1. Experimental purpose:
1. Deepen the understanding of this process for "printing and dyeing wastewater" or other wastewater.
2. Master the performance and test technical data of this process operation, and use reliable data in production.
3. Enable operators to improve theoretical and practical knowledge.
2. Experimental principle:
This device adopts A/O biochemical treatment process, which is anoxic acidification and contact oxidation.
After the sewage is removed by the grid radish, it flows into the water distribution tank by gravity (the large amount of water can be stirred by the fan), and then it is pumped and metered into the acidification tank for acidification and hydrolysis. This stage m*nly makes the sewage homogenous. And by using the characteristics of short generation, strong activity and easy reproduction and growth of facultative anaerobic bacteria, the macromolecular structure organic matter that is not easy to degrade is hydrolyzed into small molecules and soluble compounds, the organic matter is initially degraded, and the denitrification is completed at the same time, and the nitrogen pollution is finally eliminated.
The contact oxidation tank is a biological treatment device that m*nly uses the biofilm method and also has the activated sludge method. Through oxygenation and aeration by fans, the organic matter in the sewage is fully in contact with the biofilm in the tank, and the adsorption and degradation functions of aerobic bacteria are utilized to further degrade small molecules and soluble compounds into carbon dioxide and water. The sewage then enters the vertical flow secondary sedimentation tank to remove the flaked biofilm and activated sludge so that the effluent can meet the discharge standards.
