Ọrụ na ntinye nke sodium acetate na ọgwụgwọ mmiri mkpofu,
Liquid Sodium Acetate, mmiri mmiri sodium acetate mmetụta, ndị na-emepụta sodium acetate mmiri mmiri, Mmiri sodium acetate na-eji, Ndị na-emepụta sodium acetate,
1. Isi ihe ngosi:
Ọdịnaya: ≥20%, ≥25%, ≥30%
Ọdịdị: mmiri mmiri doro anya na nke doro anya, enweghị isi na-akpasu iwe.
Ihe na-adịghị edozi mmiri: ≤0.006%
2. Isi ebumnuche:
Iji gwọọ nsị mmiri n'obodo mepere emepe, mụọ mmetụta nke afọ sludge (SRT) na isi iyi carbon mpụga (sodium acetate solution) na denitrification sistemu na mwepụ nke phosphorus. A na-eji sodium acetate eme ihe dị ka ihe mgbakwunye carbon iji mebie sludge denitrification, wee jiri ngwọta nchekwa iji chịkwaa mmụba nke pH n'oge usoro denitrification n'ime oke nke 0.5. Nje bacteria na-emebi emebi nwere ike ịgbasa CH3COONa nke ukwuu, yabụ mgbe ị na-eji CH3COONa dị ka isi iyi carbon mpụga maka denitrification, uru COD na-asọpụta nwekwara ike idowe ya na ọkwa dị ala. Ka ọ dị ugbu a, ọgwụgwọ nsị na obodo niile na mpaghara niile kwesịrị ịgbakwunye sodium acetate dị ka ikuku carbon iji zute ụkpụrụ mgbapụta ọkwa ọkwa mbụ.

Sodium sulfate ngwaahịa na-ekewa n'ime siri ike na mmiri mmiri ụdị abụọ, siri ike sodium acetate C2H3NaO2 ọdịnaya ≥58-60%, ọdịdị: enweghị colorless ma ọ bụ na-acha ọcha transperent crystal. Mmiri sodium acetate ọdịnaya: ọdịnaya ≥20%, 25%, 30%. Ọdịdị: mmiri mmiri doro anya na nke na-enweghị atụ. Sensory: enweghị isi na-akpasu iwe, mmiri na-adịghị ike: 0.006% ma ọ bụ obere.
Ngwa: A na-eji sodium acetate eme ihe dị ka ihe mgbakwunye carbon na ụlọ ọrụ na-ahụ maka nsị mmiri iji mee ka sludge denitrification dị elu, nke nwere ike nweta ọnụ ọgụgụ denitrification dị elu. Ka ọ dị ugbu a, ihe niile dị n'ime ime obodo ma ọ bụ ọgwụgwọ mmiri mkpofu nke ụlọ ọrụ iji zute ọkwa mwepụta A ọkọlọtọ chọrọ mgbakwunye sodium acetate dị ka isi iyi carbon.
1. Ọ tumadi na-arụ ọrụ nke ịchịkwa PH uru nke nsị. Ọ nwere ike hydrolyze na mmiri ka ọ bụrụ ion na-adịghị mma nke OH, nke nwere ike wepụ ions acidic na mmiri, dị ka H+, NH4+ na ndị ọzọ. Ngụkọta hydrolysis bụ: CH3COO-+H2O= reversible =CH3COOH+OH-.
2. Dị ka ihe mgbakwụnye carbon, a na-eji ngwọta nchekwa iji chịkwaa ịrị elu nke uru pH n'ime 0.5 na usoro denitrification. Ihe nje bacteria na-emebi emebi nwere ike imebi CH3COONa, ya mere enwere ike idowe uru COD nke nsị na ọkwa dị ala mgbe a na-eji CH3COONa dị ka ihe mgbakwunye carbon maka denitrification. Ọnụnọ nke acetate sodium ugbu a na-edochi isi iyi carbon gara aga, na sludge mmiri na-arụ ọrụ karịa mgbe ejiri ya.
3. Ọ na-arụ ọrụ dị mkpa na nkwụsi ike nke àgwà mmiri. Na nsị nke nitrite na phosphorus, enwere ike iji ya mee ihe maka nhazi nhazi, nke nwere ike imeziwanye ike nke mgbochi corrosion. Ọ bụrụ na a na-eme ule ahụ na mmiri mmiri dị iche iche, a pụrụ iji obere ego sodium acetate nke ụlọ ọrụ mmepụta ihe mee ihe mbụ iji nweta usoro kwesịrị ekwesị. Ọtụtụ mgbe, usoro mmepụta nke ụlọ ọrụ ahụ ga-abụ ihe siri ike na mmiri nke 1 ruo 5, iji mezue usoro mgbasa ozi tupu ị gbakwunye mmiri maka dilution.
