The Ecological Environment Present Situation Assessment And Wetland Ecosystem Construction In Lake Wabu

Wabu lake is the largest lake in the huaihe river basin in anhui, as well as the surrounding residents of drinking water, and chaohu constitutes the proposed "lead Jiang Jihuai" two important water bodies of water mains. The main content of this paper include wabu lake basin water pollution research and evaluation, wabu lake benthic animal community structure characteristics, the steep rivers and building of the ecological wetland treatment system design, the construction of the ecological wetland east fei rivers. Thesis mainly includes the following sections:(1) to understand the status quo of wabu lake water quality and its main pollutants, according to the August 2011-December 2014 monitoring data of wabu lake lake water body, in November 2011 and August 2011-wabu lake main monitoring data in and out of the lake river and the reference of related literature data processing and evaluation method, the water quality status of wabu lake basin analysis, evaluation, provide the basis for river basin water pollution prevention and control.(2) study the basic indicators and zoobenthos wabu lake basin in 2012 spring, summer, autumn, winter four times the number of species, density index such as dynamics, discusses the benthic animal community structure features and its relationship with the water environment, biodiversity protection and evaluation for wabu lake flow guide Jiang Jihuai project’s influence on the water ecology provides scientific basis and support.(3) build a steep ravine river ecological wetland:the wide scope of application of the vertical flow constructed wetland+surface flow constructed wetland "the combination of technology, in addition, combined with stabilization pond in front of the process; Steel slag, activated carbon adsorption as a filler, such as sand and gravel packing as matrix; To choose wetland plants are:reed, Mosaic rushes, willow, cattail, flowers, canna and windmill grass again. The setting up of water inlet total brake, the stabilization pond is decorated in the fishpond, outlet arrangement in pond area downstream the narrowest place, and will be part of overflow dam, dam built another Duan Jiancheng above the surface of the river.(4) using the east fei rivers of low-lying land, the construction of artificial wetland treatment system, the upstream water purification. Upstream river water through the sluice will import the wetland treatment system, and then the future water into grit chamber, stabilization pond, ecological gravel bed and table flow wetland system, through a series of physical and biological treatment, and finally to intake.
