Falanqaynta suurtagalka ah ee dalabka ee daaweynta biyaha wasakhda ah
1. Hordhac aasaasi ah
Wasakheynta birta ee culus waxaa loola jeedaa wasakhowga bey'adda ee ay sababaan biraha culus ama xeryahooda. Inta badan waxaa keena sababaha aadanaha sida macdanta, qashinka gaaska, waraabinta bullaacadda iyo isticmaalka badeecadaha birta culus. Tusaale ahaan, cudurka cimilada biyaha iyo cudurka xanuunka ee Japan waxaa sababa wasakheynta meerkuri iyo wasakhoowga cad-cad. Heerka waxyeelada waxay kuxirantahay qaabka uruurinta iyo qaab kiimikaad ee birta culus ee deegaanka, cuntada iyo noolaha. Wasakheynta birta ee culus ayaa inta badan lagu muujiyaa wasakhowga biyaha, qaybna ka mid ah jawiga iyo qashinka adag.
Birta culus waxay tixraacaan biraha oo leh culeys gaar ah (cufnaanta) ka weyn 4 ama 5, oo waxaa jira tiro naxaas ah, zinc, zinc, zinc, vingsten, zinc, zinc, zinc, zinc, zinc, zinc, zinc, zinc, zinc, zinc, zinc) ay raadinayaan Waxyaabaha looga baahan yahay nashaadaadka nolosha, inta badan birta culus sida meerkurida, sunta rasaasta, iwm.
Biraha culus guud ahaan waxay ku jiraan dabiiciga ah ee uruurinta dabiiciga ah. Si kastaba ha noqotee, sababtuna tahay ka faa'iideysiga sii kordhaya, ka baaraandegida iyo wax soo saarka ganacsiga ee biraha culus ee bini-aadamka, maaddada culus sida hogaaminta, meerkurida, Cadmium, Garaac jawiga, iwm. Sababa wasakhowga deegaanka ee deegaanka. Birta culus ee gobollada kiimikada ee kala duwan ama foomamka kiimikada ayaa sii socon doona, uruursana oo u haajiraan ka dib markii aad gasho deegaanka ama deegaanka, oo sababa waxyeelo. Tusaale ahaan, biraha culus ayaa lagu soo saaray wasakhda wasakhda ah ee algae iyo dhoobada hoose xitaa haddii ay wax ku dhegan tahay dusha kalluunka iyo kalluunka qolofta leh, taasoo keentay wasakhowga silsiladda cuntada, taasoo keenta wasakheynta. Tusaale ahaan, unugyada biyaha ee Japan waxaa keena meerkurida biyaha qashinka laga soo saaray warshadaha wax soo saarka soogalootiga ee soodhada, kaas oo loo beddelay meerkuri dabiici ah iyada oo loo marayo ficil bayooloji ah; Tusaale kale waa xanuun, kaas oo sababay cadium-ka laga soo saaray warshadaha zeling shminc-ka iyo warshadaha korantada ee Cadmium-ka. Si. Hogaanka ka soo baxa qashinka gawaarida ayaa soo gala jawiga iyada oo kala-guurka jawiga ah iyo geedido kale, taasoo keentay koror aad u badan oo ku saabsan sunta rasaasta ee ku jirta 100 jeer ka sareeya tan aadanaha, iyo waxyeelada caafimaadka aadanaha.
Macromolecular heavy metal water treatment agent, a brown-red liquid polymer, can quickly interact with various heavy metal ions in wastewater at room temperature, such as Hg+, Cd2+, Cu2+, Pb2+, Mn2+, Ni2+, Zn2+, Cr3+, etc. It reacts to form water-insoluble integrated salts with a removal rate of over 99%. Habka daaweynta ayaa ku habboon oo sahlan, qiimuhu wuu yaraanayaa, saameyntu waa wax cajiib ah, xaddiga wasakhda ah, xasilloon, aan sun ahayn, oo ma jiro wasakhowga labaad. Waxaa si ballaaran looga isticmaali karaa daaweynta biyaha wasakhda ah ee warshadaha elektiroonigga ah, macdanta iyo gogosha, warshadaha ka baaraandegga birta, qashinka qashinka ee tamarta iyo warshadaha kale. Dheecaanka PH ee lagu dabaqi karo: 2-7.
2. Meesha arjiga badeecada
Iyada oo ah gebi ahaanba bir bir culus oo aad waxtar u leh, waxay leedahay codsiyo fara badan. Waxaa loo isticmaali karaa ku dhawaad dhammaan biyaha qashinka ee ay ku jiraan ion culus oo bir culus ah.
3. U adeegso habka iyo socodka caadiga ah ee socodka
1. Sida loo isticmaalo
1. Kudar oo walaaq
① Ku dar wakiilka daweynta birta polymer ee birta ee birta si toos ah iyada oo ay kujiraan wasakhda wasakhda ah ee birta ee birta ah, falcelinta isla markaaba, habka ugu fiican ayaa ah in la walaaqyo waqti kasta oo 10min-ah;
② Euros oo aan la taaban karin oo bir ah oo bir ah oo wasakh ah, tijaabooyin sheybaar ah waa in loo adeegsadaa go'aaminta xaddiga birta culus ee lagu daray.
In lagu daaweeyo wasakhda wasakhda ah ee leh ion culus oo leh uruurin kala duwan, xaddiga alaabta ceyriinka ah ayaa si otomaatig ah loogu xakamayn karaa Orp
2. Qalabka caadiga ah iyo geedi socodka teknolojiyada
1. Biyaha si aad u hesho biyaha 2 kaydka 10, shaandhada 121, xanta finalka ee ugu dambeeya ee PH-da barkadda 12, biyo dheecaan
4. Falanqaynta dheefaha dhaqaalaha
Qaadashada biyaha wasakhda ah ee wasakhda ah wasakhda bir culus oo caadi ah, oo ka mid ah warshadahaas oo keliya, shirkadaha codsiga ayaa gaari doona faa'iidooyin bulsho iyo dhaqaale oo waaweyn. Biyaha korantada ee korantada ayaa inta badan ka timaadda maydhashada biyaha yar ee qaybo yar iyo qadar yar oo dareere qashin ah. Nooca, waxa ku jira iyo qaabka birta culus ee wasakhda wasakhda ah waxay si weyn ugu kala duwan yihiin noocyo wax soo saar oo kala duwan, inta badan ay ku jiraan ion culus oo bir ah sida naxaas, zinc, zinc, zinc, zinc, iyo niktel. . Sida ku xusan tirakoobka aan dhameystirneyn, dheecaan sanadeedka wasakhda wasakhda ah ee warshadaha korantada ee korantada kaligiis ayaa ka sarreeya 400 milyan tan.
Daaweynta kiimikada ee biyaha korantada ee korantada waxaa loo aqoonsan yahay sida habka ugu waxtarka badan uguna macquulsan. Si kastaba ha noqotee, inaad ka xukunto natiijooyinka sanado badan, habka kiimikada ayaa leh dhibaatooyin ay ka mid yihiin hawlgal aan deganayn, wax ku oolnimada dhaqaalaha iyo saameynta deegaanka oo liidata. Wakiilka daweynta biyaha ee birta ee birta ee birta ah ayaa si fiican loo xaliyaa. Dhibaatada kor ku xusan.
4. Qiimaynta dhameystiran ee mashruuca
1. Waxay leedahay awood yar oo yareynta CRV, tirada pH ee yareynta CR "waa balaaran (2 ~ 6), badidoodna waa waxyar aashitada
Wasakhda ku darka leh waxay baabi'in kartaa baahida loo qabo in lagu daro aashitada.
2. Waa xoogga alkaline, qiimaha pH waa la kordhin karaa isla waqtigaas waa lagu dari karaa. When the pH reaches 7.0, Cr (VI), Cr3+, Cu2+, Ni2+, Zn2+, Fe2+, etc. can reach the standard, that is, heavy metals can be precipitated while reducing the price of VI. Biyaha la daweeyay ayaa si buuxda u buuxiya heerka dheecaanka heerka koowaad ee fasalka
3. Qiimaha jaban. Marka la barbar dhigo soodhiyamka dhaqameed-dhaqameedka Sulfide, qiimaha howsha waxaa lagu yareeyaa in ka badan RMB 0.1 halkii ton.
4. Xawaaraha ka baaraandegida waa dhakhso, mashruucan badbaadada bay'addana waa mid aad u hufan. Roobabku waa fududahay in la xalliyo, oo laba jibaar ah sida ugu dhakhsaha badan ee habka lime. Roobab isku mar ah oo f-, p043 wasakhda wasakhda ah
5. Qaddarka burburku waa yar yahay, kaliya kalabar habka roobka kiimikada ee kiimikada
6. Ma jiro wax wasakho sare oo birta culus ka dib daaweynta, iyo kiishadda aasaasiga ah ee naxaasta ah ee naxaasta ah waa fududahay in hyrololkuze;
7. Iyada oo aan xirmin maro shaandhada, si joogto ah ayaa loo socodsiin karaa
