Detailed implementation manners

[0033] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. Usually, the components of the embodiments of the present invention described and illustrated in the drawings here can be arranged and designed in various different configurations.

[0034] Embodiment 1

[0035] This embodiment discloses an intelligent and efficient microbial sewage treatment system, including a modular treatment device 1, a wood biological carrier 2, a biological culture medium and culture agent dosing system 3, and an intelligent control system 4.

[0036] The modular treatment device 1 is composed of multiple treatment units. Each treatment unit includes a treatment device body 11, an adjustable buffer space 12, a liquid level sensor 13, and a support frame 14. The treatment device body 11 is made of corrosion - resistant materials and is internally provided with a partition board 15. The partition board 15 divides the device body 11 into a water level control area 16 and a microbial reaction area 17. One side of the partition board 15 is fixedly connected to the treatment device body 11, and the other end is provided with an opening 151 for water to pass through.

[0037] The adjustable buffer space 12 is arranged in the water level control area 16, and its height can be changed through the adjusting device 18. The adjusting device 18 can be a hydraulic device, including a hydraulic lifting rod 181, a drainage part 182, and a hydraulic pump 183. The drainage part 182 is arranged at the end of the hydraulic lifting rod 181 and is within the water level control area 16. When the adjusting device 18 works, the hydraulic pump 183 pumps hydraulic oil into the hydraulic lifting rod 181, and the hydraulic lifting rod 181 drives the drainage part 182 to move up and down, and adjusts the water level height in the water level control area 16.

[0038] At the top of the main body 11 of the processing device, there is a water inlet pipe 111, and at the bottom, there is a water outlet pipe 112. The water outlet pipe 112 is arranged at a position opposite to the opening 151. The liquid level sensor 13 is installed in the adjustable buffer space 12 for real-time monitoring of the water level change. The support frame 14 is used to support the main body 11 of the processing device to adapt to complex terrains.

[0039] The woody biological carrier 2 is arranged in the microbial reaction zone 17. The woody biological carrier 2 is made of specially treated wood fiber materials and has a porous structure and a high specific surface area. The specific treatment method is as follows:

[0040] The wood fibers are broken into micron-sized particles (below 40 mesh sieve) through ball milling, grinding, etc. to reduce the fiber crystallinity and increase the porosity; by instantaneously releasing pressure of high-pressure steam (above 220 °C), the connection between hemicellulose and lignin is destroyed to form a porous structure, while retaining the cellulose skeleton. A reducing agent (such as L-cysteine) is added to the glycerol-water mixture (glycerol accounting for 20 - 80%), and it is treated at a high temperature (100 - 220 °C) for 0.5 - 2 hours. Glycerol, as a green solvent, can dissolve lignin, while L-cysteine reduces the treatment corrosivity through reduction, reduces the generation of inhibitors, and improves the subsequent enzymatic hydrolysis efficiency. Then, the hemicellulose is hydrolyzed with dilute acid (such as sulfuric acid), and the lignin is dissolved with alkali (such as sodium hydroxide) to separate the cellulose skeleton.

[0041] The woody biological carrier 2 adopts a multi-layer structure, and a certain distance is maintained between each layer to ensure uniform water flow distribution. The biological carrier 2 is fixed on the inner wall of the processing device 1 through the fixing component 21 to prevent it from shifting and accumulating under the impact of water flow.

[0042] The biological culture solution and culture agent feeding system 3 includes a biological culture solution storage tank 31, a biological culture agent storage tank 32, a feeding pump 33, and a pipeline 34. The biological culture solution storage tank 31 and the biological culture agent storage tank 32 are respectively used to store the biological culture solution and the biological culture agent. The feeding pump 33 feeds the culture solution and the culture agent into the microbial reaction zone 17 according to the set ratio and flow rate through the pipeline 34.

[0043] At the top of the main body 11 of the processing device, there is also an exhaust pipe 113. Gases such as methane generated by the anaerobic reaction in the microbial reaction zone 17 can be transported to an external gas storage device through the exhaust pipe 113 for resource treatment as a by-product. The partition plate 15 is inclined, and the opening 151 is at a lower position so that the water in the water level control area 16 can enter the microbial reaction zone from the opening 151. At the root position of the partition plate 15, there are ventilation holes 152 so that the gases generated in the microbial reaction zone 17 can be discharged upward.

[0044] The intelligent control system 4 includes a central controller 41, sensors 42, a wireless communication module 43, and a web-based monitoring platform 44. The sensors 42 include a water quality sensor, a liquid level sensor, a temperature sensor, and a dissolved oxygen sensor. The water quality sensor is disposed in the outlet pipe 112. The water quality sensor selects a HACH water quality sensor to monitor the real-time contents of COD, BOD, ammonia nitrogen, total phosphorus, etc. at the outlet pipe 112. The liquid level sensor is installed in the adjustable buffer space 12 for real-time monitoring of water level changes. The temperature sensor and the dissolved oxygen sensor are both disposed in the microbial reaction zone 17. The sensors 42 transmit data to the central controller 41 through the wireless communication module 43. The central controller 41 automatically adjusts the operating parameters of the processing device 1 according to a preset control algorithm, and realizes remote monitoring and management through the web-based monitoring platform 44.

[0045] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, should be covered by the protection scope of the present invention.
