Abstract

A velamen biology reaction treating equipment for hospital sewage belongs to device for sewage treatment; inside the bottom of dump tank is installed the aerator pipe with through hole, the outer side of which is connected with aerator. The framework is installed in the dump tank and sealed fulcrum bar is installed on the lower part of framework, the inside of which is velamen. The lower face of velamen contacts with sealed fulcrum bar and cooperates with each other in seal. Both ends of collector pipe links with upper face of velamen in seal and connects with collector tank, and the self-priming pump connects with collector tank. With a simple structure and low price, the device is of stable operation, long service life, no harmful gas generated in operation, good effect of sewage treatment, little output of sludge and favor for environmental protection.

Description

Membrane biological reaction formula Hospital Sewage Treatment device

Technical field

The utility model belongs to sewage disposal device, relates generally to a kind of diaphragm type Hospital Sewage Treatment device.

Background technology

Contain oxious components such as more solid residue, organic suspension thing, all kinds of pathogenic bacterium, virus, parasitic ovum in the hospital sewage, as not handling to it, not only can cause environmental pollution, even can cause that the breaking out with popular of communicable disease, serious harm human life and health.At present, physical processing apparatus can only be removed organic suspension thing and the solid residue in the hospital sewage, but can not sterilize; Organism in the existing biological treating equipment degradable sewage, but still retaining the suspended substance that carries bacteriophage in a large number in the draining after handling, make the operation of postorder disinfection become very difficult again, wastewater treatment efficiency is not good enough.In addition, existing biological treating equipment operational management is technical stronger, and managerial personnel's cultural quality and state of the art are had relatively high expectations.

Summary of the invention

The purpose of this utility model is exactly technical problem and the defective that exists at above-mentioned existing Hospital Sewage Treatment equipment, requirement in conjunction with the Hospital Sewage Treatment relative national standards, design provides a kind of novel membrane biological reaction formula Hospital Sewage Treatment device, reaches the purpose that increases substantially the Hospital Sewage Treatment quality, reduces the requirement of equipment operation level of management.

Basic design of the present utility model is, is provided with the aeration tube that has through hole is installed on the foul water tank inside bottom surface, and the aeration tube outer end is connected with aerator; Frame body is fitted in foul water tank inside, be positioned at the aeration tube top, sealing pole is installed on the frame body bottom, diaphragm is fitted in frame body inside, the diaphragm lower surface contacts cooperation with sealing pole, and sealing pole is closed the sealing of diaphragm lower surface, and header one end and diaphragm upper surface are tightly connected, the header the other end is connected on the header tank, and vacuum primingpump is communicated with header tank.

The utility model is simple in structure, and is cheap, respond well to Hospital Sewage Treatment, and water outlet can directly be discharged, and reaches regulated discharge standard; Sludge yield is little, and handles thoroughly; No obnoxious flavour produces, free from extraneous odour; Stable equipment operation, fault is few, generally utilization and operation about a year continuously; Floor space is little, only is the 1/3-1/5 area of conventional equipment.In addition, because pollutant load is few in the water outlet, virus and bacterium also greatly reduce, and make to disinfect to become easier and effective.

Embodiment

Below in conjunction with accompanying drawing the utility model optimum implementation is described in detail.Membrane biological reaction formula Hospital Sewage Treatment device comprises foul water tank 5, aerator 7, vacuum primingpump 3 and is arranged on sewage import 9 on the foul water tank 5, is provided with on foul water tank 5 inside bottom surface the aeration tube 6 that has through hole 8 is installed, and aeration tube 6 outer ends are connected with aerator 7; Frame body 4 is fitted in foul water tank 5 inside, be positioned at aeration tube 6 tops, sealing pole 10 is installed on frame body 4 bottoms, diaphragm 11 is fitted in frame body 4 inside, diaphragm 11 lower surfaces contact cooperation with sealing pole 10, and sealing pole 10 is closed the sealing of diaphragm 11 lower surfaces, and header 12 1 ends and diaphragm 11 upper surfaces are tightly connected, header 12 the other ends are connected on the header tank 2, and vacuum primingpump 3 is communicated with header tank 2.On header 12, install valve 1.

During operation, hospital sewage enters in the foul water tank 5 from sewage import 9, while inoculation of activated-sludge in sewage, and in the lump aeration tube 6, diaphragm 11 are flooded, aerator 7 enters air the sewage continuously from aeration tube 6 and through hole 8, and sewage permeates to inner centre hole through diaphragm 11 outsides, rejects organic pollutant in the sewage under diaphragm 11 effects, utilize organism and pathogenic bacteria in the active sludge decomposition sewage simultaneously, play and kill most bacterium and virus function; Open valve 1, under vacuum primingpump 3 suctions, the water outlet in the diaphragm 11 is sucked in the header tank 2 through header 12, or directly discharging, or carry out the postorder sterilization and disinfection and handle.

Claims
