Mafirita chinhu chakakosha chegreenhouse kudiridza masisitimu. Basa guru remasefa nderekuparadzanisa zvidimbu zvakaturikwa kana kunyungudika kubva mumvura. Mukudiridzira, mafirita anotarisira kubvisa zvidimbu zvinokanganisa hutano hwezvirimwa kana kugona uye kufanana kwekugovera mvura.
Nepo madiridziro ese anofanirwa kuve nematanho akawanda uye marudzi emasefa, zvakakosha kuti usarudze sefa chaiyo. Varimi vanofanira kusarudza mafirita zvichienderana nedambudziko ravakanangidzirwa, kuenderana nemadiridziro akamiswa, uye mari yekusefa.
Target matambudziko uye kusefa sarudzo
Heano tarisa kune zvakajairika mvura inosvibisa inowanikwa mumagreenhouses uye mafirita anokurudzirwa kubvisa izvo zvinosvibisa.
Organic particles zvinosanganisira marara, algae, uye zvirwere. Utachiona huzhinji hudiki zvakanyanya (semuenzaniso, mavhairasi particles anogona kuita asingasviki 1 μm uye mamwe fungal zvimiro zvishoma pasi pe200 μm) uye kuabata nesefa kunoda saizi diki yakanyanyisa, senge Ultra-fine membrane filtration. Nekudaro, kusefa kwemembrane hakuwanzo shandiswa pachishandiso ichi nekuti mari yekudyara uye yakanyanya hunyanzvi basa inodiwa inodhura.
Vatsvagiri vepaUniversity yeCalifornia neMichigan State University vakaedza masefa ejecha anononoka uye anokurumidza kubviswa Phytophthora sp. uye Pythium sp. uye akaona migumisiro yakanaka. Masefa aya anobvisa utachiona, pamwe nekusanganiswa kwemaitiro emuviri uye ebhayoloji. Masefa ejecha anononoka anoumba biofilm layer (inozivikanwa se schmutzdecke) inoderedza kana kuvharira utachiona kuburikidza nezvipingaidzo zvemuviri uye nzira dzekudzora zvipenyu. Nekudaro, mafirita enhau anogona kuvhara kana marara akakurisa (semuenzaniso, masora). Naizvozvo, coarse pre-filter inokurudzirwa. Screen uye midhiya mafirita anoshanda mukubvisa hombe organic tsvina nesora; dzinouya muhukuru hwakasiyana-siyana uye hadzidhuri.
Inorganic particles kana marara anosanganisira yakanaka granular minerals sejecha, ivhu, uye silt. Izvi zvinosvibisa zvinogona kubviswa nebepa, sock, skrini, kana disc mafirita. Sock mafirita anobvisa akamiswa zvisingaite zvimedu zvakanaka. Zvisinei, vane nzvimbo duku uye saka vanovhara nyore nyore. Sock filters inokurudzirwa sedanho rekupedzisira rekusefa. Usashandise membrane filtration kubvisa yakamiswa inorganic particles kana organic tsvina. Izvi zvinosvibisa zvinogona kukuvadza muviri membranes.
Inorganics yakanyungudika inosanganisira chero munyu wakanyungudutswa unowanzo kunyorwa pakuongorora kwako mvura (semuenzaniso: iron, carbonates, calcium, sodium, etc.). Membrane filtration inokurudzirwa kubvisa munyu wakanyungudika kubva mumvura. Reverse osmosis ichabvisa maion ese kunze kweboron kubva mumvura. Iron uye manganese zvinogona zvakare kubviswa kuburikidza nemusanganiswa weoxidation (chlorine kana permanganate), ichiteverwa nekusefa nemasefa akachajwa (semuenzaniso, greensand).
Yakanyungudika organics inosanganisira agrochemicals uye humic acids. Granular activated carbon filtration inobvisa huwandu hukuru hweagrochemicals kubva mumvura. Vatsvakurudzi veYunivhesiti yeFlorida vakaona kuti granular activated carbon yakashanda pakubvisa makemikari akawanda, kusanganisira insecticides (acephate, bifenthrin, chlorpyrifos, uye imidacloprid), herbicides (glyphosate uye triclopyr), zvinomera kukura kwemiti (flurprimidol, paclobutrazole), uye uniconazole. uye sanitizer yemvura (quaternary ammonium chloride, sodium hypochlorite, uye peroxygen). Granular activated kabhoni mafirita anokurudzirwa kana uchishandisa chero sosi yemvura kana yekudiridza ine zvisaririra zvekurima - madziva ekubata, mvura yakadzokororwa, kana masisitimu ekudiridza.
Zvakakosha kufunga nezve kusefa mune greenhouse irrigation systems
Isa akawanda nhanho yekusefa - kubva payakaomarara kusvika kune yakanaka - kudzivirira kuvhara sisitimu uye kuwedzera kushanda kwekubvisa zvimedu. Uyewo, funga nezvemutengo. Semuyenzaniso, simbi sikirini mafirita ane mutengo wakaderera uye anogona kushandiswa kubvisa akakasharara zvimedu. Fiber mafirita (bepa kana sock) akati dhure kudarika mafirita, uye anowanzo shandiswa sedanho rekupedzisira rekusefa. Gara sefa mvura yako zvakanaka usati washandisa membrane sefa; kusaita izvi kunokuvadza membrane dzinodhura.
Chengetedza masefa. Geza masefa nguva nenguva kudzivirira kuvhara kana kubvarura masefa. Sarudza mafirita ane otomatiki backwash paunenge uchisefa organic uye inorganic tsvina.
