"【XJY Environmental Technology】 Kev tshuaj xyuas tag nrho ntawm kev kho dej hauv tsev nruab nrab: cov lus qhia dav dav los ntawm qhov chaw mus rau cov kev daws teeb meem zoo"

Medium-Scale Domestic Wastewater Treatment 1. Hom dej khib nyiab: - Cov dej khib nyiab hauv tsev: Los ntawm tsev neeg, suav nrog chav dej, dab dej, da dej thiab ntxhua khaub ncaws. - Cov dej khib nyiab lag luam: Tsim los ntawm cov chaw so, tsev so thiab tsev noj mov, qhov chaw npaj zaub mov thiab kev pabcuam qhua tuaj yeem yog qhov chaw ntawm cov khoom pov tseg thiab tshuaj lom neeg ntxiv. - Industrial Wastewater: Feem ntau yog los ntawm cov txheej txheem tsim khoom thiab tuaj yeem muaj cov kab mob sib txawv raws li kev lag luam. 2. Cov yam ntxwv ntawm cov dej khib nyiab: - Organic Matter: Cov khoom loj tuaj yeem los ntawm cov khoom pov tseg, cov tshuaj ntxuav tes thiab cov pov tseg tib neeg. - Khoom noj khoom haus: Nitrogen thiab phosphorus qib tuaj yeem nce siab, yuav tsum tau kho kom tiv thaiv algae blooms hauv dej tau txais. - Chemical Contaminants: Nyob ntawm kev koom tes hauv kev lag luam, cov hlau hnyav, roj thiab lwm yam tshuaj muaj nyob. 3. Cov txheej txheem kho mob: - Kev kho mob tseem ceeb: Kev tshuaj ntsuam xyuas thiab degritting kom tshem tawm cov khib nyiab loj thiab cov khib nyiab. - Kev Kho Mob Tseem Ceeb: Sedimentation tanks tshem tawm cov khib nyiab thiab txo BOD (biochemical oxygen xav tau). - Kev Kho Mob Thib Ob: Cov txheej txheem lom neeg xws li cov activated sludge lossis biofilm reactors tuaj yeem txo cov organic teeb meem thiab cov as-ham ntxiv. Qhov no tuaj yeem suav nrog cov txheej txheem aerobic thiab anaerobic. - Kev kho mob Tertiary: Cov kev kho mob siab tshaj plaws xws li pom, tshuaj tua kab mob (chlorination lossis UV), thiab kev tshem tawm cov khoom noj kom ntseeg tau cov dej zoo. 4. Cov Kev Sib Tw: - Cov nqi khiav tsis zoo: Cov neeg nyob hauv tsev so sib txawv lossis cov neeg tuaj xyuas raws caij nyoog tuaj yeem ua rau muaj kev hloov pauv, ua rau kev kho mob tsis tu ncua. - Pollutant ntau haiv neeg: Cov chaw sib txawv tuaj yeem tso cov pa phem tshwj xeeb, xav tau cov kev kho mob hloov tau yooj yim thiab hloov tau. - Kev cai: Ua raws li cov cai hauv cheeb tsam txog kev tso dej pov tseg tuaj yeem ua haujlwm nyuaj, tshwj xeeb tshaj yog thaum cov dej khib nyiab hauv tsev thiab kev lag luam sib xyaw. 5. Cov kev coj ua kom ruaj khov: - Kev siv dej rov ua dua: Kev siv cov tshuab uas rov siv cov dej khib nyiab rov qab los rau kev tso dej los yog tso dej hauv chav dej tuaj yeem pab txo qhov xav tau dej tag nrho. - Green infrastructure: Siv cov txheej txheem kev kho mob xws li cov av ntub dej ua haujlwm tuaj yeem txhim kho kev kho mob thiab txhawb nqa biodiversity. - Kev koom tes hauv zej zog: Koom nrog cov neeg nyob hauv zos thiab cov lag luam hauv kev txuag dej tuaj yeem ua rau muaj txiaj ntsig zoo ntawm cov tswv yim tswj dej khib nyiab.

Xaus Kev tswj cov dej khib nyiab zoo hauv nruab nrab cov dej khib nyiab hauv tsev, tshwj xeeb tshaj yog nyob rau hauv cov chaw sib xyaw siv xws li chaw so thiab thaj chaw nyob, yog qhov tseem ceeb rau kev tiv thaiv pej xeem kev noj qab haus huv thiab ib puag ncig. Ib qho kev sib koom ua ke uas siv cov thev naus laus zis kho kom tsim nyog thiab hais txog kev ruaj ntseg tuaj yeem pab daws cov teeb meem tshwj xeeb uas nthuav tawm los ntawm cov dej khib nyiab sib txawv no.
