Kev txiav txim los ntawm cov ntaub ntawv muag khoom tsis ntev los no, tus naj npawb ntawm cov xaj tau txais los ntawm Liding Environmental Protection rau AAO cov txheej txheem cov cuab yeej tseem muaj siab. Dab tsi ua rau cov neeg siv khoom ntseeg tus txheej txheem no ntau dua? Tom ntej no, Liding Environmental Protection yuav qhia cov ntsiab lus ntawm AAO txheej txheem.
Lub hauv paus ntawm cov txheej txheem AAO yog siv cov nitrification thiab denitrification ntawm cov kab mob nyob rau hauv cov xwm txheej sib txawv kom ua tiav cov nitrogen tshem tawm, thiab siv cov kab mob phosphorus-accumulating kom tshem tawm phosphorus. Yog li ntawd, cov txheej txheem no yog tsim nyog rau tej yaam num nrog nruj tswj ntawm nitrogen thiab phosphorus pollutants. Lub luag haujlwm tseem ceeb ntawm cov khoom siv dej phwj hauv nroog nyob deb nroog ntawm cov txheej txheem AAO yog tsom rau hauv peb cov tshuaj tiv thaiv, uas yog lub pas dej anaerobic, pas dej anoxic thiab pas dej aerobic.
Hauv thaj chaw anaerobic, vim tias tsis muaj nitrate thiab oxygen hauv cov dej phwj tuaj ntawm cov khoom siv dej phwj hauv nroog, phosphorus accumulating cov kab mob khaws lub zog hauv phosphorus-accumulating compounds thiab tso tawm phosphate radicals tib lub sijhawm, thaum lwm cov kab mob hauv paus tsis ua haujlwm. . Nyob rau hauv no cov tshuaj tiv thaiv module Lwm cov kab mob tsis tshua muaj zog thiab nyuaj rau loj hlob. Cov tshuaj tiv thaiv anaerobic yog siv los txo COD thiab npaj rau kev tshem tawm phosphorus.
Hauv cov tshuaj tiv thaiv anoxic, cov dej phwj tuaj ntawm cov khoom siv dej phwj hauv nroog nyob deb nroog muaj qee yam ntawm nitrate tsis muaj oxygen, thiab cov kab mob denitrifying siv COD kom txo nitrate rau nitrogen, tso alkali, thiab tau txais lub zog rau kev loj hlob. Txo COD thiab nitrate nitrogen.
Lub aerobic cov tshuaj tiv thaiv module yog lub hauv paus ntsiab lus ntawm thaj chaw ntawm cov khoom siv dej phwj nyob deb nroog. Ntawm no, cov kab mob nitrifying oxidize ammonia nitrogen rau nitrate nitrogen, noj alkalinity thiab oxygen, PAOs nqus cov phosphorus ntau, siv lub zog hauv PHAs los ua ke polyphosphorus, thiab OHOs txuas ntxiv tshem COD, PAOs, OHOs, thiab cov kab mob nitrifying tag nrho. hauv cov txheej txheem no. Txo COD, ammonia nitrogen thiab phosphorus.
Los ntawm qhov kev xav tau ntawm cov dej phwj hauv nroog nyob deb nroog, kev xaiv cov txheej txheem dej phwj tuaj yuav tsum ua kom tau raws li qhov yuav tsum tau ua ntawm kev kho cov nplai, cov dej phwj tuaj, cov dej tsis zoo thiab cov dej tawm hauv lub cev. Nyob rau tib lub sijhawm, cov txheej txheem kho kom tsim nyog yuav tsum raug xaiv raws li cov yam ntxwv ntawm cov dej phwj hauv zos. Ntau qhov xwm txheej qhia tau tias AAO cov khoom siv dej phwj nyob deb nroog muaj kev hloov pauv tau zoo rau ntau hom haujlwm.
