Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to a device for collecting and treating urban sewage. Background Art

[0002] In the field of urban sewage treatment, the collection and treatment of sewage is crucial to environmental protection and public health. However, the existing traditional sewage treatment equipment has many shortcomings in practical applications, especially in the mixing and separation efficiency of sewage and coagulants or flocculants, and the mixing efficiency of chlorinated disinfectants. These problems not only affect the effect and speed of sewage treatment, but also increase operating costs and environmental risks.

[0003] The traditional sewage treatment process usually includes multiple steps such as physical sedimentation, chemical coagulation, flocculation and biological treatment. Among them, the mixing of sewage and coagulants or flocculants is one of the key links. Its purpose is to condense suspended matter and soluble pollutants in the water into larger particles through chemical reactions, which is convenient for the subsequent separation process. However, existing mixing equipment often relies on simple agitators or static mixers. Although these methods can achieve a certain mixing effect, the mixing time is long and the uniformity is not high. Due to insufficient mixing, some pollutants fail to condense effectively, thereby reducing the treatment efficiency of subsequent sedimentation or filtration units, and may even cause the effluent to still contain a high concentration of suspended matter, which cannot meet the discharge standards.

[0004] Traditional mixing methods lack flexibility in treating sewage of different types and concentrations. Due to the wide range of sewage sources and complex and variable composition, the water quality of different batches may vary greatly. Existing equipment usually uses fixed mixing parameter settings, which are difficult to dynamically adjust according to actual conditions. For example, when facing high concentrations of organic pollutants or heavy metal ions, if the mixing conditions cannot be optimized in time, it may lead to excessive or insufficient amounts of coagulants or flocculants, which not only wastes pharmaceutical resources, but also may cause secondary pollution. Therefore, improving mixing efficiency and accuracy has become a technical problem that needs to be solved urgently.

[0005] In the final stage of sewage treatment, it is usually necessary to add chlorinated disinfectant to kill pathogenic microorganisms in the water and ensure the safety of the effluent. However, traditional chlorinated disinfection systems mostly use a simple injection method and lack an effective mixing mechanism, resulting in insufficient contact time and mixing uniformity between the chlorinated disinfectant and sewage. This not only affects the disinfection effect, but may also lead to excessive or low residual chlorine content. The former will have potential harm to the environment and ecosystem, while the latter will fail to completely eliminate pathogens and threaten public health. Especially when dealing with large-scale sewage flows, this problem of low mixing efficiency is more obvious, increasing the risk of meeting discharge standards.

[0006] Therefore, how to provide a device for collecting and treating urban sewage is an urgent problem to be solved by those skilled in the art. Summary of the invention

The rotation of the wheel group 13012 drives the rotation of the filter valve plate 13013. The rotation of the filter valve plate 13013 moves the trapped suspended matter, colloidal substances, heavy metal ions and other pollutant flocs to the sewage rectangular pipe 10. The suspended matter, colloidal substances, heavy metal ions and other pollutant flocs enter the sewage rectangular pipe 10. Through the continuous rotation and coordination of the power motor 1202 and the filter motor 13011, the suspended matter, colloidal substances, heavy metal ions and other pollutants in the sewage are separated into first filtered water and pollutant flocs. The first filtered water enters the drainage rectangular pipe 9, the pollutant flocs enter the sewage rectangular pipe 10, and the first filtered water enters the water transfer pipe 14 through the drainage rectangular pipe 9.

[0059] Pollutant flocs such as suspended matter, colloidal substances and heavy metal ions in the rectangular sewage pipe 10 enter the sewage tube 22. The sewage motor 2301 is started to rotate the rotating shaft to drive the sewage bevel gear 2302 to rotate. The rotation of the sewage bevel gear 2302 drives the rotation of the sewage rotating rod 2303. The rotation of the sewage rotating rod 2303 drives the spiral blade 2304 to rotate, and the pollutant flocs such as suspended matter, colloidal substances and heavy metal ions are discharged from the sewage tube 22 for easy collection.

[0060] The centrifugal pump 15 is started to pump the first filtered water in the water transfer pipe 14 into the biological filter 3 , and the flow meter 16 detects the flow rate of the water flow in the water transfer pipe 14 .

[0061] The biological filter 3 uses the sewage treatment technology of microbial degradation of organic pollutants to filter the first filtered water to form the second filtered water, and the second filtered water is supplied to the filter box 8 of the biological filter 3 through the water supply pipe 7 of the biological filter 3; the chemical treatment unit supplies the filter box 8 located at the biological filter 3, and the chemical supplied by the chemical treatment unit is chlorinated disinfectant, and the chemical infusion pipe 19 supplies the chlorinated disinfectant. The second filtered water and the chlorinated disinfectant are mixed and disinfected in the filter box 8, and the water supply pipe 7, the filter box 8, the drainage rectangular pipe 9, the sewage rectangular pipe 10, the support frame 11, the power component 12, the filter component 13, and the water transfer pipe 14 at the biological filter 3. , the centrifugal pump 15 and the flow meter 16 filter the second filtered water and the chlorinated disinfectant mixture, the third filtered water enters the drainage rectangular pipe 9, the second filtered water containing a little impurities is trapped at the inner bottom of the filter box 8, the second filtered water with a little impurity enters the sewage rectangular pipe 10, the second filtered water in the sewage rectangular pipe 10 flows back to the biological filter 3, the third filtered water in the drainage rectangular pipe 9 enters the water transfer pipe 14, the third filtered water in the water transfer pipe 14 enters the sterilization pool 4, the ultraviolet lamp in the sterilization pool 4 and the equipment related to ultrasonic cell wall rupture perform effective sterilization, and the clean water is discharged from the outlet pipe 5 in the sterilization pool 4.

[0062] The present invention improves the efficiency of sewage treatment. By mixing sewage and a coagulant or flocculant, pollutant flocs such as suspended matter, colloidal substances and heavy metal ions in the sewage are quickly separated. The curved piston 1201 slides vertically up and down in the filter box 8. During the rising process of the curved piston 1201 in the filter box 8, a negative pressure is generated inside the filter box 8 to extract sewage and the coagulant or flocculant to mix in the filter box 8. During the descending process of the curved piston 1201 in the filter box 8, the pollutant flocs are separated, so that the first filtered water enters the drainage rectangular tube 9, and the pollutant flocs enter the sewage discharge rectangular tube 10, effectively saving the mixing and separation time of the sewage and the coagulant or flocculant.
