Basa uye kushandiswa kwe sodium acetate mukurapwa kwemvura yakasviba,
Liquid Sodium Acetate, liquid sodium acetate migumisiro, liquid sodium acetate vagadziri, liquid sodium acetate inoshandisa, Vagadziri veSodium acetate,
1. Main zviratidzo:
Zviri mukati: ≥20%, ≥25%, ≥30%
Kuonekwa: mvura yakajeka uye yakajeka, hapana kunhuhwirira kunogumbura.
Mvura isinganyunguriki chinhu: ≤0.006%
2. Chinangwa chikuru:
Kurapa tsvina yemuguta, dzidza pesvedzero yezera remarara (SRT) uye yekunze kabhoni sosi (sodium acetate solution) pane system's denitrification uye phosphorus kubviswa. Sodium acetate inoshandiswa seyekuwedzera kabhoni sosi yekugadzira iyo denitrification sludge, uyezve kushandisa buffer mhinduro kudzora kuwedzera kwepH panguva ye denitrification process mukati meiyo 0.5. Denitrifying mabhakitiriya anogona adsorb CH3COONa zvakanyanyisa, saka kana uchishandisa CH3COONA seyekunze kabhoni sosi ye denitrification, iyo effluent COD kukosha inogona zvakare kuchengetedzwa padanho rakaderera. Parizvino, kurapwa kwetsvina mumaguta ese nemataundi kunoda kuwedzera sodium acetate senge kabhoni sosi kuti isangane neiyo yekutanga-level emission standard.

Sodium sulfate zvigadzirwa zvakakamurwa kuita yakasimba uye mvura mhando mbiri, yakasimba sodium acetate C2H3NaO2 yemukati ≥58-60%, chitarisiko: isina ruvara kana chena yakajeka kristaro. Liquid sodium acetate content: content ≥20%, 25%, 30%. Chitarisiko: Mvura yakajeka uye yakajeka. Sensory: hapana kunhuhwirira kunhuhwirira, mvura isingagadzirike nyaya: 0.006% kana zvishoma.
Chikumbiro: Sodium acetate inoshandiswa seyekuwedzera kabhoni sosi mumiti yekuchenesa tsvina kuti iwedzere denitrification sludge, iyo inogona kuwana yakakwira chaiyo denitrification mwero. Parizvino, ese emasuweji emasuweji kana maindasitiri etsvina yekuchenesa kuti asangane nedanho rekubuda A chiyero chinoda kuwedzerwa kwesodium acetate senge kabhoni sosi.
1. Inonyanya kuita basa rekugadzirisa kukosha kwePH yetsvina. Inogona hydrolyze mumvura kuti iite OH-negative ions, iyo inogona kuderedza acidic ions mumvura, yakadai seH +, NH4 + nezvimwe zvakadaro. Iyo hydrolysis equation ndeye: CH3COO-+H2O= inodzoserwa =CH3COOH+OH-.
2. Sekuwedzera kabhoni sosi, buffer solution inoshandiswa kudzora kukwira kwepH kukosha mukati me0.5 mukuita denitrification. Mabhakitiriya eDenitrifying anogona kunyudza CH3COONa, saka kukosha kweCOD kwetsvina kunogona kuchengetedzwa padanho rakaderera kana CH3COONA ichishandiswa seimwe kabhoni sosi ye denitrification. Kuvapo kwesodium acetate ikozvino kunotsiva iyo yapfuura kabhoni sosi, uye sludge yemvura inowedzera kushanda mushure mekushandisa.
3. Inoita basa rinokosha mukugadzikana kwehutano hwemvura. Mune tsvina ye nitrite uye phosphorus, inogona kushandiswa pakugadzirisa mhedzisiro, iyo inogona kuvandudza kusimba kwekuora kwekudzivirira. Kana bvunzo ikaitwa pane dzakasiyana masosi emvura, shoma shoma yeindasitiri giredhi sodium acetate inogona kushandiswa kutanga kuwana iyo yakakodzera dosi. Kazhinji, maitiro ekugadzira bhizinesi achange ari akasimba uye emvura chiyero che1 kusvika ku5, kupedzisa hurongwa hwekunyungudika usati wawedzera mvura yekunatsa.
