Ammonia lom
Nitrogenous tebchaw muaj xws li ammonia, nitrites thiab nitrates, uas tshwm sim ib txwm nyob rau hauv ib tug biologically paub tab thiab thaum lub sij hawm nws "maturation". Poisoning tshwm sim thaum lub concentration ntawm ib qho ntawm cov tebchaw nce mus txog qhov muaj nqis siab heev.
Koj tuaj yeem txiav txim siab lawv siv cov kev sim tshwj xeeb (cov ntawv litmus lossis cov tshuaj reagents).
Qhov no tshwm sim rau ntau yam. Qhov no tej zaum yuav yog ib qho overabundance ntawm cov zaub mov, uas cov ntses tsis muaj sij hawm noj thiab nws pib decompose nyob rau hauv qab. Kev puas tsuaj ntawm cov lim dej lom neeg, vim qhov tshwm sim ntawm cov ammonia tsis muaj sij hawm los ua kom muaj kev nyab xeeb dua thiab pib sib sau. Cov txheej txheem tsis tiav ntawm lub voj voog nitrogen, thaum cov ntses tau muab tso rau hauv lub thoob dej yug ntses tsis paub qab hau thiab lwm yam laj thawj.
Cov tsos mob:
Muaj qhov muag ntawm lub qhov muag, cov ntses zoo li "suffocate" thiab nyiam nyob ze ntawm qhov chaw. Hauv cov xwm txheej zoo, kev puas tsuaj rau cov gills tshwm sim, lawv tig xim av thiab tsis tuaj yeem nqus oxygen.
Kev kho mob
Nws yog ib qho kev xav tsis zoo uas thaum muaj tshuaj lom nrog cov tshuaj nitrogenous, cov ntses yuav tsum tau hloov mus rau dej huv. Feem ntau qhov no tsuas yog aggravates qhov teeb meem, txij li cov ntses tuaj yeem tuag los ntawm kev hloov pauv hauv cov dej muaj pes tsawg leeg.
Ua ntej ntawm tag nrho cov, txiav txim siab qhov concentration ntawm cov compound yog tshaj siv cov kev ntsuam xyuas. Ua ib qho kev hloov dej ib nrab (30-40% ntawm ntim) nrog cov dej tshiab ntawm qhov kub thiab txias thiab hydrochemical muaj pes tsawg leeg (pH thiab GH). Ua kom aeration thiab ntxiv cov reagents uas neutralize cov tshuaj lom neeg. Reagents yog yuav los ntawm cov khw muag tsiaj lossis cov vev xaib tshwj xeeb. Nws raug nquahu kom yuav lawv ua ntej kom muaj teeb meem lawv ib txwm nyob ntawm tes - ib yam khoom pab thawj zaug rau lub thoob dej yug ntses.
