Ngokushuba okukhulayo kwemithombo yamanzi yomhlaba wonke, ubuchwepheshe bokuhlanza amanzi angcolile buye bathola ukunakwa okubanzi.Imishini yokuhlanza amanzi angcolile edidiyelwe ye-PPH, njengekhambi elisebenzayo nelinobungani nemvelo yokuhlanza amanzi angcolile, isetshenziswe kabanzi ekhaya naphesheya.
Ukuthuthukiswa nokuvela kwemishini yokuhlanza amanzi angcolile edidiyelwe ye-PPH kungalandelelwa emuva kuma-1970s. Ngaleso sikhathi, ngentuthuko esheshayo yezimboni kanye nokufudukela kwabantu emadolobheni, ukukhucululwa kwendle kwaba inkinga enkulu yemvelo. Izindlela zendabuko zokuhlanza indle ngokuvamile zisebenzisa izindlela ezingokomzimba nezamakhemikhali, ezinokwelashwa okuphansi kanye nokusetshenziswa kwamandla aphezulu. Ukuze kuxazululwe le nkinga, abacwaningi baqala ukuhlola ubuchwepheshe bokuhlanza amanzi angcolile obusebenza kahle futhi obunobungani nemvelo.
Kulo mongo, okokusebenza okudidiyelwe kokuhlanza amanzi angcolile kwe-PPH kwaba khona. Isebenzisa indlela yokwelapha yebhayoloji, ehlanganisa ukwelashwa kwe-aerobic, ukwelashwa kwe-anaerobic nezinye izindlela zokwelashwa, ngokusebenza kahle kokwelashwa, izindleko eziphansi zokusebenza, njll. Ukuvela kwemishini yokuhlanza amanzi angcolile ehlanganisiwe ye-PPH kukhuthaza kakhulu inqubekelaphambili yobuchwepheshe bokuhlanza amanzi angcolile, futhi iba yindlela ephumelelayo futhi ephumelelayo. isixazululo sokwelashwa kwamanzi angcolile esinobungani bemvelo.
Ngokuqhubeka okuqhubekayo kobuchwepheshe kanye nezidingo zokuvikela imvelo, okokusebenza okudidiyelwe kokuhlanza amanzi angcolile kwe-PPH nakho kuthuthuka futhi kuguquguquka njalo. Imishini yakuqala yayingowokuhlanza indle kalula nje emakhaya, emiphakathini emincane nasezindaweni zokuhweba. Ngokukhula okuqhubekayo kwesikali sedolobha kanye nokuthuthuka ngokushesha kwezimboni, isidingo sokuhlanza indle siyakhula, futhi izinga nokusebenza kwemishini yokuhlanza indle ehlanganisiwe ye-PPH nakho kuthuthukiswa njalo.
Inqubo yokwelapha yebhayoloji yemishini yokuhlanza amanzi angcolile edidiyelwe ye-PPH isebenza kahle kakhulu, engasusa ngempumelelo izinto eziphilayo, i-nitrogen, i-phosphorus nezinye izinto ezingcolisa indle ukuze kuzuzwe izinkomba ezinhle zekhwalithi yamanzi. Imishini inesakhiwo esihlangene kanye nezinyathelo ezincane, ezifanele ukusetshenziswa ezindaweni ezinendawo elinganiselwe.Imishini yokuhlanza amanzi angcolile ehlanganisiwe ye-PPH ngokuvamile ifakwe uhlelo lokulawula okuzenzakalelayo, oluvumela ukuqapha nokugcinwa okukude futhi kunciphise izindleko zokusebenza ngesandla. Izisetshenziswa zamukela ubuchwepheshe bokusebenzisa umoya obusebenza kahle kakhulu ukuze kuncishiswe ukusetshenziswa kwamandla; ngesikhathi esifanayo, ukwakheka kwayo okulungiselelwe kahle kusiza ukunciphisa izindleko zokusebenza. Inqubo yokwelapha yebhayoloji ihambisana nemvelo futhi inciphisa umthelela omubi ku-ecosystem.
Ukukhetha umshini omuhle wokuhlanza amanzi angcolile we-PPH, ubuchwepheshe bokuthuthukiswa komkhiqizo kanye nesipiliyoni sokusebenza kwephrojekthi kubalulekile, ngokujwayelekile, kufanele ukhethe imikhiqizo engaqhubeka nokuma ukuhlolwa kwemakethe, lapha ukuncoma imishini ye-PPH ekhiqizwe yi-Liding Environmental Protection Company, engenziwa ngokwezifiso ngokuya ngesidingo semakethe sohlobo olufanele lomkhiqizo.
