The invention relates to a process for producing basic
copper chloride by using
berberine copper-containing
wastewater. The method comprises the steps that:
berberine copper-containing
wastewater is filtered by using a microporous membrane; 90-110g / L of a
sodium hydroxide concentrated solution is added into the
berberine copper-containing
wastewater; a reaction is carried out under a temperature of 60-80 DEG C, a pH of 5-7, and a normal pressure, such that basic
copper chloride precipitate is produced; after the reaction, the produced precipitate is first subjected to
centrifugal separation; obtained
solid is washed and subjected to washing and
centrifugal separation; and the
reaction product basic
copper chloride is obtained after
drying; centrifuged supernatant is subjected to two-level absorption, and is treated in a biochemical treatment device. According to the invention, basic
copper chloride is prepared from berberine pharmaceutical wastewater containing
high concentration of heavy
metal copper, such that the treatment difficulty of the
medicine pharmaceutical wastewater which is hard to degrade is reduced. The process provided by the invention is characterized in that: a copper
ion removal rate in the berberine copper-containing wastewater is higher than 99.9%, such that high-concentration hard-to-degrade pharmaceutical wastewater is turned into organic wastewater which can be biodegraded. After biochemical treatment, the wastewater reaches a
discharge standard. The process has the advantages of good
treatment effect, convenient operation, and good application prospect.
