The first water distributor 19 and the second water distributor 29 are umbrella-shaped water distributors. Taking the first water distributor 19 in the first anaerobic tower 1 as an example, the umbrella-shaped water distributor comprises a plurality of umbrella pieces 191, the umbrella pieces 191 are connected in sequence, and the whole plane of the formed umbrella-shaped water distributor is circular.

When the influent concentration of wastewater is higher, such as in a vinasse-losing period, the wastewater has low flow and high concentration, and is suitable for adopting a two-stage treatment mode, the first anaerobic tower 1 and the second anaerobic tower 2 can be connected in series, so that the anaerobic towers are in high load, and the high-concentration wastewater is treated by the 2 anaerobic towers, thereby ensuring the treatment effect of the wastewater. When the concentration of intaking of waste water is lower, such husky and husky period as, the flow height of waste water, the concentration is low, is fit for adopting single-stage treatment mode, can connect first anaerobic tower 1 and second anaerobic tower 2 in parallel, and the waste water of lower concentration is handled simultaneously to 2 anaerobic towers for the processing of waste water, single anaerobic tower can make waste water reach emission standard.
As shown in fig. 4, when the first anaerobic tower 1 is connected in series with the second anaerobic tower 2, the first anaerobic tower outlet pipe 13 of the first anaerobic tower 1 is connected with the inlet pipe of the buffer tower 3, and the outlet pipe of the buffer tower 3 is connected with the second anaerobic tower inlet pipe 210 of the second anaerobic tower 2. Specifically, the first anaerobic column outlet conduit 13 is disposed above the first upper three-phase separator 15, and likewise, the second anaerobic column outlet conduit 23 is disposed above the second upper three-phase separator 25.

The problem that the concentration of the wastewater treated by a high-load reaction area at the lower part and a low-load reaction area at the upper part of the anaerobic tower is higher and the effluent water does not reach the standard can exist because the water quality fluctuation of the Maotai-flavor liquor brewing wastewater at different stages is large. At this time, the treated wastewater needs to be subjected to reflux treatment, so that the treated wastewater obtained from the lower part and the upper part flows back at a large flow rate to dilute the wastewater inlet concentration, and the anaerobic tower has higher load impact resistance. In addition, the reflux can also adjust the pH, accelerate shearing and granulation of the sludge, and increase contact of the sludge with contaminants in the water.

It should be noted that the above reflux is only required to be started if the wastewater treated at the lower part and the upper part of the anaerobic tower does not reach the detection standard.
With the increase of the wastewater treatment time, more and more sludge is generated, and the sludge needs to be discharged after a certain amount so as to avoid excessive accumulation. Therefore, the present embodiment also requires a sludge discharge assembly at the bottom of the anaerobic tower shell.
Preferably, a first sludge discharging assembly is provided at the bottom of the first anaerobic tower 1, and the first sludge discharging assembly is provided at the bottom of the first housing 111. Similarly, a second sludge discharge assembly is provided at the bottom of the second anaerobic tower 2, and the second sludge discharge assembly is provided at the bottom of the second housing 211.

The first rotary sludge discharge pipe 112 is disposed outside the first housing, and a plurality of first inner sludge discharge pipes 113 are disposed inside the first housing 111 and connected to the first rotary sludge discharge pipe 112.

Specifically, the lengths of the first internal sludge discharge pipes 113 or the second internal sludge discharge pipes are different, and the sludge in different areas can be discharged by the first internal sludge discharge pipes or the second internal sludge discharge pipes with different lengths.
In this embodiment, part of the effluent of the lower three-phase separator enters the low-load reaction zone, part of the effluent enters the umbrella-shaped water distributor zone through the pipeline and the reflux pump, and part of the mixed liquor in the low-load reaction zone flows back to the umbrella-shaped water distributor zone, or directly discharged from the anaerobic tower to enter the next treatment link. The sludge generated in the anaerobic treatment process is firstly brought to the sludge reaction zone from the sludge zone at the bottom of the shell for anaerobic reaction, and then falls downwards from the sludge reaction zone after the anaerobic reaction and sinks to the bottom of the shell to form the circulation of the sludge. And the marsh gas enters the subsequent treatment equipment through a gas discharge pipeline arranged on the three-phase separator. In this embodiment, the portion below the three-phase separator is a sludge reaction zone, the sludge reaction zone performs anaerobic reaction between sludge and wastewater, and the generated gas is discharged upwards through a gas discharge pipe.
