Nyob rau hauv xyoo tas los no, muaj ntau qhov xwm txheej tawg hauv cov chaw kho dej phwj tuaj. Cov khoom tseem ceeb thiab kev tsim muaj peev xwm ntawm lub tuam txhab koom nrog qhov xwm txheej yog 10, 000 tons ntawm glyphosate, 3, 000 tons ntawm methanasone, 100 tons ntawm methyl disulfonone raw tshuaj synthesis project thiab 9, {{ 6}} tons ntawm glyphosate intermediate diethyl methyl phosphite ib xyoos twg. Vim li cas thiaj li tawg ntawm cov dej phwj tuaj kho cov nroj tsuag tsis tu ncua, qhov no lanzhou cov tshuaj tua kab kev lag luam dej phwj kho rhiav tawg thiab dab tsi yuav ua rau muaj kev cuam tshuam?
Tshuaj lom neeg chaw ua si dej phwj kho nroj tsuag los yog dej phwj kho rhiav rhiav tawg tshwm sim ntau zaus, dej phwj kho cog los yog dej phwj kho rhiav tawg feem ntau muaj peb lub sij hawm.
Ntawm qhov tod tes, cov dej phwj tuaj kho anaerobic theem yuav tsim cov methane, hydrogen sulfide thiab lwm cov roj hluav taws xob, cov roj hluav taws xob sib xyaw nrog huab cua hauv lub thawv tshuaj tiv thaiv muaj kev pheej hmoo ntawm kev tawg. Ntawm qhov tod tes, ib feem ntawm cov dej phwj tuaj muaj cov roj hluav taws xob lossis cov kua dej, uas yooj yim rau kev sib xyaw nrog huab cua los tsim cov khoom tawg.Thib peb, yog tias lub tsev kho mob dej phwj tuaj rau hauv ib feem ntawm cov thawv ntim khoom siv hluav taws xob, cov chaw hauv lossis ib puag ncig kev ua haujlwm tua hluav taws, yog tias tsis ua raws li cov qauv kev ua haujlwm, nws kuj yog ib qho yooj yim ua rau tawg tawg.Cov dej khib nyiab tawm los ntawm cov chaw lag luam tshuaj muaj peev xwm muaj cov kua dej ntau ntawm cov organic pov tseg, uas tuaj yeem tsim cov khoom tawg yooj yim thaum sib xyaw nrog huab cua hauv qee qhov xwm txheej.
Nws yog manifested nyob rau hauv cov nram qab no yam:
Ua ntej, yog tias cov cuab yeej siv tau zoo li airtight kev puas tsuaj los yog dhau los ntawm kev ua txhaum ntawm kev ua haujlwm, cov kua hluav taws xob thiab cov khoom tawg yooj yim nkag mus rau hauv cov dej phwj tuaj, uas tuaj yeem tawg.Qhov thib ob, nyob rau hauv qhov kub thiab txias, yuav ua rau cov dej phwj tuaj kub. Qhov siab ntawm cov organic pov tseg vapors sib xyaw nrog huab cua tuaj yeem ua rau tawg hauv qhov chaw kaw lossis chaw.Thib peb, cov pa hluav taws kub thiab tawg ua los ntawm cov chaw kho dej phwj yog cov roj sib xyaw ua ke. Piv txwv li, qee cov txheej txheem uas tsim cov roj feem ntau nrog hydrogen sulfide kuj tseem muaj cov pa roj carbon monoxide thiab methane; Qee cov biogas, methane raws li cov txheej txheem txuas, tseem yuav muaj hydrogen sulfide.Yog li ntawd, thaum muaj kev tawg tshwm sim hauv cov chaw kho dej phwj tuaj, nws yuav hnyav dua li qhov tawg ntawm ib qho roj.
