Ni byorekyerezi ki eby‘okureeberera omutindo gw‘amaizi omu myanya y‘entuura y‘amaizi g‘okunywa?

Amaizi g’okunywa n’omusingi mukuru gw’entunguuka etarikuhwaho ey’endembo z’omurembe, kandi okuha abantu amaizi marungi, ageesigwa, kandi ag’amagara marungi n’omusingi gw’okutunguura entunguuka y’eby’entaasya n’eby’entaasya. Okucondooza aha Intaneeti aha nshonga z‘amaizi g‘okunywa ni kikuru munonga. Nitubaasa tuta kureeba ngu omutindo gw‘amaizi gwagumaho omu nshozi z‘amaizi? Nitubaasa kuhikiiriza tuta okucondooza aha mutindo gw‘amaizi omu nshozi z‘amaizi g‘okunywa aha Intaneeti omu bwire bw‘eshaaha 24 kandi hatariho kuteganisibwa?

Omu "Emiringo y'obuyonjo bw'amaizi g'okunywa" (GB5749-2022), nikigambwaho gye ngu omuyaga gwa klorini n'ebitebeekanisiibwe bya klorini ebya busha byakoresibwa nk'ebintu ebirikuzibira obukooko, omubaro gw'obuntu ogwa klorini ogusigaireho n' Koloriini yoona aha muheru gw’omutimbagano gw’emipiira tigurikuza kuba ahansi ya 0.05mg/L, omubaro gw’ekiriisa kya chlorine dioxide ogusigaireho tigurikuza kuba ahansi ya 0.02mg/L, obucupa tiburikurenga 1 NTU (omu mbeera z’omutaano tiburikurenga 5 NTU.), kandi pH eri ahansi ya 8 terikurenga 5 NTU.

(1) Chlorine esigaireho (okurugiirira aha mutindo gw‘obuyonjo gw‘amaizi g‘okunywa GB5749-2006, ekikomo kya klorini esigaireho ni: obwire bw‘okukoragana n‘amaizi ni ≥ edakiika 30, ekipimo omu maizi g‘ekyombeko ni 4mg/L; ekisigaireho omu maizi g‘ekyombeko ni ≥/0L the ≥si. amaizi aha muheru gw‘omutindo gw‘emipiira ni ≥ 0.05mg/L;).

(2) Ebirikworeka okuhurira kw‘amaizi, nk‘erangi, okuhinduka kw‘amaizi, ebintu ebirikureebeka n‘amaisho, okunuuka, n‘okushemererwa (ekikomo ky‘okuhinduka kw‘amaizi kya 1 NTU omu mutindo gw‘obuyonjo gw‘amaizi g‘okunywa GB5749-2006).

(3) Ebintu byona ebigumire ebishazirwe, ebifunziibwe nka TDS .

Okutwarwa kw’amaizi, okuri omu kugarukamu kw’okuzibira kwago amashanyarazi, nikukira kukoresibwa kworeka obushemeire bw’amaizi. Omutindo gw‘eihanga GB5749-2006 "Emiringo y‘obuyonjo bw‘amaizi g‘okunywa” gwine ekyetengo kikye aha bihingwa byona ebigumire (TDS) eby‘amaizi g‘okunywa g‘omu taapu: TDS ≤ 1000 mg/L, ekirikureebeka ngu kiri hare n‘omutindo gw‘ensi yoona. Ahabw’okutunguuka kw’amakorero, emiringo n’obungi bw’ebintu ebirikushiisha amaizi byeyongyeire, kandi omuhendo ogu nigubaasa kutagaruka kuhika aha mutindo gw’okunywa kw’abantu. Omuhendo gwa TDS ku gurikurenga 200, nigutwarwa nk’omutindo gw’amaizi g’amakorero, kandi amaizi agari ahaiguru ya 300 nigashiisha amakorero. Ni mihendo ki eya TDS ey‘emiringo y‘amaizi etari emwe n‘emwe? Omuhendo gwa TDS gw‘amaizi ga taapu niguhinduka omu bicweka bitarikushushana, n‘emihendo y‘ahaiguru omu bicweka by‘omu bukiizi-bwa-bumosho. Omuhendo gwa TDS gw’amaizi omu bimera by’amaizi omu bwijwire guri haihi 180-260. Ku kiraabe kiri amaizi g’ahansi y’ebiziba ebiri omunda munonga, gaine kuba gari ahaiguru, gari haihi 300. Omu myanya emwe, nikibaasika ngu amaizi g’ahansi y’itaka omu myanya y’amakorero nigabaasa n’okukiraho bwanyima y’okushiisha. Amaizi aga butoosha agarikushemezibwa omu tekinologiya ya reverse osmosis (RO) gari omu myaka 50, agarikubaasa kukoresibwa abantu.

(4) Omuhendo gwa pH: Okurugirira aha "Mutindo gw'obuyonjo bw'amaizi g'okunywa", omuhendo gwa pH gw'amaizi g'omu taapu guri ahagati ya 6.5 na 8.5. Amaizi againe asidi y’amaani nari alkalinity ti marungi aha mubiri gw’omuntu, n’ahabw’ekyo okucondooza aha muheendo gwa pH nakyo ni kikuru.
