Abstract

The invention provides a device for harmless and resourceful treatment of fungi residue and waste water of erythromycin and an integration process. The purposes of harmless treatment of waste water ofthe fungi residue and resourceful treatment of the fungi residue of the erythromycin are achieved by adopting physical-chemical integration process technology to treat the fungi residue and the wastewater of the erythromycin. The treatment process comprises the following steps: coagulation / flocculation, solid-liquid separation, catalytic hydrothermal carbonization, activation of carbonized fungiresidue and purification of the waste water in the carbonized and activated fungi residue. The device and the integration process provided by the invention have the beneficial effects that the carbonized fungi residue is prepared into an adsorbing material by activation reaction, and then the adsorbing material is used for purifying treatment of the fungi residue and the waste water, so that theresourceful and harmless treatment of the fungi residue is realized; the erythromycin degradation rate is more than 90% and the residual valence is less than 30.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment in the fermentation pharmaceutical (antibiotic) industry, and relates to a harmless and resourceful treatment device and an integrated process for erythromycin residue wastewater. Background technique [0002] my country is the world's largest producer and exporter of antibiotic raw materials. There are more than 70 kinds of antibiotics produced every year, with an annual output of about 248,000 tons, accounting for 70% of the world's total. Among them, the annual production capacity of erythromycin is more than 10,000 tons. More than 6000 tons. Assuming that 1 ton of antibiotics produces 10 tons of bacterial residue, 2 million tons of bacterial residue will be produced every year. The moisture content of fresh fungus residue is as high as 90%, which is easy to deteriorate and stink. If it cannot be disposed of in a timely and effective manner, it will cause air, water and soil envir...
