A kind of solar push-flow circulation and reoxygenation device and method for eutrophic water body

Abstract

The invention discloses a solar plug flow circulation and reoxygenation device and method for a eutrophic water body, belonging to the fields of ecological management and water treatment. The solar plug flow circulation and reoxygenation device comprises a floating body playing a supporting role, a solar power supply device and a storage battery, wherein the floating body comprises three parallel floating plates, i.e., a first floating plate, a second floating plate and a third floating plate, two ends of two parallel rotating shafts are respectively arranged on the first floating plate and the third floating plate, the second floating plate is vertically arranged in the middle of the two parallel rotating shafts, one end of the second floating plate is provided with a DO (Dissolved Oxygen) device, and the solar power supply device and the storage battery are arranged in the middle of the second floating plate. The solar plug flow circulation and reoxygenation device also comprises a solar tracking device, a horizontal plug flow mixing platform, a horizontal plug flow mixing device, a vertical aeration transmission device and a vertical aeration circulating device. According to the invention, horizontal plug flow mixing circulation and vertical aeration circulation are combined, so that the two functions including reoxygenation and plug flow of the water body are unified.

Description

technical field [0001] The invention belongs to the field of ecological management and water treatment, and more specifically relates to a device and method for three-dimensional circulation and reoxygenation treatment of eutrophication, low dissolved oxygen, water stagnation, unconnected rivers, and lake water bodies. technical background [0002] Ecological restoration of polluted rivers and lakes is a new technology that has developed rapidly at home and abroad in recent years, and has broad application prospects. The pollution of rivers in my country is becoming more and more serious, especially small and medium rivers, because most of them surround residential areas, farmland, close to poultry farms, and are affected by fish ponds, small and medium-sized industries, etc., their water quality is seriously polluted. With the continuous acceleration of urbanization and industrialization, the functions and functions of water bodies are constantly weakened. Especially for u...

Problems solved by technology

[0015] Aiming at the problems existing in the prior art in the ecological restoration of eutrophic water bodies of rivers or lakes, the function of the aeration device is single and the water quality is poorly adaptable. The device and its method combine the horizontal push-flow mixing cycle and the vertical aeration cycle to realize the unification of the two functions of water body re-oxygenation and push-flow
