Sprinkling irrigation circulating flow type ultraviolet enhanced ecological water purification system

Abstract

The invention discloses a sprinkling irrigation circulating flow type ultraviolet enhanced ecological water purification system. The system is characterized by comprising a buoyancy bearing unit, a circulating zigzag flow unit and vertical pipe combination units; the buoyancy bearing unit floats in water by virtue of self buoyancy, the center of the buoyancy bearing unit is provided with the circulating zigzag flow unit in a penetrating way, and the periphery of the buoyancy bearing unit is provided with a plurality of vertical pipe combination units in a penetrating way; the buoyancy bearing unit is composed of a buoyancy carrier and emergent aquatic plants. The circulating zigzag flow unit is composed of a solar assembly, a water pump, a water inlet and a water outlet. Each vertical pipe combination unit is composed of an inflow hole, a vertical combination pipe, an ultraviolet lamp and an outflow hole. Compared with the prior art, the system has the obvious advantages of being high in space utilization rate, easy and convenient to operate and maintain, remarkable in purification effect and the like, and the water outlet arrangement of the circulating zigzag flow unit and the vertical flow guide structure of the vertical pipe combination units enhance the zigzag flow circulating effect of the water body and increase dissolved oxygen of the water body; 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 spray irrigation circulation type ultraviolet enhanced 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 ac...

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
