Description

Integrated bioreactor suitable for biogas slurry and wastewater treatment

Technical Field

The invention belongs to the technical field of biological culture apparatuses, in particular to the technical field of microalgae culture apparatuses, and particularly relates to an integrated bioreactor suitable for biogas slurry and wastewater treatment.

Background

In the process of biogas slurry and wastewater treatment, a biological treatment process is often involved, namely, algae or microorganisms are cultivated to absorb and convert pollutants in the biogas slurry and wastewater so as to achieve the purpose of biogas slurry and wastewater treatment. The bioreactor in the prior art mostly adopts a mode of horizontal tube culture, and the bioreactor is usually in an integral undetachable structure of a plurality of culture tubes or each culture tube is an independent module, so that the following technical problems exist in the aspects of integral structure, gas-liquid circulation, culture tube composable, process operation practicality and the like:

1. the bioreactor is easy to deform. Most of the existing bioreactors are of a horizontal tube type, and after the horizontal tube type reactors are filled with culture solution, the horizontal tube is easy to deform under the long-time action of gravity, so that the following causes: (1) the tightness of the joint part is destroyed, liquid leakage occurs, and even the danger of falling off of the transverse tube is caused; (2) the original horizontal structure is destroyed, a low-lying area appears in the middle part, liquid can not be emptied, and the cleaning difficulty is increased.

2. The gas-liquid circulation of the bioreactor is uneven. In the process of liquid flow of the transverse tube type reactor tube, the flow velocity of different horizontal planes is inconsistent, the flow velocity of the lower side of the transverse tube is low, and the generation is easy to occurThe objects are adhered to the pipe wall, and serious adhesion accumulation is easily caused by long-time culture; after the reactor is filled with gas, the gas is quickly concentrated on the upper layer, the gas-liquid contact area is small, and particularly, each culture tube is an independent module type reactor, and because each tube independently completes gas-liquid circulation, the gas-liquid flow strength is relatively small, the growth of organisms such as algae or fungus and the like is not facilitated, the effective absorption and conversion of pollutants in biogas slurry and wastewater by the organisms are limited, and the treatment of the biogas slurry and wastewater is not facilitated. Meanwhile, each culture tube is an independent module type reactor, and is not communicated with each other, so that integral gas-liquid circulation cannot be realized, and pH and CO are required to be independently developed ₂ And the dissolved oxygen and other parameters are regulated and controlled, the process is complex, the maintenance cost is high, and the large-scale biogas slurry and wastewater treatment is not facilitated.

3. The prior art bioreactor has poor detachability and assembly. The existing reactor is cumbersome to detach or not detachable after being built, and a single culture tube is inconvenient to clean. In the actual production process, the culture amount of the reactor cannot be flexibly adjusted according to the actual requirements, and the layout among all culture pipes in the reactor cannot be changed to adapt to the requirements of different sites.

4. Carbon dioxide or other gases introduced into the reactor cannot be recycled, a large amount of carbon dioxide or other gases are discharged, and resource waste is caused.

Aiming at the technical problems, the invention provides an integrated bioreactor suitable for biogas slurry and wastewater treatment.
