A highly efficient water purification system equipment

Abstract

The utility model discloses a high-efficiency clarifying water purification system equipment, which includes a dosing mixing area, a dissolved gas release area, a scum separation area, a biochemical reaction area, a mud discharge area, a clear water area and a water outlet area. Raw water enters the dosing mixing area through a water inlet pipe, and enters the dissolved gas release area after mixing with the agent. It is released by reducing pressure, so that the suspended flocs in the water adhere to the microbubbles to form scum. Then it overflows into the scum separation area, and then overflows into the biochemical reaction area. The scum scraping mechanism scrapes the scum to the mud discharge area. The water after scum removal is purified by a biofilm, which increases the biomass and biological species in the aeration tank and improves the sewage treatment efficiency of the aeration tank. The purified water with microorganisms overflows into the clear water area through the overflow pipe at the bottom, and is finally pumped into the river by a pump. The equipment has wide adaptability, rapid startup, and impact resistance. It solves the problems of poor sensory quality caused by high suspended matter in the river, slow effect and complex operation of conventional biochemical treatment processes, and improves the efficiency of sensory improvement in the river.

Description

Technical Field

[0001] The utility model relates to the field of environmental protection, in particular to water treatment equipment. Background Art

[0002] The chromaticity and transparency of river water are the water quality indicators that people can most intuitively feel. By reducing the high chromaticity of water bodies and increasing the transparency of water bodies, the sensory quality of water bodies can be improved. The reasons for the low sensory quality of river water bodies are relatively complex and are closely related to environmental factors and the physical and chemical properties of river water.

[0003] The substances in river water that have a direct impact on sensory quality mainly include phytoplankton and the chlorophyll a it produces, suspended solids and dissolved organic carbon, etc. The matrix in the water absorbs, scatters and blocks light, or has a strong absorption spectrum for a certain band, resulting in a certain color, which will lead to higher chromaticity or lower transparency of the water body, thereby reducing the sensory quality.

[0004] At present, measures to improve the sensory quality of water bodies include physical treatment, biochemical ecological treatment and physicochemical treatment. Physical treatment methods include water diversion and replacement and dredging of sediment, but their disadvantages are large engineering workload and high cost. Biochemical ecological treatment methods include biological treatment methods such as artificial wetlands and biofilters, but this method occupies a large area and has a slow treatment speed. Physicochemical treatment methods include coagulation sedimentation and medicated flotation, which have obvious advantages, but need to be optimized in terms of agent addition and process flow.

[0005] The above process equipment are all suitable for the purification and sensory improvement of river water, but there are also problems such as large engineering workload and cost. At the same time, a single technical equipment is difficult to adapt to the changing changes in river water quality, and new technical equipment needs to be developed to improve it. Utility Model Content

[0006] The technical problem solved by the utility model is that a single technical device for improving the sensory quality of water bodies is difficult to adapt to the changeable changes in river water quality.

[0007] To solve the above technical problems, the utility model provides the following technical solutions: an efficient clarifying water purification system equipment, including a dosing mixing area, a dissolved gas release area, a scum separation area, a biochemical reaction area, a mud discharge area, a clear water area and a water outlet area located in the same equipment.

[0008] The dissolved gas release zone is located beside the dosing mixing zone and is connected to the overflow weir at the upper end of the dosing mixing zone; the scum separation zone is located beside the dissolved gas release zone and is connected to the upper end of the baffle of the dissolved gas release zone; the biochemical reaction zone is located beside the scum separation zone and is connected to the upper end of the baffle of the scum separation zone; a scum scraper is provided on the top of the biochemical reaction zone and the mud discharge zone, and the scum is scraped to the mud discharge zone through the mud scraper mechanism; a clear water zone and a water outlet zone are provided beside the biochemical reaction zone, and an overflow pipe is provided at the bottom of the biochemical reaction zone, and the biochemical reaction zone is connected to the clear water zone through the bottom overflow pipe.

[0009] During normal operation, water intake and aeration are synchronized. The river water passes through the dosing mixing area, dissolved air release area, scum separation area, biochemical reaction area, and mud discharge area in turn. It reacts with the biofilm attached to the filler in an aerobic environment to remove some pollutants such as ammonia nitrogen, and then enters the clean water area through the bottom overflow pipe.

[0010] In the scum separation area, since the lower part of the scum separation area is connected to the lower part of the biochemical reaction area, and the upper part of the scum separation area is connected to the upper part of the biochemical reaction area, the water in the scum separation area enters the biochemical reaction area through the lower part, and the scum floats on the water surface. The scraping mechanism operates to scrape the scum on the water surface into the mud discharge area.

[0011] The dosing and mixing area is equipped with a mixer.

[0012] The scum separation area is provided with a dissolved air releaser, which is connected to the dissolved air tank. The dissolved air releaser is a device used in the pressure dissolved air flotation water purification method. This water purification method introduces a large number of fine bubbles released from the pressure dissolved air water into the water to be treated, and uses the buoyancy of the bubbles adhering to the solid impurities to achieve the purpose of rapid separation of solid and liquid and increase the concentration of scum. The dissolved air releaser is a key device in the pressure dissolved air flotation water purification system. The pressure dissolved air water can only release a large number of fine bubbles after the pressure is reduced and the energy is dissipated through the device.

[0013] The biochemical reaction zone is equipped with an aeration plate and a packing layer above the aeration plate. Water enters the lower part of the biochemical reaction zone from the lower part of the scum separation zone, passes through the aeration layer and the packing layer from bottom to top, and reacts with the biofilm attached to the packing in an aerobic environment to remove some pollutants such as ammonia nitrogen, and then enters the clean water zone through the water collection pipe.

[0014] The biochemical area and the clean water area are equipped with backwash pipelines and clean water return pumps. When the outlet water turbidity value is detected to rise to 10NTU or the set value, the backwash pipeline is opened according to the setting to backwash the packing layer. Before the backwash operation, the system stops water intake and dosing, and resumes normal operation after the backwash is completed.

[0015] A water level regulating gate is provided in the clean water area. The height of the water level regulating gate is adjusted according to the thickness of the scum in the scum separation area. The thicker the scum thickness, the higher the water level regulating gate is adjusted, the higher the water level is, and the greater the amount of sludge scraped.

[0016] This equipment can be modularly deployed on the river bank to achieve local treatment of river water and effective treatment of suspended matter in water. At the same time, the equipment system has the characteristics of wide adaptability, rapid startup, and impact resistance. It solves the problems of poor sensory quality caused by high suspended matter in the river, slow effect and complex operation of conventional biochemical treatment processes, and improves the efficiency of river sensory improvement.

[0035] The water outlet area 7 is provided with a water pump 25 and a water outlet pipe 30 .

[0036] The raw water enters the dosing and mixing area 1 through the water inlet pipe 20, and produces suspended flocs after mixing with the reagent; it flows into the dissolved air release area 2 through the upper end of the overflow weir 50; the dissolved air releaser 18 generates a large number of fine bubbles through the decompression release of the dissolved air tank 11, which fully contacts the suspended flocs in the water, so that the suspended flocs in the water adhere to the microbubbles to form scum, and the aqueous solution with scum flows into the scum separation area 3 through the upper end of the first overflow retaining wall 51; after waiting for a period of time, the scum on the liquid surface passes through the upper end of the second overflow retaining wall 52 and overflows into the biochemical reaction area 4; the upper scum is scraped to the mud discharge area 5 by the mud scraping mechanism 13; the water at the bottom passes through the hydrophilic biological filter material 17 in the aeration tank, and the water body is further purified by using the microorganisms enriched on the hydrophilic biological filter material; the purified water flows into the clean water area 6 through the water collecting pipe 16 at the bottom, and overflows to the water outlet area 7 through the water level regulating gate 24 on the clean water area. Finally, a pump 25 returns the purified water in the water outlet area 7 to the river.

[0037] During normal operation, water intake and aeration are synchronized. The river water passes through the dosing mixing area, dissolved air release area, scum separation area, biochemical reaction area, and mud discharge area in turn. It reacts with the biofilm attached to the filler in an aerobic environment to remove some pollutants such as ammonia nitrogen, and then enters the clean water area through the bottom water collection pipe.

[0038] In the scum separation area, since the lower part of the scum separation area is connected to the lower part of the biochemical reaction area, and the upper part of the scum separation area is connected to the upper part of the biochemical reaction area, the water in the scum separation area enters the biochemical reaction area through the lower part, and the scum floats on the water surface. The scraping mechanism operates to scrape the scum on the water surface into the mud discharge area.

[0039] The operation time of this equipment can be set according to the river application scenario. At the same time, the dosing flotation section (including dosing mixing area 1, dissolved air release area 2, and scum separation area 3) and the filler biological aeration section can be operated independently or in series to meet the requirements of more complex river water quality sensory improvement. The system will shut down when the normal system runs for 200 hours or the set value, and the sludge discharge pipeline will be opened for the gravity discharge process of the settled sludge. After completion, normal operation will resume.

[0040] This equipment is equipped with a smart management platform. In the case of automatic operation, the control system obtains the turbidity index of the inlet and outlet water through the turbidity meter, and dynamically adjusts the dosage of the agent according to the flow rate of the inlet electromagnetic flowmeter and the turbidity index, thereby controlling and improving the effluent water quality of the flotation section. After the scum is separated, the river water enters the biochemical reaction zone, and further removes pollutants from the aeration layer, filler layer, etc. through the microorganisms attached to the filler to improve the effluent water quality. At the same time, the real-time operation status and alarm information can be transmitted back to the smart management platform in real time through 4G signals.
