Kev lag luam kws tshuaj yog ib feem tseem ceeb ntawm kuv lub teb chaws kev lag luam hauv lub tebchaws, tab sis kev lag luam tshuaj yog ib qho kev lag luam uas muaj kuab paug ntau, thiab nws qhov kev cuam tshuam loj heev rau cov dej ib puag ncig tau dhau los ua qhov teeb meem kub ntawm kev txhawj xeeb thoob ntiaj teb. Kev lag luam kws tshuaj tau teev tseg raws li ib qho ntawm kaum qhov kev lag luam tseem ceeb rau kev kho tshwj xeeb raws li "Ten Water Regulations".
Pharmaceutical kev lag luam khib nyiab yog ib qho ntawm cov refractory industrial wastewaters. Vim muaj ntau hom tshuaj thiab cov txheej txheem ntau lawm, nws muaj cov yam ntxwv ntawm qhov sib txawv loj ntawm cov khoom sib txawv, cov khoom siv tsis yooj yim, cov pa phem ntau, COD siab, ntau cov tshuaj refractory, thiab muaj zog toxicity.
Thaum Lub Rau Hli 25, 2008, Ministry of Ecology thiab Ib puag ncig thiab Kev Tswj Xyuas Kev Tswj Xyuas Zoo, Kev Tshuaj Xyuas thiab Quarantine ntawm Cov Neeg Sawv Cev ntawm Tuam Tshoj tau tshaj tawm cov qauv rau kev tso dej paug tawm hauv kev lag luam tshuaj. Kev npaj sib xyaw.
Cov dej khib nyiab pov tseg los ntawm cov tuam txhab muag tshuaj yog tsom rau kev tiv thaiv kev ua qias tuaj thiab tswj. EIA yuav txiav txim siab txog cov txheej txheem kho dej khib nyiab tsim nyog raws li kev lag luam cov txheej txheem tsim khoom, hom dej khib nyiab, dej khib nyiab zoo thiab ntau, thiab lwm yam.
Cov yam ntxwv ntawm cov dej khib nyiab
1. Kev thauj khoom siab: COD ntawm cov tshuaj khib nyiab feem ntau yog los ntawm cov tshuaj reactants, cov kuab tshuaj, cov khoom thiab cov khoom siv los ntawm cov khoom siv. Tus nqi COD feem ntau yog nyob rau hauv thaj tsam ntawm kaum tawm txhiab mus rau pua pua txhiab, thiab qhov B / C piv yog tsawg dua 0.1. Cov cuab yeej biochemical tsis zoo, thiab nws nyuaj rau ua raws li kev kho mob biochemical.
2. High toxicity: Cov pa phem ntawm cov dej khib nyiab muaj xws li tshuaj tua kab mob, DMF, THF, acetone, chloroform, thiab benzene, uas inhibit qhov kev ua ntawm cov kab mob.
3. High salinity: the source of wastewater is raw material, by-products of a synthesis reaction, etc. Cl-, SO42- content>20000 ppm; belongs rau tov ntsev. High salinity yuav dehydrate thiab inactivate los yog txawm tuag ntawm microbial hlwb; tshaj qhov txwv ntawm kev kho mob biochemical; nce qhov ceev ntawm cov dej khib nyiab thiab ua kom cov sludge ntab; corrode khoom
4. Kev nyuaj: Vim qhov tshwj xeeb ntawm kev lag luam tshuaj, cov khoom sib txawv ntawm cov khoom yuav ua rau muaj kev hloov loj hauv cov dej tsis zoo ntawm cov dej khib nyiab.
tubular hom thiab spherical hom. Hom kheej kheej yog welded los ntawm ntxeem tau titanium kheej kheej nto thiab titanium phaj. Nws tuaj yeem txuas ncaj qha rau cov yeeb nkab xov. Ntau yam kev sib txuas kev sib txuas tuaj yeem raug kho raws li cov kev xav tau tshwj xeeb ntawm cov neeg siv khoom.
Nws yog dav siv hauv cov dej haus. Ozone sterilization thiab reclaimed dej rov qab siv, dej phwj kho aeration tank aeration, fermentation oxygenation, thiab lwm yam.
