[0025] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.

[0026] To this end, the applicant designed Figure 1-2 The shown device is an integrated drainage device for filtering and decontaminating rainwater on a waterfront platform or pier, comprising: an impurity filtering assembly, which is used to perform coarse and fine filtration on large particles of impurities in sewage, and the filtering assembly can be disassembled and cleaned when blocked by impurities; a sewage treatment assembly, which is used to perform secondary treatment on sewage filtered by the impurity filtering assembly, and the sewage treatment assembly is installed at the bottom of the impurity filtering assembly and can be detachably installed between the impurity filtering assembly and the impurity filtering assembly by bolts; the impurity filtering assembly and the sewage treatment assembly are both integrally arranged in the drainage curb 8.

[0027] The integrated drainage device for rainwater filtration and decontamination of the waterfront platform and pier of this embodiment is further optional, and the impurity filtering component includes: a guide plate 1, which is recessed downward and has a guide hole in the middle, and a steel grating 2 is provided on the surface of the guide plate 1; a guide pipe 7, which is fixedly arranged at the guide hole; a filter screen 3, which is arranged in the guide pipe 7, and the upper end is mounted on the guide hole by a card plate, and the filter screen 3 extends downward in a net bag shape; a filter plate 4, which is used for secondary filtration of the sewage filtered by the filter screen 3, and the filter plate 4 is screwed to the bottom of the guide pipe 7, and the mesh on the filter plate 4 is finer than the mesh of the filter screen 3.

[0028] The integrated drainage device for rainwater filtration and decontamination of the waterfront platform and pier of this embodiment is further optional, and the sewage treatment component includes: a filter box 5, the filter box 5 and the guide pipe 7 are installed at the bottom of the guide pipe 7, the bottom of the filter box 5 is connected to the sewer pipe, and a water outlet is provided at the bottom of the filter box 5; a filter element 6, the filter element 6 is arranged in the filter box 5 for filtering sewage.

[0029] The integrated drainage device for rainwater filtration and decontamination on waterfront platforms and piers of this embodiment further optionally comprises a filter element 6 made of granular carbon or volcanic stone. Both granular carbon and volcanic stone have porous structures with small pore sizes and large surface areas, capable of adsorbing and collecting small particulate matter and organic matter. Furthermore, both granular carbon and volcanic stone possess negatively charged functional groups on their surfaces, which can adsorb positively charged ions, heavy metal ions, and the like, removing them through electrostatic action. The physical adsorption process of granular carbon and volcanic stone is irreversible; once adsorbed onto the granular carbon and volcanic stone, it is difficult to release them, resulting in good stability.

[0030] The integrated drainage device for rainwater filtration and decontamination of the waterfront platform and pier of this embodiment is further optional, and each component can be detachably arranged.

[0031] Working principle: In the process of treating sewage, the sewage is first filtered through the steel grating 2 for the first time, and some larger impurities (such as leaves, etc.) can be filtered out; after the sewage enters the diversion pipe 7, it is filtered for the second and third time through the filter mesh 3 and the filter plate 4. The treated sewage enters the filter box 5 and is filtered for the fourth time through the filter element 6. The filtered sewage can be discharged into the sewer; when the drainage device needs to be cleaned, the operator only needs to hold the steel grating 2 to pull out the drainage assembly as a whole.

[0032] It is apparent for a person skilled in the art that the present application is not restricted to the details of the above exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary only, and not limiting, the scope of the present application being defined by the appended claims rather than the above description, and all changes coming within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference signs in the claims should not be construed as limiting the claims concerned.
