I. Requirements for Influent Water Quality & Quantity and Effluent Discharge of Sewage Treatment System
The data indicators are shown in the following table for requirements for Influent Water Quality & Quantity and Effluent Discharge of Sewage Treatment System
| Number | Item | Highly concentrated sewage data | Comprehensive sewage data | Emissions requirements data |
| 1 | CODcr | 12000mg/L | 3000mg/L | ≤500mg/L |
| 2 | BOD5 | 5000mg/L | 1000mg/L | ≤200 mg/L |
| 3 | NH3-N | 100mg/L | 50mg/L | ≤50mg/L |
| 4 | SS | 1000mg/L | 1000mg/L | ≤400 mg/L |
| 5 | PH | 6～9 | 6～9 | 6～9 |
| 6 | Water capacity | 3000m3/d | 12000m3/d | 15000m3/d |
II. Process of Sewage Treatment System
The process of sewage treatment system is briefed as follows:
III. Process Description
The highly concentrated sewage enters the highly concentrated sewage regulation tank to adjust the water quality & quantity and to mix evenly. The sewage in the regulation tank enters the hydrolysis acidification reaction tank for hydrolysis acidification reaction and precipitation separation. After temperature regulation, the effluent enters the anaerobic biochemical reactor for anaerobic biochemical reaction and precipitation separation. The anaerobic effluent enters the integrated sewage regulation tank and is adjusted with the integrated sewage to mix evenly.
The sewage in the integrated sewage regulation tank enters the anaerobic biochemical reaction tank for anaerobic biochemical reaction, and the effluent enters the CASS biochemical reaction tank for anaerobic aerobic combined biochemical reaction and precipitation separation, and the effluent discharge meets the standard.
