Ibitaro bitavuga bivuga umwanda wakozwe n'ibitaro birimo indwara z'ifarashi, ibyuma biremereye, amacakubiri, ibiti by'imikorere, ibiti, acide, na radiyoactivite. Ifite ibiranga kwanduza kwanduzwa, kwandura gukabije, no kwandura bidatinze. Hatabayeho kuvurwa neza, birashobora kuba inzira yingenzi yo gukwirakwiza indwara no kwanduza ikidukikije. Kubwibyo, kubaka Kuvura imyandaigihingwaMu bitaro byabaye urufunguzo rwo gukemura iki kibazo.
1.Gukusanya Ibitaro no Gutegura
Umushinga werekana imyanda yo murugo hamwe namazi yimvura atemba sisitemu, ihuye na sisitemu yo kuvoma imijyi. Imyanda yo mu buvuzi n'imyanya yo mu rugo mu gace k'ibitaro irakusanywa n'umuyoboro w'imiyoboro y'amazi, yateguwe na gahunda yo kuvura imyanda yashyinguwe (igishushanyo cya peteroli, hanyuma isohoka kuri sitasiyo yanduye. Nyuma yo kubona ibipimo by'ibihugu by'amazi byashyizwe ahagaragara mu bigo by'ubuvuzi, basohoka mu gihingwa cyo kuvura imivurungano mu mijyi binyuze mu muyoboro wa serwage.
Ibipimo nyamukuru byo gutunganya ibisobanuro byaKuvura imyandaigihingwa
① gride iringaniza ifite ibice bibiri bya gride nziza kandi nziza, hamwe nicyuho cya mm 30 hagati ya gri zibana na mm 10 hagati yinkoni nziza. Guhagarika ibice byinshi byahagaritswe nibikorwa byoroshye bikabije (nko guhagarika impapuro, imyenda, cyangwa ibisigazwa byibiribwa) kurinda ibikoresho byamazi no gutunganya ibipimo byagangiriye. Iyo ushyizwe, gukomera bigomba kuvamo 60 ° kuruhande rwumurongo utambitse wamazi kugirango byorohereze ibisigazwa byimibare. Kugirango wirinde imyanda hamwe no gutatanya ibintu byahagaritswe, igishushanyo gikwiye gukomeza igipimo cya sewage mbere na nyuma yo gukomeretsa hagati ya 0,6 m / s na 1.0 m. Ibintu byarushijeho kuba bafashe bigomba kwanduzwa mugihe cyo gukuraho kubera kuba hari umubare munini wa page.
② kugenzura pisine
HE kamere yibitero agena ireme ritaringaniye ryamazi yinjira muri sitasiyo yimyanda. Kubwibyo, ikigega cyo kugenzura gishyirwaho kugirango gikemure ireme nubwinshi bwimyanda no kugabanya ingaruka zingirakamaro mumitwaro yo kuvura nyuma. Muri icyo gihe, yashyizeho impanuka yo kurengana kuri pisine. Ibikoresho bya Aeation byashyizwe mu kigega cyo kugenzura kugirango birinde imyanda ihagaritswe kandi itezimbere biodegrafiya y'amazi.
Pool ya hypoxic aerobic
Ikigega cya Anoxic Aerobic nigikorwa cyibanze cyo kuvura imyanda. Inyungu zayo ni uko usibye umwanda kama Zana, ifite kandi imikorere runaka ya azote na fosifore. Inzira ya A / o ihuza igice cyimbere hamwe nigice cyinyuma inyuma, hamwe nigice kitarenze 0.2 MG / L na O na O.2 MG / L.
Mu cyiciro cya Banoxic, bagiteri ya acteric hydrolyze yahagaritse imyanya ihumanya, fibre, hamwe no gukosora kamere mu madari ya kama, bigatuma ibinyabuzima bifatika mu mahame kama, bigatuma ibinyabuzima bya macrommolecular byo kubora molecule kama. Ibikorwa bya Organic bihindurwa mubibazo byoherejwe. Iyo ibikomoka kuri hydrobic hydrobic binjire muri tank ya aerobic kubikoresho bya Aerobic, biodegradudable yimyanda iratera imbere kandi imikorere ya ogisijeni iratera imbere.
Mu gice cya abakoxic, bagiteri ya heterotroprofic Abamoni n'Abapfumu nka Proteine n'ibinure (n ku murongo wa kama cyangwa aside amine muri aside amino (NH3, NH4 +). Mu bihe bihagije bya ogisijeni, nitrification ya bagiteri ya bagiteri ya autotroproicique nh3-n (NH4 +) kugeza No3 -, hanyuma isubiye kuri pisine binyuze mu butegetsi. Munsi y'agaciro, guhakana bagiteri ya heterotrophic bigabanya no3 - kuri azote ya molekani (n, na o mubidukikije kandi nkavura nabi.
TANK
Akayunguruzo effluent yinjira muri ikigega cyo kwanduza gahunda yo gukomeza igihe runaka hagati yimyanda no ku byangiza, kureba ko kwanduza neza bacateri mu mazi. Effuent isohoka mumurongo wa komini. Dukurikije "Gusohora amazi ku bigo by'ubuvuzi", igihe cyo gukemura amaso ku bitaro byanduye byanduza ntigishobora kuba munsi y'amasaha 1.5, kandi igihe cyo kubanjiriza imyanda mu bitaro byuzuye ntibigomba kuba munsi y'isaha 1.0.
