Sewage treatment device for hospitals

Abstract

The invention discloses a sewage treatment device for hospitals. A water feeding pipe is connected with a regulating box; an active carbon filter is arranged on the water feeding pipe; the water feeding pipe is connected with a setting tank through a first water pump; the setting tank is connected with a disinfecting box through a connecting hole; the disinfecting box is connected with an ozone feeding pipe; the water feeding pipe is connected with an aeration biological filtering box through the first water pump; a supporting layer is arranged in the aeration biological filtering box; a filtering layer is arranged above the supporting layer; an aeration pipe is arranged between the supporting layer and the filtering layer; a backwash water feeding pipe and a backwash air feeding pipe arearranged under the supporting layer; the aeration biological filtering box is connected with a purified water tank through the connecting hole; the purified water tank is connected with a water draining pipe; a second water pump is arranged on the water draining pipe. The sewage treatment device adopts aeration biological filtration, is capable of effectively solving the purifying problem of hospital sewage and achieving high effluent quality, is simple and stable to run and is worthy of popularization.

Description

technical field [0001] The invention belongs to the technical field of medical sewage treatment, and in particular relates to a hospital sewage treatment equipment. Background technique [0002] Medical sewage is mainly the sewage discharged from the hospital's consulting room, laboratory, ward, laundry room, X-ray room and operating room, etc. The source and composition of the sewage are very complicated. Hospital sewage contains a large number of pathogenic bacteria, viruses and chemical agents, and has the characteristics of space pollution, acute infection and latent infection. [0003] Biological aerated filter is a new sewage treatment process developed on the basis of ordinary biological filter in the late 1980s and early 1990s. It can remove SS, COD, BOD, nitrification, denitrification, phosphorus removal, AOX and other toxic substances. Due to the complex sources and components of medical sewage, the water quality is poor in uniformity and contains a large number ...

AI Technical Summary

Problems solved by technology

Because the sources and components of medical sewage are very complex, the water quality is poor in uniformity, and contains a large number of viruses and bacteria

At present, the existing medical wastewater treatment equipment has a simple structure and a single treatment method. Most of them only perform simple disinfection and discharge, which has great potential safety hazards and pollutes the environment.
