1. Inorganic impurities in water
greenhouses Masamba ntchito kukapanda kuleka ulimi wothirira, ambiri a madzi ndi bwino madzi. Iwo ankadziwa kuti zikamera wa mkulu-otaya mlingo chidzenje, ndi zitsime zina kugwiritsa ntchito nthawi pambuyo zinthu adzakhala mchenga wotitimira. Mchenga madzi ndi miyala zili ukuwonjezeka, mosakayikira kukapanda kuleka ulimi wothirira kukapanda kuleka mabowo chifukwa cha plugging. M'madera ena olemera chuma madzi pa nthaka, kukapanda kuleka ulimi wothirira makamaka ndi madzi mwa ngalande, umene ulinso zamitundu ambiri kuyambira zosafunika zochita kupanga. Awa kutsekereza ponena.
Solutions: Pakuti zosafunika zochita kupanga madzi, kuteteza plugging ayenera kulimbikitsa madzi fyuluta. Mu madzi pa unsembe zida zikuluzikulu kusefera, aliyense kutentha alimi ayenera kukhazikitsa machitidwe a dongosolo amphamvu monomer kusefera. Monga mchenga ndi miyala fyuluta, laminated, mauna fyuluta osakaniza, khalidwe madzi chingapezeke ntchito muyezo kukapanda kuleka ulimi wothirira. Ngati apeza kuti kutsekereza zinthu zinachitika mu dzenje pulagi mwa dzenje limodzi pa nthawi yomweyo, tiyenera kutsegula capillary kusintha madzi kuthamanga kuyeretsa zosafunika mu capillary ndi.

2. Organic impurities
Pakuti ena mwa feteleza ndi mankhwala kapena zinthu zina zakhudzana zitsime osaya kapena ngalande mtsinje, zosafunika organic madzi ndi chimodzi mwa zifukwa chifukwa cha kutchinga maso. Komanso, ngati ntchito ndondomeko kukapanda kuleka ulimi wothirira, fetereza si ntchito pambuyo akamaliza chokwanira Muzitsuka madzi, mosavuta chifukwa zosiyanasiyana algae mu payipi ndi ambiri kuswana, amene kutchinga maso a chimodzi mwa zifukwa .
Solutions: kusankha wabwino wa ulimi wothirira chitoliro kukapanda kuleka, kutenga wakuda filimu pansi pa ulamuliro wa ulimi wothirira pansi filimu. Pali njira ziwiri kuthetsa maso kutsekereza: Choyamba, ntchito asidi kuyeretsa disinfection chingapezeke, chopinga ndiponso Kupha algae ndi zotsatira tating'onoting'ono madzi. Amagwiritsidwa ntchito asidi perchloric, asidi nitric, asidi phosphoric, asidi sulfuric, ntchito kufunika pH kwa 5.5-6.0, mankhwala ayenera kukhala mosamalitsa ankalamulira ndende, kupewa zoipa mbewu. Acid kukonza amamvetsera kutsitsa kuthamanga dongosolo ulimi wothirira kusokoneza mlingo otaya ndi kusintha pickling tingati pakutha pa Muzitsuka ndi madzi. Lachiwiri ndi ntchito yapadera njira yolera yotseketsa algicide Muzitsuka.

3. Madzi ndi feteleza
Ntchito kukapanda kuleka ulimi wothirira fetereza pamene fetereza ngati solubility si zosafunika zokwanira kapena kuposerapo, adzachititsa kutchinga maso. Komabe, alimi masamba amafunika kulabadira vuto kuti ntchito m'madera ena masamba kupanga pansi, calcium, magnesium ndi zina zili zitsulo ion ndi mkulu, okhutira carbonate ndi mkulu, ife kawirikawiri kuti khalidwe madzi zimakhalanso zolimba, ntchito nthaŵi yaitali kukapanda kuleka ulimi wothirira chitoliro khoma kupanga sikelo kwambiri (kashiamu carbonate, etc.). Angagwiritsidwenso wothira feteleza ndi mankhwala pamene mpweya zidzachitika, chifukwa mu kutchinga maso.
Solutions: Pakuti m'madera khalidwe madzi molimba angagwiritsidwe ntchito ion kuwombola madzi purifier kwa madzi mankhwala. Pofuna kuteteza zosayembekezereka fetereza kutchinga maso za vutoli, alimi ayenera kugwiritsa ntchito wabwino, mkulu solubility, palibe yotsalira madzi sungunuka feteleza. Tsopano ndi kusintha kwa kupanga ndondomeko fetereza madzi sungunuka, ntchito njira zamakono ion kutsegula mu madzi zinthu sungunuka feteleza wolimba, akhoza ziletsa ayoni fetereza ndi madzi zitsulo kusonyeza mpweya.
