Tauira Whakamahinga o tētahi Whare Hiko Wera i Shanghai

Kei roto i te whānuitanga pakihi a Shanghai Certain Thermal Power Co., Ltd. e kapi ana i te whakaputa me te hoko i te pūngao wera, te whakawhanake i ngā hangarau whakaputa hiko wera, me te whakamahinga whānui o te pungarehu rere. I tēnei wā, e toru ngā kohua hau māori e whakahaerehia ana e te kamupene, he 130 tāne ia hāora te kaha, me ētahi huinga whakaputa hiko mamaoa pēhanga-muri e toru, he 33 MW te kaha katoa kua tāutahia. E whakarato ana i te mamaoa ma, he pai ki te taiao, he kounga teitei ki te neke atu i te 140 ngā kaiwhakamahi ahumahi kei roto i ngā rohe pēnei i te Jinshan Industrial Zone, Tinglin Industrial Zone, me Caojing Chemical Zone. Neke atu i te 40 kiromita te roa o te whatunga tohatoha wera, e tutuki pai ana i ngā hiahia whakamahana o te Jinshan Industrial Zone me ngā rohe ahumahi e karapoti ana.

Kua whakauruhia te pūnaha wai me te mamaoa i roto i te tipu hiko wera puta noa i ngā tukanga whakaputa maha, ā, he mea nui te aroturuki i te kounga wai hei whakarite i te haumaru me te pono o te mahi a te pūnaha. Ka whai wāhi te aroturuki whai hua ki te mahi pumau o te pūnaha wai me te mamaoa, ka whakarei ake i te whai huatanga o te pūngao, ā, ka whakaiti i te pakaru o ngā taputapu. Hei taputapu nui mō te aroturuki ipurangi, he mahi nui tā te tātari kounga wai i roto i te kohikohi raraunga wā-tūturu. Mā te whakarato urupare wā-tūturu, ka taea e ngā kaiwhakahaere te whakarerekē wawe i ngā tikanga maimoatanga wai, ā, mā reira ka ārai i te kino o ngā taputapu me ngā mōrearea haumaru, me te whakarite i te mahi pai me te pumau o te pūnaha whakaputa hiko.
Te aroturuki i ngā taumata pH: Me pupuri te uara pH o te wai poiha me te wai whakapūkara mamaoa i roto i te awhe kawakore e tika ana (i waenga i te 9 me te 11). Ko ngā rerekētanga mai i tēnei awhe—he waikawa rawa, he kawakore rawa rānei—ka arahi pea ki te waikura o ngā paipa me ngā poiha whakarewa, ki te hanganga unahi rānei, inā koa ka kitea he paru. Hei tāpiri, ko ngā taumata pH rerekē ka whakararu i te parakore o te mamaoa, ka pā ki te whai huatanga me te roa o te mahi o ngā taputapu o raro pērā i ngā tāwhana mamaoa.

Te aroturuki i te kawe hiko: He tohu te kawe hiko mō te parakore o te wai mā te whakaata i te kukū o ngā tote me ngā katote rewa. I roto i ngā tipu hiko wera, me tutuki i te wai e whakamahia ana i roto i ngā pūnaha pēnei i te wai whāngai poiha me te wai whakapūhaumāota ngā paerewa parakore pakari. Ka taea e ngā taumata teitei o te poke te hua ake he tauine, he waikura, he whakaheke i te pai o te wera, me ngā aituā kino pea pēnei i te pakaru o ngā paipa.

Te aroturuki i te hāora rewa: He mea nui te aroturuki tonu i te hāora rewa hei ārai i te waikura e puta mai ana i te hāora. Ka taea e te hāora rewa i roto i te wai te tauhohe matū ki ngā wāhanga whakarewa, tae atu ki ngā paipa me ngā mata whakamahana poiha, ka arahi ki te pirau o ngā rauemi, te angiangi o te pakitara, me te turuturu. Hei whakaiti i tēnei mōrearea, ka whakamahia e ngā tipu hiko wera ngā deaerator, ā, ka whakamahia ngā tātari hāora rewa hei aroturuki i te tukanga deaeration i te wā tonu, kia mau tonu ai ngā taumata hāora rewa i roto i ngā rohe e whakaaetia ana (hei tauira, ≤ 7 μg/L i roto i te wai whāngai poiha).

Ko tēnei rangahau take e aro ana ki te kaupapa whakahou i te whata tauira i tētahi tipu hiko wera i Shanghai. I mua, i whakauruhia te whata tauira ki ngā taputapu me ngā mita mai i tētahi waitohu kawemai; heoi, kāore i pai te mahi i te papaanga, ā, kāore i tutuki i te tautoko i muri i te hoko ngā tumanakohanga. Nō reira, i whakatau te kamupene ki te tūhura i ngā huarahi kē atu o te whare. I whiriwhiria a Botu Instruments hei waitohu whakakapi, ā, i whakahaerehia he aromatawai taipitopito i te papaanga. Ahakoa i whakaurua e te pūnaha taketake ngā irahiko kawemai, ngā kapu rere-mā roto, me ngā pou whakawhiti katote, he mea hanga motuhake katoa ēnei, ko te mahere whakatikatika ehara i te mea ko te whakakapi i ngā taputapu me ngā irahiko anake engari ko te whakapai ake i ngā kapu rere-mā roto me ngā pou whakawhiti katote.

I te tīmatanga, i whakaarohia e te hoahoa he whakarerekētanga iti ki ngā kapu rere-ā-roto me te kore e whakarerekē i te hanganga o te ara wai o nāianei. Heoi, i te wā o tētahi haerenga ki te papa i muri mai, i whakatauhia ka taea e aua whakarerekētanga te whakararu i te tika o te ine. Whai muri i te kōrero tahi me te tīma hangarau, i whakaaetia kia whakatinanahia katoatia te mahere whakatikatika whānui a BOQU Instruments hei whakakore i ngā tūponotanga mōrearea i roto i ngā mahi a meake nei. Nā ngā mahi tahi a BOQU Instruments me te tīma hangarau i te papa, i oti pai te kaupapa whakatikatika, ā, i taea ai e te waitohu BOQU te whakakapi pai i ngā taputapu kawemai i whakamahia i mua.

He rerekē tēnei kaupapa whakatikatika i ngā kaupapa tipu hiko o mua nā te mahi tahi me te kaihanga anga tauira me ngā whakaritenga i mua. Kāore he wero nui e pā ana ki te mahi, ki te tika rānei o ngā taputapu i te wā i whakakapia ai ngā taputapu kawemai. Ko te wero matua ko te whakarerekē i te pūnaha ara wai hiko. Ko te whakatinanatanga angitu i hiahiatia he māramatanga hōhonu ki te kapu rere hiko me te whirihoranga ara wai, me te mahi tahi tata ki te kaiwhakatū miihini, inā koa mō ngā mahi whakarewa paipa. Hei tāpiri, i a mātou he painga whakataetae i roto i te ratonga muri-hoko, nā te mea he maha ngā wā whakangungu i whakaratohia ki ngā kaimahi i te papaanga e pā ana ki te mahi a ngā taputapu me te whakamahinga tika.
