Promote material to be sufficiently mixed so that material is brought rapidly up with the second driving mechanism 20 and start experience hydrolysis and acidolysis reaction.
Step 2: when temperature sensor 1, temperature sensor 2 52, temperature sensor 3 53 all reach 35 DEG C at three,
It is real to the material in anaerobic jar 1 with about 35 DEG C of hot water injection heating coil pipe 1, heating coil 2 31, heating coil 3 32
Thermostatic control is applied, the stirring rate for reducing the first driving mechanism 19 and the second driving mechanism 20 is 4r/min, so that anaerobism is anti-
Should smoothly it start.
Step 3: monitoring methane gas producing rate promotes the first driving mechanism 19 once anaerobic digestion, which enters, produces gas peak period
Rate 10r/min is sufficiently stirred material and slowly pushes material to methanogenic zone, starts the second driving mechanism 20, with every small
When stirring 10min, 3r/min frequency implement intermittent stirring.
Step 4: periodically being supplemented the material in anaerobic jar 1 that (each inlet amount is equivalent to the 1/ of 1 volume of anaerobic jar
5) squash type push, is formed, to realize continuous anaerobic fermentation, 19 rate 10r/min of the first driving mechanism is promoted, in segmented
The hot water for injecting 60 DEG C under the control of temperature control system 2 to heating coil 1, heats fresh material.
Step 5: monitoring the variation of pH sensor 2 55, pH sensor 3 56 and biogas the monitoring sensor 57 of methanogenic zone
Value needs the stirring rate 8r/min for promoting the second driving mechanism 20, under the control of segmented temperature control system 2 if pH < 6
To heating coil 2 31 controlled at 35 DEG C, heating coil 3 32 is controlled at 42 DEG C.
Step 6: when fermentor oepration at full load, since highly viscous material fluidity is poor and the gravity of methanogenic zone
Hydrolysis area, acidification region and methanogenic zone differentiation can be made more obvious with pressure, the organic loading rate of anaerobic ferment devices is promoted,
The hydraulic detention time of material shortens to about 15 days than startup stage.
