Ho etsa lik'hemik'hale
Indasteri ea lik'hemik'hale e tobane le mathata a bohlokoa a taolo ea tikoloho kaho hloekisa metsi a eona a litšilaphokotso. Lintho tse silafatsang tse fetisoang ke libaka tse hloekisang peterole le limela tsa petrochemical li kenyelletsa litšila tse tloaelehileng tse kang oli le mafura le lintho tse tiileng tse emisitsoeng, hammoho le ammonia, chromium, phenol le sulfide.
Setsi sa motlakase
Liteishene tsa matla a mashala, haholo-holo tse fehloang ka mashala, ke mohloli o moholo oametsi a litšila a indasteri. Bongata ba limela tsena li ntša metsi a litšila a nang le litšepe tse ngata tse kang loto, mercury, cadmium le chromium, hammoho le metsoako ea arsenic, selenium le nitrogen (nitrate le nitrites). Limela tse nang le taolo ea tšilafalo ea moea, joalo ka li-wet scrubbers, hangata li fetisetsa litšila tse hapiloeng ka har'a melapo ea metsi a litšila.
Tlhahiso ea tšepe / tšepe
Metsi a sebelisoang tlhahisong ea tšepe a sebelisetsoa ho pholisa le karohano ea lihlahisoa. E silafalitsoe ke lihlahisoa tse kang ammonia le cyanide nakong ea ts'ebetso ea pele ea phetoho. Molapo oa litšila o kenyelletsa benzene, naphthalene, anthracene, phenol le cresol. Ho etsa tšepe le tšepe ka lipoleiti, lithapo, kapa litšepe ho hloka metsi e le setlolo le se pholisang, hammoho le mokelikeli oa haeteroliki, botoro le lintho tse thata tse granular. Metsi bakeng sa tšepe ea galvanized a hloka hydrochloric le sulfuric acid. Metsi a litšila a kenyelletsa metsi a rinse ea acid le acid e litšila. Boholo ba metsi a litšila a indasteri ea tšepe a silafalitsoe ke maro a haeteroliki, a tsejoang hape ka hore ke oli e qhibilihang.
Setsi sa ho sebetsa ka tšepe
Litšila tse tsoang lits'ebetsong tsa ho qetela tsa tšepe hangata ke seretse (silt) se nang le litšepe tse qhibilihisitsoeng ka har'a maro. Ts'ebetso ea ho etsa tšepe ea tšepe, ho qeta tšepe le boto e hatisitsoeng ea potoloho (PCB) e hlahisa silt e ngata e nang le li-hydroxide tsa tšepe tse kang ferric hydroxide, magnesium hydroxide, nickel hydroxide, zinc hydroxide, copper hydroxide le aluminium hydroxide. Metsi a litšila a ho qeta ka tšepe a tlameha ho hloekisoa hore a ikamahanye le melaoana eohle e sebetsang ka lebaka la tšusumetso ea tikoloho le batho / liphoofolo tsa litšila tsena.
Liaparo tsa indasteri
Indasteri ea litšebeletso tsa masela ea khoebo e sebetsana le liaparo tse ngata selemo se seng le se seng, 'me liaparo tsena, lithaole, MATS ea fatše, joalo-joalo, li hlahisa metsi a litšila a tletseng oli, wadding, lehlabathe, grit, litšepe tse boima le metsoako ea lintho tse phelang e tlamehang ho phekoloa. pele ho phefumoloha.
Indasteri ea merafo
Mehatla ya morafo ke motswako wa metsi le majwe a matle a pshatlehileng a setseng ho tloswa ha diminerale tse tsepamisitsweng, tse kang kgauta kapa silifera, nakong ya tshebetso ya merafo. Ho lahleha ka katleho ha mesaletsa ea merafo ke phephetso e kholo bakeng sa lik'hamphani tsa merafo. Lithako ke molato oa tikoloho hammoho le phephetso e kholo ea litšenyehelo le monyetla oa ho fokotsa litšenyehelo tsa lipalangoang le tsa ho lahla. Merero e nepahetseng ea kalafo e ka felisoa matangoaneng a li-tailings.
Ho qhekella ha oli le khase
Metsi a litšila a tsoang ho cheka khase ea shale a nkoa e le litšila tse kotsi ebile a letsoai haholo. Ho feta moo, metsi a kopantsoeng le lik'hemik'hale tsa indasteri ka liente tsa Wells ho thusa ho cheka ho ne ho e-na le sodium e ngata, magnesium, tšepe, barium, strontium, manganese, methanol, chlorine, sulfate le lintho tse ling. Nakong ea ho cheka, lisebelisoa tsa radioactive tse hlahang ka tlhaho li khutlela holimo hammoho le metsi. Metsi a fracking a ka boela a ba le li-hydrocarbon, ho kenyelletsa le chefo e kang benzene, toluene, ethylbenzene le xylene e ka lokolloang nakong ea ho cheka.
Setsi sa ho hloekisa metsi / litšila
Sehlahisoa se seng sa lifeme tsa likhoerekhoere ke tlhahiso ea litšila tse nang le lintho tse ngata tse ka silafatsang. Esita le metsi a hloekisitsoeng ka chlorine a ka ba le lihlahisoa tse thibelang likokoana-hloko tse kang trihalomethane le haloacetic acid. Masalla a tiileng a tsoang litsing tsa ho hloekisa likhoerekhoere, tse bitsoang biosolids, li na le menontsha e tloaelehileng, empa hape li ka ba le litšepe tse boima le metsoako ea maiketsetso e fumanoang lihlahisoa tsa ntlo.
Ho lokisa lijo
Metsoako ea chefo e bolaeang likokoanyana, chefo e bolaeang likokoanyana, litšila tsa liphoofolo le manyolo lijong le metsing a litšila a temo kaofela a hloka ho laoloa. Ts'ebetsong ea ho lokisa lijo tse tsoang lihlahisoa tse tala, 'mele oa metsi o tletse moroalo o mongata oa likaroloana le lintho tse qhibilihang ka metsing kapa lik'hemik'hale. Litšila tsa tlhaho tse tsoang polaong le ts'ebetsong ea liphoofolo, maro a 'mele, mala le mali kaofela ke mehloli ea litšila tsa metsi tse hlokang ho phekoloa.
