Medical waste water, including coagulation device, pre-conditioning unit, two stage treatment device and tertiary treatment device
Coagulation device is connected to the row of medical waste water mouthful, for the solids in removal medical waste water.At this
In embodiment, coagulation device includes grid, and grid removes solids in a manner of intercepting.Specifically, grid installation medical treatment
At the discharge outlet of waste water, using artificial grid, grid gap 10mm, main function is floating material in waste water, paper scrap, fiber, larger
Particle and suspended matter carry out intercept process, to mitigate the processing load of follow-up water treatment technology, and play protection water pump, pipeline,
The effects that instrument.
Pre-conditioning unit is connected to coagulation device, for receiving the medical waste water being discharged through coagulation device, and
Buffer the flow and flow rate of medical waste water.In the present embodiment, pre-conditioning unit includes having the regulating reservoir of preset volume (preferably
Ground is pre- gas explosion regulating reservoir) and wind turbine, regulating reservoir is for buffering the flow and flow rate into medical waste water therein so that medical treatment
Waste water is discharged with constant flow and flow rate, and wind turbine is used for the waste water in stirring and adjusting pond to prevent the suspended matter in medical waste water
Precipitation.In the present embodiment, regulating reservoir can eliminate peak load with regulating pondage, it is ensured that water outlet is uniform below；Simultaneously in pond
Wind turbine aeration agitation regulating water quality is arranged, prevents suspended particulate from precipitating, by macromolecular substances and indissoluble substance decomposition at being easy to
Biodegradable substance makes its treatment effect not to be interfered because of change of water quality.
Two stage treatment device is connected to pre-conditioning unit, for receiving the medical waste water being discharged from pre-conditioning unit, and is made
