Monga njira yayikulu yoyendera kunyanja, zombo zimatenga gawo lalikulu pantchito yapadziko lonse. Komabe, ngati tizilombo tating'onoting'ono tomwe timadzitchere m'bwalolipanda chithandizocho, zidzaipitsa malo okhala zachilengedwe, kuwononga zachilengedwe kwambiri komanso ngakhale pachiwopsezo cha thanzi la munthu. " Kwa zaka makumi ambiri, mayiko ali ndi njira zatsopano zochizira madzi opangira mathira ambiri nthawi yomweyo.
Zam'madzi zoyipa zitha kugawidwa m'magulu atatu otsatirawa
1. Kukula kofewa monga masiponji, etc.;
2. Mabakiteriya ndi osakhazikika okhwima, monga mabakiteriya osiyanasiyana ndi algae;
3. Nyama zolimba zam'madzi, monga zingwe, ma biilve molluscs, etc.
Mitundu yoyipa kwambiri imakhala yovuta kwambiri
Idzawononga pamwamba pa mawonekedwe achitsulo ndikuyambitsa chilengedwe;
Zolengedwa zazikuluzikulu zimalepheretsa madzi ndi mapaipi okhetsa madzi, etc., zomwe zimakhudza kwambiri chitetezo ndi moyo wa maofesi a Marine.
Makina a akupanga mankhwala othandizira madzi, anti - zolengedwa zam'madzi makamaka zimagwiritsa ntchito "cavitation zotsatira za mafunde ena, ndikukula ndikumapuma munthawi yakumaso, kusintha kwa kusintha kwa thupi kumayambitsidwa.
Pamene thovu mu madzi amaphulika, amapanga mitundu yambiri yamikhalidwe yambiri madigiri am'madzi a Celsius, omwe amatha kuphwanya masentimita am'mimba, potero amatha kukwaniritsa cholinga chopewa zachilengedwe. Ukadaulo wa akupanga paukadaulo uli ndi zabwino zake. Sizophweka kokha mu kapangidwe ka chipangizo komanso kosavuta kugwira ntchito, komanso sizimatulutsa mawonekedwe achiwiri. Chofunikira kwambiri ndikuti mankhwala othandizira a akupanga ndi hydraulic cavitation ndiyabwino, ndipo kugwiritsa ntchito mphamvu sikokwanira.
Akupanga Anti - Maukadaulo a Nyanja Yamitundu yagwiritsidwa ntchito pochita ndikukwaniritsa zotsatira zabwino. Ukadaulo uli ndi zabwino zophweka, zachuma, kugwira ntchito, komanso kuteteza chilengedwe. Zingangochotsa chitsandikiriro cha zolengedwa zam'madzi pakhoma lamkati lamkati la mapaidzi am'madzi ndi zosefera, komanso kupha mphutsi zamadzi zam'madzi.
