Description

Technical Field

[0001] The utility model relates to the technical field of domestic sewage treatment equipment, in particular to a domestic sewage treatment equipment with a group of modular filtering units. Background Art

[0002] A large amount of domestic sewage such as kitchen waste, washing, and toilet is generated in human life. The domestic sewage contains a large amount of organic matter and a considerable number of pathogenic microorganisms. If directly discharged, it will pollute the soil, groundwater, surface water and breed a large number of pests such as mosquitoes and flies. Therefore, it is necessary to treat the domestic sewage so that the water quality meets the external discharge standard.

[0003] The domestic sewage in human concentrated residential areas is collected and treated centrally in sewage treatment plants. However, for places where people live scattered, such as in the wild construction sites, which are remote and where human settlements are scattered, it is impossible to achieve centralized treatment of domestic sewage. Only integrated domestic sewage treatment equipment can be used at each settlement point to treat domestic sewage, and the treated water quality meets the discharge standard.

[0004] Conventional integrated domestic sewage treatment equipment combines an anoxic unit, an aerobic unit, a sedimentation unit, a filtering unit, a disinfection unit, etc. into a functional equipment to complete the up-to-standard treatment of domestic sewage. Among them, the filtering unit is mainly composed of a quartz sand filtering layer and an activated carbon filtering layer. The quartz sand filtering layer further filters the impurities in the treated water body, and the activated carbon filtering layer effectively adsorbs organic pollutants, residual chlorine, odor, etc. in the water to ensure that the effluent water quality meets the standard. However, when the filtering unit works for a long time, impurities will be generated in the filter layer, clogging the quartz sand filter layer and the activated carbon filter layer, or causing the activated carbon filter layer to lose its adsorption function, resulting in the over-standard of the treated water quality or the inability of the sewage to be treated to enter the filtering unit, causing water blockage in the equipment. Therefore, it is necessary to replace the quartz sand filter material and the activated carbon filter material. The replacement of the filter material in the filtering unit of the conventional integrated domestic sewage treatment equipment requires workers to enter the equipment body to remove the filter material, wash the inner cavity of the equipment filter material and refill the filter material. Not only is the working environment harsh, the labor intensity is high, and the efficiency is low, but also a large amount of fresh air needs to be provided inside the equipment to prevent safety accidents for workers. The replacement of the filter material requires the cooperation of multiple people to complete. For places where the installation position of the integrated domestic sewage treatment equipment is narrow and mechanical power tools cannot enter, the labor intensity is even greater, the filter material replacement time is longer, and it is even possible that the filter material cannot be replaced.

[0066] When the equipment of the utility model treats the domestic sewage generated in human scattered residential areas such as field construction sites, small-scale natural villages, and highway service areas, the domestic sewage is collected in the regulating tank and then pumped into this equipment by a pump. The domestic sewage undergoes anaerobic unit 19 and aerobic unit 20 in the equipment for phosphorus and nitrogen removal. After removing a large amount of organic matter, there will be a large amount of suspended matter in the domestic sewage. The domestic sewage then enters the sedimentation unit 21. After most of the suspended matter is sedimented in the sedimentation unit 21, the sewage containing a small amount of suspended matter enters the filtration unit 2. The sewage first enters the bottom of the quartz sand grouped module filtration unit of the filtration unit 2, and enters the upper fine quartz sand grouped module 4 from the bottom coarse quartz sand grouped module 3, effectively intercepting and removing suspended matter, organic matter, colloidal particles, etc. in the water, reducing the water turbidity and purifying the water quality.

Each quartz sand grouped module and activated carbon grouped module 5 are configured with sponge gaskets to ensure that all water to be filtered passes through the quartz sand and activated carbon filter layers. The water discharged from the filtration unit 2 is concentrated in the water collection bin 27, and the water discharged from the water collection bin 27 is disinfected by an ultraviolet disinfection device and then discharged up to the standard.

[0067] During the long-term operation of this equipment, the quartz sand and activated carbon filter media in the filtering unit 2 will be blocked, and the liquid level detector and the on-line water quality detection unit 28 will automatically give an alarm to prompt the replacement of the filter media. When replacing the filter media, first stand the rotary hoisting device 6 folded on the top of the equipment upright on the top of the equipment, then hook the hook of the hand winch 9 into the lifting holes of each group of modules of the filtering unit 2, and turn the hand winch 9 to lift the grouped modules of the filtering unit 2 out of the equipment and rotate the rotary hoisting device 6 to hoist the grouped modules to the ground beside the equipment. Workers remove the filter media in the grouped modules on the ground, wash the grouped modules, and then load the new filter media into the grouped modules. The new filter media can be transported to the site by a manual trolley, without being restricted by the narrow installation position of the equipment and the situation where power machinery cannot enter. After the replacement of the new filter media is completed, the grouped modules of the filtering unit 2 are installed in place by using the rotary hoisting device 6, so as to achieve the purpose of replacing the filter media without workers entering the interior of the equipment and being unrestricted by the installation position of the equipment.

[0068] Finally, it should be noted that the above are only the preferred embodiments of the present utility model, and are not used to limit the protection scope of the present utility model.
