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 finally eliminated.

Contact oxidation pool is a biological treatment device that is m--nly biofilm and has active sludge method. Through fan 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 oxygen bacteria is used to further degrade the small molecules and soluble compounds into carbon dioxide and water; then enter the second sink pool to remove the 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.
