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.
ISlurry iyingozi ngasikhathi sinye, iyagqwala, futhi iyasebenza ngempilo: ihlasela insimbi, ikhipha izinto zokugqoka ngesihlabathi, futhi yakha amagwebu agwinya umthamo wethangi. Imithetho iya ngokuya ifuna ukugcinwa okumboziwe, okungavuzi — okwenza ukukhethwa kwezinto kanye nobunjiniyela bethangi 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 zokudla 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 njengendawo yobulongwe obuluhlaza kanye ne-digestate esiteji esisodwa esihlanganisiwe.
Umsebenzi wezimboni wobulongwe: Izinsalela zezimayini, imfucuza yokucubungula ukudla, udaka lwephepha kanye ne-drilling muds nakho 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 aphilayo ngenkathi ithwala ama-chloride ne-ammonia. I-GFS enamel — ehlanganiswe nensimbi ku-820–930°C — ayisebenzi kusukela ku-pH 1 kuya ku-14 futhi iqinisekiswa ngokuhlolwa kweholide ye-DC engu-1500V kuya ku-AWWA D103 ne-ISO 28765.
Indawo emelana nokwakheka kwamagwebu, engabambeli: Ubushushu bendawo obungaphansi kuka-Ra 0.8 µm abunikezi izinto eziqinile namafutha amaphoyinti okubambelela. Kuhlangene nemishini yokuxuba eklanywe kahle, amathangi e-slurry e-GFS amelana nokwakheka kwamagwebu nokuguguleka okunciphisa umthamo emathangini anamagwebu amakhulu.
Isitoreji esimboziwe sokuthwebula ukukhishwa kwegesi: Imithetho eqinile yokukhishwa kwe-ammonia iphoqa amapulazi ukuthi asebenzise izindawo zokugcina udaka ezimboziwe. Amathangi e-GFS aboshelwe amukela izembozo ezingavumi igesi, okuguqula izindleko zokuthobela umthetho zibe igesi ebanjiwe noma ukunciphisa iphunga.

Imibuzo Ejwayelekile (FAQ)
UMBUZO 1: Liyini ithangi lodaka?
Ithangi lodaka ligcina umanyolo oyiketshezi noma udaka lwezimboni olunamaqinile aphezulu phakathi kokukhiqiza nokusetshenziswa emhlabathini noma ukugaywa. Amathangi e-GFS odaka amelana nokugqwala kwe-pH 1–14 nokugqokwa iminyaka engaphezu kwengu-30, aqinisekiswe yi-AWWA D103 ne-ISO 28765.
UMBUZO 2: Ingakanani indawo yokugcina udaka epulazini eliyidingayo?
Imithethonqubo eminingi idinga ukugcinwa izinyanga ezi-4–6 ezindaweni ezisengozini ye-nitrate. Amathangi e-GFS modular slurry akala kusukela ku-200 m³ kuya ngaphezu kuka-30,000 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 ezinamagwegwe, ezingaxutshwanga kahle. I-GFS engenasici ebushelelezi engaphansi kuka-Ra 0.8 µm kanye nokuxutshwa okuhleliwe kuvimbela uqwembe ukuba lungabambeleli, kugcine umthamo wokugcina ugcwele.
Q4: Can a slurry tank be used for anaerobic digestion?
Yebo. I-slurry ingumthombo ojwayelekile we-AD feedstock, futhi amathangi e-slurry e-GFS angacaciswa noma aguqulwe kamuva ngemishini yokuxuba, ukufudumeza, nophahla olungangeni moya ukuze abe yimikhumbi yokugaya noma ondle i-biogas plant ngokuqondile.
