality and reduce pollution to the environment.
01. Reasonable design and large processing capacity
The shallow pool theory design allows suspended impurities in the water to precipitate and separate the sludge, and then discharge it in a centralized manner. The laminar flow principle increases the sedimentation area.
02. Equipment automation and stable operation
The equipment effectively improves the sewage treatment capacity and impact resistance, can eliminate sludge expansion, and is easy to use and maintain.
03. Complete models and support customization
The equipment has a stable structure, and can customize and design a complete set of sewage treatment solutions according to needs and industries, with perfect after-sales service.
