Intelligent control system for horizontal flow constructed wetland

Abstract

The invention relates to an intelligent control system for a horizontal flow constructed wetland. The intelligent control system comprises a water inlet area, a filtering area, a water outlet area, awater quality monitoring unit and an aeration unit, wherein the water inlet area, the filtering area and the water outlet area are sequentially communicated in the horizontal direction; the water quality monitoring unit is used for monitoring the water quality of the water inlet area and the water outlet area, and the aeration unit is arranged in the water inlet area and is connected with the water quality monitoring unit; the water inlet area is communicated with the constructed wetland and is used for storing discharged water of the constructed wetland; the filtering area can filter water flowing into the water inlet area and discharge the water into the water outlet area; the water quality monitoring unit can start the aeration unit to aerate the water inlet area when monitoring that the water quality parameters of the water inlet area and the water outlet area are not within a preset range. The water quality of the water inlet area and the water outlet area is monitored in real time through the water quality monitoring unit, when the water quality is poor, the aeration unit is started to increase the oxygen content in the water inlet area, the purpose of oxygenation of the constructed wetland system is achieved, the degradation capacity of microorganisms in the constructed wetland system to pollutants in water is improved, and the treatment effect of the constructed wetlandis guaranteed.

Description

technical field [0001] The invention belongs to the technical field of water environment treatment, and in particular relates to an intelligent control system for a horizontal flow artificial wetland. Background technique [0002] Constructed wetland technology is an engineering application technology that simulates the natural wetland system to treat river sewage. Under a specific water environment, it can purify and treat upstream river sewage through the synergy of physics, chemistry and biology. It has the advantages of short cycle, low operating cost, good sewage treatment effect, and can beautify the landscape environment. It is applied in the technical fields of black and odorous river treatment and water environment ecological restoration. [0003] According to the direction of water flow in constructed wetlands, constructed wetlands are divided into horizontal flow constructed wetlands and vertical flow constructed wetlands. The horizontal flow constructed wetland ...
