Iyini Ithangi Lokugcina Udaka Lwensimbi Engagqwali?
Ithangi lokugcina udaka lwensimbi engagqwali elingashintshiwe liyisitsha esikhethekile, esiqinile kakhulu sokugcina esakhelwe ukubamba, ukuhlanganisa, nokuphatha udaka lwamanzi angcolile kanye nemikhiqizo eyinsalela yezimboni ezindaweni zokuhlanza zomasipala nezimboni. Lakhiwe ngezingxube zensimbi engagqwali ezingagqwali (ezifana ne-Grade 304 noma i-316L), la mathangi akhelwe ukumelana nezimo ezinamakhemikhali anamandla, ezinamandla, neziguquguqukayo ezijwayelekile ezinqubweni zokuhlanza amanzi angcolile.
Njengoba izikhungo zokuhlanza amanzi angcolile zibhekene nemithetho eqinile yezemvelo kanye nezimfuno zokuphila isikhathi eside kwempahla, amathangi ensimbi engagqwali asephenduke izinga eliphakeme lokuphatha imfucuza eyinkimbinkimbi yoketshezi nokuqinile ngaphandle kokonakala okuvamile ezintweni ezijwayelekile.
Izimiso Eziyisisekelo Zobunjiniyela kanye Nokwakhiwa Okusebenzayo
Ukuphatha udaka olunemfucumfucu kudinga ukuzulazula endaweni enobuthi enezinga le-pH eliguquguqukayo, okuqukethwe okuqinile okuphezulu, namagesi abolayo. Amathangi ensimbi engagqwali anamuhla abhekana nalezi zinselele ngezindlela eziningana zobunjiniyela:
● Ungqimba Lwe-Chromium Oxide Oluzilapha: I- stainless steel yezinga eliphezulu yakha ngokushesha ungqimba oluncane, olungabonakali lapho ihlangana nomoya. Lo mgoqo uvimbela izinhlanganisela ezinamafutha, imithwalo enzima yezinto eziphilayo, kanye nomswakamo otholakala odakeni ekuhlaseleni ngqo uhlaka lwensimbi oluyisisekelo.
● Ukumelana ne-Hydrogen Sulfide (H2S) kanye ne-Bio-Corrosion: Ezinhlelweni zokugcina udaka, umsebenzi we-anaerobic uvame ukukhipha amagesi e-sulfide emoyeni wetangi. Ukukhethwa kwe-alloy efanele (njenge-316L) kuhambisana nokungenisa umoya okwanele endaweni engenhla kwetangi kuvimbela ukujiya kwe-sulfuric acid ekulimaleni kwensimbi.
● Ukuhambisana Komthwalo Ogudlukayo Nokuxuba: Ukugcinwa kwe-sludge kudinga ukuxuba okuqhubekayo noma okuphazamisekayo ukuze kugwenywe ukuhlala kwezinto eziqinile nokwakheka kwe-crust. Amathangi ensimbi engagqwali anamandla amakhulu okuqina nokuqina kwesakhiwo, amunca ngokuphepha i-torque egudlukayo namandla okudlidliza akhiqizwa izinto zokuxuba ezingaphansi kwamanzi ezinzima noma izinto ezixubayo eziphakathi.
● Izindawo Zangaphandle Ezinhlanzekile, Ezingangenwa Moya: Indawo ebushelelezi, engangenwa manzi ivimbela ukungcola kwezinto eziphilayo, ukunamathela kwe-biofilm, nokunqwabelana kwamafutha, iqinisekisa ukuhlanzeka kalula futhi ivimbele ukonakala kwesakhiwo.
I-Matrix Yokuqhathanisa: Izinto Zethangi Lokugcina i-Sludge
Ipharamitha Yokusebenza | Ithangi Lensimbi Engagqwali (316L) | Ithangi Lensimbi Lekhabhoni Elimboziwe | Isisekelo Sikakhonkolo Omunye | Ithangi Le-Fiberglass (FRP) |
Ukumelana Nokugqwala | Kuhle Kakhulu (Ukungazweli kwengxubevange yensimbi emakhemikhali anamandla odaka nokugqwala okunjengemigodi) | Kulingene (Kuba sengozini uma izintambo zangaphakathi ze-epoxy noma zengilazi ziba nezimbobo ezincane) | Kulingene (Kuba sengozini emakhemikhali ane-asidi ephilayo, ama-sulfate, nokuqhekeka kukakhonkolo) | Ukumelana namakhemikhali okuhle, kodwa kuba sengozini yokuba buthaka ngaphansi kwemithwalo enzima yomshini |
Ukugcinwa Nokuphila Isikhathi Eside | Okumangalisayo (Iminyaka engu-30 kuya kwengu-50+; ukugcinwa okuncane kwesakhiwo kuyadingeka) | Okulingene (Kudinga ukukhipha amanzi ngezikhathi ezithile, ukuhlolwa, nokufaka kabusha okungaphakathi) | Ukugcinwa Okuphezulu (Kudinga ukujova imifantu, ukuvala amajoyinti, nokuvuselela ukungangeni kwamanzi) | Okulingene (Kuthambekele ekuchithweni yi-ultraviolet ngaphandle nasekuqhekekeni okuncane) |
Ukushukunyiswa nengcindezi yemishini | Okuhle kakhulu (Amandla aphezulu okudonsa abamba ukudlidliza okunamandla komxube nemithwalo) | Kuhle ekuqaleni, kodwa imithungo yokushisela nezindawo zokunamathisela zingakhathele ngokuhamba kwesikhathi | Isisindo esiphezulu sesakhiwo, kodwa sithambekele ekuqhekekeni nasekuvuzeni kwamajoyinti | Amandla aphansi okumelana nokushaywa; kudinga ukufakwa ngokucophelela kwemixube esindayo |
Ukufakwa nokuhleleka ngamamojula | Okusheshayo (Ukwakhiwa okuhlelekile ngamabholithi noma okushiselwa endaweni kuvumela usayizi oguquguqukayo) | Okulingene (Kudinga ukushiselwa okuningi endaweni noma ukuhlanganiswa kwepuleti elisindayo) | Kuhamba kancane kakhulu (Kudinga amasonto okubumba, ukuthela ukhonkolo, nokupholisa) | Okulingene (Amayunithi enziwe ngaphambilini akhawulelwe ubukhulu bezokuthutha) |
Izicelo Eziyinhloko Ezikhungweni Zokuhlanza Amanzi Angcolile (WWTP)
1. Ukugcinwa Kwe-Sludge Eyinhloko Neyesibili: Ukugcina i-sludge ejiyile noma eluhlaza ye-biological ngaphambi kwezinqubo zokukhipha amanzi ezifana ne-belt filter presses noma ama-centrifuges.
2. Ukulawulwa Kokudla Kwe-Anaerobic Digestion: Ukusebenza njengamathangi okulinganisa noma okulungiselela ngaphambi kokwelashwa, alawula amazinga okulayisha okuphilayo ngaphambi kokuphakela ama-anaerobic digester.
3. Ukulinganisa Kwe-Industrial Effluent: Ukuqukatha i-chemical effluent enzima evela ezimbonini zendwangu, zemithi, zokucubungula ukudla, noma zamakhemikhali ngaphambi kokungathathi hlangothi.
4. Ukuhlelwa Kwe-Flocculated Sludge: Ukugcina i-sludge elashwe ngamakhemikhali exutshwe nama-polymers ngaphambi kokulahlwa kokugcina noma ukusetshenziswa emhlabathini.
Imibuzo Evame Ukubuzwa (FAQ)
Umbuzo: Iyini injongo eyinhloko yethangi lokugcina i-sludge lensimbi engagqwali?
Impendulo: Injongo yayo eyinhloko ukuqukatha ngokuphepha, ukulinganisa, nokulawula i-sludge yamanzi angcolile egxilile noma i-industrial effluent ngaphambi kokukhipha amanzi, ukwelashwa, noma ukulahlwa, ukuqinisekisa ukuthotshelwa kwemvelo nokuqhubeka komsebenzi.
Umbuzo: Kungani i-stainless steel ikhethwa kunensimbi yekhabhoni yokugcina i-sludge?
A: I-sludge iqukethe umswakama, amakhemikhali agqwalisayo, kanye nezinhlanganisela eziphilayo ezisebenzayo ezibola ngokushesha izembozo ezivikelayo zensimbi ekhabhoni. Insimbi engagqwali inikeza ukumelana nokugqwala okugcwele ubukhulu, okungokwemvelo ngesendlalelo sayo se-chromium oxide, okuqeda ingozi yokugqwala ngaphansi kwefilimu kanye nokufaka kabusha okubizayo ngaphakathi.
Q: Ukugqwala kuvinjelwa kanjani esikhaleni esingaphezulu kwethangi lapho i-hydrogen sulfide iqoqeka khona?
A: Ukunciphisa kuhilela ukukhetha izinga le-alloy eliphezulu njenge-Grade 316L (ene-molybdenum ukuze kuthuthukiswe ukumelana nokugqwala), ukugcina umoya ofanele esikhaleni esingaphezulu ukuze kuvinjelwe ukuqoqeka komswakama, kanye nokugwema izindawo ezinamandla okujiya lapho i-sulfuric acid ingakheka khona.
Q: Ingabe amathangi ensimbi engagqwali ane-sludge angamelana nama-agitator ezimboni anamandla?
A: Yebo. Insimbi engagqwali inamandla amakhulu okudonsa nokunwebeka kwesakhiwo, okuvumela izindonga zethangi namaringi okusekela ukuthi amunce ngokuphepha izingcindezi eziqhubekayo zomshini kanye nokudlidliza okunamandla okuvela kumshini wokuxuba udaka onamandla amakhulu.
