Iindidi zeeNkqubo zokucocwa kwamanzi amdaka ngeAerobic kunye nezinto eziluncedo zazo

TL; DR: Nearly 80% of the world’s wastewater is still discharged untreated. Aerobic wastewater treatment uses oxygen-dependent microbes to break down organic pollutants, nitrogen and phosphorus during the secondary treatment stage, with blowers or compressors supplying air. The three main systems are conventional activated sludge, membrane bioreactors (MBR) and moving bed bioreactors (MBBR). Compared with anaerobic treatment, aerobic systems give less odour, convert ammonia to nitrate and cut methane emissions.

Ngowama-2024, imfuno yonyango lwamanzi amdaka olusebenzayo noluzinzileyo iphezulu kakhulu, iqhutywa kukwanda kokukhutshwa kwamanzi kwimizi-mveliso, imingeni yamanzi amdaka ezidolophini, kunye nemithetho engqongqo yokusingqongileyo.

NgokweNgxelo yeManzi yeZizwe eziManyeneyo , phantse i-80% yamanzi amdaka ehlabathi akhutshwa enganyangwanga , nto leyo ekhokelela kungcoliseko olukhulu lwamanzi.

Njengoko oorhulumente kunye namashishini begxile kwizisombululo zonyango lwamanzi amdaka ezisasazwa kwiindawo ezahlukeneyo, iindlela zonyango lwebhayoloji - ingakumbi unyango lwamanzi amdaka nge-aerobic - ziye zaduma ngenxa yokusebenza kwazo kakuhle ekuqhekezeni ungcoliseko ngelixa zinciphisa imveliso yodaka kunye nokukhutshwa kwegesi ezibangela ubushushu.

Ngokuqhelekileyo, indawo yokucocwa kwamanzi amdaka iqhuba iinkqubo ezintathu ezibalulekileyo: Iprayimari, iSekondari, kunye neTertiary, apho isigaba sonyango lwebhayoloji siwela phantsi kwenqanaba lesibini.

Isigaba sonyango lwebhayoloji ikakhulu siziindidi ezimbini: Unyango lweAerobic kunye noNyango lweAnaerobic.

Ukucocwa kwamanzi amdaka ngeAerobic kusebenzisa ioksijini ukuthomalalisa ungcoliseko lwendalo kunye nezinye izinto ezingcolisayo ezifana nenitrogen kunye nephosphorus.

Isixhobo somatshini sokungenisa umoya, esifana nesivuthelo somoya okanye icompressor, senza amaqamza omoya ukuba asebenzele iinjongo ezimbini eziphambili: ukuphefumla kunye nokuphazamiseka.

I-Aeration ibonelela ngeoksijini kumanzi amdaka, esetyenziswa ziintsholongwane ze-aerobic ezikhawulezisa ukonakaliswa kwamanzi amdaka.

Ubungakanani beoksijini enyityilisiweyo efunwa zizidalwa ze-aerobic ukophula izinto eziphilayo zibe ziimolekyuli ezincinci zaziwa njengemfuno ye-oksijini yebhayoloji okanye iBOD.

Isetyenziswa rhoqo ukubala ukuthotywa kwezi ntsholongwane kwizingcolisi eziphilayo.

Ukwazisa ungcoliseko olufana nokukhutshwa kwimizi-mveliso, inkunkuma yelindle yasekhaya, okanye ukubaleka kwesichumiso kunokukhokelela kumanqanaba aphezulu e-BOD, nto leyo ebonisa ukuxinana okuphezulu kwezinto ezinokuboliswa yi-biodegradable kumanzi amdaka.

Ngenxa yokuba ezi zinto ziphilayo zidinga ioksijini, iinkqubo ze-aerobic zifuna indlela yokuyinikezela kwi-biomass.

Oku kunokwenziwa ngokubandakanya amachibi okucoca amanzi amdaka- abonelela ngomphezulu wendawo enkulu yokungenisa umoya kumanzi amdaka, okanye ngokubandakanya izixhobo zokuphefumla ngoomatshini.

Emva kokuqonda injongo yokucoca amanzi amdaka, makhe sihlalutye ukusebenza kwenkqubo yonyango.

Zisebenza Njani Iinkqubo zokucocwa kwamanzi amdaka ngeAerobic?

Inkqubo yokucocwa kwamanzi amdaka ebhayoloji inokubandakanya iinkqubo ezininzi kunye neentlobo ngeentlobo zemicroorganisms, kuxhomekeke kubume bemichiza yamanzi amdaka kunye neemfuno zamanzi amdaka.

Ukongeza, baya kufuna iinkqubo ezithile zokusebenza eziza kutshintsha ngokusekwe kwindawo efunekayo ukuze kugcinwe amazinga okukhula kwebhayomass alungele abantu abathile bentsholongwane.

Ngokomzekelo, kudla ngokuyimfuneko ukubeka iliso kunye nokuguqula i-aeration ukuze kugcinwe inqanaba le-oksijini edibeneyo kunye nokugcina iibhaktheriya kwinkqubo ephindaphinda kwisantya esifanelekileyo ukuhlangabezana nemigangatho yokukhupha.

Ukongeza kwioksijini enyibilikisiweyo, iinkqubo zebhayoloji zihlala zilungelelaniswa ukuhamba, umthwalo, i-pH, ubushushu, kunye nezondlo.

Ngoku siyiqonda indlela asebenza ngayo, masifunde malunga neentlobo zeenkqubo zokucocwa kwamanzi amdaka.

Iintlobo ze-Aerobic Waste Water Treatment Systems

Udaka oluqhelekileyo olusebenzayo

Wastewaters from the primary treatment phase enter an aeration tank, where activated sludge processes kwenzeka.

Emva kwe-aeration, i-organic material iyaphulwa kwaye igqitywe ngokunqunyanyiswa (idada ngokukhululekileyo) i-aerobic microorganisms, ekhokelela kwizinto eziqinileyo zebhayoloji ezijikelezayo zibe ziziqwenga ezinkulu okanye iiflocs.

Amanzi amdaka ahlukaniswe kwiiflocs ezimisiweyo ngentlenga emva kokungena kwitanki yokumisa okanye i-clarifier.

I-biomass ephuhlisiweyo ilawulwa ngokurisayikilisha udaka olusebenzayo kwitanki yokuphefumla, ngelixa izinto eziqinileyo ezongezelelweyo zilahlwa njengodaka.

Iinkqubo zokucocwa kodaka olusebenzayo zihlala zifuna indawo eninzi kwaye zivelise izixa ezikhulu zodaka, ezineendleko zokulahlwa ezinxulumene nalo.

Sekunjalo, iindleko zabo ezinkulu kunye nokugcinwa kwazo zincinci xa kuthelekiswa nezinye izisombululo.

I-Membrane bioreactor (MBR)

Ii-MBRs ziitekhnoloji zebhayoloji zokucocwa kwamanzi amdaka ezidibanisa udaka lwesiqhelo olunqunyanyisiweyo kunye nokuhluzwa kwenwebu, endaweni yentlenga, ukwahlula kunye nokuphinda kusetyenziswe izinto eziqinileyo ezimisiweyo.

I-MBR eqhelekileyo inokuquka iitanki zonyango lwe-aerobic (okanye i-anaerobic in anaerobic), inkqubo yokuphefumla, imixube, itanki ye-membrane, isixokelelwano sendawo ecocekileyo, kunye nokuba yifayibha engenanto okanye i-flat sheet ultrafiltration membrane.

Ngenxa yeenxalenye zayo ezininzi kunye neenkqubo zokucoca, ziyaziwa ngenkunzi ephezulu, iindleko zokusebenza kunye nokugcinwa kwazo.

Ukuhambisa i-bioreactors yebhedi (MBBRs)

IiMBBR zihlala zineetanki zomoya ezizaliswe ziinqwelo ezincinci ze-polyethylene biofilm ezihambayo ezigcinwe kwinqanawa zizihluzo zokugcina imidiya.

Ngenxa yokunqunyanyiswa kwezithuthi ezihambayo ze-bio-film, ii-MBBR zivumela amanzi amdaka aphezulu e-BOD ukuba aphathwe kwindawo encinci ngaphandle kokuvaleka.

Abacacisi besibini baqhele ukusetyenziswa emva kwe-MBBRs, kodwa akukho ludaka luphinda lusetyenziswe kwakhona kwinkqubo.

Udaka olugqithisileyo luhlala, oluqokelelwa kwi-slurry kwaye luhanjiswe njengenkunkuma eqinile, okanye i-slurry isuswe yilori ye-vacuum.

Emva kokuqonda iinkqubo ezintathu ezibandakanyekayo kwiinkqubo zamanzi amdaka e-aerobic, ngaba uyazazi iingenelo zokufakela le nkqubo kwindawo yakho yokucoca amanzi amdaka?

Izinto eziluncedo kwiiNkqubo zeAerobic Waste Water Treatment

Unyango lwe-Aerobic ludinga ukunikezelwa kwe-oksijini ukugcina i-microorganisms ye-aerobic.

Xa kuthelekiswa nonyango lwe-anaerobic, ukungenisa umoya kunoncedo lokunciphisa ivumba, ukufakwa kwe-nitrification ye-ammonia ukuya kwi-nitrate (enokuthi yehlise ukukhutshwa kwe-ammonia), ukuba nefomu yenitrogen efumaneka lula kwizityalo kodwa nokuba sengozini yokuvuza, kunye nokunciphisa iigesi ze-greenhouse, ingakumbi i-methane.

Yinkqubo ethembekileyo, ecacileyo, nesebenzayo enceda ekuphuculeni umgangatho wamanzi amdaka, iwenza alungele ukusetyenziswa.

Udaka olusisiphumo alunavumba kwaye lunokuphinda lusetyenziswe njengezichumisi zendalo kwishishini lezolimo.

Nangona kunjalo, ngamanye amaxesha, ezi nkqubo zinokungasebenzi kakuhle ukuba iintsholongwane azikwazi ukunyanga ukungcola kwamanzi.

Ukoyisa imiba enjalo, siye saqhuba iminyaka yophando kwaye senze izisombululo ezinokuphucula ukusebenza ngokubanzi kwendawo yokucocwa kwamanzi amdaka ngaphandle kokwenza utshintsho olukhulu kwinkqubo ekhoyo.

The microbial strain helps reduce high COD/BOD levels, reduce sludge volumes, reduce high TSS levels and improve the plant’s efficiency.

Imibuzo ebuzwa rhoqo (FAQs)

What is aerobic treatment?

Aerobic treatment is a biological wastewater treatment process that uses oxygen-dependent microbes to break down organic pollutants, nitrogen and phosphorus. Air blowers or compressors supply oxygen and keep the effluent mixed. It forms part of the secondary treatment stage, produces less odour than anaerobic treatment and leaves sludge that can be reused as fertiliser.
