Comprehensive experimental device of water environmental monitoring and governance technology

Comprehensive experimental device of water environmental monitoring and governance technology,Injector flow test experimental device

1. Product overview

The comprehensive tr--ning platform of water environmental monitoring and governance technology can meet the "water environmental monitoring and governance" opened by vocational colleges, "environmental monitoring and control technology", "environmental engineering technology", "clean production and emission reduction technology", "for giving it for Experimental tr--ning teaching in environmental related majors such as dr--nage engineering technology, and meet environmental protection standards.

The tr--ning platform should be designed with a modular combination, and at least five modules: at least the water supply process, A/O process, A2/O process, SBR process, and MSBR process. Each module should be able to tr--n independently. It can also be combined into multiple sewage treatment Comprehensive tr--ning for process. The platform should adopt a variety of control methods, which can be manually operated or automatic control. Through the tr--ning platform operation, students can evaluate students related sewage treatment system scheme selection, process design, equipment and component installation, pipeline connection, power and control line design and connection, water treatment process system system debugging and operating capabilities.

Second, system requirements

1. Good materials: The object frame is made of at least 50mm × 50mm st--nless steel square pipe material, and organic glass devices are made of at least 10mm thick blue organic glass. Using a card set connection method, other pipelines adopt a transparent PU pipeline, and the connection is connected with a fast plug -in method.

2. Convenient movement: The bottom of the device is equipped with a universal wheel with a brake.

3. Strong integrity: The reasonable distribution of all devices is fixed on the st--nless steel steel frame, and the object and control system integrated design.

4. Safety protection: It has a leakage voltage and leakage current protection device, which meets national standards; the mixer at the bottom of the steel frame is equipped with an organic glass waterproof protective cover to ensure safety operation.

5. Strong functionality: This system will modularly design the organic glass reactor. During tr--ning, selective installation can be carried out according to the corresponding functions of the organic glass reactor. It is convenient for students to design the processing process, convenient control, automatic control and CRT manual control. The electrical control cabinet wiring uses a wire plug -in connection, which is convenient and safe.
