Sea sponge filter, sponge filter uses German source water (certified merchants)

The effect of pH on the treatment effect of soy sauce wastewater 100 mL, in the dosage of wastewater concentration and the same conditions sponge filter sponge, sponge iron particle size 0.5 ~ 1.0 mm, the dosage of 20 g of oxygen sponge iron filter, sponge filter oscillation time 60 min instructions to adjust the pH value of the sponge filter with 3% oxygen H2SO4,4% of NaOH and phenolphthalein solution, investigated the effect of different pH on wastewater treatment efficiency. Sponge amount of static experiments 100mL simulated dyeing wastewater of different colors (formulated by different colors such as red, acid yellow, acidic dark blue, light black, dye made) in a conical flask, add the amount of sponge iron at room temperature with 140r / min speed oscillation period of time, standing, and the supernatant measured by its color dilution method to calculate the decolorization rate.
