Kei roto i tētahi o ngā taiao wai tino uaua ngā whare tukatuka wai para (WWTP): he maha ngā wā ka kī tonu te wai para i ngā totoka, i ngā mirumiru, me ngā taumata matotoru rerekē—ngā āhuatanga ka kore e tika, ka kore hoki e pono ngā mita rere tuku iho (pēnei i ngā tauira ultrasonic miihini, tae atu ki ngā tauira ultrasonic wā-haere paerewa). Koinei te wāhi e tū motuhake ai ngā mita rere ultrasonic Doppler: i hangaia kia tupu pai i roto i ngā wai pōrearea, kī tonu i ngā matūriki, kua noho hei taputapu nui mō te whakarei ake i te aroturukitanga rere i roto i ngā WWTP, te whakarite i te whai huatanga o te mahi, te tutuki i ngā ture, me te whai huatanga utu.
He aha i kore ai e taea e ngā mita rere tuku iho te mahi i roto i ngā pūnaha waiariki
He uaua ki ngā hangarau ine rere tuku iho ngā āhuatanga ahurei o te wai para. Ko ngā mita miihini, e whakawhirinaki ana ki ngā wāhanga neke (hei tauira, ngā tāpoi), ka tere te kapi i ngā paru pērā i te makawe, te hinu, te paru rānei—ka hua ake he tiaki auau, he iti iho te tika, me te wā kore mahi i whakaritea. Ahakoa he whai hua ngā mita ultrasonic wā-haere mō ngā wai ma, he uaua ake ina he nui ngā totoka, ngā mirumiru rānei kei roto i te wai para: ka marara ēnei matūriki i ngā ngaru oro, ka whakararuraru i te kaha o te mita ki te tatau i te tere rere. Mō ngā WWTP, he mea nui ngā raraunga rere tika mō ngā tukanga pērā i te hauhautanga, te ine matū, me te whakahaere paru, ka taea e ēnei herenga te arahi ki te koretake o te mahi, te kore tutuki i ngā ture taiao, me ngā utu koretake.
Me pēhea te whakaoti a ngā mita rere orooro Doppler i ngā wero o te WWTP
He rerekē te kaupapa o ngā mita rere ultrasonic Doppler i ērā atu o ngā mita rere wā-haere—he mea tino pai mō te wai para. Engari ko te ine i te wā e haere ai ngā ngaru oro ki runga, ki raro hoki, ka tukuna e ngā mita Doppler ngā ngaru oro auau-teitei (te nuinga o te wā 0.5–5 MHz) ki roto i te wai. Ka peke atu ēnei ngaru i ngā totoka i whakatārewatia, i ngā mirumiru, i ētahi atu matūriki rānei i roto i te wai para; ka hoki ngā ngaru whakaata ki te pūoko o te mita me te auau kua nekehia (te pānga Doppler). Mā te tātari i tēnei nekehanga auau, ka tatau te mita i te tere o ngā matūriki—ā, nō reira, te tere rere o te wai para.
E toru ngā painga matua o tēnei hoahoa mō ngā WWTP:
- Mahi Ātete-Pūngaru: Nā te korenga o ngā wāhanga neke, ngā wāhanga pokanoa rānei, ka karohia e ngā mita Doppler ngā take pūngaru e pāngia ana e ngā tauira mīhini. Ka taea te tāuta ki waho (te whakapiri ki te paipa) me te iti noa rānei o ngā wāhanga o roto, ka whakaitihia te pa atu ki ngā paru.
- Te Tika o ngā Wai Pōuriuri: Kāore i rite ki ngā mita wā-haere, ka whakawhirinaki ngā tauira Doppler ki ngā matūriki iri kia mahi ai—he tino tika hoki ahakoa i roto i ngā wai para he nui te pōuriuri (hei tauira, te para maimoatanga tuatahi, te paru rānei).
- He iti te tiaki: Nā te korenga o ngā wāhanga miihini hei pakaru, hei horoi rānei, he iti ake te tiaki e hiahiatia ana e ngā mita Doppler i ērā o ngā kōwhiringa tuku iho. Ka whakaitihia te wā kore mahi, ā, ka whakaitihia hoki ngā utu tiaki mō te wā roa mō ngā WWTP.
Ngā Painga Whaihua mō ngā Mahi WWTP
Mō ngā WWTP, ko ngā painga o ngā mita rere ultrasonic Doppler ka puta he whakapainga tūturu i roto i ngā mahi o ia rā:
- Te Whakahaere Tika o te Tukanga: I te wā e whakapūhau ana (he taahiraa matua i roto i te maimoatanga waipara koiora), mā ngā raraunga rere tika ka tika te nui o te hau e tukuna ana ki ngā moroiti—ka arotau i te whai huatanga o te maimoatanga me te whakaiti i te para pūngao. Waihoki, ka āwhina ngā mita Doppler ki te whakahaere i te inenga matū mā te whakarato i ngā tere rere wā-tūturu, me te whakarite kia tāpirihia ngā matū (hei tauira, ngā matū whakapūmau) ki ngā ōwehenga tika hei karo i te whakamahinga nui rawa, te whakamahinga iti rānei.
- Te Whakatutukitanga i ngā Ture: Me aro turuki, me ripoata hoki e ngā tari taiao ngā WWTP i te rerenga mai, te rerenga atu, me te nui o ngā wai para. Ka whakaratohia e ngā mita Doppler ngā raraunga pono, ka taea te arotake e tutuki ana i ēnei paerewa ture, ka whakaiti i te mōrearea o ngā whiu, o te kore rānei e tutuki i ngā ture.
- Te Kitenga i te Tūtaki me te Ārai: Mā te aroturukitanga rere ā-wā tonu ka taea e ngā kaiwhakahaere te kite i ngā āhuatanga rerekē—pērā i te hekenga ohorere o te rere (e tohu ana i te aukati) me te pikinga ohorere (e tohu ana i te turuturu). Mā tēnei ka taea te wawao tere, te ārai i ngā whakararuraru tukanga me te whakaiti i te ngaronga wai.
Whakamutunga
I roto i te taiao uaua o ngā tipu maimoatanga waipara, ka aro atu ngā mita rere ultrasonic Doppler ki ngā herenga nui o ngā hangarau ine rere tuku iho. Nā tō rātou kaha ki te mahi tika i roto i ngā wai paru, kī tonu i ngā matūriki, me te iti o ngā hiahia tiaki me te mahi pono, ka waiho hei taputapu tino nui mō te whakarei ake i te aroturukitanga rere. Mā te whakarite i te whakahaere tukanga tika, te tutuki i ngā ture, me te kimi take matatau, ka āwhina ngā mita rere ultrasonic Doppler i ngā WWTP ki te mahi pai ake, pumau, me te whai hua - hei tautoko i tā rātou kaupapa ki te tiaki i te hauora tūmatanui me te taiao.
