Nqus nyiaj plating recycling tshuab

Cov cuab yeej siv rov qab siv dua suav nrog rov qab osmosis membrane lim, lub twj tso kua mis tswj lub siab, thiab lwm yam. Qhov kev ntxuav ntawm daim nyias nyias muaj lub tank dej huv thiab lub twj tso kua mis. Qhov no yog siv los ntxuav cov residual Zn (OH) 2 nag lossis daus ntawm daim nyias nyias thiab tiv thaiv cov membrane pores los ntawm kev thaiv.

Nqus nyiaj plated CPU

Neutralization cov tshuaj tiv thaiv thiab cov khoom sib cais ntawm cov kua dej yog qhov tseem ceeb ntawm tag nrho cov txheej txheem kho dej. Tsim nyog pH tswj kom ua Zn2 ntxiv rau daim ntawv Zn (OH)2 nag lossis daus, thiab ua tiav cov kua-kua sib cais yog tus yuam sij rau kev ua kom cov paug tawm mus txog tus qauv. Chav tsev no yog tsim los ntawm grille, regulating tank, neutralization cov tshuaj tiv thaiv sedimentation tank. Lub dosing system txais ib tug ntau-tsim integrated dosing khoom, uas yog tsim los ntawm dosing chim, meter thiab tswj system. Nws txais kev tswj tsis siv neeg thiab kev tswj xyuas phau ntawv. Txoj kev hloov pauv no tsis yog tsuas yog ua kom cov dej nag zoo tshaj plaws, tab sis kuj yog ib qho yooj yim rau kev khiav lag luam, yooj yim thiab yooj yim, thiab tuaj yeem hloov kho qhov koob tshuaj kom paub meej qhov tseeb ntawm cov koob tshuaj thiab tswj tus nqi pH ruaj khov. Cov tshuaj npaj Na (OH) yog nws tus kheej nqus mus rau hauv qhov nruab nrab cov tshuaj tiv thaiv sedimentation tank los ntawm lub tshuab nqa nqa. Txoj kev hloov pauv siv hauv kev kho cov yas electroplating cov dej khib nyiab yog qhov yooj yim hauv cov txheej txheem, yooj yim thiab hloov tau yooj yim hauv kev ua haujlwm, siv tau thiab kev lag luam, ruaj khov thiab txhim khu kev qha hauv effluent zoo, thiab qis hauv cov nqi khiav lag luam.

Qhov tseem ceeb ntawm lub tshuab nqus tsev nyiaj zinc plating

Lub hauv paus ntsiab lus ntawm zinc nyob rau hauv yas electroplating thiab metalworking khib nyiab yog electroplating los yog pickling dragging kua. Cov kab mob kis tau rov qab mus rau cov dej yaug los ntawm cov txheej txheem hlau yaug. Cov dej khib nyiab muaj ntau cov hydrochloric acid, hnyav hlau ions xws li zinc thiab tooj liab, thiab cov organic brighteners, uas yog tshuaj lom heev.

Qee qhov kuj muaj cov carcinogenic, teratogenic thiab mutagenic cov tshuaj lom neeg, uas ua rau muaj kev phom sij heev rau tib neeg.
