Kev tsom xam ntawm Electroplating Cov txiaj ntsig rau hluav taws xob cua sov Tubes

Txoj haujlwm kho cov dej khib nyiab npog thaj tsam ntawm 250m2 thiab muaj cov txheej txheem compact. Cov nqi khiav haujlwm ntawm qhov project yog qhov tsawg, thiab cov nqi khiav haujlwm txhua hnub feem ntau suav nrog kev siv hluav taws xob, kev siv tshuaj lom neeg, thiab cov nqi zog. Lub zog tag nrho ntawm lub kaw lus yog 45kW, nrog rau kev siv hluav taws xob ntawm 126.32kWh / d, chav dej siv ntsuas ntawm 0.88kWh / m3, tus nqi ntawm {{10}} .8 yuan/kWh, thiab tus nqi zog ntawm 0.70 yuan/m3; Cov neeg ua haujlwm quota yog 4 tus neeg, tag nrho cov nqi ua haujlwm yog 4800 yuan / hli, thiab cov neeg ua haujlwm cov nyiaj hli yog 1.11 yuan / m3; Kev siv tshuaj suav nrog NaClO, NaOH, H2SO4, PAM, PAC, Ca (OH) 2, NaHSO3, thiab lwm yam, tag nrho 103.85 yuan / d, thiab cov nqi tshuaj yog 0.72 yuan / m3 (saib Table 4). Nyob rau hauv tag nrho, tus nqi khiav hauj lwm ntawm electroplating wastewater kho yog 2.53 yuan / m3.

Tus nqi khiav haujlwm ntawm kev kho dej rov siv dua yog 2. Reagent noj {{10}}.15 yuan/m3; Lub ntsiab lim dej yog siv rau 3 lub hlis ntawm tus nqi ntawm 0.09 yuan / m3; Activated carbon yog siv li ntawm ib nrab xyoo ntawm tus nqi ntawm 0.37 yuan / m3; Lub neej ua haujlwm ntawm RO yog 3 xyoos, 0.32 yuan / m3.

Cov kev kho mob dav dav ntawm cov txheej txheem tshuaj muaj xws li cov txheej txheem xws li oxidation-txo, neutralization nag lossis daus, thiab cov kua dej sib cais. Raws li cov hauv paus ntsiab lus ntawm kev sib cais ntawm cov dej huv thiab qias neeg thiab kev sib cais ntawm qhov zoo, cov txheej txheem tshuaj siv rau kev kho cov dej khib nyiab electroplating. Lub tshuab yog mature, cov nyhuv yog ruaj khov, thiab kev hloov kho rau kev tshem tawm cov pa phem hlau hnyav yog muaj zog. Vim lub sij hawm tsim kho thaum ntxov ntawm txoj haujlwm no, chromium uas muaj cov dej khib nyiab thiab npib tsib xee uas muaj cov dej khib nyiab los ntawm cov hlau hnyav tau raug kho ua ntej thiab tom qab ntawd sib tov rau kev kho mob hauv nruab nrab. Txawm hais tias qhov ntsuas dej tawm tau ua tau raws li cov qauv tsim nyog, nws tsis yog nyob rau hauv lub rooj cob qhia lossis cov chaw tsim khoom siv dej khib nyiab. Yog li ntawd, kev txhim kho ntxiv yog txiav txim siab thaum lub sij hawm tsim kho engineering kom ua tau raws li qhov yuav tsum tau muaj ntawm cov qauv tsim nyog thiab cov qauv tsim engineering.

Tsis siv neeg tswj cov tshuaj ua kom tiav chav kho rau electroplating dej khib nyiab. Lub kaw lus tsis siv neeg dosing tswj yog tswj los ntawm pH thiab ORP controllers los ntawm cov sensors los tswj cov koob tshuaj ntawm txhua chav ua haujlwm ntsuas twj, uas yooj yim rau kev khiav lag luam thiab txhim khu kev lag luam. Zam kev siv zog ua haujlwm siab ntawm phau ntawv siv tshuaj thiab kev tswj tsis raug ntawm kev noj ntau npaum li cas, ua rau kev siv tshuaj tsis txaus lossis kev siv pov tseg. Lub metering twj tso kua mis thiab ntsuas ntsuas tau txais cov khoom lag luam los ua kom muaj kev ntseeg siab ntawm kev ua haujlwm.

Electroplating wastewater yog tshuaj kho thiab muab faib rau rov siv dua los ntawm kev kho rov qab osmosis. Ib feem ntawm cov dej tso tawm tsim nyog yog siv rau kev kho qhov chaw ua ntej xws li kev ua haujlwm tu nrog cov dej tsis zoo. Qhov rov qab osmosis kev kho cov dej ntws rov qab siv dua rau chrome plating tu thiab chrome stripping tu, txo cov dej khib nyiab. Kev ua tiav thiab kev ua haujlwm ntawm qhov project yuav txo qis tag nrho cov pa phem hlau hnyav hauv electroplating dej khib nyiab thiab txhim kho cov dej rov qab siv dua.

Cov qauv tsim ntawm cov txheej txheem tshuaj tiv thaiv rau cyanide uas muaj cov dej khib nyiab thiab chromium uas muaj cov dej khib nyiab tau tsim nyog txuas ntxiv lub sijhawm nyob hauv cov tshuaj tiv thaiv, nrog rau lub sijhawm tshuaj tiv thaiv ntawm 30 feeb, kom ntseeg tau tias cov tshuaj tiv thaiv redox tau ua tiav thiab txhim kho cov nyhuv kho.

Kev khiav hauj lwm ib puag ncig ntawm electroplating wastewater kho engineering yog hnyav, thiab muaj cov kev xav tau siab rau cov khoom siv xaiv thiab tiv thaiv corrosion ntawm cov qauv. Cov dej khib nyiab nqa lub twj tso kua mis siv lub tshuab ua kom siab molecular hnyav polyethylene yas hauv ob sab phlu thiab hnav-resistant thiab corrosion-resistant centrifugal twj; Txhua lub tank cov tshuaj tiv thaiv yog nruab nrog cov agitator rau kev sib xyaw, siv cov khoom siv hlau tsis muaj steel; Cov qauv siv cov iav fiber ntau daim ntaub los tiv thaiv corrosion.

Cov dej khib nyiab hnyav muaj xws li kev kho ua ntej ntawm cyanide uas muaj cov dej khib nyiab, tooj liab pyrophosphate khib nyiab, chromium uas muaj cov dej khib nyiab, dej khib nyiab ua ntej, thiab lwm yam, thiab tom qab ntawd los nag hauv tib lub tank nrog cov tshuaj tiv thaiv alkali nag lossis daus thiab sedimentation tank. Yog li ntawd, lub generated electroplating nag lossis daus sludge tsis tau cais raws li hnyav hlau sludge, uas coj tej yam nyuaj rau sludge kho, pov tseg, thiab rov qab. Txawm li cas los xij, vim qhov tsawg ntawm cov dej khib nyiab hauv qhov project no, xws li kev faib cov sludge, sedimentation, thiab sau, nws ua rau muaj kev nqis peev ntau hauv engineering. Txoj kev txhim kho yog txhawm rau txhim kho qib kev tsim khoom huv si thiab nce qib rov qab ntawm Ni2 ntxiv thiab lwm yam hlau hauv cov kab ntau lawm.
