Hospital wastewater treatment and recycling equipment with efficient sterilization and disinfection functions

Abstract

The invention provides hospital wastewater treatment and recycling equipment with efficient sterilization and disinfection functions. The hospital wastewater treatment and recycling equipment with theefficient sterilization and disinfection functions comprises a treatment pond body; a water inlet ditch is formed in one end of the treatment pond body; one end of the water inlet ditch extends intothe treatment pond body and is communicated with an adjusting pond; a grille trash blocking device is welded in a cavity of the water inlet ditch; an aeration pipe network is fixedly connected to thebottom of a cavity of the adjusting pond through a steel hoop; one end of the aeration pipe network extends out of the adjusting pond and is connected with an air pump through threads; a submersible sewage pump is fixedly connected to the side wall of the adjusting pond; and a first blow-off pipe is connected to an outlet of the submersible sewage pump through threads. The hospital wastewater treatment and recycling equipment with the efficient sterilization and disinfection functions, provided by the invention, has the advantages that the water quality and pH value of sewage are adjusted by using the adjusting pond because the adjusting, the grille trash blocking device, an oxidation pond, a sedimentation tank, a sludge pond, a sterilization tank and a sludge drying device are arranged, and a problem that the sewage treatment effect is poor due to unstable pH value is solved.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a hospital sewage treatment and recovery device with high-efficiency sterilization and disinfection functions. Background technique [0002] Hospital sewage refers to the sewage discharged from hospitals to the natural environment or urban pipelines. The water quality varies with the nature, scale and location of different hospitals. The amount of sewage discharged by each hospital bed is about 200-1000L per day. The main pollutants contained in hospital sewage are: pathogens (parasite eggs, pathogenic bacteria, viruses) etc.), organic matter, floating and suspended matter, radioactive pollutants, etc. If the sewage with pollution sources is not treated and purified, it will cause great harm to the environment and the human body. There are many ways to treat hospital sewage in the prior art , but the effect is not good, the technology is immature, and for la...
