Gusaba Ingaruka ya PAC mu kuvura amazi ku ruganda rw'amashanyarazi

1. Mbere yo kuvura amazi meza

Umubiri w'amazi usanzwe ukubiyemo ibyondo, ibumba, humus nibindi byahagaritswe na bagiteri, vingi, virusi hamwe nindi mishinga mikoro, niyo mpamvu nyamukuru itera amazi, ibara nimpumuro. Ibi bintu birenze urugero byinjira muri ion-guhanahana, kwanduza ibisibo, gabanya ubushobozi bwa resin, ndetse bikagira ingaruka kumiterere yubusa bwa sisitemu yo gushushanya. Guhangana, gukosora no kuvura no kuvura nukugabanya umwanda nkintego nyamukuru, kugirango ibizwe nibibazo byamazi bigabanutse kugera munsi ya 5mg / l, kugirango bisobanuke amazi. Ibi byitwa kwanga amazi. Nyuma yo kwitegura, amazi arashobora gukoreshwa nkamazi ya boiler gusa mugihe umunyu washenze mumazi uvanwaho na ion, imyuka yashongeshejwe mumazi akurwaho no gukubitwa cyangwa guhubuka cyangwa kuvuza. Niba ibyo byanduye bitakurwaho mbere, gukurikiranwa (guhatanira) ntibishobora gukorwa. Kubwibyo, kuvura amazi ni ihuriro ryingenzi muburyo bwo kuvura amazi.

Inzira yo Gutegura Imbaraga zubushyuhe niyi ikurikira: amazi mbisi → coagelationtation → imvura kandi ibisobanuro → Filtration. Coagulant ikoreshwa muburyo bwo gutura ni chlfalumum chloride, polyfelric sulfate, sulmunum suriploride, erric trichlogide, nibindi bikurikira bitangiza ahanini na chloride ya polyimininum.

Polyilumum chloride, ivugwa nka PAC, ishingiye ku myambarire ya aluminium nk'ibikoresho fatizo, ku bushyuhe bwinshi hamwe na polymer na gahunda y'ibisaruro biba bitandukanye, ibisobanuro byakazi ntabwo ari bimwe. Inzira ya MoleCure ya PAC [AL2 (OH) NCI6-N] m, aho n irashobora kuba integer iri hagati ya 1 na 5, na m ni integer ya cluster 10. PAC iza muburyo bukomeye kandi bwamazi.

Uburyo bwo gukora

Hariho ingaruka eshatu zingenzi za coagulants ku bice bya colloidal mumazi: Kubogamiye amashanyarazi, adsorplisation yo kurakara no gukomera. Muri iyi ngaruka eshatu nimwe nyamukuru biterwa n'ubwoko no kwishyura coagulant, imiterere n'ibirimo by'ibice bya colloidal mu mazi, na pH agaciro ka PH. Uburyo bw'ibikorwa bya polyiminum isa n'iya sulfate ya aluminiyumu, kandi imyitwarire ya aluminiyumu mu mazi yerekeza ku nzira ya Al3 + itanga ubwoko butandukanye bwa Hydroleyed.

POLYOUMUNUM CHLORIDE irashobora gufatwa nkibicuruzwa bitandukanye bitandukanya muburyo bwa hydrolysis na poly umubare wa aluminiyumu muri al (OH) mubihe bimwe. Irerekana mu buryo butaziguye mu mazi mu buryo butandukanye bw'ubwoko butandukanye bwa polymeric na A1 (OH) a (s), nta modoka ya hydrolysis ya al3 +.

3. Gusaba no guhindura ibintu

1. Ubushyuhe bwamazi

Ubushyuhe bw'amazi bufite uruhare rugaragara ku ngaruka zo kuvura. Iyo ubushyuhe bw'amazi ari buke, hydrolysis ya coagulant iragoye, cyane cyane iyo ubushyuhe bw'amazi ari munsi ya 5 ℃, umubare w'amazi utinda, kandi ikirambo cyakozwe gifite imiterere, amazi menshi. Iyo ubushyuhe bw'amazi ari buke, gukemura ibice bya colloidal byongerewe, igihe cya floctulation ni kirekire, kandi igipimo cyo kwizihiza kiratinda. Ubushakashatsi bwerekana ko ubushyuhe bwamazi bwa 25 ~ 30 ℃ bukwiye.

2. PH agaciro k'amazi

Inzira ya hydrolyse ya chlolumum chloride nigikorwa cyo gusohora h +. Kubwibyo, mubihe bitandukanye PH, hazabaho hydrolysis itandukanye, kandi agaciro ka PH cyiza cya chlloumum kuvurwa na pogulation ya chlolumum muri rusange hagati ya 6.5 na 7.5. Ingaruka yo gutura iri hejuru muri iki gihe.

3. Dosage ya coagulant

Iyo umubare wa coagulant wongeyeho ntabwo uhagije, ubwicanyi busigaye mumazi yo gusohoka ari manini. Iyo amafaranga ari manini cyane, kuberako ibice bya colloidal mumazi adsorb coagulant nyinshi, imitungo ishyuza yintera ya colloidal irahinduka, bikavamo imvururu zisigaye zongeye kwiyongera. Inzira yo gutura ntabwo ari ibintu byoroshye, bityo ibipimo bisabwa ntibishobora kugenwa hakurikijwe kubara, ariko bigomba kugenwa hakurikijwe ubuziranenge bwamazi kugirango umenye dosage ikwiye; Iyo impinduka zubwiza hagati, dosage igomba guhinduka ukurikije.

4. Twandikire Hagati

Muburyo bwo kwivuza cyangwa ubundi buryo bwo kwivuza, niba hari umubare wibyondo mu mazi, ingaruka zo kwivuza zirashobora kunozwa cyane. Irashobora gutanga ubuso bunini, binyuze muri adsorption, catalise na Crystalisation Core, kunoza ingaruka zo kuvura.

Imvura yo kwigunga ni uburyo bukoreshwa cyane bwo gutunganya amazi kuri ubu. Inganda za Polyiminum zikoreshwa nkumubiri wamazi, hamwe nibikorwa byiza bya coagulant, Floc nini, Imvura Yinshi, Imvura Yinshi, Urwego Rukomeye, Ugereranije na Flocculant Guhuzwa nibikorwa byungurura akayunguruzo ka Varbon Akayunguruzo, uhindagurika amazi mbisi, ubwiza bwa sisitemu ya dealt nayo bwiyongereye, kandi igiciro cyimikorere kiragabanuka, kandi igiciro cyimikorere kiragabanuka.
