Integrated sewage treatment

Integrated sewage treatment equipment is widely applied in various fields and offers numerous advantages, operating based on specific principles.

Applications:

1. Domestic sewage treatment: It is suitable for treating sewage in rural areas, residential communities, and scattered households. For example, in rural areas with no centralized sewage treatment system, this equipment can effectively handle domestic wastewater containing kitchen waste water, toilet sewage, etc.

2. Industrial wastewater treatment: Applicable to industries such as food processing, textile, and printing. For instance, in food processing plants, it can deal with wastewater rich in organic matter.

3. Hospital sewage treatment: Capable of treating sewage from hospitals, which may contain pathogens and harmful substances, ensuring the sewage meets the discharge standards.

Advantages:

1. Compact structure: Occupies less space, making it suitable for areas with limited land resources. It integrates multiple treatment units into one device, reducing the overall footprint.

2. High degree of automation: Equipped with automatic control systems, it can operate continuously with minimal manual intervention, saving labor costs and ensuring stable operation.

3. Good treatment effect: Combining multiple treatment processes, it can efficiently remove various pollutants, including organic matter, nitrogen, phosphorus, and suspended solids, to achieve high-quality treated water that meets the discharge standards.

4. Easy installation and maintenance: Modular design allows for quick installation at the site. And its simple structure makes maintenance relatively easy, reducing the maintenance workload.

Principles:

1. Physical treatment: Through processes like filtration and sedimentation, suspended solids and large particles in the sewage are removed. For example, grids can intercept large debris, and sedimentation tanks allow heavier particles to settle.

2. Biological treatment: Utilizes microorganisms to decompose and oxidize organic matter in the sewage. In aerobic environments, aerobic bacteria consume organic pollutants, while in anaerobic environments, anaerobic bacteria break down complex organic substances into simpler ones.

3. Chemical treatment: Sometimes, chemicals are added to the sewage to precipitate or react with certain pollutants. For example, adding flocculants can help aggregate fine particles for easier removal.

In conclusion, integrated sewage treatment equipment plays an important role in environmental protection by providing an efficient and practical solution for sewage treatment.
