Kuyeza kwa Ammonia mosalekeza mu Madzi a Mtsinje

Ubwino wa madzi a mitsinje umawunikidwa ndi bungwe la Environmental Agency kudzera mu pulogalamu ya General Quality Assessment (GQA) ndipo nkofunika kuti mankhwala omwe angakhale owopsa mumtsinjewo asamawulidwe. Ammonia ndi mchere wofunikira kwa zomera ndi algae zomwe zimakhala m'madzi a mitsinje. Komabe, kutentha kwa mtsinje kukasintha, ammonia a ionized amasintha kukhala mpweya wa ammonia womwe umakhala wopanda ionized. Izi ndizowopsa kwa nsomba ndi zamoyo zina zam'madzi mumtsinje, kotero ndikofunikira kuyang'anira kuchuluka kwa ammonia nthawi zonse.

Ubwino wa madzi ndiwonso wofunikira kwa malo opangira madzi omwe amagwiritsa ntchito madzi a mitsinje ngati magwero awo. Kuchuluka kwa ammonia m'madzi kungayambitse mavuto akulu pakupanga tizilombo toyambitsa matenda. Poyesa bwino milingo ya ammonia m'madzi amtsinje polowera malo opangira madzi, bungweli limatha kuteteza zolowera. M'mapulogalamu ena, choloweracho chimatha kutsekedwa pamene milingo ya ammonia ifika pamlingo wokwera kwambiri.

Njira zamakono zowunikira ammonia ndizokwera mtengo komanso zovuta, zimagwiritsa ntchito ma elekitirodi a ion-selective ndi ma reagents okwera mtengo, ndi oopsa komanso ovuta kuthana nawo. Oyang'anirawa nawonso sali achindunji ndipo amafuna kusamalitsa kosalekeza kuti agwirizane ndi zosowa zosiyanasiyana, monga kuyeretsa madzi onyansa, kuyeretsa madzi akumwa ndi kuyeza ammonia m'madzi amtsinje. Ma elekitirodi osankha ma ion nthawi zambiri amafunikira kuzimitsa tsiku ndi tsiku ndikuwongolera ndi ma reagents.

Chowunikira cha HONDE ammonia chimapewa zovuta zowunikira zachikhalidwe za ammonia pogwiritsa ntchito njira yapaderadera. Ammonia amasinthidwa kukhala gulu lokhazikika la monochloramine pamtunda wofanana ndi msinkhu wa ammonia woyambirira. Kuchuluka kwa chloramine kenako kuyeza pogwiritsa ntchito sensa ya polarographic membrane yokhala ndi kuyankha kotsatira kwa chloramine. Rection chemistry imapatsa wowunikirayo kukhudzika kwambiri ngakhale pamilingo yotsika kwambiri (ppb) ammonia.

Reagent ndi yosavuta, yotsika mtengo komanso yotsika mtengo. Choncho mtengo wa umwini ndi wotsika kwambiri.

Makampani akuluakulu amadzi ku UK ndi malo ovomerezeka ovomerezeka ndi Environment Agence akugwiritsa ntchito kale zowunikira za HONDE kuwunika bwino kuchuluka kwa ammonia m'madzi amtsinje. Dongosolo latsopanoli la ammonia lochokera ku Analytica Technologies limapatsa ogwiritsa ntchito chowunikira chomwe ndi chosavuta kugwiritsa ntchito, chopanda ndalama kugula, chotsika komanso chopanda kusokoneza muyeso.
