Vim li cas cov pas dej hauv tsev biochemical hauv nroog tsis tuaj yeem nrog cov cua sov kom puv?

Vim li cas thiaj tsis tuaj yeem ua tsis tau cov pas dej da dej biochemical hauv tsev me me nrog cov khoom siv cua sov ua kom puv?

1, Vim li cas yuav tsis muaj biochemical pas dej ua ke puv

Lub hauv paus ntsiab lus yog hais tias cov khoom solidified decomposes nyob rau hauv qab ntawm lub tank, thiab cov hydrated tshuaj nyob rau hauv lub Upper txheej nkag mus rau hauv lub raj xa dej thiab ntws tawm. Txhawm rau tiv thaiv cov kav dej tsis sib haum thiab muab lub sijhawm hydrolysis txaus rau cov khoom muaj zog, nyob rau hauv ib txwm muaj, lub tank biochemical yog ib qho kev kho me me uas faib cov dej phwj tuaj thiab sai sai anaerobic digestes cov sludge. Lub tank biochemical yog lub hauv paus ntsiab lus ntawm kev dag ntxias thiab anaerobic fermentation, kom cov kua zaub ntws thiab nqis txhua lub sijhawm, Qhov no tau ua rau tsis txaus siab rau lub pas dej biochemical.

2, Cov dej phwj tuaj nyob muaj ntau cov quav, cov ntawv khib nyiab, thiab kab kab mob. Qhov concentration ntawm suspended solids yog nyob nruab nrab ntawm 100 thiab 400 mg / L, thiab cov concentration ntawm suspended organic teeb meem yog nyob nruab nrab ntawm 50 thiab 200 mg / L;

3, Kev sib sau cov dej phwj tuaj hauv lub tank biochemical rau 12 mus rau 24 teev tuaj yeem tshem tawm 50 feem pua ​​​​rau 60 feem pua ​​​​ntawm cov khib nyiab tshem tawm;

4, Cov sludge sau tau dhau los ua anaerobic digestion rau ntau tshaj 3 lub hlis txij thaum pib mus txog rau thaum xaus, decomposing cov organic teeb meem nyob rau hauv cov sludge mus rau hauv lub ruaj khov inorganic tshuaj, thiab converting cov perishable raw sludge mus rau hauv ruaj khov mature sludge, hloov cov qauv ntawm cov sludge thiab txo cov dej ntsiab lus ntawm sludge;

5, Vim yog cov qauv ntawm lub tank biochemical

1. Cov dej phwj tuaj yog thawj zaug tawm ntawm cov dej nkag mus rau hauv kab sib chaws, qhov twg cov khib nyiab thiab cov qe kab mob sib xyaw nrog ntau qhov sib npaug. Cov kab mob anaerobic hauv dej ntawm lub pas dej dag pib ferment thiab decompose. Cov dej phwj kho tau muab faib ua peb txheej:

1) Pasty fecal daim tawv nqaij; 2) Cov kua dej ntshiab; 3) Ib qho fecal residue.

2. Cov quav uas ntws mus rau hauv qhov chaw thib ob feem ntau tseem decomposed, thiab cov kab mob thiab cov qe cab tau raug tua;

3. Lub luag haujlwm tseem ceeb ntawm kev nkag mus rau hauv daim phiaj thib peb yog khaws cia ib ntus thiab khaws cov kua fecal uas tsis muaj teeb meem, thiab cov kua fecal uas tau sau dua los ntawm qhov pib mus rau qhov kawg ntws mus rau hauv cov kav dej hauv nroog los ntawm cov kav dej.

6, Lub hauv paus ntsiab lus tsim ua rau lub pas dej biochemical nyob mus ib txhis tsis txaus siab:

1. Kev tsim tshwj xeeb, siab thiab cuam tshuam tsis kam; 2. Compact qauv thiab kev lag luam chaw; 3. Kev tsim kho yooj yim thiab yooj yim, txuag kev ua haujlwm thiab sijhawm; 4. Nws tsis yooj yim rau xau thiab muaj kev nruj zoo; 5. Kev siv nyiaj txiag thiab kev siv nyiaj txiag; 6. Durable, nyab xeeb thiab ua haujlwm zoo.
