Urban sewage treatment oxidation ditch training device

When the oxidation groove is used to treat urban sewage, the first sedimentation tank may not be provided. The suspended organic matter can be oxygen and stable in the oxidation groove. This is more economical than setting up a sludge stability system for setting up a sedimentation tank and a separate device. However, in order to prevent the accumulation of inorganic sediment in the oxidation groove, the original sewage should be pre -processed by the grille and the sand pool. Oxidation sulcus structure and process process. This device is a teaching experimental equipment for oxidation grooves. Through the hope of this experiment, the following goals are achieved:

3. 1 set of paddles from the original water tank mixing motor, 304 st--nless steel mixing paddle; (power 25W, speed 120rpm), (including 1 tone speeder)

4. 1 set of single sulcus oxidation grooves, transparent and organic glass materials, wall thickness 10mm, 600 × 350 × 350mm, aeration device

1. Product overview

This device is a comprehensive test equipment that is widely used in scientific research, teaching and production, covering PLC control technology, touch screen operation technology, hexagonal concrete test technology, automatic control technology, liquid level monitoring technology, water sample tr--ning Technology, wastewater treatment recycling technology, energy conservation and environmental protection technology, anti -cleaning technology, temperature measurement technology, software analysis technology, etc., students conduct concrete tests through test devices, select the best types of concrete, and determine the optimal amount. The best stirring speed and time can be determined through the selection or modification of the PLC control program, which can meet the "Water Pollution Control Engineering", "Environmental Engineering", "Experimental Water Treatment Experimental Technology", "Industrial Water Treatment Engineering", and "practical wastewater treatment The tr--ning and teaching of curriculum such as technology can also meet the tr--ning and use of related skills competitions.

Second, systemic characteristics

1. The framework is made of 38 × 38mm st--nless steel square tube material with a thickness of 1.5mm; the water tank is made of light blue transparent organic glass; the entry and exit water pipes are convenient for the st--nless steel composite tube and silicone pipes, which is convenient to connect.

2. Strong security: equipped with a separate power control cabinet, equipped with leakage protectors and grounding signs to ensure the safety of the equipment.

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

4. Strong functionality: The device uses PLC programming control, touch screen operation method, with automatic water inlet and dr--nage device, circulating stirring device, with synchronization and asynchronous operation. The mixing head automatically lifts, the beeurine reminder, automatic water measurement, automatic calculation of G and GT values and other functions. At the same time, there is also a filter device, which can be separated from flocculent bodies and wastewater recycling. There are 24 routes running indicators, 6 sets of liquid level controllers, and platform water connection systems.
