Puas yog ntxiv polyaluminium chloride (PAC) thiab polypropylene (PP) ib txwm ua rau kev kho mob zoo dua?
Tsis muaj!
Qhov ntau npaum ntawm PAC thiab PP yuav tsum tau txiav txim siab raws li qhov xwm txheej ntawm cov dej tau kho. Kev noj ntau dhau yuav tsis ua rau muaj txiaj ntsig kev kho mob zoo dua thiab tuaj yeem ua rau nce nqi lossis ua rau lwm yam teeb meem.
Yog li, qhov ntawd txhais tau tias koj tsis tuaj yeem ntxiv ntau dhau? Tsis tas li. Qhov tseem ceeb yog "dosage." Ntxiv "me me" ntawm PAC thiab PP muaj ntau yam txiaj ntsig, thaum "ntau" ntau npaum li cas muaj ntau qhov tsis zoo.
Cov txiaj ntsig ntawm kev ntxiv me me ntawm PAC:
1. Ntau cov colloidal degumming, tag nrho flocculation ntawm nplua suspended solids, clearer effluent, thiab qis turbidity.
2. Txhim kho kev tshem tawm cov xim, hnyav hlau, thiab phosphates.
3. Ua kom muaj zog tiv thaiv cov dej tsis zoo; tsis tshua muaj sludge vau thaum influent suspended solids dheev nce.
Cov txiaj ntsig ntawm kev ntxiv me me ntawm PP:
1. Denseer, larger flocs, faster settling speed, and better sludge-water separation.
2. Ua kom cov sludge viscosity ua rau dewatering yooj yim dua thiab txo cov sludge to los ntawm cov ntaub lim.
3. Ntau compacted scum ua rau huv effluent los ntawm flotation tank.
Disadvantages ntawm Ntau Tshaj Polyaluminium Ntxiv:
1. Tus nqi reagent tau nce ntxiv.
2. Feem ntau cov txhuas ion nyob rau hauv cov dej ua rau cov supernatant ua turbid, ua rau cov dej dawb turbid.
3. COD nce ntxiv thiab ntau dhau ntawm txhuas qib inhibit qhov kev kho mob lom.
4. Kev tawg ntawm cov sludge ntim ntau dhau ntawm cov sludge depressor, ua rau cov dej noo ntau dua hauv cov ncuav mog qab zib sludge.
Disadvantages ntawm Ntau Tshaj Polypropylene Ntxiv:
1. Tus nqi reagent tau nce ntxiv.
2. Cov dej viscosity nce siab heev, ua rau cov supernatant ua viscous, nthuav tawm cov phenomena stringy, thiab nce effluent COD.
3. Cov nplaum nplaum ntau dhau ua rau cov sludge ua raws li cov ntaub lim dej thiab cov kav dej txhaws, ua rau cov sludge depressing ntau dua.
4. Cov polymers ntau dhau nkag mus rau hauv lub tank kho cov kab mob lom, cuam tshuam rau cov zej zog microbial thiab ua rau tsis muaj foaming thaum lub sij hawm aeration.
Tswv yim:
1. Ua qhov me me - ntsuas dej ntsuas ntsuas kom pom qhov tsim nyog npaum li cas rau qhov chaw tshwj xeeb. Tsis txhob dig muag ntxiv raws li kev paub dhau los.
2. Polyaluminium chloride yuav tsum tau muab ntxiv ua ntej kom nws tuaj yeem ua rau muaj kev cuam tshuam thiab tsim cov flocs zoo ua ntej ntxiv polyacrylamide kom nrawm floc aggregation thiab sedimentation. Rov qab qhov kev txiav txim los yog sib tov los yog haphazardly ntxiv cov tshuaj, txawm tias muaj koob tshuaj loj, yuav tsis ua tiav qhov xav tau flocculation thiab dej purification nyhuv.
3. Kho qhov ntau npaum li cas me ntsis kom tsis txhob muaj kev hloov pauv hauv cov dej zoo. Thaum ntsib kev hloov pauv hauv cov dej tsis zoo, kho cov koob tshuaj maj mam thiab sib npaug, tsis txhob muaj qhov nce loj hauv ib zaug uas tuaj yeem cuam tshuam qhov system.
