Amathangi okwelapha i-Leachate: Imikhumbi yokucubungula i-leachate yokulahla imfucumfucu ne-biogas
I-leachate yokulahla imfucumfucu ingenye yamanzi angcolile okunzima kakhulu ukuwelashwa: i-COD ifinyelela kumashumi ezinkulungwane zama-mg/L, i-ammonia, izinsimbi ezisindayo namakhemikhali ashintsha njengoba indawo yokulahla imfucumfucu iguga. Amathangi aphethe ukwelashwa kwayo kufanele abe nolaka njengoketshezi ngokwalo.
Ithangi lokwelapha i-leachate ngumkhumbi wokucubungula — i-reactor ye-UASB/EGSB, ibhesini le-aerobic, noma isitoreji se-buffer — elakhiwe ngenjongo ye-leachate enamandla kakhulu yokulahla imfucumfucu noma ye-biogas. Ukwakhiwa kwe-Bolted GFS nge-pH 1–14 fused enamel, ngokwe-AWWA D103 ne-ISO 28765, kunikeza iminyaka engaphezu kwengu-30 kulo msebenzi ogqwala.
Yini Okudingwa Ukwelashwa Kwe-Leachate Emathangini Ayo?
Ukubekezeleka kwe-COD ephezulu: i-leachate COD ngokuvamile isebenza ngo-5,000–60,000 mg/L; ama-reactor e-anaerobic (UASB/EGSB) aphatha umthwalo omkhulu.
Ukushintshashintsha kwamakhemikhali: i-pH isukela ku-acidic young leachate kuya ku-alkaline old leachate — ukumelana nokugqwala kwe-full-range kuyimpoqo.
Ukuphathwa kwegesi: amathangi e-anaerobic athwebula i-biogas (60–70% CH4) ngophahla olungangeni moya nezinhlelo zokuphepha.
Ukuguquguquka kwenqubo: ukuhlelwa kwe-AO/A2O, i-MBR kanye nokucwengwa kwe-polishing kwengeza amathangi e-aerobic nama-clarifier.
Amathangi Okwelashwa Kwe-Leachate Akhiwa Kanjani?
Ukuklanywa kwe-reactor: amathangi e-UASB/EGSB anama-settler angaphakathi, ukuqoqwa kwegesi kanye namagobolondo e-GFS angagqwali.
Amabhesini okungenisa umoya: amathangi avulekile noma amboziwe anama-diffuser okwenza i-nitrification nokucwengwa kwe-BOD.
Ibhafa nokugcinwa: amathangi okulinganisa nokubamba agudluza ukungena kahle ekwelashweni.
Amazinga: AWWA D103 isakhiwo, ISO 28765 enamel, kanye namakhodi endawo ezemvelo nokuphepha kwegesi.
Kungani i-GFS iyona ezenzakalelayo kusetshenziswa kwe-leachate
Amakhemikhali aphelele: i-pH 1–14 enamel ehlanganisiwe imboza i-leachate encane ene-asidi nendala ene-alkaline ngaphandle kokushintsha i-liner.
Ukuvikelwa kwendawo yegesi: i-H2S condensate iyathambiswa ungqimba olufanayo olungasebenzi oluvikela indawo yoketshezi.
Ikhwalithi eqinisekisiwe: Ukuhlolwa kweholide kwe-1500V DC kwephaneli ngayinye kubhala umgoqo ongenazimbobo.
Isilinganiso: amathangi e-leachate asukela kumabhafa amancane kuya kufakelo lwe-10,392 m³+, anweba ngezigaba.

Amathangi okwelapha i-leachate kufanele afane nokucasuka koketshezi — i-bolted GFS enamel iletha ukumelana namakhemikhali e-pH 1–14, ukuvikelwa kwe-H2S kanye nokuqinisekiswa kwe-1500V okubhaliwe okudingwa yinsiza ye-leachate ene-COD ephezulu iminyaka engaphezu kuka-30.
Imibuzo Ejwayelekile (FAQ)
Q1: Liyini ithangi lokwelapha i-leachate?
Umkhumbi wokucubungula we-leachate yokulahla udoti noma i-biogas enamandla — ama-reactor e-UASB/EGSB, amabhesini e-aerobic noma izindawo zokugcina — akhelwe ngokwe-AWWA D103 nge-GFS enamel ye-pH 1–14 ukuze isebenze iminyaka engaphezu kuka-30.
Q2: Kungani i-leachate inzima kangaka ukwelashwa nokugcinwa?
I-leachate ithwala i-COD engu-5,000–60,000 mg/L, i-ammonia, izinsimbi ezisindayo kanye ne-pH engazinzile, kanye ne-H2S ezindaweni zegesi. I-fused enamel ye-pH 1–14 kanye nobulukhuni be-Mohs engu-6.0 ibhekana namakhemikhali nokuguguleka.
Umbuzo 3: Yiziphi izinhlobo zamareactor ezisetshenziselwa i-leachate?
Ama-reactor e-Anaerobic UASB/EGSB athatha umthwalo omkhulu we-COD futhi akhiqiza i-biogas (60–70% CH4), elandelwa amachibi e-aerobic (AO/A2O, MBR) ukuze kwenziwe i-nitrification nokucwengiswa — konke kusebenza njengamathangi e-GFS aboshwe.
Umbuzo 4: Ibuphi ubufakazi bekhwalithi okufanele bathwalwe amathangi e-leachate?
Amarekhodi okuhlolwa kweholide ye-1500V DC ngephaneli ngalinye, imibiko yobukhulu bokumboza nokunamathela, nokuhambisana ne-ISO 28765 — umgoqo obhalwe ongenazo izimbobo okufunwa ukhemikhali we-leachate.
