Problems solved by technology

[0003] Existing pharmaceutical wastewater is generally treated by biochemical degradation methods. However, pharmaceutical wastewater containing organic toxins such as antibiotics has a disinfecting effect on biological bacteria, which inhibits the growth of biological bacteria, resulting in wastewater containing antibiotics. It is difficult to degrade by conventional biological methods, how to deal with this kind of wastewater has become a difficult problem in environmental protection today

Embodiment 1

[0029] refer to figure 1 , a treatment method for pharmaceutical waste water of the present invention comprises the following treatment steps:

[0030] Step 1) Primary ozone oxidation process: pharmaceutical wastewater is oxidized by ozone to treat toxins such as antibiotics;

[0031] Step 2) Biodegradation process: Biodegradation of pharmaceutical wastewater that has treated toxins such as antibiotics;

[0032] Step 3) Secondary oxidation process: the pharmaceutical wastewater degraded by biological bacteria is subjected to secondary oxidation to disinfect biological bacteria and other toxic and harmful bacteria;

[0033] Step 4) Precipitation process: the pharmaceutical wastewater after the sterilization of biological bacteria is subjected to sedimentation treatment;

[0034] Step 5) Discharge or reuse: The pharmaceutical wastewater after the above treatment is tested for water quality, and after reaching the standard, it is directly discharged or reused in the production ...

Embodiment 2

[0041] see further figure 2 , the present invention also discloses another treatment method for pharmaceutical wastewater, comprising the following treatment steps:

[0042] Step 1) Primary ozone oxidation process: pharmaceutical wastewater is introduced into the reactor, ozone is oxidized, and toxins such as antibiotics are treated;

[0043] Step 2) Biodegradation process: Biodegradation of pharmaceutical wastewater that has treated toxins such as antibiotics;

[0044] Step 3) Precipitation process: the pharmaceutical wastewater degraded by biological bacteria is subjected to sedimentation treatment;

[0045] Step 4) Secondary oxidation process: the precipitated pharmaceutical wastewater is subjected to secondary oxidation to disinfect biological bacteria and other toxic and harmful bacteria;

[0046] Step 5) Discharge or reuse: The pharmaceutical wastewater after the above treatment is tested for water quality, and after reaching the standard, it is directly discharged or...

Abstract

The invention discloses a pharmaceutical wastewater treatment method. The pharmaceutical wastewater treatment method comprises the following steps: firstly carrying out primary ozonation on pharmaceutical wastewater, treating toxins like antibiotics, then carrying out biochemical degradation by virtue of biological bacteria, then carrying out secondary oxidation on the biochemically degraded wastewater, killing biological bacteria and other toxic and harmful bacteria, finally carrying out sedimentation treatment, and directly discharging the pharmaceutical wastewater up to the standard or recycling the pharmaceutical wastewater into a production process by virtue of recycling equipment. The pharmaceutical wastewater treatment method has the advantages that ozone is adopted as an oxidizing agent and is discharged out in a gas form after oxidation is completed, no residue or pollution is produced, and no adverse impact is produced to follow-up treatment. meanwhile, a design working procedure is simple, flow operation is easy, and the treated wastewater can meet the standard emission requirement, so that the pharmaceutical wastewater treatment method is good and is a development direction of the pharmaceutical wastewater treatment in future.

Description

technical field [0001] The invention relates to the technical field of industrial wastewater treatment methods, in particular to a treatment method for pharmaceutical wastewater. 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. [0003] Existing pharmaceutical wastewater is generally treated by biochemical degradation methods. However, p...
