At the beginning of the emergence of modern ophthalmology in my country, it often existed in the name of “prevention of blindness”. But at present, the scope of ophthalmic medical services in my country has undergone tremendous changes. But with the increase in the amount of sewage, how to deal with the sewage of the ophthalmology hospital?
With the liberalization of the government’s policy to encourage private medical institutions, private capital that attaches great importance to investment benefits has begun to invest heavily in the medical field, injecting new vitality into the medical market, and more private capital will be injected into specialized medical care. Take cataracts and glaucoma as two common eye diseases. At least hundreds of millions of people worldwide suffer from these two diseases. Therefore, in the future, the ophthalmology medical market has a bright future, and the market size of China’s ophthalmological medical treatment will continue to rise steadily.
The birth of private capital has led to the rapid rise of ophthalmology chain medical care, sharing the pressure of national medical and health work, providing superior medical conditions for the public, and benefiting the society. At the same time, the environmental protection issues of medical units are also of particular concern.
1. Water quality characteristics and standard limits of ophthalmic medical wastewater: The main pollutants contained in medical wastewater are: parasite eggs, organic matter, floating and suspended matter, etc. The total amount of bacteria in the untreated raw sewage reaches 10^8 Pieces/mL or more. The total number of bacteria in most of the medical wastewater in my country reaches several million to tens of millions per milliliter, of which the number of coliforms per milliliter of sewage is mostly more than 200,000, and the detection rate of intestinal pathogens is 30%-99.99%.
2. Mainstream treatment process: From the perspective of sewage treatment, it can be divided into physical and chemical treatment and biochemical treatment.
Uses biological contact oxidation + precipitation + disinfection process, that is, A/O process treatment. The function of the A/O process is nitrification and denitrification. The key point of the design is to focus on the sterilization and disinfection methods of sewage and sludge, mainly sterilization and disinfection.
