Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, in particular to a rapid treatment facility for overflow sewage in rainy season. Background Art

[0002] With the rapid development of social economy, water pollution caused by the indiscriminate discharge of wastewater has caused serious damage to the ecological environment. Overflow sewage pollution is mainly concentrated in the rainy season, when rainwater mixed with a large amount of surface pollutants and urban domestic sewage overflow into the receiving water bodies.

[0003] Interception wells can intercept overflow sewage and flow it to sewage treatment plants. In order to treat the sewage, it is generally filtered through treatment equipment. Since the sewage contains garbage or impurities, it is easy to clog the filter net, affecting the filtration efficiency of the sewage and greatly reducing the practicality of the facility. Utility Model Content

[0004] The main technical problem solved by the utility model is to provide a rapid treatment facility for overflow sewage in rainy season, so as to ensure the treatment efficiency of overflow sewage.

[0005] In order to solve the above technical problems, a technical solution adopted by the utility model is: a rapid treatment facility for overflow sewage in rainy season, comprising a diverter trough, a filter plate and two filter bodies, wherein the diverter trough is located above the filter plate, the filter plate is located above the filter body, and the diverter trough, the filter plate and the filter body are all installed inside the sewage treatment tank;

[0006] The top surface of the sewage treatment tank is provided with a sewage inlet, and the bottom surface of the sewage treatment tank is provided with a water outlet;

[0007] The filter plate is a structure that gradually slopes downward from the center to both sides, and both sides of the filter plate are provided with collection grooves that open upward, and a collection frame is placed inside the collection groove. The upper end of the collection frame is provided with a collection port, and the collection port is communicated with the sewage treatment tank. The bottom surface of the collection groove is an inclined surface, and the collection frame and the inclined surface together constitute a reflux port, and the reflux port is located below the filter plate. The bottom surface of the collection frame is provided with a through hole, and the collection frame is communicated with the reflux port, and the reflux port is communicated with the sewage treatment tank. Due to the inclined design of the filter plate, garbage and large impurities fall into the collection frame under the impact of sewage, thereby preventing the filter plate from being blocked, quickly treating the sewage, and ensuring the filtering efficiency;

[0008] A plurality of nozzles are provided below the filter plate, and the nozzles are installed on an air pipe, and the air pipe is connected to an air pump, and the air pump is fixed to the outer wall of the sewage treatment tank, so as to blow air to the filter plate through the nozzles regularly to prevent the filter plate from being blocked;

[0009] The two filter bodies are respectively a packing filter body and an activated carbon filter body. The activated carbon filter body is located below the packing filter body, and the packing filter body is located below the filter plate. The packing filter body makes the falling sewage more evenly distributed, which is beneficial for the activated carbon filter body to further adsorb impurities in the sewage and ensure the sewage treatment effect.

[0010] Furthermore, two diversion ports are provided on the bottom surface of the diversion trough, the sewage inlet is connected to the diversion trough, the diversion channel is connected to the diversion port, and the diversion port is connected to the sewage treatment tank.

[0011] Furthermore, the collecting frame is provided with a lifting handle.

[0012] Furthermore, the filter body includes an external supporting mesh plate and fillers or activated carbon particles located inside the supporting mesh plate.

[0013] Furthermore, the sewage treatment tank is provided with a chute matching the filter body, and the filter body is installed in the chute.

[0014] Furthermore, it also includes a fixing plate, through which screws pass to fix the fixing plate to the sewage treatment box to prevent the filter body from sliding out of the chute.

[0015] Furthermore, a plurality of supporting legs are provided at the bottom of the sewage treatment tank.

[0016] The beneficial effects of the present invention include at least the following points:

[0017] The filter plate of the utility model is a structure that gradually tilts downward from the center to both sides. Both sides of the filter plate are provided with collection grooves with openings upward, and a collection frame is placed inside the collection groove. After the sewage enters the sewage treatment box, it is filtered through the filter plate. Due to the inclined design of the filter plate, garbage and large impurities fall into the collection frame under the impact of the sewage, thereby preventing the filter plate from being blocked, quickly processing the sewage, and ensuring the filtering efficiency. It is worth mentioning that a plurality of nozzles are provided under the filter plate, and the nozzles are installed in the air pipe, and the air pipe is connected to the air pump, so that air is blown to the filter plate through the nozzle regularly to prevent the filter plate from being blocked;

[0018] The two filter bodies of the utility model are respectively a filler filter body and an activated carbon filter body. The filler filter body makes the falling sewage more evenly distributed, which is beneficial for the activated carbon filter body to further adsorb impurities in the sewage, thereby ensuring the sewage treatment effect;

[0019] The utility model also comprises a fixing plate, and screws pass through the fixing plate and are fixed to the sewage treatment box to prevent the filter body from sliding out of the slide groove, thereby facilitating the replacement of the filter body. BRIEF DESCRIPTION OF THE DRAWINGS
