Ngokunyuka koxinzelelo lwemithombo yamanzi ehlabathi, itekhnoloji yokucoca amanzi amdaka ifumene ingqalelo ebanzi.PPH izixhobo zokucocwa kwamanzi amdaka ezihlanganisiweyo, njengesisombululo esisebenzayo nesihambelana nokusingqongileyo, sisetyenziswe ngokubanzi ekhaya nakumazwe aphesheya.
Uphuhliso kunye nokuvela kwezixhobo zokucocwa kwamanzi amdaka ezihlanganisiweyo ze-PPH zinokulandelelwa emva phaya kwiminyaka yoo-1970. Ngelo xesha, ngenxa yophuhliso olukhawulezileyo lwemizi-mveliso kunye nokufudukela kwabantu ezidolophini, ukucocwa kogutyulo kwaba yingxaki enkulu yokusingqongileyo. Iindlela eziqhelekileyo zokucocwa kwamanzi amdaka ziqhele ukusebenzisa iindlela zomzimba kunye neekhemikhali, ezinonyango oluphantsi kunye nokusetyenziswa kwamandla aphezulu. Ukucombulula le ngxaki, abaphandi baqala ukuphonononga iindlela ezisebenzayo kunye nobuchwephesha bokucocwa kwamanzi amdaka obungqongileyo.
Kulo mxholo, izixhobo zokucocwa kwamanzi amdaka ezidityanisiweyo ze-PPH zabakho. Yamkela indlela yonyango lwebhayoloji, ukudibanisa unyango lwe-aerobic, unyango lwe-anaerobic kunye nezinye iindlela zonyango, kunye nokusebenza kakuhle kwonyango, iindleko eziphantsi zokusebenza, njl njl. Ukuvela kwe-PPH edibeneyo yokucoca izixhobo zokucoca amanzi amdaka kukhuthaza kakhulu inkqubela yobugcisa bokucocwa kwamanzi amdaka, kwaye iba yinto esebenzayo kwaye isisombululo sokucocwa kwamanzi amdaka ngokusingqongileyo.
Ngenkqubela phambili eqhubekayo yetekhnoloji kunye neemfuno zokhuseleko lokusingqongileyo, izixhobo zokucoca amanzi amdaka ezihlanganisiweyo ze-PPH nazo zihlala ziphuhla kwaye zivela. Izixhobo zakwangoko yayizezonyango olulula lwelindle olusuka kumakhaya, uluntu oluncinci nakwiindawo zorhwebo. Ngokwandiswa okuqhubekayo kwesikali sesixeko kunye nophuhliso olukhawulezayo lweshishini, imfuno yokucocwa kwelindle iyanda, kwaye isikali kunye nokusebenza kwezixhobo zokucoca ugutyulo oludibeneyo lwe-PPH nazo zihlala ziphuculwa.
Inkqubo yonyango yebhayoloji ye-PPH edibeneyo yokucoca izixhobo zamanzi amdaka isebenza kakuhle, enokususa ngokufanelekileyo izinto eziphilayo, i-nitrogen, i-phosphorus kunye nezinye izinto ezingcolileyo kwi-lindle ukufezekisa izikhombisi ezilungileyo zomgangatho wamanzi. Isixhobo sinesakhiwo esincinci kunye neenyawo ezincinci, ezilungele ukusetyenziswa kwiindawo ezinendawo encinci.Izixhobo zokucoca amanzi amdaka ezidibeneyo zePPH zihlala zixhotyiswe ngenkqubo yokulawula ngokuzenzekelayo, eyenza ukubeka iliso kunye nokugcinwa kude kunye nokunciphisa iindleko zokusebenza ngesandla. Isixhobo samkela itekhnoloji ye-aeration ephezulu yokunciphisa ukusetyenziswa kwamandla; kwangaxeshanye, uyilo lwayo olulungisiweyo lolwakhiwo lunceda ukunciphisa iindleko zokusebenza. Inkqubo yonyango yebhayoloji ihambelana nokusingqongileyo kwaye inciphisa impembelelo engalunganga kwi-ecosystem.
Ukukhetha i-PPH elungileyo edibeneyo yokucoca izixhobo zokucoca amanzi amdaka, iteknoloji yophuhliso lwemveliso kunye namava okusebenza kweprojekthi kubalulekile, ngokubanzi, kufuneka ukhethe iimveliso ezinokuqhubeka nokuma kuvavanyo lwemarike, apha ukucebisa izixhobo ze-PPH eziveliswe yi-Liding Environmental Protection Company, enokuthi yenziwe ngokwemfuno yemarike yohlobo olufanelekileyo lwemveliso.
