Description

technical field

[0001] The invention relates to water body purification equipment for subsurface flow wetlands, in particular to a disturbance type artificial subsurface flow wetland water body purification treatment equipment and a purification method. Background technique

[0002] Since the 1970s, water treatment technology of constructed wetlands has attracted people's attention. It has the advantages of low investment and low energy consumption, and has become a research hotspot in water environment technology. Subsurface flow wetland is a new technology of artificial wetland sewage treatment, which is an artificially constructed, controllable and engineered wetland system.

[0003] Currently, existing subsurface wetlands include three key components: plants, microorganisms, and substrates. Fillers with different particle sizes are artificially constructed to form a bed for the matrix. Water-resistant plants with high decontamination efficiency are planted on the surfac...
