Abstract

The invention discloses a system for treating wastewater in the production of ammonium paratungstate. The system comprises an acidic waste liquid collection groove, wherein a liquid outlet of the acidic waste liquid collection groove is connected with a feeding hole of an ion exchange column; a discharging hole of the ion exchange column is connected with a feeding hole of a reaction kettle; the inner wall of the reaction kettle is lined with a corrosion-resisting graphite layer and a PP (Polypropylene) layer in sequence from inside to outside; a stirring device and a heating device are arranged in the reaction kettle; a filtering device is further arranged at the downstream position of the reaction kettle; the filtering device is used for filtering and discharging calcium superphosphate; and when the reaction kettle works, the stirring temperature of 50 DEG C to 70 DEG C is kept in the reaction kettle. The system disclosed by the invention can be used for carrying out a series of treatment on acidic waste liquid to form calcium superphosphate and calcium superphosphate is convenient to recycle.

Description

Technical field [0001] The invention relates to the field of ammonium paratungstate production equipment, in particular to an ammonium paratungstate production wastewater treatment system. Background technique [0002] Ammonium paratungstate (APT) is an important intermediate compound in the production of tungsten powder, tungsten wire, tungsten-based alloys and all tungsten materials, and it is also my country's bulk export commodity. During the production of ammonium paratungstate, a large amount of acidic waste liquid is produced. For these acidic waste liquids, there is currently no effective treatment method or equipment. Summary of the invention [0003] The purpose of the present invention is to provide a wastewater treatment system for the production of ammonium paratungstate in view of the above-mentioned shortcomings and defects of the prior art to solve the above-mentioned problems. [0004] The technical problem solved by the present invention can be realized by the fol...
