Tshem tawm rau cov hlau hnyav hauv Desulfurization khib nyiab dej

Exn -904 yog ib qho organic sulphur hnyav hlau tshem tawm tus neeg sawv cev tsim rau desulfurization system wantewater; -904} yuav siv tau ntawm chav tsev kub nrog cu {}},}}, hg 2+, lwm yam nyob rau hauv wastewater ntau yam ntawm cov roj av hnyav, thiab tom qab ntawd ntxiv rau kev tshem tawm cov tshuaj tua hluav taws xob sai sai Cov pa phem hnyav tuaj yeem kho tau nrog cov neeg siv hluav taws xob hnyav exn}}}

Raws li kev tshawb fawb thiab xyaum cov txiaj ntsig, exn -904} muaj peb qhov zoo pom tseeb: 1) Tsawg toxicity; 2) qhov kev tshem tawm ntawm cov hlau hnyav yog qhov zoo heev, tuaj yeem tshem tawm tag nrho cov hlau hnyav hauv cov hlau ions thiab cov chelates, nyob rau hauv ntau yam ntawm tau siv ncaj qha hauv cov phot. 3) Qhov tsim ntawm insoluble macromolecular peb-seem chelates, nyob rau hauv cov xwm txheej ntawm qhov kub thiab muaj zog dej ntws yog ruaj khov thiab yooj yim rau khom.

Qhov kev siv tshwj xeeb ntawm cov tshuaj yuav tsum tau txiav txim siab raws li cov txiaj ntsig ntawm kev sim pov hwm kev sim.

Cov dej hauv qab yuav tsum muaj ntau dua 2, thiab nws raug nquahu kom kho hauv ph {1}};

Exn -904 tuaj yeem ntxiv rov qab ncaj qha los yog diluted;

Qhov kev siv tshuaj ntau yog 10-100 ppm, qhov kev siv tshwj xeeb yog txiav txim siab los ntawm kev sim raws li cov dej zoo; Lub sijhawm tiv thaiv feem ntau yog 30min;
