Icala Lokusebenza Lokunikezwa Kwamanzi Komphakathi eNanjing

Umsebenzisi: Inkampani ethile yokuhlinzeka ngamanzi e-Nanjing City

Ukuqaliswa kweziteshi zephampu eziphakela amanzi ezihlakaniphile kubhekane ngempumelelo nokukhathazeka kwezakhamuzi mayelana nokungcoliswa kwethangi lamanzi, umfutho wamanzi ongaqinile, kanye nokuhlinzekwa kwamanzi ngezikhathi ezithile. UNksz. Zhou, isakhamuzi esinokuhlangenwe nakho kokuzibonela, wathi, “Phambilini, umfutho wamanzi ekhaya wawungahambisani, futhi izinga lokushisa lamanzi aphuma ku-heater lamanzi lalishintshashintsha phakathi kokushisa nokubanda. Manje, lapho ngivula umpompi, umfutho wamanzi uzinzile, nezinga lamanzi lihle kakhulu. Ngempela sekulula kakhulu ukuwasebenzisa.”

Ukuthuthukiswa kwezinhlelo ezihlakaniphile zokuphakelwa kwamanzi esibili kumele intuthuko enkulu ekuqinisekiseni ukusatshalaliswa kwamanzi aphephile futhi anokwethenjelwa ezakhiweni eziphakeme zokuhlala. Kuze kube manje, leli qembu elihlinzeka ngamanzi selakhe iziteshi zokumpompa amanzi ezingaphezu kwe-100 ezindaweni zasemadolobheni nasezindaweni zasemakhaya, zonke esezisebenza ngokugcwele. Umphathi jikelele wale nkampani uphawule ukuthi njengoba inani lezakhiwo zokuhlala eziphakeme liqhubeka nokukhula emadolobheni nasemiphakathini, leli qembu lizoqhubeka nokugqugquzela ukumiswa kanye nokuthuthukiswa kwengqalasizinda yeziteshi zokupompa. Lokhu kuhlanganisa ukuthuthukisa i-精细化ukuphathwa kwezinhlelo zokuphakelwa kwamanzi esibili kanye nokuthuthukisa ngokuqhubekayo ubuchwepheshe bokulawula okukhaliphile ukuze kusebenze ukuhlinzekwa kwamanzi okuqhutshwa yidatha. Le mizamo ihlose ukubeka isisekelo esiqinile sokuthuthukiswa kwekusasa kwezinkampani zamanzi ezisezingeni elifanele nezihlakaniphile, ukuqinisekisa ukwethembeka “kwemayela lokugcina” lokulethwa kwamanzi kuso sonke isifunda.

Izakhiwo zokuhlala eziphakeme zisebenzisa amasistimu okuphakelwa kwamanzi okuguquguquka okungaguquguquki. Kule nqubo, amanzi aphuma epayipini elikhulu angena kuqala ethangini lokugcina lesiteshi sokumpompa ngaphambi kokuba acindezelwe amaphampu nezinye izinto zokusebenza bese ehanjiswa emizini. Nakuba lezi ziteshi zokumpompa umphakathi zisebenza ngaphandle kwabasebenzi abasesikhungweni, zigadwa ngesikhathi sangempela ngoxhumano lwenethiwekhi amahora angu-24 ngosuku. Amandla okulawula isilawuli kude avumela opharetha ukuthi balungise izilungiselelo zesistimu futhi baqaphe imingcele ebalulekile njengokucindezela kwamanzi, ikhwalithi yamanzi, namandla kagesi. Noma yikuphi ukufundwa okungavamile kubikwa ngokushesha ngokusebenzisa inkundla yokuphatha, okuvumela uphenyo olusheshayo kanye nokuxazululwa kwabasebenzi bezobuchwepheshe ukuze kuqinisekiswe ukuhlinzekwa kwamanzi okuqhubekayo nokuvikelekile.

Izinga lamanzi okuphuza lithinta ngqo impilo yomphakathi. Uma amanzi esibili ehluleka ukuhlangabezana nezindinganiso zokulawula—njengokuqukethwe kwensimbi esindayo ngokweqile noma insalela yesibulala-magciwane esinganele—kungase kuholele ezindabeni zezempilo ezifana nezifo zesisu noma ubuthi. Ukuhlola okuvamile kusiza ukuhlonzwa kusenesikhathi kwezingozi ezingaba khona, ngaleyo ndlela kuvinjwe imiphumela emibi yezempilo. NgokweZinga Lenhlanzeko Lamanzi Okuphuza laseShayina, ikhwalithi yokuphakelwa kwamanzi yesibili kufanele ihambisane naleyo yokuphakelwa kwamanzi kamasipala. Izidingo zokulawula zigunyaza ukuhlolwa kwekhwalithi yamanzi ngezikhathi ezithile okwenziwa amayunithi esibili anikezelayo ukuze kuqinisekiswe ukuthotshelwa komthetho, ukufeza isibopho esingokomthetho sokuvikela impilo yomphakathi. Ngaphezu kwalokho, idatha yekhwalithi yamanzi ingasetshenziswa ukuhlola isimo sokusebenza samathangi okugcina, izinhlelo zamapayipi, kanye nezinye izingqalasizinda. Isibonelo, ukwanda kokungcola emanzini kungase kubonise ukugqwala kwamapayipi, okudinga ukulungiswa ngesikhathi noma ukushintshwa. Le ndlela yokusheshisa inweba ukuphila kwemishini futhi iqinisekise ukusebenza okuzinzile nokuthembekile kohlelo lokuphakelwa kwamanzi.

Amapharamitha wokuqapha:
I-DCSG-2099 Multi-Parameter Water Quality Analyzer: pH, Conductivity, Turbidity, Residual Chlorine, Temperature.

Amapharamitha ekhwalithi yamanzi ahlukahlukene ahlinzeka ngemininingwane ngekhwalithi yamanzi ngemibono ehlukene. Uma zisetshenziswa ngokuhlanganyela, zinika amandla ukuqapha okuphelele kokungcoliswa okungaba khona ezinhlelweni zesibili zokuphakelwa kwamanzi kanye nesimo sokusebenza sempahla ehlobene. Ngephrojekthi yokulungiswa kwegumbi lepompo elihlakaniphile, i-Shanghai Boge Instrument Co., Ltd. inikeze i-DCSG-2099 multi-parameter multi-parameter yokuhlaziya izinga lamanzi ku-inthanethi. Lolu cingo luqinisekisa ukuphepha kwekhwalithi yamanzi ngokuqhubeka nokuqapha amapharamitha angukhiye afana ne-pH, conductivity, turbidity, residual chlorine, nezinga lokushisa.

Inani le-pH: Ibanga le-pH elamukelekayo lamanzi okuphuza liyi-6.5 ukuya ku-8.5. Ukuqapha amazinga e-pH kusiza ukuhlola i-acidity noma i-alkalinity yamanzi. Ukuchezuka ngale kwalolu banga kungase kusheshise ukugqwala kwamapayipi namathangi okugcina amanzi. Ngokwesibonelo, amanzi ane-asidi angagqwala amapayipi ensimbi, okungenzeka akhiphe izinsimbi ezisindayo njenge-ayoni nomthofu emanzini, okungase kweqe izinga lamanzi okuphuza aphephile. Ukwengeza, amazinga e-pH adlulele angashintsha imvelo ye-microbial yasemanzini, akhulise ngokungaqondile ingozi yokungcoliswa kwamagciwane.

I-Conductivity: I-Conductivity isebenza njengenkomba yengqikithi yokuhlangana kwama-ion ancibilikile emanzini, okuhlanganisa amaminerali nosawoti. Ukwenyuka okungazelelwe kwe-conductivity kungase kubonise ukugqashuka kwepayipi, okuvumela ukungcola kwangaphandle okufana nendle ukuthi kungene ohlelweni. Ingase futhi ibonise ukucwiliswa kwezinto eziyingozi emathangeni amanzi noma amapayipi, njengezithasiselo ezivela ezintweni zepulasitiki zekhwalithi ephansi. Lokhu okudidayo kungase kubonise ukungcoliswa kwekhwalithi yamanzi okungavamile.

I-Turbidity: I-turbidity ikala ukugcwala kwezinhlayiya ezimisiwe emanzini, okuhlanganisa isihlabathi, ama-colloid, nama-microbial aggregates. Amazinga aphakeme emfucumfucu ngokuvamile abonisa ukungcoliswa kwesibili, njengokungahlanzwa kwethangi okwanele, ukugqwala kwamapayipi nokuchithwa, noma ukuvaleka kahle okuvumela ukungcola kwamanye amazwe ukuthi kungene ohlelweni. Lezi zinhlayiya ezimisiwe zingase zithwale amagciwane, ngaleyo ndlela zandise izingozi zempilo.

I-chlorine eyinsalela: I-chlorine eyinsalela ibonisa ukugcwala kwezibulala-magciwane, ikakhulukazi i-chlorine, esele emanzini. Idlala indima ebalulekile ekuvimbeleni ukukhula kwamagciwane ngesikhathi sokuhlinzekwa kwamanzi okwesibili. I-chlorine eyinsalela enganele ingase iphazamise ukusebenza kahle kokubulala amagciwane, okungase kuholele ekwandeni kwamagciwane. Ngokuphambene, amazinga eqile angase abangele iphunga elibi, athinte ukunambitheka, futhi abe nomthelela ekwakhekeni kwemikhiqizo eyingozi yokubulala amagciwane. Ukuqapha i-chlorine eyinsalela kunika amandla ukulingana phakathi kokubulala amagciwane okusebenzayo nokwaneliseka komsebenzisi.

Izinga lokushisa: Izinga lokushisa lamanzi libonisa ukuhlukahluka kokushisa ngaphakathi kwesistimu. Amazinga okushisa aphakeme, njengalawo abangelwa ukukhanya kwelanga okuqondile emathangeni amanzi ehlobo, angasheshisa ukukhula kwamagciwane. Le ngozi iyanda lapho amazinga e-chlorine ayinsalela ephansi, okungase kuholele ekwandeni kwamagciwane ngokushesha. Ukwengeza, ukushintshashintsha kwezinga lokushisa kungase kube nomthelela ekuzinzeni komoyampilo oncibilikisiwe kanye ne-chlorine esele, okuthinta ngokungaqondile ikhwalithi yamanzi iyonke.

Kumakhasimende enza amaphrojekthi wesibili wokuphakelwa kwamanzi, siphinde sinikeze ngemikhiqizo elandelayo ezokhethwa:
