Chav dej yog ib qho tseem ceebchaw ua haujlwmhauv peb lub neej. Nws tuaj yeem ua tau raws li peb cov kev xav tau ntawm lub cev tab sis muaj qee qhov kev pheej hmoo ntawm kev ruaj ntseg. Xyoo 2019, ob niam txiv hluas hauv Shanghai tau tuag tom qab raug lom hauv chav dej hauv lawv lub tsev. Lub chaw tua hluav taws tau tuaj txog ntawm qhov chaw thiab siv lub tshuab ntes roj lom uas pom tias muaj peb txheej hydrogen sulfide tshaj qhov tus qauv. Tom qab nias lub pob ntawm lub tais dej, qhov siab tshaj plaws 100ppm hydrogen sulfide tau tsim tawm tam sim ntawd. Tom qab kuaj, ob tug neeg tuag vim yog lom hydrogen sulfide. Raws li cov ntaub ntawv, thaum huab cua muaj 200ppm hydrogen sulfide, nws tuaj yeem ua rau lom yog tias nqus tau 5 txog 8 feeb. Yog tias huab cua muaj 1000ppm txog 1500ppm, nws tuaj yeem ua rau tuag hauv lub sijhawm luv luv. Kev qhia txog tshuaj lom hnyav heev yog: nqus 1 txog 2 lub qhov ncauj kom tuaj yeem nres ua pa tam sim ntawd, tuag tam sim ntawd.
Ntxiv rau qhov txaus ntshai zais ntawm chav dej hauv tsev, chav dej pej xeem kuj yog "cov neeg tua neeg uas tsis pom". Hauv Kaus Lim Qab Teb, ib tug ntxhais tau mus rau chav dej pej xeem ntawm ntug kev tab sis tsis tau tawm los tom qab. Thaum nws raug pom, nws tsis nco qab thiab tuag tom qab tsev kho mob. Tom qab kev tshawb nrhiav, cov hydrogen sulfide hauv lub qhov dej ntawm chav dej pej xeem tau raug tus ntxhais nqus pa, uas ua rau tuag. Hydrogen sulfide yog cov roj tsis muaj xim, muaj tshuaj lom heev, thiab muaj kua qaub. Nws muaj ntxhiab tsw tshwj xeeb ntawm qe lwj, txawm tias qhov concentration qis ntawm hydrogen sulfide tuaj yeem ua rau tib neeg hnov tsw phem. Qhov peb hu ua "tsw chav dej" yog qhov tshwm sim ntawm kev ua ntawm cov pa roj sib xyaw no. Cov roj kuj muaj cov hydrocarbons xws li methane, uas yog qhov txaus ntshai heev.
Nrog rau kev txhim kho ntawm cov thev naus laus zis xws li kev txawj ntse ntawm cov khoom thiab Is Taws Nem ntawm Yam, cov khoom siv thev naus laus zis ntawm cov chav dej pej xeem ntse tau nthuav dav. Nws muab cov ntaub ntawv loj, Is Taws Nem ntawm Yam, kev khaws cia huab, kev suav huab, cov sensors, SIG-MESH thiab lwm yam thev naus laus zis los pab kom cov chav dej ib txwm muaj kev pom tseeb tiag tiag, kev txiav txim siab raug thiab kev ua tiav zoo. Ammonia, hydrogen sulfide, CO2, kub, thiab av noo yog cov cim qhia tseem ceeb hauv kev kuaj xyuas huab cua hauv chav dej pej xeem. Kev kuaj cov ntaub ntawv no tsis tuaj yeem sib cais los ntawm peb qhov kev ntsuas sensor. Txawm tias qee qhov chav dej pej xeem ib txwm yuav tsum tau teeb tsa: lub tswb ceeb toom roj ammonia, lub tswb ceeb toom hydrogen sulfide thiab kiv cua tso pa tawm, thiab lwm yam, kom tshem tawm cov ntxhiab tsw txawv raws sijhawm kom tsis txhob muaj kev puas tsuaj.
