Water valve is produced in ultrafiltration；Described ultrafiltration module is connected with chemicals dosing plant, internal circulation pump in turn by chemical feed pipe；Described chemicals dosing plant, interior
Chemical feed pipe composition wash cycles pipeline described in circulating pump, bag filter.
Internal circulation pump can increase the flow velocity of ultrafiltration membrane surface, makes pollutant be not easy attachment.Three are placed in pump inlet
Platform chemicals dosing plant, can be separately added into such as the abluents such as NaOH, sodium hypochlorite, hydrochloric acid, when needs clean, the valve of ultrafiltration system
Door is closed, and opens internal circulation pump, and chemical agent injects chemicals dosing plant, circulates dosing a period of time, makes internal drug concentration reach
Shut down after certain degree, soak a few minutes.
Further, described ultrafiltration module connects hyperfiltration reverse-rinsing water inlet pipe and hyperfiltration reverse-rinsing outlet pipe, and described ultrafiltration is anti-
Wash and on water inlet pipe, be provided with hyperfiltration reverse-rinsing water intaking valve, described hyperfiltration reverse-rinsing outlet pipe is provided with hyperfiltration reverse-rinsing drain valve.Ultrafiltration
Connect on the hyperfiltration reverse-rinsing water inlet pipe of backwash water intake valve side and have hyperfiltration reverse-rinsing pump, the ultrafiltration of hyperfiltration reverse-rinsing water intaking valve water outlet side
Being also associated with bag filter on backwash water inlet pipe, described ultrafiltration is produced water valve and is connected with described hyperfiltration reverse-rinsing pump, described ultrafiltration
Produce water valve, described hyperfiltration reverse-rinsing pump, described hyperfiltration reverse-rinsing water intaking valve and bag filter and form anti-scavenger circuit.
Further, described bag filter includes PP polypropylene filter element, and filtering accuracy is 1-50 micron；Described ultrafiltration group
Being provided with PVDF hollow-fibre membrane in part, filtering accuracy is 0.02-0.15 micron.
Further, described ultrafiltration water inlet pipe and described hyperfiltration reverse-rinsing water inlet pipe are additionally provided with effusion meter.
Further, described hyperfiltration reverse-rinsing drain valve is communicated to sewage plant.
By such scheme, the present invention at least has the advantage that
1, whole chemical cycle cleans fully automatic operation, simple to operate.
2, cleaning performance is obvious: chemicals dosing plant adds a certain amount of chemical reagent, and after circulation immersion, ultrafiltration can be rapidly
Recover flux.
3, circulating technology in using, makes pollutant be difficult to be attached to ultrafiltration membrane filaments surface.
4, in anti-cleaning process, bag filter filters out large granular impurity, thus protects ultrafilter membrane.
Described above is only the general introduction of technical solution of the present invention, in order to better understand the technological means of the present invention,
And can be practiced according to the content of description, below with presently preferred embodiments of the present invention and coordinate accompanying drawing describe in detail as after.
Accompanying drawing explanation
