Abstract

The invention discloses a train gray water treatment system and a treatment method, comprising: a gray water tank, the upper part of which is provided with a water inlet for connecting with a gray water source; a filter installed at the lower end of the side wall of the gray water tank; a reclaimed water tank, A filter branch and a recoil branch are connected between the outlet of the filter, the outlet of the filter branch communicates with the upper part of the reclaimed water tank, and the water inlet of the recoil branch connects with the lower part of the reclaimed water tank; the recoil branch The filter structure is backflushed through the filter structure of the filter branch. By backwashing the filter, the service life of the filter can be effectively improved, and the filter element of the filter device does not need to be replaced frequently, which reduces maintenance costs.

Description

technical field [0001] The invention relates to the technical field of train gray water treatment, in particular to a train gray water treatment system and a treatment method. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] Gray water generally refers to the water flowing from wash basins and floor drains. For trains, gray water refers to the water flowing down from wash basins. In recent years, in order to save energy and protect the environment, domestic high-speed trains have gradually introduced gray water recycling devices to recycle gray water and improve the utilization rate of gray water, which can effectively reduce the volume of clean water tanks and the amount ...
