AI Technical Summary

Problems solved by technology

[0002] Drugs are necessary to protect the health of human beings, animals and plants, and the waste water produced by them has a high COD concentration, complex components, and difficult treatment.
If the wastewater is not treated and discharged directly into the environment, it will cause serious pollution to the environment.
At present, the treatment methods of organic wastewater from synthetic pharmaceuticals mainly include physical and chemical methods, chemical methods, and biochemical methods. These methods are either high in treatment costs, or difficult to discharge in a stable manner.

Abstract

The invention introduces a treatment method of organic wastewater of synthetic pharmacy. The treatment method comprises the processes of reduction of CO2 pressurized manganese-aluminum-zinc composite powder, anaerobic treatment, aerobic treatment, biological filtration tower treatment and the like. The treated wastewater can be stably discharged up to a standard.

Description

technical field [0001] The invention relates to a treatment method for synthetic pharmaceutical organic wastewater. Background technique [0002] Drugs are necessary to protect the health of human beings, animals and plants, and the waste water produced by them has a high COD concentration, complex components, and difficult treatment. If the wastewater is not treated and directly discharged into the environment, it will cause serious pollution to the environment. At present, the treatment methods of synthetic pharmaceutical organic wastewater mainly include physical and chemical methods, chemical methods, and biochemical methods. These methods are either high in treatment costs or difficult to meet the discharge standards stably. It is of great practical value to develop a treatment method for synthetic pharmaceutical organic wastewater that is low in cost and can be discharged stably. Contents of the invention [0003] Aiming at the problems of the current synthetic pha...
