Gushyira mu bikorwa imikorere ihanitse ya osmose membrane mu gutunganya imyanda

RO membrane yo gutandukanya tekinoroji

Ikoreshwa rya tekinoroji ya RO ikoresha itandukaniro ryumuvuduko uhagaze muribwo buryo bwo gutwara. Molekile ntoya, nka molekile zamazi, zitsinda umuvuduko wa osmotic kugirango unyure muri RO membrane, bityo ubatandukanya numwanda. Umuvuduko wimikorere muri rusange uri hagati ya 1.5 na 10.5 MPa, kandi sisitemu irashobora kugumana molekile nto ya 1 kugeza 10A.

Mu gutunganya amazi, RO, nk'ibikoresho by'ingenzi, irashobora gukuraho ibice birenga 97% by'ibinyabuzima bitangirika, 99% by'ibinyabuzima bifite uburemere bugereranije bwa 300 cyangwa birenga, hejuru ya 99% by'ibice bitandukanye birimo na bagiteri, na 95% bya SiO2 mu mazi.

Agace kanini gakoreshwa murugo muguhindura osmose membrane ikomeza kuba amazi manini yo kugaburira amazi, agakurikirwa namazi meza yinganda n’amasoko y’amazi yo kunywa. Porogaramu ya Membrane nayo yageze ku ntera igaragara mu bikoresho bya elegitoroniki, igice cya kabiri, imiti, ubuvuzi, ibiryo, ibinyobwa, inzoga, imiti, kurengera ibidukikije, metallurgie, n’inganda z’imyenda. Ibizakenerwa mu gihe kizaza harimo gutunganya amazi mabi yo gukonjesha amashanyarazi, amazi manini manini yo mu nyanja, kuvanaho amazi meza, hamwe no gutunganya amazi mabi y’amakomine n’inganda.

Gukoresha RO membrane mugutunganya imyanda

. Ibigize ibinyabuzima bya SS birimo umubare munini wa Ca2 + Mg2 + K +, Cl-, SO42-, HCO3 na HCO3- ntibiri munsi ya 1.5 mg / L. Ahantu hacukurwa amabuye y’ibura ry’amazi, hifashishijwe ikoreshwa rya tekinoroji ya osmose mu gutunganya cyane umusaruro n’amazi yo mu rugo byatejwe imbere.

Gukoresha amazi yubutare nkibikoresho byo kwitegura, flocculation, ubutayu, hamwe no kuyungurura byihuse byongeweho kugirango bikureho SSS nyinshi mumazi, bivamo ihinduka rya osmose ihindagurika ryinjira munsi ya 1 NTU. Nyuma yo kuvura osose ihindagurika, igipimo cyo kuvanaho imyanda cyegereye 100%, hamwe n’ikigereranyo cya 96%.

(2) Gutunganya amazi yimyanda

Inganda z’ibyuma, zikoresha umutungo cyane, zikoresha amazi menshi kandi zangiza cyane, zingana na 14% by’ubushinwa bukoresha amazi. Amazi mabi yinganda zikoreshwa cyane mubikorwa byinganda. Amazi mabi afite ibice bigoye kandi bihindagurika cyane mubice bitandukanye, cyane cyane urwego rwo hejuru rwa Ca2 +, Mg2 +, Fe2 +, Mn2 +, SO42-, F, na SiO2. Kunanirwa gukuramo mbere ibyuma bivamo ibyuma byinshi biri hejuru ya osmose ihindagurika bishobora gutera umwanda udasanzwe.

Ku mazi y’amazi ava mu ruganda rukora ibyuma bivura ibinyabuzima bya kabiri, aeration ikorwa bwa mbere mu kigega cya aeration kugirango oxyde Fe2 + kugeza kuri Fe3 +. Icyarimwe, NaClO yongeweho kugirango yongere ubushobozi bwa Fe2 + okiside hamwe na bactericidal efficacy. Amata ya lime yongeweho kugirango ahindure pH, agakurikirwa na flocculation hamwe na PAM na PAC. Kwikuramo, kuyungurura byihuse, hamwe na carbone adsorption ikoreshwa noneho mugukuraho ibintu kama, chlorine isigaye, hamwe nicyuma gikomeye. Nyuma yo kuvura UF, imyanda ivurwa hamwe na agent igabanya. Inzitizi zingana na aside byinjira muri sisitemu ya RO.

2 Gushyira mugikorwa cyo gutunganya amazi mabi yangiritse

Gucapa no gusiga amazi y’amazi hamwe no gutunganya amazi y’amazi ya peteroli, gutunganya no gusiga amazi y’amazi, usibye amarangi menshi, amarangi, imyunyu ngugu, acide na alkalis, bifite ibimenyetso biranga inshuro zigera ku 4000 ibara, ubwinshi bw’amazi, ibintu byinshi byangiza imyanda ihumanya, imyanda mibi ituruka ku myanda ihumanya imyanda iva mu myanda iva mu myanda iva mu myanda iva mu myanda. biva muri mikorobe yangirika yimyanda no kugwa imvura. Ubwiza bwamazi buragoye, kandi COD irarenze cyane iy'imyanda yo mumijyi. Mubyongeyeho, leachate irimo kandi ion zitandukanye zicyuma, nka Fe2 +, Cd2 +, Cr3 +, Cu2 +, Zn2 +, hamwe na Fe2 + yibanze mugihe cya fermentation.

Nubwo A / O ibyiciro bibiri byo kuvura ibinyabuzima byakoreshejwe cyane mu kwangiza ibintu kama no gutesha agaciro imyanda iva mu myanda, imikorere y’amazi ntabwo ihagaze. Kubwibyo, hashingiwe ku kuyungurura imashini, gukoresha ultrafiltration membrane na A / O kugirango habeho inzira ya MBR byazamuye igipimo cyo kuvanaho ibintu kama mumyanda.

Amazi, nyuma yo gutandukana kwa silige binyuze muri ultrafiltration membrane, yinjira muri sisitemu ya nanofiltration (NFN). NF irashobora gutandukanya neza ibinyabuzima bifite uburemere bwa 200m kugeza 2000m kandi birashobora no gukoreshwa mugutandukanya ibintu bimwe na bimwe bifite agaciro kanini n’amazi yakozwe na MBR. Ubushakashatsi bwakozwe ku miterere ya ion ion hamwe na MBR + NF + RO uburyo butatu bwo kuvura. Ibisubizo byerekana ko inzira ikora neza, kandi ubuziranenge bw’amazi bwujuje ubuziranenge bwo kurwanya umwanda ku myanda y’imyanda ikomeye.

Mugihe gikora, niba imyanda ya NF yujuje ibyangombwa bisohoka, irashobora gusohoka muburyo butaziguye. Bitabaye ibyo, irashobora kuvurwa hakoreshejwe sisitemu ya RO ikurikira. Ubushakashatsi bwakozwe kuri gahunda ya Ar / O-MBR + NF + RO yo kuvura imyanda y’imyanda bwerekanye ko kongeramo karubone ikora kuri reaction ya A / O bidatezimbere gusa uburyo bwo kuvanaho ibintu kama n’ibintu biremereye ahubwo binagabanya kwanduza membrane.

Ubushinwa kandi bwashyizeho ibihingwa binini by’amazi bitunganyirizwa mu mujyi wa Beijing, Tianjin, Hebei, Shandong n'ahandi. Muri byo, sitasiyo nini nini zogusubiramo amazi zikoresha "UF (MF) + RO" inzira ebyiri zo gutunganya uburyo bwo gutunganya ubwoko bubiri bw’imyanda yo mu mijyi mu mazi mabi, ikabyara amazi meza yo mu rwego rwo hejuru, akoreshwa mu gice cy’amazi y’amashanyarazi y’amashyanyarazi naho ikindi gice akoreshwa nkinzuzi nyaburanga n’amazi atandukanye yo mu ngo.

Uruganda rutunganya amazi y’amazi rukoresha MBR ihujwe na osmose ihindagurika mu gutunganya amazi y’amazi yo muri komine kugirango yongere akoreshwe. Amazi yageze kurwego rwa TOC

Kugirango dukoreshe neza ibyiza bya tekinoroji ya osmose, kugabanya kwanduza membrane, no kugabanya amafaranga yo gutunganya amazi, isosiyete yacu yashyizeho urutonde rwibikorwa bihujwe bijyanye nubuziranenge bwamazi. Uburyo bwa gakondo bwo gutunganya amazi, nka coagulation hamwe nubutayu, kwibanda cyane, hamwe no kuyungurura cyane, bikoreshwa mugukuraho SS. NaClO, amata y'indimu, hamwe na filteri ya manganese ikoreshwa mu kugabanya RO, umunyu wa manganese, umunyu wa calcium, hamwe n'umunyu wa silika muri sisitemu ikomeye ya Sargassum aeration na okiside. O3 okiside ikoreshwa mugutunganya ibintu bya A / O byongeye. MBR, UF, na NF bikoreshwa mukugumana SS nziza na molekile ntoya. Iyoni zifite agaciro gakomeye zahujwe na UF + RO cyangwa MBR + RO sisitemu ebyiri-ya membrane, cyangwa na MBR + NF + RO ya triple-membrane sisitemu, ikora neza kandi igafasha RO gutunganya amazi mabi yangiza.

Ibyifuzo bya sosiyete

"HID Membrane" yibanda ku ikoranabuhanga ryo gutandukanya membrane no guteza imbere ibicuruzwa bya membrane, guha abakiriya itandukaniro ry’amazi yabigize umwuga, ibisubizo byibanda kuri membrane hamwe nibikoresho byuzuye bya sisitemu kuva mubikorwa bya membrane, gukora ubushakashatsi no guteza imbere, kugisha inama imishinga, guhuza sisitemu na serivisi za tekinike ihuriweho.

Ikirangantego cyiyemeje gukoresha ikoranabuhanga ryo gutunganya amazi mabi yinganda hamwe nibisabwa nibicuruzwa mumyaka irenga 16. Yabanjirije iyambere kwisi mubice byinshi byifashishwa bya revers osmose membrane, ikusanya uburambe bukoreshwa mubisabwa, kandi ibona patenti nyinshi zavumbuwe hamwe na patenti yicyitegererezo mubikorwa bifitanye isano, byuzuza icyuho kinini murugo no mumahanga, kandi gifite izina ryinshi mubikorwa.
