The emptying of extraction raffinate body.
The course of work that the present embodiment high temperature fills the water fine filtration device is as follows:
(1) normal filtration process:
Water enters double medium filters 2 by pneumatic ball valve, and double medium filters 2 carry out primary filter to water, it
Enter fiber ball filter 3 afterwards, fiber ball filter 3 carries out secondary filtration to water, through the filtered water of fiber ball filter 3
The pretreatment before ultrafiltration is carried out through cartridge filter 4, pretreated water enters ultrafiltration apparatus 5 and carries out fine processing, after processing
Water through pneumatic ball valve by 6 remittance abroad of outlet pipe；Still ensure that effluent quality is steady when water water quality is poor using three-stage filtration
Surely reach reinjected water A1 grade standard；
It should be noted that ultrafiltration is dense when water enters fiber ball filter 3 by the filtering of double medium filters 2
Water reflux pump 8 pumps the concentrated water of ultrafiltration apparatus 5 into the connecting tube between double medium filters 2 and fiber ball filter 3, so that
The concentrate recirculation water of ultrafiltration apparatus 5 and the water for passing through double medium filters 2 are collaborated, and the dense of ultrafiltration apparatus 5 can not only be made
Water recirculation water is refiltered by fiber ball filter 3, while can also reduce the temperature of water, is convenient for subsequent ultrafiltration device 5
Filtering；High temperature resistant ultrafiltration membrane is used inside ultrafiltration apparatus 5, guarantees that ultrafiltration membrane remains to work normally when water quality temperature is higher；
(2) counter-flushing process of ultrafiltration apparatus 5:
Upper backwash process: the backwashing water of ultrafiltration apparatus 5 is ultra-filtration water, and ultra-filtration water is pumped through outlet pipe 6, hyperfiltration reverse-rinsing
7 and the water outlet of ultrafiltration apparatus 5 enter the backwash regeneration that ultrafiltration apparatus 5 carries out film, sewage backwash water finally fills through ultrafiltration
The side water outlet for setting 5 tops pumps water pot 12 in 8 entrance through ultrafiltration concentrate recirculation by ultrafiltration sewage backwash pipe 15, as double media
The backwash water of filter 2 and fiber ball filter 3；
Lower backwash process: the backwashing water of ultrafiltration apparatus 5 is ultra-filtration water, and ultra-filtration water is pumped through outlet pipe 6, hyperfiltration reverse-rinsing
7 and the water outlet of ultrafiltration apparatus 5 enter the backwash regeneration that ultrafiltration apparatus 5 carries out film, sewage backwash water finally fills through ultrafiltration
The water inlet for setting 5 bottom ends pumps water pot 12 in 8 entrance through ultrafiltration concentrate recirculation by ultrafiltration sewage backwash pipe 15, as double medium mistakes
The backwash water of filter 2 and fiber ball filter 3；
The backwash of ultrafiltration apparatus 5 is carried out using upper backwash and lower backwash two ways, from both direction to ultrafiltration apparatus 5
In ultrafiltration membrane cleaned, enhance the effect of backwash, ensure that can be more thorough by ultrafiltration Membrane cleaning；
Ultrafiltration medicine wash journey:
When Pollution of Ultrafiltration Membrane in ultrafiltration apparatus 5 is serious, medicine need to be carried out to ultrafiltration apparatus 5 and washed, medicament pickling tank 9, alkali cleaning
Tank 10 washes pump 11 through medicine and enters ultrafiltration apparatus 5 to ultrafiltration membrane progress backwash and regeneration, and backwash water passes back into pickling tank 9 through outlet pipe 6
With caustic treater 10；
(3) counter-flushing process of double medium filters 2 and fiber ball filter 3:
The backwash water of double medium filters 2 and fiber ball filter 3 is the sewage backwash water of ultrafiltration apparatus 5, in
Sewage backwash water in water pot 12 respectively enters fiber ball filter 3 and double medium mistakes after the promotion of filter recoil pump 13
Filter 2 carries out the backwash and regeneration of filtrate, and sewage backwash water is finally discharged through backwash sewage pipe；
Using ultrafiltration apparatus 5 sewage backwash water as double medium filters 2 and fiber ball filter 3 backwash come
The backwash water amount of device entirety is greatly saved in water.
