Nickel-containing wastewater filtration system in production process of aminophenazone

Abstract

The invention provides a nickel-containing wastewater filtration system in the production process of aminophenazone. The filtration system includes a washing tower, a first-level sedimentation tank, afiltration liquid storage tank, an infusion pump and a PM filter. Washing water which contains an activated Ni catalyst is introduced from the washing tower into the first-level sedimentation tank, the obtained water overflows through an overflow pipeline of the first-level sedimentation tank into the filtration liquid storage tank after sedimentation is performed, and the obtained clear liquid is discharged outside after filtration is performed, so that nickel-containing wastewater is filtered automatically, the cleaning frequency is increased, regularization of cleaning is achieved, and itis ensured that residues at the bottom layer of the sedimentation tank can be discharged more easily than before; and secondary sedimentation tanks are not used any more, so that the labor operation of employees is reduced.

Description

technical field [0001] The invention belongs to the field of medicine and chemical industry, in particular to a filtration system for nickel-containing waste water in the production process of aminopyrine. Background technique [0002] Aminophenazone chemical name is 1-phenyl-2,3-dimethyl-4-dimethylaminopyrazolone, white or almost white crystalline powder; odorless, slightly bitter taste; Deterioration; aqueous solution shows alkaline reaction. This product is soluble in ethanol or chloroform, soluble in water or ether. The molecular formula is C13H17N3O, and the molecular weight is 231.29. [0003] Aminopyrine is a pyrazolone antipyretic, analgesic and anti-inflammatory drug, which can inhibit the synthesis and release of prostaglandin E1 in the neurons of the anterior hypothalamus, restore the normal reactivity of sensory neurons in the temperature regulation center and play an antipyretic effect; Aminopyrine can also inhibit the synthesis and release of prostaglandins ...

AI Technical Summary

Problems solved by technology

[0007] (1) The settling time of the settling tank is difficult to guarantee

According to the production task, the amount of washing water is sometimes large. In this case, the settling time of the settling tank is often short, which will lead to incomplete settlement of Ni entering the washing water, increase the pressure of subsequent treatment, and even cause the Ni content of the di
