Ndi chitukuko cha mizinda, zida zotsukira zinyalala zakhala gawo lofunika kwambiri pa ntchito yomanga mizinda. Komabe, kukonza zinyalala m'madera akumidzi sikunalandire chisamaliro chokwanira. M'zaka zaposachedwapa, chifukwa cha kupita patsogolo kwa chidziwitso choteteza chilengedwe, matauni akumidzi nawonso akhoza kukhala ndi madzi oyera a mitsinje. Tiyeni tiwone momwe zida zotsukira zinyalala zimagwiritsidwa ntchito.
M'matauni akumidzi, malo oyeretsera zinyalala nthawi zambiri amakhala ang'onoang'ono, koma zida zoyeretsera zinyalala za mbr zimatha kuchita bwino ntchito yoyeretsera zinyalala pamalo ochepa, zomwe zimathandiza kuthetsa vuto la kuyeretsa zinyalala. Sikuti zokhazo, chifukwa cha kunyamula kwake kwakukulu. Zipangizo zoyeretsera zinyalala za MBR zakhala njira yofunika kwambiri yoyeretsera zinyalala zakumidzi.
Zipangizo zotsukira zinyalala za MBR ndi bioreactor yochokera ku ukadaulo wa nembanemba, womwe umagwiritsidwa ntchito makamaka pochiza zinyalala zapakhomo, madzi otayirira a m'mafakitale ndi madzi otayirira azachipatala. Chinthu chachikulu chomwe chimagwiritsidwa ntchito ndi chipangizochi ndikugwiritsa ntchito ukadaulo wodziyeretsa wokha, womwe uli ndi ubwino wogwiritsa ntchito bwino kwambiri, kusunga mphamvu, kuteteza chilengedwe, komanso kugwiritsa ntchito mosavuta.
Zipangizo zotsukira zinyalala za mbr zimatha kuthetsa
1. Kuyeretsa zimbudzi za m'mudzi
Vuto la kuyeretsa zinyalala m'madera akumidzi lakhala vuto nthawi zonse, ndipo njira zachikhalidwe zotsukira zinyalala nthawi zambiri sizingakwaniritse zosowazo. Zipangizo zotsukira zinyalala za mbr zimatha kuthetsa vutoli bwino. Zinyalala zomwe zili m'mudzimo zikakonzedwa, zimatha kusinthidwa kukhala madzi oyera, omwe angagwiritsidwe ntchito pothirira minda, kuswana ndi madzi apakhomo.
2. Kuyeretsa zinyalala m'madera akumidzi oyendera alendo
M'zaka zaposachedwapa, zokopa alendo akumidzi zakhala njira yotchuka yoyendera alendo. Komabe, vuto la kuyeretsa zinyalala m'madera akumidzi oyendera alendo silinathetsedwe. Zipangizo zotsukira zinyalala za mbr zimatha kuthetsa vutoli bwino, zomwe zimathandiza alendo kuyenda m'malo oyera komanso aukhondo.
3. Kukonza zimbudzi zamafakitale akumidzi
Chifukwa cha kufulumira kwa mafakitale m'madera akumidzi, kutulutsa madzi otayira m'mafakitale kukuwonjezeka chaka ndi chaka. Zipangizo zotsukira zinyalala za mbr zimatha kuchiza bwino madzi otayira m'mafakitalewa ndikuchepetsa kuipitsa chilengedwe.
Ubwino wa zida zotsukira madzi a mbr ndikuti zida zotsukira madzi a mBR zimagwiritsa ntchito ukadaulo wapamwamba wa nembanemba, womwe ungachotse bwino zinthu zachilengedwe, nayitrogeni, phosphorous ndi zoipitsa zina m'madzi a m'nyanja, kuti ubwino wa madzi ukhale wabwino. Mtundu wophatikizana wa zida zotsukira madzi a mBR ndi wosinthasintha kwambiri, ndipo ukhoza kuphatikizidwa mosinthasintha malinga ndi makhalidwe osiyanasiyana a madzi ndi zofunikira pakuchiza kuti ukwaniritse zotsatira zabwino kwambiri pakuchiza. Zipangizozi zimagwiritsa ntchito njira yowongolera yokha komanso zigawo zodalirika za nembanemba, kuti zigwire ntchito mokhazikika komanso modalirika, ndikusunga magwiridwe antchito abwino kwa nthawi yayitali. Pogwiritsa ntchito ukadaulo wapamwamba wobwezeretsa mphamvu, zimatha kuchepetsa kugwiritsa ntchito mphamvu moyenera, ndipo nthawi yomweyo, zimathanso kubwezeretsanso madzi okonzedwa kuti zikwaniritse cholinga chosunga mphamvu komanso kuteteza chilengedwe.
Choyambitsa matenda a MBR membrane chomwe chinapangidwa ndi Liding Environmental Protection chili ndi mphamvu yokonza matani 100-300 patsiku, zomwe zimatha kusakanikirana kufika matani 10,000. Bokosi la bokosilo limapangidwa ndi chitsulo cha kaboni cha Q235, chomwe chimayeretsedwa ndi UV, chomwe chimalowa bwino kwambiri ndipo chimatha kupha mabakiteriya 99.9%. Gulu la membrane lapakati lili ndi ma membrane a ulusi wolimba. Takulandirani kuti mukafunse ngati muli ndi zosowa zilizonse.
