Zolimba zoyimitsidwa, monga momwe dzinalo limatanthawuzira, ndi tinthu tating'onoting'ono toyandama m'madzi momasuka, nthawi zambiri pakati pa 0,1 microns ndi 100 microns mu kukula. Zimaphatikizapo koma sizimangokhala ndi silt, dongo, algae, tizilombo tating'onoting'ono, tinthu tating'onoting'ono ta organic, ndi zina zotero, kupanga chithunzi chovuta cha microcosm ya pansi pa madzi. Zolimba zoyimitsidwa m'madzi apansi ndi pansi nthawi zambiri zimachokera kuzinthu zachilengedwe, monga mchenga wotengedwa ndi mitsinje ndi plankton m'nyanja; pamene zolimba zoyimitsidwa m'madzi onyansa a m'tauni ndi m'madzi onyansa a m'mafakitale amasonyezanso momwe anthu amakhudzira ntchito za anthu, kuchokera ku fumbi pamalo omanga kupita ku ulusi ndi zidutswa zapulasitiki zomwe zimatulutsidwa ndi mafakitale, zomwe zimapanga zenizeni zowonongeka kwa madzi zamakono.
Njira zodziwira mwachangu zolimba zomwe zayimitsidwa makamaka zimaphatikizapo kugwiritsa ntchito mita yolimba yoyimitsidwa, njira yosefera ya membrane/sefa, njira yolekanitsa centrifugal, njira yoyezera (njira yowerengera) ndi njira yowunikira momwe zimakhalira. Njirazi zili ndi mawonekedwe awoawo ndipo ndizoyenera pazosowa ndi zikhalidwe zosiyanasiyana. pa
1. Chida choyezera zinthu choyimitsidwa: Iyi ndi njira yosavuta komanso yosavuta yoyezera. Mwa kutembenuza kutalika kwa mawonekedwe a chitsanzo kukhala deta, zotsatira zake zimawonetsedwa mwachindunji pazithunzi za LCD. Ndi oyenera mwamsanga kupeza muyeso muyeso wa inaimitsidwa nkhani ndende. pa
2. Njira yosefera ya membala wa sefa/sefa: Njira imeneyi imaphatikizapo kuika nembanemba ya fyuluta kapena pepala losefera mu botolo loyezera, kuyanika pa kutentha kwapadera ndi kuyeza kwake, ndiyeno kuthira madzi kuti ayezedwe mu botolo loyezera ndi fyuluta. nembanemba kapena sefa pepala, kusefa ndi kuyanika, ndiyeno kuyeza. Zomwe zili muzinthu zoyimitsidwa zimatsimikiziridwa ndi kufananiza kusiyana kwa kulemera kusanachitike ndi pambuyo pake. pa
3. Njira yolekanitsa ya Centrifugal: Nkhani yoyimitsidwa imasiyanitsidwa ndi mphamvu yapakati ndiyeno kuyeza. Njirayi ndi yosavuta kugwiritsa ntchito ndipo deta yoyezedwa ndiyolondola. Ndi imodzi mwa njira zodziwika bwino zomwe zaimitsidwa. pa
4. Njira yoyezera (njira yowerengera): Njirayi imafuna kugwiritsa ntchito kansalu ka sefa, yomwe ili yofanana ndi njira yosefera ya membrane, koma safuna kusefera. Sefa nembanemba yokhala ndi chitsanzo imawumitsidwa mwachindunji ndikuyesedwa. Ndi oyenera mwamsanga kudziwa zili inaimitsidwa nkhani. pa
5. Njira yowunika momwe kubalalidwira koyenera: Iyi ndi njira yowunikira kwambiri, yomwe ingaphatikizepo masitepe ovuta kwambiri ogwirira ntchito ndi zida, ndipo ndiyoyenera pazochitika zomwe zimafunikira kusanthula mwatsatanetsatane. pa
Posankha njira yoyenera, zinthu monga kukula kwa tinthu, zomwe zili, kugawa ndi morphology, komanso kulondola kwa mayeso ndi kuphweka kwa ntchito ziyenera kuganiziridwa. Posankha mwanzeru ndi kugwiritsa ntchito njirazi, zomwe zili muzamadzimadzi kapena mpweya zimatha kuyesedwa bwino ndikuyezedwa.
Ndikofunikira bwanji kuzindikira msanga zinthu zomwe zaimitsidwa m'madzi?
Nkhani yoyimitsidwa imakhudza kuwonekera komanso kukongola kwa matupi amadzi, komanso imatha kukhala chonyamulira cha zinthu zovulaza, kuwopseza zachilengedwe komanso thanzi la anthu.
Kufunika kozindikiritsa zinthu zoyimitsidwa m'madzi:
1. Kuunika kwa chilengedwe. Zinthu zoyimitsidwa m'madzi ndi chimodzi mwazizindikiro zofunika pakuwunika momwe madzi alili komanso thanzi lachilengedwe. Pogwiritsa ntchito chojambulira choyimitsidwa kuti chizindikire kuchuluka kwa zinthu zomwe zayimitsidwa m'madzi, kuwonekera, turbidity ndi kuchuluka kwa michere yamadzi m'madzi zitha kuyesedwa, komanso kuchuluka kwa kuipitsidwa kwamadzi ndi momwe kusintha kwachilengedwe kumakhudzira chilengedwe kumatha kumveka. .
2. Kukhudza kwachilengedwe Kuyimitsidwa m'madzi kumakhudza kwambiri thanzi ndi moyo wa zamoyo zam'madzi. Kuchuluka kwa zinthu zolimba zoyimitsidwa kungayambitse kuwala kosakwanira m'madzi, zomwe zimakhudza photosynthesis ya phytoplankton ndi momwe chilengedwe chimagwirira ntchito zamoyo za benthic. Kuphatikiza apo, zolimba zoyimitsidwa zimathanso kutsatsa ndikunyamula zinthu zapoizoni, zomwe zimawononga nsomba ndi zamoyo zina zam'madzi.
3. Thanzi laumunthu. Zolimba zina zoyimitsidwa, monga algae wapoizoni kapena zinthu zina zazing'ono zazing'ono, zitha kukhala pachiwopsezo ku thanzi la munthu. Poyang'anira zolimba zoyimitsidwa m'madzi, makamaka zomwe zingakhale ndi tizilombo toyambitsa matenda, zoopsa zomwe zingatheke paumoyo zikhoza kuchenjezedwa kuti zitsimikizire chitetezo cha madzi ndi thanzi la anthu. Choncho, m'pofunika kwambiri kuti sintha mofulumira inaimitsidwa zolimba chojambulira.
4. Ulimi ndi mafakitale. Zolimba zoyimitsidwa m'madzi zimathandizanso kwambiri ntchito zaulimi ndi mafakitale. Kuchulukitsitsa koyimitsidwa kolimba kumatha kusokoneza ubwino wa madzi amthirira, kuchepetsa ubwino wa nthaka ndi zokolola. Pakutulutsa mpweya m'mafakitale, kuyang'anira zolimba zomwe zayimitsidwa m'madzi zitha kuthandizira kuyang'anira ndikuwongolera kusokonezeka ndi kuipitsidwa kwamadzi akutayidwa.
Chifukwa chake, ndikofunikira kuwonetsetsa kuti zolimba zoyimitsidwa ndizolondola komanso zodalirika. Poyesa mita ya zolimba zoyimitsidwa zamadzi, kulondola ndi kusasinthasintha kwa zotsatira zoyezera zitha kuwongolera, kupereka maziko odalirika owongolera chilengedwe chamadzi komanso kuwunika kwamadzi. pa
Mwachidule, cholinga ndi kufunikira kozindikira zolimba zomwe zayimitsidwa sikumangotanthauza kumvetsetsa mtundu wa madzi, komanso kumateteza madzi, kusunga chilengedwe, kuonetsetsa kuti anthu ali ndi thanzi labwino, komanso kuyesa madzi abwino. Ndi gawo lofunikira kwambiri pakuwunika momwe madzi alili.
Ndi kupita patsogolo kwaukadaulo, mayankho osavuta komanso ogwira mtima abweretsedwa. The kunyamulika suspended zolimba mita LH-P3SS ndi chida chopangidwa ndi kupangidwa ndi Lianhua kuti azindikire zomwe zayimitsidwa zolimba m'madzi. Izi mita khalidwe madzi chimagwiritsidwa ntchito kutsimikiza kwa zolimba inaimitsidwa mu zimbudzi, kuteteza chilengedwe, zitsulo, madzi ozungulira, makampani mankhwala ndi mafakitale ena. Chidachi chimagwiritsa ntchito luso lapamwamba la spectrophotometric kuti lizisankha zokha kutalika kwa kutalika kwa mawonekedwe, kufewetsa kachitidwe ka ntchito, kuwongolera kulondola kwa kuzindikira, ndikuwongolera bwino ntchito.
Ndikoyenera kudziwa kuti kutsimikiza kwa zolimba zoyimitsidwa m'madzi kuli kutali ndi masewera owerengeka osavuta. Zimakhudzana ndi thanzi la chilengedwe komanso moyo waumunthu. Kuchuluka kwa zolimba zoyimitsidwa sikungochepetsa mphamvu yodziyeretsa yokha ya matupi amadzi, kuchepetsa kupereka kwa okosijeni wosungunuka m'madzi, ndikuyika chiwopsezo ku zachilengedwe zam'madzi, komanso kumawonjezera katundu pazimbudzi zamadzimadzi komanso kukhudza magwiridwe antchito ndi mtengo wa kuchiza zimbudzi. Choncho, kuyang'anitsitsa zolimba zoyimitsidwa sikungofunika kokha pachitetezo cha chilengedwe, komanso chitsimikizo chofunikira cha chitukuko chokhazikika.
