Ukusetyenziswa kwe-high-effective reverse osmosis membrane element kunyango lwamanzi amdaka

Itekhnoloji yokwahlula inwebu ye-RO

Itekhnoloji yokwahlula i-membrane ye-RO isebenzisa umahluko we-static yoxinzelelo kuyo yonke i-membrane njengamandla okuqhuba. Iimolekyuli ezincinci, ezinje ngeamolekyu zamanzi, zoyisa uxinzelelo lwe-osmotic ukuba zidlule kwi-membrane ye-RO, ngaloo ndlela zibahlukanise nokungcola. Uxinzelelo lokusebenza ngokuqhelekileyo phakathi kwe-1.5 kunye ne-10.5 MPa, kwaye inkqubo inokugcina iimolekyuli ezincinci ze-1 ukuya kwi-10A.

Kunyango lwamanzi, i-RO, njengesixhobo esibalulekileyo, inokususa ngaphezu kwe-97% ye-soluble inorganic matter, i-99% yezinto eziphilayo ezinobunzima be-molecular of 300 okanye ngaphezulu, ngaphezu kwe-99% yeengqungquthela ezahlukeneyo ezibandakanya ibhaktheriya, kunye ne-95% ye-SiO2 emanzini.

Owona mmandla mkhulu wesicelo wasekhaya we-reverse osmosis membranes uhlala usiba manzi kwibhoyila enkulu, elandelwa ngamashishini ahlukeneyo amanzi acocekileyo kunye neemarike zamanzi okusela. Izicelo ze-Membrane ziye zafikelela kwinqanaba elibalulekileyo kwi-electronics, i-semiconductor, i-pharmaceutical, unyango, ukutya, isiselo, utywala, iikhemikhali, ukhuseleko lokusingqongileyo, i-metallurgy kunye ne-textile. Izicelo ezinokuthi zibe kho kwixesha elizayo ziquka ukucocwa kwamanzi amdaka kumanzi okupholisa kwiziko lombane, ukukhutshwa kwetyuwa kumanzi olwandle ngomlinganiselo omkhulu, ukucocwa kwamanzi anetyuwa, kunye nokucocwa kwamanzi amdaka kumasipala nakwimizi-mveliso.

Ukusetyenziswa kwe-RO membrane kunyango lwamanzi amdaka

1Ukusetyenziswa kunyango lwamanzi amdaka anetyuwa eninzi

(1) Unyango olunempembelelo kumanzi amdaka anezimbiwa eziphezulu, amelwe ngamanzi asemgodini, luphawulwa bubutyuwa obuphezulu, ingakumbi ukuphuma kwamanzi aphantsi komhlaba, kunye nesiqulatho setyuwa esingaphezu kwe-1000 mg/L. Izinto eziphilayo ze-SS eziqulethe isixa esikhulu seCa2 + Mg2 + K +, Cl-, SO42-, HCO3 kunye neHCO3- ngaphantsi kwe-1.5 mg / L. Kwimimandla yemigodi enokunqongophala okukhulu kwamanzi, ukusetyenziswa kwetekhnoloji ye-osmosis ye-reverse kunyango olunzulu lwemveliso kunye namanzi asekhaya kuye kwakhuthazwa ngokubanzi.

Ukusebenzisa amanzi amaminerali njenge-agent agent, i-flocculation, i-sedimentation, kunye nokucoca ngokukhawuleza kongezwa ukuba kususwe ininzi ye-SSS emanzini, okubangelwa ukuguqulwa kwe-osmosis inlet turbidity engaphantsi kwe-1 NTU. Emva konyango lwe-osmosis ebuyela umva, izinga lokususa ukungcola kwamanzi amdaka lisondele kwi-100%, ngesantya sokukhupha ityuwa ngama-96%.

(2) Ukucocwa kwamanzi amdaka ngesinyithi

Ishishini lentsimbi, elinobutyebi obunzulu, elisebenzisa amanzi kakhulu nelingcoliseka kakhulu, libalelwa kwi-14% yokusetyenziswa kwamanzi xa ewonke e-China. Amanzi amdaka eshishini lesinyithi asetyenziswa kakhulu kwishishini lesinyithi. Amanzi amdaka anokwakheka okuntsonkothileyo kwaye aguquguquka ngokubanzi kwiiparamitha ezahlukeneyo, ngakumbi amanqanaba aphezulu eCa2+, Mg2+, Fe2+, Mn2+, SO42-, F, kunye neSiO2. Ukungaphumeleli ukususa kwangaphambili i-extractants ye-metal ephezulu ekhoyo kwi-membrane ye-osmosis engasemva kunokukhokelela kungcoliseko olunzulu lwe-inorganic.

Kumanzi amdaka asuka kwisityalo sentsimbi esiphantsi konyango lwesibini lwe-biochemical, i-aeration yenziwa okokuqala kwitanki ye-aeration ukuze i-oxidize i-Fe2 + ukuya kwi-Fe3 +. Ngaxeshanye, i-NaClO yongezwa ukunyusa umthamo we-Fe2+ oxidation kunye nokusebenza kakuhle kwe-bactericidal. Ubisi lwekalika longezwa ukulungelelanisa i-pH, ilandelwa yi-flocculation kunye ne-PAM kunye ne-PAC. I-Sedimentation, i-filtration esheshayo, kunye ne-activated carbon adsorption zisetyenziselwa ukususa izinto eziphilayo, i-chlorine eshiyekileyo, kunye ne-ion zentsimbi enzima. Ukulandela unyango lwe-UF, amanzi amdaka anyangwa nge-arhente yokunciphisa. I-Scale inhibitors kunye ne-asidi zingena kwinkqubo ye-RO.

2 Ukusetyenziswa kunyango lwamanzi amdaka e-refractory organic

Ukuprintwa kunye nokudaya amanzi amdaka kunye ne-petrochemical yokucocwa kwamanzi amdaka, ukuprintwa kunye nokudaya amanzi amdaka, ngaphezu kobuninzi bedayi, i-slurries, i-salts ye-inorganic, i-acids kunye ne-alkali, ineempawu ukuya kumaxesha angama-4000 umbala, umthamo omkhulu wamanzi, umxholo ophezulu wokungcola kwezinto eziphilayo, umgangatho wamanzi ohlukeneyo, njl njl. intlenga yenkunkuma, kunye nezingcolisi ikakhulu ziphuma ekuboleni kwenkunkuma kunye nokuvuza kwemvula. Umgangatho wamanzi untsonkothile, kwaye iCOD iphezulu kakhulu kunogutyulo lwasezidolophini. Ukongezelela, i-leachate iqulethe iindidi ze-ion zetsimbi, ezifana ne-Fe2+, i-Cd2+, i-Cr3+, i-Cu2+, i-Zn2+, kunye ne-concentration ye-Fe2 + ngexesha lenkqubo yokuvutshelwa.

Nangona inkqubo ye-A/O enezigaba ezibini yonyango lwe-biochemical isetyenziswe ngokubanzi ukuthotywa kwe-organic matter kunye ne-denitrification kwi-leachate yokulahla inkunkuma, ukusebenza kwamanzi amdaka akuzinzile. Ngoko ke, ngokusekelwe kwi-filtration yomatshini, ukusetyenziswa kwe-membrane ye-ultrafiltration kunye ne-A / O ukwenza inkqubo ye-MBR iphucule izinga lokususwa kwezinto eziphilayo kwi-leachate ye-landfill.

I-effluent, emva kokuhlukana kwe-sludge ngokusebenzisa i-membrane ye-ultrafiltration, ingena kwinkqubo ye-nanofiltration (NFN). I-NF inokwahlula ngokufanelekileyo izinto eziphilayo ezinobunzima be-molecular of 200m ukuya kwi-2000m kwaye ingasetyenziselwa ukwahlula into ethile yexabiso eliphezulu kumanzi avelisiweyo yi-MBR. Uphando lwenziwe kwiipropati ze-ion zetsimbi kunye ne-MBR + NF + RO yenkqubo yonyango edibeneyo ye-membrane emithathu. Iziphumo zibonisa ukuba inkqubo isebenza ngokufanelekileyo, kwaye nomgangatho wamanzi amdaka uyahlangabezana nemigangatho yolawulo longcoliseko lweendawo zokulahla inkunkuma eqinileyo kamasipala.

Ngexesha lokusebenza, ukuba amanzi amdaka e-NF ahlangabezana neemfuno zokukhutshelwa, anokukhutshwa ngokuthe ngqo. Ngaphandle koko, inokunyangwa ngakumbi ngokusebenzisa le nkqubo ye-RO ilandelayo. Uphando lwenkqubo ye-Ar/O-MBR+NF+RO yokunyanga i-leachate yokulahla inkunkuma ibonise ukuba ukongezwa kwekhabhoni esebenzayo kwi-reactor ye-A/O ayiphuculi nje kuphela ukususwa kwezinto eziphilayo kunye neentsimbi ezinzima kodwa kunciphisa ukungcoliswa kwe-membrane.

3 Ukusetyenziswa kunyango lokurisayikilisha olukumgangatho ophezulu

I-China ikwaseke izityalo ezinkulu zamanzi ezisetyenzisiweyo eBeijing, eTianjin, eHebei, eShandong nakwezinye iindawo. Phakathi kwazo, izikhululo ezininzi ezikhulu zokuphinda zisetyenziswe kwakhona zamanzi zisebenzisa inkqubo ye- "UF (MF) + RO" ephindwe kabini kwi-membrane ukunyanga iindidi ezimbini zogutyulo lwasezidolophini zibe kumanzi amdaka, zivelisa amanzi akumgangatho ophezulu aphinde asetyenziswe, asetyenziswa njengenxalenye yamanzi kwibhoyila yezityalo zamandla ashushu kwaye enye inxalenye isetyenziswa njengemilambo yomhlaba kunye namanzi ahlukeneyo asekhaya.

Iziko lokucocwa kwamanzi amdaka lengingqi lisebenzisa i-MBR edityaniswe ne-osmosis ebuyela umva ukunyanga amanzi amdaka kamasipala ukuze aphinde asetyenziswe. Amanzi afikelele kumanqanaba e-TOC

Ukuphucula ngokupheleleyo izibonelelo zetekhnoloji ye-osmosis ebuyela umva, ukunciphisa ukungcola kwe-membrane, kunye neendleko eziphantsi zokucocwa kwamanzi, inkampani yethu iphuhlise uthotho lweenkqubo ezidityanisiweyo ezilungiselelwe iimpawu zomgangatho wamanzi. Iindlela eziqhelekileyo zokunyanga amanzi, ezifana ne-coagulation kunye ne-sedimentation, i-high-concentration, kunye ne-high-efficiency filtration, ngokuqhelekileyo isetyenziselwa ukususa i-SS. I-NaClO, ubisi lwe-lime, kunye nezihlungi zesanti ze-manganese zisetyenziselwa ukunciphisa i-RO, i-manganese salts, i-calcium salts, kunye ne-silica salts kwi-influent Sargassum aeration kunye ne-oxidation system. I-O3 oxidation isetyenziselwa ukunyanga i-recalcitrant A/O organic matter. I-MBR, i-UF, kunye ne-NF zisetyenziselwa ukugcina i-SS efanelekileyo kunye ne-molecule encinci ye-organic. Ii-ion ze-high-valent zidityanisiwe kunye ne-UF + RO okanye i-MBR + RO iinkqubo ezimbini ze-membrane, okanye i-MBR + NF + RO ii-triple-membrane systems, iqinisekisa ukusebenza kwenkqubo ezinzileyo kunye nokuqinisekisa unyango lwe-RO lwamanzi amdaka e-organic recalcitrant.
