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 the floating bed frame 4 with bamboo or wooden strips, the diameter of the bamboo or wooden strips is 3-6cm, the length, width and height of the frame 4 are 60-75cm, 40-45cm, 25-35cm in turn, and between each part Use iron wire or three-hole bowl joint to connect and fix.

[0026] (2) A layer of stainless steel wire mesh 6 is fixed on the top, bottom and surrounding of the frame 4 with wire or wire ties, the wire diameter is 0.8mm, and the mesh hole is 13mm.

[0027] (3) If figure 1 As shown, the water body is composed of an oxygen-enriched multi-stage aerobic-anaerobic reaction unit 2 which is composed of a separator 8 dividing the middle part of the frame 4 into an aerobic zone 11 and an anaerobic zone 12 . A straight triangular prism separator 8 is surrounded by stainless steel wire mesh, and the inner surface is lined with a layer of non-woven fabric to prevent the leakage of the filler, and one end is temporarily opened to fill the filler. The particle s...

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 asupport 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 functionof the water of the middle layer.

Description

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