Steam stripping ultraviolet and plant growth effect combined zigzag water purification system

Abstract

The invention provides a steam stripping ultraviolet and plant growth effect combined zigzag flow water purification system. The system is characterized by comprising a floating bearing unit, a power zigzag flow unit, a steam stripping ultraviolet unit and a plant growth zigzag flow unit; the floating bed supporting unit is composed of a floating bed and plants; 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. The steam stripping ultraviolet unit consists of an overflow hole, a steam stripping ultraviolet tube, an ultraviolet lamp and a water inlet hole; the vegetation zigzag flow unit is composed of an inflow hole, a vertical vegetation pipe, a biofilm carrier and an outflow hole. The system has the obvious advantages of being high in space utilization rate, easy and convenient to operate and maintain, high in comprehensive benefit and the like, and through arrangement of the aeration head and the water injection nozzle of the power zigzag flow unit and the vertical flow guide structure of the steam stripping ultraviolet unit and the vegetation zigzag flow unit, 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 steam stripping ultraviolet and plant growth effect.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a wandering water purification system combined with stripping ultraviolet rays and vegetation effects. 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 numbe...

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
