2O
2Mix the complex cleaning and washing agent of forming with 3% citric acid.
This process adopts little flocculation fibre-ball filtration that hotel bathing waste water is carried out preliminary treatment, because the POLYESTER HIGH ELASTIC YARN fiber-ball filter media of independent development is more open on filtering layer top, the space is bigger between ball, more near the filtering layer bottom, fibrous nodules is because deadweight and hydraulic action are piled up closely knitly more, fiber interts mutually, has formed a fibrage integral body, and the top porosity of whole filtering layer is bigger, the bottom porosity is less, the distribution of pores of approximate ideal strainer, therefore better to the effect of bathing waste water filtering, add in development process, by to the selection of material and the test of material property, by the practice utilization, finally determine filametntary diameter and length simultaneously, and the contained fibre quantity of each fibrous nodules, therefore, after fibrous nodules lost efficacy, backwash effect was also better, thereby has also prolonged the cycle of operation of fibre-ball filtration.The present invention proposes " little flocculation POLYESTER HIGH ELASTIC YARN fibre-ball filtration, ultrafiltration, nanofiltration group technology ", membrane separation technique is compared traditional biological treatment, have flow process simple, take up an area of less, stable, be easy to characteristics such as management, and separative efficiency height, process are simple etc., can remove pollutants such as larger molecular organics in the water, graininess suspension.The group technology that the present invention proposes is to COD in the bath wastewater, turbidity, pollutants such as LAS higher removal all arranged, through the pretreated water outlet of little flocculation fibrous nodules again through milipore filter and disinfect after, effluent quality can reach " regeneration city, city miscellaneous water water quality " (GB/T18920-2002) in the hotel lavatory flushing, the water quality requirement of greening etc., the ultrafiltration water outlet continues advanced treating through nanofiltration membrane component again, after simultaneously sterile-processed, effluent quality can reach " drinking water sanitary standard " (GB5749-85), can do washing in reuse to hotel fully, the higher links of water water quality requirement such as bathing, thus reach the purpose of bath wastewater comprehensive recycling.
Specific implementation method of the present invention:
(1) operation processing section
Pending hotel bathing waste water filters through hair filter 5 earlier by pipeline 6, then with little flocculant rapid mixing pipe-line mixer 1 of squeezing into from dosing tank 4 by measuring pump 2, enter fiber ball filter 100 by pipeline 38 then, carry out filtration, purification through filtrate 74, water outlet after purifying enters hyperfiltration membrane assembly 78 through connecting pipe 82 with security personnel's filter core 14 by force (forcing) pump 81 and filters, part water outlet after the filtration is by pipeline 85,43,46, simultaneously through ClO
2Disinfection trough 58 sterilization reach " regeneration city, city miscellaneous water water quality " (GB/T18920-2002) require after, enter ultrafiltration and disinfect water outlet water storage tank 37, can reuse to links such as hotel lavatory flushing, greenings, partial concentration liquid refluxes by pipeline 91,13, increase the surface filtration filtering velocity of milipore filter, part is then discharged by pipeline 19; Remain the milipore filter water outlet through pipeline 85,44, force (forcing) pump 90, security personnel's filter core 96, pipeline 95 enter nanofiltration membrane component 92 and filter, and filter water outlet through pipeline 97,54, simultaneously through ClO
2Disinfection trough 58 sterilization reach " drinking water sanitary standard " (GB5749-85) after, enter nanofiltration and disinfect water outlet water storage tank 33, can reuse to higher links of water water quality requirement such as hotel laundry, bathings, partial concentration liquid refluxes by pipeline 31,24, increase the surface filtration filtering velocity of NF membrane, part is then discharged by pipeline 29.
(2) backwash part
Adopt ultrafiltration to disinfect storage water in the water outlet water storage tank 37 as backwashing water, open valve 35, current enter backwash water tank 9 by pipeline 99, squeeze into fiber ball filter 100 by submersible pump 68 through pipeline 67, simultaneously air by recoil air pump 10 through pipeline 71, squeeze into fiber ball filter 100 by aeration head 11 and carry out air-water backwashing, backwashing water is discharged through overfall 73, finally remains backwashing water by evacuated tube 12 emptyings.
When the milipore filter cyclic chemical cleaned, first valve-off 75,17,20,45 was opened valve 21,42, complex cleaning and washing agent in the chemical bucket 40 is by pipeline 72, force (forcing) pump 81, pipeline 82, security personnel's filter core 14, pipeline 80 enters hyperfiltration membrane assembly 78 and carries out Chemical cleaning, clean water outlet through pipeline 85,43, valve 42, pipeline 41 is back to cleaning agent bucket 40, and cleaning concentrate is by pipeline 91, valve 21, pipeline 89 also is back to cleaning agent bucket 40.
When the NF membrane cyclic chemical cleaned, first valve-off 22,27,30,53 was opened valve 32,49, cleaning agent in the chemical bucket 48 is by pipeline 47, force (forcing) pump 90, pipeline 88, security personnel's filter core 96, pipeline 95 enters nanofiltration membrane component 92 and carries out Chemical cleaning, clean water outlet through pipeline 97,50, valve 49, pipeline 103 is back to cleaning agent bucket 48, and cleaning concentrate is by pipeline 31, valve 32, pipeline 98 also is back to cleaning agent bucket 48.
