Abstract

The invention provides a device and a method for degrading macrolide antibiotics in pharmaceutical wastewater, and applications of the method. According to the device, a side wall preheating device isarranged in the side wall of a preheating tank body; one end of a central preheating device is mounted in the middle of the bottom end of the preheating tank body; a temperature sensor is fixed on the inner wall of the preheating tank body; a feeding hole is formed in the top end of a reaction kettle body, and is communicated with the preheating discharge hole of the preheating tank through a feeding pipeline; a feeding valve is arranged on the feeding pipeline; a discharge hole is formed in one side of the bottom end of the reaction kettle body; a scraping device is arranged on one side, faraway from the discharge hole, of the bottom end of the reaction kettle body; a stirring device is arranged at the top end of the reaction kettle body; the discharge hole is communicated with the centrifugal feeding port of a centrifugal separator through a discharging pipeline; a centrifugal separation motor is installed at the top end of the centrifugal separator; the centrifugal separator is installed in a separation tank; and a liquid-state product discharging port is formed in the bottom of the separation tank. The hydrothermal carbonization technology has good degradation performance onmacrolide antibiotics.

Description

technical field [0001] The invention relates to the technical field of antibiotic degradation devices, in particular to a device for degrading macrolide antibiotics in pharmaceutical wastewater, a method and application thereof. Background technique [0002] Antibiotics are a class of drugs that are widely used in China at present, and are generally produced by microorganisms during their metabolism. It is worth noting that the fermentation pharmaceutical wastewater left after antibiotic extraction has complex components and contains a large amount of fermentation residue. The water content in it is relatively high, and most of it is intracellular water, which is difficult to remove mechanically. The organic components of the nutrient matrix are highly perishable, releasing foul-smelling gases. Even, the residues contain some antibiotic drug residues, drug intermediates and organic solvents, etc., which are biologically toxic and will cause long-term potential harm to the e...
