Embodiment 1

[0028] see figure 1 , the embodiment of the present invention is solely directed at the treatment of benzohydroxamic acid production wastewater, provides a kind of ozone iron carbon micro-electrolysis process benzohydroxamic acid production wastewater process, specifically comprises the following steps:

[0029] S01, pass ozone to the benzohydroxamic acid production wastewater, and continue to carry out the ozone reaction;

[0030] S02. Add hydrogen peroxide and iron-carbon mixed reagent, stir evenly, and continue the iron-carbon micro-electrolysis reaction;

[0031] S03, add calcium hydroxide solution to adjust the pH value, and then continue to aerate;

[0032] S04, set aside to settle, so that ferrous hydroxide and ferric hydroxide obtained from the iron-carbon micro-electrolysis reaction are precipitated.

[0033] The technical feature of the present invention is that it adopts a joint treatment process of ozone first and then iron-carbon micro-electrolysis. Its process...

Abstract

The invention provides a process for treating benzohydroxamic acid production wastewater by ozone iron-carbon micro-electrolysis, which comprises the following steps: S01, introducing ozone into benzohydroxamic acid production wastewater, and continuously carrying out ozone reaction; s02, adding hydrogen peroxide and an iron-carbon mixed reagent, uniformly stirring, and continuously carrying out iron-carbon micro-electrolysis reaction; s03, adding a calcium hydroxide solution to adjust the pH value, and then continuously aerating; and S04, standing and settling are conducted, and ferrous hydroxide and ferric hydroxide obtained through the iron-carbon micro-electrolysis reaction are precipitated. Efficient wastewater treatment is completed through ozone and iron-carbon micro-electrolysis reaction and optimal test data research.

Description

technical field [0001] The invention relates to the field of water treatment technology, in particular to an ozone iron-carbon micro-electrolysis process for treating wastewater produced by benzohydroxamic acid. Background technique [0002] Water environmental pollution poses great challenges to water treatment and poses a great threat to the safe water supply of cities. With the development and progress of the economy and society, the demand for mineral products in industrial production continues to expand, leading to the vigorous development of the mining industry. Among them, benzohydroxamic acid is a commonly used mineral dressing agent, which is a refractory organic substance. [0003] Benzohydroxamic acid production wastewater is a kind of organic wastewater with strong acidity, pungent smell and high COD content. Directly discharged into the natural environment, it will accumulate in water, soil and other environments, thereby causing water and soil pollution. After...
