Txhawm rau tiv thaiv kev sib ntaus sib tua ntawm kev tiv thaiv ozone thiab tswj lub caij ntuj sov no thiab tiv thaiv qhov tshwm sim ntawm cov pa phem hauv ozone, Zhenhai ceg ntawm Ningbo Municipal Ecological Environment Bureau tau nquag txhawb nqa qhov tsis ncaj ncees lawm ncov emission txo hauv kev lag luam petrochemical txij thaum Lub Xya Hli. Los ntawm kev teeb tsa 37 qhov tseem ceeb ozone precursor emission lag luam kom txo qis cov khoom siv siab tshaj plaws los ntawm 10 feem pua, nws xav tias yuav txo qis emissions los ntawm ntau tshaj VOCs50 tons thiab nitrogen oxide ntau dua 70 tons txij Lub Xya Hli mus txog Kaum Ib Hlis.
Ntau qhov kev siv zog los txhawb qhov kev siv. Zhenhai District Ecological Environment Sub-bureau, ua ke nrog cov nroog, txoj kev thiab cov chaw ua si, hais kom cov tuam txhab tsim "ib lub lag luam, ib txoj cai" tawm ntawm kev txo qis qis qis, thiab tawm tswv yim tsim nyog cov lag luam hauv kev lag luam tseem ceeb xws li petrochemical thiab industrial painting industries. los siv tsis ncaj ncees lawm-lub sij hawm thiab off-peak ntau lawm. Hmo ntuj tsim rau VOCs emission txheej txheem, zam lub sij hawm ncov ntawm kub kub ozone paug los ntawm 10 mus rau 19 teev; ntxiv dag zog rau kev kaw cov roj khib nyiab hauv VOCs cov ntaub ntawv khaws cia, kev thauj mus los, siv thiab pov tseg kom ntseeg tau tias txhua qhov tau txais. Tub ceev xwm cov neeg ua haujlwm raug xa mus los pab thiab coj cov kev tsim tawm ntawm kev lag luam. Txij li thaum Lub Xya Hli, 652 qhov kev taw qhia ntawm qhov chaw thiab 318 lub tuam txhab tau raug daws, daws cov teeb meem tseem ceeb thiab nyuaj, xws li kev kho dua tshiab ntawm cov chaw ua haujlwm tsis zoo thiab kev txheeb xyuas thiab kev tswj xyuas cov emissions unorganized. Peb yuav tsom mus rau thaj chaw tseem ceeb thiab ua tiav cov txiaj ntsig zoo. Tsom ntsoov rau cov lag luam loj petrochemical xws li Zhenhai Refining thiab Tshuaj, Zhongjin Chemical thiab Zhenli Chemical, cov thawj coj tseem ceeb ntawm Lub Nroog Ecological ib puag ncig Sub-bureau coj pab pawg tshaj tawm txoj cai tiv thaiv ozone thiab tswj txoj cai, txuas cov peev txheej ntawm kev tsim tawm, thiab txo qhov emission ntawm ozone precursors. Zhenhai Refining thiab Chemical Company thiab nws cov tswv cuab ntawm Zhenhai lub hauv paus, nrog rau cov lag luam tseem ceeb xws li CICC Petrochemical Company thiab Zhenhai Port Chaw Lag Luam, tau tsim cov ncauj lus kom ntxaws txog kev txo qis qis qis, nrog rau cov kev ntsuas tseem ceeb suav nrog txo cov khoom tsim tawm thiab txo kev thauj khoom thiab unloading thaum lub sij hawm kub kub thaum tav su. Ntawm 56 qhov tseem ceeb atmospheric emission units, 37 tau tshaj tawm cov phiaj xwm tsim tawm, suav txog 66 feem pua.
Cov ntaub ntawv tsom xam thiab lav qhov txo tus nqi. Lub VOCs navigation soj ntsuam lub tsheb tshuaj xyuas yog siv los ua qhov kev soj ntsuam tag nrho ntawm lub voj voog ntawm kev txo qis qis qis ntawm cov lag luam tseem ceeb txhua hnub. Siv 55 pawg ntawm VOCs Hoobkas ciam teb kev soj ntsuam hauv online thiab 149 cov txheej txheem kev soj ntsuam tas li, kev saib xyuas lub sijhawm tiag tiag thiab kev tshuaj xyuas ntawm VOCs emission teeb meem ntawm cov tuam txhab tseem ceeb yog ua kom muaj kev ruaj ntseg ntawm VOCs emission cov ntaub ntawv thiab ib puag ncig saib xyuas cov ntaub ntawv thaum lub sij hawm. qhov kub thiab txias. Ua cov kev tshawb fawb tshwj xeeb ntawm ozone pollution, integrate meteorological, ib puag ncig, ntau lawm thiab nyob yam tseem ceeb, ua nyob rau hauv-tob soj ntsuam ntawm ozone soj ntsuam cov ntaub ntawv, muaj pes tsawg leeg cov ntaub ntawv thiab tiam cov cai ntawm lub regional automatic atmospheric soj ntsuam chaw nres tsheb, sau cov petrochemical kev lag luam, roj tswj thiab Lwm cov kev lag luam ua qhov tseem ceeb ntawm kev tswj hwm ozone, thiab tsim cov phiaj xwm tswj kev kub ntxhov.
