Comprehensive erythromycin thiocyanate mushroom dreg waste water disposal system and method

Abstract

The invention discloses a comprehensive erythromycin thiocyanate mushroom dreg waste water disposal system which comprises a pretreatment unit, a hydrolytic acidification unit, an anaerobic treatment unit and an aerobic treatment unit, which are connected in sequence, wherein the pretreatment unit comprises a regulating tank, the water inlet of the regulating tank is communicated with a water-collecting well for collecting the mushroom dreg waste water, the hydrolytic acidification unit comprises a hydrolytic acidification tank, the anaerobic treatment unit is a high-efficiency anaerobic reactor, the aerobic treatment unit comprises a first-class contact oxidation tank and a second-class contact oxidation tank which are connected in series, the first-class contact oxidation tank is connected with the second-class contact oxidation tank sequentially via a medium sedimentation tank and a Fenton reaction tank, the second-class contact oxidation tank is connected with a secondary sedimentation tank, the secondary sedimentation tank is provided with two outlets, the two outlets are communicated with a liquid supernatant pipeline and a sludge thickener respectively, and the bottom of the medium sedimentation tank is communicated with the sludge thickener. The treatment method disclosed by the invention is low in energy consumption and investment, high in efficiency and steady and reliable in treatment effect.

Description

technical field [0001] The invention relates to a comprehensive treatment system and method for erythromycin thiocyanate bacteria residue wastewater. Background technique [0002] At present, the country prohibits antibiotic residues from being used as animal feed and lists them as hazardous waste. Antibiotic residues have become an important factor restricting the development of enterprises. Therefore, comprehensive development of antibiotic residues is an urgent need for enterprises to achieve sustainable development. [0003] Antibiotic mycelium waste is the waste produced by antibiotic production enterprises in the process of producing antibiotics. Our country's antibiotic by-product fungus slag reaches more than 1.8 million tons per year. Due to its rich nutrition, the average crude protein content is more than 40%, and the content of various essential amino acids, vitamins and trace elements is rich and balanced. It is an excellent raw material for comprehensive biolog...
