Tom qab kho thawj zaug, qhov tshem tawm cov khib nyiab tawm yog 70% ~ 80%, thaum tshem tawm cov biochemical oxygen demand (BOD) tsuas yog kwv yees li 25% ~ 40%, qhov dej ntawm cov dej khib nyiab tsis siab.

Txoj hauj lwm ntawm kev kho mob theem ob yog tshem tawm cov organic kuab paug ntawm cov dej khib nyiab. Siv BOD ua piv txwv. Tom qab kev kho ntxiv, lub BOD nyob rau hauv cov dej khib nyiab
