Description

Ash water recycling treatment device Technical Field The application relates to the technical field of reuse water treatment, in particular to a grey water reuse treatment device. Background For a train, grey water refers to water flowing down from a wash basin. Along with the gradual improvement of people's water conservation consciousness, the reuse of grey water is becoming more popular. On a train, the amount of clear water loaded per car is very limited due to limited space. The total water is needed to be provided for washroom, toilet for cleaning, and toilet for flushing, so the water consumption is very intense, and the utilization of gray water is more important. The amount of gray water generated on the train is usually 25% -40% of the total water consumption, and the gray water after the use of the washroom and the toilet basin and black water flushed by the closestool are discharged into a vehicle-mounted sewage box together, so that the design volume of the sewage box can be increased. And simultaneously, larger waste of water resources is caused. And the train needs to carry a large-volume water storage device to meet the water demand. In recent years, in order to save energy and protect environment, domestic high-speed rail motor cars gradually push out a grey water recycling device, recycle and reuse grey water, improve the utilization rate of the grey water, and effectively reduce the volume of a clean water tank and the sewage treatment capacity. However, in the existing train grey water treatment method, grey water generated on the train is filtered into reclaimed water capable of flushing a toilet by a filtering device, but in the using process, a filter element of the filtering device needs to be replaced frequently, so that maintenance cost is increased. The use of the ash water recycling device is that firstly, the service life of the filter element is a key factor, and any filtration and interception can block the filtration channel.
