Abstract
The utility model discloses a vertical current constructed wetland structure, which is characterized in that a water distributing pipe (1) and a water collecting pipe (2) are respectively located at the upper half parts of a downstream tank (3) and an upstream tank (4); the downstream tank (3) and the upstream tank (4) are adjacent and are communicated at the bottoms; gravel layers, coarse sand layers and fine sand layers are added in sequence. The constructed wetland is used for various sewage processing, has the characteristics that the efficiency is high, the energy consumption is low, the investment is low, the running management level requirement is not high and the like, and is a more economical and reasonable engineering technology for town sewage processing. The constructed wetland system adopts all-day automatic intermittent water injection, and the scale of processing sewage by the system is about 2000m<3>/d under the normal running condition.
Description
Technical field
The utility model relates to a kind of structure of vertical current constructed wetland.
Background technology
Artificial swamp is for various sewage disposals, and the advantage such as have that efficiency is high, energy consumption is low, it is low to invest and operation and management level is less demanding is that town sewage is processed the rational engineering of less expensive.Meanwhile, because phosphorus is important factor and even the limiting factor of various body eutrophications, so sewage dephosphorization has great importance for controlling body eutrophication.Thereby the treatment effect of sewage phosphorus has important theoretical using value in research artificial wet land system.
Summary of the invention
The technical problems to be solved in the utility model is: provide that a kind of efficiency is high, energy consumption is low, it is low to invest and the waste disposal plant of the advantage such as operation and management level is less demanding.
The technical solution of the utility model is: a kind of structure of vertical current constructed wetland, water distributor and header lay respectively at the first half in downstream tank and up pond, downstream tank and bottom adjacent with up pond communicates, and add gravel bed successively, coarse sands layer and fine sand layer.
Fine sand particle diameter is 0.2-0.4cm, and coarse sand particle diameter is 1-2cm, and grain size of gravel is 3-5cm.
The height of header is lower than water distributor.
The beneficial effects of the utility model: artificial swamp is for various sewage disposals, the advantage such as have that efficiency is high, energy consumption is low, it is low to invest and operation and management level is less demanding, is that town sewage is processed the rational engineering of less expensive.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of structure of vertical current constructed wetland, water distributor 1 and header 2 lay respectively at the first half in downstream tank 3 and up pond 4, downstream tank 3 and bottom adjacent with up pond 4 communicates, and add gravel bed successively, coarse sands layer and fine sand layer.Fine sand particle diameter is 0.2-0.4cm, and coarse sand particle diameter is 1-2cm, and grain size of gravel is 3-5cm; The height of header 2 is lower than water distributor 1.
Sanitary sewage evenly flows into downstream tank by water distributor 1, and infiltration, flows into 4 bottoms, up pond through downstream tank 3 bottom selfs downwards, and make progress through the sand bed in up pond 4, by header 2, collect subsequently, then flow into water collecting basin by rising pipe, finally by water pump, extract and be discharged in water outlet storage pool.Thereby in fact the sewage that flows into artificial swamp passed through the processing in 2 times (downstream tank and up ponds).In addition, this artificial wet land system adopts the water filling of whole day automatic batch-type, and under normal running (operation) conditions, the scale that this system is disposed of sewage is about 2000 m
3/ d.
Vertical current constructed wetland is positioned at the Zhu Jiajian town, Zhoushan, Zhejiang Province (29 53 N, 122 23 E) of southeast China, mainly for the treatment of the sanitary sewages such as hotel, restaurant and local resident of landscaped area, Zhu family point Nansha, artificial swamp area approximately 3000 m
2(vertical stratification of artificial swamp is shown in Fig. 1).Sanitary sewage evenly flows into downstream tank by water distributor, and infiltration downwards flows into bottom, up pond through downstream tank bottom self, and make progress through the sand bed in up pond, by header, collect subsequently, then flow into water collecting basin by rising pipe, finally by water pump, extract and be discharged in water outlet storage pool.Thereby in fact the sewage that flows into artificial swamp passed through the processing in 2 times (downstream tank and up ponds).In addition, this artificial wet land system adopts the water filling of whole day automatic batch-type, and under normal running (operation) conditions, the scale that this system is disposed of sewage is about 2000 m
3/ d.
Claims (3)
1. the structure of a vertical current constructed wetland, it is characterized in that: water distributor (1) and header (2) lay respectively at the first half of downstream tank (3) and up pond (4), downstream tank (3) and bottom adjacent with up pond (4) communicates, and add gravel bed successively, coarse sands layer and fine sand layer.
2. the structure of a kind of vertical current constructed wetland according to claim 1, is characterized in that: fine sand particle diameter is 0.2-0.4cm, and coarse sand particle diameter is 1-2cm, and grain size of gravel is 3-5cm.
