Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a biochemical treatment device for wastewater purification. Background Art

[0002] Wastewater purification is an important part of environmental protection and sustainable development. Its technical means and equipment selection have a decisive influence on the treatment effect and resource utilization efficiency. Among the many wastewater treatment methods, biochemical treatment equipment has received widespread attention and application due to its high efficiency, environmental protection and sustainability. Biochemical treatment equipment is designed based on biochemical principles. It mainly uses the metabolism of microorganisms to decompose organic matter in wastewater. Under a suitable environment, microorganisms convert organic matter in wastewater into inorganic matter through adsorption, oxidation, decomposition and other processes, thereby purifying wastewater. Compared with physical or chemical methods, this method has better treatment effects and lower energy consumption, so it has been widely used in the field of wastewater treatment.

[0003] Some existing wastewater biochemical treatment equipment, when in use, although gradually purifies wastewater through a series of treatment tanks, is not designed with special sampling points or sampling systems, making it difficult for operators to easily obtain wastewater samples from different treatment links, and thus unable to accurately evaluate the treatment effect and adjust the treatment process.

[0004] For example, a wastewater biochemical treatment device disclosed in the announcement number CN205328813U, the biological treatment unit in the wastewater biochemical treatment device of the patent, including an anaerobic tank, a biological denitrification tank and an aerobic tank, can be treated in stages for different pollutants, greatly improving the treatment efficiency of wastewater. In particular, the setting of the biological denitrification tank can effectively remove nitrogen elements in wastewater and reduce nitrogen pollution to the environment. As a deep treatment unit, the MBR reaction tank, combined with membrane separation technology, can further remove tiny particles and soluble substances in wastewater to ensure that the effluent water quality reaches a higher standard. Adding PAC and PAM to the dosing pool can effectively remove suspended matter and colloidal substances in wastewater and further improve the clarity of wastewater. The setting of the dosing system ensures the uniform addition of PAC and PAM, avoiding the problem of excessive or insufficient. When the device is in operation, it can make full use of the metabolism of microorganisms to treat wastewater. Compared with physical and chemical methods, it has lower operating costs and is environmentally friendly.

[0005] However, the device also has certain shortcomings, especially in the sampling and testing of wastewater treatment. It is impossible to sample and test wastewater at different treatment stages. Wastewater biochemical treatment is a complex process, which requires sampling and testing of wastewater at different treatment stages in order to understand the treatment effect and adjust the treatment parameters. However, the device is not designed with special sampling points or sampling systems, making it difficult for operators to easily obtain wastewater samples at different treatment stages, making it impossible to accurately evaluate the treatment effect and adjust the treatment process, which may affect the efficiency of wastewater treatment and the stability of effluent water quality.

[0036] Working principle of this utility model:

[0037] Refer to the instruction manual Figure 1-4 When using the utility model, firstly, the wastewater to be treated is injected into the filter tank 2 through the water injection pipe 17, and the wastewater is preliminarily filtered through the filter screen plate 18 in the filter tank 2 to remove larger impurities;

[0038] The filtered wastewater is pumped into the sedimentation tank 3 through a water pump and a pipeline, and a corresponding flocculant is added to the sedimentation tank 3 through a feeding pipe 22. During this process, a stirring paddle 20 is driven by a driving motor 21 to rotate in the sedimentation tank 3 to promote the mixing of the wastewater and the flocculant, so that the suspended matter in the wastewater agglomerates and gradually settles under the action of gravity. The sewage pipe 25 at the bottom of the sedimentation tank 3 is used to discharge the sediment to ensure the cleanliness of the wastewater in subsequent treatment;

[0039] The supernatant in the sedimentation tank 3 is pumped into the degradation tank 4 through a water pump and a pipeline, and corresponding microorganisms are added to the degradation tank 4 through a feeding pipe 22. In this process, the stirring paddle 20 is driven by a driving motor 21 to rotate in the degradation tank 4 to promote the mixing of wastewater and microorganisms, and the organic matter in the wastewater is decomposed by the metabolism of microorganisms;

[0040] The degraded wastewater in the degradation tank 4 is pumped into the purification tank 5 through a water pump and a pipeline. After entering the purification tank 5, the wastewater comes into contact with the activated carbon particles 23. The activated carbon can effectively remove pollutants such as heavy metal ions, color, and odor in the wastewater, thereby improving the effluent quality.

[0041] The purified wastewater in the purification tank 5 is pumped into the disinfection tank 6 through a water pump and a pipeline, and a corresponding disinfectant is added to the disinfection tank 6 through a feeding pipe 22. In this process, the stirring paddle 20 is driven by a driving motor 21 to rotate in the disinfection tank 6 to promote the mixing of the wastewater and the disinfectant, and the pathogenic microorganisms in the wastewater are killed by the disinfectant;

[0042] After the wastewater has been treated and meets the discharge standard or the reuse requirement, it is discharged through the drain pipe 26 at the bottom of the disinfection pool 6;

[0043] During the treatment process, the micro water pump 9 can be operated through the control panel 16 to take samples in the filtration tank 2, the sedimentation tank 3, the degradation tank 4, the purification tank 5 and the disinfection tank 6 respectively. The sampled wastewater is measured by the electronic flow meter 10 and discharged into the sample cup 15 through the sample discharge pipe 13 for subsequent testing and analysis.
