[0032] 1 Determination of orthophosphate in bottom pot water
[0033] 1.1 Reagents and materials
[0034] 1.1.1 Sulfuric acid (H 2 SO 4 ), the density is 1.84g / mL.
[0035] 1.1.2 Ascorbic acid, 100g / L solution.
[0036] 1.1.3 Molybdate solution: Dissolve 13g of ammonium molybdate in 100mL of water. Dissolve 0.35g antimony potassium tartrate in 100mL water. Slowly add the ammonium molybdate solution to 300mL of sulfuric acid (mixture of concentrated sulfuric acid with a mass concentration of 98% and water at a ratio of 1:1 by volume) under constant stirring, then add antimony potassium tartrate solution and mix well.

The invention discloses a method for rapidly measuring the total phosphorus of white wine industrial wastewater (bottom pot water). According to the method, visual colorimetry is adopted; after a bottom pot water sample is diluted, a reaction reagent is added to the diluted bottom pot water sample; the color development of the diluted bottom pot water sample is compared with a colorimetric plate with known total phosphorus concentration gradients, and therefore, the concentration of the diluted bottom pot water sample can be judged; the concentration of the diluted bottom pot water sample is multiplied by a dilution factor, so that the concentration of orthophosphate can be obtained; and the concentration of total phosphorus is inferred based on the concentration of the orthophosphate. With the method adopted, the total phosphorus of the white wine industrial wastewater (bottom pot water) can be quickly and quantitatively determined, working efficiency is improved, timely and effectivetechnical support can be provided for production process adjustment, the standard discharge of the total phosphorus concentration of externally discharged water is ensured, resources can be saved, and the environment can be protected.
Description
technical field [0001] The invention relates to a method for rapidly determining the total phosphorus in liquor industrial wastewater-bottom pot water, belonging to the field of determination methods for total phosphorus in wastewater. Background technique [0002] Phosphorus is one of the elements necessary for the growth of organisms. However, if the phosphorus content in the water is too high, it can cause the excessive reproduction of algae until eutrophication, resulting in the decrease of the transparency of lakes and rivers and the deterioration of water quality. Therefore, the determination of total phosphorus in water is very necessary. Total phosphorus is also one of the national discharge indicators. It is required that the external drainage must meet the national drainage standards. Therefore, the content of total phosphorus in the water quality at each stage must be strictly controlled to ensure that the external drainage meets the discharge standards. Therefor...
