Tag nrho qhov hluav taws xob tso dej phwj tuaj tiag tiag tshaj tus qauv

Lub qhov hluav taws xob tseem ceeb txuas nrog rau qhov chaw kho mob, thaum cov dej phwj hauv tsev, cov dej khib nyiab oily, cov dej khib nyiab emulsified, acid-base wastewater, cov dej khib nyiab hnyav, thiab lwm cov kwj sib xyaw yog tawm mus rau hauv qhov hluav taws xob. Qhov sib xyaw ntawm cov dej phwj tuaj ntawm lub qhov hluav taws xob tseem ceeb yog qhov nyuaj, thiab cov khoom thauj loj dhau, ua rau cov pa paug ntau dhau xws li roj av, COD, thiab cov hlau hnyav. Sau npe 1 ntawm qhov chaw kuaj xyuas ntawm hom thiab cov xwm txheej ntawm cov dej khib nyiab los ntawm cov tuam txhab electroplating

2.1 Tsim cov tswv yim thiab txheej txheem ntws

Raws li lub tuam txhab commission, lub plating tov dej khib nyiab yog kho siv cov txheej txheem qhia nyob rau hauv daim duab 1. Txhua yam ntawm cov pa phem yuav tsum xub muab ntxuav thiab kho cais los ntawm cov kav dej sib txawv. Txhua yam ntawm cov pa phem yuav tsum xub muab cais los ntawm cov kav dej huv thiab cov kav dej phwj tuaj. Cyanide yog kho los ntawm acidification thiab aeration gas txoj kev; Organic compounds xws li roj paraffin thiab surfactants yog emulsified, ntab, thiab sib cais.
