Traditional Chinese medicine wastewater treatment system and method for treating traditional Chinese medicine wastewater

Abstract

The invention discloses a traditional Chinese medicine wastewater treatment system and a method for treating the traditional Chinese medicine wastewater. The traditional Chinese medicine wastewater treatment system comprises four parts: a pretreatment system, a biochemical treatment system, an advanced treatment system and a sludge treatment system. Wastewater storage tank, three-dimensional electrolytic tank, sand filter tank, secondary filter tank, and aeration device mainly play the role of blowing off in the treatment system, remove chloroform in wastewater, enable microorganisms in subsequent treatment structures to survive, and solve the difficult problem of traditional Chinese medicine wastewater Biochemical disadvantages; the present invention uses three-dimensional electrolysis in wastewater treatment, and the electrolysis wastewater can degrade 80% of the COD in wastewater after 24 hours of testing, and the effect on treating difficult organic wastewater is obvious, increasing the biodegradability of wastewater; The invention combines coagulation sedimentation filtration, blowing off, three-dimensional electrolysis, and biochemical treatment, resulting in clear effluent quality and low process cost.

Description

technical field [0001] The invention relates to a new wastewater treatment process, in particular to a traditional Chinese medicine wastewater treatment system and a method for treating traditional Chinese medicine wastewater. Background technique [0002] Traditional Chinese medicine wastewater pollution is mainly high-concentration organic wastewater, which comes from the production workshop and is produced during the process of washing and cooking medicinal materials, washing, and preparation. Wastewater includes raw drug washing wastewater in the production process, raw drug juice residue, filtration, distillation, extraction and other units of waste water. The main components of traditional Chinese medicine wastewater are sugar, ethanol, chloroform, glycosides, anthraquinone, lignin, alkaloid, tannin, protein, pigment and other substances. The concentration of organic pollutants is quite high, and the suspended solids such as lignin have a light specific gravity. , hi...

AI Technical Summary

Problems solved by technology

1) The wastewater pretreatment function is not good enough. Many traditional Chinese medicine wastewater contains organic solvents such as chloroform and ethanol. When the chloroform content in the wastewater is 0.5mg / L, the microorganisms will be dormant, making it difficult to carry out biological treatment, resulting in subsequent treatment The unit is difficult to operate; 2) The concentration of pollutants in traditional Chinese medicine wastewater is high, the specific gravity of suspended solids is light, it is difficult to settle, and the biodegradability of wastewater is poor. ,higher cost
