Since the 21st century, the pharmaceutical industry has been developing rapidly. Its industry scale ranks at the middle level of 26 industries. China has a population of about 1.4 billion. There is a great demand for disease treatment and rehabilitation. Especially in recent years, with the increasing aging of China's population and the increasing number of new people, the development of China's pharmaceutical industry has been greatly accelerated. At the same time, pharmaceutical wastewater from the pharmaceutical process has become one of the important pollution sources that affect people's living environment. How to effectively treat pharmaceutical wastewater and how to adopt effective treatment technology have become important issues in the development of pharmaceutical enterprises.

China's pharmaceutical industry can be divided into traditional Chinese medicine production and western medicine production according to the components of drugs produced. Therefore, wastewater from the pharmaceutical industry can also be divided into wastewater from traditional Chinese medicine production and wastewater from western medicine production. The product forms of traditional Chinese medicine include pills, tablets, capsules, oral liquid, etc. According to the production link of wastewater, it can be divided into cleaning water, cooking water, cleaning water, and domestic sewage, among which the amount of wastewater discharged in the cooking link is the largest and the degree of environmental pollution is the highest. According to the product category and technological process, the wastewater from western medicine production includes antibiotic production wastewater, synthetic drug production wastewater, cleaning wastewater, and flushing wastewater produced by various technological processes, etc.

Pharmaceutical wastewater has complex components, high organic matter content, high toxicity, deep color, high salt content, poor biochemistry, and intermittent discharge, which is a kind of industrial wastewater that is difficult to treat. Pharmaceutical wastewater effluent treatment technology includes physical treatment, chemical treatment, and biological treatment. The physical and chemical treatment methods can be used as pretreatment means to improve the biodegradability of wastewater, and can also be used as advanced treatment methods to discharge effluent up to standard. The main physical and chemical treatment methods are coagulation, adsorption, air flotation, ion exchange, and membrane separation.

The chemical method is a traditional method for wastewater treatment. Oxidation, electrolysis, and advanced oxidation are common. Biological methods include aerobic treatment and anaerobic treatment such as activated sludge and biofilter. At present, biological treatment is the preferred treatment technology at home and abroad. The activated sludge process is the most classic and low-cost treatment measure.

Membrane bioreactor technology is a new wastewater treatment technology that combines membrane separation technology with biotechnology. It uses a membrane separation module to intercept activated sludge and macromolecular organic matter in a biochemical reaction tank instead of the secondary sedimentation tank, which improves the concentration of activated sludge and ensures the effluent quality, thus greatly enhancing the function of the bioreactor. The membrane bioreactor consists of the bioreactor, membrane module, and pump. According to the setting position and pressurization mode of the bioreactor and membrane module, it can be divided into the external type and submerged type. Membrane generally can be divided into microfiltration membrane, ultrafiltration membrane, nanofiltration, and reverse osmosis membrane according to the size of the surface aperture. Microfiltration membrane and ultrafiltration membrane are commonly used in the membrane bioreactor reaction treatment process.
