Njengebhizinisi lokulawula ukungcoliswa, umsebenzi obaluleke kakhulu wesitshalo sokwelashwa kwendle ukuqinisekisa ukuthi i-affaent ihlangabezana nezindinganiso. Kodwa-ke, ngezindinganiso zokuphupha ezithuthukile kanye nolaka lwabahloli bezivikelo zezemvelo, ilethe ingcindezi enkulu yokusebenza esiteshini sokwelashwa kwendle. Kunzima ngempela futhi kunzima ukuthola amanzi.
Ngokusho kokuqashelwa ngumlobi, imbangela eqondile yobunzima ekufinyeleleni kokuphuma kwamanzi okujwayelekile ukuthi kunemibuthano emithathu enonya ezitshalweni zendle zezwe lami.
Owokuqala umbuthano ononya womsebenzi ophansi we-sludge (MLVSS / MLSS) kanye nokuhlushwa okuphezulu okuphezulu; Okwesibili yindilinga enonya enkulu yenani lamakhemikhali wokususa ama-phosphorus asetshenzisiwe, okukhipha okuningi kwe-sludge; Okwesithathu ngukusebenza okugcwele kwendle kwendle ukuthuthwa kwendle, imishini ayinakwenziwa ngokweqile, isebenza ngezifo unyaka wonke, okuholela embuthanweni omubi wokuncishiswa kwamandla okulahla indle.

Umbuthano ononya womsebenzi ophansi we-sludge kanye nokuhlushwa okuphezulu okuphezulu
USolwazi wang Hongchen wenze ucwaningo ezitshalweni zendle ezingama-467. Ake sibheke imininingwane yomsebenzi we-sludge kanye nokuhlushwa kwe-sludge: Phakathi kwalezi zitshalo zendle ezingama-467, ama-61% ezinhlamvu zokukhucululwa kwendle zinama-mlvss / mls aphansi kwezitshalo zokwelashwa zinama-mlvs
Ukuhlulwa kwe-sludge kwe-2/3 yezitshalo zokwelashwa kwendle kudlula ama-4000 mg / l, ukuhlanganiswa kwe-sludge kwezitshalo zendle kudlula ama-6000 mg / l, kanye ne-sludge ukugcwala kwezitshalo ezingama-menzis ezingama-20 zedlula i-10000 mg / l.
Yimiphi imiphumela yalezi zimo ezingenhla (umsebenzi ophansi we-sludge, okuhlushwa okuphezulu)? Yize sibone izindatshana eziningi zobuchwepheshe ezihlaziya iqiniso, kodwa ngamagama alula, kunomphumela owodwa, okungukuthi, okukhishwa kwamanzi kudlula izinga.
Lokhu kungachazwa kusuka ezicini ezimbili. Ngakolunye uhlangothi, ngemuva kokuhlushwa kwe-sludge kuphezulu, ukuze kugwenywe ukudilizwa kwe-sludge, kuyadingeka ukukhulisa i-aemoration. Ukwandisa inani le-a a a a a a aution ngeke kukhulise ukusetshenziswa kwamandla kuphela, kepha futhi kwandise isigaba sebhayoloji. Ukwanda kwe-oksijini encibilikisiwe kuzokufaka umthombo wekhabhoni okudingekayo ukuze uyeke ukudelelwa, okuzothinta ngqo umphumela wokukhishwa kanye nokususwa kwe-phosphorus kohlelo lwebhayoloji, okuholela ekunciphiseni ngokweqile
Ngakolunye uhlangothi, ukugxila okuphezulu kwe-sludge kwenza ukuxhumana kwamanzi okuphezulu kwenza ukuthi i-interface yamanzi yodaka ilahlekelwe kalula nge-whedfuent yethangi le-sediment ye-sediment, elizovimba iyunithi yokwelashwa esezingeni eliphakeme noma ibangele i-expluent cod kanye nama-SS ukwedlula okujwayelekile.
Ngemuva kokukhuluma ngemiphumela, ake sixoxe ngokuthi kungani izitshalo eziningi zokuthuthwa kwendle zinenkinga yomsebenzi ophansi we-sludge kanye nokuhlushwa okuphezulu okuphezulu.
Eqinisweni, isizathu sokuhlushwa okuphezulu okuphezulu ngumsebenzi ophansi we-sludge. Ngoba umsebenzi we-sludge uphansi, ukuze uthuthukise umphumela wokwelashwa, ukugxila kwe-sludge kufanele kwandiswe. Umsebenzi ophansi we-sludge ngenxa yokuthi amanzi anamandla aqukethe inani elikhulu lesihlabathi esithambile, esingena kuyunithi yokwelashwa ngokwemvelo futhi siqongelela kancane, okuthinta umsebenzi wama-microorganisms.
Kunenqwaba ye-slag nesihlabathi emanzini angenayo. Eyokuqala ukuthi umphumela wokugagela we-grille umpofu kakhulu, kanti omunye ukuthi ngaphezu kwama-90% wezitshalo zokwehla kwendle ezweni lami azizange zakha amathangi aphambili we-sedimentation.
Abanye abantu bangabuza, kungani ungakhanga ithangi eliyinhloko lokudina? Lokhu kumayelana nenethiwekhi yepayipi. Kunezinkinga ezifana nokuxhunyaniswa, ukuxhumana okuxubile, kanye nokuxhumeka okungekho kwinethiwekhi yepayipi ezweni lami. Ngenxa yalokhu, ikhwalithi yamanzi enethonya lezitshalo zokuthuthwa kwendle ngokuvamile inezici ezintathu: Ukuhlushwa okuphezulu kwe-Inorganic (ISS), isilinganiso seCoD, isilinganiso esiphansi se-C / N.
Ukuqoqwa kwezinsimbi ezingaphakathi emanzini anamandla kuphakeme, okungukuthi, okuqukethwe kwesihlabathi kuphakeme kakhulu. Ekuqaleni, ithangi eliyinhloko le-sedimentation linganciphisa izinto ezithile ezingaphakathi, kodwa ngoba i-cod yamanzi anethonya iphansi, izitshalo eziningi zokuthuthwa zendle zimane nje azikha ithangi eliyindida ledimentation.
Ekuhlaziyeni kokugcina, umsebenzi ophansi we-sludge uyifa lezitshalo ezisindayo namanetha akhanyayo ".
Sishilo ukuthi ukugxila okuphezulu okuphezulu kanye nomsebenzi ophansi kuzoholela ekutholeni ngokweqile n no-P ku-Effeent. Ngalesi sikhathi, izindlela zokuphendula zezitshalo eziningi zendle ukwengeza imithombo yekhabhoni kanye ne-inorganic flocculants. Kodwa-ke, ukungezwa kwenani elikhulu lemithombo ye-carbon yangaphandle kuzoholela ekusetshenzisweni kwamandla okusetshenziswa kwamandla, ngenkathi ukwengeza inani elikhulu le-flocculant kuzokhiqiza inani elikhulu le-sludge yamakhemikhali, okuholela ekunciphiseni kokugxila kwe-sludge kanye nokuncishiswa okwengeziwe emsebenzini we-sludge, kwakha umbuthano onamandla.

Umbuthano ononya lapho imali enkulu khona yamakhemikhali wokususa ama-phosphorus asetshenziswa khona, kukhiqizwa okukhulu kakhulu ukukhiqizwa kwe-sludge.
Ukusetshenziswa kwamakhemikhali okususwa kwe-phosphorus kukhuphule ukukhiqizwa kwe-sludge ngo-20% kuya ku-30%, noma ngisho nangaphezulu.
Inkinga ye-sludge ibe nzima kakhulu kwezitshalo zokwelashwa kwendle kweminyaka eminingi, ikakhulukazi ngoba ayikho indlela yokuphuma e-sludge, noma indlela yokuphuma ingazinzile. .
Lokhu kuholela ekwandeni kwe-sludge age, okuholela ekutheni kube nomphumela wokuguga kwe-sludge, kanye nobunzima obukhulu obufana nokudonswa kwe-sludge bulking.
I-sludge eyandisiwe ine-floccation empofu. Ngokulahleka kwethangi le-sediment elivela ethangini le-sedimentation yesibili, kuvinjelwe iyunithi yokwelashwa okuthuthukile, umphumela wokwelashwa uyancishiswa, futhi inani lamanzi aphezulu ancipha.
Ukwanda kwenani lamanzi angemuva azoholela emiphumeleni emibili, eyodwa ukunciphisa umphumela wokwelashwa wesigaba se-biochemical esedlule.
Inani elikhulu lamanzi angemuva libuyiselwa ethatini le-aoration, elinciphisa isikhathi sangempela sokugcinwa kwe-hydraulic sesakhiwo futhi sinciphise umphumela wokwelashwa kokwelashwa kwesibili;
Okwesibili ukuthuthukisa futhi umphumela wokucubungula weyunithi yokususwa kokujula.
Ngoba inani elikhulu lamanzi angemuva kufanele libuyiselwe ohlelweni lwe-filtration adged advanced, izinga lokuhlunga liyanda futhi umthamo wangempela we-filltration uncishisiwe.
Umphumela wokwelashwa jikelele uba mpofu, okungadala inani le-phosphorus eliphelele ne-cod ku-effluent ukuze weqe izinga. Ukuze ugweme ukwedlula okujwayelekile, isitshalo sendle sizokwandisa ukusetshenziswa kwama-phosphorus akhawulela ama-ejenti, azothuthukisa inani le-sludge.
embuthanweni omubi.

Umbuthano ononya wokugcwala ngokweqile kwezitshalo zokukhucululwa kwendle nokunciphisa umthamo wokwelashwa kwendle
I-secure ukwelashwa kwendle incike kubantu kuphela, kodwa futhi nemishini.
Imishini yokuthuthwa kwendle ibilokhu ilwa emgqeni wangaphambi kokwelashwa kwamanzi isikhathi eside. Uma kungalungiswa njalo, izinkinga zizokwenzeka maduze noma kamuva. Kodwa-ke, ezimweni eziningi, imishini yokuthuthwa kwendle ayinakulungiswa, ngoba uma imishini ethile iyeka, okuphuma kwamanzi kungenzeka kwedlule okujwayelekile. Ngaphansi kohlelo lwenhlawulo yansuku zonke, wonke umuntu akakwazi ukuyikhokhela.
Phakathi kwama-467 ama-Urban Meage Treatment Plants ahlolwe nguProfessor Wang Hongchen, cishe izingxenye ezimbili kwezintathu zazo zinamanani okulayisha ama-hydraulic amakhulu kune-80%, cishe ingxenye eyodwa yokuthuthwa kwendle engaphezu kwama-120%, kanye ne-5 izitshalo zokwethulwa kwendle zinkulu kune-150%.
Lapho izinga lokulayisha le-hydraulic likhulu kune-80%, ngaphandle kwezitshalo ezimbalwa zokwethulwa kwendle ezinkulu zokukhucululwa kwendle, izitshalo zokwehla kwendle okujwayelekile azikwazi ukuvala amanzi ukuze i-eressuent ifinyelela ezingeni, futhi akukho manzi okulondolozwa kwamathanga okuhlanza amakati. Imishini engezansi ingafakwa ngaphezulu ngokuphelele noma ithathelwe indawo lapho ikhishwa.
Lokho kusho ukuthi, cishe ngo-2/3 wezitshalo zokukhucululwa kwendle ngeke kulungise imishini esesimweni sokuqinisekisa ukuthi i-affaent ihlangabezana nezinga.
NgokukaProfessor wang Hongchen ucwaningo luka-Hongchen, i-Lifespan of Aerators imvamisa yiminyaka engu-4-6, kepha u-1/4 wezitshalo zendle akenzanga ukulungiswa komoya ku-Aerator iminyaka eyi-6. Isikebhe sodaka, esidinga ukudedelwa futhi silungiswe, ngokuvamile asilungiswa unyaka wonke.
Imishini ibilokhu isebenza ngokugula isikhathi eside, futhi amandla okulashwa kwamanzi aya ngokuya enza kabi. Ukuze umelane nengcindezi yesitolo samanzi, ayikho indlela yokukuvimba ukulungiswa. Embuthanweni ononya kangako, kuzohlala kukhona uhlelo lokwelashwa lwendle oluzobumba ukuwa.

Bhala ekugcineni
Ngemuva kokuvikelwa kwezemvelo kwasungulwa njengenqubomgomo yesisekelo yezwe lami, amasimu amanzi, igesi, ukuqina kwenhlabathi, inhlabathi kanye nokunye ukungcoliswa kokungcoliswa kokulawulwa kwasungulwa ngokushesha, phakathi kwensimu yokwelashwa kwendle kungashiwo ukuthi unguMholi. Izinga elinganele, ukusebenza kwesitshalo sendle sekuwele kwinkinga, futhi inkinga yenethiwekhi yepayipi kanye ne-sludge sekube yimaphutha amabili amakhulu emboni yezokuthuthwa kwendle yezwe lami.
Futhi manje, sekuyisikhathi sokwenza ukushiyeka.
