Textile dyeing ua rau qee qhov nyuaj tshaj plaws kev lag luam effluent los kho: siab organic load, khaus xim, thiab ib tug khiav uas swings nrog txhua batch ntau lawm. Thaum lub tuam txhab South Asian dyeing tau tshaj tawm nws cov txheej txheem lom neeg, nws rov qab kho lub aeration tank nrogBio Block biofilm media- thiab mus txog90% COD tshem tawm ntawm tus nqi khiav haujlwm tsuas yog $ 0.32 / m³thoob plaws 600 m³ / d tsim muaj peev xwm. Qhov no yog li cas qhov kev txhim kho tau muab ob qho tib si ua raws thiab kev txuag nyiaj.
Qhov project Overview
Lub Hoobkas textile dyeing nyob rau sab qab teb Asia tsim cov dej khib nyiab loj nrog cov organic load thiab cov xim siab. Raws li kev nthuav dav, cov txheej txheem kev kho thawj zaug tau dhau los ua hydraulically thiab organically overloaded, ua rau tsis ruaj khov paug zoo thiab mounting ib puag ncig siab los ntawm lub zos regulator.
Ntau dua li rov tsim kho cov nroj tsuag, tus neeg teb xov tooj tau hloov kho cov theem lom neeg los ntawm kev qhia Bio Block media ncaj qha rau hauv lub tank aeration uas twb muaj lawm. Bio Block yog ib qho txuas nrog - loj hlob biofilm cab kuj uas muab qhov chaw tiv thaiv loj rau cov kab mob, tso cai rau cov nroj tsuag los txhawb kev kho mob hauv tib lub hneev taw thaum txo nqi kev khiav hauj lwm piv nrog cov pa activated sludge.
Dej Quantity & Dej Zoo
Kev tsim cov dej khib nyiab yog tsav los ntawm cov txheej txheem dyeing, ntxuav lub voj voog, thiab cov sijhawm tsim khoom, yog li ob qho tib si ntws thiab thauj khoom hloov pauv ib teev. Lub kaw lus yog li ntawd qhov loj me nrog qhov nruab nrab tsim hauv paus thiab lub ncov tshaj plaws uas absorbs batch peaks tsis poob kev kho mob.
| Flow Parameter | Tus nqi | Sau ntawv tsim |
| Nruab nrab ntws | 550 m³/d | Yam khoom txhua hnub load |
| Tsim muaj peev xwm | 600 m³/d | Nrog rau yav tom ntej expansion margin |
| Peak factor | 1.8–2.0 | Absorbs dye-batch tawm peaks |
Kev muaj txiaj ntsig zoo qhia txog cov xwm txheej ntawm textile dyeing effluent: siab chemical thiab biochemical oxygen xav tau, elevated suspended solids, thiab hnyav xim uas yuav tsum tau tawg ua ntej tso tawm.
| Parameter | Muaj hwj chim | Load tseem ceeb |
| COD | 800-1,000 mg / L | High organic load los ntawm dyes thiab sizing |
| BOD | 300-400 mg / L | Yooj yim biodegradable feem |
| SS | 250 mg/l | Fibers thiab suspended dyestuff |
| Xim | Siab | Pom tau nyob rau hauv effluent, regulator -sensitive |
| pH | 6–9 | Hauv kev kho mob lom |
Cov qauv tso tawm
Lub kaw lus tau tsim los ua kom tau raws li cov kev txwv hauv cheeb tsam, uas tau teeb tsa lub qab nthab nruj ntawm cov teeb meem organic thiab tshem tawm cov khib nyiab thaum xav tau qhov pom kev txo qis hauv cov xim.
| Tshem tawm Parameter | Txheem txwv |
| COD | < 100 mg/L |
| BOD | < 30 mg/L |
| SS | < 70 mg/L |
| Xim | Yuav tsum tau txo qhov tseem ceeb |
Txheej Txheem Flow
Cov dej khib nyiab ua ntej dhau los ntawm kev tshuaj ntsuam xyuas kom tshem tawm cov khoom loj thiab cov fibers uas tuaj yeem thaiv cov khoom siv hauv qab. Tom qab ntawd nws nkag mus rau hauv lub tank sib npaug, uas buffers ob qho tib si ntws thiab thauj khoom yog li cov theem lom tau txais cov khoom noj tsis tu ncua es tsis txhob poob siab los ntawm ib tus neeg cov dye batch.
Cov dej sib npaug ces ntws mus rau hauv Bio Block integrated biological tank, qhov twg peb lub tshuab ua haujlwm ua ke:
- Bio Block muab thaj chaw tiv thaiv loj loj uas txhawb nqa sai sai biofilm
- Cov biofilm txuas nrog degrades organic pollutants zoo, nrog rau cov xim - tsim cov tebchaw
- Aeration muab cov pa oxygen txaus kom ua kom cov biofilm lom neeg ua haujlwm
Cov dej kho tom qab ntawd nkag mus rau qhov kev qhia meej thib ob uas biofilm sloughing thiab biomass tawm, tom qab ntawd los ntawm kev tso tawm zaum kawg. Sludge yog ib feem rov ua dua tshiab los tswj cov khoom lag luam lom neeg, thiab cov sludge ntau dhau yog dewatered rau kev pov tseg - cov kwj deg uas tsawg dua li cov nroj tsuag siv cov sludge.
