Haa! Shanghai! Waxaan joognaa halkan!

Dhab ahaantii, waxaan ka qayb-galnay Shanghai IEexp- 24-aad ee Shiinaha International Environmental Expo.

Cinwaanka gaarka ah waa Shanghai New International Expo Centre 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 iyo soo bandhig 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 waxtarka sare leh

CW taxanaha waxtarka sare leh ee midabaynta flocculant waa polymer cationic organic si madax banaan ay u horumarisay shirkadeena taas oo isku daraya shaqooyin kala duwan sida midabaynta, flocculation, dhimista COD iyo dhimista BOD. Caadi ahaan loo yaqaan dicyandiamide formaldehyde polycondensate.It waxaa inta badan loo isticmaalaa daaweynta biyaha wasakhda ah ee warshadaha. sida dharka, daabacaadda iyo midabaynta, waraaqaha samaynta, midabaynta, macdanta, khad, gawraca, caleenta qashinka, 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, hagaajinta 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 caadiga ah waxay qabataa daaweynta biochemical, laakiin sababtoo ah joogitaanka walxaha dabiiciga ah ee badan, COD, chromaticity, phenols kacsan, hydrocarbons polycyclic aromatic, cyanide, petroleum, wadarta cyanide, wadarta nitrogen, nitrogen ammonia, iwm. Sida caadiga ah ma la kulmi karaan heerarka qiiqa qaranka, sidaa darteed in daawaynta sare ka dib habka biochemical, waa in aan diiradda saara saarista 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.
