Hydrogen sulfide yog cov roj tsis muaj xim nrog cov ntxhiab tsw ntxhiab thiab soluble hauv dej, ethanol thiab glycerol. Vim qhov tshwj xeeb ntawm cov dej phwj tuaj kho, cov pa roj malodorous uas muaj hydrogen sulfide thiab ammonia raug tsim thaum lub sijhawm tsim khoom thiab ua haujlwm. Kev tso tawm hydrogen sulfide los ntawm cov dej phwj tuaj rau hauv huab cua tuaj yeem ua rau muaj kev phom sij rau ib puag ncig thiab tib neeg kev noj qab haus huv.
Lub hauv paus ntsiab lus ntawm H2S hauv cov dej phwj tuaj kho yog cov chaw anaerobic ib puag ncig xws li kev sau zoo hauv thaj chaw muaj kev cuam tshuam, kev tswj hwm hydrolysis tank, hydrolysis sedimentation tank thiab thaj chaw kho sludge. Nws tuaj yeem tsim nyob rau hauv ob txoj hauv kev loj.
(1).Lub luag hauj lwm ntawm sulfate-txo cov kab mob (SRB) ntawm qhov tsawg REDOX peev xwm (-200mV?) Ntawm -300mV), H2, lactic acid, fatty acids, ethanol thiab lwm yam hluav taws xob ua haujlwm pub dawb, thiab NH3 yog nitrogen qhov chaw, uas txo sulfate rau H2S.
(2).Hydrolysis ntawm sulfur-muaj cov organic tshuaj, xws li cysteine, cystine, methionine, thiab lwm yam., generates H2S tom qab hydrolysis. Ntawm lawv, qhov txo qis ntawm sulfate- txo cov kab mob yog qhov ua rau H2S tseem ceeb.
Kuj tseem tuaj yeem muaj qee qhov concentration ntawm hydrogen sulfide hauv cov neeg ua haujlwm hauv chaw ua haujlwm lossis chaw so. Qhov siab tshaj plaws tso cai ntawm hydrogen sulfide hauv huab cua yog 10 mg / m ³ (7 ppm), thiab cov concentration ntawm hydrogen sulfide nyob rau hauv qee chav kho mob ntawm cov dej phwj tuaj yeem qee zaum ncav cuag kaum rau pua pua ppm. Thaum cov concentration siab dhau lawm, nws tuaj yeem ua rau cov tsos mob xws li mob taub hau, kiv taub hau, xeev siab thiab ntuav hauv tib neeg lub cev. Hauv cov xwm txheej hnyav dua, cov tsos mob ntawm qhov muag khaus lossis mob ntsws pulmonary edema tuaj yeem tshwm sim.
Muab qhov teeb meem tseem ceeb ntawm hydrogen sulfide rau tib neeg lub cev, nws yog ib qho tsim nyog yuav tsum kuaj xyuas cov ntsiab lus ntawm hydrogen sulfide roj hauv cov chaw kho dej hauv lub sijhawm tiag tiag, txhawm rau ua kom muaj kev tiv thaiv tsim nyog tam sim thiab txo qis kev puas tsuaj ntawm hydrogen sulfide rau tib neeg lub cev.
Yog li ntawd, lub industrial h2s gas ntesyog ib qho kev tiv thaiv uas cov chaw kho dej phwj yuav tsum tau ua. Hydrogen sulfide sensors tuaj yeem saib xyuas qhov concentration ntawm hydrogen sulfide hauv huab cua hauv lub sijhawm. Thaum cov pa roj hydrogen sulfide ntau tshaj qhov muaj kev nyab xeeb, lawv tuaj yeem ceeb toom rau tib neeg kom tiv thaiv - kab mob ntsuas hauv lub sijhawm thiab tseem tiv thaiv tus kheej thiab cov khoom muaj kev nyab xeeb ntawm cov chaw kho dej phwj tuaj.
