Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, specifically to a portable coagulation sedimentation algae removal device. Background Technology

[0002] Coagulation and sedimentation is a commonly used physicochemical treatment process in the field of water treatment. Its core process involves adding coagulant to the raw water, forming flocs through rapid stirring, and then slowly stirring to make them grow and settle, thereby removing suspended solids and some colloidal pollutants from the water.

[0003] Currently, coagulation sedimentation technology is mainly used in municipal water supply, sewage treatment, and some industrial water treatment projects. Its core structural form is usually a large sedimentation tank (such as a horizontal flow sedimentation tank, a vertical flow sedimentation tank, or an inclined tube (plate) sedimentation tank). Traditional coagulation sedimentation tanks require a certain hydraulic retention time (generally 15-30 minutes or more) and a large tank volume to meet sedimentation efficiency requirements. This results in a large footprint for the overall equipment or structure, making it difficult to adapt to situations with high space requirements (such as rural water improvement, small-scale emergency water treatment, and mobile water purification systems). Most sedimentation tanks use concrete structures, requiring civil construction, which is time-consuming and not conducive to rapid deployment and flexible adjustment to usage scenarios. Although some equipment manufacturers have attempted to modularize and integrate coagulation sedimentation systems, most of the equipment currently on the market is a simplified device with reduced volume but weakened functionality, making it difficult to balance treatment capacity and sedimentation efficiency. At the same time, although traditional coagulation has a high treatment efficiency for particulate matter, particulate matter does not exist alone but generally coexists with dissolved organic matter, and the coagulation sedimentation method has a very low efficiency in removing dissolved organic matter. Algal blooms are often accompanied by outbreaks of algal toxins, and how to efficiently remove algal cells while simultaneously removing algal toxins has always been a challenge. The shortcomings of existing technologies are: 1. Traditional coagulation methods for algae removal rely solely on the addition of coagulants to disrupt the stability of colloidal particles in the water, reducing electrostatic repulsion between particles or colloids. This leads to the agglomeration of particulate matter and organic matter into clumps through collision, adhesion, bridging, and trapping. However, this method typically produces small flocs with poor settling properties, requiring large sedimentation tanks or, even with limited space, lengthy settling times to effectively remove algae particles.

[0004] 2. Traditional coagulation and sedimentation methods are very effective in removing algal cell particles; however, organic matter such as algal toxins produced by algae cannot be completely removed by traditional coagulation processes. Summary of the Invention

[0005] This utility model addresses the above-mentioned problems by providing a portable coagulation sedimentation algae removal device. Its purpose is to reduce the floor space occupied by the sedimentation tank, to equip the coagulation sedimentation process with equipment, to improve sedimentation treatment efficiency, and to remove algal cells and algal toxins, thereby saving treatment costs.

It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. After reading the present invention, any modifications of the present invention in various equivalent forms by those skilled in the art will fall within the scope defined by the appended claims.

[0021] like Figure 1 As shown, the portable coagulation sedimentation algae removal device includes a reaction tank 1, a sedimentation tank 2, a fiber-algae separation chamber 3, and a fiber return pipe 4, wherein: One side of the reaction tank 1 is connected to the inlet pipe 5, and the other side is connected to the sedimentation tank 2 through the first connecting pipe 6; the side wall of the sedimentation tank 2 is provided with a drain pipe 7 for discharging the supernatant; the bottom of the sedimentation tank 2 is connected to the fiber-algae separation chamber 3; the bottom of the fiber-algae separation chamber 3 is provided with a sludge discharge pipe 8; the side wall of the fiber-algae separation chamber 3 is connected to the reaction tank 1 through a fiber return pipe 4.

[0022] It should be noted that modified plant fibers and Fe were added to reaction tank 1. 3+ Modified plant fibers and Fe 3+ Used to coagulate algae-containing water entering reaction tank 1 and remove some algal toxins.

[0023] It should be noted that the bottom of the sedimentation tank 2 is equipped with a conical sludge hopper 10 for collecting and discharging fibrous algae sediment.

[0024] It should be noted that the fiber-algae separation chamber 3 is equipped with a propeller blade 12; a first valve 11 is provided at the connection between the sedimentation tank 2 and the fiber-algae separation chamber 3; the first valve 11 is controlled to open and close in order to cooperate with the propeller blade 12 to suck the fiber-algae sediment at the bottom of the sedimentation tank 2 into the fiber-algae separation chamber 3.

[0025] It should be noted that a second valve 13 is provided at the connection between the fiber-algae separation chamber 3 and the fiber return pipe 4; the second valve 13 is used to control the opening and closing of the mixture containing fiber and water after separation in the fiber-algae separation chamber 3.

[0026] It should be noted that a screen 14 is provided at the connection between the fiber-algae separation chamber 3 and the sludge discharge pipe 8 to filter the fibers separated by the fiber-algae separation chamber 3 and discharge the algae cells.

[0027] In this specific embodiment, the aperture of the sieve 14 is 500 μm.

[0028] It should be noted that a water supply pipe 15 for replenishing clean water is provided between the fiber return pipe 4 and the fiber-algae separation chamber 3; one end of the water supply pipe 15 is connected to the side wall of the fiber return pipe 4, and the other end is connected to the side wall above the propeller blade 12 of the fiber-algae separation chamber 3.

[0029] It should be noted that a fiber replenishment pipe 16 for replenishing fibers is connected to the side wall of the connecting pipe between the fiber return pipe 4 and the reaction tank 1.

[0030] It should be noted that the working principle of this utility model specifically includes the following steps: S100. After the algae-containing water enters reaction tank 1, it reacts with modified plant fibers and Fe. 3+ Stir and mix to ensure the algae-containing water coagulates fully.

[0031] S200. After the algae-containing water is fully coagulated, the coagulated algae-containing water is controlled to enter the sedimentation tank 2; the fiber-algae sediment in the sedimentation tank 2 is collected at the bottom of the conical sewage hopper 10 through sedimentation, and the supernatant flows out through the drain pipe 7.

[0032] S300. Control the second valve 13 to close and the first valve 11 to open according to the preset time interval, and at the same time start the propeller blade 12 to rotate at high speed to suck; when the amount of fiber-algae flocs sucked in the fiber-algae separation chamber 3 reaches the preset suction amount threshold, close the first valve 11.

[0033] After the fibers in the fiber-algae separation chamber 3 are cleaned, the second valve 13 uses clean water through the water supply pipe 15 to recover the fibers, and then the next stage of algae-containing water treatment begins.

[0034] It should be further explained that during the high-speed rotation of the propeller blades 12, the fibers separate from the adhering algal cells, while the water flows rapidly downwards. This allows the separated algal cells to flow out quickly, while the downward-flowing fibers are trapped by the screen 14. This process cleans the fibers and separates them from the algae.
