Background

The artificial wetland sewage treatment system has the advantages of low construction and operation cost, simple and convenient management and better effluent quality. The artificial wetland not only can reduce pollutant discharge and realize sewage reuse, but also has landscape function and obvious social and environmental benefits. The artificial wetland can be divided into surface flow, horizontal subsurface flow, vertical subsurface flow and the like, wherein the vertical subsurface flow artificial wetland is concerned by the advantages of strong oxygen delivery capacity, good hydraulic load, low environmental dependence of pollutant removal effect and the like.

The hydraulic retention time of the artificial wetland is longer, the artificial wetland generally belongs to large-scale environmental engineering projects, the occupied area is large, the capital construction period is long, the investment amount is high, and certain limitation is brought to the application and popularization of the artificial wetland.

(2) The function is single. At present, most artificial wetlands excessively strengthen the water quality purification function, and have low attention on additional functions such as landscape aesthetics, rest, science popularization education and the like. Nowadays, ecological civilization construction is vigorously advocated in China, so that the creation of the ornamental experience type artificial wetland is more favorable for exerting the ecological environment function and landscape benefit of the artificial wetland, realizing the sustainable utilization of the artificial wetland and meeting the higher requirements of urban residents on the living environment.

(3) The construction, operation and maintenance difficulty of the water transmission and distribution system is high. The traditional artificial wetland is often arranged in an area with less human smoke and larger free land area due to larger occupied area and is far away from a domestic sewage discharge source, so a complex and huge sewage collecting, conveying and distributing system is required to be matched; if the treated effluent reaches the standard and tries to be recycled, the treated effluent needs to be conveyed through a long-distance pressure pipeline, so that the matching construction cost and the operation and maintenance cost of the traditional artificial wetland are higher.

(4) The total amount of plant organisms is less. The plants of the traditional artificial wetland are horizontally arranged in a single layer, the biomass amplification means is usually improved through plant varieties and planting density, the means is limited, the biomass increment is not obvious, the plant biomass is positively correlated with the sewage treatment efficiency, and the sewage treatment efficiency is low.
