IC high-efficiency anaerobic reactor UASB anaerobic ntauwd siab concentration dej phwj kho

Lub hauv paus qauv ntawm IC reactor yog qhia nyob rau hauv daim duab. Nws yog tsim los ntawm ob txheej ntawm UASB reactors txuas nrog hauv series. Raws li kev ua haujlwm, lub tshuab hluav taws xob tau muab faib ua 5 thaj chaw hauv qab mus rau sab saum toj: thaj chaw sib xyaw, thaj tsam thawj anaerobic, thib ob anaerobic zone, sedimentation zone thiab gas-kua cais cheeb tsam.

Kev sib xyaw ua ke: Cov dej nkag hauv qab ntawm lub reactor, granular sludge thiab av nkos-dej sib tov refluxing los ntawm cov roj-kua sib cais cheeb tsam tau zoo sib xyaw hauv cheeb tsam no.

Thawj qhov chaw anaerobic: Cov av nkos-dej sib tov tsim hauv thaj chaw sib xyaw nkag mus rau thaj chaw no, thiab nyob rau hauv qhov kev txiav txim siab ntawm cov sludge, feem ntau ntawm cov organic teeb meem tau hloov mus rau hauv biogas. Lub upwelling ntawm cov kua sib xyaw thiab kev ua phem ntawm cov biogas ua rau cov sludge nyob rau hauv cov tshuaj tiv thaiv cheeb tsam nthuav dav thiab fluidize, uas ntxiv dag zog rau kev sib cuag ntawm cov sludge thiab dej nto thiab tswj kev ua haujlwm siab. Raws li biogas ntau lawm, ib feem ntawm cov av-dej sib tov yog nqa los ntawm biogas mus rau cov roj-kua sib cais cheeb tsam nyob rau saum toj.

Gas-kua sib cais cheeb tsam: Cov biogas nyob rau hauv lub lifted sib tov yog sib cais los ntawm cov av nkos ntawm no thiab xa mus rau qhov kev kho mob system. Cov dej av nkos sib xyaw rov qab mus rau qhov sib xyaw qis tshaj plaws raws li cov yeeb nkab xa rov qab, thiab tag nrho tov nrog cov sludge thiab cov dej tuaj rau hauv qab ntawm lub reactor. Internal ncig ntawm cov kua sib xyaw yog paub.

Qhov thib ob anaerobic cheeb tsam: Tsuas yog ib feem ntawm cov dej khib nyiab kho nyob rau hauv thawj anaerobic cheeb tsam, uas yog lifted los ntawm biogas, tus so nkag mus rau lub thib ob anaerobic cheeb tsam los ntawm peb-theem separator. Cov sludge concentration nyob rau hauv cheeb tsam no yog tsawg thiab feem ntau ntawm cov organic teeb meem nyob rau hauv cov dej khib nyiab tau degraded nyob rau hauv thawj anaerobic cheeb tsam, yog li tus nqi ntawm biogas generated yog me me. Cov biogas yog nkag mus rau hauv cov pa roj-kua sib cais cheeb tsam los ntawm cov yeeb nkab biogas, ua rau muaj kev cuam tshuam me ntsis rau thaj tsam thib ob anaerobic, uas muab cov kev mob zoo rau kev tuav cov sludge.

Sedimentation cheeb tsam: Cov av nkos-dej sib tov nyob rau hauv qhov thib ob anaerobic cheeb tsam undergoes solid-kua sib cais nyob rau hauv lub sedimentation cheeb tsam. Lub supernatant yog drained deb ntawm lub qhov hluav taws xob yeeb nkab, thiab precipitated granular sludge rov qab mus rau lub sludge txaj nyob rau hauv lub thib ob anaerobic cheeb tsam. Nws tuaj yeem pom los ntawm txoj hauv kev ua haujlwm ntawm IC reactor uas lub reactor ua tiav SRT> HRT los ntawm 2-txheej peb-theem cais kom tau txais qhov siab sludge concentration; los ntawm ib tug loj npaum li cas ntawm biogas thiab loj heev cuam tshuam ntawm lub internal ncig, cov av nkos thiab dej yog tag nrho hu thiab ib tug zoo huab hwm coj hloov nyhuv yog tau.
