Description

Technical Field

[0001] The utility model relates to the technical field of tea processing, in particular to a tea processing wastewater treatment device. Background Art

[0002] Tea processing is to change the original form of tea through membrane concentration, vacuum freeze drying, ultra-fine grinding and other technologies, so that the finished product is no longer a "leaf" shaped solid, that is, the physical processing of tea. Wastewater is generated during the tea processing process. The wastewater contains tea polyphenols, caffeine, water-soluble vitamins, sugars, minerals, amino acids, etc., which need to be treated, so tea processing wastewater treatment equipment is needed;
