Sewage no gusesenguraKuvura imyandani inzira yo gukuraho byinshi mubyatsi biva mu mazi cyangwa imyanda kandi bikabyara efleluent y'amazi akwiriye kunyuramo n'ibidukikije. Kugira ngo ugire akamaro, imyanda igomba gutwarwa mu kuvura ibihingwa bikwiye no mu bikorwa remezo, kandi inzira ubwayo igomba kugenzurwa no kugenzurwa. Andi manda akunze gusaba uburyo butandukanye kandi rimwe na rimwe buti kuvura. Muburyo bworoshye bwo kuvura no kuvura amazi menshi, ibinini mubisanzwe bitandukanijwe n'amazi akemura. Itanga imigezi yingengabihe yo kongera isuku ihinduka buhoro buhoro ibikoresho byashonze kugirango bihuze, ubusanzwe biota, hanyuma ubigenderaho.

Bigenda bikunze kugaragara mubihugu byateye imbere kugabanya amazi yo murugo mumazi yijimye kandi yirabura, hamwe namazi meza yemerewe ibihingwa byamazi cyangwa bisubirwamo kugirango ahindure ubwiherero. Sewage nyinshi nayo ikubiyemo amazi yo hejuru hejuru yinzu cyangwa ahantu hakomeye. Rero, amazi yamazi akubiyemo guturamo, ubucuruzi, ninganda, kandi irashobora kandi kubamo amafaranga yahohotewe.

Ibipimo rusange:

· Bord (ibinyabuzima bya ogisijeni)

· Cod (Ibisabwa bya ogisijeni)

· MLSS (amazi avanze yahagaritswe kuri socide)

· Amavuta na grease

· Ph

· Gutwara

· Yosese Yuzuye

Bod (ibinyabuzima bya ogisijeni):

Ibinyabuzima bya ogisijeni, cyangwa bod, ni umubare wa ogisijeni washeshwe mubinyabuzima bya aerobic mumazi kugirango uboherereze amazi ngengabuzima aho igihe runaka. Iri jambo ryerekeza kandi ku nzira za shimi zikoreshwa mu kumenya amafaranga. Ibi ntabwo ari ikizamini nyacyo, nubwo gikoreshwa cyane nkikimenyetso cyerekana ubuziranenge bwamazi. BOD irashobora gukoreshwa nkigipimo cyo gupima imikorere yibiti byo kuvura amazi. Itondekanya nkuko bisanzwe mu bihugu byinshi.

Cod (imiti ya chimique ogisijeni):

Mu rwego rw'ibidukikije, ikizamini cya ogisijeni cya oxygen (Cod) gikoreshwa mu buryo butaziguye gipima umubare w'ibinyabuzima by'amazi. Ibipimo byinshi bya code byerekana umubare wibibazo bya kama usanga mumazi yo hejuru (nkibiyaga ninzuzi) cyangwa amazi meza, bigatuma ari code ikimenyetso cyingirakamaro cyubwiza bwamazi. Guverinoma nyinshi zashyizeho amabwiriza akomeye kuri ogisige ntarengwa ya ogisijeni yemereye mu mazi mbere yuko isubizwa mu bidukikije.

Isosiyete yacuyinjira mu nganda zicuruza amazi kuva mu 1985 utanga imiti n'ibisubizo ku bwoko bwose bw'inganda n'inganda zo kuvura imyanda. Turi abakora imiti yo gutunganya amazi, harimoPolyethylene Glycol-Peg.
