Problems solved by technology

Chinese patent CN207861909U discloses an industrial beer sewage treatment device, but the device is simply a device for solid-liquid separation of sewage, and does not completely treat sewage
According to the characteristics of beer industry wastewater, select appropriate chemical and biological treatment agents to combine, so that the treatment agents can absorb metal ions and other substances in the precipitation wastewater to treat beer waste liquid, but it needs to add a lot of treatment agents, and different beer The wastewater produced by the brewing production line is not the same, so this cannot be adapted to different beer waste liquids with different trace components

Embodiment 1

[0041] Further explanation in conjunction with accompanying drawings: as Figure 1 to Figure 8 The shown beer waste liquid biological treatment device, including impurity removal device ( figure 1 ),heating equipment( figure 2 ), anaerobic treatment unit ( image 3 ), biological contact oxidation chamber ( Figure 4 and Figure 6 ), filter adsorption chamber ( Figure 8 ) and membrane bioprocessing chamber ( Figure 7 ).

[0042] The impurity removal device described in this embodiment is provided with two, one is used to pretreat high-concentration waste liquid, and the other is used to treat low-concentration waste liquid. Each of the impurity removal devices includes a liquid inlet pipe 101, Liquid outlet 102 of impurity removal device, inner filter tank 103, outer rotary filter tank 104, inner tank side slider 105, outer tank side slide 106, inner tank top wall 107, inner tank bottom clamping block 108, outer tank bottom Clamping block 109, impurity removal device ...

Embodiment 2

[0050] The difference between this embodiment and embodiment 1 is that, as Figure 5 As shown, the scope of the oxygen-enriched chamber is further expanded to perform oxygen exposure treatment on a part of the first packing frame, that is, the oxygen-enriched chamber can further enable a part of the first packing frame to turn in and out during the rotation process. .

Embodiment 3

[0052] The flow of high-concentration waste liquid in the waste water flow of a brewery is 1000m 3 / day, the flow rate of low-concentration waste liquid is 3000m 3 / day, the beer waste liquid biological treatment method that adopts the beer waste liquid biological treatment device of embodiment 1 to carry out, concrete steps comprise:

[0053] (1) put a figure 1 The inner filter tank of the impurity removal device slides downward in the outer tank side slideway through the inner tank side slider, and the inner filter tank is clamped to the outer rotation through the clamping block at the bottom of the inner tank and the clamping block at the bottom of the outer tank. Inside the filter tank (the clamping block at the bottom of the inner tank and the clamping block at the bottom of the outer tank only limit their position by clamping, and the inner filter tank is not loaded, and the load bearing of the inner filter tank is carried out by the top wall of the inner tank), at thi...

Abstract

The invention relates to a beer waste liquid biological treatment method. The beer waste liquid biological treatment method adopts a beer waste liquid biological treatment device which comprises an impurity removal unit, a heating unit, an anaerobic treatment unit, a biological contact oxidation chamber, a filtration adsorption cavity and a membrane biological treatment cavity. Each specific unitis specifically set, so highly-efficient impurity removal is realized; through reinforcement of anaerobic and aerobic treatment, the treatment efficiency of a beer waste liquid is improved; through specific limiting of all steps, different processes are adopted for the beer waste liquid from different sources, so unnecessary consumable waste is avoided, and the treatment efficiency of a water bodyis improved.

Description

technical field [0001] The invention relates to the field of beer waste liquid treatment and belongs to the field of environmental protection, in particular to a biological treatment method for beer waste liquid. Background technique [0002] The beer brewing industry is a big water consumer. Generally, it takes 8 to 15 cubic meters of water to brew one ton of beer. Therefore, the beer brewing industry is also a big waste water discharger. Beer brewing waste liquid is a medium-concentration organic waste liquid, and its wastewater indicators are roughly: pH value 5-6, COD Cr 2500~3500mg / L, TN 30~90mg / L, TP 5~7mg / L, BOD 5 1500~2000mg / L, SS 800~1200mg / L, the waste liquid is not toxic, but because it contains a lot of organic matter, if it is directly discharged, it will cause the water body to lack oxygen, and a large number of microorganisms will cause the water body to become black and smelly. For the treatment of beer brewing waste liquid, the main thing is not to remove ...
