Wastewater recycling system

Abstract

The invention relates to a wastewater recycling system which comprises a main water tank, a water storage tank, a wash basin, a water drawing tank, a closestool, a water pumping device and a water replenishing control device, the main water tank, the wash basin and the water drawing tank are all positioned above the water storage tank and are all communicated with the water storage tank through pipelines; the closestool is communicated with the water drawing tank through a pipeline; a first electromagnetic valve is arranged between the main water tank and the water drawing tank, a water pumping device and a second electromagnetic valve are arranged between the water storage tank and the water drawing tank, and a flushing switch is arranged between the water drawing tank and the closestool; the water replenishing control device is used for opening the first electromagnetic valve to replenish water to the water storage tank when the water level in the water storage tank is detected to be lower than a first preset low water level, and is used for opening the water pumping device and the second electromagnetic valve to replenish water to the water drawing tank when the water level in the water drawing tank is detected to be lower than a second preset low water level. According to the invention, the washing water is collected into the water storage tank for flushing the toilet, so that the water can be saved, and the waste of water resources is reduced.

Description

technical field [0001] The invention relates to the technical field of wastewater recycling equipment, and more particularly, to a wastewater recycling system. Background technique [0002] With the rapid development of society and the acceleration of urbanization, the problem of water shortage is becoming more and more serious, and water conservation and waste water recycling have gradually been paid attention to. In daily life, the waste water used by people after washing their hands and vegetables is directly discharged, and these domestic waste water only contains a small amount of dirt, and the direct discharge causes great waste, and can be used for toilet flushing. [0003] Especially on railway passenger trains, as the speed of the passenger train increases, the stop time is shortened, and the interval between trains getting on the water is prolonged, resulting in the train being dissatisfied with the water at the station, and the passenger service is not in place. ...

AI Technical Summary

Problems solved by technology

In daily life, the waste water used by people after washing their hands and vegetables is directly discharged, and these domestic waste water only contain a small amount of dirt, and the direct discharge causes great waste, which can be used for flushing toilets

[0003] Especially on railway passenger trains, as the passenger train speeds up, the stop time is shortened, and the water filling interval of the train is extended, resulting in the train being full of water in the station, and the passenger service is not in place

In addition, passengers on the train do not pay attention to water conservation, and there is a waste of water, which often causes problems of insufficient water supply capacity and water shortage during the operation of the train

The waste water in the washbasin on the train has a low degree of pollution and can be used for flushing toilet urinals. However, the waste water in the existing train washbasin directly flows into the waste water tank, resulting in a large waste of water resources on the train.
