Zero-emission integrated culture tail water treatment device

Abstract

The invention discloses a zero-emission integrated culture tail water treatment device. A water pump, a mechanical filtering device, an anoxic biochemical bin, a pure nitrogen deoxidation device, a pure nitrogen source, an aerobic biochemical bin, a pure oxygen aeration device, a pure oxygen source, a sterilization and disinfection device, a control unit, an operation display unit, a sedimentationbin, a sludge advanced treatment bin and a filter press are arranged in a device shell; the device shell is further provided with a to-be-treated water inlet, a treated water outlet, a main drain outlet and a sludge outlet. According to the invention, a large amount of culture tail water can be discharged; anoxic and aerobic conditions of biochemical reaction are met; realization of up-to-standard emission requirements, pollutants degraded by the biochemical reaction can be deeply treated; almost zero emission is achieved, environmental pollution is greatly reduced; meanwhile, the running states or water quality monitoring data of all devices can be reflected in real time, a control program can be reset at any time or a certain device can be directly and manually controlled, monitoring ismore visual, and operation is more convenient and faster.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a zero-emission integrated aquaculture tail water treatment device. Background technique [0002] Nowadays, blue bath outbreaks in major lakes across the country and black and smelly rivers in urban areas are becoming more and more common, all of which reflect that the self-purification capacity of public water bodies is not enough to digest the substandard water discharged by agricultural or industrial production. pollute. A considerable part of the pollution in agricultural production is caused by the untreated discharge of aquaculture tail water. [0003] Aquaculture tail water is produced by aquaculture (including aquaculture ponds, factory workshops, etc.), and is discharged into external public waters and is no longer used for aquaculture. In the traditional aquaculture industry, the tail water of aquaculture is usually not treated, and it is directly ...

AI Technical Summary

Problems solved by technology

[0006] 1. Before the biochemical treatment process, the solid pollutants in the water body cannot be separated, thus affecting the effect of subsequent biochemical treatment;

[0007] 2. Failure to create the required hypoxic or anaerobic environment in the anoxic biochemical treatment process;

[0008] 3. In the process of aerobic biochemical treatment, the large amount of oxygen required cannot be provided to make the reaction more rapid and complete

[0009] 4. The entire device occupies a large area, and it is difficult to move the equipment after installation

[0010] 5. Although the treated effluent of aquaculture tail water does meet the discharge standard requirements, the sludge generated by filtration or sedimentation during the treatment process has not been treated in depth. If it is directly discharged, it will still pollute the environment
