Technical Field

[0001] This utility model relates to an integrated continuous ion exchange water purification device that couples continuous ion exchange with an integrated "horizontal flow tube sedimentation + ultra-light filter media upward flow" water purification system. It belongs to the field of water treatment technology, and specifically relates to a device that can significantly improve COD removal efficiency. Mn The equipment achieves a high removal rate, saves on the amount of coagulant added in subsequent processes, reduces the floor space required, and avoids the bromate and biological leakage problems of ozone / biological activated carbon processes, thus greatly improving water quality safety. Background Technology

[0002] Drinking water sources such as reservoirs and streams are prone to exceeding standards for humic acid, organic matter, color, turbidity, and bacteria due to seasonal climate changes, posing a threat to human health. Currently, ozone-activated carbon treatment equipment is commonly used in China for deep treatment of this type of water. However, activated carbon filter media gradually loses its adsorption capacity over long-term operation, resulting in unstable water treatment effects and a large footprint. Furthermore, in the ozone-biological activated carbon treatment process, bromide ions in the raw water react with ozone to form bromate, a disinfection byproduct. Bromate is difficult to remove using conventional methods, increasing the carcinogenic risk of drinking water. Additionally, due to the loss of adsorption capacity of activated carbon filter media over time, or the shedding of microorganisms due to water flow impact, microorganisms accumulate on the surface of the activated carbon during water treatment, leading to their excretion with the water and an increase in the number of bacteria and viruses in the effluent, resulting in lower safety of the effluent water.

[0003] Publication No. CN110407419B discloses a Class IV standard surface water wastewater treatment process and equipment, including a pre-anoxic tank, an anaerobic tank, an anoxic tank, an MBBR aerobic tank, an MBR membrane tank, an ECPI electrocatalytic oxidation device, a biochar filter, an NPDP nitrogen and phosphorus deep purifier, and an ecological pond connected in sequence. A nitrification liquid return pipe is connected between the end of the MBBR aerobic tank and the front end of the anoxic tank, and a sludge return pipe is connected between the end of the MBR membrane tank and the pre-anoxic tank. This wastewater treatment process and equipment uses a biological carbon filter for deep treatment of surface water. However, activated carbon filter media gradually loses its adsorption capacity during long-term operation, resulting in unstable water treatment effects and a large footprint. In addition, in the ozone-biological activated carbon treatment process, bromide ions in the raw water react with ozone to generate bromate, a disinfection byproduct. Bromate is difficult to remove by conventional treatment methods, increasing the carcinogenic risk of drinking water. Furthermore, due to the loss of adsorption capacity of activated carbon filter media over long-term operation, or the shedding of microorganisms caused by water flow impact, microorganisms accumulate on the surface of activated carbon during the water treatment process, leading to the outflow of microorganisms with the water and an increase in the number of bacteria and viruses in the effluent, resulting in lower safety of the effluent water quality.

[0004] Publication No. CN221254301U discloses a surface water treatment device suitable for small rural water plants. It employs an integrated water purification technology of "horizontal pipe sedimentation + ultra-light filter media filtration" to purify surface water in mountainous rural water plants. The device includes a treatment tank, the internal space of which is divided sequentially according to the direction of water flow into a coagulation zone, a water distribution zone, a first buffer zone, a sedimentation zone, a second buffer zone, a water collection zone, and a filtration zone. A sludge collection zone is located below the sedimentation zone. The treatment tank includes a horizontal pipe sedimentator, a connecting pipe, an air pump, a water outlet pipe, ultra-light filter media, a waste discharge pipe, a first sludge discharge pipe, a second sludge discharge pipe, a water inlet, a chemical dosing pump, porous balls, a water outlet, an air inlet, a backwash port, and a waste discharge port. One end of the treatment tank has a water inlet connected to the coagulation zone, which contains porous balls. This surface water treatment device performs single-stage treatment of surface water, reducing COD... Mn The removal rate is low, and the effluent can only be used for emergency water supply in rural areas. In addition, in order to maximize the removal rate of COD in the water, a large amount of coagulant is added during the water treatment process, resulting in high operating costs.

[0050] The flocculation zone (14), water distribution zone (15), sedimentation zone (16), sludge collection zone (17), and filtration zone (18) together constitute a water purification tank. The inlet (9) is connected to one end of the water purification tank and is interconnected. The inlet (9) is connected to the outlet of the pipe mixer (10) through a connecting pipe. The water purification tank is arranged in the following order according to the direction of raw water flow: flocculation zone (14), water distribution zone (15), sedimentation zone (16), and filtration zone (18). The sludge collection zone (17) is located below the sedimentation zone (16).

[0056] The water outlet (5) is located at the other end of the water purification tank and is connected to the filtration area (18);

[0057] In use, untreated raw water enters the HRC exchange tank (13) through the ion exchange inlet (1). Through the stirring and agitation of the exchange tank stirring assembly (24) and the exchange tank gas assembly (28), the magnetic ion exchange resin is fully mixed and aggregated to form a suspended reaction layer. A large amount of organic matter in the raw water is removed. During the suspension reaction, some ion exchange resin is captured by the resin trap (2) as it flows with the water. The exchanged magnetic ion exchange resin enters the resin regeneration tank (12) and is regenerated using concentrated brine. The regeneration tank stirring assembly (21) enables the exchange resin and brine to come into full contact. The raw water that has undergone primary treatment enters the pipeline mixer (10) through the ion exchange outlet pipe (11). Meanwhile, the PAC dosing device (3) adds chemicals to the pipeline mixer (10) through the dosing port (4). After the raw water and chemicals are fully mixed in the pipeline mixer (10), they enter the flocculation zone (14) through the inlet (9) and flocculate with the porous flocculants in the flocculation zone (14). Large flocculent particles settle downwards, while small flocculent particles and raw water enter the distribution zone (15) through the distribution flower wall. After buffering and settling, they enter the sedimentation zone (16). The flocculent particles in the raw water settle to the sludge collection zone (17) through the horizontal flow pipe sedimentator. The settled raw water enters the filtration zone (18) and is discharged from the outlet (5) after being filtered by the ultra-light filter media. During the above process, the sludge discharge electric valve (7) extracts the sediment in each sludge discharge pipe (8).

[0058] The exchange tank inclined plate assembly (26) has multiple components. The design of two adjacent exchange tank inclined plate assemblies (26) with opposite inclination directions can divide the formed suspended reaction layer, reduce the direct impact of water flow on the magnetic ion exchange resin in the reaction layer, thereby maintaining the stability of the suspended reaction layer and improving the contact efficiency between organic matter and resin. It is also beneficial for heavier impurities to settle on the inclined plate and slide down the inclined surface to the bottom of the tank, which is convenient for subsequent cleaning and maintenance. Due to the dividing effect of the inclined plate, the flow path of water in the exchange tank is extended, which increases the water residence time and provides a longer reaction time, which is beneficial to improving the organic matter removal rate.

[0059] The mixing unit (19) is designed with intersecting spirals in opposite directions, which makes the flow of raw water more complex and enhances the turbulence effect of raw water, so that raw water and reagent can be fully mixed. At the same time, the intersecting spirals can cause the raw water to change direction and flow rate multiple times when passing through, increasing the contact between raw water and reagent, improving the mixing effect, and enabling short-time mixing of raw water and reagent.

[0060] The design of the cross-sectional diameter of the dosing port (4) being smaller than that of the cross-sectional diameter of the pipe mixer (10) can reduce the risk of drug leakage. The small-diameter dosing port (4) combined with the pipe mixer (10) can quickly and evenly mix the drug after it enters the main pipe, avoiding uneven distribution of the drug in the pipe, and at the same time, it is convenient to flexibly adjust the dosage.

[0061] The design that the length of the flocculation zone (14) is greater than that of the water distribution zone (15) provides more time for particles in the water to collide and aggregate, thereby forming larger flocs. At the same time, it helps to reduce the short-circuit flow of water on the pool wall or bottom, ensuring that all raw water can be fully mixed and reacted.

[0062] This approach significantly improves the removal rate of CODMn, reduces the amount of coagulant required in subsequent processes, minimizes the floor space required, and avoids bromate and biological leakage issues associated with ozone / biological activated carbon processes, thereby greatly enhancing water quality safety.

[0063] It should be noted that, unless otherwise explicitly specified and limited, the terms "placed," "connected," and "linked" should be interpreted broadly. For example, they can refer to fixed connections such as folded edges, rivets, pins, adhesives, and welds; detachable connections such as threaded connections, snap-fit ​​connections, and hinges; integral connections; electrical connections; direct connections; or indirect connections via an intermediate medium; or internal connections between two components. Those skilled in the art can understand the specific meaning of these terms in this utility model based on the specific circumstances.
