Characteristics of hospital sewage treatment:

Hospital sewage contains some special pollutants, such as drugs, disinfectants, diagnostic agents, detergents, and a large number of pathogenic microorganisms, parasite eggs and various viruses. In addition, the sewage from hospitals with isotope clinics also contains radioactive substances such as radium 226, phosphorus, gold 198, and iodine 131. Compared with industrial wastewater and domestic sewage, it has the characteristics of small water volume and strong pollution ability. If it is allowed to discharge, it will inevitably pollute the water source and spread diseases. Therefore, hospital sewage treatment is required.

1. Calcium hypochlorite disinfectant:

It is an inorganic compound. It is a white granular solid with a chlorine odor. The sewage treatment chemicals are highly soluble in water and can be formulated into various concentrations. The resulting sodium hypochlorite solution is a transparent, green to yellow liquid. With strong disinfection ability and low price, it is widely used in many fields such as industrial wastewater treatment, medicine, fine chemicals, sanitation and disinfection.

2. TCCA disinfectant:

Trichloroisocyanuric acid is a kind of chloroisocyanuric acid compounds, and it is an important bleach, chlorinator and disinfectant. The effective chlorine content of TCCA is 90%, which can effectively kill intestinal pathogenic bacteria, pyogenic coccus, pathogenic yeast and other pathogenic bacteria, and effectively improve the sewage water quality of hospital.
