Ubi ngwa
Kwesịrị ekwesị maka ụlọ ọrụ na-ahụ maka nsị mmiri nke ime obodo, ụdị mmiri ọ bụla nke ụlọ ọrụ mmiri na-ekpofu mmiri, ibipụta na ịcha akwa mmiri, mmiri na-ekpofu ahịhịa, mmiri na-ekpofu nri na ọgwụgwọ mmiri mkpofu ụlọ ọrụ ndị ọzọ.
Isi Ọrụ
1. Onye nnọchi anya ahụ nwere ike ịmụba ngwa ngwa na sistemu biochemical ma na-eto bio-film na padding, ọ na-ebufe amonia nitrogen na cnitrite n'ime mmiri mkpofu na nitrogen na-adịghị emerụ ahụ nke nwere ike ịhapụ mmiri, iji mebie amonia nitrogen na mkpokọta nitrogen ngwa ngwa. Mbelata ntọhapụ nke isi, na-egbochi uto nke nje bacteria na-emebi emebi, na-ebelata methane, amonia na hydrogen sulfide, na-ebelata mmetọ ikuku.
2. The gị n'ụlọnga na nitrifying nje bacteria, ike ebelata domestication nke arụ ọrụ sludge na si-film oge, ọsọ-elu mmalite nke nsị mkpofu usoro, ibelata n'efu mmiri obibi oge, na-emeziwanye ngụkọta nhazi ike.
3. Dose nitrifying bacteria n'ime mmiri mkpofu, nwere ike melite n'efu mmiri amonia nitrogen nhazi arụmọrụ site 60% na ndabere nke mbụ, na-enweghị na-agbanwe ọgwụgwọ usoro. Ọ nwere ike belata ọnụ ahịa nhazi, bụ enyi na enyi gburugburu ebe obibi, arụmọrụ dị elu, onye na-ahụ maka nje bacteria microbiology.
Usoro ngwa
Dị ka mmiri quality index si biochemical usoro nke ulo oru mkpofu mmiri:
1. Usoro ọgwụgwọ mbụ bụ ihe dị ka 100-200 grams / cubic (dị ka mgbako olu ọdọ mmiri biochemical).
2. The onunu ogwu nke ndepụta mmiri usoro mere site fluctuations kwa nnukwu mmetụta na mma biochemical usoro bụ 30-50 grams / cubic (dị ka biochemical ọdọ mmiri olu mgbako).
3. The onunu ogwu nke obodo mkpofu mmiri bụ 50-80 grams / cubic (dị ka biochemical ọdọ mmiri ngụkọta oge)
Nkọwapụta
Nnwale ndị a gosipụtara na usoro anụ ahụ na kemịkalụ ndị a maka uto nje bụ nke kachasị dị irè:
1. pH: Nkezi dị n'etiti 5.5 ruo 9.5, ọ ga-eto ngwa ngwa n'etiti 6.6 -7.4, na PH kacha mma bụ 7.2.
2. Okpomọkụ: Were mmetụta n'etiti 8 ℃ - 60 ℃. Bacteria ga-anwụ ma ọ bụrụ na okpomọkụ dị elu karịa 60 ℃. Ọ bụrụ na ọ dị ala karịa 8 ℃, nje bacteria agaghị anwụ, mana uto nke nje bacteria ga-egbochi ọtụtụ. Okpomọkụ kachasị mma bụ 26-32 ℃.
3. Oxygen agbazere: Aeration tank na nsị na-edozi, ikuku oxygen na-agbaze bụ ma ọ dịkarịa ala 2 mg / liter. The metabolic na regrade rate of bacteria can speed up by 5-7times na zuru oxygen.
4. Micro-Elements: Ndị otu nje bacteria ga-achọ ọtụtụ ihe na uto ya, dị ka potassium, iron, calcium, sọlfọ, magnesium, wdg, ọ na-enwekarị ihe ndị a kpọtụrụ aha na ala na mmiri.
5. Salinity: Ọ bụ ọdabara na mmiri nnu dị elu, oke nnabata nke salinity bụ 6%.
6. Nguzogide nsi: Ọ nwere ike iguzogide ihe ndị na-egbu egbu nke kemịkalụ, gụnyere chloride, cyanide na ọla dị arọ, wdg.
* Mgbe ebe mmetọ nwere biocide, ọ dị mkpa ịnwale mmetụta nje bacteria.
