Water entering from the A end enters the second sand filter 3 from the bottom of the second sand filter 3 through the switching pipe 10, the K14 valve, the backwashing pipe 8, the K10 valve and the water pipe 11, then the water is discharged from the B end through the water pipe 11 and the K11 valve after coming out from the top of the second sand filter 3, and backwashing on the second sand filter 3 is realized.
When the first sand filter 2 is backwashed and the second sand filter 3 works normally, the K6 valve, the K7 valve, the K8 valve, the K9 valve, the K14 valve and the other valves are all closed, water entering from the A end enters the second sand filter 3 from the top of the second sand filter 3 through the switching pipe 10, the K14 valve, the working pipe 7, the K6 valve and the water pipe 11, and then water exits from the bottom of the second sand filter 3 through the water pipe 11 and the K7 valve and then exits from the C end, so that the normal work of the second sand filter 3 is realized. Water entering from the A end enters the first sand filter 2 from the bottom of the first sand filter 2 after passing through the backwashing pipe 8, the K8 valve and the water pipe 11, and then is discharged from the B end after passing through the water pipe 11 and the K9 valve from the top of the first sand filter 2, so that backwashing on the first sand filter 2 is realized.
When the sand in the first sand filter 2 is loosened after backwashing or the second sand filter 3 is washed, the water flow needs to be pressed downwards, and the K12 valve or the K13 valve is opened to compact the sand in the filter screens of the respective sand filters (the filter screens are arranged at the bottoms of the first sand filter 2 and the second sand filter 3), so that the water is discharged from the end B.
The application provides a changeable sand filtration system of series connection realizes each function through switching each valve when using: the water filtered by the former sand filter enters the next sand filter, so that the dirt in the water can be effectively filtered, and the water inlet load of the DTRO equipment is reduced; when a current sand filter dirt is stifled, can change valve work with the next sand filter of back, the previous sand filter of backwash simultaneously, so exchange mutually. The whole system and the DTRO equipment do not need to be shut down, so that backwashing or maintenance of the corresponding sand filter can be realized, normal operation of the system and the service efficiency of the DTRO equipment can be ensured, and the sewage treatment efficiency is improved.
