Metsi a ka tlas'a lefatše a bitsoa a fumanehang botebong ba limithara tse 25 ho tloha holim'a lefatše. E thehiloe ka lebaka la matamo a fapaneng le pula ka mokhoa oa pula le lehloa. Li kenella fatše ebe li ipokellela moo. Metsi a ka tlas'a lefatše a fapana le metsi a ka tlas'a lefatše ka hore ha a na khatello. Ho feta moo, phapang ea tsona ke hore metsi a ka tlasa lefatše a nahanela liphetoho tsa sepakapaka. Botebo ba metsi a ka tlase ho lefatše ha bo fete limithara tse 25.

Boemo ba metsi a ka tlase

Metsi a ka tlasa lefatše a haufi haholo le lefatše, leha ho le joalo, boemo ba ona bo ka fapana ho latela sebaka le nako. E tla nyoloha ka mongobo o phahameng, haholo ha pula e na haholo le lehloa le qhibilihang. Le boemo bo susumetsoa ke linoka tse haufi, matša le mefuta e meng ea metsi. Nakong ea komello, tafole ea metsi ea fokotseha. Ka nako ena, o nkuoa a le tlase ka ho fetesisa.

Boemo ba metsi a ka tlase ho lefatše bo arotsoe ka mefuta e 'meli:

  • tlase ha boemo bo sa fihle 2 metres. Meaho e ka hahuoa sebakeng se joalo;
  • boemo bo phahameng ho feta limithara tse 2.

Haeba u etsa lipalo tse fosahetseng tsa botebo ba metsi a ka tlase ho lefatše, sena se sokela: likhohola tsa moaho, ts'enyeho ea motheo le mathata a mang.

Ketsahalo ea metsi a ka tlasa lefatše

Ho tseba hantle hore na metsi a ka tlas'a lefatše a hokae, o ka qala ka ho etsa litlhahiso tse bonolo. Ha botebo bo sa teba, matšoao a latelang a tla bonahala:

  • leru la li-midges "le holimo" ka holim'a lefatše mantsiboea;
  • sebaka seo limela tse ratang mongobo li holang hantle.

Hape o ka sebelisa mokhoa o mong oa setso. Kenya mofuta o mong oa lisebelisoa tsa desiccant (mohlala, letsoai kapa tsoekere) ka pitseng ea letsopa. Ebe o e bekha ka hloko. E phuthele ka lesela ebe o e pata fatše ka botebo ba lisenthimithara tse 50. Kamora letsatsi - bula, 'me u be le boima hape. Ho latela phapang ea boima, ho tla khonahala ho tseba hore na metsi a haufi hakae le lefatše.

U ka tseba ka boteng ba metsi a ka tlase ho 'mapa oa hydrogeological sebakeng seo. Empa tsela e sebetsang ka ho fetisisa ke ho cheka ho hlahloba. Mokhoa o sebelisoang haholo oa kholomo.

Litlhaloso

Ha metsi a ka tlung a itlela ka tlhaho, joale a ka nooa. Tšilafalo ea mokelikeli e susumetsoa ke metsana le litoropo tse haufinyane, hammoho le haufi le metsi holim'a lefatše.

Metsi a ka tlase ho lefatše a arotsoe ka mefuta e fapaneng molemong oa matsoai a ona, ka hona ke a latelang:

  • insipid;

  • carbonate;
  • e seng carbonate.

Ntle le moo, ho na le metsi a ka tlase ho lefatše, a nang le lintho tse ngata tse kotsi. Metsi a joalo hangata a fumanoa haufi le litšila tsa mobu, tse nang le lithotobolo tsa litšila tsa lik'hemik'hale kapa tsa mahlaseli a kotsi.

Likotsi tsa metsi a ka tlase ho lefatše

Metsi a ka tlas'a lefatše le ona a na le mathata a teng, ka mohlala:

  • likokoana-hloko tse fapaneng (le likokoana-hloko hape) ha ho etsoa metsi;
  • thatafala. Sena se ama ho fokotseha ha leseli la lipeipi tseo metsi a fepeloang ka tsona, kaha lipeeletso tse khethehileng li behiloe ho tsona;
  • turbidity, ka lebaka la hore ho na le likaroloana tse itseng ka metsing;
  • litšila metsing a ka tlas'a lefatše a lintho tse fapaneng, likokoana-hloko, letsoai le likhase. Kaofela ha bona ba khona ho fetola eseng feela 'mala, empa hape le tatso ea metsi, monko oa eona;
  • liperesente tse kholo tsa liminerale. E fetola tatso ea metsi, ka hona ho hlaha tatso ea tšepe;
  • kenella ka metsing a ka tlasa lefatše a nitrate, ammonia. Li kotsi haholo bophelong ba motho.

Hore metsi a fetohe boleng bo holimo haholo, a tlameha ho sebetsoa ka hloko. Sena se tla thusa ho tlosa litšila tse fapaneng.
