Lwm Yam Siv

♦ Hauv kev lag luam yees duab los tiv thaiv cov kev daws teeb meem los ntawm oxidation.
Nws yog siv rau kev tsim cov roj hmab tshuaj thiab lwm yam kev siv tshuaj sib xyaw.
Nws siv tau rau lwm cov ntawv thov suav nrog kev muab tshuaj txhuam, roj rov qab, cov khoom noj, ua kom tuag, thiab xab npum.

Sodium Sulfide cov khoom muaj cov ntawv thov tseem ceeb tshaj plaws hauv cov khoom siv khoom siv rau qee cov khoom siv tshuaj, xws li cov neeg siv los kho cov kab mob ntawm daim tawv nqaij.

Cov Tshuaj Kho Mob thiab Tshuaj Kho Mob Los Kho Mob Siab Tus Kab.

Kev loj hlob ntawm cov qog hlwb kom tau tshaj tawm kev siv tshuaj kho mob.

Ib qho ntxiv, sodium sulphide Hoobkas feem ntau siv los ncua qhov pib ntawm hluav taws kub. Cov khoom siv yooj yim rau hlawv, thiab sodium sulphide Flake 1849 tuaj yeem ua rau lawv hlawv. Flammable comparcound, yog li txo qhov tshwm sim ntawm hluav taws kub ntawm 60% min kuj tseem siv tau los txhim kho cov nplaim hluav taws xob retardant cov khoom ntawm lub cev.

Kho thaum muaj xwm ceev ntawm to

Cais cais tawm cov toasticated cheeb tsam thiab teeb tsa cov cim ceeb toom nyob ib puag ncig nws. Cov neeg ua haujlwm thaum muaj xwm ceev yuav tsum tau hnav cov iav npog qhov ncauj qhov ntswg thiab cov khaub ncaws tiv thaiv tshuaj lom neeg. Tsis txhob hu ncaj qha rau cov ntaub ntawv xau. Zam plua plav, sau nws nrog daim ntaub huv huv hauv cov thawv qhuav, huv si thiab npog, thiab thauj nws rau lub vev xaib pov tseg. Koj tseem tuaj yeem yaug nws nrog cov dej ntau thiab muab cov dej ntxuav ua kom huv rau hauv cov dej khib nyiab. Thaum muaj kev sib tw loj, sau thiab rov qab siv nws lossis pov tseg ntawm nws tsis muaj kev phom sij.

Wastewater Txoj Kev

Cov dej khib nyiab uas ua rau sulfide viuring feem ntau yog alkaline dej khib nyiab, uas tuaj yeem cuam tshuam. Nyob rau hauv neutralization theem, tus pH txo thiab qee hydrogen sulfide yuav khiav mus rau hauv cov cua. Nyob rau tib lub sijhawm, cov tshuaj kub kub los ntawm cov tshuaj tiv thaiv nruab nrab tseem yuav ua kom cov tso tawm kev tso tawm ntawm hydrogen sulfide. Hydrogen sulfide yog tso tawm hauv cov khoom loj hauv huab cua, uas yuav ua rau cov huab cua ua kom muaj huab cua thiab cuam tshuam cov neeg. Txoj kev chlorination kuj tseem tuaj yeem tshem tawm cov pa roj sulfide, uas tseem yog ib txoj hauv kev zoo, tab sis nws yuav tsum tau ntau npaum li cas ntawm cov chlorine thiab yog kim. Tsis tas li ntawd, cov ntawv hlau lossis cov khoom siv hlau tsis muaj tshuaj lom (xws li hlau sulfate, hlau chloride, thiab lwm yam) tau ntxiv rau cov sulfide-paug quav dej. Tom qab 2 teev ntawm aeration, nquag hlau hydroxide yog tsim tawm, thiab sulfide tuaj yeem tshem tawm hauv daim ntawv ntawm cov hlau sulfide nag lossis daus. Cov dej khib nyiab nrog cov pa phem loj tuaj yeem ua kom muaj kev cuam tshuam los ntawm Flue roj ua ntej, thiab tom qab ntawd kho los ntawm kev ua haujlwm sludge txoj kev.
