Embodiment 1
[0042] The present embodiment carries out the simultaneous treatment of acetylacetone wastewater and metal ion wastewater through the following steps:
[0043] 1. The mixed reaction of acetylacetone wastewater and metal ion wastewater prepares chromium acetylacetonate solution:
[0044] The simulated acetylacetone wastewater used in this example contains 5 g / L of acetylacetone, the simulated metal ion wastewater is simulated chromium ion wastewater, and the concentration of chromium ions is 13.32 g / L.
[0045] Wherein the simulated acetylacetone wastewater is prepared as follows: take 400mL of 95% ethanol, then add 4.1mL of 99% acetylacetone to it, and stir for 5 minutes, so that the acetylacetone, ethanol and deionized water are completely mixed to obtain the acetylacetone simulated wastewater.
[0046] The simulated chromium ion wastewater was prepared as follows: take 10.656g of chromium chloride in 400ml deionized water, stir for 5 minutes to completely dissolve the chromi...
Embodiment 2
[0062] The present embodiment carries out the simultaneous treatment of acetylacetone wastewater and metal ion wastewater through the following steps:
[0063] 1. The mixed reaction of acetylacetone wastewater and metal ion wastewater prepares chromium acetylacetonate solution:
[0064] The simulated acetylacetone wastewater used in this example contains 10 g / L of acetylacetone, and the simulated metal ion wastewater is chromium ion wastewater, wherein the concentration of chromium ions is 13.32 g / L.
[0065] Wherein the simulated acetylacetone wastewater is prepared as follows: take 400mL of 95% ethanol, then add 8.2mL of 99% acetylacetone to it, and stir for 5 minutes, so that the acetylacetone, ethanol and deionized water are completely mixed to obtain the acetylacetone simulated wastewater.
[0066] The simulated chromium ion wastewater was prepared as follows: take 10.656g of chromium chloride in 400ml deionized water, stir for 5 minutes to completely dissolve the chromiu...
Embodiment 3
[0081] The mixed reaction of acetylacetone wastewater and metal ion wastewater prepares chromium acetylacetonate mixed solution:
[0082] The simulated acetylacetone wastewater used in this example contains 15 g / L of acetylacetone, and the simulated metal ion wastewater is chromium ion wastewater, wherein the concentration of chromium ions is 13.32 g / L.
[0083] Wherein the simulated acetylacetone wastewater was prepared as follows: 400mL of 95% ethanol was taken, then 12.3mL of 99% acetylacetone was added thereto, and stirred for 5 minutes, so that the acetylacetone, ethanol and deionized water were mixed completely to obtain the acetylacetone simulated wastewater.
[0084] The simulated chromium ion wastewater was prepared as follows: take 10.656g of chromium chloride in 400ml deionized water, stir for 5 minutes to completely dissolve the chromium chloride, and obtain simulated chromium ion wastewater.
[0085] In this embodiment, chromium ion and acetylacetone are complexed...
