[0019] A. Sequencing batch ASB reactor 4:
[0020] Sequencing batch ASB reactor 4 is reformed from the original UASB reactor. The specification is φ×H=18×120cm, the total volume is 30L, the effective volume is 22.9L, the ratio of height to diameter is 6.67:1, and it is made of PVC pipe. After reforming, the reactor 4 maintains the original water seal, water distributor and air chamber. There are two changes, one is that the original water outlet pipe is changed from the top of the reactor 4 to the bottom of the air chamber, 65cm away from the bottom of the reactor 4, and 55cm away from the top; the other is that the operation mode is changed from continuous water inlet to intermittent sequential batch feeding Water and digestive juice are drained after standing and settling, which is more conducive to the separation of gas, liquid and solid, and can maximize the amount of sludge in the reactor 4.
