Nitrobenzene Wastewater Cov yam ntxwv zoo
Nitrobenzene tebchaw (xws li nitroaniline, nitrobenzene, nitrochlorobenzene thiab polynitroaromatic hydrocarbons, thiab lwm yam) yog ib qho tseem ceeb ntawm cov khoom siv raw khoom. Lawv tau siv dav hauv kev tsim khoom xws li dyes, tshuaj, tshuaj, tshuaj lom neeg, tshuaj tua kab thiab cov organic synthesis, thiab yog qhov zoo tshaj plaws hauv kev lag luam tshuaj. Yog li ntawd, ntau cov tshuaj nitrobenzene tau nkag mus rau tib neeg lub neej. Lawv muaj cov qauv ruaj khov, tsis yooj yim rau decompose thiab hloov pauv, muaj ntau thiab nyuaj, thiab muaj tshuaj lom rau cov kab mob. Feem ntau, cov tebchaw no yog cov tshuaj lom neeg thiab cov tshuaj carcinogenic, thiab lawv cov tshuaj toxicity feem ntau yog 20 mus rau 30 npaug ntawm lwm cov tebchaw.
Due to their many varieties and varying production sizes, so far, most production processes are relatively backward, the yield is not high, the side reactions are complex, and especially the production wastewater discharged seriously pollutes the environment. Kev tshem tawm ncaj qha ntawm Nitrobenzene Wastewater yuav ua rau muaj cov sib xyaw ua ke los ua kom dav hauv dej thiab av ua kom muaj cov teeb meem purution. Yog li ntawd, lub xeev muaj cov qauv tswj nruj rau kev nkag siab ntawm Nitrobenzene teb chaws yog tias cov kev tso tawm ntau tshaj plaws yog: 2}}}}} Kuv rau qib thib ob, thiab 3. {{0 mg / u rau qib thib peb.
Raws li kev txheeb cais, kwv yees li 30,{1}} tons ntawm nitrobenzene tebchaw raug tso tawm rau hauv ib puag ncig txhua xyoo thoob ntiaj teb. Ntxiv mus, nrog rau kev txhim kho txuas ntxiv ntawm kev lag luam tshuaj niaj hnub no, qhov kev thov rau cov khoom sib txuas no tau qhia meej txog kev nce qib, ntawm cov kev thov thoob ntiaj teb rau nitrobenzene tau loj hlob ntawm tus nqi txhua xyoo ntawm 3.1%. Cov hom thiab ntau npaum li cas ntawm cov tebchaw no nkag mus rau ib puag ncig los ntawm ntau txoj hauv kev kuj tseem yuav nce ntxiv, thiab cov pa phem rau ib puag ncig yuav ua rau muaj mob hnyav ntxiv, ua rau tib neeg kev noj qab haus huv.
Nitrobenzene yog lub teeb daj, tshuaj lom, pob tshab oily kua nrog iab almond tsw. Nws cov mis molecular yog C6H5NO2, nws qhov ceev yog 1.2 g / cm3, nws qhov kub yog 210.8 degree, nws melting point yog -5.7 degree, nws yog ib qho nyuaj rau yaj nyob rau hauv dej, tab sis nws yog yooj yim soluble nyob rau hauv feem ntau cov organic. Cov kuab tshuaj xws li benzene, ether, thiab ethanol. Nyob rau hauv qhov kub thiab txias txias, combustion thiab tawg yuav tshwm sim, thiab nws muaj peev xwm hnov mob heev nrog HNO3. Cov pab pawg nitro hauv nitrobenzene muaj peev xwm nqus tau electrons, uas txo cov huab cua electron ceev ntawm lub nplhaib benzene, ua rau nitrobenzene tsis tshua muaj zog.
Cov yam ntxwv ntawm Nitrobenzene Wastewaterater
Nitrobenzene tebchaw (nitrophenol, nitrobenzene, nitrobenzene, nitrobenzene cydroromatic hydrocarbons hauv cov txheej txheem tshuaj lom neeg. Lawv siv dav siv tshuaj lom neeg, textiles, luam ntawv thiab dyeing kev lag luam.
Cov yam ntxwv ntawm nitrobenzene cov dej khib nyiab yog: nitrobenzene yog insoluble hauv dej thiab muaj qhov ntom ntom dua li dej. Tom qab nkag mus rau hauv lub cev dej, nws yuav nkag mus rau hauv qab dej thiab nyob twj ywm tsis hloov mus rau lub sijhawm ntev, yog li cov dej paug tshwm sim yuav kav ntev heev; Feem ntau cov dej khib nyiab nitrobenzene tawm tsis tu ncua, thiab cov concentration ntawm nitrobenzene tawm los ntawm cov txheej txheem ntau lawm kuj txawv.
Nyob rau tib lub sijhawm, tus nqi ntawm cov dej khib tseem yuav txawv nyob ntawm cov ntsuas ntawm kev tsim khoom ntawm ntau lawm, xws li los ntawm ob peb txhiab tons; Nyob rau hauv cov txheej txheem ntau lawm ntawm nitrobenzene, vim hais tias yog kev hloov pauv hauv kev ua haujlwm xws li kev noj haus xws li pub thiab nkag mus kho Nitrobenzene Wastewater nyuaj; Hauv cov txheej txheem ntau lawm ntawm nitrobenzene thiab aniline, muaj ntau ntawm HCL, H2SO4, NAOH thiab hlau catalysts xws li CU, AL thiab cov organic ntxiv yuav tsum tau ntxiv.
Vim tias cov tshuaj tiv thaiv tsis tiav thiab cov khoom lag luam nqa khoom, nitrobenzene dej khib nyiab muaj cov hlau hnyav thiab qee cov nyom cov organic. Nyob rau tib lub sijhawm, vim yog qhov sib txawv ntawm cov kua qaub thiab alkali, lub ph ntawm Wastewater hloov tsis xwm yeem nyob rau hauv ntau ntau, ua rau kev kho mob ntawm kev nyuaj nyuaj.
TNT thiab DNT dej khib nyiab zoo
TNT yog cov khoom tawg siab, cov hmoov daj los yog flaky, nyuaj rau yaj hauv dej, thiab tuaj yeem siv rau hauv qab dej blasting. Vim nws lub hwj chim loj, nws feem ntau yog siv los ua lub tshuab hluav taws xob thib ob. TNT yog tau los ntawm nitration thiab refining ntawm toluene nrog nitric acid thiab sulfuric acid. Tom qab nitration ntawm toluene, ntau cov kua qaub thiab cov kua qaub (tseem hu ua dej daj) raug tso tawm, thiab cov dej khib nyiab alkaline (tseem hu ua dej liab) yog tsim tom qab ua kom zoo.
Cov yam ntxwv ntawm TNT dej khib nyiab yog: cov tshuaj sib xyaw ua ke, thiab cov tshuaj muaj feem ntau yog qhov muaj teeb meem zoo uas muaj teeb meem zoo; Cov pa paug feem ntau yog mob toxic, uas tuaj yeem ua rau tib neeg lom neeg thiab cov tsiaj txhu lub cev, thiab tsis yooj yim muaj qhov nyuaj los ntawm cov kab mob ntawm cov kab mob dav dav.
DNT yog qhov tseem ceeb hauv nruab nrab rau ntau cov khoom siv tshuaj lom neeg thiab ib qho tsim nyog nruab nrab rau kev tsim cov tnting. Dnt dej so dej yog alkaline organic dej tsim tawm thaum lub sijhawm npaj thiab ua kom zoo thiab ntxuav ntawm DNT. Cov yam ntxwv ntawm DNT dej khib nyiab yog: tsis tshua muaj sib xyaw ua ke muaj nyob hauv cov dej ntas ruaj khov, thiab yog qhov yooj yim los tsim lwm cov txheej txheem lom neeg ntau dua thaum cov txheej txheem kev ua haujlwm.
Txheej Txheem Kho Kom Zoo
Raws li txoj cai, cov cuab yeej siv tam sim no rau kev kho cov dej khib nyiab nitrobenzene tuaj yeem muab faib ua cov txheej txheem sib cais thiab kev hloov pauv.
Kev sib cais txheej txheem yog cais cov kuab paug los ntawm kev sib txig los ntawm lub ntiajteb txawj nqus, thiab lwm yam, cov tshuaj ntawm cov pa phem tsis hloov pauv thaum lub sijhawm sib cais; Feem ntau siv cov txheej txheem sib cais muaj xws li kev tshaj tawm, hle, kev sib cais thiab nag ntsis, sib cais thiab cov kab mob distillation;
Cov txheej txheem hloov dua siab tshiab yog hloov cov kuab lom los ntawm cov tshuaj lom neeg lossis cov tshuaj thiab cov tshuaj lom lossis txo lawv cov tshuaj lom kom tau raws cov qauv emission. Cov txheej txheem kev hloov dua siab tshiab muaj xws li: micro-lub cev muaj zog, phua xov tooj oxidation, phaton oxidation, trochemical catalytic oxidation, thiab lwm yam.
