Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings.

[0013] Such as figure 1 As shown, a hospital sewage treatment system includes: a chemical reaction tank, a biological reaction tank, a filter tank and a disinfection tank connected in sequence, and is characterized in that: an ion exchange adsorption resin column and an ion exchange adsorption resin column are also arranged between the filter tank and the disinfection tank Neutralization pool.

[0014] The outlet end of the filter tank is connected to the inlet end of the ion exchange adsorption resin column, the outlet end of the ion exchange adsorption resin column is connected to the inlet end of the neutralization tank, and the outlet end of the neutralization tank is connected to the The inlet ends of the disinfection pools are connected.

[0015] The filler of the ion exchange adsorption resin column is a strongly acidic cation exchange resin used for adsorbing...

Abstract

The invention discloses a hospital sewage treatment system which comprises a chemical reaction pool, a biological reaction pool, a filtering pool and a disinfection pool, wherein the chemical reaction pool, the biological reaction pool, the filtering pool and the disinfection pool are sequentially connected. The system is characterized in that an ion-exchange adsorption resin column and a neutralization pool are arranged between the filtering pool and the disinfection pool. According to the hospital sewage treatment system, by means of the arrangement of the ion-exchange adsorption resin column, heavy metal in sewage can be effectively absorbed, water after being absorbed by the ion-exchange adsorption resin column is sour, and after being neutralized to be neutral in the neutralization pool and being disinfected in the disinfection pool, the water finally meets discharging standards.

Description

technical field [0001] The invention relates to a hospital sewage treatment system, in particular to a system specially for treating heavy metals in hospital sewage. Background technique [0002] Hospital sewage contains some special pollutants. At present, some existing hospital sewage treatment systems can treat drugs, disinfectants, diagnostic reagents, detergents and a large number of pathogenic microorganisms, parasites and viruses. However, Cannot effectively remove heavy metals from diagnostic reagents or other sources of contamination. Most heavy metals such as mercury, lead, cadmium, arsenic, etc. are not necessary for life activities, and heavy metals have a certain accumulation effect in the human body after ingestion, and when the concentration exceeds a certain level, they will be toxic to the human body. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a hospital sewage treatment system capable of r...
