Uhlelo lokwe -wa kwe-secureship oluhle kakhulu lwe-powtship kufanele lubhekwe ngokufanayo ngokusho kokwenziwa kwabantu bendawo, umhlaba, izimo zezomnotho kanye nezinye izinto, bese ukhetha imishini yokwelashwa kwendle efanelekile kanye ne-collocation efanelekile. I-Grille yisinyathelo sokuqala sohlelo lokwelashwa lwendle, olusetshenziselwa ukuvimba izinto ezinkulu eziqinile. I-grating ingahlukaniswa yaba yi-coarse yama-grille kanye nama-grille amahle, i-coarse grille isetshenziselwa ukunciphisa udaba olukhulu olumisiwe, njengamaqabunga, izikhwama zepulasitiki; Kusetshenziselwa ikakhulukazi ukunqamula udaba oluncane okumisiwe, njengokuchitha, imfucumfucu, njll. Ithangi lokuhlanza isihlabathi lisetshenziselwa ukususa izinhlayiya zesihlabathi nezinhlayiya eziningi ngengxenye enkulu yokuthuthwa kwendle. Ngokuvamile, isikali esithile sethangi sedimentation sisethwe ethangini ledimentation, kanye namandla adonsela phansi ukugeleza kwendle. Ithangi eliphambili le-sedimentation liyingxenye ebalulekile yohlelo lokuthuthwa kwendle, olusetshenziselwa ukususa udaba olumisiwe kanye nohlobo oluthile lwe-organic ekuthundleleni indle.
Ithangi eliyisisekelo sedimentation lixazulula le ndaba emiswe phansi ngenhla yemvelo noma i-oda lodaka, bese lidlula imishini yokukhishwa kwe-mud. Ithangi le-Biological Reaction liyingxenye ebalulekile yohlelo lokwelashwa lwendle, olusetshenziselwa ukungcolisa izinto eziphilayo futhi lususe ukungcola okufana ne-ammonia nitrogen ne-phosphorus. Ama-microorganisms ahlukahlukene ahlakulelwa echibini le-biological Reaction, kufaka phakathi ama-microbic microoorganisms kanye nama-anaerobic microorganisms, angaguqula izinto eziphilayo zibe yizinto ezilimazayo nge-metabolic action of microorganisms. Ithangi le-sedimentation yesibili liyithangi le-sedimentation ngemuva kwethangi le-biological arament, elisetshenziselwa ukuhlukanisa i-sludge eyenziwe ngethangi le-biological reaction lisuka ethangini eliphathwayo. Ithangi lesibili le-sedimentation liklebhula i-sludge evuliwe endaweni ephakathi nendawo yokuqoqa endaweni ye-sludge scraper noma umshini wokuvumela udaka, bese kuthi umshini wokuvumela udaka, bese kuthi-ke i-sludge esetshenzisiwe ibuyiselwa ethangini le-biological Reaccerux ngokusebenzisa imishini ye-sludge reflux. Imishini yokubulala amagciwane isetshenziselwa ukubulala amagciwane namagciwane namanye amagciwane ama-microorganisms ekukhuculweni kwendle. Izindlela zokubulala amagciwane ezijwayelekile zifaka ama-chlorination magciwane kanye nokubulala amagciwane e-ozone.
Ngaphezu kwalokhu okungenhla kwemishini yokwelashwa kwendle kwendle, kunemishini ethile ebalulekile, efana ne-blower, i-mixer, iphampu yamanzi nokunye. Lawa madivayisi adlala izindima ezahlukahlukene kwinqubo yokwelashwa kwendle, njengokuhlinzeka umoya-mpilo, ukuxuba indle, ukuphakamisa indle, njll.
Lapho ukhetha futhi kuhambisana nemishini yokwelashwa kwendle, kudingeka sicabangele izici zedolobha nesimo sangempela sedolobha. Isibonelo, ezindaweni ezinesibalo sabantu abaphansi kanye nendawo eyinkimbinkimbi, imishini yokwethaba kwendle encane nengomunyu ingakhethwa ngokuhamba okulula nokufakwa; Ezindaweni ezinezimo ezingcono zezomnotho, imishini enobuchwepheshe obuthuthukisiwe nokusebenza kahle kokwelashwa okuphezulu kungakhethwa. Ngasikhathi sinye, izindleko zokulungiswa kanye nokusebenza kwemishini, kanye nokukhululeka nokwethembeka kokuhlinzwa, kufanele kubhekwe.
