Processing system and processing method for integrated grey water recycling of railway vehicle

Abstract

The invention relates to a processing system and a processing method for integrated grey water recycling of a railway vehicle. The processing method comprises the following steps: A, collecting grey water discharged by a grey water drainage device through a grey water collecting unit; B, detecting the turbidity index of the collected grey water, controlling the grey water in the grey water collecting unit to be directly exhausted to a dirt box through a blow-off pipeline when the turbidity index reaches a set value, and controlling the grey water in the grey water collecting unit to enter a subsequent grey water treatment unit when the turbidity index is lower than the set value; and C, filtering the gray water to form a reusable reclaimed water, and using the reclaimed water to flush toilets. According to the invention, effective recovery treatment is carried out on the grey water discharged by the grey water discharging devices such as toilets and the like on a railway vehicle, and the treated reclaimed water is used to flush the toilets, so that the secondary utilization of the water resource is realized, simultaneously the problems of short maintenance period, no resistance toimpact load and the like of the grey water treatment unit are solved, the volume of a clean water tank can be relatively reduced, and then the total weight of the vehicle is reduced.

Description

technical field [0001] The invention belongs to a railway vehicle water supply and drainage sanitation system, in particular to an integrated gray water reuse treatment system and a treatment method for a railway vehicle. Background technique [0002] At present, the sewage on high-speed rail and other railway vehicles, whether it is toilet flushing water or hand washing water, is supplied by the clean water tank on the vehicle, and then collected by the dirt tank, and transported to the sewage treatment plant for treatment after arriving at the station. Because some sites are far away from the sewage treatment plant, the transfer is inconvenient. At the same time, a certain fee must be paid for the transfer and delivery to the sewage treatment plant. If all or part of the sewage can be treated and reused, it will generate great economic benefits and reduce labor costs. cost. In addition, the existing railway vehicles directly discharge the gray water after washing hands to...

AI Technical Summary

Problems solved by technology

In addition, the existing railway vehicles directly discharge the gray water after washing hands to the dirt tank, and do not recycle this part of the gray water, which causes waste of clean water to a large extent. Water requirements require a larger volume of clean water tank, which also increases the weight of the vehicle to a certain extent
