Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, in particular to palladium-containing wastewater treatment equipment in a preparation process of fenpyrotone. Background Art

[0002] Benzopyrazone is the first benzoyl pyrazolone-type cornfield post-emergence herbicide developed by BASF. It is a para-hydroxyphenylpyruvate dioxidase inhibitor. It has been on the market since 2011. The product name for the domestic market is "Baowei", which breaks the safety defects of conventional cornfield herbicides during use and has attracted the attention of industry insiders. The safety of benzathine is the most prominent advantage for corn and subsequent crops. It is widely used in almost all corn varieties such as ordinary corn, glutinous corn, sweet corn, seed corn, popcorn, etc. At the same time, it has a wide spectrum of weed control, high activity, and strong miscibility. It has a good control effect on weeds resistant to glyphosate, triazines, acetolactate synthase inhibitors and acetyl-CoA carboxylase inhibitors. In the preparation process of benzathine, a large amount of palladium-containing wastewater will be generated. It is often necessary to filter the palladium-containing wastewater and remove the palladium-containing waste before it can be discharged into the external environment. If it is discharged at will, it will cause environmental pollution. Therefore, it is necessary to treat the palladium-containing wastewater harmlessly.

[0003] Most of the existing palladium-containing wastewater treatment equipment used in the preparation process of fenpyrazone cannot filter out the palladium-containing impurities in the palladium-containing wastewater and collect the palladium-containing waste well. The palladium-containing waste does have a high economic value, so its effective recycling is very beneficial to reducing production costs. In addition, most of the existing palladium-containing wastewater treatment equipment used in the preparation process of fenpyrazone has an imperfect filtering effect on the palladium-containing waste, and the palladium-containing wastewater that has not been filtered is often discharged to the outside, which will cause the palladium-containing wastewater to pollute the environment, affect the local ecological environment, and cause the staff inside the factory to have abnormal health due to contact with the palladium-containing wastewater.
