Tsev Kho Mob Ua Haujlwm Kev Tshawb Fawb Kev Kawm Txuj Ci

Project Ovepiew

Fuyang neeg lub tsev kho mob yog ib lub tsev kho mob kho mob muaj kev sib raug zoo rau kev noj qab haus huv, kev qhia, kev tshawb fawb, kev tiv thaiv, kev kho mob, thiab kev pabcuam xwm txheej ceev, thiab cov kev pabcuam xwm txheej kub ntxhov. Nws muaj 21 lub chaw kuaj mob, chav kuaj mob hauv tsev kho mob, 650 tus neeg ua haujlwm tau tso cai, thiab 827 cov neeg ua haujlwm hauv 300,000 tus neeg tuaj saib xyuas txhua xyoo ntawm 300,000 xyoo dhau los. Raws li lub tsev kho mob nthuav dav, cov dej khib nyiab tau nce ntau. Txhawm rau tiv thaiv ib puag ncig cov pa phem, tiv thaiv kev noj qab haus huv rau kev noj qab haus huv, tsev kho mob pionewatered kev kho mob hauv cheeb tsam kev noj qab haus huv hauv zos kom ntseeg tau tias effluent li cas.

1. Dej Ntau

Tsev kho mob kom muaj dej tso dej nyob ntawm cov yam ntxwv xws li xws li cov nplai khomob, cov cuab yeej khomob, cov neeg ua neeg siab, thaj av, thiab kev tswj hwm. Raws li ib lub tsev kho mob nruab nrab ntawm lub tsev kho mob uas muaj chav tsev noj mov, chav dej, thiab khw muag khoom, nws cov khoom siv tsis muaj zog yog kwv yees li700 m³/d (Peaking Factor K =2.0}} - 2.2). Kev suav nyiaj rau yav tom ntej, tus qauv tsim muaj peev xwm tau teeb tsa ntawm800 m³/d.

2. Dej Zoo

Tsev kho mob kom tau txais cov dej hauv tsev kho mob heev, nrog cov cim thiab cov kab mob hauv tsev tab sis muaj cov kab mob ntxiv, cov kab mob, cov khoom siv cab) thiab cov khoom muaj kev phom sij. Tus qauv tsim qauv:

• Tus ntses: 300 mg / l
• Lub cev: 150 mg / l
• Ss: 160 mg / l
• pH: 7–9
• Nkhaus dej khov: >2.4 × 10 teev cfu / l

3. Txo cov qauv

• Qhov project ua raws nrog Suav cov txheej txheem pov tseg kom ua tiav cov qauv tso tawm (GB 8978-1996) Qib I:
• Tus ntses <100 mg/L
• Lub cev <30 mg/L
• Ss <70 mg/L
• pH: 6–9
• Nkhaus dej khovTsawg dua los yog sib npaug rau 500 cfu / l
• Tag nrho cov tshuaj chlorineTsawg dua los yog sib npaug rau 0.5 mg / l (post-dechlorination).

Txheej Txheem Flow

Dej los ntawm cov pawg ntseeg (ua haujlwm ua ntej rau hauv cov chaw tso tsheb hlau luam), cov chaw ua haujlwm hauv tsev, thiab lwm yam dej ntws ntxiv ntws los ntawm aTeb Rwb Kho TshuabTxhawm rau tshem cov khoom siv coarse, ces nkag mus rau ib qhoVaj Huam Sib Luagrau homogenization. Submersible twj nqa cov dej rau ibAnaerobic Hydrolysis Tank, qhov twg microbes ib nrab ntawm cov organics thiab txhim kho biodegradity thaum kev zom zaub mov rov qab los ntawm tus lej yooj yim.

Lub effluent ntws mus rau hauv aLub Tankiological Biological OxidationNrog rau kev sim ua kom muaj los ntawm lub tshuab tawg, qhov twg aerobic microbes tshem tawm cov orgics ntau tshaj plaws. Cov cawv cawv sib cais cais hauv aThib ob hais kom meej, thiab lub effifent effluent yog tsau tshuaj nrog chlorine dioxide hauv aKhoom Siv Hluav Taws XobUa ntej tawm.

• Sludge kev tswj hwm: Piav qhia meej sludge rov qab mus rau lub anaerobic tank rau kev zom. Tshaj dhau kev swb yog dewatered ntawm aphaj-thiab-ncej lim xovxwm, thiab lub taub ncuav mog qab zib lim (nrog rau kev ntsuam xyuas grit) yog cov nqaij tawg ua ntej tso tawm chaw pov tseg.
• Txheej Txheem Dogram: Saib daim duab 1-1.

Qhov ntsuas tseem ceeb & kev ua tau zoo

1. Cov cim nyiaj txiag

• Lub peev xwm:800 m³/d
• Tag nrho cov peev txheej:¥530,000 (¥663/m³)
• Hneev taw:0.34 m²/m³
• Tus nqi ua haujlwm:¥0.47/m³

2. ENVironmental Cov Nyiaj Pab

Kev txo txhua xyoos:

• Tus ntses: 27.7 tons
• Lub cev: 11.87 Tons
• Ss: 12.56 tons

3. Kev soj ntsuam cov txiaj ntsig(Feb 2002)

Tom qab 3 lub hlis ntawm kev ua haujlwm hauv kev sim, txhua qhov tsis tau ntsib GB 8978-1996 Theem I:

Tseem Ceeb

1. Anaerobic Hydrolysis Tank:

• Txhaum macromolecules, converts tsis-soluble cov organics, thiab txhim kho biodegradabe.
• Slude zom zom zom cov ntaub npog tsis zoo (tsis muaj sludge tso tawm txij li xyoo 2001).

2. Electrolytic Chlorine Dioxide Generator:

• Tebchaw ntsev / Dej / Hluav Taws Xob Hloov Kev Nyab Xeeb Sodium Choppor Heev.
• Kev tshuaj tua kab mob zoo tshaj (vs. chlorine / hypochlorite) tsis muaj kev tsim kev phom sij.
• Brophroduct alkali tau siv rau ntxhua khaub ncaws, txo cov tshuaj ntxuav tes.

3. TB / TA VIAS Fillers:

• Yooj yim installation, dawb-dub tsim, thaj chaw siab, thiab kev tsim kho biofilm sai.

4. Cov Txheej Txheem Zoo:

• Kev ua haujlwm ruaj khov, muaj txiaj ntsig zoo, tus nqi qis (capex / opex), thiab ntsuas rau cov tsev kho mob zoo sib xws.
