Ngwa nke sodium acetate n'ime ụlọ na-agwọ nsị,
Ihe ngwọta sodium acetate nke China, Ndị na-eweta sodium acetate nke China, Sodium acetate, sodium acetate mmetụta, sodium acetate mmetụta na ojiji, Ndị na-emepụta sodium acetate, Sodium acetate ngwọta, ndị na-emepụta ihe ngwọta sodium acetate, ndị na-ebu sodium acetate, A na-eji sodium acetate eme ihe,
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 acetate na-arụ ọrụ dị mkpa n'ịchịkwa uru PH na ọgwụgwọ nsị. Sodium acetate bụ ihe kemịkalụ alkaline nke enwere ike ime ka ọ mepụta ions OH na-adịghị mma na mmiri, nke nwere ike imebi ion bai acid na mmiri, dị ka H +, NH4+, wdg. , ma ị maara otú e si eji ya? Taa, obere mbipụta nke Hebei Pengfa ga-akparịta ụka gị.
Nke mbụ, a naghị eji sodium acetate eme ihe na ụlọ ọrụ ọgwụgwọ mmiri, a na-eji ya eme ihe mgbe niile na ụlọ ọrụ obibi akwụkwọ na ịcha akwa. Naanị n'ihi na ụlọ ọrụ ọgwụgwọ mmiri na-eto eto na afọ ndị na-adịbeghị anya, na enwere ezigbo mkpa sodium acetate iji melite ebumnuche ọgwụgwọ nsị. Ọ bụ ya mere eji eji ya na ụlọ ọrụ nsị. A na-eji sodium acetate mee ihe dị ka ihe mgbakwunye carbon iji mee ka sludge denitrification dị elu, na mgbe ahụ, a na-eji ngwọta nchekwa iji chịkwaa ịrị elu nke uru pH na usoro denitrification n'ime 0.5 nso. 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. Ka ọ dị ugbu a, ọgwụgwọ nsị mmiri niile nke obodo na mpaghara iji mezuo ụkpụrụ mkpofu chọrọ mgbakwunye sodium acetate (sodium acetate) dị ka isi iyi carbon.
