Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of wastewater treatment devices, specifically a sludge reduction wastewater treatment device. Background Technology
[0002] From a cleaner production perspective, reducing the volume of excess sludge within the system using minimal energy consumption is the most effective way to address the issue. Excess sludge, a type of active substance composed of suspended, colloidal, or dissolved organic matter in wastewater, is largely composed of microbial cells and can therefore be decomposed by microorganisms. This sludge reduction wastewater treatment device employs a facultative anaerobic reactor with a special reflux resistance structure to create turbulent flow, significantly increasing the sludge retention time and ensuring thorough mixing between the sludge and water, thus increasing the contact ratio. In a micro-aerobic or anoxic environment, short-generation, highly adaptable hydrolytic acid-producing bacteria disrupt the bacterial cell structure in the excess sludge, further decomposing it and ultimately converting it into inorganic substances such as CO2, H2O, and NH3. This achieves sludge reduction and discharge, while simultaneously providing nitrogen and carbon sources for other excess sludge, enhancing wastewater treatment capacity.
[0003] Commonly used facultative anaerobic reactors mainly create a micro-aerobic or anoxic environment by forming convection through different influent directions within the reactor to treat pollutants in wastewater. However, they have a limited effect on reducing the volume of residual sludge. Furthermore, due to the simple structure of the reactor and the short water retention time, the hydrolysis and acidification capacity of microorganisms cannot be fully released, thus failing to meet the purpose of sludge reduction. Ultimately, they only provide good support for wastewater treatment and do not fully realize their important role in sludge reduction.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a sludge reduction wastewater treatment device in order to achieve a more practical value. Utility Model Content
[0005] The purpose of this invention is to provide a sludge reduction and wastewater treatment device to solve the problems mentioned in the background art.
[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:
[0007] A sludge reduction wastewater treatment device includes a reactor cylinder. A first connecting ring is installed at the bottom outer side of the reactor cylinder, and a second connecting ring is installed at the top outer side of the reactor cylinder. A first sealing plate is installed at the bottom of the first connecting ring, and a second sealing plate is installed at the top of the second connecting ring. A safety valve is installed at the top of the second sealing plate. A first water inlet pipe is installed at the bottom of the first sealing plate. A second water inlet pipe is installed at the bottom side of one side of the reactor cylinder, and a water outlet pipe is installed at the top side of one side of the reactor cylinder. A pair of probe ports are installed in the middle outer side of the reactor cylinder. A sludge-water mixing chamber is provided at the bottom inner side of the reactor cylinder, and several flow guiding mechanisms are installed inside the sludge-water mixing chamber.
[0008] Furthermore, the flow guiding mechanism includes a flow guiding bucket, and four fixing rods are installed on the outer side of the flow guiding bucket. One end of each fixing rod is engaged with a buckle, and one end of the buckle is fixedly connected to the inner side of the reactor cylinder.
[0009] The beneficial effects of adopting the above-mentioned further solution are that, through the setting of the guide bucket, fixing rod, buckle, and reactor cylinder, the guide bucket can change the flow direction and speed of wastewater in the reactor cylinder, so that the wastewater forms a reasonable flow field in the cavity, avoids dead flow corners, allows sludge and water to contact and react more fully, and improves the sludge reduction effect. The connection method of the fixing rod and buckle facilitates the installation, disassembly and maintenance of the guide bucket, and is convenient for operation when the equipment is repaired or parts are replaced.
[0010] Furthermore, the four fixed rods are distributed at equal intervals.
[0011] The beneficial effect of adopting the above-mentioned further solution is that by distributing the four fixed rods at equal intervals, the guide bucket can be subjected to uniform force and be stably installed in the reactor cylinder, avoiding tilting or displacement of the guide bucket due to uneven force, thereby ensuring that the guide bucket is always in the optimal working position.
[0012] Furthermore, the guide bucket is conical in shape, and the top diameter of the guide bucket is larger than the bottom diameter.
[0013] The beneficial effects of adopting the above-mentioned further scheme are that by making the top diameter of the guide hopper larger than the bottom diameter, the internal turbulence effect is effectively enhanced, guiding the water flow to form a complex flow path, thereby extending the residence time of sewage in the reactor and ensuring a more complete biological reaction process. At the same time, the enhanced turbulence not only improves the mass transfer efficiency, allowing microorganisms to have more complete contact with organic matter in the sewage, but also strengthens the facultative anaerobic environment in the reactor. Under this environment, the microbial community can carry out metabolic activities more effectively, engaging in both aerobic and anaerobic respiration, thereby improving the overall sewage treatment efficiency. The optimization of facultative anaerobic conditions enables specific microbial populations to decompose organic matter more effectively, promoting the sludge reduction process and reducing sludge production. This not only significantly improves the efficiency and quality of sewage treatment, but also effectively reduces the cost of sewage treatment by reducing the discharge of excess sludge.
[0014] Furthermore, flanges are welded to the outer side of one end of the first water inlet pipe, the outer side of one end of the second water inlet pipe, and the outer side of one end of the water outlet pipe.
[0015] The beneficial effect of adopting the above-mentioned further solution is that flanges are welded to the outer side of one end of the first water inlet pipe, the outer side of one end of the second water inlet pipe, and the outer side of one end of the water outlet pipe, facilitating the connection to external pipelines. Furthermore, the reactor cylinder is made of stainless steel.
[0016] The beneficial effect of adopting the above-mentioned further solution is that by using stainless steel for the reactor shell, it has good corrosion resistance, can resist the erosion of various acidic and alkaline substances and corrosive components in the wastewater, extends the service life of the reactor shell, and reduces the frequency of equipment replacement due to corrosion damage.
[0017] Furthermore, a plug is installed at one end of the probe socket.
[0018] The beneficial effect of adopting the above-mentioned further solution is that by installing a plug at one end of the probe port, the probe port can be sealed, preventing wastewater leakage and external impurities from entering the reactor cylinder, thus ensuring the sealing and normal operation of the device.
[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This sludge reduction wastewater treatment device provides space for wastewater treatment through the reactor cylinder arrangement. The first and second connecting rings are used to connect the first and second sealing plates respectively, ensuring the reactor cylinder is sealed and preventing wastewater leakage. The first and second inlet pipes facilitate the entry of wastewater from different sources or treatment stages into the device, achieving multi-channel water inlet. The outlet pipe is used to discharge treated clean water. The safety valve can automatically release pressure when the internal pressure of the device is too high, ensuring safe operation of the device. The probe socket facilitates the installation of detection probes, such as ORP probes and DO probes, to monitor water quality parameters in real time during the treatment process. The sludge-water mixing chamber provides a place for sludge-water mixing reaction, and the flow guiding mechanism helps optimize the flow of wastewater. The flow path within the chamber promotes thorough mixing and reaction of sludge and water, improving sludge reduction and wastewater treatment efficiency. Through the arrangement of the guide bucket, fixing rods, clips, and reactor cylinder, the guide bucket can alter the flow direction and velocity of wastewater within the reactor cylinder, creating a reasonable flow field and avoiding dead zones. This allows for more thorough contact and reaction between sludge and water, enhancing sludge reduction. The connection method of the fixing rods and clips facilitates the installation, disassembly, and maintenance of the guide bucket, making it convenient for equipment repair or component replacement. The evenly spaced distribution of the four fixing rods ensures uniform force on the guide bucket, securing it firmly within the reactor cylinder and preventing tilting or displacement due to uneven force. This ensures the guide bucket is always in the optimal working position. The top of the guide bucket... The larger diameter at the bottom effectively enhances the internal turbulence effect, guiding the water flow into a complex flow path. This prolongs the residence time of wastewater in the reactor, ensuring a more complete biological reaction process. Simultaneously, the enhanced turbulence not only improves mass transfer efficiency, allowing for more thorough contact between microorganisms and organic matter in the wastewater, but also strengthens the facultative anaerobic environment within the reactor. Under this environment, the microbial community can more effectively carry out metabolic activities, engaging in both aerobic and anaerobic respiration, thereby improving overall wastewater treatment efficiency. The optimization of facultative anaerobic conditions enables specific microbial populations to more effectively decompose organic matter, promoting sludge reduction and decreasing sludge production. This not only significantly improves the efficiency and quality of wastewater treatment, but also... Reducing the discharge of residual sludge effectively lowers wastewater treatment costs. Flanges are welded to the outer sides of one end of the first inlet pipe, one end of the second inlet pipe, and one end of the outlet pipe for easy connection to external pipelines. The reactor shell is made of stainless steel, providing excellent corrosion resistance and protecting it from various acids, alkalis, and corrosive components in the wastewater, extending its service life and reducing the frequency of equipment replacement due to corrosion damage. A plug is installed at one end of the probe port to seal it, preventing wastewater leakage and the entry of external impurities into the reactor shell, ensuring the device's sealing and normal operation. This invention effectively increases the hydraulic residence time inside the reactor and enhances the internal turbulence effect.It greatly promotes the homogeneity of fluid mixing and has high practical value.

Under this environment, the microbial community can more effectively carry out metabolic activities. The reactor incorporates both aerobic and anaerobic respiration, thereby improving overall wastewater treatment efficiency.
