Embodiment Construction

[0018] The invention is further explained below.

[0019] COD is the abbreviation of ChemicalOxygenDemand, which refers to chemical oxygen demand. It refers to the amount of oxidant consumed when treating water samples with strong oxidants. It is an index indicating the amount of reducing substances in water. The reducing substances in water mainly refer to organic matter. Therefore, COD is an indicator to measure the content of organic matter in water. NH3-N is an indicator of ammonia nitrogen content in wastewater. Total P refers to the phosphorus content index in wastewater.

[0020] The waste water produced by fluroxypyr during the production process contains more substances such as glyphosate, bisglyphosate, formaldehyde, formic acid, potassium fluoride, sulfolane, etc. The following is an example to illustrate the method of treating the pesticide waste water:

[0021] (1) Pass the pesticide wastewater through the multi-effect distiller. Generally, the COD value of the ...

Abstract

The invention discloses a technique for treating pesticide wastewater containing phosphorus. The technique for treating the pesticide wastewater containing the phosphorus comprises the technical processes of multiple-effect evaporation, neutralization, flocculent setting, biological treatment, advanced oxidation of ozone and the like, novel densely-supporting padding is arranged in the biological process, and thus the treatment effect at the biological stage is improved. According to the technology, glyphosate mother liquor wastewater, mother liquor from amination and condensed washing secondary wastewater are mixed to treat waste and reduce the load of all organic pollutants in the wastewater. The B / C ratio of the wastewater difficult to degrade is increased, the technique is safe and advanced, operation is stable, operating cost is low, and maintenance is easy.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a process for treating phosphorus-containing pesticide wastewater. Background technique [0002] Fluroxypyr is a systemic conduction type postemergence herbicide. This product is applicable to a variety of crops and has a wide herbicidal spectrum. In drug-resistant plants such as wheat, fluroxypyr can be combined into conjugates to lose toxicity, so it is selective. It is currently the best dry field weed control in the world one of the agents. The wastewater generated during the production of fluroxypyr contains a lot of glyphosate, bisglyphosate, formaldehyde, formic acid, potassium fluoride, sulfolane and other substances. The wastewater treatment is difficult, and there is no mature and effective industrialization at home and abroad. Governance method. This wastewater contains many toxic and harmful pollutants. The values ​​of COD and NH3-N in the system are high, t...
