Ukwelashwa kwe-Microbial kokuthuthwa kwendle ukuhambisa izinhlaka zendle ezisebenza ngensimbi, okukhuthaza ukwakheka okusheshayo komoya olinganiselayo emzimbeni wamanzi uqobo, lapho kungekho kuphela ama-demomeser, abakhiqizi kanye nabathengi. Ukungcola kungalashwa futhi kusetshenziswe kahle, futhi ngaleyo ndlela kwakhiwa amaketanga amaningi okudla, akha i-ecosystem yokudla okuwela i-Criss-ewela i-web. Uhlelo oluhle futhi oluzinzile lwemvelo lungasungulwa uma inani elifanele kanye nezilinganiso zamandla zigcinwa phakathi kwamazinga we-trophic. Lapho inani elithile lokukhucululwa kwendle lingena kulolo hlelo, ukungcoliswa kwemvelo kulo akuwonakaliswa kuphela futhi kuhlanjululwe ngamagciwane kanye nesikhunta, kusetshenziswa imithombo ye-photobor, futhi amandla elanga kanye nemithombo ye-pholar, futhi kusetshenziswa umthombo wamandla wokuqala. , hlanganyela kwinqubo ye-metabolic kuwebhu yokudla, futhi kancane kancane uthuke futhi uguqule kusuka ezingeni eliphansi le-trophic liye ezingeni eliphakeme le-trophic, futhi ekugcineni uguqule, ungeze izinyathelo zokugcina ubuhle bemvelo, futhi ungeze injongo yokuvimbela nokulawula i-eutrophication yomzimba wamanzi.
1. Ukwelashwa kwe-Microbial kokuthuthwa kwendleKakhulu isusa ukungcoliswa kwe-organic (i-bod, ama-cod) eColloidal futhi incibilike i-colloidal futhi incishisiwe ekukhuculweni kwendle, futhi isilinganiso sokususa singafinyelela ngaphezu kwama-90%, ukuze ukungcoliswa kwe-organic kungahlangabezana nendlela yokuphuma.
. Ngokuvamile kubhekiswa engxenyeni yezinto eziphilayo ezingenangqondo eziqukethwe ku-1l yokuthuthwa kwendle noma isampula lamanzi ukuze ihlolwe. Lapho ama-microorganisms oxidize futhi ebola, umoya-mpilo oncibilikisiwe emanzini adliwe kuma-milligrams (iyunithi yi-MG / L). Izimo zokulinganisa ze-bod zivame ukucaciswa ngo-20 ° C ngezinsuku ezi-5 nobusuku, ngakho-ke uphawu lwe-Bod5 luvame ukusetshenziswa.
. (Iyunithi yi-MG / L). Ama-oxidants ajwayelekile asetshenziswa ngamakhemikhali angu-K2CR2O7 noma KMNO4. Phakathi kwazo, i-K2CR2O7 isetshenziswa kakhulu, futhi i-COD elinganisiwe imelelwa yi- "Cod Cr".
2. I-Microbial Treatment Poage ihlukaniswe ngohlelo lokwelashwa kwe-aerobic kanye nohlelo lokwelashwa kwe-anaerobic ngokwesimo se-oxygen kwinqubo yokwelashwa.
1. I-Aerobic Treatment System
Ngaphansi kwezimo ze-aerobic, ama-microorganisms adsgorb udaba lwemvelo emvelweni, oxidize futhi abolile abe yi-inorganic, ahlaze indle, futhi ahlanganise udaba lwasemakhalekhukhwini ngasikhathi sinye. Enqubweni yokuhlanzwa kwendle, ama-microorganisms akhona ngendlela evuliwe yi-sludge evuliwe kanye nezinto eziphambili ze-biofilm.
Le ndlela iyindlela yokwelashwa ephilayo nge-biofilm njengomzimba oyinhloko wokuhlanzwa. I-Biofilm ingulwelwesi lwe-mucous olunamathiselwe ebusweni bomthwali futhi ikakhulukazi owakhiwa yi-bacterial minelles. Umsebenzi we-bioflilm uyefana naleso soludge ocushiwe kwinqubo esetshenzisiwe ye-sludge, futhi ukwakheka kwalo kwe-microbial kuyafana. Umgomo oyinhloko wokuhlanzwa kwendle yi-adsorption kanye nokuwohloka kwe-oxidative of organic ku-secures nge-biofilm enamathiselwe ebusweni bomthwali. Ngokwezindlela ezahlukahlukene zokuxhumana phakathi kwephakathi nendawo namanzi, indlela ye-biofilm ifaka indlela yemvelo kanye nendlela yombhoshongo wokuhlunga.
3. Uhlelo lokwelashwa kwe-anaerobic
Ngaphansi kwezimo ze-anoxic, indlela yokusebenzisa ama-bacterium anaerobic (kufaka phakathi ama-bacterobic anaerobic) ukuwathela ukungcola kwe-organic ekukhuculweni kwendle nakho okubizwa ngokuthi ukugaya i-anaerobic noma ukuvutshelwa kwe-anaerobic. Ngoba umkhiqizo we-Fermentation ukhiqiza i-methane, kubizwa nangokubizwa nge-methane Fermentation. Le ndlela ayikwazi ukuqeda ukungcoliswa kwemvelo kuphela, kepha futhi ithuthukisa amandla e-bio-amandla, ngakho-ke abantu banaka kakhulu. Ukuvulwa kwe-anaerobic kokuthuthwa kwendle kuyinkimbinkimbi kakhulu yemvelo, okubandakanya ukushintshana kwamaqembu ahlukahlukene, ngakunye okudinga ama-substrate ahlukene nemibandela, ekwakheni isimo semvelo esiyinkimbinkimbi. I-Methane Fermentation ifaka izigaba ezintathu: Isigaba se-Liquefaction, ukukhiqizwa kwe-hydrogen kanye nesigaba sokukhiqiza acijile kanye nesigaba sokukhiqiza se-methane.
Ukwelashwa kwendle kungahlukaniswa ekwelashweni okuyisisekelo, ngokwesiko nangokwezemfundo ephakeme ngokuya ngezinga lokwelashwa.
Ukwelashwa Okuyisisekelo: Kususa ikakhulukazi ukuvalwa okuqinile okusongelwa indle ukuthuthwa kwendle, futhi iningi lezindlela zokwelashwa ngokomzimba zingaqedela kuphela izidingo zokwelashwa okuyinhloko. Ngemuva kokuphathwa kokuthuthwa kwendle, umzimba ngokuvamile kungasuswa cishe ngama-30%, angahlangabezani nezindlela zokuphuma. Ukwelashwa okuyisisekelo kungokwakheka kokwelashwa kwesibili.
Inqubo yokuqala yokwelashwa yile: Ukuthuthwa kwendle okuluhlaza okwedlule ngegridi yama-coarse kuphakanyiswa yi-send lift yokuthuthwa kwendle - kudlule i-grid noma indle kungena ethangini eliyisisekelo - okungenhla kungena: ukucubungula okuyisisekelo (ukucubungula ngokomzimba). Umsebenzi we-grit Chamber ukususa izinhlayiya ezingaphakathi ngokudonsela phansi okukhulu. Ama-grit amagumbi ajwayelekile asetshenziswa ngamagumbi athunyelwa nge-grit, amagumbi e-aerated grit, amakamelo we-dole grit kanye namagumbi e-bell-hlobo grit grit.
Ukwelashwa kwesibili: Isusa ikakhulukazi i-colloidal futhi inciphise i-organic pollaturants (bod, ama-cod, ama-cod) ekuthundleweni indle, futhi isilinganiso sokususa singafinyelela ngaphezu kwama-90%, ukuze ukungcola kwe-organic kungafinyelela izinga lokuphuma.
Inqubo yokwelashwa yesibili yile: Amanzi aqhamuka ethangini eliyisisekelo sedimentation angena kwizinto zokwelashwa eziphilayo, okubandakanya indlela ye-slidege esebenzayo kanye ne-biofilm indlela ye-axiofilm, amanzi ashibhile, aphuma embhedeni we-biofilge afaka phakathi kwemishini yokwelashwa Ithangi, kanye ne-effluent ethangi lokudonsela phansi kwesibili likhishwa ngemuva kokubulala amagciwane noma ukungena ekwelapheni okuphezulu.
Ukwelashwa kweTertiary: Kakhulu bhekana kahle nezinkinga ze-organic ezisebenzayo, udaba lwe-innorganic olufana ne-nitrogen ne-phosphorus engaholela
ukufika emzimbeni wamanzi. Izindlela ezisetshenzisiwe zifaka phakathi ukudifizwa kwemvelo kanye nokususwa kwe-phosphorus, ukususwa kwe-cooaciment, indlela yesitabane ye-carbon adsortion, indlela yokushintshanisa ye-carboosmosis kanye nendlela yokuhlaziywa kwe-elektrososos
Inqubo yokwelashwa yemfundo ephakeme imi ngale ndlela elandelayo: Ingxenye ye-sludge ethangini le-sedimentation ye-sedimentation iyabuyiselwa emathangini asemqoka e-sedimentation noma imishini yokwelashwa, futhi ingxenye ye-sludge ingena ithangi lokugaya i-sludge, bese lifaka ithangi lokugaya i-sludge. Ngemuva kwemishini yokuxoxa nezemisiwe, i-sludge ekugcineni isetshenziswa.
Noma ngabe kungumthengi omusha noma umthengi wakudala, sikholelwa emklamweni okhethekile wamagciwane e-ammonia elonakala amanzi e-China, ukwanda kwamakhasimende athembekile, semukela i-imeyili yokuxhumana nathi ngefoni ephathekayo noma ukuthumela i-imeyili ukuze sisuse izinhlangano zebhizinisi lesikhathi eside nempumelelo eyabiwe.
Ukulashwa kwamakhemikhali wamanzi amdakaI-China Bacteria Design, i-ejenti yamanzi e-bacterium, njengomsebenzi ofundile, ofundisayo futhi onamandla, besiphethe zonke izinto zocwaningo, design, ukukhiqiza, ukuthengisa nokusabalalisa. Ngokucwaninga nokwakha ubuchwepheshe obusha, asilandeli nje kuphela kepha sihole imboni yezemfashini. Silalela ngokucophelela impendulo yamakhasimende futhi sinikeze ukuxhumana okusheshayo. Uzozizwa ngokushesha ubuchwepheshe bethu nokunaka.
