Deegaanka casriga ah, dhibaatooyinka bulaacada ee ay keento horumarinta warshadaha ayaa asal ahaan si habboon loogu daaweeyay gudaha iyo dibaddaba. Isagoo ka hadlaya tan, waa inaan xusnaa heerka midabaynta flocculants ee daaweynta biyaha. Asal ahaan, bulaacada ay soo saaraan warshado badan waxay u baahan yihiin inay isticmaalaan flocculants midabaynta. Yixing Cleanwater waxay ku bari doontaa aqoonta la xidhiidha iyo codsiyada dhinacyo kala duwan.
Noocyo kala duwan oo polymer-ka-soo-saarka flocculants ayaa si ballaaran loogu isticmaalaa beerta biyaha warshadaha iyo daaweynta wasakhda dibadda, kuwaas oo polyacrylamide (PAM) uu yahay nooca ugu weyn ee midabaynta flocculant. Marka la barbar dhigo flocculants cusbada inorganic dhaqameed, PAM, sida nooc cusub oo ah wakiilka daaweynta biyaha, waxay leedahay faa'iidooyin badan: fudud oo fudud in la isticmaalo, saamaynta flocculation waa daraasiin jeer ka badan cusbo inorganic dhaqameed flocculants; xawaaraha qulqulka degdega ah iyo xawaaraha sedimentation, hufnaanta dhoobada dhoobada sare; saamaynta daaweynta gaarka ah ee bulaacadaha qaarkood; qalab fudud ayaa loo baahan yahay, raad yar; kharashka daaweynta hoose; bulaacada dib ayaa loo warshadayn karaa oo dib loo isticmaali karaa, iwm.
CodsigaPAM midab ka dhigaya flocculant qaybaha kala duwan ee codsiga:
1. Codsiga warshadaha waraaqaha
Isticmaalka PAM ee miisaanka kellika ah ee midabaynta midabaynta waxay kordhin kartaa heerka roobabka ee midabada iyo walxaha kale ee ku jira biyaha cad waxayna yareeyaan khasaarahooda. Ku darida 0.25 ~ 0.5% PAM ee saxarka waxay kordhin kartaa heerka sedimentation ee saxarka by 40 ~ 80 jeer, la yareeyo content adag ee biyaha cad ilaa 66%, kordhiyo content dambaska ee warqad, kordhiyo heerka haynta ee pigments sida dhoobo cad by 8 ~ 18%, iyo badbaadin 20kg saxarka per ton warqad. Waxaa intaa dheer, ka dib markaad isticmaasho PAM, qulqulka biyaha cad ayaa si weyn loo dhimay, hoos u dhigaya wasakheynta deegaanka. Tusaale ahaan, adkaha la hakiyey ee biyaha wasakhda ah ee saxarka cad ee caanaha leh pH=6.8 waa 3000ppm. Ka dib markii lagu daaweeyay PAM oo leh heerka hydrolysis ee 5 ~ 10%, miisaanka molecular ee 5.5 ~ 10 million, iyo 500ppm ee aluminium sulfate, biyaha cad waxaa loo rogi karaa dareere aan midab lahayn oo hufan, iyo adkaha la hakiyey ayaa hoos loo dhigayaa 50ppm.
2. Codsiga midabaynta flocculants ee daaweynta biyaha
①Ka-hortagga qolof-qaadista iyo dhimista
Biyaha warshadaha iyo nadiifinta bulaacadaha, biyaha ceeriin waa in marka hore la caddeeyo. PAM midabaynta flocculants iyo xinjirowga aan dabiiciga ahayn ayaa inta badan loo isticmaalaa isku-dhafka, taas oo si weyn u yareyn karta isticmaalka xinjirowga aan dabiiciga ahayn, ka fogaanshaha xannibaadda qalabka iyo daxalka sababtoo ah isticmaalka xad-dhaafka ah ee xinjirowga aan dabiiciga ahayn, kana hortagaya samaynta miisaanka. Qaybaha 37.5 ee PAM oo leh miisaan kelli ah oo ka hooseeya 1 milyan iyo 50 qaybood oo sodium tripolyphosphate ah ayaa loo isticmaalaa si ay u sameeyaan miisaan xad-dhaaf ah, taas oo asal ahaan ka hortagi karta miisaanka kulaylka aadka loo qiyaasay.
②Daaweynta bulaacada warshadaha
3. Codsiga midabaynta flocculants ee daaweynta biyaha wasakhda ah ee warshadaha sonkorta
Casiirka sonkorta leh ee ay saxafada ka soo saaraan warshadaha sonkortu inta badan waa turbid oo ka kooban yahay sidoo kale aad u adag. Si loo helo casiir sonkor ah oo nadiif ah, waxaa loo baahan yahay in lagu daro caddeeyayaasha kiimikada. Waagii hore, flocculants-ka-midab-soo-saarka aan-organic-ka ayaa inta badan la isticmaali jiray, laakiin marka la horumariyo warshadaha sonkorta, flocculant-ka-soo-saarka aan-organic-ka ma dabooli karo baahida wax-soo-saarka. Sanadihii la soo dhaafay, codsiga PAM ee warshadaha sonkorta waxay kordhin kartaa heerka sedimentation by 20 jeer.
Marka la soo koobo, marka aan doorano polyacrylamide PAM decolorization flocculant iyadoo loo eegayo xaaladda dhabta ah, waa inaan u dooranaa iyadoo loo eegayo xaaladaha iyo xaaladaha kala duwan ee codsiga. Sidaa darteed, xulashada polyacrylamide sidoo kale waa mid aad muhiim u ah.
