Kev suav ntawm decolorizing tus neeg saib xyuas ntau npaum li cas (kev xeem tshwj xeeb ua piv txwv)

1.Dosage of reagent (PPM) = [(poob naj npawb /20) × dilution concentration/volume of test wastewater] × 106

★ PPM yog ib feem ntawm ib lab, thiab qhov ntau npaum li cas yog 1PPM, uas yog sib npaug rau 1 tuj dej khib nyiab, qhov ntau npaum li cas ntawm tus neeg sawv cev yog 1 gram.

★ 1ML diluted tov yog sib npaug rau 20 tee

2.Siv lub beaker coj 200ML ntawm cov dej khib nyiab (chroma 200, COD 110), kho tus nqi PH rau 8, ntxiv 10 tee ntawmdecolorizing tus neeg sawv cevtov nrog ib tug eyedropper (1ML yog sib npaug rau 20 tee), do, ces ntxiv 12 tee ntawm PAC, do, thiab thaum kawg ntxiv 2 tee ntawm PAM, do, thiab sawv ntsug rau ib feeb. Kev kuaj pom chroma yog 4 (dilution ntau txoj kev) thiab COD yog 85, uas ua tau raws li lub teb chaws emission standard.

3. Qhov ntau npaum li cas ntawm reagent npaj:decolorizing tus neeg sawv cev(2% tov, uas yog, dilution 50 zaug), PAC (2% tov), ​​PAM (1‰ aqueous tov)

Tus nqi ntawmdecolorizing tus neeg sawv cev= [(10/20) × 2% / 200] × 106 = 50PPM

PAC ntau npaum li cas = [(12/20) × 2% / 200] × 106 = 60PPM

PAM = [(2/20) × 1‰/200] × 106 = 0.5PPM

Tus nqi ntawmdecolorizing tus neeg sawv cevyog 50PPM, uas yog sib npaug rau 50 grams ntawm covdecolorizing tus neeg sawv cevCov tshuaj hauv ib tuj ntawm cov dej khib nyiab, thiab lwm yam, PAC yog 60 grams, thiab PAM yog 0.5 grams.
