Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to integrated sewage purification equipment. Background Art

[0002] Improve the technical defects and deficiencies of the integrated sewage purification equipment dominated by the A2 / O-MBBR sewage treatment process. At present, the treatment scale of the integrated sewage purification equipment dominated by this process is usually 5-200m 3 / d, through a large number of product applications, it is found that this process equipment is mainly used in small-scale domestic sewage treatment stations (plants). The existing technology has the following defects and shortcomings:

[0003] ① Difficulty in meeting the standards

[0004] A large number of practical applications have proved that during the operation of the A2 / O-MBBR sewage treatment process, the actual concentration of sewage varies greatly due to its small treatment scale, especially in the application of rural domestic sewage treatment. The periodic changes of sewage are relatively large, and the C / N ratio is seriously unbalanced, resulting in a high nitrogen content in the effluent. Sludge is returned in the sedimentation tank, the relative flow rate increases, the sedimentation residence time decreases, the sludge ages or denitrifies to produce nitrogen, causing a large amount of sludge in the sedimentation tank to float up, and the mud-water separation effect is poor, making it difficult for the effluent suspended matter, TN, and TP to meet the Level A standard of the "Municipal Sewage Treatment Plant Discharge Standard" (GB18918-2002). It is necessary to add deep treatment equipment, resulting in higher project investment.

[0005] ②Serious loss of activated sludge

[0006] The application of A2 / O-MBBR sewage treatment process in rural domestic sewage treatment is prone to aerobic digestion of activated sludge and deflocculation after aging due to the small treatment scale and low pollutant concentration. The sludge returns to the sedimentation tank in parallel with the effluent, the relative flow rate is too large, and the return ratio is difficult to control, resulting in the loss of activated sludge during operation. The loss amount is greater than the natural metabolism of the biofilm, which seriously reduces the effect of sewage treatment and requires regular replenishment of sewage nutrients and activated sludge.

[0007] ③ The existing equipment has weak adaptability. Currently, the scale of rural sewage treatment is relatively small (5-200m 3 / d), and the types of sewage mixed in are various, such as: a small amount of aquaculture wastewater, seasonal small amount of agricultural product processing wastewater, etc. (such as: coffee washing wastewater, walnut shelling wastewater, etc.), resulting in a large change in sewage load. The existing A2 / O-MBBR sewage treatment process technology does not take this part of wastewater into consideration, resulting in weak adaptability in practical applications, and it is easy to have unstable water production after the sewage load increases. The present invention adopts two different operation modules to address the variability of rural sewage, and has significant effects in practical rural applications.

[0008] ④ Existing equipment is difficult to transport and the investment in supporting facilities is huge

[0009] During the construction of rural sewage treatment projects, it was found that the existing A2 / O-MBBR sewage treatment process equipment has narrow village roads, large building materials and existing equipment, and difficult transportation. At the same time, there are many supporting facilities for the existing equipment, such as grille channels (wells), primary sand settling tanks, regulating tanks, sludge tanks, equipment control rooms, etc. The present invention can be modularly produced according to the actual road conditions in rural areas, and can be spliced ​​and assembled at the project site to solve the transportation problem. Through the practical application of different projects, the supporting facilities only need to consider grille channels (wells), regulating tanks, and sludge tanks, and the equipment control room is produced together with the main body of the equipment to facilitate the control and management of the equipment. At the same time, the overall investment in supporting facilities during the implementation of the project is reduced.

[0010] ⑤ Excessive energy consumption and high operating costs. The current A2 / O-MBBR sewage treatment process technology consumes about 0.7kwh / m 3 ·Sewage, all have the problems of high energy consumption, high operating costs, and difficult later maintenance. Through the improvement of the A2 / O-MBBR sewage treatment process technology route and practical proof. In the actual operation process of sludge return and nitrification liquid return, the stripping mode is adopted, and degassing and separation are carried out through a two-phase separator to avoid the energy consumption of lifting pump transportation. At the same time, it reduces the operating failure points and reduces the difficulty of later operation and maintenance. With the improved process route, the oxygen supply efficiency of the fan is increased by 20%, and reducing the output power of the fan has a significant effect on the service life and operating power of the fan, reducing operating costs. Through a large number of project practical applications, the energy consumption of the present invention is reduced to 0.55kwh / m 3 ·Sewage. Reduce the running cost of the equipment during actual operation. Summary of the invention

[0040] Working principle: First of all, the main body of the equipment is A2 / O-MBBR-N (anaerobic zone, anoxic zone, aerobic zone and high-efficiency denitrification zone), which is an in-depth improvement and optimization of the A2 / O-MBBR process.

[0041] Domestic sewage is collected and discharged into the sewage screen channel 1 through the collection pipe network. Coarse and fine screens are installed in the screen channel 1 to remove large particles of debris. The sewage flows into the regulating tank 3 by gravity, and the water quality and quantity of the sewage are homogenized in the regulating tank 3. After the sewage is fully regulated and stabilized in the regulating tank 3, it is lifted by the lifting pump to the integrated sewage purification equipment dominated by the A2 / O-MBBR-N process for sewage decomposition and treatment.

[0042] After the domestic sewage is lifted and pumped into the anaerobic section 6, the anaerobic activated sludge in the anaerobic section 6 decomposes the macromolecular organic pollutants into small molecular organic matter, methane, CO2 and other substances, and then flows into the anoxic section 7 by gravity, and the facultative aerobic bacteria in the anoxic section 7 decompose some organic matter, and then the effluent flows by gravity into the MBBR pool 8 equipped with suspended fillers 23, and the organic matter in the sewage is further decomposed into CO2, water and the like by the aerobic bacteria attached to and growing on the suspended fillers 23. At the same time, the nitrogen-containing substances in the sewage are nitrified, and the effluent is subjected to solid-liquid separation and denitrification in the high-efficiency denitrification tank 9, and the effluent is subjected to free suspended matter separation in the inclined tube sedimentation tank 10, and disinfected by the ultraviolet disinfector 14, so as to meet the Class A standard of the Pollutant Discharge Standard for Urban Sewage Treatment Plants (GB18919-2002) for discharge or resource utilization.

[0043] Among them, the nitrified liquid is returned to the anoxic tank through the low-gas-consumption stripping reflux device 26 for partial denitrification, and finally the nitrogen is removed by secondary denitrification treatment in the high-efficiency denitrification tank 9. At the same time, the sludge is returned to the anaerobic section 6 in the high-efficiency denitrification tank 9 to avoid the escape of a large amount of activated sludge due to low concentration of domestic sewage, thereby ensuring the demand for activated sludge in the process system. The free activated sludge in the supernatant effluent is separated into solid and liquid in the inclined tube sedimentation tank 10 to ensure the suspended matter content of the effluent.

[0044] The sludge in the inclined tube sedimentation tank 10 is regularly discharged to the sludge tank 12, and the sludge in the sludge tank 12 is regularly transported out for treatment or drying, and the supernatant overflows into the regulating tank 3 for re-treatment to ensure that the sewage meets the discharge standards.
