When in actual use, active sludge and macromolecular organic substances in the biochemical reaction tank are retained by using membrane separation equipment, hydraulic Retention Time (HRT) and Sludge Retention Time (SRT) can be controlled respectively, and refractory substances are continuously reacted and degraded in the reactor. On one hand, the membrane intercepts microorganisms in the reaction tank, the concentration of activated sludge in the use tank is greatly increased, so that the biochemical reaction for degrading wastewater can be performed more rapidly and thoroughly, and on the other hand, the high filtration precision of the membrane ensures that the effluent is clear and transparent, thereby omitting the secondary sedimentation tank.

Compared with the traditional biological treatment method, the method has the advantages of high biochemical efficiency, strong load impact resistance, stable effluent quality, small occupied area, long mud discharge period, easy realization of automatic control and the like.

The MBR membrane tank 430 in this embodiment has the following technical effects:

the method utilizes the dominant microorganism group (nitrifying bacteria, denitrifying bacteria, common heterotrophic bacteria and the like) in the microbial flora activated sludge, and utilizes the nutrient substances in the surrounding environment (namely organic pollutants in water) to carry out metabolism in the growth process of the microbial flora activated sludge by improving the aeration mode, the activated sludge carrier and the medium, so as to achieve the purposes of degrading pollutants and purifying water quality.

The effluent quality is high and stable, the separation effect is far better than that of the traditional sedimentation tank due to the high-efficiency separation effect of the membrane, the treated effluent is extremely clear, suspended matters and turbidity are close to zero, and bacteria and viruses are removed greatly. Meanwhile, the membrane separation also ensures that microorganisms are completely intercepted in the bioreactor, so that higher microorganism concentration can be maintained in the system, the overall removal efficiency of the reaction device on pollutants is improved, good effluent quality is ensured, and meanwhile, the reactor has good adaptability to various changes of inflow load (water quality and water quantity) and impact load resistance, and high-quality effluent quality can be stably obtained.

The process can be operated under high volume load and low sludge load, the residual sludge yield is low (zero sludge discharge can be realized theoretically), and the operation cost is reduced.

The floor area is small, the method is not limited by the setting occasions, the high-concentration microorganism amount can be maintained in the bioreactor, the volume load of the treatment device is high, the floor area is greatly saved, the process flow is simple, the structure is compact, and the floor area is saved.

Can remove ammonia nitrogen and refractory organic matters, and is beneficial to interception and growth of slow-proliferation microorganisms such as nitrifying bacteria because microorganisms are completely intercepted in the bioreactor, so that the nitrifying efficiency of the system is improved. Meanwhile, the hydraulic retention time of some refractory organics in the system can be prolonged, which is beneficial to improving the degradation efficiency of refractory organics.

In some embodiments, the effluent from the MBR membrane tank 430 enters the water production circulation tank 500, and the electrochemical oxidation device 600 in the water production circulation tank 500 directly oxidizes and indirectly oxidizes the wastewater and then discharges or recycles the wastewater.

The electrochemical oxidation apparatus 600 according to this embodiment works on the principle that the sewage flows through the electrolytic tank, and the direct current is used to abstract electrons on the anode to oxidize the organic matters or to oxidize the low-valence metal into high-valence metal ions, and then the high-valence metal ions oxidize the organic matters, so that some functional groups of the organic matters have electrochemical activity, and the structure of the functional groups is changed under the forced action of the electric field, so that the chemical properties of the organic matters are changed, the toxicity of the organic matters is weakened to disappear, and the purpose of biodegradability is enhanced.

The direct oxidation described in this example is the direct conversion of contaminants to harmless materials by anodic oxidation, and the power consumption of electrochemical oxidation is often lower than that of chemical oxidation.

The indirect electrolytic oxidation in this example refers to a process in which an organic reactant is oxidized to a desired product with an aqueous salt solution of a variable valence metal in a chemical reactor, and then the used aqueous salt solution is fed to an electrolytic cell and converted to a desired oxidizing agent.

When in actual use, the transfer station sewage generally contains a small amount of pollutants which are difficult to biochemically degrade, so that the effluent after biochemical treatment is difficult to stably reach the emission standard, and the electrocatalytic oxidation technology has high-efficiency oxidation capability, so that the pollutants which are difficult to degrade in biochemical effluent can be rapidly oxidized and degraded, and the final effluent can be ensured to stably reach the emission standard.
