Embodiment 1
[0011] Implementation example one: get 1000g of lacquer-containing wastewater, add 0.1g of sodium hydroxide, and fully stir and dissolve the melamine polymer 0.1g / L; then get 0.2g of the additive, add it to the wastewater, fully stir and dissolve; then take polyacrylamide 0.001g ( Polyacrylamide needs to be pre-prepared into a 0.3% aqueous solution before adding), add it to the paint-containing wastewater, and fully stir; the paint-containing wastewater treated with the paint mist coagulant has clear water quality and no peculiar smell. The floating rate of paint slag is high and the viscosity is completely removed.
Embodiment 2
[0012] Implementation example two: get 1000g of lacquer-containing wastewater, add 0.5g of sodium hydroxide, and fully stir and dissolve melamine polymer 0.1g / L; then add 0.03g of isothiazolinone, fully stir and dissolve; get additive 0.4g, add in the wastewater, Fully stir to dissolve; take 0.005g of polyacrylamide (pre-prepared into 0.3% aqueous solution before adding the polyacrylamide), add it to the paint-containing wastewater, and fully stir. The paint-containing wastewater treated by the paint mist coagulant has clear water quality and no peculiar smell. The floating rate of paint slag is high and the viscosity is completely removed.
Embodiment 3
[0013] Implementation example three: get 1000g of lacquer-containing wastewater, add sodium hydroxide 0.8g melamine polymer 0.1g / L, fully stir and dissolve; then add isothiazolinone 0.06g, fully stir and dissolve; get additive 0.6g, add in the wastewater, Thoroughly stir to dissolve; take 0.01g of polyacrylamide (pre-prepared as 0.3% aqueous solution before adding polyacrylamide), add it into the paint-containing wastewater, and stir thoroughly. The paint-containing wastewater treated by the paint mist coagulant has clear water quality and no peculiar smell. The floating rate of paint slag is high and the viscosity is completely removed.
