Aeration oxygenation system for accelerating purifying of water body of constructed wetland

Abstract

The invention provides an aeration oxygenation system for accelerating purifying of a water body of a constructed wetland. The aeration oxygenation system can be suitable for the constructed wetland and can increase the content of oxygen in the water body. The aeration oxygenation system comprises a riverbed (1) and a dam (2). A trapezoidal intercepting dam (3) used for intercepting the riverbed (1) is arranged on the riverbed (1). An aeration machine room (4) is arranged on the dam (2) and internally provided with an aeration machine (5) and a controller (6). A header pipe (7) is connected to the aeration machine (5) and provided with a plurality of water pipe connectors (8). Aeration branch pipes (9) are connected to the water pipe connectors (8). The other ends of the aeration branch pipes (9) are sealed. Aeration fine pipes (10) are arranged on the aeration branch pipes (9). An aeration main valve (11) is arranged on the aeration header pipe (7). Aeration branch valves (12) are arranged on the aeration branch pipes (9). Check valves (13) are arranged in the aeration thin pipes (10).

Description

technical field [0001] The invention relates to the technical field of aeration and oxygenation structures, in particular to an aeration and oxygenation system for accelerating the purification of artificial wetland water bodies. Background technique [0002] Constructed wetland is a new type of sewage treatment process developed in the 1970s. At present, constructed wetland has been gradually applied to the advanced treatment of domestic sewage and industrial wastewater. The physical, chemical and biological triple synergy in the system realizes the purification of sewage. [0003] In the activated sludge method of sewage, the dissolved oxygen of the mixed liquid must be replenished by aeration method. The traditional oxygenation method includes the cyanobacteria agent method and the impeller rotating agitation method.

Problems solved by technology

[0003] In the activated sludge method of sewage, the dissolved oxygen of the mixed liquid must be replenished by aeration method. The traditional oxygenation method includes the cyanobacteria agent method and the impeller rotating agitation method. The former uses the cyanobacteria agent to quickly dissolve the original polluted water body and deodorize it. , combined with a variety of restoration technologies to achieve the purpose of purifying the river water body and optimizing the aquatic ecosystem. The disadvantage is that this technology cannot be directly applied to the constructed wetland system, and the scope of application is small; the latter stirs the water surface through the impeller rotary brush, making Activated sludge maintains a suspended state and continuously contacts the atmosphere with new interfaces to increase the oxygen content in the water body. The disadvantage is that the aeration range is small and the aeration effect is not good, which causes the defect that the oxygen content in the water body cannot be effectively increased. Therefore, Designing an aeration and oxygenation system that can be applied to constructed wetlands and increase the oxygen content in water to accelerate water purification in constructed wetlands is of great significance for improving the purification efficiency of constructed wetlands
