Calu dul ma jwigo piny ma rac, tic ma pire tek uloyu pa kabedo mi yiku pii ma rac utiye ni neno nia pii ma rac urombo ku cik. Ento, ku cik ma tek mi wodhu pii man ku tego pa ju ma gwoko kwo pa piny, ukelo peko madit ikum tic pa kabedo mi yiku pii ma rac. Ebedo tek man tek ni kwanyo pii woko.
Ni lubre ku neno pa jagor, the lembe ma nyayu peko mi nwangu rwom mi pii ma wok kud i pii utiye nia pol kare lembe adek marac nuti i kabedo mi pii ma rac mi ngom mwa.
Mir acel utiye dul ma rac pa tic pa lum ma nok (MLVSS/MLSS) man lum ma lee; mir aryo utiye lembe ma rac ma ka jutiyo ku kemikol ma kwanyo phosphorus madwong, sludge ma juwodho woko ubedo madwong; mir adek utiye kabedo mi yiku pii ma rac ma rii pi kare malac. Tic ma lee, jam tic copo bedu maber ungo, ma wok ku two oro zo, ma kelo peko mi dwoko piny kero mi yiku pii ma rac.

Circle marac pa tic pa lum man dwong pa lum
Japonji Wang Hongchen utimu sayusac ikum 467 pa kabedo mi pii ma rac. Wek wanenu lembe pa tic pa lum man dwong pa lum: Ikind 467 pa kabedo mi lwoko pii, 61% pa kabedo mi lwoko pii ma rac utiye ku MLVSS/MLSS ma piny pa 0.5, 30% pa kabedo mi lwoko pii utiye ku MLVSS/MLSS ma piny pa 0.4.
Kite ma 2/3 pa kabedo mi yiku pii maleng ukadhu 4000 mg/L, dwong pa lum ma 1/3 pa kabedo mi yiku pii ukadhu 6000 mg/L, man dwong pa lum ma 20 mi kabedo mi yiku pii ukadhu 10000 mg/L.
Adwogi pa lembe ma malu eni (tic pa lum ma nok, lum madwong) utiye ango? Kadi bende waneno lembe madwong ma jugoro ma nyang ikum lemandha, ento i wec mayot, adwogi acel utiye, niwacu, pii ma wok kud i pii ukadhu ma juporo.
Eni jucopo gonyo kud i yore aryo. Icing acel, ingey kadhiri pa lum ubedo malo, pi jwigo lum ma nyai, umitu ju med yamo. Medu wel pa yamu bi medo kero pa mac kende ngo, ento bi medo bende dul pa piny ma kwo. Medu pa dissolved oxygen bi kwalo piny ma mitere pi denitrification, ma bi loko denitrification man phosphorus removal effect pa biological system, ma bi kelo N ku P madwong.
Icing ling acel, dwong pa lum ma lee weko lum ku pii umedire, man lum ne rweny yot yot ku pii ma wok kud i tank mi sedimentation mir aryo, ma copo juku advanced treatment unit nyo ketho pii ma wok kud i COD ku SS kadhu rwom.
I ngei wecu ikum adwogi ne, wek wawec ikum pirango ma pol kabedo mi pii ma rac gitiye ku peko mi tic pa lum ma nok man lum ma dwong.
I andha, the lembe ma nyayu rwom ma malu pa lum utiye tic pa lum ma nok. Pien tic pa lum utiye piny, pi medo adwogi pa yath, dwong pa lum ucikere ni medre. Tic pa lum ma nok utiye pi the lembe ma nia pii ma mol utiye ku lum madwong, ma mondo i biological treatment unit man ecokiri moth moth, ma nyayu peko i tic pa microorganisms.
Slag man sand madwong utiye i pii ma bino. acel utiye nia tic pa grille utiye marac akeca, man mukende utiye nia 90% pa kabedo mi yiku pii ma rac i ngom para gi gieru ngo tank mi pii ma rac.
Dhanu moko copo penjo, pirango ngo juyik tank mi pii? Eni utiye pi pipe network. Peko moko nuti calu ret ma rwinyo, rwinyo ma rwinyo, man rwinyo ma rwinyo i pipe network i ngom para. Macalu adwogi, ber pa pii ma wok kud i kabedo mi pii ma rac utiye ku kit adek: rwom ma malu pa piny ma kwo (ISS), COD ma nok, C/N ratio ma piny.
Wel pa piny ma kwo ngo i pii ma mol utiye malo, niwacu, kadhiri pa lum utiye malo. I acaki, tank mi sedimentation ma pire tek copo dwoko piny moko ma kwo ngo, ento pi COD pa pii ma mol i iye utiye piny, pol pa sewage plants gi ketho ngo tank mi sedimentation ma kwong.
I thum pa lembe, tic pa lum ma nok ubedo lanyuth pa "yen ma pek man lum ma yot".
Wawacu nia kadhiri pa lum ma lee man tic ma nok bi kelo N man P madwong in pii ma wok kud i pii. I kare eni, yore mi dwoko wang lembe pa kabedo mapol mi pii ma rac utiye me medo piny ma kelo carbon man inorganic flocculants. Ento, medu pa piny madwong ma wok kudi woko bi medo rwom pa tic ku kero, man medu pa flocculant madwong bi kelo rwom ma malo pa lum, ma bi medo rwom pa lum man dwoko piny pa tic pa lum, ma bi ketho dul ma rac.

Circle ma rac ma ka jutiyo ku kemikol ma kwanyo phosphorus madwong, nwango pii ma juyubu ubedo madwong.
Tic ku kemikol mi kwanyu phosphorus umedire rwom pa lum ku 20% nicidho 30%, nyo makadhu.
Peko pa lum ubedo peko madit pa kabedo mi yiku pii ma rac pi oro madwong, mandha ne pi en epe ku yore mi wok kud i lum, nyo yore mi wok woko epe. .
Eni nyayu dongo pa oro pa lum, ma kelo dongo pa lum, man bende lembe marac ma rac calo lum ma dit.
Sludge ma unyai utiye ku flocculation marac. Ku rweny pa pii ma wok kud i tank mi sedimentation mir aryo, kabedo mi yiko pii ma malu juku, adwogi pa pii ma jucwalo udok piny, man wel pa pii ma jucwalo udok piny.
Medu pa wel pa pii ma jucwalo i ngeye bi kelo adwogi ario, acel utiye ni dwoko piny adwogi pa yath pa thenge mukadho mi biochemical.
Pi madwong ma judwoko cen i tank mi yamo, ma dwoko piny kare mi gwoko pii i ot man dwoko piny adwogi pa yath mir aryo;
Mir aryo utiye mi medo dwoko piny adwogi pa tic pa depth processing unit.
Pien pii madwong ma jucwalo i ngeye umitu judwog i advanced treatment filtration system, rwom mi filtration umedire man kero mi filtration mandha udok piny.
Adwogi pa yath doko marac, ma copo ketho wel pa phosphorus ku COD i pii ma wok kud i pii kadho rwom. Pi nigwoko ngo ma kadho cik, ka gwoko pii ma rac bi medo tic ku piny ma kwanyo phosphorus, ma bi medo wel pa lum.

Lembe marac ma bino pi kare malac mi pong pa kabedo mi lwoko pii man dwoko piny kero mi lwoko pii maleng
Tiyu ku pii ma rac ucungo iwi dhanu kende ngo, ento iwi jam tic de.
Jam tic mi pii ma rac ubedo ka lwiny i wang tic mi yiko pii pi kare malac. Ka juyike ngo kare ku kare, peko biwok kawoni nyo i ngeye. Ento, pol kare, jam tic mi pii ma rac copo yiko ngo, kum ka jam tic moko ucungu, pii ma wok kud i iye copo kadho rwom. I the cik mi cul ma kubang ceng, dhanu ceke copo culo ngo.
Ikind 467 pa kabedo mi yiku pii ma rac ma Professor Wang Hongchen utimo sayusac iwie, acel ikum adek migi utiye ku rwom ma malu pa 80%, acel ikum adek utiye ku rwom ma malu pa 120%, man kabedo 5 mi yiku pii ma rac utiye ma kadhu 150%.
Ka hydraulic load rate ubedo malac uloyu 80%, muweko kabedo moko ma dit mi yiku pii ma rac, kabedo mi yiku pii ma rac copo juku ngo pii pi gwoko pii ikum pii ma wok kud i rwom ma malu, man pii ma jucwalo epe pi aerators man secondary sedimentation tank suction man scrapers. Jam tic ma piny ecopu bedu kende kende ma juyubu nyoke juloko ka pii uthum.
Eni nyutho nya, 2/3 pa kabedo mi pii ma rac copo yiko ngo jam tic pi neno nia pii ma rac uromo ku cik.
Ni lubre ku lembe ma Profesa Wang Hongchen utimo, kwo pa aerators ubedo oro 4-6, ento 1/4 pa kabedo mi pii ma rac timo ngo tic mi yiko yamo iwi aerators pi oro 6. Mud scraper, ma mitire ni juyik man juyik, pol kare juyike ngo oro zo.
Jam tic eca ubedu katiyo ku two pi kare malac, man kero mi yiku pii ubedo ka medere marac. Pi ni ciro peko pa pii, yore moko epe mi juku pi gwoko. I kind lembe ma rac ma kumeno, kare ku kare ebibedo ku yore mi yiko pii ma rac ma bi rwinyo.
