[0026] Combine the following Figures 1 to 3 , describing an embodiment of the utility model.

[0027] According to an embodiment of the utility model, a seawater filter sewage system is provided, comprising: a sewage pipeline 1, one end of which is suitable for communicating with a filter 2, and the other end of which is connected to a sewage outlet 3; a first valve 4, which is arranged on the sewage pipeline 1, and is suitable for controlling the on-off of the sewage pipeline 1, and thus controlling the sewage discharge work; the first valve 4 is an electric valve, which can be specifically an electric ball valve, and has the advantages of being able to accurately control the opening and closing state of the valve and avoid misoperation; a second valve 5, which is arranged on the sewage pipeline 1 and is independent of the first valve 4, and the second valve 5 is kept in an open state; the second valve 5 is a manual valve, which can be specifically a manual ball valve, so as to ensure system redundancy, retain manual operation, and improve the safety of system operation; the first valve 4 is arranged close to the sewage outlet 3 relative to the second valve 5; a regulating device 6, which is electrically connected to the first valve 4, and is suitable for regulating the opening and closing of the first valve 4, and the regulating device 6 can be an electric control cabinet, and the electric control cabinet can control the switching frequency and time of the first valve 4.

[0028] The structural form of the sewage pipeline 1 is that the sewage pipeline 1 includes a first pipeline 11 and a second pipeline 12; the first pipeline 11 and the second pipeline 12 are connected by means of a flange 7, the first pipeline 11 is also connected to the filter 2, and the second pipeline 12 is also connected to the sewage outlet 3; the first valve 4 and the second valve 5 are both arranged at the second pipeline 12; further, the first pipeline 11 is a rigid pipe suitable for bearing sewage pressure; the second pipeline 12 is a flexible pipe, specifically a PVC plastic pipe, that is, a pipe body made of polyvinyl chloride; the second pipeline 12 is suitable for selecting a second pipeline 12 of a suitable length according to the sewage outlet 3 at different positions, which is more suitable for actual working conditions and ensures that the sewage discharge needs are met; combined with Figure 2 and Figure 3 When installing the sewage system, it is necessary to select the second pipeline 12 of appropriate length in combination with the relative distance between the filter 2 and the sewage outlet 3. A long pipe is prepared for the long-distance sewage outlet 3, and a short pipe is prepared for the short-distance sewage outlet 3. The sewage system has strong compatibility.
