Problems solved by technology

[0007] The present invention aims to solve the problem that the existing artificial wetlands in small towns in cold regions cannot operate all year round, and the low-temperature strengthening measures not only increase the operating cost, but also complicate the operation management. During the low-temperature operation of the existing artificial wetlands, due to the decrease of dissolved oxygen in water, To deal with the technical problems with unsatisfactory effects, so as to provide a solar submerged intermittent aeration artificial wetland system applied to small towns in cold regions

specific Embodiment approach 1

[0019] Specific implementation mode one: combined with figure 1 and 2 The solar submerged layer intermittent aeration artificial wetland system applied to small towns in cold regions in this embodiment consists of a rectangular tank body (16), water inlet pipe (1), water outlet pipe (2), upper perforated water distribution pipe (3), The lower perforated water distribution pipe (4), the upper perforated water collection pipe (5), the lower perforated water collection pipe (6), multiple sets of perforated aeration pipes (7), the upper water distribution valve (8), the lower water distribution valve (9), Emergent plants (10), upper substrate (11), lower substrate (12), air pump (13), solar panel power supply device (14) and water retaining plate (15);

[0020] The outer layer of the solar latent layer intermittent aeration artificial wetland system applied to small towns in cold regions of the present embodiment is a rectangular tank body (16), and the water retaining plate (15)...

specific Embodiment approach 2

[0028] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the upper layer of the rectangular tank body (16) is filled with a porosity of the upper matrix (11) of 59.97%. Others are the same as the first embodiment.

specific Embodiment approach 3

[0029] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that: the lower layer of the rectangular tank (16) is filled with a porosity of the lower matrix (12) of 65.67%. Others are the same as those in the first or second embodiment.

Abstract

The invention discloses a solar subsurface intermittent-aeration constructed wetland system applied to small towns in a cold region and relates to a wetland system applied to the small towns in a cold region. The solar subsurface intermittent-aeration constructed wetland system is mainly used for solving the technical problems that an existing constructed wetland system for the small towns in the cold region cannot be operated throughout the year, is high in operation cost, complex in management, low in dissolved oxygen in water and not good in treatment effect. The solar subsurface intermittent-aeration constructed wetland system consists of a slot body, a water inlet tube, a water outlet tube, a water distributing tube, a water collecting tube, an aeration tube, a solar panel power supply device and a water baffle, wherein the water baffle is arranged below a frost line and used for dividing the slot body into upper and lower layers; the perforated aeration tube is arranged on the bottom of the lower layer of the slot body; the perforated aeration tube is communicated with an air outlet of the air pump; and a power supply input end of the air pump is connected with the solar panel power supply device. The solar subsurface intermittent-aeration constructed wetland system can be operated in cold small towns throughout the year, is low in operation cost and simple to operate, and the water quality of operating effluent in a freeze-up period meets the national sewage emission standards. The solar subsurface intermittent-aeration constructed wetland system disclosed by the invention is applied to the sewage treatment field.

Description

technical field [0001] The invention relates to a wetland system applied to small towns in cold regions. Background technique [0002] At present, many small towns in my country lack the necessary sewage treatment system. Due to the relatively backward infrastructure in small towns and rural areas, drainage pipelines are not fully built in many places, and the sewage formed by livestock, aquaculture and pesticides is directly discharged into rivers and lakes. has become an important source of pollution. On the one hand, small town sewage has the characteristics of large fluctuations in water quality and quantity, and low pollutant concentration; on the other hand, it requires low investment and operation costs for the treatment system, and simple operation control. Stability, high investment and operation costs, complex control) cannot solve the problem of sewage treatment in small towns. The sewage treatment system of small towns in cold regions is also required to operate...
