Integrated buoy type solar driven stream-making aerator and water body in-situ remediation method

Abstract

The invention relates to a eutrophic water source in-situ remediation device and method. The device is an integrated buoy type solar driven stream-making aerator. The aerator comprises a solar cell system, a suspended carrier, a guide cylinder, an aeration system and a positioning system, wherein the solar cell is pyramidal and on the upper part of the suspended carrier; the lower part of the suspended carrier is integrated with the guide cylinder to provide buoyancy for the device; the cavity of the carrier is provided with an air pump, the solar cell is on the upper surface of the carrier; an aeration disc is at the bottom of the inside of the guide cylinder and connected with the air pump through an air delivery pipe; and the guide cylinder is provided with a water inlet and a water outlet correspondingly. The aerator uses the solar cell for power supply, thus the efficient oxygenation of the stream-making aerator can be effectively realized without causing secondary pollution, the outbreak of algae in the polluted water body can be controlled, the decomposition of organic substances in a water body can be promoted, the water body can be remedied and a self-cleaning function can be realized. The integrated buoy type structure floating on the water surface does not occupy land, has a compact structure and a small volume and is easy to transport and install.

Description

technical field [0001] The invention belongs to the field of water treatment, and relates to an aeration device in the industry of repairing polluted water bodies and an in-situ repair method for nutrient-rich water bodies. Background technique [0002] In recent years, with the rapid development of my country's social economy, the discharge of water pollutants has increased year by year. Urban and rural drinking water sources are generally polluted to varying degrees, and the pollution is increasing, seriously threatening people's lives and health. Most small towns in my country use surface water such as small and medium-sized rivers, lakes and reservoirs as drinking water sources. Due to urban industrial wastewater, rural domestic sewage, domestic garbage, livestock and poultry breeding waste discharge, and non-point source pollution from pesticides and fertilizers, about 15,000 small towns have suffered serious water pollution, and more than 10,000 small towns are serious...

Problems solved by technology

At the same time, compared with the technical solution in the present invention, the solar panel of the buoy-type solar-driven aerator in Chinese patent 200910047293.8 is placed flat, which is not conducive to receiving sunlight, reduces the utilization rate of light energy, and also causes birds and waterfowl perched on it, and their feces will cover the solar panels, further hindering the use of light energy; on the other hand, the aeration method without time limit increases the energy demand, so that the solar panel area must be large enough to meet the power supply demand, and at the same time Its power supply system uses an inverter to convert direct current into alternating current for use by the air compressor. Its limited conversion efficiency further causes waste of energy, making the device bulky and inconvenient for transportation and application; while dissolved oxygen in nutrient-rich water during the day Sufficient, no need for artificial aeration, but will promote the growth of algae, can not better achieve the effect of improving water quality
