[0021] Referring to "embodiment" herein means that a specific feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0022] An embodiment of the present utility model provides a treatment device for high-concentration, high-salt, and high-chromaticity sewage, as Figures 1-4As shown in the figure, it includes a treatment tank 1; and a treatment tower 2 provided beside the treatment tank 1; wherein, the treatment tank 1 is divided into three cavities which are arranged in parallel and not connected to each other by a partition plate 3; the three cavities are, in the processing order, a filtration tank 4, a pretreatment tank 5 and a secondary treatment tank 6 in sequence; a main water guide pipe 7 is connected to the upper position of the treatment tower 2 opposite to the treatment tank 1; the main drainage pipe extends to the inner positions of the three cavities and is connected with a secondary water guide pipe 8; a fine filtration net 9 is arranged at the upper position inside the treatment tower 2, and the fine filtration net 9 is inclined; a screw rod sliding table 10 is arranged at the top position of the treatment tower 2; the moving end of the screw rod sliding table 10 extends to the inner cavity position of the treatment tower 2 and is provided with an electric push rod 11; a cleaning broom 12 is arranged at the telescopic end of the electric push rod 11; a slag collection port 29 is connected to the side of the treatment tower 2 away from the treatment tank 1.

[0023] It should be noted that, due to the significant drawback of insufficient treatment efficiency in traditional sewage treatment methods when dealing with sewage, that is, they can neither efficiently purify the water body nor meet the strict environmental protection standards and reuse requirements. This solution realizes the comprehensive and in-depth removal of pollutants in sewage through integrating multi-level filtration and treatment steps, combining an efficient stirring and mixing mechanism and an automated maintenance system; in particular, the treatment tower 2 is internally provided with a quartz sand layer 17, an activated carbon layer 18 and an ultrafiltration membrane layer 19, which purify the sewage step by step, ensuring that the effluent quality meets or even exceeds the strict discharge standards and meets the reuse requirements, thus showing significant advantages in environmental protection and water resource conservation.

[0024] At the same time, the coordinated work of the stirring shaft 13 and the stirring fan 27 not only effectively promotes the full mixing and dispersion of the sewage, prevents blockage and sedimentation problems, but also greatly improves the contact efficiency and fusion degree between the chemical agent and the sewage, ensuring the uniform, consistent, efficient and stable treatment effect; in addition, the automated cleaning device equipped in the treatment tower 2 can regularly clean the dirt on the fine filtration net 9, maintain the filtration efficiency, prevent blockage, and further consolidate the stability and reliability of the treatment system.

[0025] Specifically, in this embodiment, this solution mainly includes a treatment tank 1; and a treatment tower 2 provided beside the treatment tank 1; the sewage first enters the filtration tank 4 of the treatment device through the water inlet pipe 21; in the filtration tank 4, the sewage undergoes a preliminary physical filtration process, which aims to remove larger particles and suspended matters in the sewage and lighten the burden for subsequent treatment steps; after the preliminary filtration, the water quality of the sewage is improved to a certain extent, creating more favorable conditions for subsequent treatment.

[0026] Subsequently, the filtered sewage flows into the pretreatment tank 5 through the water guiding auxiliary pipe 8; in the pretreatment tank 5, chemical treatment is carried out according to the specific characteristics of the sewage; for example, adding agents to adjust the pH value of the sewage, implementing the flocculation precipitation process, etc., to remove some dissolved substances, colloids, and fine suspended solids in the sewage, and effectively reduce the chromaticity of the sewage; for high-salt sewage, this step is particularly important because salts have a significant inhibitory effect on the subsequent biological treatment process; after the pretreatment is completed, the sewage continues to flow to the secondary treatment tank 6; in the secondary treatment tank 6, an advanced oxidation process is adopted to further remove pollutants such as organic matter, nitrogen, and phosphorus in the sewage;

[0027] Finally, the sewage after secondary treatment is introduced into the treatment tower 2 through the main water guiding pipe 7 for advanced treatment; an inclined filter fine mesh 9 is arranged inside the treatment tower 2, and this fine mesh can efficiently intercept suspended solids and impurities in the sewage to ensure further improvement of the effluent water quality; however, over time, a certain amount of dirt will inevitably accumulate on the filter fine mesh 9; in order to maintain the filtering effect and prevent blockage, the treatment tower 2 is also equipped with automatic cleaning devices such as a screw slide table 10, an electric push rod 11, and a cleaning broom 12; when cleaning is required, the screw slide table 10 drives the electric push rod 11 and the cleaning broom 12 to move along the filter fine mesh 9, sweep the dirt on it, and collect and process it through the slag collection port 29, so as to ensure the continuous and efficient operation of the treatment tower 2.

[0028] In a further preferred embodiment of the present utility model, as Figure 3 shown, a stirring shaft 13 is rotatably fitted at the middle position of the inner cavity of the treatment tower 2, stirring blades 14 are arranged on the outer side of the stirring shaft 13, a first motor 15 is arranged on the outer side of the treatment tower 2, and the output end of the first motor 15 is key-fixed to the end of the stirring shaft 13.

[0029] In this embodiment, the added stirring shaft 13 and stirring blades 14 in the treatment tower 2, driven by the first motor 15, achieve sufficient mixing and dispersion of the sewage through rotation and stirring, improve the treatment effect and prevent blockage and deposition from occurring.

[0030] In a further preferred embodiment of the present utility model, as Figure 3 shown, a filter layer 16 is arranged at the lower position of the inner cavity of the treatment tower 2. The filter layer 16 is successively a quartz sand layer 17, an activated carbon layer 18, and an ultrafiltration membrane layer 19 from top to bottom. A drain pipe 20 is connected to the lower position of the treatment tower 2 far from the treatment pool 1.

[0031] In this embodiment, the quartz sand layer 17 serves as the first layer of the filtration layer 16, mainly playing a role in coarse filtration. The quartz sand particles are uniform, having good interception ability and permeability, and can effectively remove large particulate matters, suspended matters and some colloidal substances in the sewage, reducing the turbidity of the sewage. The activated carbon layer 18 is located below the quartz sand layer 17, mainly using the strong adsorption performance of activated carbon to remove organic matters, chromaticity and some heavy metal ions in the sewage. Under the drive of pressure, when the sewage passes through the ultrafiltration membrane layer 19, the micropores on the ultrafiltration membrane only allow water molecules and extremely small solute molecules to pass through, while pollutants larger than the membrane pore diameter are intercepted on the membrane surface or within the membrane pores, thereby realizing the deep purification and separation of the sewage. The water quality of the effluent from the ultrafiltration membrane layer 19 is high, capable of meeting more stringent discharge standards or reuse requirements. The drain pipe 20 is used to discharge the clear water treated by the filtration layer 16.

[0032] In a further preferred embodiment of the present utility model, as Figure 3 shown, a water inlet pipe 21 communicating with its inner cavity is provided at the end side of the filtration tank 4; a plurality of grilles 22 are provided in the filtration tank 4, and the plurality of grilles 22 are arranged in parallel; an ultraviolet germicidal lamp 23 is provided on one side of the filtration tank 4 away from the grilles 22.

[0033] In this embodiment, the sewage first enters the filtration tank 4 through the water inlet pipe 21. After entering the filtration tank 4, the sewage first encounters the parallelly arranged grilles 22. These grilles 22 can effectively intercept large particulate matters, suspended matters and some impurities in the sewage, such as plastic bags, branches, sediment, etc. The sewage filtered by the grilles 22 continues to flow forward and enters the ultraviolet sterilization area. In this area, the ultraviolet germicidal lamp 23 emits high-intensity ultraviolet rays. These ultraviolet rays can penetrate the thin layer of the sewage and destroy the DNA structure of microorganisms such as bacteria and viruses, making them lose their reproductive ability, thereby achieving the purpose of sterilization and disinfection. After the sewage is treated by ultraviolet sterilization, its biological pollution load is significantly reduced and the water quality is initially improved.

[0034] In a further preferred embodiment of the present utility model, as Figures 1-3 shown, filter coarse meshes 24 are provided at the lower positions of the pretreatment tank 5 and the secondary treatment tank 6.

[0035] In this embodiment, the filter coarse mesh 24 is provided at the lower position of the secondary treatment tank 6; the filter coarse mesh 24 here effectively intercepts and deposits the impurities in the flowing sewage below it, thereby preventing these impurities from being accidentally sucked away by the subsequent water guiding auxiliary pipe 8 and brought into the subsequent treatment unit or discharged into the environment; such a design not only improves the purification efficiency of the entire sewage treatment system, but also enhances the stability of the effluent water quality.

[0036] In a further preferred embodiment of the present utility model, as Figures 1-3As shown, a first pump body 25 is provided on the main water guide pipe 7, and a second pump body 26 is provided on each of several secondary water guide pipes 8.

[0037] In this embodiment, the first pump body 25 is used to control the main water guide pipe 7, and the second pump body 26 is used to control the secondary water guide pipes 8 and each cavity. The first pump body 25 and the second pump body 26 achieve effective liquid transportation and distribution through coordinated work.

[0038] In a further preferred embodiment of the present utility model, as Figures 1-3 shown, stirring fans 27 are rotatably fitted in the inner cavities of the pretreatment tank 5 and the secondary treatment tank 6, and a set of second motors 28 are provided outside the treatment tank 1. The output ends of the two second motors 28 are key-fixed to the ends of the corresponding stirring shafts 13.

[0039] In this embodiment, the second motor 28 drives the stirring fan 27 to rotate, causing the stirring fan 27 to start rotating in the tank. The rotation of the stirring fan 27 not only directly generates the power of the water flow, causing the sewage in the tank to form eddies and circulate, but also breaks the static state of the sewage through strong stirring, effectively promoting the mixing of the sewage and the uniform distribution of suspended solids. When chemical agents need to be added for further treatment, the rotation of the stirring fan 27 becomes particularly important. It can not only accelerate the water flow but also ensure that the chemical agents are quickly and evenly dispersed into the sewage, thus effectively promoting the full contact and deep integration of the chemical agents and the sewage. This mixing effect not only improves the reaction efficiency of the agents but also ensures the uniformity and stability of the treatment effect.

[0040] Working principle: When this device is in use, sewage is first introduced into the filtration tank 4 through the water inlet pipe 21; in the filtration tank 4, the sewage encounters the parallelly arranged gratings 22, which effectively intercept large particles, suspended solids, and some impurities in the sewage, such as plastic bags, branches, sediment, etc., thus achieving preliminary physical filtration; after being filtered by the gratings 22, the water quality of the sewage is improved to a certain extent. The sewage after being filtered by the gratings 22 continues to flow forward and enters the ultraviolet sterilization area. In this area, the ultraviolet sterilization lamp 23 emits high-intensity ultraviolet light rays, which can penetrate the thin layer of sewage and destroy the DNA structures of microorganisms such as bacteria and viruses, making them lose their reproductive ability, thereby achieving the purpose of sterilization and disinfection. After being treated by ultraviolet sterilization, the biological pollution load of the sewage is significantly reduced, and the water quality is preliminarily improved;

[0041] Subsequently, the preliminarily filtered sewage flows into the pretreatment tank 5 through the water guiding auxiliary pipe 8; in the pretreatment tank 5, according to the specific characteristics of the sewage, a series of chemical treatments are carried out, such as adding chemicals to adjust the pH value of the sewage, implementing the flocculation precipitation process, etc., to remove some dissolved substances, colloids, and fine suspended solids in the sewage, and effectively reduce the chromaticity and salt content of the sewage; these treatment measures are particularly important for the subsequent biological treatment process because they can significantly reduce the burden on the biological treatment system;

[0042] After the pretreatment is completed, the sewage continues to flow to the secondary treatment tank 6; in the secondary treatment tank 6, advanced treatment technologies such as advanced oxidation processes are used to further remove pollutants such as organic matter, nitrogen, and phosphorus in the sewage; in order to enhance the treatment effect, a stirring shaft 13 and stirring blades 14 are also provided in the secondary treatment tank 6 and the treatment tank, and they rotate and stir under the drive of the first motor 15, so that the sewage is fully mixed and dispersed, preventing blockage and sedimentation, and promoting the full contact and deep integration of chemical agents and sewage;

[0043] Then, the sewage after secondary treatment is introduced into the treatment tower 2 for advanced treatment; an inclined filtering fine mesh 9 is provided inside the treatment tower 2, which can efficiently intercept suspended solids and impurities in the sewage, ensuring the further improvement of the effluent quality; in order to maintain the filtering effect and prevent blockage, an automatic cleaning device such as a screw slide table 10, an electric push rod 11, and a cleaning broom 12 is also equipped in the treatment tower 2 to regularly clean the dirt on the filtering fine mesh 9;

[0044] Inside the treatment tower 2, a filtering layer 16 composed of a quartz sand layer 17, an activated carbon layer 18, and an ultrafiltration membrane layer 19 is also provided; the sewage passes through these filtering layers 16 in sequence and is gradually purified; the quartz sand layer 17, as the first layer, mainly plays a role in coarse filtration; the activated carbon layer 18 uses its strong adsorption performance to remove organic matter, pigments, and some heavy metal ions; the ultrafiltration membrane layer 19 realizes the advanced purification and separation of the sewage through its microporous structure, and the effluent quality is high, which can meet more stringent discharge standards or reuse requirements;

[0045] In the whole treatment process, the first pump body 25 and the second pump body 26 achieve the effective transportation and distribution of the liquid through coordinated work; the first pump body 25 is mainly used for the control of the main water guiding pipe 7, while the second pump body 26 is used for the control of the water guiding auxiliary pipe 8 and each cavity; finally, the treated clear water is discharged through the drain pipe 20.
