Description

Technical Field

[0001] This utility model belongs to the field of biological treatment technology, specifically relating to a layered sulfur autotrophic filter material bioactive reaction device. Background Technology

[0002] Sulfur autotrophic biological treatment technology has become one of the core technologies for denitrification of low C / N wastewater (such as municipal tailwater and industrial wastewater) and purification of sulfide-polluted water bodies due to its advantages of "no need for external carbon source, low operating cost and low sludge production". Its core relies on the efficient metabolic reaction between sulfur autotrophic bacteria (such as sulfur oxidizing bacteria and denitrifying sulfur bacteria) and substrates (sulfides, nitrates, etc.).

[0003] Traditional reaction equipment often adopts a static or single-stirring design: In static reaction, the sulfur autotrophic filter media and the reaction liquid are prone to stratification, and the bacteria and substrate do not have sufficient contact, resulting in a sulfide oxidation rate of less than 60% and a reaction cycle of 24-48 hours; Although a single stirring paddle can improve the mixing degree, the shear force of the paddle blades can easily destroy the biofilm structure of sulfur autotrophic bacteria, resulting in a decrease in bacterial activity of more than 30%, further reducing the reaction efficiency.

Detailed Implementation

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0018] Example Reference Figure 1-4 This is an embodiment of the present invention, which provides a layered sulfur autotrophic filter material bioactive reaction device, comprising: The support assembly 100 includes a base 101, a column 102 fixedly connected to the side wall of the base 101, a top plate 103 fixedly connected to the end of the column 102, and a docking platform 104 fixedly connected to the side wall of the base 101, with the end of the docking platform 104 snapped into the side wall of the column 102. The reaction assembly 200 includes a main turntable 201 rotatably mounted on the middle side wall of the column 102, a reaction flask 202 inserted into the center through hole of the main turntable 201, a secondary turntable 203 rotatably mounted on the upper side wall of the column 102, and a guide pipe 204 sealed on the side wall of the secondary turntable 203. The guide pipe 204 is rotatably mounted above the reaction flask 202, and the bottom outlet of the guide pipe 204 is connected to the end inlet of the reaction flask 202.

[0019] The base 101 serves as the mounting carrier for the columns and supports, ensuring the overall stability of the device. The columns 102 are vertically fixed to the four corner side walls of the base 101, and their ends are rigidly connected to the top plate 103 by bolts, forming a frame structure. This provides vertical support for the reaction assembly 200 and ensures the coaxiality of the upper and lower components, preventing offset during rotation. The top plate 103 is a horizontal metal plate with a feed hole in the center (connected to the end of the feed pipe 204), facilitating the centralized addition of reaction raw materials (such as sulfur autotrophic filter media, reaction liquid, and nutrient solution) without having to add materials to the reaction flasks one by one, thus improving operational convenience. The vertical section of the connecting platform 104 is snapped into the side wall of the column 102 and reinforced with bolts to enhance the column's anti-overturning ability and prevent the column from shaking due to centrifugal force generated when the reaction assembly 200 rotates. It also facilitates the storage of materials to be used. The main turntable 201 has a central through hole evenly distributed around its circumference for inserting the reaction bottle 202 to accommodate the sulfur autotrophic filter material and reaction liquid. During rotation, the materials in the reaction bottle 202 are fully mixed, improving the uniformity of the reaction. The feed pipe 204 is a hollow metal tube, sealed and installed on the side wall of the auxiliary turntable 203. Its upper end is connected to the feed through hole of the top plate 103 (the raw material is added from the top plate through hole and enters the feed pipe), and its lower end extends to the top of the corresponding reaction bottle 202. This enables simultaneous or independent feeding of multiple reaction bottles to meet the raw material requirements of different reaction stages.

[0020] Specifically, a hopper 205 is installed at the bottom of the feed pipe 204, and the bottom outlet of the hopper 205 extends above the feed inlet of the reaction flask 202. A solenoid valve for use with the reaction flask 202 is installed at the bottom of the hopper 205.

[0021] The bottom of the feed pipe 204 is equipped with a hopper 205 (funnel-shaped structure to expand the feed coverage area). The bottom outlet of the hopper is directly opposite the feed inlet of the reaction flask 202 and is equipped with a solenoid valve. The solenoid valve can precisely control the feeding timing and feed amount (the switching frequency and duration can be adjusted by an external controller) to avoid raw material overflow or uneven feeding. At the same time, it can realize synchronous feeding or independent feeding of multiple reaction flasks to meet the raw material requirements of different reaction stages.

[0022] Furthermore, the side wall of the column 102 is bolted to a main support column 206, and a main roller 207 is rotatably mounted at the end of the main support column 206. The side wall of the main roller 207 is in rotatable contact with the side wall of the main turntable 201.

[0023] Among them, the main roller 207 is installed on the side wall of the column 102 through the main support column 206. The main roller makes rolling contact with the side wall of the main turntable 201. The main roller 207 is used to support and share the weight of the main turntable 201, reduce rotational resistance, and ensure that the main turntable 201 rotates smoothly without jamming.

[0024] Furthermore, a support base 208 is bolted to the center of the base 101, and a main motor 209 is fixedly connected to the output shaft end of the support base 208. The output shaft end of the main motor 209 is connected to the central shaft of the main turntable 201 via a coupling.

[0025] The output shaft of the main motor 209 is connected by a coupling. When the main motor 209 starts, it drives the main turntable 201 to rotate at a constant speed. The speed is adjustable to meet different reaction rate requirements.

[0026] Preferably, the side wall of the column 102 is bolted to a secondary support column 210, and a secondary roller 211 is rotatably mounted on the output shaft end of the secondary support column 210. The side wall of the secondary roller 211 is in rotatable contact with the lower side wall of the secondary turntable 203. A secondary motor 212 is bolted to the center of the top plate 103, and the output shaft end of the secondary motor 212 is connected to the central shaft of the secondary turntable 203 via a coupling.

[0027] The auxiliary roller 211 is installed on the auxiliary support column 210, and the auxiliary roller makes rolling contact with the lower side wall of the auxiliary turntable 203. The auxiliary roller is rotatably installed on the upper side wall of the column 102 (directly above the main turntable) through the bearing. The output shaft of the auxiliary motor 212 at the center of the top plate 103 is connected to the auxiliary motor 212 at the center of the top plate 103 through a coupling. The auxiliary motor drives the auxiliary turntable to rotate independently. The guide pipes 204 are evenly installed around the turntable to achieve precise distribution of raw materials.

[0028] Preferably, a feed through hole is provided in the center of the top plate 103, and the feed through hole on the side wall of the top plate 103 is used in conjunction with the end through hole of the guide pipe 204.

[0029] The top plate 103 is a horizontal metal plate with a feed hole in the center (connected to the end of the feed pipe 204), which facilitates the centralized addition of reaction raw materials (such as sulfur autotrophic filter media, reaction liquid, and nutrient solution) without having to add materials to the reaction flask one by one, thus improving the ease of operation.

[0030] During use, the base 101 is fixed to the mounting foundation, forming a stable bottom support; the column 102 connects the base and the top plate, evenly transferring the weight of the reaction components (main turntable, reaction flask, auxiliary turntable, feed pipe, etc.) to the base, avoiding localized deformation due to stress; the symmetrical layout and bolt fastening of the column 102 ensure that the mounting axes of the main turntable 201 and the auxiliary turntable 203 are coaxial, providing a precise reference for their synchronous rotation or independent adjustment; the feed through hole in the center of the top plate is precisely aligned with the feed pipe, ensuring a smooth path for raw material addition; the triangular reinforcement structure of the connecting platform 104 counteracts the lateral force during the rotation of the reaction components, preventing the column from tilting or the base from shifting, ensuring that the entire device remains stable during the reaction, providing a stable environment for the biological reaction (avoiding the impact of vibration on the activity of sulfur autotrophic bacteria). According to the reaction requirements, the main motor 209 and the auxiliary motor 212 are started. Their speeds can be adjusted independently or they can operate synchronously. The main motor drives the main turntable 201 to rotate, causing the reaction bottle 202 to move in a circular motion, ensuring full contact between the sulfur-autotrophic filter media inside the bottle and the reaction liquid, thus increasing the bioreaction rate. The auxiliary motor drives the auxiliary turntable 203 to rotate, ensuring that the feed pipe 204 corresponds one-to-one with the reaction bottle, preparing for feeding. The main and auxiliary rollers rotate synchronously, ensuring smooth and unbiased rotation of the turntables. Reaction raw materials (such as nutrient solution or wastewater to be treated) are added through the feed port on the top plate 103, flowing into the hopper 205 along the feed pipe 204. An external controller triggers the solenoid valve to open, and the raw materials are injected into the corresponding reaction flask 202 according to the preset dosage. After feeding is completed, the solenoid valve closes to avoid leakage or cross-contamination. If staged feeding is required, the solenoid valve can be set to open and close at a time to adapt to the metabolic cycle of sulfur autotrophic bacteria. The main turntable 201 rotates continuously to ensure that the materials in the reaction flask 202 are mixed evenly. The auxiliary turntable 203 can adjust its speed according to feeding requirements (such as being synchronized with the main turntable during feeding and standing by at low speed when not feeding). The layered layout allows feeding and reaction to proceed independently yet in coordination, which avoids interference with the reaction environment during feeding and enables the synchronous operation of multiple reaction flasks, thereby improving reaction efficiency.

[0031] In summary, the main turntable 201 drives the reaction flask 202 to rotate, creating a dynamic suspension mixture between the sulfur autotrophic filter media and the reaction liquid. This increases the contact area between the bacteria and the substrate, shortening the reaction cycle. Furthermore, the absence of rigid agitator shear forces maintains the integrity of the sulfur autotrophic bacteria biofilm, ensuring stable bacterial activity and further guaranteeing reaction efficiency. The auxiliary turntable 203, used in conjunction with the feed pipe 204 and the reaction flask, along with an added solenoid valve for the hopper 205, enables timed, quantitative, and synchronous feeding of raw materials. A staged feeding mode (e.g., low dose in the initial stage, high dose in the middle stage) can be set via an external controller to precisely match the metabolic cycle of the sulfur autotrophic bacteria. The layered layout of the upper feeding layer (auxiliary turntable) and the lower reaction layer (main turntable) completely avoids interference from material splashing and liquid surface fluctuations during feeding. The dual-motor independent drive design allows adjustment of the main / auxiliary turntable speeds according to reaction requirements (e.g., synchronous rotation during feeding, low-speed standby of the auxiliary turntable when not feeding), ensuring that the feeding and reaction rates match the microenvironment of the sulfur autotrophic bacteria and improving reaction stability. The main and auxiliary motors can be set to speed independently to adapt to the reaction requirements of different sulfur autotrophic bacteria genera (such as rapid mixing to adapt to highly active bacteria, and low-speed mixing to adapt to stress-resistant bacteria).
