Steam stripping ultraviolet coupling spray irrigation type ecological water purification system

Abstract

The invention discloses a steam stripping ultraviolet coupling spray irrigation type ecological water purification system. The system is characterized by comprising an ecological floating bed unit, a photovoltaic gas supply unit and ultraviolet steam stripping units; the ecological floating bed unit floats in water by virtue of self buoyancy, a photovoltaic gas supply unit is arranged in the center of the ecological floating bed unit in a penetrating manner, and a plurality of ultraviolet steam stripping units are arranged around the ecological floating bed unit in a penetrating manner; the ecological floating bed unit is composed of a floating body, plants and planting holes. The photovoltaic gas supply unit is composed of a photovoltaic assembly, an air compressor, an air delivery pipe, an aeration head and a breather pipe; each ultraviolet steam stripping unit is composed of a water inlet, a coupling pipe, an ultraviolet lamp and a sprinkling irrigation head. 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 aeration heads of the photovoltaic gas supply unit and the vertical flow guide configuration of the ultraviolet steam stripping 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 coupling effect of steam stripping oxygenation and ultraviolet radiation.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a stripping ultraviolet coupling sprinkler irrigation type 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 ...

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
