Problems solved by technology

Generally speaking, the DO concentration of water body decreases with the increase of water depth. Due to the limitation of DO, the purification effect of aerobic microorganisms and aquatic animals and plants in water body is inhibited. Therefore, the oxygen enrichment effect of water body affects to a large extent. self-purification of water

Embodiment 1

[0025] (1) make floating bed frame 4 with bamboo or wooden strip, the diameter of bamboo or wooden strip is 3-6cm, and the length, width and height of frame 4 are successively 60-75cm, 40-45cm, 25-35cm, between each part Connect and fix with iron wire or three-hole bowl joint.

[0026] (2) Fix one deck stainless steel wire mesh 6 with tie wire or cable ties at the top, bottom and surroundings of the frame 4, the wire diameter is 0.8mm, and the mesh is 13mm.

[0027] (3) if figure 1 As shown, the oxygen-enriched multistage aerobic-anaerobic reaction unit 2 is composed of an aerobic zone 11 and an anaerobic zone 12 in the middle of the frame 4 separated by a separator 8 . Use stainless steel wire mesh to form a straight triangular prism separator 8, and line the inner surface with a layer of non-woven fabric to prevent the filler from leaking, and leave one end open for filling. The filler is a mixture of activated carbon and zeolite with a volume ratio of 1:1. The particle si...

Abstract

The invention relates to a method or a process for treating polluted water purification. An automatic water oxygen-rich composite floating bed for strengthening biological carbon and phosphorous removal effect is characterized by comprising a plant absorption and utilization unit (1), an automatic water oxygen-rich multistage aerobic-anaerobic reaction unit (2), a microbial film-forming reinforcement unit (3) and a framework (4); stainless steel wire gauzes (6) are fixed on the top, the bottom and the four sides of the framework (4); the plant absorption and utilization unit (1) consists of a support matrix (7) arranged on the top of the framework and a floating bed plant (5); and the floating bed converts the horizontal water flow passing through the automatic water oxygen-rich multistage aerobic-anaerobic reaction unit into N-shaped water flow so as to realize oxygen enrichment of water in an aerobic area on the middle layer of the floating bed and promote the self-cleaning function of the water of the middle layer.

Description

technical field [0001] The invention relates to a treatment method or process for purifying polluted water, in particular to a treatment method for in-situ purification of non-point source polluted water by using oxygen-enriched composite floating bed technology to enhance the effect of biological denitrification and phosphorus removal. Background technique [0002] Among the many measures to control non-point source pollution, the ecological floating bed has been proved to be a remarkable technical measure. Ecological floating bed is a sewage ecological engineering treatment technology that uses soilless cultivation technology and adopts modern agronomy and ecological engineering measures. This technology reduces the nutrients such as nitrogen and phosphorus in the water body through the absorption and adsorption of plant roots and the material transformation of the root ecosystem, so as to achieve the double effect of purifying the water body and the water surface landscap...
