XJY Phau Ntawv Qhia Txog Kev Tswj Xyuas Sludge: Xauv Lub Peev Xwm ntawm Kev Siv Hluav Taws Xob Hluav Taws Xob, Dewatering, Qhuav, & Dust Control
Cov XJY sludge kev kho mobtxheej txheem muaj ntau theem tseem ceeb, nrog rau kev lom neeg Deodorization, sludge dewatering, sludge drying, thiab cov khoom siv tshem tawm plua plav.
Biological Deodorization
Lub Hom Phiaj: Txhawm rau tshem tawm cov malodorous tebchaw thiab cov kab mob los ntawm sludge los ntawm cov txheej txheem lom neeg.
Txheej txheem txheej txheem:
Bioleaching Technology: Qhov no suav nrog inoculating concentrated sludge (kwv yees li 97% dej ntsiab lus) nrog cov kab mob nyuaj thiab ntxiv cov as-ham hauv ib qho piv txwv.
Raug rau Aeration: Cov sludge raug rau aeration nyob ib ncig ntawm 48 teev, uas txo cov pH mus rau 2-3, ua tiav cov txheej txheem bioleaching.
Mechanism: Lub acidic ib puag ncig tsim los ntawm bioleaching microorganisms ua rau hlau sulfides hloov mus rau hauv cov hlau sulfates soluble, tso cov hlau hnyav rau hauv cov kua theem. Cov txheej txheem no tseem tshem tawm sludge tsw thiab tua cov kab mob, txhim kho sludge dewaterability.
Cov txiaj ntsig: Tom qab bioleaching, sludge ntxhiab raug tshem tawm, cov kab mob raug tua los yog inhibited, thiab sludge dewaterability yog txhim kho. Cov sludge tus nqi fertilizing thiab tus nqi calorific tseem tsis hloov pauv ntau.
duab 1 Biodeodorization
Lub Hom Phiaj: Txhawm rau txo cov dej ntawm cov sludge, ua kom yooj yim rau kev lis thiab pov tseg.
Cov Txheej Txheem Feem Ntau:
Lub ntiajteb txawj nqus Thickening: Ua tiav nyob rau hauv sedimentation tso tsheb hlau luam los ntawm tsim ib tug high-concentration sludge txheej. Haum rau thawj sludge, tshuaj sludge, thiab biofilm sludge.
Huab cua Flotation Thickening: Siv cov npuas me me los txuas rau sludge hais, txo lawv qhov ntom thiab yuam lawv ntab. Qhov zoo tshaj plaws rau cov tshuab me me ua kom cov sludge.
Centrifugal Thickening: Raws li qhov sib txawv ntawm lub ntiajteb txawj nqus ntawm cov khoom thiab cov kua. Muaj txiaj ntsig zoo tab sis raug nqi, tsim nyog rau cov chaw kho dej khib nyiab loj.
Mechanical Dewatering: Siv dav thoob ntiaj teb, siv cov khoom siv xws li lub tshuab nqus tsev lim, siv cov xovxwm lim, thiab cov centrifuges. Belt xovxwm lim yog nrov vim lawv siv zog tsawg, ua haujlwm tsis tu ncua, thiab siv tau yooj yim.
duab 2 Sludge dewatering
Lub Hom Phiaj: Txhawm rau txo qis cov dej noo ntawm cov sludge, ua kom yooj yim rau nws khaws cia, kev thauj mus los, thiab cov peev txheej rov qab los.
Tshuab ziab khaub ncaws:
Direct Cua sov: Siv cov cua kub xws li cua kub los yog chav dej ncaj qha rau cov sludge.
Indirect cua sov: Thaum tshav kub kub pauv los ntawm lub tshav kub exchanger yam tsis muaj kev sib cuag ncaj qha nrog cov sludge, txo qhov kev pheej hmoo ntawm kev kis kab mob.
Hybrid Cua sov: Muab cov cua sov ncaj qha thiab tsis ncaj rau kev ua haujlwm zoo.
Hom tshuab ziab khaub ncaws:
Drum Dryers: Ob qho tib si ncaj qha thiab tsis ncaj yog muaj, siv roj lossis biogas ua qhov cua sov.
Disk Dryers: Kab rov tav thiab ntsug multi-disk tsim, siv chav lossis roj thermal rau cua sov.
Belt Dryers: Ua haujlwm ntawm qhov kub qis mus rau nruab nrab, haum rau kev ziab tag nrho thiab ib nrab.
Fluidized Bed Dryers: Sludge yog qhuav yam tsis muaj pretreatment, siv lub txaj fluidized rau cov cua sov sib xws.
duab 3 Sludge drying
Lub Hom Phiaj: Txhawm rau tshem tawm cov plua plav tawm thaum lub sij hawm sludge kom qhuav, ua kom cov pa huv si thiab cov khoom siv tiv thaiv.
Hom Kev tshem tawm plua plav:
Lub hnab lim: Sau cov plua plav los ntawm cov hnab lim, nrog rau hom kev sib tsoo tshuab, rov qab tshuab tshuab, thiab pulse dav hlau tu. Siv tau rau kev sib cais cov hmoov av zoo.
Cartridge Filters: Hais txog cov teeb meem nrog cov plua plav nyuaj-rau- lim plua plav thiab siab pom kev tshaj tawm, txhim kho cov nqi khiav lag luam thiab kev pom zoo.
Cyclone Separators: Siv lub zog centrifugal los cais cov plua plav tawm ntawm huab cua, feem ntau siv hauv kev lag luam nrog cov hmoov av ntxhib.
Cov Scrubbers ntub dej: Koom nrog cov tshuaj tsuag dej los yog lwm yam kua los ntes cov plua plav, tshem tawm cov plua plav thiab cov pa phem.
Electrostatic Precipitators: Ib zaug siv dav tab sis maj mam hloov vim kev ua haujlwm tsis txaus tiv thaiv cov qauv kev lag luam emission tam sim no.
Advanced Technologies:
Multi-Effect Condensation Dehumidification Heat Pump Drying: Xws li cov thev naus laus zis ua haujlwm los ntawm qee yam khoom siv hluav taws xob qis qis, muab kev ua haujlwm siab, tsis muaj emissions, thiab tshem tawm cov plua plav tawm.
Hauv kev xaus, cov txheej txheem kev kho cov sludge suav nrog kev siv tshuaj lom neeg deodorization, sludge dewatering, sludge kom qhuav, thiab tshem tawm plua plav, txhua theem ua rau muaj kev nyab xeeb, muaj txiaj ntsig, thiab kev tswj hwm ib puag ncig ntawm sludge.
