Gin ma kelo peko i kom tic pa lum ma nok ki dwong pa lum
Lapwony madit Wang Hongchen otimo kwed i kom 467 kabedo ma ki gwoko iye pii ma obale. Wek wanenu ngec ma mako tic pa lum ki dwong pa lum: I kin 467 pa ka gwoko pii ni, 61% pa ka gwoko pii ni tye ki MLVSS/MLSS ma piny ki 0.5, ma romo 30% pa ka gwoko pii ni tye ki MLVSS/MLSS ma piny ki 0.4.
Kit ma lum ma tye i 2/3 pa ka gwoko pii ma ki tiyo kwede okato 4000 mg/L, dwong pa pii ma tye i 1/3 pa ka ma ki yubu iye pii ma ki tiyo kwede okato 6000 mg/L, ki dwong pa lum ma tye i 20 ma ki yubu ki pii ma ki tiyo kwede kato 10000 mg/L.
Adwogi ango ma bino pi jami ma ki waco malo ni (tic pa lum ma nok, lum ma dwong)? Kadi bed ni waneno jami mapol ma ki coyo ma nyamo lok ada, ento i lok ma yot, tye adwogi acel, ma en aye ni, pii ma ki kato ki iye kato ma ki miito.
Man ki twero gonyo ne ki yoo aryo. Ki tung cing acel, inge dwong pa lum ma opong, me gengo lum ma opong, omyera ki med yamo. Medo dwong pa yamo pe obi medo tic ki teko keken, ento bene bi medo dul ma kwako jami makwo. Medo pa yamo ma ki lwongo ni dissolved oxygen obi kwanyo gin ma ki lwongo ni carbon ma mite pi denitrification, ma obi gudu denitrification ki kwanyo phosphorus ki i kom jami makwo, ma obi kelo N ki P madwong.
Ki tung cing kany, dwong pa pii ma opong ni miyo pii ki ngom ni mede, ki pii ni rweny oyotoyot ki pii ma aa ki i tank me aryo, ma obi juku yub me gwoko pii ma malo ni onyo weko COD ki SS kato ma ki keto.
Iyonge lok i kom adwogi ne, wek wa lok i kom gin mumiyo pol pa ka gwoko pii maleng tye ki peko me tic pa lum ma nok ki lum ma opong.
Ki adaa, tyen lok me dwong pa lum ma opong ni tye pi tic pa lum ma nok. Pien tic pa lum ni nok, me medo rwom me yat ni, dwong pa lum ni omyera ki med. Tic pa lum ma nok ni tye pien pii ma tye ka mol ni tye ki lum madwong, ma donyo i ot ma ki gwoko iye jami ma kwo ki dongo mot mot, ma balo tic pa jami makwo matino tino.
Tye lum ki kweyo madwong i pii ma tye ka bino ni. acel tye ni tic pa grille ni rac tutwal, ki mukene ni ma kato 90% pa ka gwoko pii ma ki tiyo kwede i lobo na pe gu gero tank ma ki tiyo kwede me gwoko pii.
Dano mogo romo penyo ni, pingo pe ki gero tank ma ki lwongo ni primary sedimentation tank? Man kwako dul ma ki lwongo ni paip network. Peko tye calo rweny pa kubbe, kubbe ma rwate, ki rweny pa kubbe i paip i lobo na. Kit ma adugi ne tye kwede, rwom me pii ma tye i kin pii ma ki tiyo kwede i ot yat pol kare tye ki kit adek: rwom ma malo pa jami ma pe kwo (ISS), COD ma lapiny, C/N ma lapiny.
Kit ma jami ma pe kwo tye kwede i pii ma tye ka mol ni tye malo, ma en aye ni, rwom me kweyo tye malo. I acaki, tank me gwoko pii ma pire tek onongo twero dwoko piny jami mogo ma pe kwo, ento pien COD pa pii ma tye ka mol iye tye piny, pol pa kabedo me gwoko pii pe gi gero tank me gwoko pii ma pire tek.
I agiki me nyamo ne, tic pa lum ma nok obedo gin ma oa ki i "jami ma pek ki jami ma yot".
Wa waco ni rwom me pii ma malo ki tic ma nok obi kelo N ki P madwong i pii ma mol. I kare ni, yoo me gamo lok pa pol pa jami ma ki tiyo kwede me kwanyo yugi tye me medo jami ma kelo yamo ma ki lwongo ni carbon ki inorganic flocculants. Ento, medo wel ma dit pa jami ma aa ki woko obi kelo dongo i tic ki teko, kun medo wel flocculant madwong obi kelo wel ma dit pa lum ma ki lwongo ni chemical sludge, ma obi medo wel sludge ki dwoko piny tic pa sludge, ma obi kelo peko.

Gin ma kelo peko ma ka ki tiyo ki jami ma kwanyo phosphorus madwong, ci pii ma ki yubu ni bedo madwong.
Tic ki jami ma kwanyo phosphorus omedo rwom me yubu lum ki 20% onyo 30%, onyo makato.
Peko me lum obedo peko madit bot dano ma gi tiyo ki pii ma obale pi mwaki mapol, tutwale pien yoo me kato ki i lum ni pe, onyo yoo me kato ki iye ni pe ocung matek. .
Man kelo kare me dongo pa lum, ma kelo lok me dongo pa lum, ki bene kelo peko mapol calo dongo pa lum.
Gin ma ki lwongo ni expanded sludge ni tye ki flocculation ma goro. Ki rwenyo pa pii ma aa ki i tank me aryo, yub me gwoko pii ma malo ni ki umu, adwogi me yubu pii ni dwoko piny, ki wel pii ma ki tiyo kwede me lwoko pii ni mede.
Medo wel pii ma ki tiyo kwede me lwoko pii obi kelo adwogi aryo, acel tye me dwoko piny adwogi me tic ki dul ma okato ni.
Pii madwong ma ki lwoko cen ki dwoko cen i tank me yamo, ma dwoko piny kare me gwoko pii i ot ki dwoko piny adwogi me tic ki yat me aryo;
Me aryo tye me medo dwoko piny adwogi pa tic pa gin ma ki lwongo ni depth processing unit.
Pien wel pii madwong ma ki lwoko cen omyera ki dwoko cen i yub me lwoko ma malo, rwom me lwoko ne omede ki kero me lwoko ne odok piny.
Adwogi me tic ki yat ni bedo marac, ma twero weko wel phosphorus ki COD ma tye i pii ni kato ma ki miito. Me gengo kato ma ki miito, ka gwoko pii ma ki lwongo ni sewage plant obi medo tic ki jami ma kwanyo phosphorus, ma obi medo dwong pa lum.

Gin marac ma bino pi kare malac me tic ki jami ma ki tiyo kwede me lwoko yugi ki dwoko piny kero me tic ki pii ma obale
Cweyo pii ma obale pe jenge i kom dano keken, ento bene jenge i kom jami tic.
Jami ma ki tiyo kwede me lwoko pii obedo ka lweny i dul ma anyim me yubu pii pi kare malac. Ka pe ki yubu ne kare ki kare, peko obi bino oyotoyot onyo lacen. Ento, pol kare, jami ma ki tiyo kwede me lwoko yugi pe kitwero yubu ne, pien ka jami mogo ocung, pii ma ki kato ki iye twero kato ma ki miito. I te cik me cul me nino ducu, dano weng pe twero culu ne.
I kin 467 ka gwoko pii ma ki tiyo kwede i boma ma lapwony Wang Hongchen otemo, ma romo aryo me adek gi tye ki rwom me tic pa pii ma kato 80%, ma romo acel me adek ma kato 120%, ki ka gwoko pii ma ki tiyo kwede 5 tye ma kato 150%.
Ka rwom me tic pa pii ni kato 80%, labongo kwanyo pii ma ki tiyo kwede ma dit, kabedo ma ki tiyo kwede me yubu pii ni pe twero juku pii ni pi gwoko ne pien ni pii ni oo i rwom ma opore, ki pe tye pii ma ki gwoko pi aerators ki secondary sedimentation tank suction ki scrapers. Jami ma tye piny ni ki twero yubu ne onyo loko ne ka pii otum woko.
Man tere ni, cokcok 2/3 pa ka gwoko pii maleng pe twero yubu jami ma ki tiyo kwede me neno ni pii ma ki tiyo kwede ni rwate ki cik.
Malube ki kwan pa lapwony Wang Hongchen, kwo pa aerators pol kare bedo mwaka 4-6, ento 1/4 pa jami ma ki tiyo kwede me kwanyo yamo pe gu timo tic me gwoko yamo i kom aerators pi kare ma romo mwaka 6. Gin ma ki lwongo ni mud scraper, ma mite ni ki kwany ki yubu, pol kare pe ki yubu mwaka weny.
Jami tic ni obedo ka tic ki two pi kare malac, ki kero me lwoko pii tye ka mede ki doko rac. Me cung matek i kom teko pa pii ma aa ki iye, yoo mo pe me juku ne pi gwoko ne. I kin jami marac ma kit meno, kare weny ki bi bedo ki jami ma ki tiyo kwede me juku pii ma obale ma obi rweny woko.
