Safe environment-friendly secondary water supply facility which can easily clean and can recover clean waste water

Abstract

The invention provides a safe environment-friendly secondary water supply facility which can easily clean and can recover clean waste water. The safe environment-friendly secondary water supply facility includes a water tank, a water outlet pipe passing through water tank walls, a water pump connected to the water outlet pipe; a backup pipe and a backup water bank or a second water tank are connected to the water outlet pipe; a plurality of settling ponds are formed in a ground and communicate with each other through flow guide pipes / grooves. The backup water tank or two sets of water supplying devices which are directly connected in parallel can facilitate cleaning, can perform cleaning without stopping water supply, can facilitate residential life, can save the cleaning time, and can improve the efficiency; the clean waste water recovery facilities are arranged under the water tank, can recover waste water, and can reduce waste water drainage and avoid water resource waste; a lower position water outlet arranged on the water outlet pipe of the water tank and a movable cover plate can drain water in the water tank thoroughly while the water tank is cleaned, and can avoid waste.

Description

technical field [0001] The invention relates to a secondary water supply facility, in particular to a safe and environment-friendly secondary water supply facility that is convenient for cleaning and can recycle cleaning wastewater. Background technique [0002] Nowadays, most of the urban water supply in my country adopts the secondary water supply method, that is, clean water supply facilities are set up in residential areas with concentrated water supply, and the tap water from the urban water supply pipeline is concentrated and stored, and then the water pumps supporting the water supply facilities are used to pressurize the water twice to the households. The water storage device for secondary water supply is easy to deposit various impurities after long-term use. At the same time, there is usually a stagnant water layer in the lower part of the water storage device. The current method for cleaning the secondary water supply tank / pool is that professionals carry professi...

Problems solved by technology

The water storage device for secondary water supply is easy to deposit various impurities after long-term use. At the same time, there is usually a stagnant water layer in the lower part of the water storage device.

The disadvantage of this method is firstly that the cleaning workers must carry many operating tools such as consumption, spare water tanks, flushing hoses, etc., secondly, it affects the water consumption of residents, especially during the high temperature in summer, which has a great impact on the lives of residents; All waste water is discharged into urban sewer pipes, resulting in a waste of water resources, especially when cleaning large tanks or pools, it is often necessary to discharge dozens of tons of water
