Ukuqaliswa kweNkqubo elula yoNyango lweLindle

Inkqubo yokucocwa kwelindle yahlulwe yangamanqanaba amathathu:
Unyango oluphambili: unyango lomzimba, ngonyango lomatshini, njenge-grille, i-sedimentation okanye i-air flotation, ukususa amatye, isanti kunye negrabile, i-fat, igrisi, njl. equlethwe kumdaka.
Unyango lwesibini: unyango lwe-biochemical, ukungcola kumanzi amdaka athotywa kwaye aguqulwa abe yi-sludge phantsi kwesenzo se-microorganisms.
Unyango olukwinqanaba eliphezulu: unyango oluphucukileyo lwelindle, oluquka ukususwa kwezondlo kunye nokubulala iintsholongwane kwilindle ngeklorini, imitha ye-ultraviolet okanye ubuchwepheshe be-ozone.Ngokuxhomekeke kwiinjongo zonyango kunye nomgangatho wamanzi, ezinye iinkqubo zokucocwa kwamanzi amdaka azibandakanyi zonke ezi nkqubo zingentla.
01 Unyango lokuqala
Icandelo lonyango lomatshini (inqanaba lokuqala) libandakanya izakhiwo ezifana ne-grilles, i-grit chambers, iitanki ze-sedimentation eziphambili, njl., Ukususa amaqhekeza anqabileyo kunye nezinto eziqinileyo ezimisiwe.Umgaqo wonyango kukufezekisa ukuhlukana okuqinileyo-ulwelo oluqinileyo ngeendlela eziphathekayo kunye nokwahlula ukungcola kumdaka, eyona ndlela isetyenziswa ngokuqhelekileyo yokucoca ukungcola.
Unyango lweMechanical (oluphambili) yiprojekthi eyimfuneko kuzo zonke iinkqubo zokucocwa kwamanzi amdaka (nangona ezinye iinkqubo ngamanye amaxesha zishiya itanki yokulahla intlenge ephambili), kunye namazinga okususwa aqhelekileyo e-BOD5 kunye ne-SS kunyango oluphambili lwelindle ezidolophini ngama-25% kunye nama-50%, ngokulandelanayo. .
Kwizityalo ze-biological phosphorus kunye ne-nitrogen yokucocwa kwamanzi amdaka, amagumbi e-aerated grit ngokuqhelekileyo awakhuthazwa ukuba aphephe ukususwa kwezinto eziphilayo ezikhawulezayo;xa iimpawu zomgangatho wamanzi we-lindle ekrwada azihambisani nokususwa kwe-phosphorus kunye ne-nitrogen, ukusetwa kwe-sedimentation yokuqala kunye nokumisela Indlela kufuneka ihlalutywe ngononophelo kwaye iqwalaselwe ngokwenkqubo yokulandelela iimpawu zomgangatho wamanzi, ukwenzela ukuba kuqinisekiswe. kunye nokuphucula umgangatho wamanzi onempembelelo kwiinkqubo zokulandelela ezifana nokususwa kwe-phosphorus kunye nokukhutshwa kwe-denitrification.
02 Unyango lwesibini
Ugutyulo lwemichiza yelindle lolonyango lwesibini, ngeyona njongo iphambili yokususa izinto eziqinileyo ezingatshoniyo kunye nezinto eziphilayo ezinokunyibilika.Ukubunjwa kwenkqubo yayo kuyahluka, enokuthi ihlulwe ibe yindlela ye-sludge esebenzayo, indlela ye-AB, indlela ye-A / O, indlela ye-A2 / O, indlela ye-SBR, indlela ye-oxidation ye-ditch, indlela yokuzinza echibini, indlela ye-CASS, indlela yokunyanga umhlaba kunye nezinye iindlela zonyango.Okwangoku, uninzi lwezityalo zokucocwa kwamanzi amdaka ezidolophini zisebenzisa indlela yodaka olusebenzayo.
Umgaqo wonyango lwebhayoloji kukugqiba ukubola kwezinto eziphilayo kunye nokuhlanganiswa kwezinto eziphilayo ngesenzo sebhayoloji, ngakumbi isenzo se-microorganisms, kunye nokuguqula izinto ezingcolisa izinto eziphilayo zibe yimveliso yegesi engenabungozi (CO2), iimveliso zolwelo (amanzi) kunye neemveliso ezityebileyo. .Imveliso eqinileyo (iqela le-microbial okanye i-biological sludge);udaka lwebhayoloji olugqithileyo lwahlulwe kokuqinileyo kunye nolwelo kwitanki yentlenga kwaye lususwe kugutyulo olucociweyo.i
03 Unyango oluphezulu
Unyango lwenqanaba lesithathu lolona nyango luphezulu lwamanzi, oluyinkqubo yokucocwa kwamanzi amdaka emva konyango lwesibini, kwaye lelona nyathelo liphezulu lokucoca amanzi amdaka.Okwangoku, azikho iindawo ezininzi zokucocwa kwelindle kwilizwe lethu ezifakwe kwisicelo esisebenzayo.
Iyawachasa kwaye yenze iphosphorize yamanzi emva konyango lwesibini, isusa ungcoliseko oluseleyo emanzini nge-activated carbon adsorption okanye i- reverse osmosis, kwaye ibulala iintsholongwane nge-ozone okanye i-chlorine yokubulala iintsholongwane kunye neentsholongwane, emva koko ithumele amanzi acociweyo kwi-Waterways asetyenziswa njenge imithombo yamanzi yokugungxula izindlu zangasese, izitrato zokutshiza, ukunkcenkceshela amabhanti aluhlaza, amanzi avela kwimizi-mveliso, kunye nokuthintela umlilo.
Ingabonwa ukuba indima yenkqubo yokucocwa kwamanzi amdaka kuphela ngokuguqulwa kwe-biodegradation kunye nokuhlukana okuqinileyo kolwelo, ngelixa uhlambulula ukungcola kunye nokutyebisa izinto ezingcolileyo kwi-sludge, kubandakanywa udaka oluphambili oluveliswa kwicandelo lokuqala lonyango, I-sludge eseleyo esebenzayo. iveliswe kwicandelo lonyango lwesibini kunye nodaka lwekhemikhali oluveliswe kunyango oluphezulu.
Ngenxa yokuba ezi nkunkuma ziqulethe inani elikhulu lezinto eziphilayo kunye ne-pathogens, kwaye zonakaliswe ngokulula kwaye zivumba, kulula ukubangela ukungcola okwesibini, kwaye umsebenzi wokuphelisa ukungcola awukagqitywa.I-sludge kufuneka ilahlwe ngokufanelekileyo ngokunciphisa umthamo othile, ukunciphisa umthamo, ukuzinzisa kunye nonyango olungenabungozi.Impumelelo yonyango lwe-sludge kunye nokulahlwa kwayo kunempembelelo ebalulekileyo kwisityalo sogutyulo kwaye kufuneka ithathelwe ingqalelo.
Ukuba i-sludge ayiphathwanga, i-sludge iya kufuneka ikhutshwe ngamanzi ahlambulukileyo ahlambulukileyo, kwaye umphumo wokucocwa kwesityalo sogutyulo uya kulungiswa.Ke ngoko, kweyona nkqubo yokufaka isicelo, unyango lwe-sludge kwinkqubo yokucoca ugutyulo lubaluleke kakhulu.
04 Inkqubo yokuphelisa ivumba
Phakathi kwazo, iindlela zokoqobo ziquka indlela yokuhlanjululwa, indlela ye-adsorption, njl.;iindlela zekhemikhali ziquka indlela yokufunxa, indlela yokutshisa, njl.;ishawa njl.

Ubudlelwane phakathi kokucocwa kwamanzi kunye novavanyo lomgangatho wamanzi
Ngokuqhelekileyo, izixhobo zokuvavanya umgangatho wamanzi ziya kusetyenziswa kwinkqubo yokucocwa kwamanzi amdaka, ukwenzela ukuba siyazi imeko ethile yomgangatho wamanzi kwaye sibone ukuba idibana nomgangatho!
Uvavanyo lomgangatho wamanzi luyimfuneko kunyango lwamanzi.Ngokubhekiselele kwimeko yangoku, amanzi amaninzi nangakumbi asetyenziswa ebomini nakwishishini, kwaye amanye amanzi amdaka ebomini kunye nogutyulo kwimveliso yemizi-mveliso nawo ayanda.Ukuba amanzi akhutshwa ngokuthe ngqo ngaphandle kokuphuma, akayi kungcolisa imo engqongileyo kuphela, kodwa aphinde wonakalise kakhulu inkqubo yendalo esingqongileyo.Ngoko ke, kufuneka kubekho ulwazi malunga nokukhutshwa kwamanzi amdaka kunye nokuvavanya.Amasebe afanelekileyo achaze izalathi ezifanelekileyo zokukhupha ukucocwa kwamanzi.Kuphela emva kokuvavanya kunye nokuqinisekisa ukuba imigangatho idibene nayo inokukhutshwa.Ukufunyanwa kwamanzi amdaka kubandakanya izalathisi ezininzi, ezifana ne-pH, izinto eziqinileyo ezimisiweyo, i-turbidity, imfuno ye-oksijini yeekhemikhali (COD), imfuno ye-oksijini ye-biochemical (BOD), i-phosphorus iyonke, i-nitrogen iyonke, njl. umgangatho sinokuqinisekisa umphumo wokucoca amanzi, ukufezekisa injongo yokukhusela okusingqongileyo.
