Daim Ntawv Thov Cov Chaw Kho Dej Phwj Tuaj hauv Beijing

Qee lub chaw kho dej phwj hauv Beijing yog ib qho ntawm cov kev tsim kho vaj tse uas tau tsim los daws cov teeb meem kho dej phwj hauv nroog thiab thaj chaw ib puag ncig. Nws tau ua tiav thiab muab tso rau hauv kev siv thaum Lub Rau Hli 2009. Tam sim no, thaj chaw nruab nrab ntawm lub nroog siv lub tshuab ua ke tsis muaj chaw kho dej phwj. Cov dej phwj tsis raug kho thiab tso tawm mus rau hauv tus dej los ntawm cov kav dej sib koom ua ke, ua rau muaj kuab paug rau cov dej uas twb muaj lawm. Nrog rau kev ua kom nrawm ntxiv ntawm kev tsim kho hauv nroog, cov pej xeem hauv nroog tab tom txhim kho sai, thiab cov dej phwj nce ntxiv txhua hnub. Tsis tas li ntawd, txhawm rau tiv thaiv cov dej hauv nroog, ua ib feem tseem ceeb ntawm cov kev tsim kho hauv nroog, nws yog qhov tsim nyog los tsim lub chaw kho dej phwj hauv lub nroog no. Yuav muaj ib lub pas dej tshiab uas tsim los nyob ib puag ncig lub chaw kho dej phwj, thiab cov dej kho yuav raug siv ua qhov chaw ntawm cov dej phwj lossis tso tawm mus rau hauv ib qho dej. Qhov project scale yog 20000 m3 / d yav tom ntej thiab 30000 m3 / d yav tom ntej.

Lub tsev tseem ceeb muaj xws li: chav twj tso kua dej (xws li chav grille), chav cyclone grit, chav ntxuav xuab zeb, qhov chaw oxidation, lub tank sedimentation, chav twj sludge, chav tshuab dewatering sludge thiab lub tank cia av nkos, cov tsev khaws sludge, cov kav dej tua kab mob UV, cov chaw thiab cov qauv deodorization, thiab cov chav dosing; lwm lub tsev thiab cov qauv muaj xws li chav hloov pauv tseem ceeb, lub tsev dav dav, pas dej tua hluav taws thiab chav twj tso kua mis, chav twj tso kua mis kub, tsev rau khoom, chav txij nkawm, thiab chav sib txuas lus. Lub tsev dav dav muaj chav tswj hwm hauv nruab nrab thiab chav kuaj mob, uas tuaj yeem saib xyuas thiab tswj ntau yam ntaub ntawv. Yog li cov neeg ua haujlwm hauv tsev tuaj yeem hloov kho cov txheej txheem raws sijhawm. Peb lub chaw siv txoj kev oxidation ditch activated sludge rau kev kho mob thib ob ntawm cov dej phwj tuaj, suav nrog cov kev xav tau rau phosphorus thiab nitrogen tshem tawm.

Ucov khoom hu nkauj:

Shanghai BOQU Instrument muab kev sib xyaw ua ke ntawm kev saib xyuas tsis siv neeg thiab kev saib xyuas phau ntawv rau qhov project no. Kev saib xyuas tsis siv neeg daws teeb meem kev ua haujlwm thiab kev saib xyuas ntawm lub tuam txhab rau cov dej phwj tuaj thiab ua kom muaj kev ruaj khov thiab kev ntseeg siab ntawm cov dej zoo thaum lub sijhawm kho cov txheej txheem ntawm lub tuam txhab. Kev saib xyuas phau ntawv uas tau muab tso rau hauv Beijing Urban Drainage Monitoring Station ua kev saib xyuas. Los ntawm kev saib xyuas thiab tswj cov dej zoo kom ntseeg tau tias cov dej zoo ruaj khov thiab txhim khu kev qha.
