Abstract

The invention relates to an artificial wetland for processing a saliferous water body in northwest district. The artificial wetland is formed by a settling pond, an overland flow pond, a hygrophyte pond and a hydrophyte pond which are sequentially connected through an overflow dam, wherein one end of the settling pond is provided with a controlled inflow port, and the other end of the settling pond is provided with an abyssal region; the overland flow pond comprises a plurality of ridges; a channel is formed between each two adjacent ridges; salt-resistive xerophytes are planted on the ridges; salt-resistive hygrophytes are planted in the hygrophyte pond; salt-resistive hydrophytes are planted in the hydrophyte pond; and the bottom parts of the settling pond, the overland flow pond, the hygrophyte pond and the hydrophyte pond are respectively provided with a steady gradient in downward trend from each inlet and each outlet. The invention also provides a method for processing the saliferous water body in the northwest district by utilizing the artificial wetland. The artificial wetland is suitable to be used in the northwest district in China and the problem that a large number of lake water bodies have serious salinization can be solved.

Description

technical field [0001] The invention belongs to the field of water treatment and relates to an artificial wetland for treating saline water in Northwest China. Background technique [0002] Constructed wetland is a unique "soil-plant-microbe" ecosystem constructed artificially, that is, it is composed of soil or sandstone matrix, aquatic plants, microorganisms and other inhabiting animals in the depression stratum that simulates the natural environment. Ecological environment, assimilation and dissimilation of pollution conversion, both physical mechanism (such as: precipitation, filtration and adsorption), chemical mechanism (such as: redox, adsorption, ion exchange and complexation reaction) and biological mechanism (such as: biological assimilation Absorption, mineralization and decomposition, assimilation and absorption of plants), has the advantages of no need for mechanical equipment and energy input, low technical level, low operation and maintenance requirements,...
