Hobaneng Taolo e Nepahetseng ea Maemo e le ea Bohlokoa ho WWTPs
Kalafo ea metsi a litšila ke ts'ebetso e latellanang, 'me mohato ka mong o itšetlehile ka maemo a tsitsitseng a metsi ho sebetsa hantle. Nahana ka mekhahlelo e 'meli ea bohlokoa:
- Libasine tsa ho sesa: Litanka tsena li lumella lintho tse tiileng (joalo ka seretse) ho lula tlase. Haeba boemo ba mokelikeli bo le holimo haholo, bese e tlala, e romela lintho tse tiileng tse sa phekoloang lits'ebetsong tse tlase kapa esita le metsing a lehae. Haeba maemo a le tlase haholo, nako ea ho sesa e ea fokotseha, 'me lintho tse tiileng li lula li emisitsoe - ho beha boleng ba metsi a hloekisitsoeng kotsing.
- Ditanka tsa Moya: Mona, dikokwana-hloko di qhaqha dintho tse phelang ka thuso ya oksijene. Boemo ba mokelikeli bo lokela ho dula bo le sebakeng se senyenyane ho netefatsa hore di-diffuser tsa moya di qoeditswe ka botlalo (ho eketsa phetiso ya oksijene) le ho thibela tanka hore e se ke ya oma (e leng se senyang dipompo le ho sitisa tikoloho ya dikokwana-hloko).
Ntle le tlhokomelo e nepahetseng ea boemo, WWTPs e itšetleha ka liteko tsa letsoho— ts'ebetso e liehang, e sekametseng ho etsa liphoso e sa khoneng ho tsamaisana le liphetoho tse fetohang tsa phallo (mohlala, pula e matla e eketsang phallo ea metsi a litšila). Limithara tsa boemo li felisa khakanyo ena, li fetola liphetoho tse arabelang hore e be taolo e sebetsang.
Theknoloji ea Limithara tsa Maemo a Bohlokoa bakeng sa Tikoloho ea WWTP
Li-WWTP li hlahisa liphephetso tse ikhethang bakeng sa limithara tse bataletseng: metsi a litšila hangata aa senya, a na le lintho tse tiileng kapa lipululana, 'me litanka li ka ba kholo kapa tsa ba thata ho li fihlela. Mahlale a sebetsang hantle ka ho fetisisa a etselitsoe maemo ana:
- Methara ea Maemo a Ultrasonic: Lisebelisoa tse sa amaneng le metsi tse ntšang maqhubu a molumo ho lekanya sebaka ho tloha ho sensor ho ea holim'a metsi. Li sebetsa hantle litankeng tse bulehileng (mohlala, libasine tsa sedimentation) 'me li qoba ho kopana le metsi a litšila a senyang kapa a tletseng lintho tse tiileng, e leng se fokotsang litlhoko tsa tlhokomelo.
- Limithara tsa Boemo ba Radar: Sebelisa matšoao a microwave ho lemoha maemo a metsi, a fanang ka ho nepahala ho hoholo esita le maemong a thata (mohlala, mongobo o phahameng, foam, kapa lerōle). Li loketse litanka tse koetsoeng (mohlala, polokelo ea lik'hemik'hale bakeng sa ho bolaea likokoana-hloko) kapa litanka tse nang le libaka tse ferekantsoeng.
- Li-Transmitter tse ka Keneloang ka Tlase: Li kentsoe ka ho toba metsing a litšila, limithara tsena li lekanya khatello (e amanang le botebo ba metsi). Li tšoarella bakeng sa tšebeliso ea nako e telele likamoreng tsa lehlohlojane kapa litankeng tsa seretse, moo lintho tse tiileng li leng ngata.
Theknoloji e 'ngoe le e 'ngoe e sebetsana le litlhoko tse ikhethileng tsa WWTP—mohlala, li-ultrasound metres li qoba ho koaleha ka har'a libaskete tse nang le lithōle tse phaphametseng, ha li-radar metres li khaola foam ka har'a litanka tsa moea ho fana ka lipalo tse tšepahalang.
Kamoo Methara ea Maemo e Ntlafatsang Bokgoni ba Ts'ebetso
Lintlha tse nepahetseng tsa boemo ha li thibele liphoso feela—li ntlafatsa katleho ea WWTP ka litsela tse tharo tsa bohlokoa:
- Tšebeliso e Ntlafalitsoeng ea Matla: Lipompo le li-aerator ke tse ling tsa basebelisi ba matla ba bangata ho WWTPs. Limithara tsa maemo li fetola litsamaiso tsena ka nako ea sebele: haeba boemo ba tanka bo theoha, mithara e fana ka lets'oao la ho fokotsa lebelo la pompo (ho boloka matla), 'me haeba maemo a phahama, e eketsa moea ho lekana le tlhoko. Lithuto li bontša hore sena se ka fokotsa litšenyehelo tsa matla ka 10-15%.
- Nako e Fokotsang ea Tlhokomelo: Liteko tsa maemo a matsoho li hloka hore basebetsi ba fihle libakeng tse koetsoeng kapa tse kotsi (mohlala, li-tank top), ho eketsa likotsi tsa polokeho le nako ea basebetsi. Limithara tsa maemo li romela data hole ho ea likamoreng tsa taolo, e leng se felisang tlhoko ea liteko tse etsoang khafetsa sebakeng seo. Li boetse li baka litemoso tsa ho se tsitse (mohlala, ho phahama ha maemo ka tšohanyetso), ho lumella lihlopha ho lokisa mathata (joalo ka phaephe e koetsoeng) pele a baka nako ea ho se sebetse.
- Ho latela Melao ea Taolo: Mekhatlo ea tikoloho e hloka hore WWTP e latele le ho tlaleha lintlha tsa ts'ebetso ea kalafo—ho kenyeletsoa le maemo a metsi. Limithara tsa maemo li boloka lintlha tsa nalane (mohlala, mekhoa ea maemo a letsatsi le letsatsi) tse ka arolelanoang habonolo nakong ea tlhahlobo, e leng se fokotsang kotsi ea likotlo tsa ho se latele melao.
