Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and in particular relates to a device that facilitates the treatment of recalcitrant organic pollutants in wastewater. Background Technology

[0002] The difficult-to-treat organic pollutants in wastewater often have stable chemical structures. Common types include polycyclic aromatic hydrocarbons, halogenated hydrocarbons, antibiotics, and phenolic derivatives. They mainly originate from industrial emissions such as chemical, pharmaceutical, and dyeing industries, as well as domestic sewage and agricultural residues. These pollutants are difficult to degrade by conventional biological processes and tend to accumulate in water bodies, not only damaging aquatic ecosystems but also potentially entering the human body through the food chain, posing health risks. Treatment requires advanced oxidation, adsorption, and other specialized technologies, which are costly and represent a key challenge in the field of wastewater treatment.

[0003] Traditional methods for treating recalcitrant organic pollutants in wastewater primarily involve multi-stage filtration combined with chemical reactions to achieve purification. However, when wastewater enters the treatment system, it contains not only organic pollutants but also other impurities. These impurities are not fixed in size, and some are quite large. This significantly increases the likelihood of clogging the system during subsequent treatment. Furthermore, organic pollutants require large amounts of chemicals for complete filtration, resulting in high treatment costs.

[0004] In view of this, we propose a device that facilitates the treatment of recalcitrant organic pollutants in wastewater. Utility Model Content

[0005] The purpose of this invention is to provide a device for easily treating recalcitrant organic pollutants in wastewater, thereby solving the problems mentioned in the background art.

[0006] In view of this, the present invention provides a device for easily treating recalcitrant organic pollutants in wastewater, including a treatment cylinder, an inlet pipe installed at the top of the treatment cylinder, and further comprising: A processing basin is fixedly connected to the top of the cavity of a processing cylinder. The top of the processing basin has multiple limiting grooves that are capsule-shaped. A movable screen plate is slidably connected to the bottom of the processing basin. A sliding column is fixedly connected to the top of the movable screen plate. A partition plate is fixedly connected to the top of the sliding column. The partition plate is located at the bottom of the cavity of the processing basin. Each sliding column slides laterally in its corresponding limiting groove. The position of each sliding column is offset from the position of the circular hole at the top of the movable screen plate. A rotating assembly located inside the cavity of the processing cylinder and used to control the sliding of the movable screen plate at the bottom of the processing basin; A material-carrying sieve box, which is movably snapped into the bottom of the cavity of the processing cylinder; A disassembly assembly is located on the outer wall of the processing cylinder and is used to fix the position of the loading screen box.

[0007] In this technical solution, the wastewater to be treated is introduced into the cavity of the treatment cylinder through the feed pipe at the top of the treatment cylinder. The wastewater then directly enters the cavity of the treatment basin and drains down through the round holes on the wall of the movable screen plate. At this time, large impurities in the wastewater will accumulate in the cavity of the treatment basin due to the obstruction of the partition plate. Simultaneously, the motor power is turned on, and the motor drives the drive shaft to rotate. When the drive shaft rotates, it drives the follower plate at its top and the cylinder at the top of the follower plate to rotate synchronously. When the cylinder rotates, it drives the connecting piece to rotate synchronously through the pull rod. When the connecting piece rotates, it drives the movable screen plate to move back and forth laterally at the bottom of the treatment basin. When the movable screen plate moves, it drives the sliding column to move laterally within the limiting groove. The sliding column drives the partition plate to move back and forth within the cavity of the treatment basin. The round holes at the top of the movable screen plate will open and close repeatedly as they align with the limiting groove. When the drive shaft rotates, it also drives the stirring rod to agitate the wastewater in the cavity of the treatment cylinder. As the wastewater drains down from the wall of the movable screen plate... Open the valve of the dosing pipe, then add the purification agent into the dosing pipe cavity. Simultaneously, use the rotating stirring rod to agitate the wastewater to mix and react with the agent. At the same time, the organic adsorbent material loaded in the screen box cavity adsorbs impurities in the wastewater in the treatment cylinder cavity. After one hour, open the drain valve of the drain pipe, and then discharge the pretreated wastewater from the treatment cylinder cavity into the treatment tank for further treatment. The top of the treatment cylinder can be flipped open. When it is necessary to clean the impurities accumulated in the treatment basin cavity, the top of the treatment cylinder can be flipped open to manually clean the cavity. The reciprocating movable screen plate and partition plate on the treatment basin wall can filter large impurities in the wastewater to be treated separately and automatically prevent the round holes on the movable screen plate wall from clogging. The screen box loaded with organic adsorbent at the bottom of the treatment cylinder cavity can achieve preliminary treatment of recalcitrant organic matter in the wastewater, thereby facilitating subsequent wastewater treatment processes and improving subsequent treatment efficiency.

[0008] In the above technical solution, the rotating component further includes: The main shaft is rotatably connected to the bottom of the cavity of the processing cylinder. A follower disk is fixedly connected to the top of the main shaft. The follower disk is disc-shaped. Two identical stirring rods are fixedly connected to the outer wall of the main shaft.

[0009] In this technical solution, the drive shaft can stably drive the stirring rod to stir the sewage in the treatment cylinder and the follower disc and the cylinder on the top of the follower disc to rotate when rotating.

[0010] In the above technical solution, the pull rod is further described as a capsule-shaped rod, and a circular groove is symmetrically opened through the top of the pull rod. The circular groove is adapted to the size of the cylinder at the top of the follower disk. The connecting piece is composed of a circular block in the upper part and a circular disk at the bottom. The circular block of the connecting piece is inserted into the circular groove of the pull rod.

[0011] In this technical solution, the pull rod can synchronously pull the connecting piece to move stably as the top cylinder of the follower plate rotates.

The disassembly block is rectangular and has a sealing ring fitted on its outer wall. Hinges are symmetrically fixed to one side wall of the disassembly block. The disassembly block is rotatably connected to the side wall of the loading screen box via the hinges. The same loading screen box is provided on each hinge side wall.

[0013] In this technical solution, the material-carrying screen box can be rotated 90 degrees upwards with the hinge as the center. By loading organic adsorbent materials into the detachable material-carrying screen box, the sewage can be further purified, achieving low cost and convenient subsequent sewage treatment.

[0014] In the above technical solution, the loading screen box is a hollow rectangular mesh, and the side wall of the loading screen box facing the disassembly block is fixedly connected to a hinge. The bottom of the cavity of the processing cylinder is inclined, and a rectangular slot adapted to the disassembly block is opened on one side wall of the processing cylinder. The symmetrical loading screen boxes and the drive shaft are misaligned. The bottom of each loading screen box is attached to the bottom of the cavity of the processing cylinder. A motor for driving the drive shaft to rotate is fixedly connected to the bottom of the processing cylinder.

[0015] In this technical solution, the rectangular groove on the side wall of the processing cylinder is used to facilitate the disassembly of the material-carrying screen box and the disassembly block when cleaning the cavity of the material-carrying screen box.

Each rectangular plate and rectangular block has a threaded hole on its wall, and a bolt is installed in each threaded hole.

[0017] In this technical solution, the bolts can stably fix the disassembly block and the loading screen box in the cavity of the treatment cylinder, thereby preventing the loading screen box from moving in the cavity of the treatment cylinder and affecting the adsorption of impurities in the sewage by the organic adsorbent material in the loading screen box cavity.

When the wastewater leaks, open the valve of the dosing pipe 15, and then add the purification agent into the cavity of the dosing pipe 15. At the same time, use the rotating stirring rod 11 to stir the wastewater to mix and react with the agent. Simultaneously, the organic adsorbent material loaded in the cavity of the loading screen box 14 adsorbs the impurities in the wastewater in the cavity of the treatment cylinder 1. After one hour, open the drain valve of the drain pipe 16, and then discharge the pretreated wastewater from the cavity of the treatment cylinder 1 into the treatment tank for treatment. The top of the treatment cylinder 1 can be flipped open. When it is necessary to clean the impurities accumulated in the cavity of the treatment basin 2, the top of the treatment cylinder 1 can be flipped open to manually clean the cavity of the treatment basin 2. The movable screen plate 4 and the partition plate 6 that move back and forth on the wall of the treatment basin 2 can filter the large-sized impurities in the wastewater to be treated separately, and automatically prevent the round holes on the wall of the movable screen plate 4 from being blocked.

[0040] Working principle: During use, a liquid inlet pipe is installed at the top of the treatment cylinder 1. The wastewater to be treated is introduced into the cavity of the treatment cylinder 1 through the inlet pipe at the top of the treatment cylinder 1.

At the same time, the rotating stirring rod 11 agitates the sewage to mix and react with the agent. Meanwhile, the organic adsorbent material loaded in the cavity of the loading screen box 14 simultaneously adsorbs impurities in the sewage in the cavity of the treatment cylinder 1. After one hour, the drain valve of the drain pipe 16 is opened, and then the pretreated sewage is discharged from the cavity of the treatment cylinder 1 into the treatment tank for further treatment.
