Problems solved by technology

[0003] Erythromycin membrane slurry is erythromycin fermentation broth, in which the residual antibiotics and high-concentration organic matter are difficult to achieve the expected treatment effect by traditional biological treatment, because the strong inhibitory effect of residual antibiotics on microorganisms poisons aerobic bacteria, causing good Oxygen treatment is difficult; and anaerobic treatment of high-concentration organic matter is difficult to meet the effluent standard, and further treatment is required
The treatment of erythromycin membrane slurry using a single biochemical treatment cannot completely solve the problem, and necessary pretreatment must be carried out
The erythromycin membrane slurry pretreatment process consumes a lot of manpower and material resources due to the heavy load, long treatment cycle and high cost. Problems such as deodorization, antibiotic degradation and emission standards still need to be solved urgently

Abstract

The invention provides a method for processing erythrocin film slurry by virtue of hydrothermal carbonization reaction. The method specifically comprises the steps of firstly carrying out solid-liquidseparation on the erythrocin film slurry through coagulation and flocculation so as to obtain filter residues, adding a certain amount of catalyst into the filter residues, adding two suspension solutions into a reaction kettle, carrying out hydrothermal carbonization reaction, and after the hydrothermal carbonization reaction is finished, filtering, so as to obtain filter residues and filtrate,wherein the filter residues can be used as a fuel or can be used for preparing activated carbon through modification, and the filtrate is continuously applied to a water treatment procedure. Accordingto the method provided by the invention, the processing period of the erythrocin film slurry is greatly shortened, the cost is saved, and the resource reutilization is realized; and the hydrothermalcarbonization reaction is simple, the foul smell of the erythrocin film slurry can be removed through the hydrothermal carbonization reaction, and antibiotics in the erythrocin film slurry can be degraded, so that the method is economic and practical and has wide market prospects.

Description

technical field [0001] The invention relates to the fields of pharmaceutical wastewater treatment and solid waste treatment, in particular to a method for treating erythromycin film slurry by hydrothermal carbonization reaction. Background technique [0002] Pharmaceutical wastewater mainly includes four categories: antibiotic production wastewater, synthetic drug production wastewater, Chinese patent medicine production wastewater, and washing water and flushing wastewater in the production process of various preparations. The wastewater is characterized by complex components, high organic content, high toxicity, deep color and high salt content, especially poor biochemical properties, and intermittent discharge, which is difficult to treat industrial wastewater. With the development of my country's pharmaceutical industry, pharmaceutical wastewater has gradually become one of the important sources of pollution. How to deal with this type of wastewater is a difficult proble...
