Xaiv cov li qub raws li tus txheej txheem tsim thiab xav tau. Ntau yam li qub tuaj yeem siv tau, xws li rooj vag li qub, lub ntiaj teb li qub, pob li qub, thiab npauj npaim li qub. Hauv kev tswj cov txheej txheem, solenoid li qub, pneumatic li qub, kos li qub, ib-txoj kev li qub, throttle li qub, thiab lwm yam. Kev kho dej phwj niaj hnub siv tshuab tuaj yeem muab faib ua thawj, theem nrab thiab theem nrab kev kho mob raws li qib kev kho mob. Qib ntawm kev kho dej phwj feem ntau yog txiav txim siab raws li cov dej zoo thiab qhov chaw ntawm cov dej kho.
Cov li qub siv ntawm txhua qib kuj txawv. Kev kho thawj zaug feem ntau tshem tawm cov khoom paug tawm hauv cov dej phwj tuaj, thiab feem ntau txoj kev kho lub cev tsuas tuaj yeem ua tiav cov kev cai ntawm kev kho thawj zaug. Rau cov dej phwj tuaj uas tau kho thawj zaug, BOD feem ntau tuaj yeem raug tshem tawm li ntawm 30%, uas tsis ua raws li cov qauv tso tawm.
Primary processing yog preprocessing ntawm theem nrab ua. Valves thiab yeeb nkab accessories siv xws li: riam rooj vag li qub, triple eccentric npauj npaim li qub, lim, thiab lwm yam.
Kev kho mob thib ob feem ntau tshem tawm cov pa phem (BOD, COD) hauv cov dej colloid thiab yaj hauv cov dej phwj tuaj. Tus nqi tshem tawm tuaj yeem ncav cuag ntau dua 90%, kom cov pa phem tuaj yeem ua tau raws li cov qauv tso tawm. Qhov kev tshem tawm cov khib nyiab tshem tawm tuaj yeem ncav cuag 95% thiab cov dej ntws tawm tau zoo. Cov khoom siv li qub muaj xws li muag muag npauj npaim li qub, rooj vag li qub, pob li qub, kos li qub, thiab lwm yam.
Tertiary kho ntxiv kho refractory organic teeb meem, nitrogen, phosphorus thiab lwm yam soluble inorganic teeb meem uas yuav ua rau eutrophication ntawm dej lub cev. Cov txheej txheem tseem ceeb muaj xws li kev tshem tawm cov nitrogen thiab phosphorus, coagulation sedimentation, xuab zeb pom, activated carbon adsorption, ion pauv thiab electrodialysis. Cov khoom siv xws li wafer npauj npaim li qub, rooj vag li qub, pob li qub, kos li qub, roj hmab mos pob qij txha, thiab lwm yam.
