when the sewage flowing into the raw water tank 201 is organic matter (such as domestic sewage including dish washing, floor wiping and the like) with small molecules and easy degradation, the upper computer controls the flow control valve I23 to be opened and the flow control valve II 24 to be closed, so that the water enters the solid-liquid separator 202 through the raw water tank 201 to be subjected to solid-liquid separation, the supernatant on the upper part of the solid-liquid separator 202 enters the sedimentation tank 211 through the overrun pipe 22 to be continuously subjected to solid-liquid separation, and the supernatant on the upper part of the sedimentation tank 211 enters the plurality of branch pipelines 26 through the main pipeline 25 to enter the corresponding SBR reactor 2 to be subjected to aerobic reaction. When the sewage flowing into the raw water tank 201 is organic matter with macromolecule difficult degradation (such as garbage percolate, livestock breeding wastewater and other high-concentration organic wastewater), the flow control valve I23 is controlled to be closed through the upper computer, and the flow control valve II 24 is controlled to be opened, so that the sewage directly passes through the anaerobic reactor 1 for anaerobic reaction, then passes through the solid-liquid separation of the sedimentation tank 211, and enters the SBR reactor 2 for aerobic reaction.
Meanwhile, biogas generated in the anaerobic reactor 1 is recycled through a biogas recycling device 15, sludge deposited at the bottoms of the solid-liquid separator 202, the sedimentation tank 211 and the plurality of SBR reactors 2 enters a sludge concentration tank 3-1 through a sludge discharge pipeline, and then is processed by a plate and frame filter press 3-2 to form sludge cakes, so that organic fertilizer can be manufactured, secondary utilization of resources is realized, and supernatant liquid at the upper parts of the sludge concentration tank 3-1 and the plate and frame filter press 3-2 is injected into the anaerobic reactor 1 through a lifting pump for further cyclic processing.
Meanwhile, the temperature sensor detects the reaction temperature in the anaerobic reactor 1 in real time, and the heating temperature of the anaerobic reactor 1 is adjusted by controlling the water bath 6 through the control cabinet 5, so that the reaction temperature in the anaerobic reactor 1 is in a proper range; the liquid level sensor can detect the reaction liquid level in the anaerobic reactor 1 and the SBR reactor 2 in real time, and the control cabinet 5 prevents the problem of poor anaerobic and aerobic reaction effects caused by overhigh or overlow liquid level by controlling the flow control valves arranged at the sewage inlets of the anaerobic reactor 1 and the SBR reactor 2; the dissolved oxygen analyzer detects dissolved oxygen in the SBR reactor 2 in real time, and the control cabinet 5 controls the aeration device 19 to introduce a proper amount of oxygen into the SBR reactor 2, so that aerobic reaction is more sufficient, and the aerobic degradation effect is further improved; the PH meter and the oxidation-reduction potentiometer detect the PH and the oxidation-reduction potential in the aerobic reaction and the anaerobic reaction in real time, so that the states of the anaerobic reaction and the aerobic reaction can be observed conveniently in real time.
