Aerobiont membrane wastewater treatment device

Abstract

The invention relates to an aerobiont membrane wastewater treatment device which comprises an upper part arranged on a water surface, a lower part arranged under the water surface, and an air pipe 5 connecting the upper part on the water surface and the lower part under the water surface, wherein the upper part on the water surface comprises a solar cell 1, an air pump 2 and a water floating platform 3; the lower part under the water surface comprises an air / water current lifting pipe 4, a biomembrane moving-burden bed reactor 6 and a guide plate 11; and one end of the air pipe 5 is connectedwith an air conveying port of the air pump 2 of the upper part on the water surface and the other end of the air pipe 5 is connected with the bottom of the air / water current lifting pipe 4 of the lower part under the water surface, which is close to the position of the guide plate 11, so that the upper part on the water surface is connected with the lower part under the water surface. The aerobiont membrane wastewater treatment device has a biodegradation function, and has the function of ensuring that an oxygen-rich water body on the surface of a water body and an oxygen-poor water body at the bottom of the water body are exchanged, so that oxygen content in water is increased, activity of aerobiont is enhanced, and finally targets of degrading organic matters, nitrogen and phosphorus in the water body and controlling the advantages of growth of bluegreen algae are achieved.

Description

technical field [0001] The invention relates to an aerobic biofilm treatment device, which belongs to the technical field of environmental engineering. It specifically relates to a waste water aerobic biofilm waste water treatment device driven by solar energy for the treatment and purification of surface water bodies (such as lakes, rivers, reservoirs and ponds) and other non-point source pollution. The device has the functions of increasing dissolved oxygen in water bodies and degrading organic pollution in water substances and remove ammonia nitrogen, and promote the mixing of water flow. The device can also be used for the enhancement of wastewater biological treatment oxidation ponds and artificial wetlands to enhance the removal effect of pollutants. Background technique [0002] At present, the technology applied to the pollution of surface water bodies such as lakes, rivers and reservoirs mainly uses the physical action of water circulation to achieve the mixing o...

Problems solved by technology

[0003] In order to overcome the defects that the existing SolarBee solar energy-driven long-distance circulation technology cannot oxygenate water and remove organic matter and ammonia nitrogen, the technical purpose of the present invention is to provide a new type of solar energy-driven, used for surface water surface source pollution treatment. Air oxygenation improves the aerobic biofilm wastewater treatment device, so that the equipment not only has the function of circulating surface water with the solar-driven long-distance circulation technology of the prior art, but also has the function of using solar energy to oxygenate the surface water, thereby removing organic matter and ammonia nitrogen. effect
