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:

1. Master the internal structure of the oxide groove;

2. Understand the hydraulic characteristics, hydraulic flow and process characteristics of oxidation grooves.

2. M--n technical indicators and parameters:

1. Environmental temperature: 5 ℃ ～ 40 ℃

2. Treatment of water: 10L/H,

3. Device shape size: 950mm × 430mm × 430mm

4. Work power: AC220V ± 10%, 50Hz, single -phase three -line system, 200W power, safety protection: have ground protection, leakage protection, overcurrent protection, protection,

3. M--n configuration:

1. 1 original water tank: white PP plate material, 10mm thick, 400 × 400 × 500mm, empty valve installed on the bottom plate, which is convenient for cleaning the water;

2. 1 water tank: white PP plate material, 10mm thick, 250 × 350 × 500mm, empty valve is installed on the bottom plate, which is convenient for cleaning the water;

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

5. Anti -corrosion improvement of 1 magnetic pump, traffic: 16 ～ 19 (L/min), r--sing: 2.7 ～ 3.4 (m) power 20W;

6. 1 aeration motor, 304 st--nless steel impeller aeration device; (power 90W, speed 2900rpm), (including 1 tone speeder),

7. Traffic measurement and adjustment: 1 rotor flow meter, (6 ～ 60L/ h)

1. Product introduction: The electric drive assembly disassembly work platform adopts BYD power to become the basis. The supporting special flipping frame connection mechanism is convenient for BYD power assembly, installation, m--ntenance and assessment, and the supporting 360 ° arbitrarily rotates and fixed flipping. The frame can analyze and detect the wear of the m--n and axis gear sets of the power assembly. The height and depth of data measurement and adjustment of the height and depth of the axis and differentials. Calculate exercises, etc.

2. Technical requirements

(1) The desktop load panel is made of 10cm thick wooden board. The panel is equipped with high -quality st--nless steel bending panels, st--nless steel, resistant to corrosion, easy to clean, uniform force, and strong load -bearing ability.

(2) The platform designs an arbitrarily flip structure between the motor and the gearbox separation screw mechanism and the gearbox 360 ° to make the power assembly light and fast. The motor and the transmission are separated without manual operation, which effectively prevents the hidden dangers of accidents during tr--ning.

(3) The oil groove is designed around the platform on the platform. When the gear disassembly, cleaning, and the installation, the oil can be directly returned to the oil collection device to keep the environment clean.

(4) The platform is supported by the upper and lower double -layer structure beams. The bearing bearing beam is made of 80*40 U -shaped profile, which is safe and stable.

(5) The platform uses steel material, which can withstand valid loads not less than 1 ton.

(6) The platform effectively solves the high -frequency skills tr--ning of students' power assembly and debugging and debugging.

(7) Place a set of sheet metal sets of disassembly parts such as gearbox gears, bearings, oil seals, and stuck springs on the platform.
