Problems solved by technology

The use of physical methods, chemical methods, etc. to treat wastewater containing nitrobenzene compounds has the problem of secondary pollution or high treatment costs. Wastewater containing nitrobenzene compounds generally has high toxicity, so that the cultivation of sludge in biological treatment It is more difficult and time-consuming to domesticate, and nitrobenzene-containing compounds are difficult to biochemically degrade, and the biochemical methods commonly used to treat organic pollutants are also severely restricted

Abstract

The invention relates to a water treatment agent for removing nitrobenzene compounds in water. The water treatment agent is compounded by 6,6,10-trimethyl bicyclo-3,1,1-heptyl-2-ene, 3-phenyl-2-propylester, rabeprazole sodium, ferric ammonium oxalate, alpha-copaene, dipyrazolone, buflomedil, 2-(4-methyl-3-cyclohexenyl)-2-propanol, ferric chloride, asiaticoside, silymarin, 3-nonylene-2-ketone, polyacrylamide, gluconic acid lactone, benidipine hydrochloride and 2-hydroxyethyl cellulose. The water treatment agent has strong complexing capacity for the nitrobenzene compounds, the precipitation speed of complexes is high, the removal rate can reach 99%, toxicity is low, the dosage is low, no harm is caused to water, and treatment cost is low.

Description

technical field [0001] The invention relates to a water treatment agent for removing nitrobenzene compounds in water, belonging to the technical field of environmental protection. Background technique [0002] As important chemical raw materials, nitrobenzene compounds are widely used in pharmaceutical, chemical, dye and other industries. This type of compound is extremely toxic to human body and microorganisms, and its chemical properties are stable. The benzene ring is prone to electrophilic substitution, but it is not easy to undergo oxidation reaction. Therefore, in general, oxygen is used to break the aromatic ring to achieve nitrobenzene compounds Molecular cleavage is not easy. my country lists nitrobenzene, p-nitrotoluene, 2,4-dinitrotoluene, trinitrotoluene, p-nitrochlorobenzene, and 2,4-dinitrochlorobenzene as priority control nitrobenzene pollution thing. [0003] At present, the treatment methods of p-nitrobenzene compounds mainly include physical methods (st...
