COD, ammonia nitrogen, tag nrho phosphorus thiab tag nrho cov nitrogen yog ib qho kev ua paug loj hauv cov dej.Lawv qhov cuam tshuam rau dej zoo tuaj yeem txheeb xyuas los ntawm ntau yam.
Ua ntej tshaj plaws, COD yog qhov qhia txog cov ntsiab lus ntawm cov organic teeb meem hauv dej, uas tuaj yeem cuam tshuam cov pa phem ntawm cov organic hauv lub cev dej.Cov dej hauv dej uas muaj cov COD ntau ntau yuav muaj cov turbidity thiab xim, thiab nws nquag ua rau cov kab mob, ua rau lub neej luv luv.Tsis tas li ntawd, cov ntsiab lus siab ntawm COD tseem yuav haus cov pa oxygen hauv dej, ua rau hypoxia lossis txawm tias ua tsis taus pa hauv lub cev dej, ua rau muaj kev phom sij rau cov dej hauv dej.
Qhov thib ob, ammonia nitrogen yog ib qho tseem ceeb ntawm cov as-ham hauv dej, tab sis yog tias qhov concentration ntawm ammonia nitrogen siab dhau lawm, nws yuav ua rau eutrophization ntawm lub cev dej thiab txhawb kev tsim cov algae blooms.Algae blooms tsis tsuas yog ua rau cov dej turbid, tab sis kuj siv ntau cov pa oxygen yaj, ua rau hypoxia hauv dej.Nyob rau hauv cov xwm txheej hnyav, nws yuav ua rau coob tus ntses tuag.Tsis tas li ntawd, cov ntsiab lus siab ntawm ammonia nitrogen yuav tsim cov ntxhiab tsw tsis zoo, uas yuav muaj kev cuam tshuam tsis zoo rau ib puag ncig thiab cov neeg nyob hauv lub neej.
Thib peb, tag nrho phosphorus yog ib qho tseem ceeb ntawm cov nroj tsuag cov zaub mov, tab sis ntau tshaj tag nrho cov phosphorus concentration yuav txhawb txoj kev loj hlob ntawm algae thiab lwm yam dej nroj tsuag, ua rau eutrophication ntawm dej lub cev thiab tshwm sim ntawm algal blooms.Algal blooms tsis tsuas yog ua rau cov dej turbid thiab tsw, tab sis kuj haus ib tug loj npaum li cas ntawm yaj oxygen thiab cuam tshuam rau tus kheej-purification muaj peev xwm ntawm cov dej.Tsis tas li ntawd, qee cov algae xws li cyanobacteria tuaj yeem tsim cov tshuaj lom, ua rau muaj kev puas tsuaj rau ib puag ncig thiab ecosystems.
Thaum kawg, tag nrho cov nitrogen yog tsim los ntawm ammonia nitrogen, nitrate nitrogen thiab organic nitrogen, thiab yog ib qho tseem ceeb qhia txog qhov muaj kuab paug hauv dej.Tag nrho cov ntsiab lus nitrogen ntau dhau yuav tsis tsuas yog txhawb nqa eutrophication ntawm lub cev dej thiab tsim cov algal blooms, tab sis kuj txo cov pob tshab ntawm lub cev dej thiab inhibit qhov kev loj hlob ntawm cov kab mob hauv dej.Tsis tas li ntawd, cov ntsiab lus nitrogen ntau dhau yuav cuam tshuam rau qhov tsw thiab saj ntawm lub cev dej, cuam tshuam rau cov neeg nyob hauv dej haus thiab lub neej.
Piv txwv li, COD, ammonia nitrogen, tag nrho phosphorus thiab tag nrho cov nitrogen yog cov cim tseem ceeb uas cuam tshuam rau cov dej zoo, thiab lawv cov concentrations siab yuav muaj kev cuam tshuam tsis zoo rau cov dej ecological thiab kev noj qab haus huv.Yog li ntawd, nyob rau hauv lub neej txhua hnub thiab kev tsim khoom, peb yuav tsum ntxiv dag zog rau kev saib xyuas thiab kev tswj xyuas dej kom zoo, siv cov kev ntsuas zoo los txo cov dej paug paug tawm, thiab tiv thaiv cov peev txheej dej thiab ecological ib puag ncig.
