Description
Technical Field
The invention relates to the technical field of public health and water environment pollution prevention and control, in particular to an ecological wetland and a water purification method based on transverse hydraulic disturbance.
Background
The ecological wetland is a comprehensive ecological system, and the ecological wetland applies the principles of species symbiosis and material cycle regeneration in the ecological system and the principle of structure and function coordination, fully exerts the production potential of resources on the premise of promoting the virtuous cycle of pollutants in wastewater, prevents the re-pollution of the environment and obtains the best benefits of sewage treatment and resource utilization. The plants of the ecological wetland can also convey oxygen for the water body, so that the activity of the water body is increased. The wetland plants also play an important role in controlling water quality pollution and degrading harmful substances.
The microorganisms in the ecological wetland are the main force for degrading pollutants in the water body. Aerobic microorganisms decompose most organic matters in the wastewater into carbon dioxide and water through respiration, anaerobic bacteria decompose organic matters into carbon dioxide and methane, nitrifying bacteria nitrify ammonium salts, and denitrifying bacteria reduce nitrate nitrogen into nitrogen and the like. Through the series of actions, main organic pollutants in the sewage can be degraded and assimilated to become a part of microbial cells, and the rest of inorganic substances which are harmless to the environment return to the nature.
The ecological wetland also has the advantages that some protozoa and metazoan, even some wetland insects and birds can participate in swallowing organic particles deposited in a wetland system, and then the organic particles are absorbed as nutrient substances through assimilation, so that the particles in the sewage are removed to some extent.
Thorough mixing is the first and crucial concern for biochemical reactions. In this process, the hydrolysis products should diffuse rapidly into every detail of the water, so that all colloidal particles destabilize and agglomerate at almost the same moment, and a good reaction result is obtained. This process can be referred to as a primary coagulation process because colloidal particle destabilization and agglomeration occur simultaneously during the mixing process. The main role of this process is mixing and is therefore generally referred to as the mixing process. The simultaneous destabilization and coagulation of colloidal particles in water is a prerequisite condition for obtaining good flocculation effect, but the further improvement of coagulation effect is also hindered because people have unclear understanding on the effects of sub-micro mass transfer and turbulent microstructure in multiphase system reaction when the colloidal particles are initially coagulated.
Therefore, the ecological wetland and the water purification method based on the transverse hydraulic disturbance are provided.

The main role of this process is mixing and is therefore generally referred to as the mixing process. The simultaneous destabilization and coagulation of colloidal particles in water is a prerequisite condition for obtaining good flocculation effect, but the further improvement of coagulation effect is also hindered because people have unclear understanding on the effects of sub-micro mass transfer and turbulent microstructure in multiphase system reaction when the colloidal particles are initially coagulated.
