specific Embodiment

[0049] The start-up and commissioning device and process of the new UASB combined with ABR granular sludge reactor:

[0050] A new type of UASB combined with ABR granular sludge reactor is used to treat brewing wastewater produced from sorghum, wheat, rice, corn, dried melon, and cassava. The effective volume of the reactor for startup and commissioning is 1000m 3 , made of cylindrical carbon steel body, with an effective height of 14.8 meters. The reactor is digested and fermented at a medium temperature (34-36°C) and the insulation layer is used outside the cylinder for insulation, so as to facilitate the temperature control of digestion and fermentation in the carbon steel cylinder, and the waste water is controlled by speed regulation The constant flow pump is injected through the distributor at the bottom of the reactor, and the water from the overflow weir at the upper part of the three-phase separator enters the ABR plug-flow reaction chamber. Then it flows into a settl...

Abstract

The invention discloses a novel UASB (Upflow Anaerobic Sludge Blanket) combined ABR (Anaerobic Baffled Reactor) granular sludge reactor and relates to the field of wastewater treatment in the brewingindustry. The novel UASB combined ABR granular sludge reactor comprises a first reaction chamber, a second reaction chamber, an ABR reaction chamber, a sludge settling zone and a gas storage chamber,wherein the first reaction chamber is positioned below the second reaction chamber; an air guide sleeve is arranged at the middle of the first reaction chamber; the first reaction chamber is a diffuser speed increasing reaction chamber; the ascending velocity of liquid in the reaction chamber is far higher than that of a traditional UASB reactor, the contact between the wastewater and microorganisms is intensified, and the reaction rate is greatly improved. The invention further discloses a method for treating the wastewater in the brewing industry by using the novel UASB combined ABR (Anaerobic Baffled Reactor) granular sludge reactor. Compared with a traditional method, the method disclosed by the invention has the advantages that the treatment time is greatly shortened, the treatment efficiency is improved, and the consumption is reduced.

Description

technical field [0001] The invention relates to the field of industrial wastewater treatment, in particular to a novel UASB combined with ABR granular sludge reactor and a method. Background technique [0002] Alcohol lees and koji wine brewing wastewater are waste liquids discharged from the production of alcohol and koji wine, which contain a large amount of organic matter. The solid content is 5-6%, PH3.5-4.5, CODcr5-60,000 mg / L, BOD53-40,000 mg / L, and the main pollutants include starch, sugars, alcohols, aldehydes, esters, fibers Su and so on. [0003] The process of converting brewing wastewater into UASB combined ABR reactor from flocculent to granular sludge after pretreatment is a process restricted by extremely complex microorganisms, biochemical and physical and chemical factors. The main factors are PH value, wastewater properties, hydrolysis reaction, volumetric organic load, hydraulic load, etc. The stability of the process largely depends on the cultivation ...
