Kuki amazi mabi yumunyu mwinshi kuyagora? Tugomba mbere na mbere gusobanukirwa n’amazi mabi yumunyu mwinshi ningaruka zamazi yumunyu mwinshi kuri sisitemu ya biohimiki! Iyi ngingo ivuga gusa ku gutunganya ibinyabuzima byamazi yumunyu mwinshi!
1. Amazi yumunyu mwinshi ni iki?
Amazi yumunyu mwinshi bivuga amazi mabi arimo umunyu byibuze byibuze 1% (bihwanye na 10,000mg / L). Bituruka ahanini ku bimera byimiti no gukusanya no gutunganya amavuta na gaze gasanzwe. Aya mazi mabi arimo ibintu bitandukanye (harimo umunyu, amavuta, ibyuma biremereye hamwe nibikoresho bya radio). Amazi yumunyu akorwa hifashishijwe amasoko menshi, kandi amazi yiyongera uko umwaka utashye. Kurandura imyanda ihumanya mumazi yumunyu bigira ingaruka zikomeye kubidukikije. Uburyo bwibinyabuzima bukoreshwa mukuvura. Ibintu byumunyu mwinshi cyane bigira ingaruka mbi kuri mikorobe. Uburyo bwa fiziki na chimique bukoreshwa mukuvura, busaba ishoramari rinini nigiciro kinini cyo gukora, kandi biragoye kugera ku ngaruka ziteganijwe zo kwezwa. Gukoresha uburyo bwibinyabuzima bwo gutunganya ayo mazi mabi biracyibandwaho mubushakashatsi murugo ndetse no hanze yarwo.
Ubwoko nibintu bya chimique yibintu kama mumazi mabi yumunyu mwinshi biratandukana cyane bitewe nibikorwa byakozwe, ariko imyunyu irimo ni imyunyu nka Cl-, SO42-, Na +, Ca2 +. Nubwo iyi ion ari intungamubiri zingenzi kugirango imikurire ya mikorobe ikure, igira uruhare runini mugutezimbere reaction yimisemburo, kugumana imiterere ya membrane no kugenzura umuvuduko wa osmotic mugihe cyo gukura kwa mikorobe. Ariko, niba kwibumbira hamwe kwa ion ari hejuru cyane, bizagira ingaruka mbi kandi zifite ubumara kuri mikorobe. Ikigaragara nyamukuru ni: kwibanda cyane k'umunyu, umuvuduko mwinshi wa osmotic, umwuma wa selile mikorobe, bigatuma protoplasme itandukana; umunyu ugabanya ibikorwa bya dehydrogenase; ion nyinshi za chloride Bakteri ni uburozi; umunyu mwinshi ni mwinshi, ubwinshi bwamazi y’amazi ariyongera, kandi umwanda ukoreshwa ureremba byoroshye kandi biratakara, bityo bikagira ingaruka zikomeye kubikorwa byo kweza ibinyabuzima.

Iyo umunyu uri munsi ya 2g / L, umwanda wumunyu urashobora gutunganywa murugo. Mugukomeza buhoro buhoro umunyu wamazi yo kugaburira ibinyabuzima, mikorobe izaringaniza umuvuduko wa osmotic uri mu ngirabuzimafatizo cyangwa irinde protoplazme mu ngirabuzimafatizo binyuze mu buryo bwihariye bwo kugenzura umuvuduko wa osmotic. Ubu buryo bwo kugenzura bukubiyemo kwegeranya ibintu bifite uburemere buke bwa molekile kugirango bibe urwego rushya rurinda umubiri kandi rwigenga. Inzira ya metabolike, impinduka mubigize genetike, nibindi.
Kubwibyo, isuka isanzwe ikora irashobora gutunganya amazi yumunyu mwinshi murwego runaka rwumunyu mwinshi binyuze murugo mugihe runaka. Nubwo isuka ikora irashobora kongera uburyo bwo kwihanganira umunyu muri sisitemu no kunoza uburyo bwo kuvura sisitemu binyuze mu gutunga urugo, gutunga ibimera bikora Microorganisme bifite ubushobozi buke bwo kwihanganira umunyu kandi byumva impinduka z’ibidukikije. Iyo ibidukikije bya chloride bihindutse bitunguranye, guhuza n'imiterere mikorobe bizahita bishira. Gutunga urugo ni ihinduka ryigihe gito ryimiterere ya mikorobe kugirango ihuze nibidukikije kandi nta biranga genetike. Uku guhuza n'imihindagurikire y'ikirere byangiza cyane gutunganya imyanda.
Igihe cyo kumenyekanisha sludge ikora ni iminsi 7-10. Kumenyekanisha birashobora kunoza kwihanganira mikorobe mvaruganda kumunyu mwinshi. Kugabanuka kwimyanda ikora cyane mugihe cyambere cyo kumenyekana biterwa nubwiyongere bwumuti wumunyu wangiza mikorobe kandi bigatera urupfu rwa mikorobe zimwe. Yerekana gukura nabi. Mu cyiciro cya nyuma cyo gutura mu rugo, ibinyabuzima bito byahinduye ibidukikije byahindutse bitangira kubyara, bityo kwibumbira hamwe kwa siliveri ikora biriyongera. GufataKODukoresheje siliveri ikora muri 1.5% na 2,5% ya sodium ya chloride yumuti nkurugero, igipimo cyo gukuraho COD mugihe cyambere na nyuma yo kumenyekana ni: 60%, 80% na 40%, 60%.
2. Koresha amazi
Kugirango ugabanye ubukana bwumunyu muri sisitemu ya biohimiki, amazi yinjira arashobora kuvangwa kuburyo umunyu uri munsi yumubare w’uburozi, kandi kuvura ibinyabuzima ntibizabuzwa. Inyungu zayo nuko uburyo bworoshye kandi bworoshye gukora no gucunga; ibibi byayo nuko byongera igipimo cyo gutunganya, ishoramari ryibikorwa remezo nigiciro cyo gukora. ?
3. Hitamo bagiteri yihanganira umunyu
Bagiteri ya Halotolerant ni ijambo rusange kuri bagiteri zishobora kwihanganira umunyu mwinshi. Mu nganda, ahanini ni inshingano ziteganijwe kugenzurwa no gukungahazwa. Kugeza ubu, umunyu mwinshi urashobora kwihanganira hafi 5% kandi urashobora gukora neza. Ifatwa kandi ubwoko bwamazi yumunyu mwinshi. Uburyo bwa biohimiki yo kuvura!
4. Hitamo inzira yumvikana
Uburyo butandukanye bwo kuvura bwatoranijwe kubintu bitandukanye bya chloride ion, kandi inzira ya anaerobic yatoranijwe neza kugirango igabanye kwihanganira urugero rwa chloride ion yibice bya aerobic. ?
Iyo umunyu urenze 5g / L, guhumeka no kwibanda kubunyunyu nuburyo bwiza bwubukungu kandi bwiza. Ubundi buryo, nkuburyo bwo guhinga bagiteri irimo umunyu, bifite ibibazo bigoye gukora mubikorwa byinganda.
Isosiyete ya Lianhua irashobora gutanga isesengura ryihuse rya COD kugirango isuzume amazi mabi yumunyu kuko reagent ya chimique irashobora gukingira ibihumbi icumi bya chloride ion.
