Dhab ahaantii, waxaan ka qayb-galnay Shanghai IEexp- 24-aad ee Shiinaha International Environmental Expo.
Cinwaanka gaarka ah waa Shanghai New International Expo Center Hall N2 Booth No. L51.2023.4.19-23 waxaan halkan ku sugnaan doonaa, sugitaankaaga joogitaankaaga. Waxaan sidoo kale keennay xoogaa shaybaar ah halkan, iyo iibiyeyaasha xirfadlayaasha ah ayaa si faahfaahsan uga jawaabi doona dhibaatooyinkaaga daaweynta bulaacada si faahfaahsan waxayna bixiyaan xalal taxane ah.
Kuwa soo socda waa goobta dhacdada, kaalay oo naga hel!
Bandhigyadayada inta badan waxaa ka mid ah alaabada soo socota:
Midabaynta midabaynta oo tayo sare leh
CW taxane ah oo tayo sare leh decolorizing flocculant waa polymer cationic organic si madax-bannaan u horumariyo by our shirkadda in midaysa hawlaha kala duwan sida decolorization, flocculation, COD hoos u dhigista iyo BOD yaraynta. Caadi ahaan loo yaqaan dicyandiamide formaldehyde polycondensate.It waxaa inta badan loo isticmaalaa daaweynta biyaha wasakhda warshadaha sida, textile, daabacaadda, daabacaadda iyo dye. gawraca, caleenta qashinka lagu shubo, iwm.
Polyacrylamide
Kooxda amide ee polyacrylamide waxay noqon kartaa xiriir la leh walxo badan, qaab xayeysiis ah
Isku-xidhka hydrogen-ka, miisaanka molecular oo aad u sarreeya ee polyacrylamide ee ion-ka la isku dhejiyay
Qaybaha dhexdooda waxaa ka dhex abuurma buundada, flocculation ayaa la sameeyay, waxaana la dedejiyaa soo saarista qaybaha, markaas
gaadhaan yoolka ugu dambeeya ee kala-soocidda dareeraha adag.
Inta badan loo isticmaalo nadiifinta wasakhda, kala soocida dareeraha adag iyo dhaqidda dhuxusha, ka faa'iidaysiga iyo daaweynta biyaha wasakhda ah ee waraaqaha. Waxaa loo isticmaali karaa biyaha wasakhda ah ee warshadaha iyo daaweynta bulaacadaha gudaha ee magaalada. Waxaa loo isticmaali karaa warshadaha waraaqaha: hagaajinta qalalan iyo xoogga qoyan ee warqadda, wanaaji heerka haynta ee fiilooyinka wanaagsan iyo buuxinta. Waxa kale oo loo isticmaali karaa wax lagu daro alaabta dhoobada ah ee goobaha saliidda iyo qodista sahaminta juqraafiga.
polyaluminium chloride
Polyaluminum chloride waa nooc cusub oo waxtarka sare leh ee polymer-ka aan organic xinjirowga ahayn. Iyada oo ay ugu wacan tahay saamaynta isku xidhka ee ions hydroxide iyo polymerization of anions polyvalent, wakiilka daaweynta biyaha polymer-ka aan organic ee miisaanka molecular weyn iyo kharash koronto oo sarreeya ayaa la soo saaraa. .
Waxaa si weyn loogu isticmaalaa nadiifinta biyaha, daaweynta biyaha wasakhda, shubista saxda ah, samaynta waraaqaha, warshadaha isbitaalka iyo kiimikooyinka maalinlaha ah. Qiimaha wax-soo-saarka biyuhu waa 20% ilaa 80% ka hooseeya kuwa kale ee flocculant-ka ah. Waxay si dhakhso ah u samayn kartaa flocs, iyo ubaxa alum waa weyn yahay iyo xawaaraha sedimentation waa mid degdeg ah. Kala duwanaanshaha qiimaha pH ee ku habboon waa ballaadhan yahay (inta u dhaxaysa 5-9), iyo qiimaha pH iyo alkalinity ee biyaha la daweeyay ayaa hoos u dhacaya wax yar.
Badeecooyinka taxanaha ah ee ay soo saarto shirkadeena waxay leeyihiin miisaanyo kala duwan, kuwaas oo buuxin kara baahida codsiyada kala duwan. Flocculant-ka gaarka ah ee daaweynta biyaha dabada waxay leedahay miisaan ballaaran oo unugyo ah, way fududahay in la milmi karo, ku habboon tahay in lagu daro, oo si wax ku ool ah u shaqeeyo pH ballaaran.
Midabaynta flocculant si loo karsado biyaha wasakhda ah
Waqtigan xaadirka ah, habka daaweynta biyaha wasakhda ah ee coking caadiga ah waxay qabataa daaweynta biochemical, laakiin ay sabab u tahay joogitaanka walxaha organic refractory badan, COD ah, chromaticity, phenols kacsan, polycyclic hydrocarbons caraf udgoon, cyanide, batroolka, wadarta cyanide, nitrogen total, nitrogen ammonia, iwm Sida caadiga ah ma la kulmi karaan heerarka sare ee qiiqa biochemical ah ka dib markii daaweynta waa in aan la kulmi kara heerka sare ee daaweynta. kooxaha refractory, iyo saamaynta saarista inta badan laguma gaaro flocculants caadiga ah. Flocculant-ka midabaynta si gaar ah loogu isticmaalo in lagu karsado biyaha wasakhda ah waxay gaari kartaa natiijooyin fiican marka lagu daro kaarboon firfircoon.
