Embodiment 1
[0028] The treated sewage water quality is as follows: COD cr 500mg / L, BOD 5 150mg / L, SS≤200mg / L, NH 3 -N≤100mg / L, T-P≤5mg / L, pH=6.5-9.0.
[0029] The treated effluent quality is as follows: COD cr 50mg / L, removal rate over 90%, BOD 5 10mg / L, the removal rate is above 93.3%, SS≤10mg / L, the removal rate is above 95%, NH 3 -N≤8mg / L, the removal rate is above 92%, T-P≤1mg / L, the removal rate is above 80%, pH=6-9.
[0030] The specific treatment is as follows:
[0031] 1. Pretreatment: Send the sewage from the sump to the mechanical grille, and control the flow rate of the screen to 15000-35000m 3 / d, remove the large particles and fiber impurities, and then send it to the grit chamber, control the flow rate in the canal to 0.9m / s, and the residence time is 30s, remove the sand particles with a specific gravity of 2-3 and a particle size above 0.2mm, and send the sewage into the In the primary sedimentation tank, the sedimentation time is controlled for 1.8 hours, the sewag...

[0039] The treated sewage water quality is as follows: COD cr 400mg / L, BOD 5 100mg / L, SS=180mg / L, NH 3 - N = 90 mg / L, T-P = 3.8 mg / L, pH = 6.5.
[0040] The treated effluent quality is as follows: COD cr 55mg / L, BOD 5 11mg / L, SS=12mg / L,, NH 3 -N=9 mg / L, T-P=1 mg / L, pH=9.
[0041] The specific treatment is as follows:
[0042] 1. Pretreatment: Send the sewage from the sump to the mechanical grille, and control the flow rate of the screen to 15000-35000m 3 / d, remove the large particles and fiber impurities, and then send it to the grit chamber, control the flow rate in the canal to 0.9m / s, stay for 30s, remove the sand particles with a specific gravity of 2-3 and a particle size above 0.2mm, and send the sewage into the In the primary sedimentation tank, the sedimentation time is controlled for 1.8 hours, the sewage is sent to the biochemical system, and the sand residue is discharged into the sand residue tank;
