Description

Technical Field

[0001] This utility model relates to the field of sewage treatment technology, specifically a sewage collection and treatment system for riverbanks. Background Technology

[0002] In recent years, with economic development and urbanization, the discharge of industrial and domestic wastewater has increased year by year. Many residential areas, especially in older urban areas, are located along rivers. These scattered settlements make wastewater collection difficult, and the integrated domestic sewage network is inadequate, leading to the indiscriminate discharge of domestic sewage into rivers, severely impacting their self-purification capacity. Furthermore, numerous enterprises are located along rivers, including heavily polluting industries such as leather factories, waste oil processing plants, and electroplating plants. The wastewater discharged by these heavily polluting enterprises has a significant impact on river water quality. For example, wastewater from leather factories exhibits large fluctuations in water quality and quantity, high suspended solids concentration, and is prone to spoilage, resulting in substantial pollution. The wastewater contains toxic compounds such as nitrogen, phosphorus, sulfides, and cadmium. Oil spills from waste oil processing plants also severely pollute water bodies, causing oxygen depletion and a very long natural degradation cycle for the oil. Electroplating wastewater not only exhibits acid-base variations but, if not thoroughly treated, can contain pollutants such as cyanide, ammonia, salicylic acid, and heavy metals. These pollutants, including high levels of COD, ammonia nitrogen, sulfides, and heavy metals, not only directly pollute water bodies, but also fundamentally disrupt the ecological balance of water bodies because many of these pollutants are biologically toxic.

[0003] Although the existing patent CN206346298U discloses a sewage collection and treatment system for riverbanks that can solve the above problems, during operation, large impurities (such as leaves) in the sewage may cause blockages in the sewage collection branch pipes or main sewage collection pipes. Therefore, a sewage collection and treatment system for riverbanks is invented. Utility Model Content

[0004] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0014] As a preferred embodiment of the sewage collection and treatment system around a river as described in this utility model, the sweeping component includes:

[0015] T-shaped block, the T-shaped block being threadedly connected to the top of the inner cavity of the separator tube;

[0016] A rotating shaft is rotatably connected to a T-block via a bearing;

[0017] A water wheel is fixedly mounted on a rotating shaft, and an inlet pipe is provided on one side of the water wheel.

[0018] As a preferred embodiment of the sewage collection and treatment system around a river as described in this utility model, the sweeping component further includes:

[0019] A square plate is fixedly installed on the bottom side wall of the rotating shaft;

[0020] The square plate has several brush bristles on one side, and the brush bristles can come into contact with the filter screen after rotation.

[0023] Compared with existing technologies:

[0034] The sewage collection main pipe 2 is hung on the riverbank. A sewage pump 10 is installed on the connecting pipe between the sewage collection main pipe 2 and the water collection tank 4. An inlet valve 101 and an outlet valve 102 are respectively installed on the pipes on both sides of the sewage pump 10.

[0035] The biological treatment unit includes an anaerobic treatment zone 5, an anoxic treatment zone 6 and an aerobic treatment zone 7 arranged sequentially along the water flow direction. The aerobic treatment zone 7 is equipped with a dynamic aeration device 71. The water treated in the aerobic treatment zone 7 is discharged into the river through a drainage pipe, which is equipped with a drainage valve 9.

[0036] The filtration unit includes: a separation pipe 100, an inlet pipe 110, an outlet pipe 120, and a filter screen 140;

[0037] A valve is provided at the bottom of the separator 100. The top left side of the separator 100 is fixedly connected to the inlet pipe 110, and one end of the inlet pipe 110 is fixedly connected to the drain outlet 22 through a flange. The middle right side of the separator 100 is fixedly connected to the drain pipe 120, and one end of the drain pipe 120 is fixedly connected to the sewage collection branch pipe 21 through a flange. Liquid flow sensors are provided in the inner cavities of both the drain pipe 120 and the inlet pipe 110. A filter screen 140 is fixedly installed in the inner cavity of the other end of the drain pipe 120.

[0038] The filtration unit also includes a cleaning component for treating impurities attached to the filter screen 140, and the cleaning component is disposed in the separation tube 100;

[0039] The cleaning components include: T-shaped block 200, rotating shaft 210, water wheel 220, square plate 230, and brush bristles 240;

[0040] The T-shaped block 200 is threaded onto the top of the inner cavity of the separator 100. A sealing ring can be provided at the connection between the T-shaped block 200 and the separator 100 as required. The rotating shaft 210 is rotatably connected to the T-shaped block 200 through a bearing. The bearing is preferably the bearing in patent CN217736027U. The water wheel 220 is fixedly installed on the rotating shaft 210, and an inlet pipe 110 is provided on one side of the water wheel 220.

[0041] In practical use, the operating steps for those skilled in the art are as follows:

[0042] Industrial and domestic wastewater from the surrounding river is discharged into the sewage collection branch pipe 21 through the sewage outlet 22. The sewage in the sewage collection branch pipe 21 is collected into the sewage collection main pipe 2, and then the sewage is collected into the collection tank 4 by the sewage pump 10. It is then transported to the biological treatment unit, where the water is purified through anaerobic, anoxic and aerobic processes to make the water quality meet the Class A standard of the "Integrated Wastewater Discharge Standard". Finally, it is replenished into the river to alleviate the pollution load of the river 1.

[0043] When sewage is discharged into sewage collection branch pipe 21 through sewage outlet 22, it flows into separation pipe 100 through inlet pipe 110, and then into sewage collection branch pipe 21 through filter screen 140 and drain pipe 120. This allows for the filtration of large impurities (such as leaves) in the sewage. When sewage flows from inlet pipe 110 into separation pipe 100, it impacts water wheel 220, causing shaft 210 to drive square plate 230 to rotate. When square plate 230 rotates, it removes impurities attached to filter screen 140. When two sets of liquid flow sensors detect a significant difference between the liquid flow rate in drain pipe 120 and the liquid flow rate in inlet pipe 110, the impurities at the bottom of separation pipe 100 are discharged through valve.

[0044] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
