Qhov zoo ntawm cov khoom siv kho dej phwj hauv nroog

Kev kho cov dej phwj hauv nroog yog qhov yooj yim rau kev ua, tab sis cov khoom siv kho cov dej phwj nyob deb nroog kuj muaj teeb meem ntau dua, yog li qhov chaw yuav muaj ntau dua, tab sis kev kho mob tuaj yeem pib hauv cov chaw pej xeem xws li tsev kawm ntawv, tsev kho mob, tsev so, thiab lwm yam. Tam sim no cia peb tham txog cov txiaj ntsig ntawm kev siv cov khoom siv dej phwj hauv nroog.

1. Txuag qhov chaw, tsis txhob siv hectares ntawm qhov chaw. Cov khoom siv kho dej hauv tsev tuaj yeem muab faus rau hauv qab ntawm qhov chaw, thiab saum npoo tuaj yeem siv los ua ntsuab lossis square av, yog li cov cuab yeej yuav tsis tau txais qhov chaw saum npoo av, tsis tsuas yog nws yuav tsis tau muab tso rau hauv tsev, tab sis nws yuav yeej tsis xav tau ntau thiab ntau dua tshav kub rwb thaiv tsev txias tiv thaiv ntsuas.

2. Kev pabcuam lub neej ntawm cov khoom siv dej phwj hauv nroog tuaj yeem ncav cuag 15 xyoo. Cov khoom siv kho dej phwj yog hloov mus rau lub pas dej ua ke, uas yog cov qauv sib sib zog nqus faus hlau.

3. Zoo decontamination nyhuv thiab ruaj khov dej zoo. AO cov txheej txheem kev kho mob lom neeg hauv cov khoom siv dej phwj tuaj koom ua ke siv cov khoom siv hluav taws xob sib txuas nrog oxidation tank, thiab nws cov txiaj ntsig zoo sib piv rau qhov sib xyaw ua ke ntawm theem nrab thiab qib thib ob series lom oxidation tso tsheb hlau luam. Piv nrog rau cov activated sludge tank, lub ntim yog ntau loj, thiab adaptability rau ntau yam dej zoo yog tsis muaj zog heev. Lub effluent zoo yog tshwj xeeb yog ruaj khov thiab yuav tsis ua rau sludge bulking.

Cov chaw tsim khoom lossis cov chaw lag luam uas siv cov khoom siv dej phwj tuaj nyob deb nroog yuav ntsib teeb meem xws li cov khoom siv tsis ruaj khov thiab cov khoom siv dej seepage. Cia wb mus saib tej kev txhaum thiab kev daws teeb meem.
1. Cov dej ntws tawm tsis ruaj khov. Yog tias cov khoom siv kho cov dej phwj nyob deb nroog tsis tuaj yeem tsim cov dej ruaj khov, peb tuaj yeem tshawb xyuas seb cov kav dej sib txuas lus puas tau hu rau oxidation tank, sedimentation tank, tshuaj tua kab mob thiab sludge tank raug thaiv. Feem ntau, plugs yog siv los ua peb-seem ntxiv cov ntaub ntawv rau biofilms puas los yog puas projectiles ntawm cov khoom.

2. Lub aeration ntawm kev sib cuag oxidation tank yeej tsis sib xws. Yog hais tias lub aeration ntawm cov kav dej phwj nyob deb nroog nyob rau hauv kev sib cuag nrog lub oxidation tank yeej tsis zoo ib yam, peb yuav xyuas seb lub qhov hluav taws xob valve ntawm lub aeration kiv cua ntawm cov cuab yeej nyob rau hauv ib tug ruaj khov txoj hauj lwm kom paub meej tias lub aeration lub taub hau ntawm cov khoom nyob rau hauv ib tug aeration. txoj hauj lwm ruaj khov. puas, nyuaj ua hauj lwm stably.

3. Cov nyhuv tiv tauj ntawm biofilm tsis sib xws. Hauv qhov no, koj tuaj yeem tshawb xyuas seb lub aeration ntawm cov cuab yeej hu rau lub tank oxidation yog ib yam, thiab seb cov sludge nyob rau hauv lub thib ob sedimentation tank yog pumped rau hauv lub tank; Yog tias qhov ntsuas qhov sib piv yog qhov ruaj khov, ces cov khoom tsim nyog xws li qab zib thiab urea tuaj yeem muab ntxiv rau hauv lub pas dej oxidation.

4. Qhov zoo ntawm cov effluent tau tsis tsim nyog. Qhov xwm txheej no feem ntau yog vim qhov dej me me, thiab cov cuab yeej siv tau yooj yim rau kev kho dej phwj ruaj khov; los yog lub aeration ntawm cov cuab yeej nyob rau hauv kev sib cuag nrog lub oxidation tank yeej tsis tau zoo ib yam li los yog nres rau ib tug luv luv lub sij hawm, thiab cov biofilm yuav tsum tau re-cultivated.
