1. Scope of application:

The A/O biochemical treatment process includes two stages: hypoxic acidization and contact with oxidation. It is suitable for life and production of wastewater in life, medicine, food and other industries. The entire processing system is m--nly composed of grids, water tank adjustment pools, aerated sand ponds, acidized pools, contact oxidation pools, two sink ponds, sludge concentration pools, fan, pumps, etc.

Its process principle:

After the sewage is removed from the large particles and fiber impurities, it flows into the adjustment tank from the pump and the acidification pool is then entered through the pump to perform acidification and hydrolysis (the mixing equipment is provided 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 adsorption and degradation function of the oxygen bacteria is used to further degrade small molecules and soluble compounds into carbon dioxide and water; then enter the second sink pool to remove peeling off The biofilm and active sludge, the water flows into the sand filter pillar filtering, the water out of the water is flowing into the pump, the pump can be pulled out of the pump, and some sludge can return the regulating tank.

2. M--n technical indicators and parameters:

1. Environmental temperature: 5 ℃ ～ 40 ℃

2. Treatment of water: 10 ～ 20L/h

3. Sewage stays in the pool: 8H

4. Staying time of two sinking ponds: 1.5 ～ 3.5h

5. Qi and water ratio: 20 ～ 40:

The tolerance coordination and technical measurement are a very important technical basic course, skills and application courses for mechanical majors. It is an important technical requirement on the design drawing of mechanical parts, and it is also an important part of the static and dynamic geometric accuracy of mechanical products. ** The development of science and technology and the improvement of production levels have also put forward increasing requirements for the geometric accuracy of mechanical products. The geometric accuracy has formed an independent technical discipline, and it is subject to the academic and engineering and technical circles. The people attach great importance to it.

This series of installations are based on the actual requirements of design engineers for the actual requirements of accuracy design, on the premise of actual teaching situation and teaching object conditions, and carefully developed a set of teaching products combining theory and reality. It is suitable for parts of ordinary high schools, employee middle schools, vocational middle schools, vocational schools and undergraduate colleges.
