Umgangatho wesizwe waseTshayina we-polyaluminium chloride yi-GBT22627-2022

I. Imvelaphi neNdawo eMiselweyo

1.Ukukhululwa kunye nokuphunyezwa

Ikhutshwe yi-State Administration for Market Regulation ngo-Matshi 9, i-2022 kwaye iphunyezwe ngokusemthethweni ngo-Oktobha 1, i-2022, ithatha indawo yenguqulo endala ye-GB / T 22627-2014.

Ifanelekile Amanzi oShishino unikezelo, amanzi amdaka, ugutyulo kunye nemveliso yokucoca i-polyaluminium chloride (PAC) imveliso.

2.Iinjongo ezimiselweyo

Siza kumanyanisa iimfuno zomgangatho wemveliso, siqinise izikhombisi zokhuseleko njengesinyithi esinzima kunye ne-microorganisms, kwaye sikhuthaze umgangatho wo Unyango lwamanzi ishishini.

Ⅱ.Iimfuno ezingundoqo zobugcisa

Ukuhlelwa kwemveliso kunye nenkangeleko

Ulwelo: ulwelo olungenambala ukuya kumthubi omdaka ocacileyo; okuqinileyo: amasuntswana amhlophe ukuya kumthubi omdaka/umgubo, akukho maqhuma, akukho vumba.

Iimpawu eziphambili zokusebenza

Yongeza kwaye ulungise izikhombisi

Yongeza: ubuninzi (ulwelo), izinto zovavanyo lwe-ammonia nitrogen; ukuqinisa: umda wensimbi enzima (i-arsenic, i-lead, i-cadmium, njl.). Inkcazo yezinto eziluhlaza: ukuveliswa kwe-hydrochloric acid kufuneka kuhambelane ne-GB / T 320 umgangatho woshishino, ukuba usebenzisa inkunkuma enobungozi, imvume yokusingqongileyo iyafuneka. Yongeza: ubuninzi (ulwelo), izinto zovavanyo lwe-ammonia nitrogen; ukuqinisa: umda wensimbi enzima (i-arsenic, i-lead, i-cadmium, njl.). Inkcazo yezinto eziluhlaza: imveliso ye-hydrochloric acid kufuneka ihambelane ne-GB / T 320 umgangatho woshishino, ukuba usebenzisa inkunkuma enobungozi, imvume yokusingqongileyo kufuneka ifunyanwe.

Ⅲ.Indlela yovavanyo kunye noqinisekiso lomgangatho

1.Indlela ezininzi zokubhaqwa kwentsebenziswano

Umxholo weAlumina: titration; ubutyuwa: i-spectrophotometry; isinyithi esinzima: i-athom yokufunxa i-spectrometry.

Isalathiso semveliso engamanzi siya kubalwa ngokwexabiso lomda we-Al₂O₃ umxholo ≥ 10%.

2.Inkqubo yokulawula umgangatho

Amashishini kufuneka enze uhlolo lwefektri (i-alumina, idigri yesiseko setyuwa, i-pH, njl.) kunye nokuhlolwa okugcweleyo rhoqo.

Ⅳ.Ukupakishwa, ukugcinwa kunye nothutho kunye nemigaqo yokhuseleko

1. imfuneko yokupakisha

Ulwelo: ukutywinwa komgqomo we-polyethylene; okuqinileyo: ukupakishwa kabini (ifilimu ye-polyethylene yangaphakathi + isikhwama sangaphandle), ebonisa igama lemveliso, imodeli kunye nomhla wokuvelisa.

2. Ukugcinwa kunye neemeko zokuhamba

Gcina kude nokukhanya, umoya, indawo eyomileyo, kude nomthombo womlilo; Ubomi beshelufu yolwelo ziinyanga ezi-3, ziqinile iinyanga ezili-12.

Ⅴ.Umahluko kwimigangatho yamanzi okusela

• Ububanzi besicelo: I-GB / T 22627-2022 yeyonyango lwamanzi oshishino, ngelixa amanzi okusela asekhaya axhomekeke kwi-GB 15892-2020 engqongqo (umzekelo, umda we-arsenic ≤0001%).
• Ukwahluka kwesalathisi: Umxholo webakala lezoshishino i-Al₂O₃ (≥28%) iphantsi kunenqanaba lamanzi okusela (≥29%), kwaye umda weentsimbi ezinzima ukhululekile ngakumbi.

Vi. Ukubaluleka kokuphunyezwa kwemigangatho

1. Ukuphuculwa kweshishini

Ukuphelisa amandla okuvelisa umva, ukukhuthaza uphuhliso lobugcisa bePAC obusebenzayo nobungenabungozi kokusingqongileyo.

2. Isiqinisekiso somgangatho wamanzi

Lawula ngokungqongqo izinto ezinobungozi ukunciphisa umngcipheko wongcoliseko lwesibini.

3. Umgangatho wemarike

Yaphula iimveliso ezikumgangatho ophantsi kwaye ukhusele amalungelo kunye nomdla wabasebenzisi abasezantsi.

I-GB/T 22627-2022 iseka ibhenchmark yokuveliswa kunye nokusetyenziswa kwe-polyaluminium chloride ngokusebenzisa izibonakaliso zobugcisa besayensi kunye neenkqubo zokuvavanya ngokungqongqo, eziphawula ukuqhubela phambili okubonakalayo ekulungelelaniseni imigangatho yemichiza yonyango lwamanzi yaseChina kunye nemimiselo yamazwe ngamazwe. Amashishini kufuneka ahambelane nophuculo olusemgangathweni, andise iinkqubo zemveliso, kwaye akhuthaze ngokudibeneyo uphuhliso lwenkqubo yokucoca amanzi aluhlaza.
