Iziphumo zeCOD, ammonia nitrogen, phosphorus iyonke kunye nenitrogen iyonke kumgangatho wamanzi

I-COD, i-ammonia nitrogen, i-phosphorus iyonke kunye ne-nitrogen iyonke zezona zizalathisi eziphambili zongcoliseko kwimizila yamanzi.Impembelelo yabo kumgangatho wamanzi inokuhlalutywa kwiinkalo ezininzi.
Okokuqala, i-COD isalathisi somxholo wezinto eziphilayo emanzini, ezinokubonisa ukungcoliswa kwezinto eziphilayo kumzimba wamanzi.Amanzi anezigxina eziphezulu ze-COD athanda ukuba ne-turbidity ephezulu kunye nombala, kwaye athanda ukuzala iibhaktheriya, okukhokelela kubomi obufutshane bamanzi.Ukongeza, ukugxila okuphezulu kwe-COD kuya kusebenzisa ioksijini enyibilikisiweyo emanzini, okukhokelela kwi-hypoxia okanye ukufuthanisela kumzimba wamanzi, okubangela ukwenzakala kubomi basemanzini.
Okwesibini, i-ammonia nitrogen yenye yezondlo ezibalulekileyo emanzini, kodwa ukuba i-concentration ye-ammonia nitrogen iphezulu kakhulu, iya kukhokelela kwi-eutrophication yomzimba wamanzi kwaye ikhuthaze ukubunjwa kweentyantyambo ze-algae.I-algae blooms ayigcini nje ukwenza amanzi adibeneyo, kodwa iphinda idle isixa esikhulu se-oksijini enyibilikileyo, ekhokelela kwi-hypoxia emanzini.Kwiimeko ezinzima, kunokubangela inani elikhulu lokufa kweentlanzi.Ukongeza, ukugxila okuphezulu kwe-ammonia nitrogen kuya kuvelisa amavumba angathandekiyo, okuya kuba neziphumo ezibi kwindawo engqongileyo kunye nobomi babahlali.
Okwesithathu, i-phosphorus iyonke yinto ebalulekileyo yesondlo sesityalo, kodwa ukugxininiswa kwe-phosphorus epheleleyo kuya kukhuthaza ukukhula kwe-algae kunye nezinye izityalo zasemanzini, okukhokelela kwi-eutrophication yemithombo yamanzi kunye nokuvela kwe-algal blooms.Iintyatyambo ze-algal azenzi nje amanzi ukuba adideke kwaye abe nevumba elibi, kodwa zikwatya isixa esikhulu seoksijini enyibilikisiweyo kwaye zichaphazela isakhono sokuzihlambulula emanzini.Ukongeza, ezinye i-algae ezifana ne-cyanobacteria zinokuvelisa izinto ezinobuthi, ezibangela ingozi kwindawo engqongileyo kunye ne-ecosystems.
Okokugqibela, initrogen iyonke yenziwe nge-ammonia nitrogen, initrogen yenitrate kunye nenitrogen ephilayo, kwaye luphawu olubalulekileyo olubonisa iqondo lokungcoliseka kwezondlo emanzini.Isiqulatho senitrogen esiphezulu ngokugqithisileyo asiyi kukhuthaza nje ukusasazeka kwezityalo eziphila emanzini kunye nokuvela kweentyantyambo ze-algal, kodwa kuya kunciphisa ukungafihli kwemithombo yamanzi kwaye kuthintele ukukhula kwezinto eziphila emanzini.Ukongeza, umxholo wenitrogen ogqithisileyo uya kuchaphazela incasa kunye nencasa yomzimba wamanzi, echaphazela ukusela kunye nobomi babahlali.
Ukushwankathela, i-COD, i-ammonia nitrogen, i-phosphorus iyonke kunye ne-nitrogen epheleleyo zizibonakaliso ezibalulekileyo ezichaphazela umgangatho wamanzi, kwaye ukugxila kwabo okuphezulu kuya kuba nefuthe elibi kwimekobume yendalo yamanzi kunye nempilo.Ngoko ke, kubomi bemihla ngemihla kunye nemveliso, kufuneka someleze ukubeka iliso kunye nokulawulwa komgangatho wamanzi, sithathe amanyathelo asebenzayo okunciphisa ukukhutshwa kokungcola kwamanzi, kunye nokukhusela imithombo yamanzi kunye nokusingqongileyo kwendalo.
