Description

Technical Field

[0001] The present application relates to the field of water treatment technology, and in particular to a berberine pharmaceutical wastewater treatment system. Background Art

[0002] Berberine, also known as berberine hydrochloride, is a yellow or white crystalline powder with an extremely bitter taste. It is a natural isoquinoline alkaloid antibiotic with multiple biological activities and pharmacological effects. It is mainly used to treat gastroenteritis, bacterial dysentery and other intestinal infections, conjunctivitis, suppurative otitis media, etc. It inhibits various Gram-positive and Gram-negative bacteria such as hemolytic Streptococcus, Vibrio cholerae, Staphylococcus aureus, and meningococci to achieve the effect of inhibition at low concentrations and bactericidal at high concentrations.

[0003] In related technologies, berberine is mainly produced through natural plant extraction and chemical synthesis. The chemical synthesis method requires washing the finished product during production, generating a large amount of wastewater (such as berberine copper-containing wastewater and berberine mother liquor wastewater), which is berberine pharmaceutical wastewater.

[0004] Berberine pharmaceutical wastewater is a typical antibiotic wastewater, which contains high concentrations of berberine, copper ions and dichromate index (COD Cr ) is high. Since berberine pharmaceutical wastewater contains a high concentration of berberine, it has a strong antibacterial effect and strong microbial toxicity to the wastewater, which leads to great difficulties in aerobic treatment and anaerobic treatment. It has poor biodegradability and it is difficult to effectively treat berberine pharmaceutical wastewater by conventional biochemical treatment. Utility Model Content
