Embodiment Construction

[0028] The object of the present invention is to provide a kind of combination process of advanced treatment of aquaculture wastewater by ecological method, which can quickly remove pollutants (such as: organic matter, inorganic matter, microorganisms, heavy metals, etc.) in sewage.

[0029] The present invention provides a combined process for the advanced treatment of aquaculture wastewater by an ecological method for treating sewage, and its main structure includes:

[0030]A roller grid machine 1 is a semi-enclosed shell 34 composed of iron plates rolled into two cylinders with a section of mesh plate sandwiched between them. The semi-enclosed shell 34 is fixed on the support 35 through bearings 33. The semi-enclosed shell The bottom of the shell 34 is a water storage tank, and the needle cleaner 3 is fixed on the upper end of the semi-closed shell 34 and one side of the drum sieve. Sewage flows through the pores of the grille drum and falls directly into the storage tank;...

Abstract

The invention relates to a combined device for deeply treating breeding wastewater by adopting an ecological method. The combined device comprises a roller grille machine, an anaerobic purification tank, a slow soil seepage system, a turbine screening filter tank and a nanometer aerated grit chamber. The invention also discloses a method for treating the breeding wastewater by utilizing the combined device. The combined device disclosed by the invention has the advantages of small occupied area and convenience for operation; effluent water treated by the combined device has the advantages of high transparency, good water quality, short reaction period, small investment, quick effect, microbe and ova killing and water bloom generation prevention, and various pollution indexes reach the national primary standard after the effluent water is purified.

Description

technical field [0001] The invention relates to a combined device for advanced treatment of aquaculture wastewater by an ecological method. [0002] The invention also relates to a method for treating pollutants such as organic matter, inorganic matter, microorganisms, pathogenic bacteria and the like in the aquaculture wastewater by using the device. Background technique [0003] Aquaculture wastewater is high-concentration organic wastewater rich in a large number of pathogens. It is not suitable for direct discharge into water bodies or long-term storage. Once washed into water bodies by rainwater, it can cause serious deterioration of surface water or groundwater quality. The impact on surface water is mainly manifested in that after a large amount of organic matter enters the water body, the decomposition of the organic matter will consume a large amount of dissolved oxygen in the water and make the water body smelly; Continue to decompose under oxygen conditions, and ...
