MPC ka metsi

Palo e kahodimodimo lumeletsoe mahloriso (MPC) ya likarolo tse kotsi ba mounted boemo liketso ntho e tloaelehileng bohloeki le melao ea tsamaiso. Ho hloleha ho boloka meeli tsena ke le molato oo boikarabelo ba violators ho latela molao. The karo-karolelano ea MPC ka metsi a fanang ka litaelo mabapi le tekanyong e makgabane bakeng kgotlelo, diteng tsa e leng ha e akarelletsa ho senya bophelo kapa bophelo ba motho.

Mehloli e ka sehloohong ea likarolo tse chefo li sebetsa e mengata ea liindasteri kgwebo rarahaneng. mesi e kotsi bona ka ho lekaneng ka matla silafatsa moea, mobu le metsi. likarolo tsa lik'hemik'hale, tse nang le tšusumetso e mpe ho hlokomela tikoloho ea rona, ka arotsoe ka lihlopha ho latela lengolo la bona la kotsi ho batho. Tsena li akarelletsa lintho tse le kotsi:

- tshohanyetso;

- phahameng;

- e leka-lekaneng.

Ho boetse ho na le sehlopha sa likarolo kotsi.

MPC ka metsi a tse fapa-fapaneng lintho tse lik'hemik'hale kenyelleditswe ka litafole khethehileng etselitsoeng. Hape, ho na le mekhoa e fapaneng, ho sebelisa e leng se etsang hore ho be bonolo ho a bale mamello moedi wa chefo. Di sebediswa bakeng sa litsebi tsa mehato taolo ya metsi bakeng sa ho sebelisoa tsa botho. Liketso tse joalo e ka sebedisa leha e le efe ho rōna. Ho lekane ho sekaseka boemo ba metsi a nooang ka lapeng la hao le bapisa le ditlwaelo ba lumeletsoe ho fumana ho eona likarolo tse sa tšoaneng. Mohlala, dikahare le ka milligrams ka litha e le nngwe ea lokela ho ba phahameng ho feta:

- omileng masalla - 1000;

- sulphate - 500;

- chloride - 350;

- koporo - 1;

- zinki - 5;

- tšepe - 0,3;

- mankanese - 0,1;

- barrel polyphosphate - 3,5.

Kakaretso ea thatafala ka metsing lokela ho sa feteng milligrams a supileng ka litha e le nngwe.

Ke ea bohlokoa haholo 'me taolo ya boemo ba mobu. naha eo ke leshala le filthara fapaneng metsoako. MPC metsi a likhoerekhoere, eo e lokolloa tswelela pele ka mobu, ba lokela ho boela ho iphaphatha le litekanyetso, e le ho falla kamehla ka lona e ka holimo dintho tse kotsi ka ho lekaneng ka matla contaminates tikoloho eohle.

Ho ea ka litloaelo le bohloeki, mobu ka 'na ba se na ho feta:

- 0,02 mg, / lik'hilograma benzopyrene;

- 3 mg, / lik'hilograma koporo;

- 130 mg, / lik'hilograma nitrate;

- 0,3 mg, / kg tsa toluene;

- 23 mg, / lik'hilograma zinki.

Ha o feta palo e kahodimodimo lumeletsoe mahloriso ka 'mele metsi a sebetsana le taolo ea tikoloho, o tla fumana hore na sesosa sa ketsahalo ena. hangata ha ho, ho eketseha ha palo ea mofuta wa lintho tse lik'hemik'hale susumetsa litšila kakaretso ea lelapa. Jwale, bothata ke kalafo ka ho khetheha a hlobaetsang le metsi ho tswa metsoako phosphate le naetrojene. E le hore ba rarolle bothata bona, u ka sebelisa mekhoa e meraro e fapaneng:

- k'hemistri;

- baeloji;

- pokello ea mekhoa e 'meli ea pele.

Tsebisa ya taolo makgabane moedi ka metsi sebelisa ho hloekisa lik'hemik'hale akarelletsa sebopeho metalfosfatov eo, ho insoluble, rarolla ho ea botlaaseng ba e setshelo khethehileng. Tšebetso ena e etsahala ka reagents. Ho sebelisa lik'hemik'hale tlhoekiso mokhoa ho pharaletseng sebelisoa ka dimela liindasteri. Ho phetha mesebetsi ena ka basebeletsi feela ho khethehileng koetlisitsoeng.

Ha u sebelisa phosphoric kapa P-libaktheria, mokhoa ona ka tlhoekiso tsa likokoana-hloko tsa metsi. Ke ea kajeno, tsela ea tlhaho ea ho atamela ho thibela ho palo e kahodimodimo lumeletsoe mahloriso. libakeng tse khethehileng tsa litanka kalafo ba fuoa fapanyetsana aerobiki libaktheria. mokhoa o joalo e sebelisoa ka biofilters e, litanka maswe le litanka aeration.

The pokello ea mekhoa tsa likokoana-hloko le tsa lik'hemik'hale sebelisoa ka tsamaiso ea kalafo metsi moo ho nang le tlhokahalo ho potlakisa le ho matlafatsa ho li bole kapele itsoara joang ka tsa litšila.
