What qualifications are required to design a wastewater treatment plant?

Environmental engineering (water pollution prevention and control engineering) is requiredDesign Qualifications。The design qualification is divided into Class A and Class B, and the design qualification is determined according to the scale of sewage treatment capacity.

1. Understand the basic knowledge of sewage treatment.

2. Understand the role and management methods of various structures in the sewage treatment plant.

3. Understand the distribution and use of various pipelines in the sewage treatment site.

4. Understand the meaning and application of analytical indicators in sewage treatment system.

5. Employees should have the ability to reasonably distribute water and sludge, reasonably dispatch air, correctly return and discharge sludge, and eliminate common faults in operation.

Function. The role of the sewage treatment station is to produce and domestic sewage.

Carrying out treatment to meet the specified emission standards is to protect the environment.

important facilities. industrially developed countries.

sewage treatment stations are already very common, and there are very few sewage treatment stations in villages and towns in China, but they will gradually increase in the future. In order for these sewage treatment stations to really function, they also need to rely on strict discharge systems, organization and management systems to ensure them.

Municipal comprehensive qualification; Municipal drainage professional qualification or environmental engineering (water pollution prevention and control engineering) special design qualification. Among them, the environmental design qualification is divided into Grade A and Grade B, and the requirements are: Grade B for less than 20,000 tons per day (inclusive), and Grade A for the above; It does not include pipe network and factory office buildings.

Therefore, it is best to find a comprehensive municipal qualification, and the pipe network and office building can be done together.

1. Grade A qualification for water pollution prevention and control.

1. 2 registered power supply and distribution engineers;

2. 1 registered HVAC engineer;

3. 2 registered first-class structural engineers;

4. 3 registered water supply and drainage engineers;

5. 2 budget estimation professionals;

6. 6 senior environmental protection engineers, 7. 3 intermediate environmental engineers;

8. 2 senior mechanical engineers;

9. 2 automatic control professionals.

2. Class B qualification for water pollution prevention and control.

1. 1 senior mechanical engineer;

2. 2 registered water supply and drainage engineers;

3. 1 automatic control professional;

4. 4 senior environmental protection engineers, 5. 2 environmental intermediate engineers;

6. 1 registered power supply and distribution engineer;

7. 2 budget estimation professionals;

8. 1 registered first-class structural engineer.

To sum up, a total of 23 professional and technical personnel are required for Class A qualifications and 14 for Class B qualifications. Among these specialties, automatic control, budget estimation, and some environmental professionals are required to do performance.

1. Municipal comprehensive qualification;

2. Drainage professional qualification or environmental engineering special design qualification in municipal administration;

3. Grade B environmental design qualification for 20,000 tons or less per day;

4. Grade A environmental design qualification for more than 20,000 tons per day;

5. It does not include pipe network and office buildings in the factory area.

The design of the sewage treatment station requires the "special design qualification certificate for environmental pollution prevention and control projects".
