Puas muaj cov khoom siv lub cev ntim

Lub cev tsis muaj kev cuam tshuam yog qhov tseem ceeb ntawm cov txheej txheem dej kho mob, siv los qhia huab cua lossis oxygen mus rau hauv lub cev muaj pa taws thiab pab txhawb kev ua ntu zus ntawm cov pa paug. Lub AERATION cov txheej txheem muab cov oxygen kom tau raws li cov microbygen cov pa oxygen xav tau, ua kom muaj kev cuam tshuam zoo ntawm cov organic.Lub tshuab ntsuas lub cev tsis muaj lub cev yog cov cuab yeej pabcuam uas AIDS engineers thiab cov kws kho dej tshuaj kho mob hauv kev txiav txim siab qhov xav tau lub sijhawm.Lub laij lej no siv rau hauv cov khoom siv nyiaj txiag xws li cov dej ntim, muaj kuab paug, xav tau hloov oxygen hloov kev ua haujlwm, thiab hom kev siv tshuaj aeration. Yog muaj lub peev xwm faib tau muab suav nrog kev tsim kho kom zoo dua qub, ua rau kev txhim kho cov dej kho kom zoo thaum txo cov zog siv hluav taws xob thiab cov nqi tswj hwm. Cov laij lej no ua lub luag haujlwm tseem ceeb hauv kev kho cov dej engineering, pab txhawb ib puag ncig kev khaws cia thiab cov kev npaj cov khoom siv huv.

Cov hauv qab no yog aqosionust rau koj los txheeb tawm qhov tseeb los laij cov nyiaj ntawm Aereration:

• Blue Thaiv yog tus tsim Datameter: yuav sau nyob rau hauv

• Brown: Xam cov txheej txheem cov txheej txheem

• Greener: Thaum kawg tshwm sim rau koj cov txheej txheem
