Description

Technical Field

[0001] This application belongs to the field of wastewater treatment technology, specifically a device for efficient aeration oxidation of wastewater. Background Technology

[0002] With the rapid development of human society and modern industry, a large amount of sulfides generated during daily water use enters wastewater. For example, incineration power generation and washing jeans in the clothing industry can lead to high COD levels in wastewater. However, if this wastewater is not treated, it will inevitably cause irreversible damage to subsequent treatment processes and equipment lifespan.

[0003] For example, CN220788234U discloses a high-efficiency aeration oxidation device for wastewater treatment, including an aeration oxidation tank. Air is blown into the chambers via an inlet pipe and nozzles using a Roots blower for aeration. When the wastewater level in the first chamber is full, the wastewater enters the second chamber for aeration, and so on. Wastewater in each chamber is aerated sequentially while flowing. Simultaneously, waste gas in the wastewater is discharged through the waste gas outlet for further treatment, improving the aeration efficiency and treatment effect. The wastewater in the aeration oxidation tank can be collected again through a wastewater return port for recirculation aeration. An overflow port prevents excessively high wastewater levels or excessively high pressure within the tank. In this embodiment, both the wastewater return port and the overflow port are equipped with covers for opening, allowing them to be opened when needed.

[0004] However, the high-efficiency aeration oxidation device in this application has the problem of insufficient wastewater residue treatment. Wastewater remains inside the machine and there is no filter interception device, which can easily cause blockage of the aeration chamber and affect the aeration efficiency. Utility Model Content

[0005] The purpose of this application is to provide a device for efficient aeration oxidation of wastewater, in order to solve the problems mentioned above, such as insufficient wastewater treatment, wastewater remaining in the machine, lack of filtration and interception devices, which easily leads to blockage of the aeration chamber and affects aeration efficiency.

[0006] The technical solution adopted in this application is as follows:

[0007] A device for efficient aeration oxidation of wastewater includes an aeration oxidation device body, an overflow pipe fixedly installed on the back of the aeration oxidation device body, a water collection tank fixedly connected to the bottom of the overflow pipe, a water valve slidably installed on the front of the water collection tank, a water inlet fixedly connected to the bottom of the water collection tank, a filter port provided on the side of the water inlet, and a filter plate embedded inside the filter port.

[0008] By adopting the above technical solution, an overflow port is fixedly installed at the top of the last aeration chamber of the device, extending to the outside of the device and further connecting to the top of the collection tank. Through the installation of fixed pipes, overflow wastewater can be automatically collected and a secondary reuse system can be formed, thereby reducing manual processing time and improving efficiency. A valve is installed at the top of the collection tank to control the flow of wastewater into the inlet; the inlet is designed with a grooved filter layer mounting position, housing a removable filter plate to intercept fibers and large suspended solids, preventing clogging of the aeration chamber. This filter plate adopts a convenient installation structure, further shortening replacement and maintenance time.

[0009] In a preferred embodiment, an aeration chamber is fixedly installed inside the aeration oxidation device body, and an aeration chamber bottom shell is installed at the bottom of the aeration chamber.

[0010] By adopting the above technical solution, four aeration chambers are fixedly installed inside the device. The bottoms of each chamber are connected by pipes, and wastewater is diverted to the other three aeration chambers through the pipes to reduce the working pressure. The bottom of aeration chamber No. 1 is specially designed: a downward-sloping ramp is added, and a detachable outer shell is installed. The outer shell has a fixing plate inside, which is installed and quickly fixed to the bottom of the chamber by a slight inward deformation. It can work in conjunction with the side cleaning device to efficiently remove sludge from the chamber.

[0011] In a preferred embodiment, a sliding groove is provided on the side of the aeration oxidation device body, a cleaning outer handle is slidably installed inside the sliding groove, a fixing block is fixedly installed at the tail of the cleaning outer handle, and a circular shovel is fixedly installed on the front of the fixing block.

[0012] By adopting the above technical solution, a slide is fixed on the side of the aeration device and extends into the first aeration chamber. A cleaning handle is fixed inside the slide and extends to the outside of the device. The cleaning handle is connected to a fixing block inside the aeration chamber. A round shovel is connected to the top of the fixing block. The sludge accumulated at the bottom of the aeration chamber is cleaned by sliding. The cleaning is completed by removing the outer shell of the aeration chamber at the bottom of the slope.

[0013] In a preferred embodiment, an exhaust port is fixedly installed on the top of the aeration oxidation device body, and a cleaning pipe is wrapped around the exhaust port, with a cleaning port at the top of the cleaning pipe.

[0014] By adopting the above technical solution, an exhaust gas outlet is opened at the top of the device to collect the exhaust gas generated by the four aeration chambers. This design, on the one hand, prevents the chambers from cracking due to excessive internal pressure by relieving pressure; on the other hand, the exhaust gas outlet is connected to a condensation pipe with a condensation module inside, which can condense the vapor containing wastewater components into liquid, which then flows back to the overflow pipe by gravity. In addition, a cleaning port is added to the top of the pipe to facilitate the cleaning of residues inside the pipe when the machine is shut down, thereby extending the service life of the equipment.

[0015] In a preferred embodiment, an oxygen delivery pump is connected to the side of the aeration oxidation device body via a duct, and a Roots blower is fixedly connected to the side of the aeration oxidation device body via a duct.

[0016] By adopting the above technical solution, air is blown into the No. 1 aeration chamber through the air inlet pipe and nozzles by a Roots blower arranged on the side for aeration treatment. Considering the high suspended solids and high color of denim washing wastewater, the nozzles are designed with microporous aerators to prolong the gas-liquid contact time and improve oxygen transfer efficiency. The oxidation delivery pump extends into the No. 1 aeration chamber through the main body of the device to ensure uniform diffusion of the oxidant.

[0017] In a preferred embodiment, a drain outlet is fixedly installed on the side of the aeration oxidation device body.

[0018] By adopting the above technical solution, an outlet is set on the side of the device body. The wastewater in the four aeration chambers is discharged from the system through the outlet after being treated by aeration oxidation.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0020] In this application, an overflow port is fixedly installed at the top of the last aeration chamber of the device, extending to the outside of the device and further connecting to the top of the collection tank. By installing fixed pipes, overflow wastewater can be automatically collected and a secondary reuse system can be formed, thereby reducing manual processing time and improving efficiency. A valve is installed at the top of the collection tank to control the flow of wastewater into the inlet; the inlet is designed with a grooved filter layer mounting position, housing a removable filter plate to intercept fibers and large suspended particles, preventing clogging of the aeration chambers. This filter plate adopts a convenient installation structure, further shortening replacement and maintenance time. Four aeration chambers are fixedly installed inside the device, with the bottoms of each chamber connected by pipes. Wastewater is diverted through these pipes to the other three aeration chambers to reduce operating pressure. The bottom of the first aeration chamber is specially designed: it features a downward-sloping ramp and a removable outer shell. The outer shell contains a fixing plate, which uses a slight inward deformation to achieve a snap-fit ​​installation and quick fixation to the bottom of the chamber, enabling efficient removal of sludge from the chamber in conjunction with a side cleaning device.

[0028] Example:

[0029] An efficient aeration oxidation device for wastewater includes an aeration oxidation device body 1. An overflow pipe 11 is fixedly installed on the back of the aeration oxidation device body 1. A water collection tank 12 is fixedly connected to the bottom of the overflow pipe 11. A water valve 13 is slidably installed on the front of the water collection tank 12. An inlet 14 is fixedly connected to the bottom of the water collection tank 12. A filter port 15 is provided on the side of the inlet 14. A filter plate 16 is embedded inside the filter port 15. An overflow port is fixedly installed at the top of the last aeration chamber of the device, extending to the outside of the device and further connected to the top of the water collection tank. By installing fixed pipes, overflow wastewater can be automatically collected and a secondary reuse system can be formed, thereby reducing manual processing time and improving efficiency. A valve is provided at the top of the water collection tank to control the flow of wastewater into the inlet. The inlet is designed with a grooved filter layer mounting position, with a built-in removable filter plate to intercept fibers and large suspended solids, preventing blockage of the aeration chamber. The filter plate adopts a convenient installation structure, further shortening replacement and maintenance time.

[0030] The aeration oxidation equipment body 1 has an aeration chamber 2 fixedly installed inside. An aeration chamber bottom shell 3 is installed at the bottom of the aeration chamber 2. Four aeration chambers are fixedly installed inside the device, and the bottoms of each chamber are connected by pipes. Wastewater is diverted through these pipes to the other three aeration chambers to reduce operating pressure. The bottom of aeration chamber number one is specially designed: it features a downward-sloping ramp and a detachable shell. The shell has a fixing plate inside, which uses a slight inward deformation to achieve a snap-fit ​​installation and quick fixation to the bottom of the chamber. This, combined with the side cleaning device, efficiently removes sludge from the chamber.

Furthermore, the addition of a cleaning port at the top of the pipe facilitates the cleaning of residues inside the pipe during shutdown, thereby extending the equipment's service life.

The Roots blower, located on the side, blows air through the air inlet pipe and nozzles into the first aeration chamber for aeration treatment. Considering the high suspended solids and high color of denim washing wastewater, the nozzles employ a microporous aerator design to prolong the gas-liquid contact time and improve oxygen transfer efficiency. The oxidation delivery pump extends into the first aeration chamber through the device body to ensure uniform diffusion of the oxidant.

[0034] A drain outlet 20 is fixedly installed on the side of the aeration oxidation equipment body 1. A water outlet is set on the side of the equipment body.
