Ubumenyi nogukoresha uburyo bwo gutunganya umwanda

I.Imyanda ni iki?

Umwanda w'amazi bivuga amazi asohoka mu bikorwa no mu buzima. Abantu bakoresha amazi menshi mubuzima bwa buri munsi nibikorwa byumusaruro, kandi aya mazi akenshi aba yanduye kuburyo butandukanye. Amazi yanduye yitwa imyanda.

II. Nigute dushobora gutunganya imyanda?

Gutunganya umwanda bikubiyemo gukoresha tekinoloji nuburyo butandukanye bwo gutandukanya, gukuraho, no gutunganya imyanda ihumanya imyanda cyangwa kuyihindura mubintu bitagira ingaruka, bityo kweza amazi.

III.Gusaba kuvura ibinyabuzima mu myanda?

Gutunganya ibinyabuzima byangiza imyanda bifashisha ubuzima bwa mikorobe kugirango bikureho neza ibinyabuzima byangirika hamwe n’ibintu bimwe na bimwe bitangirika mu mazi y’amazi, bisukura amazi.

IV.Gusobanura bagiteri zo mu kirere na anaerobic?

Bagiteri zo mu kirere: Bagiteri zisaba ko habaho ogisijeni yubusa cyangwa idakurwaho imbere ya ogisijeni yubusa. Bagiteri ya Anaerobic: Bagiteri idasaba ogisijeni yubusa cyangwa idakurwaho iyo nta ogisijeni yubusa ihari.

V. Isano iri hagati yubushyuhe bwamazi nigikorwa?

Ubushyuhe bwamazi bugira ingaruka zikomeye kumikorere ya tanks. Mu ruganda rutunganya imyanda, ubushyuhe bwamazi burahinduka buhoro buhoro nibihe kandi ntibishobora guhinduka mugihe cyumunsi. Niba hari impinduka zikomeye zibonetse mumunsi umwe, hagomba gukorwa igenzura kugirango amazi akonje mu nganda yinjira. Iyo ubushyuhe bwamazi yumwaka buri hagati ya 8-30 ℃, uburyo bwo kuvura ikigega cya aeration buragabanuka iyo bukora munsi ya 8 and, kandi igipimo cyo gukuraho BOD5 akenshi kiri munsi ya 80%.

VI.Imiti isanzwe ikoreshwa mugutunganya imyanda?

Acide: Acide sulfure, aside hydrochloric, aside aside.

Alkalis: Lime, hydroxide ya sodium (soda ya caustic).

Flocculants: Polyacrylamide.

Coagulants: Choride ya Poly Aluminium, sulfate ya aluminium, chloride ferric.

Oxidants: Hydrogen peroxide, sodium hypochlorite.

Kugabanya imiti: Sodium metabisulfite, sodium sulfide, sodium bisulfite.

Ibikoresho bikora: Gukuraho azote ya Amoniya, kuvanaho fosifore, icyuma kiremereye, decolorizer, defoamer.

Ibindi bikoresho: Inhibitor ya Scale, demulsifier, aside citric.
