Problems solved by technology

However, the artificial wetland with free falling water can only increase the dissolved oxygen in the water body, but cannot increase the oxygen content in the matrix; the tidal wetland can only increase the oxygen content in the matrix, but cannot increase the dissolved oxygen in the water body
Although the two kinds of wetlands have partially solved the problem of insufficient oxygen content in traditional constructed wetlands, the oxygen content of constructed wetlands still needs to be further improved in order to further improve the sewage treatment effect of constructed wetlands

Abstract

The invention provides a multi-stage free drop wetland unit with tidal properties and a sewage treatment system. The multi-stage free drop wetland unit comprises multiple stages of free drop wetlands; every two adjacent free drop wetlands have different free drop heights; each free drop wetland is provided with an overflow port and a drain hole; the drain holes of the free drop wetlands are positioned below the overflow ports; when the water storage of the upper stage of free drop wetland is higher than the overflow port, water flows from the overflow port and the drain hole to the lower stage of free drop wetland; when the water storage of the upper stage free drop wetland is lower than the overflow port, water flows from the drain hole to the lower stage free drop wetland. The sewage treatment system comprises a flow dividing control device and more than two multi-stage free drop wetland units, wherein the flow dividing control device controls the multi-stage free drop wetland units to supply sewage intermittently. The multi-stage free drop wetland unit with tidal properties and the sewage treatment system have two functions of drop water oxygenation and tidal wetland substrate oxygenation, are high in sewage treatment efficiency and are economical and environment-friendly.

Description

technical field [0001] The invention relates to an artificial wetland and a sewage treatment system, in particular to a multi-stage free-falling wetland unit with tidal characteristics and a sewage treatment system. Background technique [0002] Constructed wetlands have developed rapidly at home and abroad in recent years because of their advantages such as low investment, low operating costs, good treatment effects, and simple processes. Traditional constructed wetlands mainly include: surface flow constructed wetlands, subsurface flow constructed wetlands and vertical flow constructed wetlands. However, because the plant root zone and microorganisms need to consume a large amount of dissolved oxygen in the process of absorbing and degrading pollutants, and these wetlands adopt a planar structure, the water flow is gentle, and the plant roots and substrates are soaked in water for a long time, resulting in the level of dissolved oxygen in the wetlands. Insufficient, sever...
