One end of water water inlet pipe connects with water-locator, and the other end of former water water inlet pipe stretches out outside housing, and aerator is arranged
On water-locator and be socketed in and draw on sand passage, effluent weir is arranged on case top, effluent weir and enclosure interior
Connection.
Preferably, aerator farther includes first annular aeration head, the second annular aeration head, the first trachea
It is socketed in draws on sand passage with the second trachea, first annular aeration head and the second annular aeration head coaxial line, the
One trachea connects with first annular aeration head, and the second trachea and the second annular aeration head connection, so by air
Introduce in water-locator, improve rate of oxygen in water, make the ammonia nitrogen in water carry out nitration reaction, remove the ammonia in water
Nitrogen.
It is highly preferred that the diameter of first annular aeration head more than second annular aeration head diameter, such second
The annular more first annular aeration head of aeration head is near drawing sand passage.
It is highly preferred that one end of the first trachea connects with first annular aeration head, the other end of the first trachea sets
Put in case top and stretch out housing；One end of second trachea connects with the second annular aeration head, the second trachea
The other end be arranged on case top and stretch out housing.
It is highly preferred that the cross-sectional area of first annular aeration head and the second annular aeration head is reverse V-shaped, so
Prevent activity from considering sand plug plug.
Preferably, sand-washing device includes multiple curved tube, and curved tube is along the circumferential direction looped around and draws outside sand passage.
Compared with prior art, the beneficial effects of the utility model are: this utility model provides a kind of activity
Sand filter, this filter introduces air in water-locator, improves rate of oxygen in water, and oxygen utilization rate is high,
Save space, complete coagulation, filtration and nitrification at same filter, remove SS, phosphorus and ammonia in sewage simultaneously
Nitrogen.
Accompanying drawing explanation
The schematic diagram of a kind of active sand filter that Fig. 1 provides for this utility model.
Detailed description of the invention
The preferred implementation provided this utility model with reference to the accompanying drawings illustrates.
The preferred implementation of a kind of active sand filter that Fig. 1 provides for this utility model.As it is shown in figure 1,
This active sand filter, including housing 10, former water water inlet pipe 20, filter sand cleans device 30, air promotes dress
Pump 40, water-locator 50, aerator 60 and effluent weir 70, filter sand clean device 30 include drawing sand passage 31,
Sand-washing device 32, washed-out sand controlling organization 33 and rinse water outlet 34, draw sand passage 31 and be arranged on housing 10
Inside center, the bottom drawing sand passage 31 is connected with air lift 40, draws the top of sand passage 31 even
Logical sand-washing device 32 and rinse water outlet 34, washed-out sand controlling organization 33 is arranged on outside housing 10 and and sand-washing device
32 connect, in water-locator 50 is arranged on housing 10 and be socketed in and draw on sand passage 31, and former water water inlet pipe 20
One end connect with water-locator 50, the other end of former water water inlet pipe 20 stretches out outside housing 10, aerator 60
Being arranged on water-locator 50 and be socketed in and draw on sand passage 31, effluent weir 70 is arranged on housing 10 top,
Effluent weir 70 is internal with housing 10 to be connected, and the filtrate in housing 10 can be discharged housing 10 by effluent weir 70.
Sand-washing device 32 includes multiple curved tube, and curved tube is along the circumferential direction looped around and draws outside sand passage 31.
Aerator 60 farther includes first annular aeration head the 61, second annular aeration head the 62, first trachea
