1.Dosage ye reagent (PPM) = [(kudonha nhamba /20) × dilution concentration / volume ye test wastewater] ×106
★ PPM chikamu chimwe pamiriyoni, uye muyero i1PPM, iyo yakaenzana ne 1 toni yemvura yakasviba, chiyero chemumiririri i1 gram.
★ 1ML diluted solution yakaenzana nemadonhwe makumi maviri
2.Shandisa beaker kutora 200ML ye test wastewater (chroma 200, COD 110), gadzirisa kukosha kwePH kusvika pa8, wedzera madonhwe gumi edecolorizing agentmhinduro ine eyedropper (1ML yakaenzana nemadonhwe makumi maviri), kurunga, wobva wawedzera madonhwe gumi nemaviri ePAC, kurunga, uye pakupedzisira wedzera madonhwe maviri ePAM, kurunga, uye kumira kweminiti imwe. Iyo yekuongorora chroma ndeye 4 (dilution yakawanda nzira) uye COD i85, inosangana neyakajairwa emission standard.
3. Chiyero chekugadzirira reagent:decolorizing agent(2% mhinduro, kureva, dilution ka50), PAC (2% mhinduro), PAM (1 ‰ aqueous solution)
Huwandu hwedecolorizing agent= [(10/20) ×2%/200] ×106 = 50PPM
PAC chipimo chemushonga = [(12/20) ×2%/200] ×106 = 60PPM
Nhamba yePAM = [(2/20) ×1‰/200] ×106 = 0.5PPM
Huwandu hwedecolorizing agentiri 50PPM, iyo yakaenzana ne50 gramu yedecolorizing agentstock solution mune imwe toni yemvura yakasviba, zvichingodaro, PAC i60 magiramu, uye PAM i0.5 magiramu.
