Aoyue Refrigeration ine advanced sewage treatment system.Muna 2013, maererano nechikumbiro chehurumende, takavamba hurongwa hwedu hwekuchenesa tsvina.Mvura yetsvina yemumaindasitiri inogona kuburitswa chete mushure mekucheneswa netsvina uye kusangana nemiyero yekubuda.

Kazhinji, tinokamura nzira yekurapa kuita matanho makuru mana: pre-kurapa, biological treatment, advanced treatment, uye sludge treatment.Nheyo yemazuva ano yekuchenesa tsvina ndeyekurapwa kwehutachiona (hutachiona).Iyo biotechnology inodyara tupukanana kuti idye zvinosvibisa pari zvino ndiyo inoshanda zvakanyanya, isingadhuri, uye ine hushamwari hwekuchengetedza tsvina tekinoroji pakati penzira dzese dzekurapa.

1.Pre processing

Pretreatment ndeye anotevera microbial (mabhakitiriya) kurapwa masevhisi (kunze kwechikamu chidiki chemvura yakasviba isingashandisi kurapwa kwehutachiona).Sezvo iri microorganism, inenge iine zvimwe zvinokosha zvinodiwa.Iyo yakawanda inosangana nemamiriro ekurarama kwayo, iyo inokura yakasimba uye zviri nani iyo ichabata tsvina.Semuenzaniso, tembiricha, tupukanana twakawanda zvinokura zvakanyanya pa30-35 madhigirii Celsius, ine pH ye6-8 uye isina inhibitory kana chepfu zvinhu.Zvinosvibisa zvinofanira kuva nyore kudya, zvakadai sezviya zvakafanana nemichero uye kwete plastiki.Uyewo, kuwanda kwemvura hakufaniri kunge kwakanyanyisa kana kuderera kwekanguva, kuitira kudzivirira ma microorganisms kubva pakufa kana kufa nenzara, nezvimwewo.

Saka pane kunyanya nzira dzinotevera dzepreprocessing:

Grille: Chinangwa chegrille ndechekubvisa marara makuru akadai semucheka, mapepa, nezvimwewo kubva mumvura, kuitira kuti usakanganisa kushanda kwepombi yemvura mune ramangwana.Dziva rekudzora: Panguva yekushanda kwefekitori, zvinowanzodikanwa kudhiza uye kusabvisa mvura panguva imwe chete, kuburitsa mvura yakakora panguva imwe chete, uye kuburitsa mvura yakareruka panguva imwe chete.Iko kushanduka kwakakosha, asi kunotevera kugadzirisa kunofanirwa kunge kwakafanana.Dziva rekutonga ndiro tangi rekuchengetedza mvura, uko mvura kubva kumashopu akasiyana uye nguva dzenguva inotanga kuiswa mune rimwe dziva.Iri dziva rinowanzoda kuve rakashongedzerwa nhanho dzinokurudzira, senge aeration kana mechanical kubvongodza, kusanganisa mvura yakasiyana-siyana zvakaenzana.Kana iyo acidity uye alkalinity mushure mekusanganiswa isiri pakati pe6 ne9, zvinowanzodiwa kuwedzera asidhi kana alkali kugadzirisa.

Temperature regulation equipment: Chinangwa ndechekugadzirisa tembiricha kuti ienderane nemhando iyo microorganisms inogona kumira nazvo.Kazhinji ishongwe inotonhorera kana hita.Kana iyo tembiricha pachayo iri mukati mehuwandu, saka chikamu ichi chinogona kubviswa.

Dosing pretreatment.Kana pane zvakawanda zvakamiswa zvakasimba kana kuwanda kwezvinosvibisa mumvura, kuitira kuderedza kudzvinyirira kwehutachiona hwehutachiona, mishonga yemakemikari inowanzowedzerwa kuderedza chikamu chezvinosvibisa uye zvakamiswa zvakasimba.Midziyo yakashongedzerwa pano inowanzo tenderera mhepo kana dosing sedimentation tank.Detoxification uye chain breaking treatment.Iyi nzira yekurapa inowanzo shandiswa kune yakakwira, yakaoma kudzikisira, ine muchetura tsvina yemvura mumakemikari, mishonga, uye mamwe maindasitiri.General nzira dzinosanganisira iron kabhoni, Fenton, electrocatalysis, zvichingodaro.Kuburikidza nemitoo iyi, zviri mukati mezvinosvibisa zvinogona kazhinji kuderedzwa zvakanyanya, uye zvimwe zvinhu zvisingagoni kurumwa netwupukanana zvinogona kutemwa mumuromo wakanaka, kushandura zvinhu zvine chepfu kuita zvisina muchetura kana kuti muchetura wakaderera.

2. Chikamu chekurapa kwehutachiona

Zvichitaurwa zviri nyore, ndima iyi inoreva mamwe madziva kana matangi anorima tupukanana kuti tidye zvinosvibisa, izvo zvakakamurwa kuita anaerobic uye aerobic nhanho.

Iyo anaerobic nhanho, sekureva kunoita zita, idanho rekuita apo anaerobic microorganisms inorimwa kuti idye zvinosvibisa.Chinhu chakakosha cheichi danho ndechekuedza kuchengetedza muviri wemvura kubva pakuburitsa okisijeni zvakanyanya sezvinobvira.Kuburikidza nechikamu cheanaerobic, chikamu chikuru chezvinosvibisa chinogona kudyiwa.Panguva imwecheteyo, zvinoshamisa kuti zvimwe zvinosvibisa zvisingagoni kurumwa neAerobic organism zvinogona kutemwa muzvikamu zviduku zviri nyore kudya, uye zvakakosha ne-zvigadzirwa zvakadai sebiogas zvinogonawo kugadzirwa.

Chikamu cheAerobic chikamu cheMicrobiological tsika uko okisijeni inodiwa kuti urarame.Midziyo inofanirwa kuve yakashongedzerwa panguva ino ndeye oxygenation system, iyo inozadza mvura neokisijeni kuti tupukanana tufe.Panguva ino, chete nekupa oxygen yakakwana, kudzora tembiricha uye pH, tupukanana tunogona kushandisa zvinosvibisa zvinosvibisa, zvichideredza zvakanyanya kutarisisa kwavo, uye mutengo waunoshandisa unongori mutengo wemagetsi weiyo okisijeni yekuchaja fan.Haisi kunyanya kudhura here?Hongu, ma microorganisms acharamba achibereka uye achifa, asi zvakazara, anoberekana nekukurumidza.Mitumbi yakafa yeaerobic microorganisms uye mimwe miviri yemabhakitiriya inobatana kuita sludge yakagadziriswa.Iyo inoyerera ine yakawanda yakawanda yakagadziriswa sludge, iyo inofanirwa kupatsanurwa kubva mumvura.Activated sludge, inozivikanwawo sema microorganisms, inowanzo shandiswa zvakare uye kudyiswa mutangi reaerobic, nepo chikamu chidiki chinobudiswa kuti chiome uye kutakura mvura.

3. Kurapa kwepamusoro

Mushure mekurapa microbial, kuwanda kwezvinosvibisa mumvura hakuchina zvakanyanya kana kuderera zvakanyanya, asi panogona kunge paine zvimwe zviratidzo zvinopfuura mwero, senge cod, ammonia nitrogen, chromaticity, heavy metals, etc. Panguva ino, mamwe kurapwa inodiwa kune zvakasiyana-siyana zvinosvibisa zvinopfuura.Kazhinji, kune nzira dzakadai semhepo flotation, physicochemical precipitation, kupwanya, adsorption, nezvimwe.

4. Sludge treatment system

Chaizvoizvo, makemikari uye zvipenyu nzira dzinoburitsa huwandu hwakati wandei hwematope, ane hunyoro hwakanyanya hwemvura ingangoita 99%.Izvi zvinoda kubviswa kwemvura zhinji.Panguva ino, dehydrator inofanira kushandiswa, kunyanya ine bhandi michina, furemu muchina, centrifuges, uye screw stacking michina, kurapa mvura iri mumatope kusvika anenge 50% -80%, uye wozoitakura kuenda kunoraswa, zvidyarwa zvemagetsi. , mafekitari ezvidhina, nedzimwe nzvimbo.
