3 Terms and definitions
The following terms and definitions apply to this standard.
3.1 anaerobic granular sludge expanded bed reactor expanded granular sludge blanket reactor (referred to as EGSB
reactor)
Refers to the combination of gas, liquid and solid three-phase separation zones in the bottom sludge zone and the middle and upper sections, through reflow and structural design.
The effluent reactor has a higher ascending flow rate in the reactor, and the granular sludge inside the reactor is in an expanded state of anaerobic reactor.
3.2 outer loop external the circle
Refers to a cycle that will be boosted by the power of the effluent from the top three-phase separator and mixed with the incoming water.
3.3 inner loop internal the circle
Refers to a cycle in which the effluent that has not passed through the top three-phase separator is boosted by power and mixed with the incoming water.
4 Design water quantity and design water quality
4.1 Design water quantity
4.1.1 The designed water volume shall be designed according to the actual wastewater flow measured at the total discharge of the plant or industrial park. Test method should be consistent
HJ/T 91 regulations.
4.1.2 The change of wastewater flow rate should be measured according to the characteristics of the process, and the flow coefficient of variation should be determined.
4.1.3 When the actual measurement data cannot be obtained, it can be determined by referring to the current national final water consumption conversion, or according to the same
The same scale is determined by the analogy of the existing plant drainage data.
4.1.4 Lifting pump house, grille well and grit chamber should be designed according to the highest daily maximum wastewater volume.
4.1.5 The design flow rate of the EGSB reactor and the water delivery facilities such as pumps and pipelines before and after the EGSB reactor should be at the highest level.
Mean time wastewater volume design.
4.2 Design water quality
4.2.1 The design water quality should be determined according to the actual measurement data of the industrial wastewater entering the wastewater treatment plant (station), and its determination method and
The data processing method shall comply with the provisions of HJ/T 91. When there is no actual measurement data, refer to the emission data analogy of similar factories.
determine.
4.2.2 The EGSB reactor water inlet shall meet the following conditions.
