Description

[Technical Field]

[0001] This utility model belongs to the field of water treatment technology, specifically relating to the technology for treating sewage discharge from outlets. [Background Technology]

[0002] Currently, there is a lack of effective methods for treating stormwater overflows. Traditional treatment processes suffer from high costs and poor applicability, and existing in-situ pretreatment measures cannot meet the needs of water storage and treatment. Therefore, it is urgent to develop efficient and adaptable river pollution control technologies.

[0003] Among numerous treatment technologies, the "three-pond, two-dam" system is a commonly used technique in aquaculture wastewater treatment and is also widely applied in river water treatment. It consists of a sedimentation tank, a filter dam, an aeration tank, and a biological purification tank. The system is divided into three units by overflow and subsurface flow dams, treating aquaculture water to meet discharge standards or for recycling. The overflow dam blocks sedimented pollutants, increases surface flow, and raises water oxygen levels. The subsurface flow dam blocks suspended pollutants and provides a low-oxygen environment to promote the growth of anaerobic purification microorganisms, creating an aerobic and anaerobic microbial treatment model that enhances nitrification and denitrification, achieving the purification of total nitrogen and total phosphorus. It is widely used in aquaculture wastewater treatment and paddy field management. However, traditional "three-pond, two-dam" technology has drawbacks under the same water quality and quantity conditions, including large footprint, high energy consumption, short equipment lifespan, high maintenance costs, increased operating costs due to chemical use, long commissioning cycles, and poor shock resistance.

[0004] Therefore, there is an urgent need for a method to optimize traditional river overflow outlet treatment equipment and treat river polluted water directly in situ according to the original river structure. [Utility Model Content]

[0017] Preferably, the packing chambers in the first-stage filtration and oxidation zone, the second-stage filtration and oxidation zone, and the third-stage filtration and oxidation zone, as well as the top of the fourth-stage filtration zone, are provided with fiberglass grating.

The main body of the equipment is installed on a reinforced concrete foundation, forming a whole with a compact structure.

Detailed Implementation Methods

[0031] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0032] Those skilled in the art will understand that, without conflict, the features in the following embodiments and implementations can be combined with each other.

[0033] The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. For example, terms such as "upper," "lower," "inner," and "outer," which indicate orientation or positional relationship, are based solely on the orientation or positional relationship shown in the accompanying drawings and are used only for the convenience of describing the invention and simplifying the description. They do not indicate or imply that the device / component referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the invention.

[0034] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0035] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0036] This implementation method involves in-situ remediation based directly on the existing river channel structure, such as... Figures 1 to 6As shown, an ecological treatment system for the discharge outlet is installed along the river channel. This system comprises, sequentially arranged from upstream to downstream along the river's flow direction: inlet tank 15 → first-stage filtration and oxidation zone 11 → second-stage filtration and oxidation zone 12 → third-stage filtration and oxidation zone 13 → effluent tank → fourth-stage filtration zone 14. It primarily treats suspended solids and phosphorus in the discharge outlet through processes such as filtration, adsorption, contact oxidation, and plant adsorption. After treatment by this system, the main pollutants in the effluent—ammonia nitrogen, total phosphorus, and COD—are effectively reduced, decreasing the overall pollution load on the river.

[0037] The discharge outlet ecological treatment equipment adopts a modular quick-assembly structure. The internal structure is divided into zones according to various treatment functions, with corresponding functional modules for each zone. These functional zones are assembled into a complete unit through modular assembly. A reinforced concrete foundation 10 is provided at the bottom. The first-stage filtration and oxidation zone, second-stage filtration and oxidation zone, third-stage filtration and oxidation zone, and fourth-stage filtration zone of the inlet pool are all independent modular structures, assembled and installed on the reinforced concrete foundation. Mounting bases 104 for fixing the bottom of each module are fixed to the reinforced concrete foundation using expansion bolts. The reinforced concrete foundation is located on a crushed stone cushion layer. The crushed stone cushion layer serves to drain water and evenly distribute pressure, while the reinforced concrete foundation provides solid and stable support for the equipment, adapting to silty geological conditions and ensuring safe operation of the equipment in different geological environments.

[0038] Specifically, the first-stage filtration and oxidation zone, the second-stage filtration and oxidation zone, the third-stage filtration and oxidation zone, and the fourth-stage filtration zone are all independent rectangular modular structures, while the inlet tank is an independent right-angled trapezoidal modular structure. This facilitates the assembly of each module on a reinforced concrete foundation. Furthermore, the inlet tank has a 45° inclined water-facing surface. This design effectively reduces the impact force of water flow on the tank body, lowers the risk of water flow damage to the equipment structure, and extends the equipment's service life.

[0039] The ecological treatment equipment for the discharge outlets uses segmented prefabricated standard modules for rapid assembly of each functional area. Each module is connected by high-strength bolts and sealant, with expansion joints between modules filled with EPDM rubber strips. The modules are standardized in size, material, and manufacturing process, reducing construction quality issues caused by human factors. The number, length, and combination of modules can be flexibly adjusted according to site conditions. Factory prefabrication reduces on-site cutting and welding, lowering noise, dust, and waste emissions. The modular construction reduces on-site labor requirements, resulting in an overall cost reduction of 20%-30% compared to traditional methods.

[0040] Specifically, each module includes an overall frame constructed from fiberglass square tubes 101 and PP panels 103 serving as outer walls and internal partitions. Pipe connectors 102 can be installed between the sections of fiberglass square tubes 101, which can be straight pipes, bends, tees, etc., as needed. The overall frame uses corrosion-resistant fiberglass square tubes. Fiberglass is lightweight, high-strength, and has excellent corrosion resistance, reducing the overall weight of the equipment while meeting structural support requirements. PP panels are mainly used for the outer walls and internal partitions of the equipment. PP panels have good chemical corrosion resistance, impact resistance, and insulation properties.

[0041] The inlet tank is used for pretreatment of the incoming water. The packing chambers in the first-stage filtration and oxidation zone, the second-stage filtration and oxidation zone, and the third-stage filtration and oxidation zone perform a dual function of physical filtration and chemical adsorption to remove impurities and harmful components from the incoming water. The contact oxidation chamber is equipped with biological packing and has an aeration pipe 113 at the bottom for aeration, utilizing microorganisms to biodegrade organic matter and ammonia nitrogen in an aerobic environment. The fourth-stage filtration zone is filled with an activated carbon packing layer for further purification of the incoming water.

[0042] The first-stage filtration and oxidation zone is equipped with a first-stage packing chamber 111 and a first-stage contact oxidation chamber 112 (or aeration chamber). The second-stage filtration and oxidation zone is equipped with a second-stage packing chamber 121 and a second-stage contact oxidation chamber 122. The third-stage filtration and oxidation zone is equipped with a third-stage packing chamber 131 and a third-stage contact oxidation chamber 132. Furthermore, the multiple packing chambers and contact oxidation chambers in the first, second, and third-stage filtration and oxidation zones are staggered, specifically staggered perpendicular to the river channel direction.

[0043] The inlet tank pre-treats the incoming water; the packing chambers in the first-stage filtration and oxidation zone, the second-stage filtration and oxidation zone, and the third-stage filtration and oxidation zone perform a dual function of physical filtration and chemical adsorption to remove impurities and harmful components from the incoming water. The contact oxidation chamber has biological packing suspended on the inner surface and aeration pipes at the bottom for aeration, utilizing microorganisms to biodegrade organic matter and ammonia nitrogen in an aerobic environment.

[0044] The packing chambers in the first, second, and third stage filtration and oxidation zones are equipped with phosphorus-removing ceramic granules. Each of these zones has a four-layer structure: from bottom to top, a volcanic rock layer, a double-layer phosphorus-removing ceramic granule layer, and a layer of phosphorus-removing flakes. The various types of packing materials are packaged in eco-bags and then layered. The functions of the first to third stage packing chambers are: to physically filter and intercept larger particulate impurities in the water, while providing a habitat for microorganisms; to efficiently adsorb and chemically precipitate phosphorus from the water; to further filter and stabilize water flow; and to effectively intercept fine particles in the water.

[0045] The fourth-stage filtration zone is filled with an activated carbon packing layer 141 for further purification of the incoming water. The activated carbon packing layer 141 is located in the lower part of the fourth-stage filtration zone, while a layer of sunflower seed chips 142 is located at the top. In this way, the fourth-stage filtration zone has a strong adsorption capacity for residual microparticles, pigments, odor substances, and some dissolved organic matter in the water, further purifying the water quality and ensuring that the effluent meets high standards.

[0046] The biological packing material used in the contact oxidation chambers of the first, second, and third stage filtration and oxidation zones must have a large specific surface area to allow for the attachment of a large number of microorganisms and the formation of a biofilm. Microorganisms grow and reproduce on the biofilm, decomposing and metabolizing organic matter and ammonia nitrogen in the water. The aeration system evenly introduces air into the contact oxidation chamber through microporous aeration pipes, providing sufficient oxygen to the microorganisms, maintaining an aerobic environment, promoting microbial growth and metabolic activity, and improving biodegradation efficiency.

[0047] The primary function of the inlet pool 15 is to balance the water volume, ensuring a relatively stable flow into the equipment and preventing excessive fluctuations that could impact subsequent treatment modules. Simultaneously, the incoming water is diverted through two side flow channels into the first-stage filtration and oxidation zone. Two screens, coarse and fine, are installed before the flow channels to intercept debris, including algae and other debris that can easily grow in dry pipes. The coarse and fine screens are designed for easy cleaning and are secured by limiting devices, facilitating regular cleaning of intercepted debris and ensuring effective filtration. Furthermore, floating plants 151 are planted within the inlet pool to absorb and accumulate pollutants in the water to a certain extent. The leaves of these floating plants also beautify the landscape and enhance its aesthetic value.

[0048] The water outlet trough is equipped with an adjustable water-retaining baffle plate (height adjustable) at the water inlet end, which serves to store water and maintain the overall water level in the device during periods without overflow, ensuring the normal survival of microorganisms in the contact oxidation chamber. A spray system is installed at the top of the water outlet trough to remove any floating foam remaining in the effluent.

[0049] Furthermore, the first, second, and third stage filtration and oxidation zones, as well as the fourth stage filtration zone, are equipped with air-blowing perforated pipes. Compressed air is periodically introduced into the packing chambers through these pipes to backwash the packing. This blows up and carries away impurities trapped in the packing pores, preventing blockage and ensuring the effective treatment of the packing chambers. Additionally, the entire air-blowing system includes an air compressor and a pressure gauge. The air compressor provides sufficient pressure and flow of compressed air to the air-blowing perforated pipes to ensure effective backwashing of the packing chambers. The pressure gauge monitors the air pressure output by the air compressor in real time, allowing operators to adjust the compressor's operating parameters as needed to ensure the backwashing effect.

[0050] Furthermore, fiberglass grating is installed on the top of the packing chambers in the first, second, and third stage filtration and oxidation zones, as well as the fourth stage filtration zone. Workers can access the packing chambers through the grating for inspection, packing replacement, and other operations, facilitating equipment maintenance.

[0051] The system includes flow channels 16 between the inlet tank and the first-stage filtration and oxidation zone, between the first-stage and second-stage filtration and oxidation zone, and between the second-stage and third-stage filtration and oxidation zone. Therefore, the main treatment process and functional zoning are as follows: Inlet tank → Flow channel 1 → (First-stage packing chamber + First-stage contact oxidation chamber) → (Second-stage packing chamber + Second-stage contact oxidation chamber) → Flow channel 2 → (Third-stage packing chamber + Third-stage contact oxidation chamber) → Outlet tank → Fourth-stage filtration zone. Specifically, the effluent flows into the inlet tank through a pipe. In the inlet tank, coarse and fine screens sequentially intercept large suspended particles in the water. Then, the water flows through flow channel 1 into the first-stage packing chamber, where it undergoes preliminary purification through physical filtration and chemical adsorption. Next, it enters the first-stage contact oxidation chamber, where microorganisms biodegrade organic matter and ammonia nitrogen in an aerobic environment. Afterward, the water flows through flow channel 2 and then sequentially through the second-stage and third-stage packing chambers and the contact oxidation chamber for further deep treatment to remove pollutants. The treated water flows into the effluent tank, where a spray system removes any scum. Finally, the fourth-stage filtration zone, as an emergency backup measure, uses activated carbon to adsorb residual pollutants before being discharged in compliance with standards.

[0052] The above technical solution connects multiple areas in sequence for ecological treatment equipment at the discharge outlet to work together. Compared with the traditional "three pools and two dams" technology, it reduces the land area occupied, improves efficiency, and enhances the ability to withstand impacts.

[0053] Phosphorus removal ceramsite, which can be produced using existing technology, is spherical in shape with numerous micro- and nanopores inside. It possesses characteristics such as high porosity, high strength, large adsorption capacity, and fast adsorption rate. The ceramsite's physical microstructure features a rough, porous surface, making it particularly suitable for the growth and reproduction of microorganisms. Its internal nanoscale network structure exhibits extremely strong adsorption properties, allowing it to release Fe from phosphorus-containing wastewater. 3 + can react chemically with PO43- to form a chemical bond. Phosphate ions can also undergo ligand exchange reactions with the hydroxyl groups (-OH) on the surface of the phosphorus removal ceramic particles to form an inner-sphere complex. The formation of this chemical bond allows phosphorus to be firmly adsorbed onto the surface of the Fe-based sludge ceramic particles, thereby achieving phosphorus removal.

[0054] In biological nitrogen removal processes, especially nitrification and denitrification reactions, electron transfer is a crucial step in phosphorus removal ceramsite. Fe-based sludge ceramsite can act as a medium for electron transfer. Some Fe(II) / Fe(III) redox pairs can participate in the metabolic processes of nitrifying and denitrifying bacteria, accelerating the electron transfer rate and thus improving the efficiency of nitrification and denitrification reactions.

[0055] Phosphorus-removing ceramic particles possess a large specific surface area and suitable pore structure, providing excellent attachment and growth sites for denitrifying microorganisms. Microorganisms can form biofilms on their surface and within the pores. This biofilm structure facilitates microbial aggregation and synergistic effects, enhancing the microorganisms' ability to treat nitrogen pollutants. The active sites on the surface of the phosphorus-removing ceramic particles can interact with enzymes or metabolites secreted by microorganisms, serving as active centers for microbial metabolism, enhancing enzyme catalytic activity, and promoting the conversion of nitrogen compounds. Iron ions on the surface of the ceramic particles can bind to nitrifying enzymes, altering the enzyme's spatial structure and making its oxidation of ammonia nitrogen more efficient.

[0056] This invention incorporates biological packing material in the contact oxidation chambers of the first, second, and third stage filtration and oxidation zones. Microporous aeration pipes are laid at the bottom to aerate the wastewater, keeping the wastewater in agitated. The packing material tumbles within the chamber, ensuring ample contact between the wastewater and the packing material and preventing uneven contact. This improves oxygen transfer efficiency by over 30% and biofilm-wastewater contact efficiency by over 50%, significantly reducing aeration energy consumption. A high-pressure vortex blower can be connected to the aeration pipes to provide sufficient air to the contact oxidation chambers, meeting the oxygen requirements of aerobic microbial metabolism.

[0057] The fourth-stage filtration zone of this utility model serves as an emergency backup measure. It is filled with an activated carbon packing layer, which adsorbs residual pollutants and discharges them in compliance with standards.

[0058] Implementation Case 1:

[0059] Overflow outlet pretreatment project in a street in Qiantang District, Hangzhou City, Zhejiang Province: This embodiment uses a stormwater and sewage overflow outlet as the experimental object, and designs a new type of overflow outlet pretreatment device to regulate and treat the discharge from the outlet. This scheme designs a new type of outlet pretreatment device in Hezhuang Street, employing a river pollution treatment process combining physical adsorption and biological denitrification. The device includes, from front to back, an inlet tank → a first-stage filtration and oxidation zone → a second-stage filtration and oxidation zone → a third-stage filtration and oxidation zone → an outlet tank → a fourth-stage filtration zone.

[0060] The effective volume of the inlet pool is 10m³. 3 The hydraulic retention time is set to 1 hour, primarily for the initial sedimentation of large suspended particles and to balance the quality and quantity of the influent, reducing the impact on subsequent treatment units. The tank is equipped with coarse and fine screens to intercept larger floating objects. The first, second, and third stage filtration and oxidation zones have identical dimensions and structures.

[0061] Experimental Results and Analysis

[0062] After three months of continuous operation and monitoring, during the peak overflow period of the rainy season, the process achieved a COD removal rate of over 80%, a total nitrogen removal rate of over 75%, and a total phosphorus removal rate of over 85%. During non-overflow periods, the treatment effect was even more significant, with COD removal rates reaching over 90%, total nitrogen removal rates exceeding 85%, and total phosphorus removal rates exceeding 90%.

[0063] This utility model is a new process and equipment for the treatment of river overflow effluent that has been proven through engineering practice to be very low-carbon, energy-saving, long-lasting, efficient, and ecologically safe, and has a very broad application prospect.
