Technical field
This utility model is related to wastewater treatment equipment, and in particular to a kind of auto-flushing defecator.
Background technology
Filtration refers to that in the presence of extraneous motive force the fluid in the raw water of filter side passes through porous media
Passage flow to the other side of filter, the particulate matter in raw water is trapped, so as to realize fluid and particulate matter point
From.The filtrate used by defecator is generally quartz sand, and in water treatment procedure, the particulate matter in raw water is retained by filter material layer
Absorption is simultaneously constantly accumulated in filter material layer, and the space of filter material layer is gradually blocked by particulate matter, and is formed on the surface of filter material layer
Filter cake so that the strainability of defecator is reduced, at this time, it may be necessary to carry out backwash to defecator so as to recover to filter work(
Energy.
The backwash process of defecator needs to arrange single-minded backwashing pump and corresponding air compressing mechanism, by inciting somebody to action
Air is compressed in filter material layer, and with flowing of the air in filter material layer, the greasy dirt and particulate matter in filter material layer is removed,
During backwash can Jing often there is air and be filled with uneven situation, where in filter material layer, air charge is few, filter
Greasy dirt and particulate matter in material effectively can not be removed, when next filter cycle is put into, filter material layer local filtration load
Increase, particulate matter sink to inside from filtrate layer surface, and particulate matter pelletizing gradually increases, and while the extension to the inside of filter material layer, makes
Whole defecator failure.
