Ukukhipha amanzi e-Sludge
01
Isihlungi sebhande lokwelashwa kwe-sludge cindezela isihlabathi sokugeza insimu imishini yokukhipha amanzi ngodaka

Izici Zomkhiqizo
1) Umshini wokuhlunga webhande lokususa amanzi ngodaka unendawo ehlukile ethambekele futhi ende emise okwe-wedge ukuze kuqinisekiswe ukusebenza okuzinzile.
I-2) Ukuphelelwa amandla kwamanzi emzimbeni kunendawo enkulu, amandla okucubungula aqinile, umthamo omkhulu wokulayisha, ukusetshenziswa kwamandla okuphansi, nokusebenza kwezindleko eziphansi.
I-3) Ububanzi be-multi-roller buyancipha futhi isakhiwo sihlangene, okwandisa okuqukethwe okuqinile kwekhekhe lokuhlunga.
4) Uhlelo olusha lokutshekisa oluzenzakalelayo luthuthukisa kakhulu impilo yesevisi yebhande lokuhlunga.
5) Sebenzisa izinhlelo ezimbili ezizimele zokuwasha ngemuva.

Inqubo yokusebenza yokucindezela kokuhlunga
Yonke inqubo yokusebenza yomshini wokuhlunga ibhande ingahlukaniswa ngezigaba ezintathu eziyisisekelo: ukugeleza kwe-sludge, ukuhlunga komshini wokuhlunga amandla adonsela phansi, ukuphelelwa amandla kwamanzi emzimbeni, nokuminyanisa ukuphelelwa amanzi emzimbeni/ukuphelelwa amanzi emzimbeni.
1) I-sludge flocculation
Ngaphambi kokuthi i-sludge ikhishwe emanzini, kufanele iqale idlule inqubo ye-flocculation. I-Flocculation ibhekisela ekusebenziseni i-flocculant (okungukuthi i-polymer, i-polymer electrolyte) ukwelapha ukumiswa. Ngemuva kokuthi i-flocculant ixubene ne-sludge, izinhlayiya eziqinile ekumisweni Uhlelo lubangela ukuba i-adhesive ihlanganise futhi ihlukanise izigaba eziqinile neziwuketshezi. I-sludge i-flocculated ku-reactor flocculation, futhi isikhathi sokuhlala kwe-sludge ku-reactor flocculation cishe imizuzu engu-1 kuya kwemi-3.
2) Amandla adonsela phansi amanzi emzimbeni
Ngokusebenzisa i-flocculation, ukuphelelwa amandla kwamanzi kwe-thickener kwenziwa lapho okuqukethwe komswakama we-sludge kungu-99.3%. Umswakama we-sludge ungafinyelela ku-95-98%. Ukuze kuncishiswe ukugcwala kodaka ngaphambi kokucindezela, amanzi amaningi amahhala kufanele antante futhi amandla adonsela phansi asuswe amanzi. Indawo iyawubona lo msebenzi. I-sludge esikhwameni sokuhlunga ayithinteki amandla angaphandle. Isigaba esisebenzayo sokulayisha udaka sebhande lesihlungi sine-engeli ethile. Nge-coefficient yokungqubuzana phakathi kwebhande lesihlungi namanzi anodaka, ibhande lesihlungi sodaka lihudulela umugqa phezulu naphansi. , kunenqubo yamanzi aqongelela udaka, okuthi ngokuqhathaniswa andise isikhathi sokuphelelwa amanzi emzimbeni wamandla adonsela phansi, okwenza kube lula ukukhululwa kwamanzi amahhala. I-sludge ibuya ukuze iminyanise isikhwama sokuhlunga ibheke emuva bese ingena kuma-compactor amabhande amabili. Isebenza ngokungahleliwe kusihlungi esisodwa. Umsebenzi wayo ukuthulula udaka bese lusabalalisa ngokulinganayo phezu kwebhande lokuhlunga ukuze kuqhutshekwe nokuphelelwa amanzi emzimbeni.
3) Ukucindezela kanye nokuphelelwa amandla kwamanzi
Udaka luphelelwa amanzi ngenxa yamandla adonsela phansi. Njengoba ibhande lihamba, lingena engxenyeni yokucindezela okumise okukanxantathu phakathi kwamabhande okuhlunga, lapho licindezelwa khona futhi liphelelwe amanzi emzimbeni. Ingxenye yamanzi amahhala ebusweni be-sludge iyasuswa, bese ingena engxenyeni yokucindezela emise okwe-"S" yama-rollers ayisikhombisa. Ngenxa Ukwehliswa kodaka kanye namandla okugoba agunde akhiqizwa amandla amaningi e-viscosity phakathi kwamabhande okuhlunga akhipha amanzi amahhala ngaphakathi.

Izinhlelo zokusebenza
Ukuphrinta nokudaya udaka, udaka lwe-electroplating, udaka lokwenza iphepha, udaka lwamakhemikhali, udaka lwendle kamasipala, udaka lwezimayini, udaka lwensimbi esindayo, udaka lwesikhumba, udaka lokumba, udaka lokuphisa, udaka lokudla.
