Nekuwedzera kwekunetseka kwezviwanikwa zvemvura pasi rose, tekinoroji yekurapa mvura yakasviba yave kutariswa zvakanyanya.Midziyo yekurapa mvura yakasviba yakabatanidzwa nePPH, senzira yekurapa mvura yakasviba inoshanda uye isingakuvadzi nharaunda, yave ichishandiswa zvakanyanya munyika nekune dzimwe nyika.
Kugadzirwa nekushanduka kwezvishandiso zvekuchenesa mvura yakasviba zvakabatanidzwa nePPH zvinogona kuteverwa kumashure kusvika kuma1970. Panguva iyoyo, nekukura nekukurumidza kwemaindasitiri nekukura kwemaguta, kurapwa kwetsvina kwakava dambudziko guru rezvakatipoteredza.kurapwa kwetsvinanzira dzinowanzo shandisa nzira dzemuviri nedzemakemikari, dzisinganyanyi kushanda zvakanaka uye dzinoshandisa simba rakawanda. Kuti vagadzirise dambudziko iri, vaongorori vakatanga kutsvaga nzira dzinoshanda zviri nani uye dzisingakuvadzi nharaunda.kurapwa kwemvura yakasvibamatekinoroji.
Mumamiriro ezvinhu aya, michina yekurapa mvura yakasviba yakabatanidzwa nePPH yakatanga kushandiswa. Inoshandisa nzira yekurapa yebhayoloji, ichisanganisa kurapwa kwemhepo, kurapwa kweanaerobic nedzimwe nzira dzekurapa, nekushanda zvakanaka, mari shoma yekushanda, nezvimwewo. Kubuda kwemidziyo yekurapa mvura yakasviba yakabatanidzwa nePPH kunokurudzira zvikuru kufambira mberi kwetekinoroji yekurapa mvura yakasviba, uye inova mhinduro inoshanda uye ine hushamwari kune zvakatipoteredza yekurapa mvura yakasviba.
Nekufambira mberi kuri kuramba kuripo muhunyanzvi hwetekinoroji uye zvinodiwa zvekuchengetedza nharaunda, michina yekurapa mvura yakasviba yakabatanidzwa nePPH iri kuramba ichikura uye ichichinja. Midziyo yekutanga yaive yekurapa tsvina kubva mudzimba, nharaunda diki nenzvimbo dzekutengeserana. Nekuwedzera kuri kuramba kuri kuita guta uye kukura nekukurumidza kwemaindasitiri, kudiwa kwekuchenesa tsvina kuri kuwedzera, uye kukura nekushanda kwemidziyo yekurapa tsvina yakabatanidzwa nePPH zvinogara zvichivandudzwa.
Maitiro ekurapa mvura yakasviba kuburikidza nePPH anobudirira zvikuru, izvo zvinogona kubvisa zvinhu zvipenyu, nitrogen, phosphorus nezvimwe zvinosvibisa mumvura yetsvina kuti zviwane zviratidzo zvakanaka zvemhando yemvura. Midziyo iyi ine chimiro chidiki uye nzvimbo diki, yakakodzera kushandiswa munzvimbo dzine nzvimbo shoma.michina yekurapa mvura yakasvibainowanzo shongedzerwa nehurongwa hwekudzora otomatiki, iyo inogonesa kutarisa nekugadzirisa kuri kure uye inoderedza mari yekushandisa nemaoko. Midziyo iyi inoshandisa tekinoroji yekufema inoshanda zvakanyanya kuderedza kushandiswa kwesimba; panguva imwe chete, dhizaini yayo yakanaka inobatsira kuderedza mari yekushandisa. Maitiro ekurapa kwebhayoloji ane hushamwari kune nharaunda uye anoderedza kukanganisa kwakaipa pamamiriro ekunze.
Kuti usarudze michina yakanaka yekuchenesa mvura yakasviba yakabatanidzwa nePPH, tekinoroji yekugadzira zvigadzirwa uye ruzivo rwekushanda kwepurojekiti zvakakosha, kazhinji, unofanirwa kusarudza zvigadzirwa zvinogona kuramba zvichikwanisa kumira zvakanaka pamusika, pano tinokurudzira michina yePPH inogadzirwa neLiding Environmental Protection Company, iyo inogona kugadziriswa zvichienderana nekudiwa kwemusika kwemhando yakakodzera yechigadzirwa.
