Wherein, a pair of of branch pipe of triple valve 19 is connected to each other with the first water pipe 20 and the second water pipe 21 respectively；The supervisor of triple valve 19 with return
Flow tube 22 is connected to each other；First water pipe 20 is connected to each other with outdoor sewer；Return pipe 22 protrudes into clarifying chamber 10, and return pipe 22 goes out
The first ball-cock assembly 23 is equipped at the mouth of a river, the liquid level of clarifying chamber 10 of septic tank 3 or more is arranged in the first ball-cock assembly 23, floating for first
The liquid level high limit of a control reflux is arranged in ball valve 23, when the height that the liquid level of the clarifying chamber of septic tank 3 10 reaches setting is prescribed a time limit, the
The floating ball of one ball-cock assembly 23 floats, and stops reflux.Under normal conditions, the sewage of septic tank 3 can enter coarse filtration by clarifying chamber 10
Unit enters back into tower biological filter element, and the whole liquid level of septic tank 3 is caused to decline.When draining pump 418 starts, catchment
The clear water (draining at this time is the clear water after processing, has met discharge standard, has no longer been sewage) of case can first flowing back into
The clarifying chamber 10 of manure pit 3, when the height that the liquid level of clarifying chamber 10 is in the first ball-cock assembly 23 is prescribed a time limit, clear water stops reflux, remaining is clear
Water drains into outdoor sewer.
In the technical scheme, the second ball-cock assembly 46 in tower biological filter element 24 controls inflow, first by the
The setting of two ball-cock assemblys 46 is prescribed a time limit, the floating ball of the second ball-cock assembly 46 rises control in some high limit of intaking when liquid level reaches this height
It no longer intakes, when liquid level slightly declines, then the first aqueduct 410 for passing through the first water inlet 42 can be replenished in time into water.It will stream
The water outlet height of the Universal pipe 49 of amount control device is arranged near the high limit of the second ball-cock assembly 46, and the height of water outlet
Be it is arbitrarily adjustable, when water outlet height is prescribed a time limit lower than the floating ball height of the second ball-cock assembly 46, then water outlet can be constantly discharged, when
When water outlet is slowly turned up, the water flow of water outlet can be gradually decreased, until after water outlet is no longer below high limit, water outlet
It is turned up again, water outlet will not be all discharged.Therefore the difference in height limited according to the floating ball height for adjusting water outlet and the second ball-cock assembly 46,
The inflow of tower biological filter element required for can determining.
In the technical scheme, under the installation of tower biological filter element 24 is with earth's surface, the first water inlet 42, the are passed sequentially through
One aqueduct 410, the second water inlet 47 enter the first water tank 44 of the discharge of sewage control unit of the inside of filter tank shell 41
It is interior, since the second ball-cock assembly 46 in the first water tank 44 is connected with the first aqueduct 410, when the height of floating ball is not up to set
When definite value, the second ball-cock assembly 46 conducting, sewage enters the inside of the first water tank 44, and the floating ball of final second ball-cock assembly 46 is with dirt
The entry altitude of water rises, and after the height of the floating ball of the second ball-cock assembly 46 reaches setting value, the second ball-cock assembly 46 is closed, sewage
Shut off, sewage is during perfusion, when the height for the water outlet that the place height of sewage is slightly above Universal pipe 49, due to even
Logical device principle, sewage are exported from the Universal pipe 49 being connected to the lower surface of the first water tank 44, and due to gravity, sewage flows into second
In water tank 45, exports, flow on plate water distributor 411 using the second water outlet 48 of 45 lower surface of the second water tank, led to
It crosses plate water distributor 411 and uniformly flows into water distribution in sewage packed tower 412 afterwards, micro- life can be grown on sewage packed tower 412
Object forms microbial film, and microbial film absorbs the organic pollutant in sewage, and organic pollutant is decomposed and utilized,
Convenient for the growth of microbial film, sewage flows into following header tank 413 after sewage packed tower 412, then passes through draining pump
418 discharge the clear water in header tank 413.Sewage flows through the first water tank 44, the second water tank 45, plate in this process
Water distributor 411, sewage packed tower 412 and header tank 413 make the influence of country sewage time change be reduced to zero, and no matter moment is dirty
Water be it is how many, be all bound to enter according to the firm discharge of setting in filter tank shell 41, enhance filter tank to greatest extent
Impact resistance.This equipment does not have electrical equipment, is truly realized zero energy consumption.This equipment device category and quantity are few, substantially
There is no failure problems, securely and reliably.This equipment is not needed artificially to control, be truly realized unattended once installation.
In the technical scheme, change excrement unit, coarse filtration unit and tower biological filter element 24 both can be used as one it is whole
Body construction is mounted on same position, can also under the condition of insufficient space, dispersed placement.
In the technical scheme, tower biological filter element is aerated by the way of gravity-flow ventilation.Blast pipe
416 the shell 41 in filter tank interior side, extend downward into the high limit liquid level of header tank 413 or more, air-exhausting duct 415 is mounted on filter
The interior side of pond shell 41, the exhaust outlet of air-exhausting duct 415 stretch out the outside of filter tank shell 41 from the side surface of filter tank shell 41,
Enhance exhaust effect.
In the technical scheme, when draining pump 418 breaks down in order to prevent, Nobody Knows, so on draining pump 418
Provided with accident warning device.Warning device is water outlet one pressure warning unit of connection in draining pump 418, this device is steady
Fixed operation is limited to 5 years or more in year.When 413 liquid level of header tank of tower biological filter element reaches high limit, 413 liquidometer of header tank
43 when needing to start draining pump 418, and simultaneous pressure warning device starts to detect the pressure of the second aqueduct 417, if draining pump
418 to run well, then have hydraulic pressure in the second aqueduct 417, then pressure warning unit is not alarmed at this time, when 418 work of draining pump
Make exception, then no pressure in the second aqueduct 417, pressure warning unit opens alarm at this time.
It in the technical scheme, further include draining pump 418, which belongs to self priming pump, is mounted on discharge of sewage control
The top of the plate water distributor 411 of unit, the second aqueduct 417 and liquidometer 43 connecting with draining pump 418 are arranged at
In blast pipe 416,413 bottom of header tank is extended to.The start and stop of draining pump 418 are linked by the liquidometer 43 in header tank 413 to be controlled
System.The side for the second aqueduct 417 being connected with draining pump 418 is equipped with non-return valve, after preventing draining pump 418 from shutting down, with row
The clear water for the second aqueduct 417 that water pump 418 is connected flows back to the header tank 413 of bottom.If be connected with draining pump 418
The second aqueduct 417 in clear water flow back to the header tank 413 of bottom, starting draining needs first to draining pump 418 every time
Air discharge in second aqueduct 417, causes the drainage procedure time longer.
