Dej yog lub hauv paus rau kev ciaj sia ntawm lub ntiaj teb biology. Cov peev txheej dej yog cov xwm txheej tseem ceeb rau kev tswj kom muaj kev loj hlob ntawm lub ntiaj teb ecological ib puag ncig. Yog li ntawd, kev tiv thaiv dej yog lub luag haujlwm tseem ceeb tshaj plaws thiab dawb ceev tshaj plaws ntawm tib neeg. Niaj hnub no, muaj ntau qhov chaw dej paug, thiab muaj cov dej tshiab tsawg thiab tsawg. Ntau lub tuam txhab tau pib siv kev ntsuas dej. Hnub no, kuv yuav qhia rau koj paub meej.
1. Kev sib haum xeeb ntawm tib neeg lub cev thiab lub hlwb kev noj qab haus huv: Tom qab dej muaj kuab paug, raws li cov dej haus lossis cov khoom noj khoom haus, cov pa phem nkag mus rau hauv lub cev, ua rau tib neeg mob hnyav lossis lom. Arsenic, chromium, ammonium, benzene (A), thiab lwm yam, tuaj yeem ua rau mob qog noj ntshav. Cov dej uas kis tau los ntawm ib puag ncig cov pa phem ntawm cov kab mob los yog lwm yam kab mob pathogenic tuaj yeem ua rau muaj ntau yam kab mob thiab kab mob parasitic.
2. Kev puas tsuaj rau kev tsim khoom lag luam: Tom qab cov dej hauv lub cev ib puag ncig muaj kuab paug, cov nyiaj yuav tsum tau muab tso rau hauv kev lag luam dej phwj kho kom daws tau cov nqi, ua rau khoom kim heev thiab pov tseg ntawm cov peev txheej, lub zog thiab lub zog. Kev tsim khoom nres.
3. Kev puas tsuaj rau cov khoom noj khoom haus nplua nuj: Raws li ib txwm muaj, oxygen yog soluble hauv dej. Cov pa oxygen tsis yog tsuas yog tus qauv rau kev ciaj sia ntawm cov kab mob hauv dej, tab sis kuj yog cov pa oxygen rau kev koom tes hauv ntau yam huab cua oxidation-xov xwm hauv dej thiab txhawb kev hloov pauv ntawm cov pa phem. Nws yog tus yuam sij rau cov dej ntshiab huv.
Nrog rau txoj kev loj hlob ntawm kev loj hlob ntawm kev sib raug zoo, qhov teeb meem ntawm ib puag ncig muaj kuab paug tau dhau los ua qhov tseem ceeb. Thiab txij li thaum ua raws li ISO14000 series ntawm cov khoom specifications, lub teb chaws nyob ib ncig ntawm lub ntiaj teb no tau khawb tam sim ntawd tus qauv ntawm kev soj ntsuam thiab xyuas, thiab kev paub txog ntawm kev tiv thaiv cov khoom siv dej tau nce zuj zus.
1. Kev kuaj xyuas dej khib nyiab:COD, BOD, ammonia, tag nrho phosphorus, tag nrho nitrogen, fluoride, sulfides, hnyav ions, anion deg active agents, thiab lwm yam.
Kev Tsim Khoom Siv Khoom Siv Hluav Taws Xob (Lus Askiv: Industral Wastewater) muaj cov dej khib nyiab tsim khoom thiab cov dej khib nyiab ntau lawm, uas yog hais txog cov dej khib nyiab thiab cov dej khib nyiab los ntawm tag nrho cov txheej txheem ntawm kev tsim khoom. Nyob rau hauv nws Pollutants tshwm sim nyob rau hauv cov txheej txheem ntau lawm. Cov dej tau tawm hauv cov txheej txheem tsim khoom.
Raws li lub cev cov khoom ntawm cov pa phem tseem ceeb hauv cov dej khib nyiab hauv kev lag luam, nws tau muab faib ua: cov dej khib nyiab inorganic tswj hwm los ntawm cov pa phem tsis zoo, cov dej khib nyiab organic ua los ntawm cov pa phem, cov dej khib nyiab sib xyaw, cov hlau hnyav uas muaj cov organic tebchaw thiab cov tshuaj inorganic, thiab cov khib nyiab inorganic. dej tshaj cov dej txheem, cov dej khib nyiab uas muaj cov khoom siv hluav taws xob, thiab cov dej txias uas muaj cov dej paug los ntawm qhov chaw sov. Piv txwv li, cov dej khib nyiab ntawm cov txheej txheem electroplating cov dej khib nyiab thiab cov txheej txheem tsim cov ntxhia yog cov dej khib nyiab inorganic, thiab cov dej khib nyiab ntawm cov khoom noj lossis cov txheej txheem roj yog cov organic chemical wastewater.
Raws li cov chaw tsim khoom lag luam 'cov khoom lag luam thiab kev tsim khoom thiab kev ua cov hom phiaj, lawv tuaj yeem muab faib ua cov ntawv ua cov dej khib nyiab, cov khoom siv khib nyiab, cov dej khib nyiab, cov dej khib nyiab, cov dej khib nyiab metallurgical, thiab cov roj refining pov tseg.
Cov khoom xyaw tseem ceeb ntawm cov pa phem hauv cov dej khib nyiab tuaj yeem muab faib ua pH cov dej khib nyiab, cov dej khib nyiab alkaline, phenol-muaj cov dej khib nyiab, chromium-muaj cov dej khib nyiab, cov dej khib nyiab organic phosphorus, thiab cov khoom siv hluav taws xob.
Tsuas yog cov dej khib nyiab nyob rau hauv tus txheej txheem ntau tom qab kev kho cov dej khib nyiab thiab tshawb pom tuaj yeem tso tawm mus rau qhov chaw teev tseg. Nws yog txwv tsis pub tso tawm ntau tshaj tus qauv thiab txwv tsis pub muaj kev tso tawm tsis raug cai.
Thib ob, kev tshawb nrhiav cov khaub ncaws, khoom noj, chaw nyob thiab kev thauj mus los cov dej khib nyiab: pH tus nqi, CODCR, NH3-N, TP, SS, roj av, tsiaj txhu thiab cov roj cog, thiab lwm yam.
Thib peb, nrhiav pom dej saum npoo av: tus nqi pH, NH3-N, TP, SS, biochemical oxygen thov, thiab lwm yam.
Lub ntuj ib puag ncig ntawm lub hauv paus dej ntws dej thiab kev saib xyuas ntawm lub hom phiaj tag nrho yog muab faib ua tsib pawg raws li qhov siab ua haujlwm. Tsib hom dej ntawm thaj chaw dej saum npoo av tau muab faib ua tsib pawg ntawm txoj haujlwm tshiab ntawm qhov zoo ntawm cov dej saum npoo av. Hom txhua qhov siv ib hom txheeb ze ntawm qhov ntsuas tus nqi. Qhov taw qhia qhov tseem ceeb nrog cov hom kev ua haujlwm siab yog raug ntaus ntau tshaj qhov ntsuas qhov tseem ceeb nrog cov dej ua haujlwm tsawg. Hauv cov dej tib yam, muaj ntau hom kev ua haujlwm, thiab qhov ntsuas qhov tseem ceeb uas haum rau hom kev ua haujlwm feem ntau yog siv. Kev tuav dej num thiab kev ua haujlwm ntawm cov dej num yog tib lub ntsiab lus.
Plaub, kev tshawb nrhiav dej saum npoo: dej ntshiab thiab kev taw qhia hluav taws xob, cov hlau hnyav tshaj tus qauv zoo ion, thiab lwm yam.
Qhov project tshiab:
Aniline, sab hauv tsev formaldehyde, saturation, suspended solids, pH nqi,tsib hnub biochemical oxygen xav tau (BOD5), permanganate index, CODcr, tag nrho phosphorus, polyphosphate, chloride, tag nrho arsenic, hexavalent chromium, tag nrho chromium, hydrogen cyanide, volatile phenol, tsiaj thiab zaub roj, cationic surfactant, hlau, manganese, npib tsib xee, volatile phenol, kub, yaj, oxygen tag nrho nitrogen, tooj liab, cadmium, zinc, txhuas, thiab lwm yam.
Qhov tseem ceeb ntawm kev kuaj xyuas dej zoo:
Kev nyab xeeb dej nyab xeeb: Kev saib xyuas dej zoo tuaj yeem tshawb pom cov pa phem thiab cov khoom tsis zoo tshwm sim hauv cov dej thiab cov kav dej sib txuas, tiv thaiv cov dej tsis zoo los ntawm kev ua qias tuaj thiab ua kom lub neej thiab kev noj qab haus huv ntawm pej xeem.
Kev soj ntsuam ib puag ncig muaj kuab paug: Cov chaw saib xyuas dej zoo hauv ntau qhov chaw raug sim ntawm ntau hom tshuaj hauv cov dej sib txawv - hom dej hauv dej xws li cov dej ntws thiab cov pas dej, thiab tshaj tawm cov dej muaj kuab paug los ntawm cov dej, kev lag luam, thiab kev ua neej nyob hauv dej. av ua liaj ua teb, kev lag luam, thiab lub neej nyob rau hauv lub sij hawm.
Kev hloov pauv huab cua: Los ntawm kev saib xyuas dej zoo, koj tuaj yeem nkag siab txog kev tu cev tam sim no, ib puag ncig ecological thiab cov khoom muaj kuab paug ntawm cov dej hauv dej, thiab tom qab ntawd kwv yees qhov sib txawv ntawm cov dej ntws thiab coj kev txhim kho thiab kev siv dej.
Kev ntsuam xyuas thiab kev tswj xyuas cov txiaj ntsig: Kev saib xyuas dej tsis tu ncua tuaj yeem nkag siab txog qhov cuam tshuam ntawm kev tswj hwm kev ua qias tuaj thiab nws cov teebmeem, thiab muab cov neeg ua haujlwm tswj hwm ib puag ncig los kho thiab txhim kho txoj cai tswjfwm thiab kev ntsuas raws sijhawm txhawm rau txhim kho kev tswj hwm.
Hauv ntej, kev saib xyuas dej zoo, ua lub hauv paus rau kev txhim kho thiab siv cov peev txheej dej, ua lub luag haujlwm tseem ceeb ntawm kev tiv thaiv ib puag ncig ecological, kev txhim kho thiab kev siv, thiab kev ua neej zoo ntawm pej xeem.
