Description
Technical field
The invention belongs to technical field of sewage more particularly to a kind of sewage disposal systems with water inlet sterilizing function
And its control method.
Background technique
In general, the bulk properties of hospital sewage are similar to general sanitary sewage, but than chemistry contained by sanitary sewage
Ingredient is increasingly complex, and more outstanding is in hospital sewage containing a large amount of bacterium and pathogen, due to hospital's displacement per capita
Greater than city domestic sewage displacement, so the organic indicator in hospital sewage is generally lower than city domestic sewage.
Medical sewage disposal device in the prior art generallys use Liquid level when sterilizing, be equipped with three in waste water treatment box
The different control valve of a height is from top to bottom respectively as follows: lower limit control valve, disinfection control valve and draining control valve.It is low in liquid level
When sterilizing control valve, water inlet is also without disinfection in waste water treatment box.When liquid level is located at disinfection control valve and draining control valve
Between when, continuous sterilization processing is carried out in waste water treatment box.It, may be for a long time when the mode liquid level is in disinfection control valve or less
It does not sterilize, pollutes.It when liquid level is located between disinfection control valve and draining control valve, may sterilize for a long time, have and disappear
The disadvantage of toxic effect fruit difference.
Summary of the invention
For disadvantages described above, first technical problem to be solved by this invention is to provide a kind of with water inlet sterilizing function
