Problems solved by technology

[0002] The pharmaceutical industry is a traditional pillar industry in my country. With the development of the pharmaceutical processing industry, the amount of industrial wastewater and waste gas is increasing. The sewage generated and discharged is also one of the sources of industrial sewage. Pharmaceutical sewage mainly includes four types, animal Serum pharmaceutical sewage is a kind of bioengineering pharmaceutical sewage. It contains various complex pollutants such as high toxicity, ammonia nitrogen, and formaldehyde. It has complex components, deep color, and is difficult to degrade. Most manufacturers directly discharge it without treatment. It has caused great pollution to the environment, and there are even reports that some sewage plants use sprinklers to discharge sewage into the sewer in points, which is extremely harmful, and now the country has put forward new requirements for environmental protection, which has caused people to pay more attention to environmental protection

Embodiment 1

[0025] A pharmaceutical wastewater treatment process includes the following steps:

[0026] A. First, pass the sewage through the grid pool to remove the floating objects in the sewage;

[0027] B. Send the above-mentioned treated sewage into the adjustment tank, adjust the water quality, degrade a part of CODcr and chromaticity, and enter the iron-carbon micro electrolytic cell through the lower filter layer of the adjustment tank, and then send the above-mentioned treated sewage into the catalyst In the oxidation tank, the sewage generates strong oxidizing hydroxyl radicals through the oxidation-reduction reaction, which causes the ring-opening and chain-scission oxidation of organic pollutants;

[0028] C. Send the above-mentioned treated sewage into the pH adjustment tank, add quicklime to adjust the pH to 8-10, then pass it into the aeration adjustment tank, and send it to the biological oxidation tank through the aeration adjustment tank;

[0029] D. The above-mentioned sewage e...
