Ultraviolet-enhanced steam stripping zigzag ecological water purification system

Abstract

The invention provides an ultraviolet-enhanced steam stripping zigzag ecological water purification system. The system is characterized by comprising a floating bearing unit, a power zigzag flow unit and ultraviolet ecological units; the floating bearing unit floats in water by virtue of self-buoyancy, the center of the floating bearing unit is provided with the power zigzag flow unit in a penetrating manner, and the periphery of the floating bearing unit is provided with the ultraviolet ecological units in a penetrating manner; the floating bearing unit is composed of a floating body and a plant; the power zigzag flow unit is composed of a solar assembly, a machine body, an air conveying pipe, an aeration head, a breather pipe, a water suction opening and a water spraying opening. Each ultraviolet ecological unit is composed of an overflow hole, a pipe body, an ultraviolet lamp and a water inlet hole. Compared with the prior art, the system has the obvious advantages of being high in space utilization rate, simple and convenient to operate and maintain, relatively high in comprehensive benefit and the like, and through arrangement of aeration heads and water injection nozzles of the power zigzag flow unit and the vertical flow guide structure of the ultraviolet ecological units, the zigzag flow circulation effect of the water body is enhanced, and dissolved oxygen of the water body is increased; meanwhile, the sewage purification effect is enhanced through the combined action of plant root systems and ultraviolet radiation.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an ultraviolet-enhanced stripping swirling flow ecological water purification system. Background technique [0002] Ecological floating bed technology is one of the most commonly used and most extensive in-situ restoration technologies in the field of surface water purification. Due to the advantages of no land occupation, low cost, and easy management, the traditional ecological floating bed has a wide range of engineering applications in the fields of urban black and odorous river restoration, eutrophic lake treatment, and urban landscape water purification. However, the defects of traditional ecological floating beds or enhanced ecological floating beds proposed by some experts and scholars are gradually exposed. [0003] First, the biofilm of traditional ecological floating beds only attaches to plant roots or planting substrates, resulting in a limited number and activity of...

However, the defects of the traditional ecological floating bed in practical application or the enhanced ecological floating bed proposed by some experts and scholars are gradually exposed.

[0003] First, the biofilm of traditional ecological floating beds only attaches to plant roots or planting substrates, resulting in a limited number and activity of microorganisms, thus limiting the purification efficiency of traditional ecological floating beds; second, the hydraulic circulation conditions of traditional ecological floating beds are insufficient , especially for stagnant or slow-flowing surface water bodies, traditional ecological floating beds can only statically treat the surface water bodies where they are located, but have almost no purification effect for long-distance or deep water bodies. For this reason, experts and scholars in related fields have proposed A hydraulic circulation system is introduced into the traditional ecological floating bed, such as: river channel axial flow pump, plug-flow aeration, etc., but this method is expensive and consumes a lot of power, so it is not easy to promote; third, the traditional ecological floating bed or enhanced ecological Floating beds have the problem of low space utilization, that is, only the space near the water surface is used for purification, but the underwater space of the floating bed is not fully utilized
