Kupanga zida zoyeretsera madzi otayira pamodzi ndi PPH komanso kusintha kwa mbiri

Chifukwa cha kukwera kwa mavuto a madzi padziko lonse lapansi, ukadaulo wokonza madzi otayidwa watchuka kwambiri.Zipangizo zoyeretsera madzi otayira zophatikizidwa ndi PPH, monga njira yothandiza komanso yosamalira chilengedwe pochiza madzi otayira, yakhala ikugwiritsidwa ntchito kwambiri m'dziko ndi kunja.
Kupanga ndi kusintha kwa zipangizo zoyeretsera madzi akumwa zogwiritsidwa ntchito ndi PPH kunayamba m'zaka za m'ma 1970. Panthawiyo, chifukwa cha kukula kwa mafakitale ndi mizinda, kukonza zimbudzi kunakhala vuto lalikulu la chilengedwe.kukonza zimbudziNjirazi nthawi zambiri zimagwiritsa ntchito njira zakuthupi ndi zamankhwala, zomwe sizimathandiza kwambiri pochiza komanso kugwiritsa ntchito mphamvu zambiri. Pofuna kuthetsa vutoli, ofufuza anayamba kufufuza njira zothandiza komanso zosawononga chilengedwe.kuchiza madzi otayiraukadaulo.
Pachifukwa ichi, zida zochizira madzi akuda zophatikizidwa ndi PPH zinayamba kugwiritsidwa ntchito. Zimagwiritsa ntchito njira yochizira yachilengedwe, kuphatikiza chithandizo cha aerobic, chithandizo cha anaerobic ndi njira zina zochizira, zomwe zimathandiza kwambiri pochizira, komanso zimakhala ndi ndalama zochepa zogwirira ntchito, ndi zina zotero. Kutuluka kwa zida zochizira madzi akuda zophatikizidwa ndi PPH kumathandizira kwambiri kupita patsogolo kwa ukadaulo wochizira madzi akuda, ndipo kumakhala njira yothandiza komanso yosamalira chilengedwe yochizira madzi akuda.
Ndi kupita patsogolo kosalekeza kwa ukadaulo ndi zofunikira pa kuteteza chilengedwe, zida zotsukira madzi zinyalala zophatikizidwa ndi PPH zikukula komanso zikusintha nthawi zonse. Zipangizo zoyambirira zinali zotsukira zinyalala kuchokera m'mabanja, m'madera ang'onoang'ono ndi m'malo amalonda. Chifukwa cha kukula kosalekeza kwa mzinda komanso kukula kwa mafakitale, kufunikira kwa kutsukira zinyalala kukuwonjezeka, ndipo kukula ndi magwiridwe antchito a zida zotsukira zinyalala zophatikizidwa ndi PPH zimakonzedwanso nthawi zonse.
Njira yochizira madzi otayira pogwiritsa ntchito PPH ndi yothandiza kwambiri, yomwe imatha kuchotsa zinthu zachilengedwe, nayitrogeni, phosphorous ndi zina zoipitsa m'madzi otayira kuti ikwaniritse zizindikiro zabwino za ubwino wa madzi. Zipangizozi zili ndi kapangidwe kakang'ono komanso malo ochepa, zomwe ndizoyenera kugwiritsidwa ntchito m'malo omwe ali ndi malo ochepa. PPH ikuphatikizidwazida zoyeretsera madzi otayiraNthawi zambiri imakhala ndi makina owongolera okha, omwe amathandiza kuyang'anira ndi kukonza patali komanso kuchepetsa ndalama zogwiritsira ntchito pamanja. Zipangizozi zimagwiritsa ntchito ukadaulo wothandiza kwambiri wopumira mpweya kuti zichepetse kugwiritsa ntchito mphamvu; nthawi yomweyo, kapangidwe kake kabwino kamathandiza kuchepetsa ndalama zogwirira ntchito. Njira yochizira matenda achilengedwe ndi yosamalira chilengedwe ndipo imachepetsa zotsatira zoyipa pa chilengedwe.

Kuti musankhe zida zabwino zoyeretsera madzi otayira zomwe zili ndi PPH, ukadaulo wopanga zinthu, komanso luso logwiritsa ntchito mapulojekiti ndikofunikira, nthawi zambiri, muyenera kusankha zinthu zomwe zingapitirizebe kupirira mayeso amsika, apa tikupangira zida za PPH zopangidwa ndi Liding Environmental Protection Company, zomwe zingasinthidwe malinga ndi kufunikira kwa msika kwa mtundu woyenera wa chinthu.
