Siyini Ithangi Le-Slurry? Incazelo Yezolimo Nezimboni
Ithangi likaslurry yisitsha sokugcina umquba oyiketshezi kanye nezinye izingxube ezinamandla aphezulu ezimpompa — ngokuvamile ama-2–10% okuqinile — agcinwa phakathi kokukhiqiza, ukwelashwa nokusetshenziswa emhlabathini noma ukusetshenziswa njengokudla kwe-anaerobic digestion. Izitolo zesimanje zikaslurry ngokuvamili zingamathangi ahlanganiswe ngengilazi ehlanganiswe nensimbi (GFS), insimbi emboziwe noma amathangi kakhonkolo afakwe izinhlelo zokushukumisa.
USlurry uyagqwala, uyagqutaza futhi usebenza ngokuphilayo: uhlasela insimbi, ususa izembozo ngamatshe, futhi wakha amagwebu agwinya umthamo wethangi. Imithetho iya ifuna ukugcinwa okumboziwe, okungavuzi — okwenza ukukhetha kwezinto nokwakhiwa kwamathangi kube nomthelela omkhulu kwezomnotho zepulazi nokuthobela imithetho.
1. Iyini Indima Yethangi Likaslurry Epulazini Nasezimbonini?
Isikhathi sokulondoloza phakathi kokukhiqiza nokusetshenziswa: Ubulongwe bezilwane bukhiqizwa nsuku zonke kodwa bungasetshenziswa kuphela ngezikhathi ezithile zokondla izitshalo. Imithetho (njengemithetho ye-EU ye-nitrate edinga ukugcinwa izinyanga ezi-4–6) yenza umthamo wethangi likabulongwe ube yimfuneko yokuthobela umthetho, hhayi into yokunethezeka.
Isitoreji sokudla kwe-anaerobic digestion: Ubulongwe buyisisekelo sokudla kwe-AD. Ithangi likabulongwe elixutshwe kahle londla ama-digester ngokuqukethwe okuqinile okungaguquki, kuzinzise ukukhiqizwa kwe-biogas — amathangi e-GFS asebenza kokubili ubulongwe obuluhlaza kanye nomsebenzi we-digestate endaweni eyodwa ehlanganisa izinto eziningi.
Umsebenzi wezimboni wobulongwe: Izinsalela zezimayini, imfucuza yokucubungula ukudla, udaka lwephepha kanye nodaka lokumba kudinga ukugcinwa kobulongwe okuxutshwayo, okumelana nokugqwala, ngezisekelo zobunjiniyela ezifanayo.
2. Ukwakha Ithangi Likabulongwe Eliphila Umsebenzi
Ukumelana nokugqwala kwamakhemikhali anamandla: I-slurry ikhiqiza i-H2S nama-asidi e-organic ngenkathi ithwala ama-chloride ne-ammonia. I-GFS enamel — ehlanganiswe nensimbi ngezinga lokushisa elingu-820–930°C — ayisebenzi kusukela ku-pH 1 kuya ku-14 futhi iqinisekiswa ngokuhlolwa kwe-holiday ye-DC engu-1500V ngokuvumelana ne-AWWA D103 ne-ISO 28765.
Indawo emelana nokwakheka kwamagwebu, engabambeli: Ubukhulu bendawo obungaphansi kuka-Ra 0.8 µm abunikezi izinto eziqinile namafutha amaphoyinti okubambelela. Kuhlangene nama-nozzle okuxuba akhelwe ngobunjiniyela, amathangi e-slurry e-GFS amelana nokwakheka kwamagwebu nokuguguleka okunciphisa umthamo emathangini anobukhulu obukhulu.
Isitoreji esimboziwe sokukhipha umoya nokubamba igesi: Imithetho eqinisiwe yokukhipha i-ammonia iphoqa amapulazi ukuthi asebenzise izindawo zokugcina udaka ezimboziwe. Amathangi e-GFS aboshiwe amukela izembozo ezingangeni moya, aguqule izindleko zokuthobela umthetho zibe igesi ebanjiwe noma ukunciphisa iphunga.

Imibuzo Ejwayelekile (FAQ)
UMBUZO 1: Liyini ithangi lodaka?
Ithangi lodaka ligcina umanyolo omanzi noma udaka lwezimboni olunokugxila okuphezulu kwezinto eziqinile phakathi kokukhiqiza nokusetshenziswa emhlabathini noma ukugaywa. Amathangi e-GFS odaka amelana nokugqwala kwe-pH 1–14 nokugqokeka iminyaka engaphezu kwengu-30, eqinisekiswe yi-AWWA D103 ne-ISO 28765.
UMBUZO 2: Ingakanani amandla okugcina udaka epulazini elidingayo?
Imithethonqubo eminingi idinga ukugcinwa izinyanga ezi-4–6 ezindaweni ezisengozini ye-nitrate. Amathangi e-GFS modular slurry akhula kusukela ku-20 m³ kuya ngaphezu kuka-60,000 m³ futhi angakwazi ukunwetshwa kamuva ngokubhuleka amaringi engeziwe.
Q3: Kungani amathangi e-slurry enza uqwembe ngokuhamba kwesikhathi?
Imicu, amafutha nezinto ezintantayo ezilula ziyantanta futhi zihlangane zibe uqwembe ezindongeni ezinamagagasi, ezingavuswanga kahle. I-GFS enobuso obushelelezi obungaphansi kuka-Ra 0.8 µm kanye nokuvuswa okuhleliwe kuvimbela uqwembe ukuba lungabambeki, kugcinwe umthamo wokugcina ogcwele.
Q4: Can a slurry tank be used for anaerobic digestion?
Yebo. I-slurry iyisithako esijwayelekile se-AD feedstock, futhi amathangi e-slurry e-GFS angacaciswa noma athuthukiswe kamuva ngama-mixer, ukushisisa nophahla olungangeni moya ukuze abe yimikhumbi yokugaya noma ondle i-biogas plant ngokuqondile.
