Tignoolajiyada midabaynta ee polymer iron sulfate (PFS) ee daabacaadda iyo midabaynta biyaha wasakhda ah

Faa'iidooyinka 1.Core ee tignoolajiyada decolorization sulfate birta polymeric

xinjirowga waxtarka leh iyo awoodda midabaynta ee polymer iron sulfate (PfsHydrolysis ee biyaha si ay u soo saaraan isku dhafan oo kala duwan (sida [Fe ₂ (OH) ₃] ³), iyada oo loo marayo dhexdhexaadinta kharashka, buundada adsorption iyo dabaylaha, ka saarida degdega ah ee walxaha kolloidalka ah iyo molecules dheeha milmaya ee daabacaadda iyo dheehidda biyaha wasakhda ah, iyo heerka midabaynta ee midabada firfircoon ee midabaynta iyo nacnaca ayaa gaadhay 9% dyes.

Marka laga soo tago midabaynta ka saarista wasakhowga ah ee laba geesoodka ah,Pfswaxay isku mar yareyn kartaa COD (heerka saarista in ka badan 80%) iyo wadarta fosfooraska. Katiinadaha birta hydroxide ee ay abuurto waxay jidh ahaan u nuugi karaan ayoonooyinka biraha culus iyo walxaha organic, waxayna xaqiijin karaan nadiifinta dhamaystiran ee biyaha wasakhda ah.

Marka la barbardhigo dhaqaalaha iyo badbaadada aluminium aluminium, PFS kuma jiraan khatarta haraaga aluminium, iyo qiimaha alaabta ceeriin waa yar yahay (ferrous sulfate sida alaabta ceeriin), iyo kharashka daaweynta waa 20% -50% ka hooseeya kan wakiilada dhaqameed.

2.Farsamaynta midabaynta iyo xuduudaha xakamaynta muhiimka ah

Mechanism of action-charges neutralization: PFS hydrolysis products with high positive charge, dhexda ka saara culayska taban ee dusha sare ee kolloid dheeha, iyo burburinta xasiloonida. oo ku jira molecule dheeha si loo beddelo milanka].

Xaaladaha ugu wanaagsan ee hawlgalka-pH kala duwan: 6-9 (xaaladaha acidic ayaa xannibaya hydrolysis, alkaline keenaysaa in failure of roobab ion birta) -Ku dar diiradda: sida caadiga ah 5% -20% khamriga hooyada waxaa lagu qasi jiray 0.2% -0.5% diiradda shaqada, taas oo ay fududahay in ay sabab u soo celinta midabka.- Xakamaynta heerkulka: wax ku ool ah gudahood 10-90 ℃

3.Engineering codsiga qodobbada muhiimka ah iyo xeeladaha tayaynta

Tiknoolajiyada daaweynta iskaashiga ah ee lagu daray PAM: 0.1-0.3 mg / L anionic polyacrylamide (PAM) waxay yareyn kartaa qadarka PFS 30% -50% waxayna kor u qaadi kartaa dejinta catkins.

Samee qaacidada kontoroolka halbeegyo badan leh: \ [C = 0.78T + 0.15pH-0.08 Temp \]

4.Falanqaynta kiisaska caadiga ah

Daaweynta biyaha wasakhda ee warshad daabacaadda iyo midabaynta (COD 2000 mg/L, 800 jeer)

Naqshadaynta habka: qaadashada isku dhafka PFS (50 mg / L) + anion PAM (0.2 mg / L), 200 r / min (1 min) + 80 r / min (15 min).

Saamaynta: COD dareeraha waa

5.Taxadarka hawlgalka

Xakamaynta kala-diridda-isticmaalka biyaha deionized ama isha biyaha wasakhaysan oo hooseeya, walaaqaya 5 daqiiqo si looga hortago isku-duubnida.- Iska ilaali taabashada tooska ah ee sulfide, haddii kale samaynta roobka sulfide ee birta madow waxay saameyn doontaa chromaticity, iyo lime waa in horay loogu daro si looga saaro sulfide.

Isku darka bamka cabbirka iyo qasiyaha taagan ayaa lagula talinayaa si loo hubiyo kala firdhinta isku midka ah ee wakiilka; Qaladka qalabaynta caadiga ah waa

Vi. Horumarka tignoolajiyada

Nidaamka qiyaasta qiyaasta caqliga leh wuxuu ku salaysan yahay nidaamka la socodka wakhtiga dhabta ah ee internetka ee Waxyaabaha, kaas oo si firfircoon u hagaajiya qiyaasta PFS iyada oo loo marayo mitirka turbidity iyo pH sensor, oo hoos u dhigaya isticmaalka daroogada 15% -30%.

Farsamada wax ka beddelka ee isku dhafan ee PFS waxaa lagu daraa nanomaterials (sida attite la beddelay) si loo hagaajiyo waxtarka xayeysiiska ee dheeh-dareenka.3. Habka diyaarinta cagaaran Samee tignoolajiyada diyaarinta saaxiibtinimo ee deegaanka sida habka oksaydhka hydrogen peroxide si loo yareeyo hadhaaga chlorate loona wanaajiyo nadiifnimada alaabta.

Soo jeedinta Codsiga: Biyaha wasakhda ah ee midabaynta midabka sare leh, waxa lagu talinayaa in la sameeyo tijaabada beaker si loo go'aamiyo jaangooyada duritaanka ugu fiican (20-100 mg/L), lana soco hadhaaga ion birta dareeraha ah (
