Cov ntaub hoob nab kev lag luam hauv kev tsim cov dej khib nyiab, cov roj khib nyiab, cov tshuaj lom neeg tuaj yeem ua rau ib puag ncig muaj txiaj ntsig, yog li ntawd ib puag ncig ib puag ncig tsis muaj kev cuam tshuam lossis tsawg dua, tau dhau los ib feem tseem ceeb ntawm kev tso zis tso quav. NTAUB NTAWV KHWV Kev lag luam rau dej dawb paug, nrog, dej ntws (biochemical oxygen thov (ss) ) Ntau, thiab muaj cov tshuaj lom, nrog cov xim muaj ntxhiab, muaj kev phom sij, kev ua liaj ua teb tsiaj thiab cov neeg nyob hauv ib puag ncig. Kev piav tau ntau xyoo, cov khib nyiab tshem tawm yuav ua rau cov dej hav zoov, thiab tsim cov roj ntsha, thiab ua kom muaj kev phom sij hydrogen lom zem.
Cov kev ua paug cov txheej txheem ua cov txheej txheem tseem ceeb hauv kev lag luam plhaw, pulping, alkali rov qab, tshuaj dawb, ntaub so dej luam thiab lwm yam. Cov khoom siv raw npaj ua cov plua plav, tawv ntoo, cov ntoo ntoo, nyom kawg; Pulping thiab alkali rov qab, tshuaj dawb tshuaj dawb, plua plav, dej khib nyiab, kua qaub, thiab lwm yam .; Ntaub hoob nab tshuaj theej dej ua cov dej dawb, txhua tus muaj cov kuab paug. Cov pa phem ntawm cov ntaub hoob nab kev lag luam rau ib puag ncig yuav muab faib ua 3 pawg ntawm cov dej muaj kuab paug (rooj 1), cov pa phem (rooj noj paug.
Cov tawv nqaij tawv yog lub pulp, pulp, cov kab av tawg, pob zeb tshauv, thiab lwm yam, thiab lwm yam. Leaching Tawm ntawm cov dej turbid kom ua rau lub cev lim dej thiab cov av hauv av. Suab lag luam tsis zoo, tseem yog qhov teeb meem loj hauv kev lag luam tso quav.
Kev tiv thaiv muaj kuab paug thiab kev tswj tau tuaj yeem faib ua ob pawg: ntawm kev kho kom tsis muaj teeb meem thiab kev kho kom tsis muaj chaw rau kev kho haujlwm.
Yashi cov ntaub hoob nab yog cov yeeb tshuaj los ntawm tag nrho cov txheej txheem lub cev. Cov txheej txheem ntau lawm tsis muaj kev phom sij rau tib neeg lub cev. Cov khoom tiav tau tsis muaj cov tshuaj uas muaj kev phom sij ntawm cov teeb meem thiab muaj kev noj qab haus huv thiab nyab xeeb. Siv cov roj kho kom tsis txhob siv roj ib txwm muaj nqos kom tsis txhob muaj pa hluav taws xob hauv huab cua. Tshem tawm cov tshuaj dawb, khaws cov xim qub ntawm cov nroj tsuag cov hmoov av, txo cov dej haus dej ntau lawm, kom tsis txhob muaj cov dej phwj tuaj, thiab tiv thaiv ib puag ncig.
