Steam stripping zigzag flow system based on ultraviolet oxygenation enhanced water purification

Abstract

The invention discloses a steam stripping zigzag flow system based on ultraviolet oxygenation enhanced water purification. The steam stripping zigzag flow system is characterized by comprising a floating load unit, a steam stripping unit and ultraviolet units; the floating load unit floats in water by virtue of self buoyancy, a steam stripping unit is arranged in the center of the floating load unit in a penetrating manner, and a plurality of ultraviolet units are arranged around the floating unit in a penetrating manner; the floating load unit is composed of a floating body and a plant; the steam stripping unit consists of a solar assembly, an air compressor, an air delivery pipe, an aeration head and a breather pipe; each ultraviolet 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 high space utilization rate, simplicity and convenience in operation and maintenance, relatively high comprehensive benefit and the like, and through the arrangement of the aeration heads of the steam stripping unit and the vertical flow guide configuration of the ultraviolet unit, the zigzag circulation effect of the water body is enhanced and the 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 a stripping and swirling flow system based on ultraviolet oxygenation to strengthen water purification. 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 numb...

Problems solved by technology

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
