Munyika umo mvura yakachena iri kuva chitubu chinoshomeka, donhwe rega rega rine basa. Kusanaya kwemvura uye kusanaya zvakanaka kwemvura, izvo zvinowanzoguma nemafashamo, zvinowedzera kuoma kwekuchengeta mvura inonaya, ichiiparadza. Zvakakosha kuwana nzira dzekuchengetedza mvura kumba, zvose kuderedza kukanganisa kwezvakatipoteredza uye kuderedza mari yebhiri reimba.
Kusanaya kwemvura: Dambudziko remvura "yakagadzirwa".
Hazvina kudikanwa kugadzira alarm yekusimudza ruzivo nezve kuchengetedza mvura. Ichokwadi chokuti pasi redu rinoumbwa ne75% yemvura inowanzokanganwika, uye mishumo yekushomeka kwemvura yakachena inowedzerwa. Muzviitiko zvakawanda, dambudziko rekupa iri "yakagadzirwa" nekuda kwekushaikwa kwezvivakwa zvakakwana uye kusaita zvematongerwo enyika. Nekuronga nebasa, matanho anogona kutorwa kuona kuti mvura yave kuwanikwa nemunhu wese.
Mvura yakachena inochengeterwa munyika
Mvura yakachena inomiririra a 2.5% yemvura yose inowanika panyika, uye yakawanda yacho yakavharirwa mumazaya echando nomumvura iri pasi pevhu. Isingasviki 1% inowanikwa kune yakananga kudyiwa kwevanhu. Pazviwanikwa izvi zvishoma, zvekurima nezvipfuyo zvinoshandisa zvizhinji zvacho, zvichisiya kashoma kuti zvishandiswe nevanhu nemaindasitiri. Izvi zvinosimbisa kukosha kwekutonga zvirinani chiwanikwa ichi uye kudzivirira kutambisa kwayo.
Uyezve, kumativi 90% yenzvimbo dzinochengeterwa mvura yakachena pasi rose dziri muAntarctica, izvo zvinowedzera kukurumidza kwekuchengetedza zviwanikwa zvemunharaunda. Matunhu akawanda ari kutarisana nekushomeka kwechipo ichi, kunyanya chiri kukanganisa nyika dziri muAfrica nenzvimbo dzerenje dzeAustralia nekumaodzanyemba kweEurope.
Mamiriro ezvinhu muSpain
Kusanaya kwemvura muSpain hachisi chinhu chitsva, sezvinoratidzwa nenhoroondo dzekare. Munhau yose, peninsula yacho yakatambura nguva dzinoverengeka dzokusanaya kwemvura, dzakadai se 1944-1946, imwe yezvinonyanya kukuvadza, kana kuti ichangopfuura kubva ku2016-2017. Kusanaya kwemvura kwazvino chinongova chimwe chitsauko munyaya refu.
Kushaikwa kwezvivakwa zvekugadzirisa zvakanaka nzvimbo dzemvura muSpain kunowedzera mamiriro ezvinhu. Matunhu akadai seAndalusia neCatalonia ari kutotarisana nezvipingamupinyi zvekupa, zvichiratidza kusaronga kwakakwana kugadzirisa matambudziko aya anodzokororwa.
Hurumende dzingaita sei?
Hurumende dzinofanirwa kuita zvigadziriso zvenguva refu, sekuvandudza zvivakwa zvemvura, kuisa mari muzvirimwa zvekubvisa munyu uye kukurudzira matekinoroji ekuchengetedza mvura. Pamusoro pekusimudzira ruzivo pakati pevagari vemo, zvinodikanwa kuti maindasitiri makuru ashande zvakanyanya nekushandisa kwawo mvura, sezvo achidya zvisingaenzaniswi, sezvakaita maindasitiri emapepa uye semiconductor.
Panzvimbo pokungopomera vagari mhosva yekurasa mvura, hurumende dzinofanira kufunga nezvekuvaka zvirimwa zvemvura. desalination uye mukuvandudza nhepfenyuro dzekugovera. Kunyangwe desalination ichida simba, kushandiswa kwezvinhu zvinogonekazve kwaizoita kuti zvikwanise kuchengetedza mutengo wezvakatipoteredza wakaderera.
Chii chatingaita?
Maitiro ega ega anoitawo basa rakakosha mukuchengetedza mvura. Heano dzimwe nzira dzinoshanda uye dziri nyore dzekudzikisa kushandiswa kwemvura kumba:
1. Isai mapombi ekushandisa-pasi uye maaerator
Chinja matepi akajairika e mapombi ekushandisa mashoma kana kuisa maaerators kunogona kuderedza zvakanyanya kushandiswa kwemvura mumba. Midziyo iyi inodzikamisa kuyerera kwemvura pasina kukanganisa kudzvanywa, ichichengetedza huwandu hwemvura zuva nezuva.
2. Shandisa matangi anoshanda
Pane matangi ekudyiwa mashoma izvo zvinokutendera kuti ugadzirise huwandu hwemvura inoshandiswa nechero flush. Izvi zvinogona kureva kuchengetwa kuri pakati pe2 kusvika ku4 litres pakushandisa kwega kwega.
3. Tora mukana wemvura uye grey mvura
Kuunganidza mvura yekudiridza kunogona kubatsira kuderedza kushandiswa kwemvura yekunwa. Iwe unogona zvakare kushandisa zvakare grey mvura kubva kumashawa nemasinki emabasa akaita sekuchenesa imba kana kudiridza.
4. Mareducers ekugeza
Flow reducers mumashawa iva nechokwadi chokuti mvura yakawanda haina kurasika paunenge uchigeza. Uyezve, a kugeza nekukurumidza Maminitsi mashanu anogona kuchengetedza kusvika 50% mvura zvichienzaniswa neimba yekugezera.
Shanduko diki dzinoita mutsauko
Zvimwe zviito zviri nyore zuva nezuva zvinogona kuita mutsauko mukuru:
- Shandisa muchina wekugezesa nemudziyo wekusuka ndiro chete kana zvazara. Izvo zvakanyanya kushandisa mvura uye simba kumhanyisa midziyo iyi ine mitoro yakazara. Panyaya yedhishi yemazuva ano, inogona kushandisa kusvika ku40% pasi pemvura pane kugeza ndiro nemaoko.
- Defrost chikafu mufiriji kana pamhepo tembiricha, kudzivirira kuisiya pasi pemvura inoyerera.
- Shandisa mvura inotonhora kuchengeta chirongo mufiriji. Izvi zvinokudzivirira kuti usarege pombi ichimhanya kusvika mvura yabuda patembiricha yaunoda, kuchengetedza marita emvura zuva rega rega.
Kuderedza kushandiswa kwemvura ibasa ratinofanira kutora tose. Kubva pakuchinja kudiki mumaitiro edu ezuva nezuva kuenda kukudyara mumatekinoroji anoshanda kumba, chiito chese chakakosha kuchengetedza chinhu chakakosha ichi.
