Description

Technical Field

[0001] This invention relates to the field of microbial culture equipment technology, specifically to an operating environment simulation device for the resuscitation of nitrifying bacteria. Background Technology

[0002] The operating environment simulation device for nitrifying bacteria resuscitation is a key auxiliary device in the activated sludge process for wastewater treatment. Its core function is to replicate the actual operating environment of the wastewater treatment system, providing suitable resuscitation conditions for dormant nitrifying bacteria, and solving problems such as slow nitrifying bacteria resuscitation, easy loss with effluent, and low utilization efficiency in traditional direct addition methods.

[0003] The simulation device mainly consists of a simulated reaction vessel, a parameter control system, and a monitoring module. Dormant nitrifying bacteria, wastewater samples, and activated sludge are introduced into the device. The control system sets operating parameters consistent with those of the wastewater treatment system to create a suitable physicochemical environment for bacterial reactivation, promoting rapid bacterial activation and attachment to bacterial flocs. At the same time, water quality monitoring verifies the reactivation effect and pollutant treatment capacity, providing data support for actual addition.

[0004] However, the above-mentioned equipment has certain shortcomings in use. Traditional devices mostly rely on manual sampling to detect core parameters such as pH, dissolved oxygen, and temperature. The detection interval is too long, the parameter feedback is lagging, and the operating conditions cannot be adjusted in time, resulting in large fluctuations in the nitrifying bacteria recovery environment. In view of this, we propose an operating environment simulation device for nitrifying bacteria recovery. Summary of the Invention

[0014] In a further embodiment, multiple sets of spoilers are provided, with the multiple sets of spoilers positioned below the conical plate, and the circular plate vertically mounted on the circular rod.

[0015] In a further embodiment, the round rod and the round plate are positioned directly below the conical plate.

[0016] Compared with the prior art, the present invention provides an operating environment simulation device for the resuscitation of nitrifying bacteria, which has the following beneficial effects: 1. This operating environment simulation device for nitrifying bacteria resuscitation is designed to meet the core requirements of efficient nitrifying bacteria resuscitation. It incorporates a simulation component that, along with inlet and outlet pipes, controls water flow via valves. This allows for the introduction of wastewater or the replenishment of carbon sources and alkalinity, mimicking the actual operating conditions of a wastewater treatment system. The detection module's pH meter, dissolved oxygen meter, and thermometer monitor key parameters in real time via detection rods. Heating equipment controls temperature, and the air inlet pipe supplies air evenly to multiple aeration pipes via a distribution pipe, rapidly adjusting dissolved oxygen levels. The bottom filter plate carries activated sludge, and inclined plates guide water flow to ensure full contact with the sludge. A limiting cylinder secures the air inlet pipe, ensuring stable aeration.

[0017] 2. The operating environment simulation device for nitrifying bacteria resuscitation provides a stable temperature environment for nitrifying bacteria by setting up auxiliary components. These components work with a motor to drive the propeller to rotate. After impurities are filtered through a circular filter plate, a directional water flow is formed. The triangular guide plate guides the water flow to diffuse, avoiding local hypoxia or uneven parameters. The inclined cylinder and sealed pipe ensure stable propeller operation and prevent sludge deposition caused by water flow impact.

[0018] 3. This operating environment simulation device for nitrifying bacteria resuscitation is equipped with a stirring component to significantly reduce operating costs and the risk of loss. This component, in conjunction with a servo motor-driven rod, rotates a conical plate, a baffle plate, and a circular plate. Multiple baffle plates break the laminar flow of water, creating turbulence and promoting contact between nitrifying bacteria, activated sludge, and nutrients. The circular plate and rod stir at the bottom to prevent sludge from settling at the bottom of the tank. Combined with the aeration effect of the aeration pipe, this further improves the dissolved oxygen transfer efficiency. Attached Figure Description

[0023] Please see Figures 1-8 The present invention provides a technical solution: An operating environment simulation device for the resuscitation of nitrifying bacteria includes a box 1, with a base 2 fixedly installed at the bottom of the box 1.

[0024] In one embodiment of the present invention, a simulation component 3 is provided on the housing 1. The simulation component 3 includes a water outlet pipe 31, which is fixedly installed below the side wall of the housing 1. A water inlet pipe 32 is fixedly installed above the side wall of the housing 1. A mounting bracket 33 is fixedly installed on the housing 1, and a detection module 34 is provided on the mounting bracket 33. An inclined plate 35 is fixedly installed at the bottom inner side of the housing 1, and a bracket 36 is fixedly installed on the inclined plate 35. A bottom filter plate 37 is fixedly installed on the bracket 36. A limiting cylinder 38 is fixedly installed on the inner wall of the housing 1, and an air inlet pipe 39 is snapped onto the limiting cylinder 38. A diversion pipe 310 is fixedly installed on the air inlet pipe 39, and an aeration pipe 311 is fixedly installed on the diversion pipe 310. An installation plate 312 is fixedly installed on the housing 1. A heating device 313 is fixedly installed on the mounting plate 312. The detection module 34 includes a pH meter 341, a dissolved oxygen meter 342, a thermometer 343, and a detection rod 344. The pH meter 341, dissolved oxygen meter 342, and thermometer 343 are fixedly installed on the mounting bracket 33. The detection rod 344 is fixedly installed at the detection end of the pH meter 341, dissolved oxygen meter 342, and thermometer 343. Multiple sets of the detection rod 344, bracket 36, limiting cylinder 38, mounting plate 312, aeration pipe 311, and heating device 313 are provided. Multiple sets of aeration pipe 311 are placed above the bottom filter plate 37. Valves are provided on the water outlet pipe 31 and the water inlet pipe 32. An air inlet valve is provided on the air inlet pipe 39. The water outlet pipe 31 is located below the bottom filter plate 37.

[0025] In this embodiment, before resuscitation, the valve of the inlet pipe 32 is opened to introduce sewage from the wastewater treatment system. After the sewage flows through the inclined plate 35 and is guided by the inclined plate 35, the bottom filter plate 37 carries the activated sludge, forming a sludge environment consistent with the actual system. The valve of the inlet pipe 32 is then closed, and the detection module 34 is activated. The pH meter 341, dissolved oxygen meter 342, and thermometer 343 monitor the core parameters such as pH value, dissolved oxygen content, and temperature in the tank 1 in real time through the detection rod 344, and provide feedback data. Based on the detection data, the operating conditions are adjusted: the water temperature is controlled by heating through multiple sets of heating devices 313 on the mounting plate 312. The temperature is maintained at 35℃ or the same as that of the aeration tank. The air inlet valve of the air inlet pipe 39 is opened, and the gas is distributed to multiple sets of aeration pipes 311 through the diversion pipe 310 to aerate the water evenly. The aeration volume is adjusted by adjusting the opening of the air inlet valve. Combined with the real-time display of the dissolved oxygen meter 342, the dissolved oxygen content is quickly adjusted to a sufficient state required for the recovery of nitrifying bacteria. If the pH value or nutrients are insufficient, the corresponding agents can be added through the water inlet pipe 32. The limiting cylinder 38 fixes the position of the air inlet pipe 39 to ensure the stability of aeration. The valve of the water outlet pipe 31 can control the replacement or discharge of water to maintain the stability of the environment inside the tank 1.

[0026] In one embodiment of the present invention, an auxiliary component 4 is provided on the housing 1. The auxiliary component 4 includes a circular groove 41, which is formed on the housing 1. A cylinder 42 is fixedly installed on the housing 1. A power motor 43 is fixedly installed on the cylinder 42. A short rod 44 is fixedly installed at the output end of the power motor 43. A propeller 45 is fixedly installed on the short rod 44. A sealing tube 46 is fixedly installed inside the cylinder 42. An inclined cylinder 47 is fixedly installed inside the cylinder 42. A circular filter plate is fixedly installed on the housing 1. 48. A triangular guide plate 49 is fixedly installed on the mounting plate 312. Multiple sets of circular groove 41, cylindrical cylinder 42, power motor 43, short rod 44, propeller 45, sealing tube 46, inclined cylinder 47, circular filter plate 48 and triangular guide plate 49 are arranged. The short rod 44 is set inside the sealing tube 46. The short rod 44, propeller 45 and sealing tube 46 are set inside the inclined cylinder 47. The circular filter plate 48 is set inside the circular groove 41. The propeller 45 is directly opposite the circular filter plate 48 and triangular guide plate 49.

[0027] In this embodiment, while the simulation component 3 adjusts its operating conditions, the power motor 43 on the cylinder 42 is started, driving the short rod 44 to rotate the propeller 45. The rotation of the propeller 45 generates thrust, which filters impurities in the water through the circular filter plate 48 in the circular groove 41, forming a directional water flow. This prevents impurities from entangled in the propeller 45 and affecting its operation. The water flow is pushed and guided by the propeller 45, and with the help of the triangular guide plate 49 on the mounting plate 312, the water flow is evenly diffused to various areas of the tank 1, preventing local oxygen deficiency, uneven temperature, or parameter imbalance. The sealing pipe 46 ensures the stable operation of the short rod 44 and the propeller 45, and isolates the impact of water flow on the motor.

[0028] In one embodiment of the present invention, a stirring assembly 5 is provided on the housing 1. The stirring assembly 5 includes a long plate 51, which is fixedly installed on the housing 1.

The round plate 57 is vertically installed on the round rod 56 and is located directly below the conical plate 54.

[0029] In this embodiment, the servo motor 52 on the long plate 51 is started, driving the straight rod 53 to drive the conical plate 54, the baffle plate 55 and the circular plate 57 to rotate synchronously. During the rotation, the multiple sets of baffle plates 55 break the laminar flow state of the water and form strong turbulence, which promotes full contact between nitrifying bacteria and activated sludge and nutrients in the water, and accelerates the recovery process. The conical plate 54 guides the water flow downward, and together with the circular plate 57 on the circular rod 56, it rotates and stirs at the bottom of the tank 1, which effectively prevents activated sludge and nitrifying bacteria from settling at the bottom of the tank 1, avoiding insufficient contact or loss due to sedimentation.
