Abstract
The invention discloses a combined controllable type efficient purification constructed wetland system. The system comprises a water distribution well, a first water pump, a second water pump, an aeration device, and a first-stage horizontal subsurface flow wetland unit, a second-stage vertical subsurface flow wetland unit and a third-stage horizontal subsurface flow wetland unit which are connected in series through pipelines, wherein the water distribution well is communicated with a water inlet of the first-stage horizontal subsurface flow wetland unit through a water inlet pipe; the first water pump is used for lifting effluent of the first-stage horizontal subsurface flow wetland unit to the second-stage vertical subsurface flow wetland unit, and the aeration device is used for carrying out aeration treatment on inflow water of the second-stage vertical subsurface flow wetland unit; and the second water pump is used for lifting effluent of the second-stage vertical subsurface flow wetland unit to the third-stage horizontal subsurface flow wetland unit. The operation mode is controllable, operation is easy and convenient, main factors influencing the wetland can be effectively controlled, implementation is effective, application is wide, and secondary pollution cannot be caused.
Description
technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a combined controllable and high-efficiency purification artificial wetland system. Background technique [0002] With the acceleration of my country's urbanization process and rapid economic development, the quality of life of residents has improved significantly, while the problem of water pollution has become increasingly prominent. Constructed wetland sewage treatment technology has been widely promoted and applied in the field of sewage treatment technology due to its advantages of small investment, simple operation, low operating cost, and good denitrification effect. It is commonly used in domestic sewage, sewage plant tail water and surface water treatment projects. [0003] Constructed wetlands are artificially constructed for sewage treatment facilities by simulating the structure and function of natural wetlands. Artificially build a pool or trench, lay an a...
