Ecological dam for aeration and slag blocking

Abstract

The invention discloses an ecological dam for aeration and slag blocking. The ecological dam comprises a rubber dam bottom, an on-dam frame, an upstream slag blocking plate, a downstream guard plate, a crossing floating bridge, floating bed bodies, a plastic film, wheat straw roller shutters, a scum tank, an aeration system and a photovoltaic wind energy generating system; the rubber dam bottom is of a bag type structure, high-strength synthetic fabric is adopted as a stressed framework of the rubber dam bottom, rubber is applied to the inner side and the outer side of the rubber dam bottom as protective layers, the two ends of the rubber dam bottom are fixed to a river bank, and the rubber dam bottom is expanded by filling water or inflating gas; the on-dam frame is arranged on the rubber dam bottom and is made of wood or welded through stainless steel materials, the lower half portion of the on-dam frame is made to be of a cuboid structure, and the upper half portion of the on-dam frame is made to be of an arc structure; the upstream slag blocking plate is arranged at one side of the upstream of a river, the downstream guard plate is arranged at one side of the downstream of the river, and the floating bed bodies are distributed on the water surface defined by the upstream slag blocking plate and the downstream guard plate; the floating bed bodies are made of wood, bamboo poles, nylon ropes, steel wires and filler blocks, and the aeration system comprises an aeration pump, a gas inlet pipe, a gas distribution pipe and aeration heads.

Description

technical field [0001] The invention relates to a watershed of river pollution control technology, in particular to an aeration slag-retaining ecological dam. Background technique [0002] Due to the accumulation of pollutants in rivers and other water bodies due to aquaculture, rainwater runoff, farmland receding water and other sewage discharges, the pollution of rivers and other water bodies has continued to increase, and the water environment has deteriorated day by day. In recent years, people's awareness of the ecological environment has become increasingly With deepening, the regulation of rivers and lakes has attracted more and more attention. People began to respect and protect the natural features and ecological functions of rivers, lakes and other water bodies. The harmonious development of man and nature. [0003] Ecological dams are one of the in-situ restoration technologies for rivers and lakes. Aquatic plants are planted on ecological dams to allow aquatic p...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is: in order to overcome and solve the problems of low temperature in winter, the failure of plants and aquatic organisms to grow normally, and the problem of salvaging floating objects in rivers, the present invention provides an aeration system with simple structure and convenient operation and management. The slag-retaining ecological dam can intercept and salvage floating objects in the river, purify the river water, beautify the environment, and at the same time perform biochemical treatment on the river, prolong the growth cycle of plants, improve purification efficiency, and achieve higher economic and ecological benefits
