Description

Technical Field

[0001] This utility model relates to a sewage treatment device, specifically a sewage treatment device with an associated structure, belonging to the field of sewage treatment technology. Background Technology

[0002] Wastewater treatment refers to the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Industrial wastewater treatment refers to the cleaning and treatment of wastewater containing pollutants generated in industrial production to meet the discharge standards or water quality requirements stipulated by environmental regulations. The treatment process of industrial wastewater involves a variety of technologies and methods, and the choice depends on the nature of the wastewater, its source, and the target treatment effect.

[0003] Currently, industrial wastewater treatment projects mainly employ two advanced treatment technologies: ozone oxidation combined with aerated biological filters and Fenton oxidation combined with sedimentation filtration. The former is suitable for situations where ozone oxidation of wastewater pollutants is effective and the wastewater needs to be reused, while the latter is suitable for projects where wastewater does not need to be reused and sludge disposal costs are low. It is mainly used in wastewater treatment in industries such as chemical fiber, printing and dyeing, and papermaking. Existing biological filters are a typical process for wastewater treatment using the biofilm method, while aerated biological filters have many advantages such as high organic volumetric loading, no sludge bulking, and simple and compact structure. However, the above two types of wastewater treatment equipment occupy a large area, have high costs, and complex structures. Therefore, a wastewater treatment device with an integrated structure is needed.

[0004] Therefore, a wastewater treatment device with an associated structure is proposed here. Utility Model Content

[0005] This utility model proposes a sewage treatment device with an associated structure to solve the problems of large footprint, high cost, complex structure and large water consumption of existing sewage treatment equipment.

[0006] This utility model is achieved through the following technical solution: a sewage treatment device with an associated structure, including two septic tanks and an equalization tank connected to the septic tanks, an inlet pipe installed on the side of the septic tank, a sewage treatment system arranged on the right side of the equalization tank, an air source heating device arranged between the two sewage treatment systems, and the sewage treatment system including a sedimentation unit and a treatment unit arranged sequentially on one side of the equalization tank, and there are multiple treatment units, and multiple treatment units are all connected to the sedimentation unit;

[0007] The sedimentation unit includes a first sedimentation tank, a second sedimentation tank, a disinfection tank, a reclaimed water tank, and an equipment room. The first sedimentation tank and the second sedimentation tank are used to remove larger particles and activated sludge and fine particles, respectively. The reclaimed water tank is used to transport qualified reclaimed water to non-potable equipment.

[0008] The treatment unit includes aerobic tanks and anaerobic tanks arranged alternately. The first sedimentation tank is equipped with a return pipe, and the sludge in the first sedimentation tank is fed into the treatment unit through the return pipe and returned in the order of aerobic tank-anaerobic tank-aerobic tank-anaerobic tank.

[0009] The second sedimentation tank contains a precipitant, the disinfection tank contains sodium hypochlorite, and part of the sludge from the first sedimentation tank is transported to the septic tank through a return pipe.

[0010] There are two equipment rooms, and each equipment room is equipped with a blower and a graduated valve. The blower is used to provide sufficient oxygen to the aerobic tank. The blower is connected to the aerobic tank and anaerobic tank in multiple treatment units through connecting pipes.

[0011] The equalization tank is connected to multiple treatment units via conveying pipes. There are multiple graduated valves, and each graduated valve is installed on the surface of a corresponding conveying pipe. The equalization tank conveys wastewater to the aerobic tank and the anaerobic tank via the conveying pipes, so that it mixes with the sludge in the sedimentation tank and is returned.

[0012] The air source heat pump is equipped with a connecting pipe on its side. The connecting pipe contains antifreeze. The air source heat pump is used to heat the antifreeze. There are multiple air source heat pumps and multiple connecting pipes. The other end of each connecting pipe passes through the sedimentation unit and multiple treatment units in the two sewage treatment systems.

[0013] When the connecting pipe is installed inside the sedimentation unit, it passes through the equipment room, the recycled water tank, the disinfection tank, the second sedimentation tank, and the first sedimentation tank in sequence.

[0014] When the connecting pipe is installed inside the treatment unit, it passes through the anaerobic tank, the aerobic tank, the anaerobic tank, and the aerobic tank in sequence, and is installed back and forth to form a loop.

[0015] This utility model provides a wastewater treatment device with an associated structure, which has the following beneficial effects:

[0016] 1. This wastewater treatment device with an interconnected structure reduces the footprint by integrating the anaerobic zone, aerobic zone, and sedimentation zone into a single unit. It enhances the removal capacity of organic matter and pollutants such as nitrogen and phosphorus through sludge recirculation. At the same time, by recirculating the treated wastewater, the water quality within the reactor can be adjusted, providing a stable reaction environment and enhancing the treatment effect.

[0017] 2. This wastewater treatment device with an interconnected structure heats the antifreeze by installing an air-source heat pump, and the heated antifreeze is then placed inside the sedimentation unit and the treatment unit. At the same time, the two wastewater treatment systems are connected in parallel with the air-source heat pump, which ensures normal operation and solves the problems of large footprint, high cost, complex structure and large water consumption of existing wastewater treatment equipment.

[0031] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The second sedimentation tank 3012 contains a precipitant, and the disinfection tank 3013 contains sodium hypochlorite. Part of the sludge from the first sedimentation tank 3011 is transported to the septic tank 1 through a return pipe. There are two equipment rooms 3015, and each equipment room 3015 is equipped with a blower 30151 and a graduated valve 30152. The blower 30151 is used to provide sufficient oxygen to the aerobic tank 3021. The blower 30151 is connected to the aerobic tank 3021 and the anaerobic tank 3022 in the multiple treatment units 302 through connecting pipes.

[0032] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3The equalization tank 2 is connected to multiple treatment units 302 via conveying pipes. There are multiple graduated valves 30152, and the multiple graduated valves 30152 are respectively installed on the surface of the corresponding conveying pipes.
