Khoom taw qhia
Cov cuab yeej yog tus cwj pwm los ntawm kev ua haujlwm ruaj khov, kev kho mob zoo, kev nqis peev nyiaj txiag, kev ua haujlwm tsis siv neeg, kev yooj yim ntawm kev saib xyuas thiab qhov chaw me me. Tsis tas yuav tsum muaj kev tsim kho, tsis muaj cua sov thiab kev txuag hluav taws xob.Qhov saum npoo tuaj yeem siv los ua cov av ntsuab lossis square av.Nws kuj tuaj yeem muab tso rau hauv av raws li tus neeg yuav tsum tau ua. Raws li cov khoom siv dej phwj zoo tshaj plaws, nws tau siv dav hauv kev kho cov dej phwj hauv thaj tsam ntawm cov tsev so laus, cov cheeb tsam hauv zos thiab thaj chaw nyob, industrials, resorts thiab lwm yam. Cov dej phwj tuaj tom qab kev kho mob yuav ua tau raws li lub teb chaws emission qauv los yog siv tau rau irrigation raws li cov neeg xav tau ntawm cov qauv dej.

Txheej txheem ua haujlwm
Cov dej phwj nkag mus rau hauv daim phiaj zoo ua ntej, thiab tom qab tshem tawm cov khoom me me los ntawm cov hniav nyiaj hniav kub, nws nkag mus rau hauv lub tank tswj, kho cov dej kom zoo thiab kom muaj nuj nqis, thiab tom qab ntawd tau muab tso rau hauv lub tank thawj zaug los ntawm lub tshuab nqa nqa. Cov dej khib nyiab ntws mus rau Chav Kawm A lom oxidation tank rau acidification hydrolysis thiab nitrification. Denitrification, txo qhov concentration ntawm cov organic teeb meem, tshem tawm ib feem ntawm ammonia nitrogen, thiab ces nkag mus rau O-theem lom oxidation tank rau aerobic biochemical cov tshuaj tiv thaiv. Feem ntau ntawm cov organic kuab paug yog degraded los ntawm biooxidation, thiab cov effluent ntws mus rau lub thib ob sedimentation tank rau cov khoom-kua kev kho mob. Tom qab kev sib cais, lub supernatant ntawm cov sedimentation tank ntws mus rau hauv lub tank dej ntshiab, thiab cov khoom siv tshuaj tua kab mob yog siv los tua cov kab mob phem hauv dej thiab ncav cuag tus qauv tso tawm.

Part Qhia
1. Hydrolysis acidification tank. Kev khaws cia ntawm cov dej khib nyiab hauv lub tank hydrolysis muaj kev ua haujlwm ntawm anaerobic fermentation, uas tuaj yeem txhim kho ntxiv thiab txhim kho biodegradability ntawm cov dej khib nyiab, txhim kho cov tshuaj tiv thaiv biochemical rov qab, txo lub sij hawm biochemical, txo kev siv hluav taws xob thiab kev ua haujlwm.
2. Cov dej los ntawm kev sib cuag oxidation tank hydrolytic acidification tank ntws mus rau oxidation tank rau kev kho biochemical. Lub tank oxidation tau muab faib ua ob theem. Feem ntau ntawm cov organic teeb meem hauv cov dej phwj nyoos yog degraded thiab purified ntawm no. Cov kab mob aerobic coj cov muab tub lim los ua tus nqa khoom thiab siv cov khoom organic hauv cov dej phwj tuaj ua cov zaub mov kom decompose cov organic teeb meem hauv cov dej phwj tuaj rau hauv inorganic, thiaj li ua tiav lub hom phiaj ntawm kev ua kom huv. Kev ciaj sia ntawm cov kab mob aerobic yuav tsum muaj cov pa oxygen txaus, uas yog, muaj cov pa oxygen txaus hauv cov dej phwj tuaj kom ua tiav lub hom phiaj ntawm kev kho biochemical.
3. Tom qab raug kho los ntawm kev sib chwv oxidation tank, cov effluent los ntawm cov sedimentation tank ntws mus rau hauv lub sedimentation tank los ntawm nws tus kheej mus ntxiv tshem tawm cov detached biofilm thiab ib co organic thiab inorganic me me hais. Lub tank sedimentation yog raws li lub hauv paus ntsiab lus ntawm lub ntiajteb txawj nqus. Thaum cov dej phwj uas muaj cov khib nyiab tshem tawm los ntawm hauv qab mus rau sab saum toj, qhov teeb meem yog precipitated los ntawm lub ntiajteb txawj nqus. Cov effluent tom qab sedimentation nyob rau hauv sedimentation tank yog ntau meej thiab pob tshab. Qhov qis dua yog nruab nrog thaj tsam conical sedimentation thiab sludge lifting device, thiab precipitated sludge yog nqa mus rau sludge aerobic digestion tank los ntawm huab cua nqa.
4. Cov sludge tshaj tawm los ntawm lub tank sedimentation ntawm sludge aerobic digestion tank yog digested thiab stabilized nyob rau hauv lub sludge aerobic digestion tank kom txo cov ntim ntawm sludge thiab txhim kho stability ntawm sludge. Tus nqi ntawm cov sludge tom qab aerobic digestion yog me me, yog li lub tshuab nqus tsev nqus tau siv los txuas ntxiv los ntawm kev tshuaj xyuas lub qhov ntawm cov sludge tank mus rau hauv qab ntawm cov sludge tank rau nqus, thiab tom qab ntawd nws tuaj yeem thauj tau tawm (tu ib nrab xyoo. ).
