Ib qho khoom siv los ntawm cov chaw kho dej phwj yog tsim cov khoom pov tseg uas muaj ntau yam muaj kuab paug. Txawm tias chlorinated recycled dej tuaj yeem muaj cov tshuaj tua kab mob xws li trihalomethane thiab haloacetic acid. Cov khoom seem ntawm cov dej phwj tuaj kho, hu ua biosolids, muaj cov chiv ntau, tab sis tuaj yeem muaj cov hlau hnyav thiab cov khoom siv hluavtaws uas muaj nyob hauv cov khoom siv hauv tsev.
Kev lag luam tshuaj lom neeg ntsib teeb meem kev tswj hwm ib puag ncig hauv kev kho nws cov dej khib nyiab. Cov pa phem tawm los ntawm cov roj av refineries thiab cov nroj tsuag petrochemical suav nrog cov pa phem xws li cov roj thiab cov rog thiab cov khib nyiab tshem tawm, nrog rau ammonia, chromium, phenol thiab sulfides.
Lub zog cog
Fossil fuel power stations, tshwj xeeb tshaj yog cov thee-fired ones, yog ib qhov chaw loj ntawm cov dej khib nyiab. Ntau ntawm cov nroj tsuag no tso cov dej khib nyiab uas muaj cov hlau loj xws li txhuas, mercury, cadmium thiab chromium, nrog rau arsenic, selenium thiab nitrogen tebchaw (nitrates thiab nitrites). Cov nroj tsuag nrog kev tswj hwm huab cua, xws li cov ntaub ntub dej, feem ntau hloov cov pa phem mus rau hauv cov dej khib nyiab.
Hlau / hlau ntau lawm
Cov dej siv hauv kev tsim steel yog siv los ua kom txias thiab sib cais los ntawm cov khoom. Nws kis tau cov khoom xws li ammonia thiab cyanide thaum lub sij hawm pib hloov dua siab tshiab. Cov dej khib nyiab muaj xws li benzene, naphthalene, anthracene, phenol thiab cresol. Kev tsim cov hlau thiab hlau rau hauv daim hlau, xaim, lossis cov tuav yuav tsum tau dej ua lub hauv paus roj nplua nyeem thiab cov khoom ua kom txias, nrog rau cov kua dej hydraulic, butter, thiab cov khib nyiab. Dej rau galvanized steel yuav tsum tau hydrochloric thiab sulfuric acid. Cov dej khib nyiab muaj cov kua qaub yaug dej thiab cov kua qaub pov tseg. Feem ntau ntawm cov kev lag luam steel cov dej khib nyiab muaj paug nrog cov kua dej hydraulic, tseem hu ua cov roj soluble.
Hlau ua cov nroj tsuag
Cov khib nyiab los ntawm cov hlau ua tiav feem ntau yog av nkos (silt) uas muaj cov hlau yaj hauv cov kua. Hlau plating, hlau xov thiab luam ntawv Circuit Court board (PCB) kev lag luam tsim ua kom muaj ntau ntawm cov av uas muaj hlau hydroxides xws li ferric hydroxide, magnesium hydroxide, nickel hydroxide, zinc hydroxide, tooj liab hydroxide thiab txhuas hydroxide. Hlau tiav cov dej khib nyiab yuav tsum tau kho kom ua raws li tag nrho cov kev cai siv vim muaj kev cuam tshuam ib puag ncig thiab tib neeg / tsiaj txhu ntawm cov pov tseg no.
Lub tshuab ntxhua khaub ncaws
Kev lag luam kev lag luam textile kev lag luam cuam tshuam nrog ntau cov khaub ncaws txhua xyoo, thiab cov khaub ncaws, phuam da dej, hauv pem teb MATS, thiab lwm yam, tsim cov dej khib nyiab uas muaj roj, wadding, xuab zeb, grit, hnyav hlau, thiab cov organic tebchaw uas yuav tsum tau kho. ua ntej tso tawm.
Kev lag luam mining
Cov pob zeb hauv av yog cov dej sib xyaw thiab cov pob zeb zoo nkauj uas tau tso tseg los ntawm kev tshem tawm cov ntxhia hauv cov ntsiab lus xws li kub lossis nyiaj, thaum lub sijhawm ua haujlwm mining. Kev pov tseg zoo ntawm kuv cov tailings yog qhov nyuaj rau cov tuam txhab mining. Tailings yog ib qho kev lav phib xaub rau ib puag ncig nrog rau kev sib tw nqi tseem ceeb thiab lub sijhawm los txo cov nqi tsheb thauj mus los thiab pov tseg. Kev kho kom zoo tuaj yeem tshem tawm qhov xav tau ntawm tailings pas dej.
Roj thiab roj fracking
Cov dej khib nyiab los ntawm shale gas drilling yog suav tias yog cov khib nyiab pov tseg thiab yog saline heev. Tsis tas li ntawd, cov dej sib xyaw nrog cov tshuaj muaj nyob rau hauv kev txhaj tshuaj Wells los pab txhawb kev drilling muaj cov ntsiab lus siab ntawm sodium, magnesium, hlau, barium, strontium, manganese, methanol, chlorine, sulfate thiab lwm yam tshuaj. Thaum lub sij hawm drilling, ib txwm tshwm sim cov khoom siv hluav taws xob rov qab mus rau saum npoo nrog rau cov dej. Fracking dej kuj tseem muaj cov hydrocarbons, nrog rau cov co toxins xws li benzene, toluene, ethylbenzene thiab xylene uas tuaj yeem tso tawm thaum lub sijhawm drilling.
Kev ua zaub mov
Kev sib xyaw ntawm cov tshuaj tua kab, tshuaj tua kab, tsiaj pov tseg thiab cov chiv hauv cov zaub mov thiab dej khib nyiab txhua yam yuav tsum tau tswj hwm. Nyob rau hauv cov txheej txheem ntawm kev ua zaub mov los ntawm raw cov ntaub ntawv, cov dej lub cev muaj ib tug siab load ntawm cov khoom thiab soluble organic teeb meem runoff los yog tshuaj. Organic pov tseg los ntawm kev tua tsiaj thiab kev ua haujlwm, kua dej hauv lub cev, plab hnyuv thiab ntshav yog txhua qhov chaw ntawm cov dej paug uas yuav tsum tau kho.
