Description

Technical Field

[0001] The invention relates to the technical field of biomedicine treatment, in particular to a wastewater treatment agent for biomedicine production. Background Art

[0002] The pharmaceutical industry and the biomedical engineering industry are the two pillars of the modern pharmaceutical industry. The biomedical industry is composed of the biotechnology industry and the pharmaceutical industry. The definition and scope of the biotechnology industry are not uniform among countries and organizations, and even the views of different people are often very different. Biomedical engineering is a general term for the comprehensive application of the principles and methods of life sciences and engineering sciences, and the understanding of the structure, function and other life phenomena of the human body at multiple levels of molecules, cells, tissues, organs and even the entire human body system from an engineering perspective, and the research of artificial materials, products, devices and system technologies used for disease prevention, disease treatment, human function assistance and health care.

[0003] Most of the existing wastewater treatment agents use raw materials including polyaluminium chloride and waste acid. Although polyaluminium chloride can purify water, it may cause secondary pollution to the water source. The treated wastewater may contain polyaluminium chloride residues and pollutants such as organic matter. If not properly disposed of, it will cause serious secondary pollution to the environment. At the same time, waste acid is a hazardous waste, which has the risk of transfer and use. In addition, waste acid contains a variety of harmful substances. Long-term use will cause poisoning to microorganisms and affect the sewage treatment effect. In addition, some wastewater treatment agents are corrosive to equipment, which will corrode the treatment equipment or pipelines, increasing the maintenance cost and replacement frequency of the equipment.

The present invention achieves the same effect of waste acid through environmentally friendly acid while reducing the harm and preventing the problem of re-pollution.

[0023] 3. The present invention is provided with polyferric sulfate. Although traditional polyaluminium chloride can purify water quality, it may cause secondary pollution to the water source; the treated wastewater may contain polyaluminium chloride residues and pollutants such as organic matter, which will cause serious secondary pollution to the environment if not properly disposed of. The present invention can be used as a substitute for polyaluminium chloride by providing polyferric sulfate, especially when phosphorus removal is required, and its phosphorus removal effect is more significant and the cost is lower. In addition, polyferric sulfate can also be used for deep COD removal, removal of suspended matter and colloidal substances. In most coagulation treatments, polyferric sulfate can basically replace polyaluminium chloride, and is suitable for urban sewage, food processing industry, papermaking, chemical industry, food, etc., and has environmental protection effects.
