Floculantinowanzonzi se "maindasitiri panacea", iyo ine huwandu hwakawanda hwekushandisa. Senzira yekusimbisa kupatsanurwa-kwemvura kusimba mumunda wemvura kurapwa kwemvura, inogona kushandiswa kusimbisa iyo yekutanga chaiyo yegungwa, kuronga kwekurapa uye sekondari yekuputika mushure mekushandurwa kwakashandurwa SLUDGE nzira. Inogona zvakare kushandiswa kurapwa kwetertiary kana kurapwa kwepamberi kwegungwa. Mukurapwa kwemvura, pane dzimwe nguva zvinhu zvinokanganisa mari yemari
1. Kufurira kwekushisa kwemvura
Tembiricha yemvura ine kukosha kwakanyanya pane zvinodhaka zvekushandisa, uye yakaderera tembiricha mvura munguva yechando
Ine simba rakakura pane zvinodhaka zvekushandisa zvinodhaka, izvo zvinowanzotungamira pakuumbwa zvishoma nezvishoma kwe falls neakanaka uye zvakasununguka zvimedu. Zvikonzero zvikuru ndezvekuti:
Iyo hydrolysis yemhando yemasoritulanti yemunyu ndeyekupedzisira kuita, uye hydrolysis yekudzikiswa kwemazwi emvura akaoma.
Iyo viscosity yemvura yakaderera-tembiricha yakakura, inokonetesa iyo brownian yekufambisa yekusvitswazve mitezo mukati
Mvura uye inoderedza mukana wekurovera, izvo zvisiri kubereka kuSefablization uye kusunganidzwa kwemakonzo uye kunokanganisa kukura kwehombodo.
Kana tembiricha yemvura payakadzika, hydration yezvikamu zvemvura zvinowedzerwa, izvo zvinotadzisa kubatana kwezvikamu zve cocolidal, uye zvakare zvinokanganisa kusimba pakati peiyo colloid.
Iyo tembiricha yemvura ine chekuita nePH yemvura. Kana tembiricha yemvura ichinge yakaderera, iyo pfi kukosha kwemvura inowedzera, uye inoenderana ph kukosha yakanakira yekodhi ichawedzerawo. Naizvozvo, munguva yechando mumatunhu anotonhora, zvakaoma kuwana kabhuku kaakawana mukana kunyange kana huwandu hwakawanda hwecaluulant hwakawedzerwa.
2. PH uye Alkalinity
Iko kukosha pH kukosha kwechiratidzo chekuti mvura iri acidic kana alkaline, ndiko kuti, chiratidzo cheH + Continternation mumvura. Iyo PH Kukosha kweiyo mbichana mvura inokanganisa zvakananga neHydrolyis kuita, ndiko kuti, kana iyo phengo yemvura yemvura iri mukati meimwe huwandu, mari yekubhadhara inogona kuvimbiswa.
Kana kosi yacho ichiwedzerwa kumvura, iyo hi + yekuvhara mumvura inowedzera nekuda kweiyo hydrolysis yekubatira, iyo inokonzera kukosha kwemvura kuti idonhedze uye inotadzisa hydrolysis. Kuti uchengetedze iyo pH mukati meiyo yakakwana renji, mvura yacho inofanira kuve nezvakakwana zveAlkaline zvinhu zvekusatadzisa H +. Mvura yakasikwa ine imwe nhanho yeAlkalinity (kazhinji hco3-), iyo inogona kumutsidzira iyo HI + yakagadzirwa panguva yehydrolysis yeCogulant, uye ine midziyo yeiyo ph kukosha ph. Kana iyo alkalinity yemvura yakaomeswa isina kukwana kana iyo kosi inowedzerwa zvakawandisa, iyo pfi kukosha kwemvura inodonha zvakanyanya, kuparadza mari yemari.
3. Kufurira kwechimiro uye kusvinura kwekusvibiswa mumvura
Iyo size size uye chaunoita chamupasi kweSS mumvura inokanganisa mari yemari. Kazhinji, kuiswa kwezvinhu zvidiki zvidiki uye yunifomu, uye mari yemhedzisiro iri murombo; Iko kusvinura kwemvura mumvura kwakaderera, uye mukana wekukanganiswa kwezvinhu zvidiki, izvo zvisina kunaka zvekubatikana; Kana tarisiro yakakura, kuitira kuti isimbise iyo collid mumvura, iyo yekudhirowa inodiwa inowedzera kwazvo. Kana huwandu hukuru hwenjenya riripo mumvura, zvinogona kushatirwa nezvimedu zvemvura, nekudaro zvichichinja hunhu hwepakutanga hwepamhepo, zvichiita kuti zvimedu zvocolidalidal zvakanyatsogadzikana, izvo zvinokanganisa zvakanyanya coaglation. Panguva ino, oxidant inofanira kuwedzerwa kumvura kuti iparadze mhedzisiro yeiyo organic nyaya, kuvandudza mari yekubatanidzwa.
Yakanyungudika munyu mumvura inogona zvakare kubata iyo coagulation mhedzisiro. Semuenzaniso, apo huwandu hwakawanda hwe calcium uye magnesium ion zviripo mumvura yakasikwa, inokodzera kugoverana, nepo huwandu hwakawanda hweCl- hachiitike kucomputer. Munguva yemwaka wemafashama, mvura yakakwira yemvura ine huwandu hwakawanda humus inopinda muchirimwa nekuda kwekunzwa kwemvura yekunaya, uye pre-chlorination uye dosagant mhou kazhinji inoshandiswa pane izvi.
4. Simba rekunze kwemvura kuchengetedza mamiriro
Mamiriro ezvinhu ekutanga ekuunganidzwa kweiyo collodal temple ndeyekuparadza iyo collodal zvimedu, uye kuita kuti isimbe colidal colidal colidel zvinoenderana nemumwe nemumwe. Basa guru reCoagulant ndeyekuita kuti ubudise iyo collodal maseru, uye yekunyepedzera kwekunze ndeyekuti iyo collodal conculs inogona kunyatsobata mari yacho, kuitira kuti iyo colloid svina kuti ubate mumwe nemumwe kuti aumbe flocs.
Kuti uite kuti chidimbu chidimbu chidimbu chiwedzere kuwirirana nekonzo, zvinoitika zvinobva zvanyatsovharirwa mumvura, zvinowanzozivikanwa sekukurumidza kusanganisa, izvo zvinodikanwa mukati memakore gumi kusvika makumi matatu uye zvisingasviki maminitsi maviri zvakanyanya.
5. Kufurira kwemvura kukanganisa kwemvura
Kuvhunduka kwemvura kunoreva kune nguva nenguva Iyo yemvura yemuguta yekushandisa yemvura uye kugadziridzwa kwemvura yakawanda inokanganisa mvura iri muzhizha muZhizha Uye iyo yemvura mhedzisiro mushure mekunyura haina kunaka kwazvo. Izvo zvakakosha kucherechedza kuti shanduko iyi haiwedzere mutsara. Mushure meizvozvo, teerera kuchengeta iyo alum mune reaction tangi, kuti irege kuparadza mari yemhedzisiro nekuda kweiyo yakawandisa dosage.
6. FloculantKuponesa matanho
Kuwedzera kune zvinhu zviri pamusoro apa, kune mamwe matanho anoponesa zvinodhaka, sekuwedzera huwandu hwezvinodhaka, zvakadai sekusimbisa kwedziva remvura, kudzikisira mishonga yemishonga, kusimbisa mushonga, uye kuchengetedza zvinodhaka.
Kana Polyacrylwide anoda kuchengetedza mitengo mukushandisa, inodikanwa kusarudza yakakodzera muenzaniso. Iyo nheyo ndeyekusarudza iyo polwacrylamide neyakanakisa kurapwa, iyo inodhura haisi iyo yakanyanya kunaka, uye usayedze kuve yakachipa kukonzera kurapa kwemarara kurapwa, asi kuwedzera mutengo. Sarudza mumiririri asiri kungoderedza zvinyoro-nyoro zvechinyakare, asi zvakare anoderedza dosage yeiyo unit mumiririri. Ita flccess miedzo pane yakapihwa mishonga samples, sarudza marudzi maviri kana matatu emishonga ine mishonga yakanaka yekuedza, uye wozoita muyedzo wekuedza zvichiteedzana kuti ucherechedze madhiri ekupedzisira uye sarudza iyo yekupedzisira mishonga yemishonga.
Polwandacrrylambide kazhinji kazhinji yakasimba masisitimu. Inoda kuve yakagadzirirwa mumhedzisiro yekugadzirisa neimwe nzira yekunyora. Iyo yekuvhara inowanzoitika pakati pe1.1% uye 0.3%. Kunyanya kutariswa kana kutetepa zvakanyanya kuchakanganisa mhedzisiro, kutambisa mushonga, wobva wawedzera mutengo, uye unyungudutsire polnerarular polmerization. Mvura yechinhu inofanira kunge yakachena (senge yemvura yemapepa), kwete sewage. Mvura pakamhembe tembiricha yakaringana, kazhinji hapana kupisa kunodiwa. Kana tembiricha yemvura ikave yakaderera kupfuura 5 ° C, kushungurudzika kunononoka, uye kumhanya kwekunyungudika kunowedzera kana tembiricha yemvura ichinge ichiwedzera. Asi pamusoro makumi mana Kazhinji, mvura tap yakakodzera kugadzirira polymer mhinduro. Yakasimba acid, alkali yakasimba, mvura yakakwirira yemunyu haina kukodzera kugadzirira.
Teerera kune iyo yekurapa nguva mukugadziriswa kwemumiririri, kuti mumiririri anogona kunyungudika mumvura uye asingaunganidzwe, zvimwe haingangoita kuti marara, asi zvakare kukanganisa mhedzisiro yechidhiro. Iro jira refaira uye pombi dzinogarwawo kuti dzibvisirwe, zvichikonzera marara akadzokororwa. Kamwe yakaumbwa mune mhinduro, nguva yekuchengetedza ishoma. Kazhinji kutaura, kana mhinduro yekugadzirisa iri 0,1%, iyo isiri-anonic polymer mhinduro isingafanire kupfuura vhiki imwe, uye iyo cationric polymer mhinduro haifanire kupfuura rimwe zuva.
Mushure mekugadziriswa kwemumiririri, panguva yekuita dhizaini, teerera shanduko yemhando yemhando uye mhedzisiro yemadhaka, uye gadzirisa iyo madhiri enguva yekuzadzisa iri nani dingi.
Mushonga unofanira kuchengetwa munzvimbo yakaoma yekuchengetedza, uye bhegi remishonga rinofanira kusungwa. Mukushandisa, shandisa zvakawandisa sezvinobvira, uye chisimbiso iyo isina kushandiswa mushonga kuti udzivise kunyorova. Mukugadzirira kweMishonga, Kuchengeta kunofanirwa kutorwa kusatorwa zvakanyanya sezvinobvira, uye zvinwiwa zvakaiswa kwenguva yakareba zviri nyore hydrolyzed uye haichazoshandiswa.
Well-rune midziyo, nyanzvi yemari vashandi, uye zviri nani mushure mekutengesa masevhisi; Isu tiriwo mhuri yakakura, chero munhu anogara nesangano rakakosha "kubatana, kutsungirira, kushivirira" kwemitsetsePolwandacrrylambideFlocculelamide Anonic Cationic mvura yekurapa Polyacrylamide
Quols yeChina Chemical uye Kurapa Kwemvura Simba, neSimba Rakawedzera uye neChikwereti Chakavimbika Tiri kuenda kuedza kuchengetedza mbiri huru seyakanakisa mutengesi wepasirese munyika. Kana iwe uine chero mibvunzo kana mhinduro, iwe unofanirwakusangana nesuzvakasununguka.
