Embodiment 1

[0018] Embodiment 1: The waste water is introduced into the hydrolysis and acidification tank from the adjustment tank by the submersible sewage pump, and the waste water enters the main reaction zone of the hydrolysis and acidification tank from the bottom through the diversion wall. A small amount of aeration, control DO<0.5mg / L, pH 6-7, normal temperature, residence time 6h, improve the biodegradability of wastewater, use the mud outlet at the bottom to discharge mud regularly; The overflow weir and the diversion pipe of the hydrolysis acidification tank are the water inlet of the SBR reaction tank. The water inlet time is 0.5h. 7-8, normal temperature, the SBR reaction tank is equipped with elastic three-dimensional packing and aeration device, and ammonia nitrogen degrading bacteria are added. The reaction period is 6 hours, and the sludge discharge port at the bottom of the tank is regularly discharged; the effluent of the SBR reaction tank flows into the disinfection tan...

Embodiment 2

[0019] Embodiment 2: The waste water is introduced into the hydrolysis and acidification tank from the adjustment tank by the submersible sewage pump, and the waste water enters the main reaction zone of the hydrolysis and acidification tank from the bottom through the diversion wall. A small amount of aeration, control DO<0.5mg / L, pH 6-7, normal temperature, residence time 12h, improve the biodegradability of wastewater, use the mud outlet at the bottom to discharge mud regularly; The overflow weir and diversion pipe of the hydrolysis and acidification tank are the water inlet of the SBR reaction tank. The water inlet time is 1 hour. After the water inlet is completed, it is aerated for 8 hours, allowed to settle for 1 hour, decanted for 1 hour, and idle for 1 hour. The pH is controlled at 7-8. At room temperature, the SBR reaction tank is equipped with elastic three-dimensional fillers and aeration devices, and ammonia nitrogen degrading bacteria are added. The reaction perio...

Abstract

The invention discloses a biological enhanced brewery wastewater biotreatment device, which comprises an adjusting tank (1), a hydrolytic-acidification tank (2), a sequencing batch reactor (SBR) reaction tank (3) and a disinfection tank (4) sequentially, wherein the adjusting tank is connected with the hydrolytic-acidification tank through a submersible sewage pump water inlet device; wastewater automatically flows in the hydrolytic-acidification tank and the SBR reaction tank through an overflow weir (14) and a guide pipe (15) by means of gravity; effluent of the SBR reaction tank flows into the disinfection tank through a decanter (11) and is disinfected by ultraviolet rays, and disinfected effluent reaches the standard and then is discharged; the hydrolytic-acidification tank and the SBR reaction tank are provided with fillers and aeration devices; oxygen is supplied by a blower; and the overflow weir is arranged in the hydrolytic-acidification tank. Effluent of the SBR reaction tank flows into the disinfection tank through the decanter and disinfected effluent reaches the standard and then is discharged. The brewery wastewater is treated by an anaerobic-aerobic process, and the device has the characteristics of stable running, simple operation, high treatment efficiency, low sludge yield and the like.

Description

technical field [0001] The invention relates to the technical field of industrial wastewater treatment, in particular to a treatment technology for beer industrial wastewater. Background technique [0002] The continuous development of the beer industry has brought about a continuous increase in the production of wastewater from the beer industry. Brewery wastewater mainly comes from malt workshop, saccharification workshop, fermentation workshop, filling workshop, cooling wastewater for production and some domestic sewage. It mainly contains organic substances such as sugars and alcohols. The concentration of organic substances is high and it is non-toxic. In domestic beer wastewater, the content of CODcr is 1000~2500mg / L, BOD 5 The content is 600~1500mg / L, which belongs to medium concentration organic wastewater. The wastewater has high biodegradability and contains a certain amount of Kjeldahl nitrogen and phosphorus. Beer industry wastewater is perishable, and it wi...
