Embodiment Construction

[0039] A kind of ecological pond effluent advanced treatment combined process for treating sewage provided by the invention, its main structure is as followsfigure 1 shown, including:

[0040] A roller grid machine 1, which realizes liquid-solid (or liquid-liquid) separation by utilizing the principle that components with different densities of suspensions (or emulsions) rapidly settle and stratify in a centrifugal force field. The centrifuge outlet water is pressurized by the booster pump 27, and is sprayed into the ecological pond 6 at high pressure under the effect of the shrinkage inlet pipe 26. The rotating speed of the roller grill machine can be controlled at 30-5000r / min.

[0041] In the ecological pond 6, the influent water is sprayed into the bottom of the ecological pond 6 under the action of pressure, and the carbon fiber flow filler 24 is continuously rolled and mixed under the action of the water flow. The fence 25 pours into the pond body above the ecological p...

Abstract

An ecological pond effluent deep treatment device comprises a drum grille machine; effluent is sprayed into the bottom in an ecological pond through a necking-down water inlet pipe; the effluent of the ecological pond goes into a turbulent-flow nano aeration backflushing screen filter pool; the effluent treated by the turbulent-flow nano aeration backflushing screen filter pool automatically flows into a nano aeration ablation device; the bottom of the nano aeration ablation device is provided with a mud discharge port; a part, above the mud discharge port, of the interior of the nano aeration ablation device is provided with a nano aeration disc; the nano aeration disc is connected with a nano O3 aerator; the nano aeration ablation device is provided with a temperature control instrument, and the temperature control meter is connected with and controls a temperature sensing control head and a heating zone placed inside the nano aeration ablation device. The invention also discloses a method for wastewater treatment by using the device.

Description

technical field [0001] The invention relates to a combined process for advanced treatment of effluent from an ecological pond, in particular to a device for advanced treatment of effluent from an ecological pond. [0002] The present invention also relates to a method for advanced treatment of the effluent of the ecological pond by using the above-mentioned device. Background technique [0003] The ecological pond is a kind of stable pond that uses aquatic plants and aquatic animals existing in natural water to treat sewage. The stabilization pond treatment system has been widely used in many countries, and our country has carried out research on a national scale since the 1980s. Although compared with the traditional activated sludge method, A2 / O method, oxidation ditch method, AB method, and ABC, SBR method, biofilm method, high-pressure membrane method that have appeared in recent years, it has the disadvantage of occupying a large area, but its The advantages of low in...
