Bitewe nihinduka ryibintu bimwe na bimwe, ubwiza bwamazi bwakoreshejwe buba bworoshye, bwagutse, kandi imikorere yo gutuza ikagenda yangirika, agaciro ka SVI gakomeje kwiyongera, kandi gutandukanya ibyondo n’amazi bisanzwe ntibishobora gukorwa mu kigega cya kabiri cy’imyanda.Urwego rwo kumeneka rwikigega cya kabiri rwimyanda ikomeje kwiyongera, amaherezo umwanda uratakara, kandi kwibanda kwa MLSS mubigega bya aeration byagabanutse cyane, bityo bikangiza imyanda mubikorwa bisanzwe.Iyi phenomenon yitwa sludge bulking.Amashanyarazi menshi ni ibintu bidasanzwe muri sisitemu ikora ya sisitemu.
Igikorwa cyo kumena amashanyarazi gikoreshwa cyane mugutunganya amazi mabi.Ubu buryo bwageze ku musaruro mwiza mu gutunganya amoko menshi y’amazi mabi nk’imyanda ya komini, gukora impapuro no gusiga amarangi y’amazi, kugaburira amazi y’amazi n’amazi yanduye.Nyamara, hari ikibazo gikunze kugaragara mugukora sludge ivura, ni ukuvuga, guswera byoroshye kubyimba mugihe cyo gukora.Kuvunika imyanda bigabanijwemo cyane cyane ubwoko bwa bagiteri zo mu bwoko bwa sludge bulking na bacteri zo mu bwoko bwa silige nyinshi, kandi hariho impamvu nyinshi zitera.Ingaruka zo kumeneka zirakomeye cyane, iyo bibaye, biragoye kugenzura, kandi igihe cyo gukira ni kirekire.Niba ingamba zo kugenzura zidafashwe mugihe, igihombo gishobora kubaho, byangiza cyane imikorere yikigega cya aeration, bikaviramo gusenyuka kwa sisitemu yose yo kuvura.
Ongeramo calcium chloride irashobora kubuza gukura kwa bagiteri zanduye, zifasha gukora mikorobe ya bagiteri, no kunoza imikorere yimitsi.Kalisiyumu ya chloride izabora kandi itange ioni ya chloride nyuma yo gushonga mumazi.Iyoni ya Chloride igira ingaruka no kwanduza amazi, ishobora kwica igice cya bagiteri kandi ikabuza kubyimba imyanda iterwa na bagiteri.Nyuma yo guhagarika kongeramo chlorine, ion ya chloride nayo irashobora kuguma mumazi umwanya muremure, kandi bagiteri zandura ntizikura cyane mugihe gito, kandi mikorobe irashobora gukomeza gukora floc isanzwe, ibyo bikaba byerekana kandi ko kwiyongera calcium chloride irashobora kubuza imikurire ya bagiteri kandi ifite ingaruka nziza mugukemura kubyimba.
Ongeramo calcium chloride irashobora kugenzura kubyimba vuba kandi neza, kandi SVI ya siliveri ikora irashobora kugabanuka vuba.SVI yagabanutse kuva 309.5mL / g igera kuri 67.1mL / g nyuma yo kongeramo calcium chloride.Utarinze kongeramo calcium chloride, SVI ya siliveri ikora nayo irashobora kugabanuka muguhindura imikorere, ariko igipimo cyo kugabanuka kiratinda.Ongeramo calcium chloride nta ngaruka zigaragara ku gipimo cyo gukuraho COD, kandi igipimo cyo gukuraho COD cyo kongeramo calcium chloride kiri munsi ya 2% ugereranije no kutongera chloride ya calcium.
