Kutsatira malamulo okhudza kuyenda kwa madzi otayira ku Fowey

Pano ku magazini ya Water, nthawi zonse timafunafuna mapulojekiti omwe apambana mavuto m'njira zomwe zingapindulitse ena. Poyang'ana kwambiri pa kuyeza kayendedwe ka madzi ku malo ang'onoang'ono oyeretsera madzi a zinyalala (WwTW) ku Cornwall, tinalankhula ndi omwe adatenga nawo mbali mu projekitiyi…
Ntchito zazing'ono zoyeretsera madzi zinyalala nthawi zambiri zimakhala ndi zovuta zazikulu kwa mainjiniya oyeretsera ndi owongolera. Komabe, malo oyezera madzi ogwirizana ndi malamulo akhazikitsidwa pafakitale ku Fowey, kum'mwera chakumadzulo kwa England, ndi mgwirizano wokhudza kampani yamadzi, kontrakitala, wopereka zida ndi kampani yowunikira.

Chowunikira kayendedwe ka madzi ku Fowey WwTW chinafunika kusinthidwa ngati gawo la pulogalamu yokonza zinthu zomwe zinali zovuta chifukwa cha kufooka kwa malowo. Chifukwa chake, mayankho atsopano adawonedwa ngati njira ina m'malo mwa njira yosinthira yofanana ndi yomwe inachitika.

Mainjiniya ochokera ku Tecker, kontrakitala wa MEICA ku South West Water, adawunikanso njira zomwe zilipo. "Njirayo ili pakati pa ngalande ziwiri zolowera mpweya, ndipo panalibe malo okwanira oti awonjezere kapena kupotoza njirayo," akutero Ben Finney, injiniya wa polojekiti ya Tecker.

Kuyeza molondola kayendedwe ka madzi otayira kumathandiza oyang'anira malo oyeretsera madzi kuti agwire bwino ntchito - kukonza bwino njira yoyeretsera madzi, kuchepetsa ndalama komanso kuteteza chilengedwe. Chifukwa cha zimenezi, bungwe la Environment Agency lakhazikitsa zofunikira zogwirira ntchito pa zipangizo zoyeretsera madzi ndi nyumba za malo oyeretsera madzi otayira ku England. Muyezo wa magwiridwe antchito umafotokoza zofunikira zochepa zodziyeretsera madzi otayira.

Muyezo wa MCERTS umagwira ntchito ku malo omwe ali ndi zilolezo motsatira Malamulo a Zilolezo Zachilengedwe (EPR), omwe amafuna kuti ogwira ntchito zokonza zinthu aziyang'anira kuyenda kwa madzi m'madzi a zimbudzi kapena madzi otayira amalonda ndikusonkhanitsa ndikulemba zotsatira zake. MCERTS imakhazikitsa zofunikira zochepa zodziyang'anira okha kuyenda kwa madzi, ndipo ogwira ntchitowo adayika mita zomwe zimakwaniritsa zofunikira za zilolezo za Environmental Agency. Chilolezo cha Wales Natural Resources chingaperekenso kuti njira yowunikira kuyenda kwa madzi yavomerezedwa ndi MCERTS.

Machitidwe ndi mapangidwe oyezera kayendedwe ka madzi nthawi zambiri amawunikidwa chaka chilichonse, ndipo kusatsatira malamulo kungayambitsidwe ndi zinthu zingapo, monga kukalamba ndi kuwonongeka kwa njira, kapena kulephera kupereka kulondola kofunikira chifukwa cha kusintha kwa kayendedwe ka madzi. Mwachitsanzo, kukula kwa anthu am'deralo limodzi ndi kuchuluka kwa mvula chifukwa cha kusintha kwa nyengo kungayambitse "kusefukira" kwa nyumba zoyendera madzi.

Kuyang'anira kayendedwe ka madzi m'fakitale yotsukira zinyalala ya Fowey

Potsatira pempho la Tecker, mainjiniya adapita kumalowa ndipo m'zaka zaposachedwa kutchuka kwa ukadaulo kwawonjezeka kwambiri. ""Izi nthawi zambiri zimachitika chifukwa chakuti ma flowmeter amatha kuyikidwa mwachangu komanso mosavuta panjira zowonongeka kapena zokalamba popanda kufunikira ntchito zazikulu."

"Ma flowmeter olumikizidwa adaperekedwa mkati mwa mwezi umodzi kuchokera pamene adayitanitsa ndipo adayikidwa pasanathe sabata imodzi. Mosiyana ndi zimenezi, ntchito yokonza kapena kusintha masinki imatenga nthawi yayitali kukonzekera ndikugwiritsa ntchito; Zimawononga ndalama zambiri; Kugwira ntchito kwabwinobwino kwa fakitale kudzakhudzidwa ndipo kutsatira malamulo a MCERTS sikungatsimikizidwe."

Njira yapadera yolumikizirana ndi ma ultrasound yomwe imatha kuyeza liwiro la munthu payekha pamlingo wosiyanasiyana mkati mwa gawo la kayendedwe ka madzi. Njira iyi yoyezera kayendedwe ka madzi m'chigawo imapereka mbiri ya kayendedwe ka madzi ya 3D yowerengedwa nthawi yeniyeni kuti ipereke kuwerenga kayendedwe ka madzi mobwerezabwereza komanso kotsimikizika.

Njira yoyezera liwiro imachokera pa mfundo ya kuwunikira kwa ultrasound. Kuwunikira m'madzi otayira, monga tinthu tating'onoting'ono, mchere kapena thovu la mpweya, kumayesedwa pogwiritsa ntchito ma pulse a ultrasound okhala ndi Angle inayake. Echo yomwe imachokera imasungidwa ngati chithunzi, kapena echo pattern, ndipo scan yachiwiri imapangidwa patatha ma millisecond angapo. Pattern yomwe imachokera imasungidwa ndipo pogwirizanitsa/kuyerekeza zizindikiro zomwe zasungidwa, malo a reflector yodziwika bwino amatha kuzindikirika. Chifukwa ma reflector amayenda ndi madzi, amatha kuzindikirika m'malo osiyanasiyana pachithunzichi.

Pogwiritsa ntchito ngodya ya beam Angle, liwiro la tinthu tating'onoting'ono limatha kuwerengedwa ndipo motero liwiro la madzi otayira limatha kuwerengedwa kuchokera ku nthawi yomwe chowunikiracho chimasuntha. Ukadaulowu umapanga mawerengedwe olondola kwambiri popanda kufunikira koyesa zina zowonjezera.

Ukadaulowu wapangidwa kuti ugwire ntchito mu chitoliro kapena chitoliro, zomwe zimathandiza kuti ntchito ikhale yogwira mtima kwambiri pa ntchito zovuta komanso zoipitsa. Zinthu zomwe zimakhudza monga mawonekedwe a sinki, makhalidwe a madzi ndi kuuma kwa khoma zimaganiziridwa powerengera madzi.

Izi ndi zinthu zathu zamadzi, takulandirani kuti mulankhule nafe.
