Kugeza ubu, amazi asanzwe COD irenze igipimo gikubiyemo ahanini amashanyarazi, ikibaho cy’umuzunguruko, gukora impapuro, imiti, imyenda, icapiro no gusiga irangi, imiti n’andi mazi mabi, none ni ubuhe buryo bwo gutunganya amazi y’amazi ya COD? Reka tujye kurebera hamwe.
Amazi y’imyanda COD.
Inkomoko y’amazi y’umusaruro agabanijwemo: amazi y’inganda, amazi y’ubuhinzi, n’amazi y’ubuvuzi.
Umwanda wo mu ngo bivuga uruvange rugoye rwubwoko butandukanye bwibinyabuzima bigizwe n’ibinyabuzima n’ibinyabuzima, harimo:
Kureremba cyangwa guhagarikwa binini kandi bito bikomeye
OlColloidal na gel-isa na diffusers
Solution Igisubizo kiboneye.
Uburyo bwo gutunganya amazi mabi ya COD arimo:
Gukuraho COD hakoreshejwe uburyo bwa coagulation: uburyo bwa coagulation chimique burashobora gukuraho neza ibintu kama mumazi mabi kandi bikagabanya COD kurwego runini. Igikorwa cya coagulation cyemejwe, mukongeramo flocculant, ukoresheje adsorption hamwe nikiraro cya flocculant, amashanyarazi abiri yumuriro arahagarikwa, kuburyo ibintu bya colloid nibihagarikwa mumazi bihungabana, bikagongana, bikabundira mubibabi, hanyuma bikinjira cyangwa ikirere. inzira ya flotation ikoreshwa mugukuraho Ibice bitandukanijwe namazi, kugirango bigere ku ntego yo kweza umubiri wamazi.
Uburyo bwa biologiya bwo gukuraho COD: Uburyo bwibinyabuzima nuburyo bwo gutunganya amazi mabi bushingiye kumisemburo ya mikorobe kugirango oxyde cyangwa igabanye ibintu kama kugirango isenye imigozi idahagije hamwe na chromofore kugirango igere ku ntego yo kuvura. Mu myaka ya vuba aha, ibinyabuzima byakoreshejwe cyane mu gutunganya amazi y’amazi bitewe n’umuvuduko w’imyororokere wihuse, guhuza n'imihindagurikire y’ibiciro ndetse n’igiciro gito.
Gukuraho amashanyarazi ya COD: Intego yo gutunganya amazi y’amashanyarazi ni ugukoresha electrolysis mu buryo butaziguye cyangwa butaziguye kugira ngo ikureho umwanda mu mazi, cyangwa guhindura ibintu by’ubumara ibintu bidafite uburozi n’uburozi buke.
Kurandura COD na micro-electrolysis: Ikoranabuhanga rya Micro-electrolysis kuri ubu ni uburyo bwiza bwo kuvura amazi mabi y’ibanze cyane, azwi kandi nka electrolysis y'imbere. Ivumburwa rikoresha ibikoresho bya micro-electrolysis kugirango yuzuze amazi y’imyanda nta mashanyarazi afite, kandi itanga itandukaniro rya 1.2V yonyine ubwayo kugirango amashanyarazi yanduye imyanda kugirango agere ku ntego yo kwangiza imyanda ihumanya.
Gukuraho COD hakoreshejwe uburyo bwo gukuramo: karubone ikora, macroporous resin, bentonite nibindi bikoresho bya adsorption birashobora gukoreshwa mugutanga amatangazo no kuvura ibintu kama kama na chroma mumyanda. Irashobora gukoreshwa nka pre-treatment kugirango igabanye COD byoroshye gukemura.
Uburyo bwa Oxidation bwo gukuraho COD: Mu myaka yashize, ikoreshwa rya tekinoroji ya fotokatalitike ya okiside mu rwego rwo gutunganya amazi y’amazi afite amahirwe meza ku isoko n’inyungu z’ubukungu, ariko haracyari ibibazo byinshi mu bushakashatsi muri uru rwego, nko gushaka catalizike ikora neza. , gutandukana no kugarura catalizator gutegereza.
