Example Embodiment
[0018] Example 1:
[0019] (a) Influent: Import beer wastewater, wastewater quality COD=2480mg / L, BOD=1750mg / L, SS=390mg / L;
[0020] (b) Grid: The beer wastewater is led into the HQ rotary mechanical grid with a gap of 4mm to block large solids suspended or floating in the intercepted sewage;
[0021] (c) Solid-liquid separation: LW-350 single-motor horizontal screw discharge sedimentation centrifuge is used to further solid-liquid separation of beer wastewater;
[0022] (d) Water collection: Lead the water treated by the solid-liquid separator into the collection well to collect beer wastewater;
[0023] (e) Acid-base adjustment: The wastewater in the collection well is pumped into the effective volume of 1100m through the submersible sewage pump 3 In the adjustment tank, the mixer stirs the wastewater in the tank to prevent precipitation, and adjusts the pH of the adjustment tank with sodium hydroxide to make the pH value 7, and the adjustment tank HRT=6h;
[0024] (f) Anaerobic UASB: ...

[0028] (a) Influent: Import beer wastewater, wastewater quality COD=2500mg / L, BOD=1800mg / L, SS=330mg / L;
[0029] (b) Grid: The beer wastewater is led into the HQ rotary mechanical grid with a gap of 5mm to block the suspended or floating bulk solids in the intercepted sewage;
[0030] (c) Solid-liquid separation: LW-350 single-motor horizontal screw discharge sedimentation centrifuge is used to further solid-liquid separation of beer wastewater;
[0031] (d) Water collection: Lead the water treated by the solid-liquid separator into the collection well to collect beer wastewater;
[0032] (e) Acid-base adjustment: the wastewater in the collection well is pumped into the effective volume of 1150m through the submersible sewage pump 3 In the adjustment tank, the mixer stirs the wastewater in the tank to prevent precipitation, and adjusts the pH of the adjustment tank with sodium hydroxide to make the pH value 7.5 and the adjustment tank HRT=7h;
[0033] (f) Anaerobic UA...
