1. Papamuri Kaupapa
Ko Donghai Fisheries Co., Ltd., kei Peru, he umanga whakaputa ika kēne hou, ā, ko te kaha whakaputa ā-tau he 10000 tana. Ko te wai para e puta ana i roto i tana tukanga whakaputa he āhuatanga ahumahi noa iho: ko te tukunga o te wai para i ia rā he tata ki te 800 tana, ko te nui o te hinu he teitei ake i te 350-400mg/L, he nui atu i ngā paerewa tukunga, ā, he nui hoki te pūmua, ngā para unahi ika, me ngā rauemi tukatuka toenga. Ko te kukū COD kei roto i te awhe 2500-3000mg/L mō te wā roa. Ka taea e te tukanga tuku iho "whakaterenga whatunga+hau+matū koiora" te tango i ētahi poke, engari he iti te whai huatanga o te tukanga tātari pehanga, ā, ko te nui o te makuku o te keke tātari he teitei ake i te 75%, e kore e arahi noa ki te pikinga tere o te utu o te maimoatanga paru i muri mai, engari kei te rerekē tonu te nui o te hinu i roto i te wai para i waenga i te 80-120mg/L, e uaua ai te whakatutuki i ngā paerewa pumau.
2. Ngā Wero Matua me ngā Otinga
Ngā uauatanga o te wehenga hinu:
Kei roto i te wai para ika kēne te hinu kua whakaemuhia, kua whakatārewahia hoki, ā, he uaua ki ngā tukanga whakamānu hau tuku iho te wawahi katoa i te whakaemu. Ka whakauruhia e te tīma kaupapa hemīhini tātari rūma waipēhi aunoa e whakahaerehia ana e te hōtaka, me te kakahu tātari polypropylene ātete hinu, hei pupuri i te hinu mā te tātari e toru ngā wāhanga:
Wāhanga i mua i te maimoatanga:Ka tukatukahia te wai para ki te wehewehe hinu hei tango i te hinu e mānu ana, kātahi ka tāpirihia te matū whakapūkara FeClⅢ (inenga o te 400mg/L) hei whakararuraru i te pumau o te koloid, ka hanga he putunga matūriki he rahi matūriki >50 μm;
Wāhanga pēhi tātari:I raro i te pēhanga whāngai o te 0.8 MPa, ka hangaia he paparanga keke tātari hihiri ki runga i te mata o te kakahu tātari, e aukati ana i ngā pata hinu he nui ake te rahi o te matūriki i te 1 μ m. I taua wā anō, ka whakapakari te hanganga pūkohu i runga i te mata o te pereti tātari i te ārai ā-pūkaha o te hinu kua whakaemulsified;
Wāhanga pēhi:Tāpirihia he pēhanga o te 1.2MPa ki te keke tātari mā roto i tētahi pūnaha waipēhi, ka whakaputa atu i te hinu, ā, i te mutunga ka whakaitihia te nui o te makuku o te keke tātari ki raro iho i te 55% me te nui o te hinu ki raro iho i te 8%.
Te whakapai ake i te whai huatanga o te wehenga totoka-wai:
Mā te pūnaha whitiki kawe tango aunoa e tautoko ana (me te whānui o te 800mm me te tere kawe o te 0.5m/s) ka tutuki te aunoatanga katoa o te tukanga tātari pehanga, te tango, me te kawe:
Hononga atamai:Kia oti te huringa mahi kotahi a te mīhini tātari (tata ki te 45 meneti), ka tuwhera aunoa te pereti tātari, ā, ka paheke te keke tātari ki raro ki te whitiki kawe mā te kaha ā-papa;
Hoahoa ārai-piri:Ka pania te mata o te whitiki kawe ki te paninga PTFE, ka honoa ki te taputapu rehu wai pēhanga-teitei, kia kore ai e aukatia te kawe e te piri o te keke tātari;
Te whakamahinga rauemi:Ka taea te whakamahi tika i te keke tātari he 55% te nui o te makuku hei rauemi mata mō te whāngai, ā, e kiia ana ka taea e ia te whakaputa moni whiwhi mai i ngā hua taha tata ki te 120,000 yuan ia tau.
Pēhi tātari momo pouaka:he pūnaha whakahaere PLC tōna, ā, ka taea e ia te whakarite aunoa i te pēhanga whāngai me te wā pēhi kia rite ki te kounga o te wai e tomo mai ana. E whakaatu ana ngā raraunga whakamātautau tūturu ko te whakapaunga hiko mō te maimoatanga i te kotahi tana o te wai para he 0.85 kWh noa iho, he 40% te iti iho i ngā mīhini tātari pereti me te anga tuku iho;
Whitiki kawe:He hononga maeneene ki te tauranga tukunga o te mīhini tātari, e whakamahi ana i te hoahoa modular, ka taea te whakakapi tere i ngā wāhanga kua pakaru, ā, ka roa ake te huringa tiaki ki te 6 marama.
3,Te pānga o te whakatinanatanga me ngā painga ōhangaNgā painga taiao:
Kua heke te nui o te hinu i roto i te para mai i te 120mg/L i mua i te whakahoutanga ki te 12mg/L, me te tere tango COD o te 97% me te hekenga ā-tau o te tata ki te 28 tana o ngā tukunga hinu;
I heke te nui o te makuku o te keke tātari mā te 20%, ā, i heke te nui o te paru i haria ki waho mai i te 60 tana ia marama ki te 22 tana, ā, i whakaitihia ngā utu kawe mā te 70%.
te mahi ōhanga:
Ko te moni whiwhi ā-tau mai i te whakamahinga rauemi o te keke tātari he 120,000 yuan, e whakaiti ana i te 60% o te utu whakahekenga uara o ngā taputapu pēhi tātari;
Kua heke te utu katoa mō te hiko me te rongoā mā te 35%, ā, kua penapenahia he moni ā-tau mō te 250,000 yuan i roto i ngā whakapaunga whakahaere.
ngā hua pāpori:
I muri i te whakatinanatanga o te kaupapa, i paahitia e te hinonga te tiwhikete pūnaha whakahaere taiao ISO 14001, ā, ka noho hei paearu mō te tiaki taiao i roto i te umanga tukatuka hua wai o te rohe, me te whakatairanga i te whakapainga o te taumata hanga matomato ā-rohe.
4. Arotake a te kiritaki
Mā te whakauru i tētahi otinga whakakotahi o te mīhini tātari momo pouaka me te whitiki kawe, kua ea katoa i a mātou te raruraru roa o te maimoatanga wai para. Ināianei, ehara i te mea ka taea e mātou te whakatutuki i te tukunga pumau me te tutuki i ngā whakaritenga anake, engari ka taea hoki te whakamahi i te keke tātari hei rauemi mata hei hanga moni tāpiri. Ko te taumata mohio o tēnei taputapu he nui ake i ngā tumanakohanga, ā, kua tata ki te haurua te hekenga o ngā utu whakahaere me te tiaki.
