Mining Wastewater Treatment Solutions nrog AdvancedPolyacrylamideFlocculation Technology

Nrog rau lub ntiaj teb no kev loj hlob ntawm mining kev lag luam, kev kho cov dej khib nyiab generated thaum lub sij hawm mining ntau lawm attracted zuj zus. Ntau hom mines-xws li tooj liab, thee, kub, thiab polymetallic mines- nthuav tawm cov dej khib nyiab sib txawv, thiab yog li tsis tuaj yeem siv cov txheej txheem kho zoo ib yam.

ECOLINK TECHNOLOGY tsom mus rau cov tshuaj kho dej hauv kev lag luam thiab cov kev daws teeb meem hauv dej, muab ib qho - nres cov kev pabcuam suav nrog flocculants, tshuaj kho dej, thiab cov khoom siv kho dej khib nyiab rau cov mines, cov chaw ua haujlwm ntxhia, thiab cov chaw lag luam. Los ntawm kev tsim cov txheej txheem tsim, peb pab cov neeg siv khoom txo qis cov nqi pov tseg thiab nce tus nqi ntawm cov dej rov siv dua thiab rov siv dua.

I. Lub ntsiab qhov chaw thiab cov yam ntxwv muaj kuab paug ntawm cov dej khib nyiab

Lub hauv paus ntsiab lus ntawm mining dej khib nyiab muaj xws li:

Qhov dej ntws:Cov dej hauv av thiab cov dej khib nyiab ntau lawm uas sib sau ua ke hauv lub sijhawm qhib - qhov chaw lossis hauv av mining.

Tailings Pond Rov Qab Dej:Cov dej khib nyiab uas muaj cov ntsiab lus siab ntawm cov khoom tsim tawm thaum lub sij hawm ore crushing, sib tsoo, thiab ntxhia ua.
