Embodiment 1
[0051] The above-mentioned integrated treatment system is used to treat domestic sewage in a factory area. The concentration of chemical oxygen demand (CODcr) in the raw sewage water is 287.12mg / L, ammonia nitrogen (NH 3 -N) concentration was 29.43 mg / L, and total phosphorus (TP) concentration was 3.65 mg / L. Before entering the integrated treatment system, the domestic sewage first passes through the preset grille to remove impurities. The grille is placed in the grille pool with an inclination angle of 55°. The spacing between the grille bars is 20mm. The flow velocity of the sewage when passing through the grille is about 0.75m / s. The hydraulic retention time in the anaerobic zone of the device used in the experiment is about 12 hours, and the residence time of the stacked ecological filter bed is about 4.1 days. Sampling and testing the effluent from the outlet showed that the concentration of CODcr was 58.73mg / L (removal rate was about 79.5%), NH 3 -N concentration is 6...
Embodiment 2
[0053] Using the above-mentioned integrated treatment system to treat a rural domestic sewage, the concentration of chemical oxygen demand (CODcr) in the raw sewage water is 231.54mg / L, ammonia nitrogen (NH 3 -N) concentration was 27.31 mg / L, and total phosphorus (TP) concentration was 3.12 mg / L. Before entering the integrated treatment system, the domestic sewage first passes through the preset grille to remove impurities. The grille is placed in the grille pool with an inclination angle of 60°. The spacing between the grille bars is 20mm. The flow velocity of the sewage when passing through the grille is about 0.8m / s. The hydraulic retention time in the anaerobic zone of the device used in the experiment is about 12 hours, and the residence time of the stacked ecological filter bed is about 4.3 days. The effluent from the water outlet was sampled and tested, and the concentration of CODcr was 61.61mg / L (removal rate was about 73.4%), NH 3 -N concentration is 6.29mg / L (rem...
