1. Source of tasks:

This sewage treatment simulation simulation experimental device.

2. Scope of application:

The A/O biochemical treatment process includes two stages: anaerobic acidization and contact with oxidation. It is suitable for the treatment of lives and production wastewater in life, medicine, food, chemical industry and other industries.

Third, its process principle:

After the sewage is removed by the grille, it flows into the adjustment pool after the large particles and fiber impurities, and then enter the anaerobic hydrolyzed acidization pool by pumping through the pump to perform acidification and hydrolysis (a mixing equipment in the pool). At this stage, the sewage is m--nly used to adjust the uniform quality of the sewage, and the characteristics of the macromolecular structure that is not easy to degrade with the characteristics of short -generation, strong activity, and easy reproduction and growth of the oxygen agonation into small molecules and soluble compounds, and initially degraded organic matter. At the same time, the nitrification effect is completed, and the pollution of nitrogen is eliminated.

Contact oxidation pool is a biological treatment device that is m--nly biofilm and has active sludge method. Through fans and oxygen aeration, the organic matter of the sewage is fully exposed to the biofilm in the pool, and the respiratory degradation function of the oxygen bacteria is used to further degrade small molecules and soluble compounds into carbon dioxide and water; The biofilm and active sludge are across the secondary contact with oxidation, so that the output of the water meets the emission standard.

The sludge in the second sinking pool is discharged into the dr--nage tank, and some sludge can return to contact with the oxidation pool. Generally, it does not require sludge back to contact with the oxidation pool. Thinking that it is a simulated device, it is likely that the biofilm does not grow well, so there is a return pump. (If you can return the flow pump normally),).

Specification (L × W × H): 1800 × 970 × 800mm

Technical structure parameters:

1) The overall steel plate structure is adopted:

Configure the drawing desktop, computer display platform, mother cabinet, locker, tool pump and keyboard pump, etc.;

2) Left and right desktop substrates:

The m--n desktop on the left adopts the standard zero (1200 × 900 × 20mm thick) to meet the national excellence. The northeast beylum thick drawing special board is used. Adjust 0-70 °, rely on your hand to twist the handle, convenient and reliable; the right desktop operates for a computer display, placing computer operations and stationery books, etc.;

3) Multiple storage space:

The lower left and right configuration tools of the desktop and the keyboard pump to meet the needs of d--ly teaching drawings and computer operations; the left side of the desktop is configured with a door storage cabinet, and the right side is configured with an open m--n cabinet for facilitation tools and hosts.

4) Stability adjustment foot pads: The bottom is used to adjust the screw foot pad or universal wheel with plastic wood levels at the bottom. It can be anti -slip and noise, and has the regulatory function to ensure the stability of the desktop and the strong structure.

M--n material specifications and surface treatment:

1) Drawing desktop brackets use high -quality torque pipe materials (30 × 60 × 1.0mm) and steel plate materials above 0.8mm; all desktop structure or component steel are national standard products, and the welding parts must be carbon dioxide protection welding process. Welded, the solder joints are firm, smooth, and beautiful, with no bubbles, burrs and leakage welding, and fake welding. They have the resistance to wear resistance and scratch. Oil removal, rust removal, and pickled phosphorus treatment to ensure that no plastic peeling and anti -rust are occurred.
