Embodiment Construction

[0039] The invention provides a combined process for advanced treatment of effluent from an ecological pond for treating sewage, and its main structure is as follows:figure 1 shown, including:

[0040] A drum grid machine 1 realizes liquid-solid (or liquid-liquid) separation by utilizing the principle of rapid sedimentation and stratification of components with different densities of suspension (or emulsion) in a centrifugal force field. The centrifuge effluent is pressurized by the booster pump 27 , and is sprayed into the ecological pond 6 under high pressure under the action of the water inlet pipe 26 . The rotating speed of the drum grid machine can be controlled at 30-5000r / min.

[0041] In the ecological pond 6, the influent water is sprayed into 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. Under anoxic conditions, the pollutants are degraded, and the pretreate...

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 ecological ponds, in particular to a device for advanced treatment of effluent from ecological ponds. [0002] The present invention also relates to a method for advanced treatment of effluent from an ecological pond using the above device. Background technique [0003] Ecological pond is a kind of stable pond that uses aquatic plants and aquatic animals in natural water to treat sewage. Stabilizing pond treatment systems have been widely used in many countries, and my country has carried out research nationwide 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, etc., which have appeared in recent years, it has the disadvantage of large footprint. The advantages of less investment, low operating costs, and simple operation a...
