Sewage discharge point, remaining sediment deposition enters the heavy mud groove 33 of bottom of pond in water body in cistern 3, and the rainwater in cistern 3 is promoted
The start by set date under automaton effect of pump 32, extracts the water in cistern 3, and pass through water inlet manifold 7 and each water distributor
To 4 water distribution of composite medium artificial wet land, after water distribution stops, rainwater elevator pump 32 is closed by automaton, is started empty
Air pump, and pass through the tube wall pore of gas distribution pipeline 41 to purification sublayer middle layer supplemental oxygen, at the same can loose hole, prevent from blocking up
Plug；
When the water in cistern 3 is not enough at once, the river water in moisturizing pump sump 8 being extracted, and pass through by small pump 81
Water inlet manifold 7 and each water distributor are by the river water injected media composite type artificial wetland 4 of extraction, to ensure reuse water；
Flow into the micro-ecological environment that the water of composite medium artificial wet land 4 is built jointly in wetland plant 81 and purification sublayer
Under processing, the Conventional pollution in water body obtains fully degraded purification, and purified water body is collected by collector pipe and water header
Afterwards, control well 5 is flowed into through control pipe, passes through the highly controllable composite medium artificial wet land 4 processed of the control terminal nozzle of control pipe
Water level, to control the ratio of aerobic treatment in composite medium artificial wet land；
The water in well 5 is controlled to flow into clear water reserviors 6 by the water outlet of its underpart, in clear water reserviors 6 water body when being needed with water,
It can be exported by clear water elevator pump 63 to outside water spot such as greening irrigation, fire demand water etc., beyond 6 receiving capacity of clear water reserviors
Water body then flows into cistern 3 by clean water overflow mouth 62.
Obviously, above-described embodiment of the utility model is merely to illustrate that the utility model example, and is not
Restriction to the embodiment of the utility model.For those of ordinary skill in the art, on the basis of above description
On can also make other various forms of variations or variation.There is no need and unable to give poor example to all embodiments.
And these connotation changes and variations that derived from for belonging to the utility model still fall within the utility model
Protection domain.
