Description
Technical field
The present invention relates to that the water treatment combined system belongs to sewage treatment area in a kind of A/O biological reaction tank (Anoxybiotic-aerobic biologic reaction tank)-artificial swamp.
Background technology
China is a country that drought and water shortage is serious.The Freshwater resources total amount is 28000 billion cubic meters, account for 6% of water globe resource, be only second to Brazil, Russia and Canadian, occupy the 4th in the world, but have only 2300 cubic metres per capita, only be world average level 1/4, the U.S. 1/5, rank 121 in the world, be one of 13 countries that water resources is the poorest per capita in the whole world, and water resources is inhomogeneous at regional distributed pole, the water imbalance between supply and demand is very outstanding.Middle water reuse is one of main path of sewage recycling of water resource utilization.The water reuse is at the early-stage in China at present, and treatment technology is backward relatively, and running cost is bigger.
Summary of the invention
The object of the present invention is to provide water treatment device in a kind of artificial swamp, handle with centering water.
For achieving the above object, water treatment device mainly includes in worker's wetland provided by the invention:
Filtering grid connects aerated grit chamber;
This aerated grit chamber connects the bio-contact oxidation pretreatment pool;
The bio-contact oxidation pretreatment pool connects the A/O biological reaction tank
The A/O biological reaction tank connects distributing well
Distributing well connects second pond
Second pond connects artificial swamp;
It is 0.9 meter that packed height in the artificial swamp is not less than.
In the water treatment device, filtering grid comprises coarse rack and fine fack in the artificial swamp of the present invention, is connected by water pump between coarse rack and the fine fack, and fine fack connects aerated grit chamber.
Water treatment device wherein is connected with the bio-contact oxidation pretreatment pool between this aerated grit chamber and the A/O bio-contact oxidation pretreatment pool in the artificial swamp of the present invention.
In the water treatment device, between A/O biological reaction tank and the secondary sedimentation basins distributing well is installed in the artificial swamp of the present invention.
In the water treatment device, the filler in the artificial swamp is a pebbles in the artificial swamp of the present invention.
In the water treatment device, the filler in the artificial swamp is 8-15mm for the pebbles particle diameter in the artificial swamp of the present invention.
The present invention is with biology and the organic combination of the ecosystem, and the pre-treatment ability is strong, and the wetland floor space is little, has that to handle the water yield big, and water outlet is effective, and working cost is low, need not sterilization equipment, the characteristics of ecological safety and stable water outlet.
Description of drawings
Fig. 1 is a water treatment combined system combination synoptic diagram in A/O biological reaction tank-artificial swamp of the present invention.
Main label declaration in the accompanying drawing:
Coarse rack and water inlet pump house integral pool 1; Fine fack and sediment by aeration integral pool 2; Bio-contact oxidation pretreatment pool 3; A/O biological reaction tank 4; Distributing well 5; Second pond 6; Artificial swamp 7.
Embodiment
The technical problem to be solved in the present invention provides a kind of combined system of middle water reuse.The water treatment combined system comprises coarse rack and intake pump house integral pool 1, fine fack and sediment by aeration integral pool 2, bio-contact oxidation pre-treatment 3, A/O biological reaction tank 4, distributing well 5, second pond 6, artificial swamp 7 in the AO-artificial swamp.
Coarse rack and water inlet pump house integral pool draw water by water pump and are promoted to fine fack and aerated grit chamber, gravity flow then enters the catalytic oxidation pretreatment pool, organism and ammonia nitrogen are after this tentatively removes, gravity flow enters distributing well, after in distributing well, passing through water pump lifting, enter horizontal sedimentation tank, particulate matter flows into artificial swamp at this post precipitation and carries out advanced treatment.
In other words, the residence time of coarse rack and intake pump premises body integral pool 1 is 2h, is mainly used in the oarse-grained slag body of removing sanitary sewage, and fine fack and 2 desilting times of sediment by aeration integral pool are 4h, mainly precipitation and degradation particles organic matter.3 residence time of bio-contact oxidation pretreatment pool are 8h, are mainly used in the conversion of organic degraded and ammonia nitrogen.A/O biological reaction tank 4 is mainly used in dissolved organic matter and single removal.Distributing well 5 is mainly used in regulating pondage.Second pond 6 is mainly used in the mud that precipitate A/O biological reaction tank 4 runs off.The packing area filler of artificial swamp 7 is the pebbles filler, and the degree of depth that is mainly used in nitrogen is removed.The packed height of the packing area of artificial swamp 7 is not less than 0.9 meter, guarantees the anaerobic state of wetland bottom.Wetland is planted the power flower for preceding 1/3 section again, plants the mullet grass for back 2/3 kind.Artificial swamp is good to the intestinal bacteria removal effect, the processing efficiency height, so integrated artistic does not need sterilization.
Below in conjunction with invention, Fig. 1 is further described.Particulate matter in the sewage removes by filter more short grained impurity through fine fack earlier again after coarse rack removes by filter the impurity of larger particles, a water pump is installed between coarse rack and fine fack, makes the sewage of coarse rack can enter fine fack swimmingly.Flow into aerated grit chamber through the fine fack filtered sewage, the sedimentation of in aerated grit chamber, degrading of organic particulate matter in the sewage, then flow into the bio-contact oxidation pretreatment pool, organism and ammonia nitrogen carry out Degradation and Transformation in bio-contact oxidation pretreatment pool 3 after, dissolved organic matter is further degraded in A/O biological reaction tank 4, flow into distributing well 5 subsequently and carry out water distribution, second pond 6 further precipitates, the loss of the mud of precipitate A/O, flow into artificial swamp 7 and carry out advanced treatment, qualified discharge.
