Degradation device and degradation method for antibiotics in aquaculture wastewater

Abstract

The invention discloses a degradation device for antibiotics in breeding wastewater. The degradation device comprises a box body, an algae biological membrane attachment mechanism, a fixed shaft, a motor and a controller; the box body is provided with a water inlet and a water outlet along the water flow direction; the algae biological membrane attachment mechanism penetrates through the fixed shaft and is fixed on the box body through the fixed shaft; the fixed shaft is perpendicular to the water flow direction and is driven by a motor; and the motor is electrically connected with the controller. The invention further discloses a method for degrading the antibiotics in the breeding wastewater, and the method comprises the steps: employing the device for degrading the antibiotics in the breeding wastewater: preparing the algae biological membrane, and then degrading the antibiotics by utilizing the algae biological membrane. The device disclosed by the invention can rotate according to the preset time and convert the plate surface receiving illumination on the algae biological membrane attachment mechanism. On the one hand, algae can receive sunlight to promote growth and generate a large number of active substances to degrade pollutants, and on the other hand, an algae biological membrane can adsorb pollutants in lower-layer sewage to remove antibiotic pollutants in deep-layer water.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a degradation device and degradation method for antibiotics in aquaculture wastewater. Background technique [0002] At present, the excessive use of antibiotics in livestock and poultry breeding, aquaculture and other aquaculture industries is one of the main sources of residual antibiotics in sewage treatment plants and water environments. Due to the irrational use and excessive consumption of antibiotics, the concentration of residual antibiotics in the sewage and wastewater of the aquaculture industry very high. Moreover, there is currently no method, device or technology for treating antibiotic pollution in aquaculture wastewater. The sewage treated by the existing technology still contains antibiotics. In this case, it is directly discharged into the river or used for farmland recharge, which will pollute the water environment and soil, and pose a great potential ...

Moreover, there is currently no method, device or technology for treating antibiotic pollution in aquaculture wastewater

The sewage treated by the existing technology still contains antibiotics. In this case, it is directly discharged into the river or used for farmland recharge, which will pollute the water environment and soil, and pose a great potential threat to ecological security and human health.

[0003] In addition, the sewage treatment device studied at this stage is used to remove pollutants such as nitrogen and phosphorus in sewage, which is complex in design and high in cost

For example, the use of algae biofilm to remove pollutants such as nitrogen and phosphorus in sewage, specifically adopts packing static treatment, the design of the device is relatively complicated, and the degree of utilization of algae biofilm is not high, and its natural photosensitive characteristics are not used.
