Problems solved by technology

[0002] The salt contained in the water often affects its industrial application. In addition, if the salt content in the wastewater discharge is too high, it will cause environmental pollution.
There are many methods for removing salinity in water bodies. Commonly used methods include chemical methods, electrochemical methods, etc. The general process is more complicated and the cost is higher.
In the prior art, some researchers have tried to carry out desalination treatment through membrane treatment, but the effect is not satisfactory. On the one hand, because the pressure treatment is generally required, it is more complicated; on the other hand, the subsequent process is usually longer due to the low removal rate The biological treatment link makes the overall process unsatisfactory

Abstract

The invention provides an electric bioreactor for water desalination. In the technical scheme, a microporous filtration technology and a biological treatment technology are innovatively combined so as to realize the removal of salts in water, and through the improvement on components such as position and temperature control units for packing and gas distribution units, the decolorizing effect of the device on dye production wastewater is improved. According to the technical scheme of the invention, the optimization on the position of a gas distributor promotes gas-liquid mass transfer; the addition of a constant-temperature device is more convenient for temperature control in a treatment complex process; innovatively introduced inert ceramic corrugated packing has small gas resistance, and effectively avoids explosion risks possibly existing in a technological amplification process. The electric bioreactor is relatively simple in structure and low in cost; through the improvement, the treatment effect on dye production wastewater is significantly increased; the process is easy to be amplified, and therefore, the electric bioreactor has a prominent large-scale application prospect.
