Problems solved by technology

The combination of wetlands only considers hydraulic factors and the function of removing all pollutants, but fails to consider practical functions. Different regions target different pollutant factors (BOD 5 , ammonia nitrogen, total nitrogen, total phosphorus) functions are designed in a targeted manner; in addition, due to the linear relationship between the concentration of pollutants in the water and the direction of water flow, a large number of pollutants in the water remain in the front section of the wetland, resulting in an increased decomposition burden for plants , while the concentration of pollutants in the latter stage is relatively low, and the efficiency of plants to decompose pollutants is reduced

Embodiment Construction

[0033] Attached below Figure 1~2 The present invention will be further described in detail with reference to specific embodiments. However, it should not be understood that the scope of the above subject matter of the present invention is limited to the following embodiments, and all technologies realized based on the content of the present invention belong to the scope of the present invention.

[0034] The purpose of this system is to combine different types of wetlands in a targeted manner, solve the targeted removal effect of constructed wetlands on water pollutant factors (ammonia, nitrogen, phosphorus), and maximize the functions of different types of wetlands. And by adjusting the direction of water flow and hydraulic conditions (, adjust the function and function of the constructed wetland, increase the pollutant degradation load of each treatment unit, restore the treatment efficiency of different sections of the constructed wetland, and avoid the difference and oper...

Abstract

The invention provides a composite reciprocating constructed wetland water purification system and a water purification method. The system comprises a first functional unit and a second functional unit located below the first functional unit. And the second functional unit is arranged below the subsurface flow constructed wetland. Through the design of the advection, subsurface flow and vertical flow composite constructed wetland, the functions of the constructed wetland are further improved according to the characteristics of a micro-polluted water body, the load efficiency of each unit is improved, and the comprehensive problems of single form, single function and single effect are solved.

Description

technical field [0001] The invention relates to the technical field of purification of polluted water, in particular to a composite reciprocating artificial wetland water purification system and a water purification method. Background technique [0002] Constructed wetlands mainly remove water pollutants through physical interception, chemical reaction, and biodegradation to achieve the purpose of purifying water quality. The pollutants in the water body are the nutrients needed for plant growth. The forms of constructed wetlands are mainly divided into surface flow type, subsurface flow type and vertical flow type according to the different ways of water flow. In the surface-flow constructed wetland, water flows through the surface of the wetland to form a layer of shallow water with uniform depth; the main function is to deposit particulate pollutants on the surface of the soil carrier of the wetland, and to degrade beneficial substances in the water through plants, so as...
