Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] Such as figure 1 As shown, the present invention provides a two-stage enhanced denitrification intelligent constructed wetland system, which includes an oxygen-enriched water collection tank 1, an enhanced nitrification section 2, a closed monitoring well 3 in the middle section, and an enhanced denitrification section 4 arranged in sequence according to the direction of water flow. With the terminal monitoring well 5, each building is connected sequentially through pipelines. Among them, the oxygen-enriched water collection tank 1 is used to increase the oxygen content of DO in the influent water and provide aerobic nitrification conditions for nitrogen pollutants; the enhanced nitrification section 2 mainly performs nitrification and partial denitrification; the closed monitoring well 3 in the middle section mainly uses To monitor water qual...

Abstract

The invention relates to a two-stage enhanced denitrification intelligent constructed wetland system. The system comprises an oxygen-rich water pool, an enhanced nitrification section, a middle section closed monitoring well, an enhanced denitrification section and an end monitoring well which are sequentially arranged in a water flowing direction, and all above structures are serially connected by a pipeline; the enhanced nitrification section and the enhanced denitrification section are used to remove pollutants in water in stages; the middle section closed monitoring well monitors the quality of water discharged from the enhanced nitrification section in real time; the end monitoring well monitors the quality of water discharged from the enhanced denitrification section in real time; and the middle section closed monitoring well is cooperated according to the monitoring data of the middle section closed monitoring well and the end monitoring well in order to determine the carbon source of the wetland system, accurately add a carbon source and build a wetland running database according to the monitoring data. The system has the advantages of high efficiency in removing pollutants, especially TN, intelligent control, realization of modular combination of wetlands, and suitableness for purifying water with different scales.

Description

technical field [0001] The invention relates to a two-stage enhanced denitrification intelligent artificial wetland system, which is applicable to the fields of river course management, rural domestic sewage decentralized treatment, rural non-point source pollution control, water source protection and the like. Background technique [0002] Compared with traditional water treatment technologies, constructed wetlands have the characteristics of less investment, low operating costs, stable treatment effects, and strong impact resistance. This technology uses the synergistic purification effect of substrate, plants and microorganisms to remove pollutants in water. Constructed wetland technology was originally used as a means of secondary treatment of domestic sewage. With the development of market demand, constructed wetlands have gradually become a means of advanced treatment in various sewage treatment plants. In recent years, constructed wetlands have become an ecological T...
