Embodiment Construction

[0027] The present invention will be further explained below in conjunction with the drawings.

[0028] Such as figure 1 As shown, the treatment system for eutrophic wastewater includes a water absorption device, a magnetic flocculation device, a disk drive reoxygenation device, and a floating bed device. The water absorption device extracts sediments and interstitial water from the surface sediment of the eutrophic wastewater; The magnetic flocculation device is connected with the water absorption device to form the eutrophic waste water extracted by the water absorption device into magnetic flocs; one side of the reoxygenation device of the disk drive is connected with the magnetic flocculation device, and the other side is connected with the floating bed device. The reoxygenation device is composed of a magnetic disk mechanism, a magnetic seed recovery device and a nano-micro bubble generator. The magnetic disk mechanism magnetically separates the magnetic flocs to form magneti...

Abstract

The invention belongs to the field of sewage treatment, and particularly relates to a eutrophic wastewater treatment device and method. The eutrophic wastewater treatment system comprises a water absorption, a magnetic flocculation device, a disk drive reoxygenation device and a floating bed device, wherein the water absorption device is used for extracting deposits of surface layer sediment of eutrophic wastewater and interstitial water thereof; the magnetic flocculation device is connected with the water absorption device and used for forming the eutrophic wastewater extracted by the water absorption device into magnetic floccules; one side of the disk drive reoxygenation device is connected with the magnetic flocculation device, and the other side is connected with the floating bed device; the disk drive reoxygenation device is composed of a disk mechanism, a magnetic seed recovery device and a nano microbubble generator; the disk mechanism is used for carrying out magnetic separation on the magnetic floccules to form magnetic sludge; the magnetic seed recovery device is used for recovering magnetic seeds; the nano microbubble generator is used for fusing the purified eutrophic wastewater into a gas-liquid homogeneous stream; and the floating bed device is an aquatic plant ecological floating bed.

Description

technical field [0001] The invention belongs to the field of sewage treatment, in particular to a treatment device and method for eutrophic waste water. Background technique [0002] At present, eutrophication and the resulting algae blooms and the degradation of water ecosystems not only restrict the availability of river and lake resources, but also directly affect the healthy survival of human beings and the sustainable development of social economy. The restoration of degraded water ecosystems is also a major global problem. [0003] Eutrophication refers to the fact that under the influence of human activities, the water body receives excessive nutrients such as ammonia and phosphorus, which causes algae and other zooplankton to multiply rapidly, and the water body becomes discolored, smelly, and turbid, resulting in continuous deterioration of the water body, thus deteriorating the water body ecology. Obstruction and disruption of system and water functions. When the...
