Abstract

The invention discloses a recycling device for treating wastewater produced during extraction of stevioside from stevia rebaudiana and relates to the technical field of wastewater treatment. The device comprises a box, a first partition board and a second partition board are fixedly connected in the box, the bottom of the first partition board is rotationally connected with a rotating shaft, the surface of the rotating shaft is fixedly connected with a first bevel gear, propelling blades and rotating blades from top to bottom, leaking holes are formed in surfaces of the rotating blades, and the back side of the box is fixedly connected with a rotating motor through a motor cavity. According to the recycling device and method for treating wastewater produced during extraction of steviosidefrom stevia rebaudiana, the rotating shaft drives the propelling blades to rotate to propel wastewater to flow, the rotating blades rotate continuously to push impurities adsorbed on a first filter net into a sediment collecting box, blockage of the first filter net by the impurities is prevented, the impurities are collected and centralized for treatment while blockage is prevented, the wastewater can be filtered quickly, and the service life of the wastewater filter device is prolonged.

Description

technical field [0001] The invention relates to the technical field of waste water treatment, in particular to a waste water treatment recycling device and method for extracting stevioside with stevia rebaudiana. Background technique [0002] Stevia is a perennial herb of the Asteraceae and Stevia genus. The main component of stevia dry leaves is steviol glycoside, which not only has high sweetness and low calorie, but also has certain pharmacological effects. Stevia glycosides are mainly used to treat diabetes and control blood sugar. , lower blood pressure, anti-tumor, anti-diarrhea, improve immunity, promote metabolism, etc. It has a good effect on controlling obesity, regulating gastric acid, and recovering from nervous fatigue. It also has significant effects on heart disease and dental caries in children. The most important It can eliminate the side effects of sucrose. Stevia leaf residue is rich in trace elements and comprehensive in nutrients, such as amino acids, cr...
