Kuyeza kosalekeza kwa Ammonia m'madzi a mtsinje

Bungwe Loona za Zachilengedwe limayesa ubwino wa madzi a m'mtsinje kudzera mu pulogalamu ya General Quality Assessment (GQA) ndipo ndikofunikira kuti mankhwala omwe angakhale oopsa mumtsinje alamulidwe. Amoniya ndi michere yofunika kwambiri pa zomera ndi algae zomwe zimakhala m'madzi a m'mtsinje. Komabe, kutentha kwa mtsinje kukasintha, ammonia yomwe ili ndi ayoni imasintha kukhala mpweya wa ammonia womwe suli ndi ayoni. Izi ndi zakupha nsomba ndi zamoyo zina zam'madzi mumtsinje, choncho ndikofunikira kuyang'anira nthawi zonse kuchuluka kwa ammonia.

Ubwino wa madzi ndi wofunikanso kwa mafakitale oyeretsera madzi omwe amagwiritsa ntchito madzi a mumtsinje ngati gwero lawo. Kuchuluka kwa ammonia m'madzi kungayambitse mavuto akulu pa njira yoyeretsera. Poyesa bwino kuchuluka kwa ammonia m'madzi a mumtsinje pamalo olowera a fakitale yoyeretsera madzi, bungweli limatha kuteteza malo olowera. Nthawi zina, malo olowera amatha kutsekedwa pamene kuchuluka kwa ammonia kufika pamlingo wapamwamba kwambiri.

Njira zamakono zowunikira ammonia ndi zodula komanso zovuta, zimagwiritsa ntchito ma electrode osankha ma ion ndi ma reagent okwera mtengo, ndi oopsa komanso ovuta kuwagwiritsa ntchito. Ma monitor awa sali enieni ndipo amafunikira kuwunikira kosalekeza kuti agwirizane ndi zosowa zosiyanasiyana, monga kukonza madzi otayira, kukonza madzi akumwa komanso kuyeza kuchuluka kwa ammonia m'madzi a mtsinje. Ma electrode osankha ma ion nthawi zambiri amafunikira zeroing tsiku lililonse ndi kuwunikira ndi ma reagent.

Chowunikira cha ammonia cha HONDE chimapewa mavuto a zowunikira za ammonia zachikhalidwe pogwiritsa ntchito njira yapadera kwambiri. Ammonia imasinthidwa kukhala chophatikizana chokhazikika cha monochloramine pamlingo wofanana ndi mulingo woyambirira wa ammonia. Kuchuluka kwa chloramine kenako kunayesedwa pogwiritsa ntchito sensa ya polagraphic membrane yokhala ndi yankho losankha la linear ku chloramine. Mankhwala a reaction amapatsa chowunikiracho mphamvu yabwino kwambiri ngakhale pamlingo wotsika kwambiri (ppb) wa ammonia.

Reagent ndi yosavuta, mtengo wake ndi wotsika komanso mtengo wake ndi wochepa. Chifukwa chake mtengo wa umwini ndi wotsika kwambiri.

Makampani akuluakulu amadzi ku UK ndi ma laboratories ena ovomerezeka ndi Environment Agence akugwiritsa ntchito kale ma monitor a HONDE kuti azitha kuyang'anira bwino kuchuluka kwa ammonia m'madzi a m'mitsinje. Dongosolo latsopano la ammonia ili kuchokera ku Analytica Technologies limapatsa ogwiritsa ntchito ma monitor osavuta kugwiritsa ntchito, otsika mtengo kugula, otsika mtengo kugwira ntchito komanso opanda kusokonezedwa ndi kuyeza.
